Description:
TITLE OF THE INVENTION

Combination Spill Prevention Valve Actuator Device

FIELD OF THE INVENTION

This invention relates to a spill prevention valve actuator device for use in storage tanks that store oil, water or other fluids to prevent the accidental discharge of the stored material during fluid transfer as well as minimize theft of said fluid by an unauthorized user and minimize injury to the user. BACKGROUND OF THE INVENTION

The transfer of large volumes of fluids, particularly petroleum products, from larger storage containers to smaller, mobile containers often requires the use of a number of fittings and hoses with couplers and valves. Prior art couplers use locking cams that attach the transfer hoses to stationary valves attached to storage tanks. However, these locking cams are tricky to use, requiring manual manipulation of the cams by the worker attempting to connect the hose and transfer the fluid. Current locking cam arms are of a lever and/or ratchet design that wear easily and become sloppy, causing them to disengage unexpectedly and cause physical injury to the worker, i.e. severing of fingers. Current systems involve the use of external equipment such as ratchets, wrenches and the like requiring the worker to use two hands or at times requiring two or more workers to connect the couplers. In addition, the absence of an interlock feature between the couplers and the valve means that there is always a risk during fluid transfer that the couplers can disengage while the valve remains open, which can result in a fluid spill, environmental damage and costly clean up.

There remains a long-felt need for a spill prevention device that is efficient, compact, and of a straightforward one motion design that allows ease of use and reduces risk of personal injury and environmental damage.

There remains a long-felt need for a spill prevention device that will only allow flow of fluid when the connection is secure.

There remains a need for a device that also minimizes access and transfer of fluid by an unauthorized user. There remains a need for a device that may fit onto existing valves structures to minimize spills and/or accidents during transferring of fluids and minimize unauthorized access to fluids.

There remains a need for a device that will allow for a disconnection which results in little to no fluid spillage.

There remains a need for a device which locks down and secures the connection with the hose before the valve is actuated and opened in one fluid motion.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

With reference to the Figures, the spill prevention device 10 comprises a valve actuator 20 comprising a handle 25, locking cams 30 and 35 integral with the actuator 20, a butterfly valve 40 controlled by the valve actuator handle 25. With the valve actuator 20 in a first (closed) position (Figures 1 , 3, 8, 9 and 10), when the handle 25 is moved in an upright position, the butterfly valve 40 closes and the cams 30 and 35 disengage from the locking tabs 60 and 65 to allow the second coupler 70 to be released from the first coupler 80. In this way, because the butterfly valve 40 is closed before the second coupler 70 is disengaged, spillage of any fluid is eliminated.

With reference to Figures 2 and 4B - 7, when the actuator 20 is moved to a second position, the handle 25 has been moved downward and the butterfly valve 40 has opened and cams 30 and 35 have engaged with the locking tabs 60 and 65 to secure the second coupler 70 to the first coupler 80 to allow fluid, such as oil, to flow through the valve from a first location, such as an oil tank (not shown), to a second location, such as a truck- mounted oil tanker (not shown) . Further, cams 30 and 35 have engaged with coupler seal (not shown) for sealing the connection between the first coupler 80 and second coupler 70. The coupler seal may be a stock rubber ring commonly used in many sealing applications. In this way, the second coupler 70 cannot inadvertently detach from the first coupler 80 when the butterfly valve 40 is open resulting in no fluid being spilled during fluid transference. Figure 4B shows the actuator in between an open and closed position.

The cams 30 and 35 are arcuate in shape in this embodiment allowing for engagement and disengagement with the locking tab s 60 and 65 with minimal effort.

The valve 40, valve body 100 and couplers 70 and 80 are fabricated from material that is resistant to degradation from the fluid that contacts them. In certain embodiments, the valv e, valve body and couplers are fabricated from stainless steel. The sizing of the valve, valve body and couplers is typically four inches inner diameter. The coupler seal may be made from any material known in the art for seals. The handle 20 is made from the same material as the valve, valve body and couplers or a different material. For ease of fabrication the cams 30 and 35 are made from the same material as the handle 20.

The spill prevention device 10 operates as follows: a first location is provided which has the device 10 connected thereto, the device 10 comprising a valve body 100 comprising a valve actuator handle 20, a butterfly valv e 40 controlled by the handle 25, locking cams 30 and 35 integrally connected to the handle 25 and a first coupler 80; a second location is provided which has a second coupler 70 with locking tabs 60 and 65 connected to said second location; the first coupler 80 and the second coupler 70 are loosely connected and the valve actuator handle 25 is pulled in a downward direction from a first position to a second position to simultaneously engage locking cams 30 and 35 with locking tabs 60 and 65 to lock the couplers 70 and 80 together and open butterfly valve 40; and the fluid to be transferred flows from the first location to the second location. Once the fluid transfer has been completed, the valve actuator handle 25 is pushed in an upward direction from the second position to the first position to simultaneously close the butterfly valve 40 and disengage the locking cams 30 and 35 from the locking tabs 60 and 65 to release the couplers.

The valve actuator may be connected to an existing fluid tank valve without any further modification. The device may be fireproof and meet API specifications as required. The device is comprised of minimal parts, a first coupler comprising the handle and valve, and a second coupler comprising a nipple for a hose.

Referring now to Figures 11 and 12, there is provided a further embodiment of the present invention. In particular, there is provided a device 120 that may be mounted onto an existing valve 140 allowing for retrofitting thereof. The device 120 consists of a valve actuator 150 having a first valve actuator handle 160 and a pair of actuator arms 170, 170'. In this embodiment, each actuating arm 170, 170', is arcuate in shape, allowing for the secure engagement of the engagement tabs 180, 180' of the nozzle 190 when the first valve actuator handle 160 is moved towards the nozzle 190 once the nozzle 190 is initially engaged with the valve flange 200. The valve flange 200 serves to provide a seal with the nozzle 190. The valve flange 200 has a key, in this embodiment a substantially elongated rectangular portion 210. The valve flange key 210 may be received in the valve flange key receiver 191 of the nozzle 190. In this embodiment, an elongated slot running parallel to the axis of the nozzle 190. In this manner, only a valve flange 200 with a key 210 with a male configuration may be securely engaged with a nozzle 190 having a corresponding flange key receiver 191 with a female configuration corresponding to the male configuration. This security feature may avoid theft of fluid by an unauthorized user and may also avoid the transfer of a fluid not meant for transfer to a second location. In another embodiment, the valve flange has a female configuration and the nozzle has a male configuration. In yet another embodiment, the valve flange and nozzle have a combination male/female configuration allowing for secure engagement when the actuating arms 170, 170' are engaged with the engagement tabs 180, 180'. In order to secure the nozzle to the valve flange, the user engages the nozzle 190 to the valve flange 200, aligning the key 210 with the key receiver 191 moving the handle 160 towards the nozzle allowing the actuator arms 170, 170' to move and engage with the engagement tabs 180, 180' of the nozzle 190 and engaging the key 210 with key receiver 191. This safety feature may avoid accidents when transferring fluids. As best seen in Figures 16, 20 and 21 , another embodiment of the key and key receiver is depicted. In this embodiment the key receiver is an elongated slot comprising a first substantially straight section 192 connected by a connector 193 to a second substantially straight section 194 and the key is peg shaped 21 1. In this embodiment, the first substantially straight section 192 and said substantially second straight section 194 are substantially parallel to each other but spaced apart from each other by a connector 193 , wherein said connector 193 is substantially normal to each of said first and second sections 192 and 194 respectively. In this embodiment, when the nozzle 190 is to be disconnected from the valve flange 200, the user must pull the nozzle 190 away from the key 21 1 and along the second section 194 towards the connector 193, turn the nozzle 190 in order to move the key (detent) 21 1 along the connector section 193, and continue pulling the nozzle 190 along the first section 192 and away from the key 21 1. This turning action of the nozzle 190 provides for a vacuum release allowing any fluid in the nozzle 190 to enter the second location (eg. truck) and reduce any unwanted spillage of fluid during the disconnection process. In yet another embodiment, as best seen in Figures 1 8 and 19, the device 120 further comprises a handle lock, in this embodiment a ball 220 and spring plunger 230 proximate said handle 160 urging said handle 160 to the locked position (i.e. a closed valve) reducing unwanted opening of the valve. As best seen in Figure 18, the handle 160 is in the closed position, and the ball 220 of the ball and spring plunger 230 is urged against the hole 240 in the handle to receive the ball 220. The ball 220 and spring plunger 230 are secured on the device by a ball and spring plunger plate 250 proximate the handle 160. When the user rotates the handle towards the nozzle, the ball is retracted from the hole allowing the handle to continue rotating towards the nozzle. When the user is ready to close the valve, the user retums the handle towards the first position and knows the valve is closed when the ball is received in the hole. In one embodiment, the tension on the ball and spring plunger may be adjusted as needed. The device 120 may be fitted over an existing valve stem, as best seen in Figures 1 1- 15. In this embodiment, handle arms 161 and 162 engage valve stems 16 and 162' respectively of valve 140. Particularly, each handle arm 161 and 162 are flexible ID allow valve stem 16 and 162' to engage with valve stem receivers 163 and 164 respectively. In this embodiment, valve stem 16 is substantially cylindrical in shape and valve stem receiver 163 is a substantially cylindrical void complementing valve stem 16 . In one embodiment, valve stem receiver 163 (As best seen in Figures 18-20) includes a bearing common to a person of ordinary skill in the art, to facilitate rotation and reduce uneven wear and uneven opening of the valve. Valve stem 162' is cylindrical in shape and valve stem receiver 164 is substantially void complementing valve stem 162'. In this embodiment valve stem receiver 164 includes a resilient bushing 165, which provides for slack technology ensuring the valve arms 170 and 170' are engaged with the engagement tabs 180, 180' before the valve is opened. Due to the resilient bushing 165 and the gap 164' formed between the bushing 165 and receiver 164 (as best seen in Figures 12 and 17), the valve stem 161 ' and 162' lag behind the handle 160 movement (in one embodiment, by several degrees) ensuring the valve 140 is not opened until the valve arms 170 and 170' are fully engaged with the engagement tabs 180 and 180' respectively. In one embodiment the slack technology further minimizes small leaks and spillage by ensuring that the valve is not opened even marginally until the hose fitting is securely locked into place. In one embodiment, bushing 165 is made of a casted alloy, which is resilient.

Referring now to Figure 13, there is provided a back view of the device when the valve is in the closed position. Referring now to Figure 14, there is provided an exploded view of the handle and nozzle.

As many changes can be made to the preferred embodiment of the invention without departing from the scope thereof, it is intended that all matter contained herein be considered illustrative of the invention and not in a limiting sense.
