Subject of Present Invention and Technical Field

This invention is related to the automatic air purger mechanism in water installations. The invention is particularly related to the automatic air purger mechanism used in air purging systems used in water installations.

State of the Art

As technology develops, conventional plumbing is also developing. In this context, beyond circulating only water and liquid for specific purposes in water installations, there are also important developments in enhancing the quality of water or liquid. Within this scope, in the facilities where liquid or water circulates, the amount of air or gas in the liquid increases especially in the pipes, reservoirs and transferring areas in time. These air and gas are discharged with the air relief systems known as “degasifier” in the market.

In the state of the art, in the air relief systems (degasifiers), there is a mechanism called“purger” which purges air out while relieving the air classically. This mechanism is generally called as air purger, however it is also sort of a non-return valve. Since the air purgers in the state of the art are configured only for purging the air out, they work as a non-return valve in some way. However, the level of water or liquid in the air relief is important. Depending on the water or liquid level, the air is either present inside or it is relieved. The air is relieved while water or liquid level is increasing, and it is required for the water to stay inside. And for keeping the water inside, some air stays inside or the water leaks out if the water level is too high. Such a situation makes it inefficient to purge the air out.

Technical Problems to Be Solved By The Invention

The subject of the invention is that air purger mechanism allows opening and closing the valves in the mechanism by rising and descending of the float according to the level of water or liquid, hence only air purging (air release) is provided, water or liquid release is prevented and it is aimed to prevent air intake from outside.

One advantage of this invention, the air purger mechanism, is to provide automatic opening and closing according to the water or liquid level in the air relief system.

Another advantage of this invention, the air purger mechanism, is to open and close air purging valves in the air purger mechanism by triggering each other, and ensuring a rhythmic and error-free motion thanks to the return motion with the spring, and obtaining maximum efficiency.

The subject of this invention, the air purger mechanism, will be better understood via figures below. Brief Description of the Figures

The subject of this invention, air purger mechanism, is used in connection with air purging systems from the system which is particularly used in water installations and which is also named as“degasifier”. The invention is basically used in the air relief system that is related with discharging the air in water installations. Flowever, it is not only for discharging air from water, it is a mechanism that will be able to discharge any gas inside any liquid. For a better understanding, the definition“degassing” will be used. Flere liquid means all kinds of liquids, notably water; and gas means all kinds of gases, notably air; and it should not be limited with water and air. On the other hand, the air purger mechanism is the valve system where the air outlet is provided in the air relief system known as“degasifier” in the market. Again here, naming the mechanism which is used for relief as valve should not be limiting.

The subject of this invention, air purger mechanism, is in connection with the liquid tank (2) in the air relief system (1 ) shown as a general scheme in Figure-1. The structure of liquid tank (2) is shown in the images in Figure-2 and Figure-3. In general, the liquid (9) taken into the liquid tank (2) is degassed inside and purged out in the system. Discharging event is ensured with the air purger mechanism. The subject of this invention, air purger mechanism is seen in sectional and perspective view in Figure-4. In Figure-5 and Figure-6, cross sectional view of mechanism is seen while the float level is above and below.

Present invention is basically an air purger mechanism located in at least one liquid tank (2) in an air relief system (1 ) characterized in that;

It includes at least one air purger mechanism housing (3) that is located in a liquid and includes the liquid (9) inside the mentioned liquid tank (2), at least one float (4) that is located in mentioned mechanism housing (3) and contacting the liquid, at least one motion diverter (5) that is in contact with mentioned float (4) and that transmits its motion by changing direction, at least one valve housing (8) located on top and side part of mentioned air purger mechanism housing (3), a first valve (6) that is dynamically engaged with the mentioned motion diverter (5) inside and one side of mentioned valve housing (8), a second valve (7) and a spring (10) that is located inside and on the other side of mentioned valve housing (8).

The subject invention includes liquid reservoir (3d) that is in connection with the liquid tank (2) in the bottom part of air purger mechanism housing (3) in the air purger mechanism and that includes some part of liquid (9), and valve seat (3c) where the valve housing (8) is located on top side. Air purger mechanism (3) includes a bottom housing (3a) and a top housing (3b) which is connected tightly and impermeably with the mentioned bottom housing (3a). Air purger mechanism housing (3) can alternatively be monolithic or mono-block. Float (4) is hollow or filled with material having less specific gravity than liquid’s specific density, and it includes a float connection hook (4a) on top. Float (4) will be on top of the liquid (9), and due to buoyancy, it will rise with the rising water level and lower as the water lever lowers. Here the Float (4) is in Float moving direction (x-y), that is below and above. Here the Float moving direction (x-y) does not show a direction, it shows both up and down motion or either of them.

In the subject invention, air purger mechanism; valve housing (8) is located in the valve seat (3c) and inside it, most basically the first valve (6), second valve (7) and spring (10) are located. It includes valve housing joint area (8a) that is a joint connection area for the motion diverter (5) in the valve housing (8) to make partial circular motion in a swinging manner, empty space (8b) where the gas passage will be ensured and where first valve (6) and second valve (7) are located, and spring positioning area (8c) where the spring (10) is located. Motion diverter (5) is a machine component that changes the direction of the motion which transfers the motion in the gravity direction, that is in the direction of buoyancy in the float (4) to the first valve (6) which is connected to it. It includes diverter moving joint (5c) which connects the motion diverter (5) to the valve housing joint area (8a) providing it a constant but partial circular motion, and which provides the free contact with diverter hook (5a) that is connected to the diverter fixed joint (5b), which is a joint connection with the float (4), that gets starting and rotating force from the mentioned float (4) and first valve (6). Swinging motion of motion diverter (5) is in the same direction with diverter’s motion (m-n). First valve (6) is located in the empty space (8b) and inside air purger mechanism (3). It includes diverter connection area (6a) that provides a free and joint connection with diverter moving joint (5c) of first valve (6), first valve sealing seat (6b) that includes seal (1 1 ) which provides sealing in the empty space (8b) and first valve motion limiter (6c) which is a diameter protrusion that limits the movement of first valve (6). The first valve (6) moves in the moving direction of first valve (a-b) with the force and start received by motion diverter (5) from float (4). Second valve (7) is located in the empty space (8b) and in the part where air purger mechanism (3) opens out. It includes spring winding area (7a) where the spring (10) of second valve (7) is located, second valve sealing seat (7b) that includes the seal (1 1 ) which provides sealing in the empty space (8b), and second valve motion limiter (7c) which is a diameter protrusion that limits the movement of second valve (7). The air is purged out by the second valve (7) making a linear movement in the second valve moving direction (e- f) with the effect of air pressure from inside and the spring (10) which is connection to it. Actually, the first valve (6) and the second valve (7), as will be explained below, are circular and bar-shaped circular machine elements that allow air inlet and outlet. Here the sealing is provided with seal (1 1 ), but if the production is made with high precision, there may be no need for seal.

In this invention of air purger mechanism, when there is no liquid (9) in the liquid reservoir (3d), the float (4) is down (Figure-6). The liquid (9), whose gas or air will be discharged, raises in the liquid tank (2) and then fills into liquid reservoir (3d) and its level increases. With the rising liquid (9) level, the float (4) on top of it starts to go up with the effect of buoyancy (Figure-5). The float valve (4) rises as it moves in float moving direction (x-y). In that case, it starts to rotate the motion diverter (5), which is connected to it from the float connection hook (4a), in the motion diverter moving directions (m-n). Meanwhile, the first valve (6) is free in the empty space (8b) and gas or air passage through the empty space (8b) is allowed. As the gas or air, which remains on top of the raised float (4), is compressed; it is purged out from this empty space (8b). At this stage, the first valve (6) is already open, and gas or air pressure force of second valve (7) pushes the string (10) and the gas or air passage is allowed. As the Float valve (4) goes up, motion diverter hook (5a) of motion diverter (5) rises, therefore it rotates with partial circular motion in diverter moving directions (m-n) around the diverter fixed joint (5b). The limit of this rotation is provided with the first valve (6) proceeding to the exit and by preventing also the liquid passage together with the gas or air passage. When there is no gas or air in the empty space, the second valve (7) is also closed with the force of spring (10) and gas or air intake is prevented. When the gas or air in the liquid (9) is discharged, there will be no liquid (9) in the liquid tank (2), and consequently in the liquid reservoir (3d). In that case, the float (4) goes down and the first valve (6) opens. As the float (4) liquid level increases, the compressed gas passes the first valve (6) and the second valve (7) and goes out. It is closed again in the uppermost and the cycle is maintained. This Invention’s Form of Application in the Industry
