DRIP IRRIGATION SYSTEM HAVING PRESSURE REDUCING MEMBER

TECHNICAL FIELD

The present invention is related to pressure irrigation systems (drip and sprinkler irrigation), which have main distribution pipe balancing the pressure and flow rate in supplying liquid in the fields such as agricultural landscape, mining and construction.

STATE OF ART

Supplying the water that is required by the plants, but cannot be provided by means of natural raining is called irrigation and the most common method used is pressure irrigation (sprinkler and drip irrigation).

The main principle in the pressure irrigation systems is to give small amount of irrigation water to the area where only plant roots are grown, by means of pressure pipe and drippers at frequent intervals every time without causing any stress arising from lack of moisture in the plant.

In the present systems, when the pressure arises, side (lateral) pipes may burst or unbalanced water or liquid distribution may be experienced. The product loss or product fluctuation, namely, product wastage may increase due to the burst in side (lateral) pipes or unbalanced water or liquid distribution. Moreover, energy costs increase and frequent breakdowns are experienced and thus, the parts are deformed and labor increases.

Sometimes, in order to reduce the pressure, switch from a main pipe with a large diameter to a main pipe with a smaller diameter is performed by reducing the pressure and from here, water or liquid flow is supplied to side (lateral) pipes and thus, investment costs increase.

In the utility model search relating to the prior art, an application numbered TR 2009/01367 and titled "Pressure reducer and balancer for pressure and drip irrigation systems" has been found. The abstract of the application is as follows; "In order to be used in pressure reducers and balancers that are used in pressure irrigation systems and has an outer body having water inlet, water outlet, iniet-outlet connection member and protective cover, the present invention comprises at least one balancer body that remains within said protective cover, consists of inlet pipe having inlet pipe groove thereon and outlet pipe having outlet pipe groove thereon, comprises a pushing member housing provided between said grooves, and is positioned at said inlet-outlet connection member, and flexible inlet and outlet pipes positioned within said pipes, and at ieast one pushing member that is pushed by said flexible outlet pipe by means of outlet pipe groove and applies pressure on the flexible inlet pipe by means of inlet pipe groove when it is pushed."

Based on the state of art, the need for disclosing a heating and cooling machine for solving the abovementioned problems is clear. The present invention has been disclosed for solving the abovementioned problems.

DETAILED DESCRIPTION OF THE PRESENT INVENTION

The present invention is related to drip irrigation systems comprising main distribution pipe (1) balancing the pressure and flow rate in supplying the liquid in the fields such as agricultural landscape, mining and construction, characterized in comprising main passage body (2) having liquid passage channel (2.1) provided on said main distribution pipe (1), gasket (4) that covers the liquid inlet in accordance with the pressure of liquid, and determines how much liquid will be passed, a pressure balancing member (6) including liquid channels (5) having a liquid channel inlet hole (5a), liquid channel outlet hole (5b), and gasket hole (5c), and an intermediate connection pipe (13) having lateral pipe connection member (7) and lateral pipe outlet (8).

Figure 1 is the perspective view of the novelty in the pipes having pressure reducing member and flow rate balancing member in the pressure irrigation systems according to the present invention. In the Figure, main distribution pipe (1), lateral pipe liquid passage channel (2.1), gasket (4), liquid channels (5), pressure balancing member (6), and an intermediate connection pipe (13) having lateral pipe connection member (7) and lateral pipe outlet (8) are illustrated. Here, t-pipe is preferably used as intermediate connection pipe (13) and elbow and different pipes may also be used. Liquid is transferred to lateral pipes (9) by adapting the intermediate connection member (13) into the fixing gap (1.1) on the axis x-y provided on the main distribution pipe (1). Drip irrigation is performed by means of drip holes (10) formed on the lateral pipes (9). Sprinkling process is performed directly through the main distribution pipe (1).

The excessive water or liquid transferred is slowed down and controlled passage is enabled thanks to stopping the pressure water or liquid by means of gasket (4). Gasket (4) covers the liquid inlet in accordance with the pressure of water and determines how much water will be returned and be transferred to the lateral pipes (9). If the pressure is high, the gasket (4) is closed much more and provides less water passage, and if the pressure is lower, it is closed slightly and enables more water passage.

The liquid channels (5) slow down the liquid flow and balance the pressure and flow rate. The pressure balancing member (6) includes the gasket (4) and other systems on the main distribution pipe (1), and interconnects the lateral pipe connection member (7) and main distribution pipe (1).

The connection member that can be in the shape of intermediate connection pipe (13) comprising the lateral pipe outlets (8) thereon, and have different outlet numbers, is called lateral pipe connection member (7). Water or liquid is transferred to the lateral pipes (9) with smaller sizes by means of lateral pipe outlet (8). The intermediate connection pipe (13) is preferably t-pipe or elbow pipe.

Figure 2 is the perspective view of the novelty in the pipes having pressure reducing member in the pressure irrigation systems according to the present invention together with the lateral pipes (9). In the Figure, main distribution pipe (1), lateral pipe liquid passage channel (2.1), sprinkler (3), gasket (4), liquid channels (5), pressure balancing member (6), lateral pipe connection member (7), lateral pipe outlet (8), lateral pipe outlet (9) and drip hole (10) are illustrated.

The depressurized liquid is pressed towards the lateral pipes (9) through the lateral pipe outlets (8) and the required irrigation process is performed by means of drip holes (10) and sprinkler (3). The water or liquids received through the main distribution pipe (1 ) is transferred to lateral pipe liquid passage channel. The process step performed before transferring the liquid to the lateral channels in accordance with the nature thereof and pressure received, the pressure and flow rate of the fluid are balanced via gasket (4). Then, it is passed through the liquid channels (5) and liquid flow rate is adjusted in accordance with the pressure. The pressure balancing member (6) comprises all of the other members therein and performs one of the main functions in the main distribution pipe. The water or liquid, which is passed through the liquid channels (5), and the pressure of which is balanced, is directed towards the gasket hole (5c) and from here, passes towards the lateral pipe connection member (7). The liquid directed to lateral pipe connection member (7) in a balanced manner by exceeding the gasket (4), is transferred to lateral pipes (9) and thus to liquid spraying holes (10) thanks to lateral pipe outlet (8).

In the Figure 3, main distribution pipe (1), gasket (4), liquid channels (5), pressure balancing member (6), lateral pipe outlet (8), lateral pipe (9), main pipe locking mechanism (11), main pipe liquid inlet (12) and liquid flow directions (X and Y) of the novelty in the pipes having pressure reducing member in the pressure irrigation systems according to the present invention are illustrated.

The main locking mechanism (11) shown in the figure interconnects the main distribution pipes (1 ) and performs elongation process. The liquid entering in liquid flow direction (X) through the main pipe liquid inlet (12) is depressurized thanks to the novelty in the pipes having pressure reducing member in the irrigation systems according to the present invention, and is transferred to lateral pipes (9).

Figure 4 is the perspective view of water channels of the novelty in the pipes having pressure reducing member in the sprinkler and drip irrigation systems according to the present invention. Lateral pipe liquid passage channel (2.1), gasket (4), liquid channels (5), liquid channel inlet hole (5a), liquid channel outlet hole (5b) and gasket hole (5c) are illustrated in the figure.

The flow rate of the liquid received from the pipe is adjusted by means of liquid channels (5) in accordance with pressure. The liquid enters into liquid channel inlet hole (5a) and the flow rate thereof is adjusted and then, it is discharged through the liquid channel outlet hole (5b).

When the pressure arises remarkably, the gasket (4) stretches and covers the gasket hole (5c) or narrows the hole even if it does not cover it completely.

Figure 5 is the perspective view of water channels of the novelty in the pipes having pressure reducing member, preferably without gasket, in the sprinkler and drip irrigation systems according to the present invention. Lateral pipe liquid passage channel (2.1 ), liquid channels (5), liquid channel inlet hole (5a), liquid channel outlet hole (5b) and mounting hole (5d) are illustrated in the figure. The production method of said irrigation system is as follows;

- providing liquid passage channel (2.1 ) on the main passage body (2),

- fixing said main passage body (2) in the fixing gap (1.1) provided on axis x-y of main distribution pipe (1 ),

- positioning the pressure balancing member (6) in the positioning area (2.2) of the fixed main passage body (2.2),

- positioning the gasket (4) between said pressure balancing member (6) and liquid passage channel (2.1),

- fixing the intermediate connection pipe (13) in the mounting hole (5d) of said pressure balancing member (6),

- providing screwed surfaces (6.1) at the inner and outer surfaces of said pressure balancing member (6),
