Abstract
The utility model relates to an irrigation exhausting valve used on irrigation facilities, such as infiltrating irrigation, drip irrigation, micro spraying, etc. An air inlet is arranged at the bottom, and an exhaust hole is arranged at the upper part. An exhaust passage is arranged above a flexible valve ball of a valve body cavity. The front end of the exhaust passage is a tapered passage for the flexible valve ball to directly match with an inner wall of the exhaust passage. An annular step is arranged on a wall of the valve body cavity. A plurality of supporting tables are arranged on the annular step. An exhaust notch is reserved between adjacent supporting tables. An original sealing ring is canceled; the service life of the irrigation exhausting valve is extended; meanwhile, the integral structure of the irrigation exhausting valve is light; manufacture is simple, and coat is low.
Description
The utility model belongs to outlet valve, is specifically related to a kind of Irrigation exhausting valve that is used on the irrigating facilities such as infiltrating irrigation, drip irrigation, little spray.
At present, be used for infiltrating irrigation, drip irrigation, the effect of the outlet valve on the irrigating facilities such as little spray is that the air in the irrigation pipeline is discharged from pipeline, unimpeded to guarantee the current in the pipeline, avoid pipeline internal cause viscous flow air and blockage phenomenon, existing outlet valve is that the valve body that is made of metal constitutes, valve body is an integral body, body cavity has a hard system valve ball, the internal chamber wall on valve body top is provided with a seal ring, body cavity is placed a support ring that cooperates and support valve ball with valve ball, constitute the exhaust port between support ring and the body cavity wall, the top cloth of valve body is closed shape, valve body top has exhaust port, the valve body bottom is provided with inlet hole, outlet valve inserts irrigation pipeline by the connecting tube that joins with inlet hole, when pipeline has water, water holds up valve ball by inlet hole, and valve ball disengaging support ring is moved up, withstand seal ring and make exhaust valve closure up to valve ball, when in the pipeline air being arranged, valve ball breaks away from seal ring according to gravity and moves down, and stop dropping on the support ring, air enters body cavity by the exhaust hole of inlet hole between support ring and body cavity wall, is discharged by the exhaust port on valve body top again, this kind exhaust structure heaviness, complex manufacturing technology, the cost height is because the seal ring that matches with the hard valve ball of body cavity setting is very easily aging, sealing effect is poor, has shortened the working life of outlet valve.
The purpose of this utility model is to provide that a kind of structure is light and handy, preparation process is simple, cost is low, the Irrigation exhausting valve of good sealing effect.
The utility model is achieved in that Irrigation exhausting valve, the bottom of its valve body is provided with inlet hole, the top of valve body is provided with exhaust port, the inner chamber of valve body is provided with valve ball, the valve ball top of body cavity is provided with the exhaust passage that is connected with exhaust port, described valve ball is soft valve ball, the front end of described exhaust passage be soft valve ball directly and its inwall match and merge the tapered channel of closes vent passage.
One step that goes in ring can be arranged on the body cavity wall of described soft valve ball below, and this belt step is provided with some and soft valve ball and matches and merge the support platform of the soft valve ball of support, leaves the exhaust breach between the adjacent supports platform.
The exhaust port on valve body top also can be connected with a reclinate exhaust elbow.
Described valve body also can be divided into lid and cylindrical shell two-part, and soft valve ball is positioned at the inner chamber of cylindrical shell, and described exhaust passage is positioned at lid, and described exhaust elbow is positioned on the lid.
The utility model is because body cavity is provided with soft valve ball, this soft valve ball directly and the inwall contact seal of the tapered channel of exhaust passage front end, cancelled original seal ring, good sealing effect, prolonged the working life of outlet valve, also made the overall structure of outlet valve light and handy simultaneously, made simple, cost is low, available mould-forming.
Below in conjunction with embodiment the utility model is described in detail:
Fig. 1 is the structural representation of the utility model outlet valve.
Irrigation exhausting valve, its valve body can adopt the plastics once-through, the bottom of valve body is provided with inlet hole 1, the top of valve body is provided with exhaust port 2, the inner chamber 3 of valve body is provided with soft valve ball 4, soft valve ball 4 tops of 0 body cavity 3 are provided with the exhaust passage 5 that is connected with exhaust port 2, the front end of described exhaust passage 5 be soft valve ball 4 directly and its inwall match and merge the tapered channel 6 of closes vent passage 5.One belt step 7 is arranged on the body cavity wall of described soft valve ball 4 belows, the step 7 that should go in ring is provided with some and soft valve ball 4 and matches and merge the support platform 8 of the soft valve ball 4 of support, leave exhaust breach 9 between the adjacent supports platform 8, another kind of mode of execution is to establish a hollow circular-tube in inner chamber 3 bottoms, this hollow circular-tube supports soft valve ball 4, offers some pores on the tube wall of hollow circular-tube.
Described valve body is divided into lid and cylindrical shell 10 two-part, and the exhaust port 2 on valve body top is as being directly arranged in the surface of lid, and this exhaust port also can be connected with a reclinate exhaust elbow, can prevent effectively that external impurities from entering outlet valve.Lid can be divided into upper cover body 11 and dustproof lid 12 again, exhaust port 2 is positioned at the bottom of dustproof lid 12 shown in Figure 1, directly played the dust-tight effect, dustproof lid 12 driving fits are on upper cover body 11, soft valve ball 4 is positioned at the inner chamber of cylindrical shell 10, described exhaust passage 5 is positioned at upper cover body 11, is provided with pore 13 on the upper cover body 11 equally, and described upper cover body 11 is threaded with cylindrical shell 10.
