Abstract
The invention discloses a pipe connection exhaust valve. The bottom of a valve body of the exhaust valve is provided with an air inlet hole. The upper portion of the valve body is provided with an exhaust hole. A valve ball is arranged in an inner cavity of the valve body. An exhaust channel communicated with the exhaust hole is arranged above the valve ball in the inner cavity of the valve body. The valve ball is a soft valve ball. The front end of the exhaust channel is a conical channel, wherein the soft valve ball is directly matched with the inner wall of the conical channel to seal the exhaust channel. According to the pipe connection exhaust valve, due to the fact that the soft valve ball is arranged in the inner cavity of the valve body and makes direct contact with the inner wall of the conical channel at the front end of the exhaust channel for sealing, an original seal ring is omitted, the sealing effect is good, and the service life of the exhaust valve is prolonged; meanwhile, the exhaust valve is light in overall structure, easy to manufacture, low in cost and capable of being formed through a mold.
Description
Technical field
The application belongs to outlet valve, is specifically related to a kind of pipeline on the irrigating facilities such as infiltrating irrigation, drip irrigation, micro-spray and connects outlet valve.
Background technique
At present, for infiltrating irrigation, drip irrigation, the effect of the outlet valve on the irrigating facilities such as micro-spray is discharged from pipeline by the air in irrigation pipeline, unimpeded to ensure the current in pipeline, avoid pipeline internal cause air stagnation and blockage phenomenon, existing outlet valve is that the valve body be made of metal is formed, valve body is an entirety, body cavity has a valve ball firmly processed, the internal chamber wall on valve body top is provided with a seal ring, body cavity is placed one and to be coordinated with valve ball and the support ring supporting valve ball, gas discharge vent is formed between support ring and body cavity wall, the top cloth of valve body is closed shape, valve body top has exhaust port, body base is provided with inlet hole, outlet valve accesses irrigation pipeline by the connecting tube connected with inlet hole, when pipeline has water, valve ball is held up by inlet hole by water, and valve ball disengaging support ring is moved up, until valve ball withstands seal ring and makes exhaust valve closure, when there being air in pipeline, valve ball departs from seal ring according to gravity and moves down, and stop dropping on support ring, air enters body cavity by inlet hole through the exhaust hole between support ring and body cavity wall, discharged by the exhaust port on valve body top again, this kind of exhaust structure heaviness, complex manufacturing technology, cost is high, the seal ring matched with hard valve ball arranged due to body cavity is very easily aging, sealing effect is poor, shorten the working life of outlet valve.
Summary of the invention
The object of the application is to provide that a kind of light structure, preparation process are simple, cost is low, the pipeline of good sealing effect connects outlet valve.
The application is achieved in that pipeline connects outlet valve, the bottom of its valve body is provided with inlet hole, and the top of valve body is provided with exhaust port, and the inner chamber of valve body is provided with valve ball, be provided with the exhaust passage be connected with exhaust port above the valve ball of body cavity, 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.
Body cavity wall below described soft valve ball can have one to go in ring step, this belt step is provided with some and soft valve ball and matches the support platform merging and support soft valve ball, leaves exhaust breach between 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 simplified inner chamber, and described exhaust passage is positioned at lid, and described exhaust elbow is positioned on lid.
The application is soft valve ball because body cavity is provided with, this soft valve ball directly and the contact internal walls of the tapered channel of front end, exhaust passage seal, eliminate original seal ring, good sealing effect, extend the working life of outlet valve, also make the overall structure of outlet valve light and handy simultaneously, make simple, cost is low, available mould-forming.
Accompanying drawing explanation
Below in conjunction with embodiment, the application is described in detail:
Figure l is the structural representation of the application's outlet valve.
Pipeline connects outlet valve, its valve body can adopt 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, be provided with the exhaust passage 5 be connected with exhaust port 2 above the soft valve ball 4 of body cavity 3, 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.Body cavity wall below described soft valve ball 4 there is a belt step 7, this belt step 7 is provided with some and soft valve ball 4 and matches the support platform 8 merging and support soft valve ball 4, exhaust breach 9 is left between adjacent supports platform 8, another kind of mode of execution establishes a hollow circular-tube bottom inner chamber 3, this hollow circular-tube supports soft valve ball 4, and the tube wall of hollow circular-tube offers some pores.
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 effectively prevent external impurities from entering outlet valve.Lid can be divided into again upper cover body 11 and dust-proof lid 12, exhaust port 2 is positioned at the bottom of the dust-proof lid 12 shown in figure l, directly serve dust-proof effect, dust-proof lid 12 is sealed in upper cover body 11, soft valve ball 4 is positioned at the inner chamber of simplified 10, described exhaust passage 5 is positioned at upper cover body 11, and upper cover body 11 is provided with pore 13 equally, and described upper cover body 1l is threaded with cylindrical shell 10.
Claims (5)
