Abstract
The utility model provides an exhaust valve of an irrigation pipeline. The exhaust valve comprises a valve body and a valve cover, wherein the valve body is provided with a valve body inner cavity, a valve ball is arranged in the valve body inner cavity, an air inlet hole is formed in the bottom of the valve body, the valve cover is provided with an exhaust channel, and the lower end of the exhaust channel is provided with a taper annular opening. When the exhaust valve of the irrigation pipeline is closed, the valve ball is matched with the taper annular opening to close the exhaust channel. When the irrigation pipeline works, water supports the valve ball upwards through the air inlet hole and air is exhausted. When the valve ball is attached to the taper annular opening, the exhaust valve of the irrigation pipeline is closed to prevent water leakage. When gas exists in the irrigation pipeline, the gas pushes the valve ball, and the gas in the pipeline enters the valve body inner cavity at the time through the air inlet hole and is exhausted from the exhaust channel in the valve cover. Compared with the prior art, the exhaust valve of the irrigation pipeline is good in sealing effect, simple in structure, easy to manufacture, low in cost and long in service life.

Background technique
Present existing irrigation conduit outlet valve mostly is the valve body structure that is made of metal, be provided with a seal ring at valve body top internal chamber wall, body cavity has a hard valve ball, and place a support ring that cooperates with valve ball, between valve ball inwall and support ring, consist of the exhaust port, the top is closed shape, valve body top is provided with exhaust port, the bottom is provided with suction port, the irrigation conduit outlet valve links to each other with the irrigation conduit connecting tube, when pipeline is worked, water moves up the valve ball picking-up by suction port and gas is discharged, and makes the irrigation conduit exhaust valve closure until valve ball withstands seal ring, and valve ball moves down according to gravity disengaging seal ring and stops dropping on the support ring when pipeline has gas, this moment, gas in pipelines entered body cavity, discharged through upper discharge hole.
But such irrigation conduit exhaust structure is heavy, complex manufacturing technology, and valve ball and seal ring are very easily aging, cause sealing effect poor, and working life is short, and cost is high.
The model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of simple in structure, make easily, the irrigation conduit outlet valve of long service life.
In order to achieve the above object, the utility model by the following technical solutions: a kind of irrigation conduit outlet valve, comprise valve body and valve gap, be provided with body cavity at valve body, body cavity is placed with valve ball, valve body bottom has inlet hole; Valve gap is provided with the exhaust passage, and the lower end of described exhaust passage is provided with the taper annular opening, and during the irrigation conduit exhaust valve closure, valve ball matches with closes vent passage with the taper annular opening.
When irrigation conduit was worked, water upwards held up valve ball by suction port and gas is discharged, and the irrigation conduit exhaust valve closure prevents from leaking when the annular opening plaster of valve ball and taper closes; When irrigation conduit had gas, gas was with valve ball jack-up, and this moment, gas in pipelines entered body cavity by inlet hole, and discharge the exhaust passage on valve gap.Compared to existing technology, the irrigation conduit exhaust valve sealing that provides of the utility model is effective, simple in structure, easy to manufacture, cost is low, long service life.
Further, the diameter of described inlet hole is less than the diameter of valve ball.Valve ball relies on the upper end of inlet hole under action of gravitation like this.
Preferably, in another design proposal, the lower end of described body cavity is provided with annular screens, in the annular screens support platform is installed, and the middle part of support platform is provided with diameter less than the through hole of valve ball, and this through hole is communicated with inlet hole.By support platform valve ball is carried out support, prevent that valve ball from directly contacting with the body cavity lower end, when support platform weares and teares, can change, make the longer service life of irrigation conduit outlet valve.
Preferably, described support platform is comprised of a plurality of support blocks, and described support block distributes round through hole, has the gap between the support block.When irrigation conduit has a small amount of gas can't be with valve ball jack-up the time, gas is discharged by the gap between the support block.
Further, described valve body and valve gap are threaded connection; Perhaps described valve body is connected Bond with valve gap and connects.
Further, described valve body and irrigation conduit are threaded connection.
Preferably, described valve ball is the injection molded spheroid of flexible plastic, and when the irrigation conduit exhaust valve closure, valve ball and taper annular opening plaster close tightr like this, and sealing effect is better.
Further, described valve body and valve gap are formed by plastic injection-moulded, and overall structure is simply light and handy, and cost is low.
Description of drawings
Fig. 1 is the sectional view of a kind of irrigation conduit outlet valve of the utility model.
Embodiment
Describe the technological scheme of a kind of irrigation conduit outlet valve of the utility model in detail below in conjunction with accompanying drawing.
Referring to Fig. 1, a kind of irrigation conduit outlet valve of the utility model, comprise valve body 1 and valve gap 2, be provided with body cavity 3 at valve body 1, body cavity 3 is placed with valve ball 4, valve body 1 bottom has inlet hole 5, valve gap 2 is provided with exhaust passage 7, is in communication with the outside by relief opening 6 on the exhaust passage 7, and the lower end of described exhaust passage 7 is provided with taper annular opening 8, during the irrigation conduit exhaust valve closure, valve ball 4 matches with closes vent passage 7 with taper annular opening 8.
Further, the diameter of described inlet hole 5 is less than the diameter of valve ball 4.Valve ball 4 relies on the upper end of inlet hole 5 under action of gravitation like this.
In preferred scheme, the lower end of described body cavity 3 is provided with annular screens 9, in the annular screens 9 support platform 10 is installed, and the middle part of support platform 10 is provided with diameter less than the through hole 11 of valve ball, and this through hole 11 is communicated with inlet hole 5.Carry out support by 10 pairs of valve balls of support platform 4, prevent that valve ball 4 from directly contacting with body cavity 3 lower ends, when support platform 10 wearing and tearing, can change, make the longer service life of irrigation conduit outlet valve.
In order to prevent that irrigation conduit from having a small amount of gas atmosphere not can't be with valve ball 4 jack-up, support platform 10 is designed to be comprised of a plurality of support blocks, and distributes round through hole 11, is provided with the gap between the support block, when air pressure can't be with valve ball 4 jack-up, gas was discharged by the gap between the support block.In other embodiments, be provided with aperture at support platform 10, can reach equally the exhaust effect in described gap.
