Along with the quickening of The development in society and economy and people's rhythm of life, automobile obtains application more and more widely in daily life and work.The automobile levelling valve is used to be equipped with the automobile of air suspension; Be that to regulate air bag air pressure according to car load be the control cock of a steady state value to keep bodywork height; The balance that keeps vehicle in helping running at high speed with can be handling; Help improving the damping property of vehicle and, reduce the destruction of vehicle road pavement, stability and the reliability that improves vehicle played important effect goods in the vehicle or passenger's protection.The shortcoming of traditional levelling valve is that structure is comparatively complicated, the fitting operation trouble, and poor sealing performance and valve rod easy abrasion cause compressed-air actuated waste simultaneously easily.
In order to solve the problem that prior art exists, people have carried out long-term exploration, have proposed multi-form solution.For example, the Chinese patent document discloses a kind of automobile levelling valve assembly [application number: 200520101314.7], comprises levelling valve and control cock; Levelling valve is provided with admission port, air extractor duct, exhausr port and control mouth, is provided with valve pocket and spring perch in levelling valve inside, and valve pocket is provided with valve rod; Be installed with the end on the valve rod and be located at the spring on spring perch and the valve pocket; Lean on admission port end end to be provided with valve at valve rod, be provided with valve spring between valve and the admission port, be provided with the piston of band O RunddichtringO between valve and the spring perch; The other end at valve rod is provided with set screw and is with the dust boot of filtering hair, in the control mouth of levelling valve, is provided with valve pocket to be connected but unfixed rotating shaft.
Such scheme has improved prior art to a certain extent, makes the structure of levelling valve comparatively simplify, and the sealing property of levelling valve is also improved to some extent.But still there are technical matterss such as fitting operation is inconvenient, sealing effectiveness is general, valve rod easy abrasion in this scheme.
Summary of the invention
The purpose of the utility model is to the problems referred to above, provides a kind of reasonable in design, simple in structure, and equipment cost is low, uses easy to operately, and good seal performance can reduce the levelling valve of stem wear.
For achieving the above object; The utility model has adopted following technical proposal: this levelling valve, and the valve body of the side's of comprising shape is provided with valve rod on valve body; Described valve rod is connected with valve body through rotating shaft; Side at valve body is provided with the control mouth, on valve body, is respectively equipped with admission port and air extractor duct with control mouthful vertical both sides, in valve body, is provided with the control mechanism that can control admission port and air extractor duct switching.
In above-mentioned levelling valve, described control mechanism comprises piston and the piston rod that is located in the valve body, and described piston rod is connected with transmission device.
As a kind of technical scheme of comparatively optimizing, in above-mentioned levelling valve, described transmission device comprises the slide that is located in the valve body, on slide, is connected with slide block, and described slide block is connected with piston rod.
Further, in above-mentioned levelling valve, be equipped with seal ring on described control mouth, admission port and the air extractor duct.
In above-mentioned levelling valve, between valve rod and valve body, be provided with square baffle plate, described square baffle plate is equipped with connecting bore for four jiaos.
Compared with prior art, the advantage of this levelling valve is: reasonable in design, simple in structure, equipment cost is low, uses easy to operately, and good seal performance simultaneously can reduce stem wear.
