Description
Technical field
The present invention relates to the push buttonvalve field, be specially a kind of waste-gas braking push buttonvalve.
Background technique
Push buttonvalve is an important components in the air braking system of automobile, plays the effect to the control of automobile gas circuit braking system gas circuit.In the existing technology, push buttonvalve working stability, sealing are poor, are prone to the gas circuit problem of unstable when causing the work of gas circuit braking system.
Summary of the invention
The object of the invention provides a kind of waste-gas braking push buttonvalve, to solve the problem of existing technology push buttonvalve poor work stability.
In order to achieve the above object, the technological scheme that the present invention adopted is:
The waste-gas braking push buttonvalve; Include valve body, it is characterized in that: said valve body comprises the vertical section with the three sections valve pockets in upper, middle and lower that are communicated with successively, and upper and lower traversing section; The stage casing valve pocket bore of valve body vertical section is less than upper and lower section valve pocket bore; Traversing section has the inner chamber that is communicated with valve body vertical section stage casing valve pocket on the valve body, and traversing section has the inner chamber that is communicated with valve body vertical section hypomere valve pocket under the valve body, is with nut outside the traversing section joint on said valve body vertical section and the valve body; Valve body vertical section top is covered with slidably push rod cap; Be slidingly fitted with core bar in the going up of said valve body vertical section, the stage casing valve pocket, said core bar top is fixed on the push rod cap, and core bar shaft top forms limited ring dais; Core bar is with the upper end outward and is connected that the limited ring dais upper and lower end is connected on the valve body vertical section, the spring of valve pocket junction, stage casing; In the hypomere valve pocket of said valve body vertical section blocking is installed down, said have stepped slot in the blocking down, and be the valve rod of bulb valve on being slidingly fitted with in the following blocking stepped slot; In said bulb valve and the valve body vertical section, hypomere valve pocket junction constitutes ball face sealing, said valve rod is with the upper end outward and is connected bulb valve upper and lower end and is connected down the return spring on the blocking stepped slot cell wall.
Described waste-gas braking push buttonvalve is characterized in that: said core bar bottom is with the O RunddichtringO that constitutes sealing with valve body vertical section stage casing valve pocket.
Described waste-gas braking push buttonvalve is characterized in that: the outer big O RunddichtringO that constitutes sealing with valve body vertical section hypomere valve pocket sidewall that is with in said blocking down bottom, said valve body vertical section hypomere valve pocket bottom is provided with the endoporus back-up ring of spacing big O RunddichtringO.
The present invention is simple in structure; Be easy to realize that the spring on the core bar plays reset response to core bar that the outer Returnning spring of the valve rod of bulb valve plays reset response to the bulb valve; Can keep in time resetting behind core bar and the bulb valve working; The push rod cap at valve body vertical section top cooperates the endoporus back-up ring of epimere valve pocket to play spacing fixation, and the endoporus back-up ring in the valve body vertical section hypomere valve pocket also plays spacing fixation, and three sections valve pockets that cooperate step to connect can be realized the push buttonvalve stable operation; O RunddichtringO on the core bar plays seal action jointly with the outer big O RunddichtringO of following blocking, can effectively improve the push buttonvalve overall tightness.The present invention can effectively improve the push buttonvalve working stability, has also improved automobile gas circuit braking system working stability.
