Abstract
The invention discloses a hand-control brake valve, comprising a valve body and a mandrel extending into the valve body, wherein an air inlet valve seat is arranged at the side part of the valve body, an air exhaust valve seat is arranged at the bottom of the valve body, a mandrel seal ring is sleeved outside the upper part of the mandrel, a spring is connected between an intermediate-section step of the mandrel and an intermediate-section step on a cavity wall of a through cavity of the valve body, and a rubber valve capable of plugging a step part of the through cavity of the valve body is arranged at the bottom end of the mandrel. The hand-control brake valve disclosed by the invention has the advantages of simple structure, easiness for realization, simplicity, feasibility, convenience for use, and increased working efficiency.
Description
Technical field
The present invention relates to the auto parts machinery field, be specially a kind of hand braking valve.
Background technique
Hand braking valve is the vitals in the automobile gas circuit braking system, and its effect is the break-make that makes gas circuit in the manual Control of Automobile gas circuit of the driver braking system.Existing technology hand braking valve complex structure, the driver operates inconvenience, can not make the timely break-make of gas circuit in the gas circuit braking system, causes running unstable.
Summary of the invention
The object of the invention provides a kind of hand braking valve, to solve the unhandy problem of existing technology hand braking valve.
In order to achieve the above object, the technological scheme that the present invention adopted is:
Hand braking valve comprises the valve body with vertical step-like cavity, and said valve body cavity chamber wall intermediate section forms step; The valve body sidepiece is equipped with inlet valve seat; Have the air inlet through hole that is communicated with valve body cavity and valve body outside in the inlet valve seat, the valve body bottom is equipped with delivery valve seat, has in the delivery valve seat to be communicated with valve body cavity and the outside exhaust hole of valve body; It is characterized in that: also include from the valve body top and stretch into the mandrel the valve body; Be with the stem seal circle that constitutes sealing with valve interior wall outside the said mandrel top, said mandrel intermediate section forms step, is connected with between mandrel intermediate section step and the valve body cavity chamber wall intermediate section step to be enclosed within the outer spring of mandrel; Valve body cavity stepped part is passed in said mandrel bottom, and the mandrel bottom is equipped with the rubber valve that can stop up valve body cavity stepped part.
Described hand braking valve is characterized in that: be provided with packing ring between said delivery valve seat and the junction, valve body bottom.
The present invention is simple in structure, is easy to realize, drives the rubber valve action through mandrel during use; To stop up valve body cavity stepped part or to break away from from valve body cavity stepped part, the realization suction port is communicated with or disconnection with relief opening, and is simple; Easy to use, the outer spring upper end of mandrel is connected on the mandrel step simultaneously, and the spring lower end is connected on the cavity step; Can realize effectively that mandrel resets, and has improved the working efficiency of hand braking valve.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
As shown in Figure 1.Hand braking valve comprises the valve body 1 with vertical step-like cavity, and valve body 1 cavity chamber wall intermediate section forms step; Valve body 1 sidepiece is equipped with inlet valve seat 2; Have the air inlet through hole 3 that is communicated with valve body 1 cavity and valve body 1 outside in the inlet valve seat 2, valve body 1 bottom is equipped with delivery valve seat 4, has the exhaust hole 5 that is communicated with valve body 1 cavity and valve body 1 outside in the delivery valve seat 4; Also include from valve body 1 top and stretch into the mandrel 6 the valve body 1; Be with the stem seal circle 7 that constitutes sealing with valve body 1 inwall outside mandrel 6 tops, mandrel 6 intermediate sections form step, are connected with the spring 8 that is enclosed within outside the mandrel 6 between mandrel 6 intermediate section steps and the valve body 1 cavity chamber wall intermediate section step; Valve body 1 cavity stepped part is passed in mandrel 6 bottoms, and mandrel 6 bottoms are equipped with the rubber valve 9 that can stop up valve body 1 cavity stepped part.Be provided with packing ring 10 between delivery valve seat 4 and the junction, valve body 1 bottom.
