Description
Technical field
The utility model relates to a kind of brake valve of car, especially relates to a kind of trailer braking valve.
Background technology
Brake valve of car is the control center of brake system of car middle rolling car braking, and its work quality has a direct impact deceleration and stopping performance.But the shortcoming of the trailer braking valve that uses is that the guidance quality and the resistance to abrasion of the control plunger in the valve are relatively poor at present, so influence the leak tightness of its assembly, also influences the service life of brake activation valve.
Summary of the invention
The purpose of this utility model is at above-mentioned shortcoming, provides a kind of and can strengthen the guidance quality of piston motion and the trailer braking valve of resistance to abrasion.
For achieving the above object, the utility model has mainly adopted following technical scheme.
The utility model mainly is made up of the braking valve body, valve body is combined by upper shell, middle shell and lower house, in upper shell, be provided with control plunger, control plunger is provided with groove, be placed with guide ring in the groove, the valve that is provided with piston and combines with it in middle shell also is provided with air extractor duct and admission port on middle shell, be provided with lower valve and coupled exhaust valve seat in lower house.
The utility model compared with prior art has following obvious advantage and progress.(1), the utility model increases by a groove on control plunger, put a guide ring, guidance quality when having increased piston motion and resistance to wear, and improved the leak tightness of assembly.(2), the utlity model has when the trailer brake system pilot piping and connect the function that fracture or gas leakage can cause trailer braking protection valve automatically.(3), the use of guide ring, the service life of having improved product greatly.
The utility model is loaded on the tractor truck in order to the braking of control trailer or superimposed trailer, is applicable to that trailer is a dual-line braking system, and the tractor truck main brake is a double-circuit system, stops or emergency braking is the automobile of formula braking of dying.
Below in conjunction with drawings and Examples the utility model is described in further detail.
