Abstract
The utility model discloses a protective valve for an air pressure regulating system for a vehicle and engineering machinery, which comprises a protective valve body, an upper shell, an air inlet and air outlets, wherein the air inlet and the air outlets are arranged on the protective valve body; four air outlets are provided; air circuits of the air inlet, which are communicated to the corresponding air outlets, are provided with air inlet valves; each air inlet valve is provided with an air inlet valve seat and a diaphragm; the air circuits from the air inlet valves to the air outlets are provided with check valve assemblies; and the conduction direction of each check valve assembly is from the air inlet to the corresponding air outlet. After the technical scheme is adopted, the multiloop protective valve is arranged in the multiloop brake system of the vehicle or an engineering vehicle. The protective valve is more beneficial for better protecting the safety air pressure in the brake system. When one loop loses effectiveness, certain safety brake air pressures in other loops can still be ensured, so that the safety using performance of the whole vehicle is improved. The protective valve has the effects of automatically regulating and safely protecting the pressure of the system.
