The invention discloses a protective valve for an air pressure regulating system for an automobile and engineering machinery. The protective valve comprises a protective valve body, an upper shell, and an air inlet and four air outlets formed on the protective valve body; an intake valve is arranged on each air passage from the air inlet to each air outlet; the intake valve is provided with an intake valve seat and a diaphragm; a check valve assembly is arranged on the air passage from the intake valve to each air outlet; and the communicating direction of the check valve assembly is from the air inlet to each air outlet. By the technical scheme, a multi-loop protective valve is arranged in a multi-loop brake system for the automobile or an engineering vehicle to better protect the safe air pressure in the brake system; when one loop fails, certain safe brake air pressure exists in other loops so as to improve the safe use performance of the whole vehicle; and the protective valve has the function of automatically regulating and protecting the safety of system pressure.
