Abstract

The invention discloses an upper valve body whose cavity space can be compensated and adjusted and a pneumatic valve adopting the upper valve body. The upper valve body includes an upper shell, and the shell is provided with a valve core, an upper valve chamber seal, and an upper valve gasket. , upper valve spring, upper valve stopper; there is a movable piston sleeve inside the valve core, and the piston sleeve can move up and down in the upper valve core to change the air storage space inside the upper shell; the pneumatic valve also includes a lower valve body , the lower valve body is equipped with a linkage piston, a lower valve chamber seal, a lower valve gasket, a lower valve spring, and a lower valve plug; both the upper valve body and the lower valve body are connected to an independent air supply pump, and the lower valve body is also connected to the system The dynamic air chamber, through the combined action of the upper and lower valve bodies, changes the on-off of the air circuit, and then controls the airflow entering the brake air chamber to achieve vehicle braking. The invention adopts a novel valve core, which can achieve a more efficient and stable braking effect.

Description

technical field [0001] The invention relates to the field of automobile brake pneumatic valves, in particular to an upper valve body whose chamber space can be compensated and adjusted and a pneumatic valve using the upper valve body. Background technique [0002] Pneumatic valve is the main control device in the automobile service braking system. It realizes sensitive follow-up control in the braking process and release process of the dual-circuit main braking system. The brake valve is mainly composed of the upper cavity piston, the lower cavity piston, the push Rod, balance spring, return spring (upper and lower cavity), upper cavity valve, lower cavity valve, air inlet, air outlet, exhaust port, vent hole. When the driver steps on the pedal, the piston presses down the balance spring by stretching the pull rod, and the piston moves down. First, the exhaust valve is closed and the intake valve is opened. The air chamber pushes the diaphragm of the air chamber to rotate t...
