Air flow on-off valve
This invention belongs to the field of pneumatic control valve technology, specifically providing a pneumatic shut-off valve. The invention aims to solve the problem of excessive noise during operation of existing pneumatic shut-off valves. To this end, the pneumatic shut-off valve of this invention includes a valve body assembly, a valve core assembly, and a sealing ring. This invention defines a distal variable volume cavity and a proximal variable volume cavity located on opposite sides of the axial direction of the movable yoke by having the valve core assembly and the valve body assembly jointly define such cavities. When the valve core assembly moves in one direction along its axial direction, the sealing ring first blocks the annular channel and then opens it. In this way, the initial movement of the valve core assembly is hindered by the air pressure difference, reducing its moment of inertia and speed, thereby weakening the impact force of the valve core assembly on the valve body assembly and reducing the noise during operation of the pneumatic shut-off valve.
