• First, check valve introduction

  A check valve, also known as a return valve, is a valve that allows fluid to flow in only one direction. This valve has a wide range of applications in a variety of industrial equipment and systems, especially where there is a need to prevent fluid backflow or maintain system pressure. A check valve is usually composed of a body, a spool and a spring.

  Two, the working principle of the check valve

  1. Forward flow: When the fluid flows in from the inlet, the fluid pressure acts on the spool, overcomes the spring resistance, moves the spool to the outlet, opens the valve, and allows the fluid to pass. At this point, the valve is open due to fluid pressure.
  2. Reverse flow: When the fluid flows in reverse, the fluid pressure acts on the spool, but at this time due to the resistance of the spring, the spool can not move to the outlet end, thus closing the valve and preventing the fluid from passing. At this time, due to the resistance of the spring, the valve is closed
