Check valve principle and internal structure
 
Check valve principle: check valves have an opening pressure, when the working medium pressure is greater than the check valve opening pressure, the spring is compressed, the check valve baffle is pushed, the medium flows smoothly. When working medium backflow, the medium will put the baffle pressure on the body of check valve, the greater the pressure of the medium, the tighter the pressure, at this time the baffle completely cut off the whole system, put an end to the possibility of media backflow, through the internal structure of the check valve can be more intuitive understanding
