Sewage valve structure principle

The structure principle of the blowdown valve <br>Fast is directly dependent on the force generated by the medium pressure to help the mechanical charge seal acting on the valve flap. The mechanical load acting on the blowdown valve flap is mainly from the compression spring, which is almost fixed. Mechanical load. Although for compression springs, the load can be adjusted to achieve a good seal by adjusting the spring force, the seal pressure differential must be strong enough to ensure adequate sealing force to achieve a seal when the drain valve is operating normally. The seal pressure difference should also be less than the opening and closing pressure difference to ensure flexible opening.
