Main types and working principles of bidirectional flow hard impact hard rotation ball valves

1. Main Types

The main types of this valve include worm gear, electric, pneumatic, and hydraulic, among which pneumatic and hydraulic valves are suitable for situations with pressure gas sources and pressure liquid sources.

2. Working principle

The main function of a bidirectional flow valve is to seal well both under forward pressure and under reverse pressure or when the reverse pressure is greater than the forward pressure. When under positive pressure

When in operation, the medium pressure pushes the valve plate forward, causing the valve stem to deform. The sealing surface of the valve plate tightly adheres to the sealing surface of the valve seat, transmitting pressure and pushing the valve seat towards the valve body step, resulting in good sealing. When reverse pressure is applied

When in operation, the medium pressure pushes the valve plate backwards, causing the valve stem to deform. At the same time, the medium pressure pushes the valve seat backwards, and the sealing surface of the valve seat tightly adheres to the sealing surface of the valve plate to transmit pressure, ensuring good sealing.
