Background

The cut-off valve is one of the executing mechanisms in the automatic system, consists of a multi-spring pneumatic membrane executing mechanism or a floating piston executing mechanism and a regulating valve, receives the signal of a regulating instrument and controls the cut-off, the connection or the switching of fluid in a process pipeline. The device has the characteristics of simple structure, sensitive response, reliable action and the like. Can be widely applied to industrial production departments such as petroleum, chemical industry, metallurgy and the like. The source of the pneumatic shut-off valve requires filtered compressed air and the media flowing through the valve body should be contaminant-free and particle-free liquids and gases. According to the allowable differential pressure condition, medium characteristics and process pipeline requirements, a single seat, a sleeve and a three-way cut-off valve can be selected.

The reliability of the operation of the shut-off valve depends to a large extent on the correct choice of the material of construction and of the material that is perfectly suitable for its operating conditions, and on the operating conditions. If the cut-off valve can only work under two states, fully open or fully closed. When the flap is in the middle position in the valve seat, a large flow velocity is generated due to a large pressure drop, which creates a cavitation condition, causing erosion, damaging the sealing surfaces of the flap and the valve seat, with the result that the tightness of the closure member is lost, and the initially small leak quickly becomes a large leak under the action of the leakage medium on the metal.
