New Delivery for cast steel knife gate valve PN16 factory

Short Description:

Sealing face has two gate, two of the most commonly used mode gate valve sealing surface form a wedge, the wedge Angle vary with the valve parameters, usually in the form of 50, when the medium temperature is not high for 2 ° 52 ‘. Wedge gate valve can be made into a whole, called rigid gate; It can also be made into a gate which can produce slight deformation to improve its craft and make up for the deviation of the sealing surface Angle during processing.

This type of gate is called elastic gate. Usually with trapezoidal threads on the lifting rod, the rotary motion is changed into a straight motion through the nut on the top of the valve and the guide groove on the valve body, that is, the operating torque is changed into the operating thrust. When the valve is opened, when the height of the gate is 1:1 times the size of the valve, the flow channel is fully open, but this position cannot be monitored during operation. In practical use, the valve stem is marked by the vertex, that is, the open position, as its full open position. In order to consider the temperature change in the lock phenomenon, usually open to the vertex position, and then rewind 1/2-1 turn, as the full open valve position. Therefore, the full open position of the valve is determined by the position of the gate (i.e., the stroke).
