Fluorine lined gate valve is a kind of valve. Fluorine gate valve opening and closing member is the gate, gate movement direction perpendicular to the direction of the fluid, gate valve can only be fully open and fully closed, can not be used for regulation and throttling. Gate has two sealing surfaces, the most commonly used mode gate valve two sealing surfaces to form a wedge, wedge angle varies with the valve parameters, the media temperature is not high for 2 ° 52 & # 39;. Wedge gate valve gate can be made into a whole, called the rigid gate; can also be made to produce a small amount of deformation of the gate, in order to improve its craftsmanship, to make up for the angle of the sealing surface in the processing of deviation, this gate is called the elastic gate.

1. Gate valve opening and closing member is the gate, the movement direction of the gate is perpendicular to the direction of the fluid, the gate valve can only be fully open and fully closed, can not be used for regulating and throttling. 2. gate valve gate with the stem together for linear movement, called the lifting stem gate valve (also called open stem gate valve). Usually in the lifting rod on the trapezoidal thread, through the valve end of the nut and the valve body on the guide groove, the rotary movement into a straight 3 line movement, that is, the operating torque into the operating thrust.

Soft seal gate valve opening and closing member is the gate, the movement direction of the gate is perpendicular to the direction of the fluid, the gate valve can only be fully open and fully closed, can not be adjusted and throttling.

Soft seal gate valve opening and closing member is the gate, the movement direction of the gate is perpendicular to the direction of the fluid, the gate valve can only be fully open and fully closed, can not be adjusted and throttling.
