First, Overview
Fluorine - lined gate valve is a kind of valve. The opening and closing part of the fluorine lined gate valve is the gate plate, and the direction of the motion of the gate plate is perpendicular to the direction of the fluid. The gate valve can only be fully opened and fully closed, and cannot be adjusted and throttled. The ram has two sealing faces. The most commonly used mode gate valve has two sealing faces that form a wedge. The wedge Angle varies with the valve parameters and is 2°52' when the medium temperature is not high. The wedge gate valve can be made into a whole, called the rigid gate; It can also be made to produce a micro deformation of the ram, in order to improve its technology, make up for the Angle of the sealing surface in the process of deviation, this kind of ram is called elastic ram.
Second, product characteristics
1, the fluid resistance is small, sealing surface by media brush and erosion is small.
2, open and close less effort.
3, the medium flow is not restricted, no turbulence, no pressure reduction.
4, the shape is simple, the structure is short, the manufacturing process is good, the application range is wide.
