Gate valve is a gate with opening and closing parts. The movement direction of the gate valve is perpendicular to the flow direction. The gate valve can only be fully opened and fully closed. The parameters of the unsuitable gate vary, usually 5 ° and 2 ° 52 'when the medium temperature is not high, which improves its process ability, make up for the deviation of sealing surface angle in the process of processing. This kind of gate is called elastic gate.

Advantages of wedge gate valve:

1. The flow resistance is small. The medium channel inside the valve body is straight through, the medium flows in a straight line, and the flow resistance is small.

2. It is easy to open and close. Compared with the globe valve, whether it is open or closed, the movement direction of the gate is perpendicular to the flow direction of the medium.

3. Large height, long opening and closing time. The opening and closing stroke of the gate is large, and the gate lowering is carried out by the screw.

4. It is not easy to produce water hammer because the shutdown time is long.

5. The medium can flow in any direction on both sides and is easy to install. The gate valve channel is symmetrical on both sides.

6. The length of the structure (the distance between the two connecting ends of the shell) is small.

7. The utility model has the advantages of simple shape, short structure length, good manufacturing technology and wide application range.

8. Compact structure, good rigidity of valve, smooth passage, small flow resistance, sealing surface made of stainless steel and cemented carbide, long service life, PTFE packing, reliable sealing, light and flexible operation
