Structural Characteristics and Working Principle of High Pressure Flat Gate Valve

Apr 03, 2023

1. Adopt floating valve seat, two-way opening and closing, reliable sealing, and flexible opening and closing.

2. The lower part of the gate is provided with a diversion hole, which is accurately guided. The seal is also sprayed with welded hard alloy to resist corrosion.

3. The valve body has a high bearing capacity and a straight passage. When fully open, the connection to the gate diversion hole is similar to a straight pipe, and the flow resistance is very small. The valve rod adopts composite packing and multiple seals, ensuring reliable sealing and low friction.

4. Close the valve and turn the handwheel clockwise to lower the gate to the bottom. Due to the mass pressure at the interface, the sealing seat at the inlet end is pushed towards the gate. Forming a larger sealing pressure, thereby forming a seal. At the same time, press the pressure head on the sealing seat facing the outlet end, which becomes a double seal.

5. Due to the use of dual seals, it is possible to replace worn parts without affecting pipe work. This is an important characteristic of our factory's products that are superior to those of our peers at home and abroad.

"When opening the shutter, rotate the handwheel counterclockwise, and the shutter moves upward. The flow guide hole and the flow guide slot hole are connected.". As the gate rises, the through-hole gradually becomes larger. When it reaches a certain position, the diversion hole coincides with the passageway hole, which is now fully open.
