3.Flat Panel Gate Valve structure and working principle:

1) Flat Panel Gate Valve adopts floating valve seat, two-way opening and closing, reliable sealing, flexible opening and closing.
2) The Flat Panel Gate Valve has a high load-bearing capacity and a straight-through channel. When fully opened, it is similar to a straight pipe through the gate orifice, and the flow resistance is very small. The valve stem adopts composite packing and multiple seals, which makes the seal reliable and low friction.
3) When the Flat Panel Gate Valve closes the valve, turn the handwheel clockwise to move the gate down to the bottom. Due to the pressure of the medium, the seal seat at the inlet end is pushed toward the gate to form a larger seal specific pressure. The first seal. At the same time, the gate is pressed against the seal seat at the outlet end to form a double seal.
5) When the Flat Panel Gate Valve opens the gate, turn the handwheel counterclockwise to move the gate, and the diversion hole and the passage hole are connected. As the ram rises, the through hole gradually increases. When it reaches the limit position, the diversion hole and the channel hole overlap, and then it is fully opened.
