The flat gate valve can be divided into a manual flat gate valve, a pneumatic flat gate valve and an electric flat gate valve according to the driving mode. According to the use and use occasions, it can be divided into sluice gate valve with diversion hole, flat gate valve without diversion hole, oil plate flat gate valve, pipeline flat gate valve and gas flat gate valve.
Flat gate valve structure
1. When closing the valve, turn the handwheel clockwise and move the ram down to the bottom. Due to the pressure of the medium, push the inlet end seal seat toward the ram direction to form a larger sealing pressure, thus forming the first seal. . At the same time, the shutter is pressed against the outlet end seal seat to form a double seal.
2. Due to the double seal, the consumables can be replaced without affecting the work of the pipeline. This is an important feature of our products in preference to similar products at home and abroad.
3. When the gate is opened, turn the handwheel counterclockwise, move the gate, and the guide hole will penetrate with the passage hole. As the gate rises, the through hole gradually increases. When the limit position is reached, the flow guiding hole and the channel hole coincide with each other, and are fully opened at this time.
