The flat gate valve is a sliding valve whose closing member is a parallel gate, and its closing member can be a single gate or a double gate with a spreading mechanism in between.
The pressing force of the gate to the valve seat is controlled by the medium pressure acting on the floating gate or the floating valve seat. If it is a flat gate valve with a double gate, the opening mechanism between the two gates can supplement this pressing force.
The flat gate valve can be divided into a manual flat gate valve, pneumatic flat gate valve, and electric flat gate valve according to the driving mode.
According to the purpose and use, it can be divided into flat gate valve with diversion hole, flat gate valve without diversion hole, oil field flat gate valve, and pipeline flat gate valve.
1. The valve seat adopts the floating valve seat structure with o-ring sealing and pre-tightening force, and the inlet and outlet of the flat gate valve are sealed in both directions; in addition, the switching torque of this structure is 1/2 of that of the ordinary valve, and the valve can be easily opened and closed.
2. When the flat gate valve is fully opened, the channel is smooth, the flow resistance coefficient is extremely small, and there is no pressure loss, and the pipeline can be cleaned with a hair ball
3. The filling material structure with self-sealing ability is adopted, which does not need to be adjusted frequently, the switch is extremely light, and the sealing performance is reliable. The auxiliary sealing grease injection structure is set at the filling material, the sealing performance is absolutely reliable, and zero leakage is truly achieved; It solves the disadvantage that the general valve packing is most likely to leak.
4. When the flat gate valve is closed, the high pressure in the inner cavity can be automatically eliminated, which is convenient to use.
5. The fully enclosed structure has good protection performance and can meet all-weather requirements.A flat gate valve operates by using a flat gate or disc to control the flow of fluids within a pipeline. Here's a step-by-step explanation of how it works:
Valve Closed Position: In the closed position, the flat gate rests perpendicular to the flow of the fluid, effectively blocking the passage of the fluid through the valve. The gate is held in place by the valve body and is in contact with the valve seats on either side to provide a tight seal.
Valve Opening: To open the valve, an operator or automated system applies force to the gate, moving it along its path of travel away from the valve seats. As the gate moves, the fluid is allowed to flow through the valve, following the open pathway created by the gate.
Fluid Flow: With the gate in the open position, fluid flows freely through the valve with minimal obstruction. The full bore design of many flat gate valves ensures that the internal diameter of the valve matches that of the pipeline, minimizing pressure drop and maximizing flow capacity.
Valve Closing: To close the valve, the gate is moved back into its perpendicular position, effectively blocking the flow of fluid through the valve. The gate returns to its closed position by the force of gravity or through the use of external mechanisms such as actuators or hand-operated mechanisms.
