Flat gate valve is a member of the gate valve family, which is the same as the wedge gate valve; its main function is to control the on and off of the pipeline, not to adjust the flow of the medium in the pipeline. The advantages of the flat gate valve: small fluid resistance, labor-saving opening and closing, short structure length, no restriction on the flow direction of the pipeline medium, etc. The flat gate valve is suitable for oil, natural gas, water, oil and other pipelines with Class150～900/PN1.0～16.0MPa and working temperature of -29～121℃ to cut off or connect the medium in the pipeline.

Product structure characteristics of flat gate valve:

1. The valve seat of the flat gate valve adopts an O-ring seal and a floating seat structure that exerts a pre-tightening force to seal the inlet and outlet of the valve in both directions; and the opening and closing torque of this structure is only that of ordinary valves, which can achieve easy opening and closing. valve.

2. The valve seat of the flat gate valve adopts inlaid or surfacing stainless steel (or cobalt-chromium-tungsten alloy) on the sealing surface, which has a double seal to metal and metal to metal, and the sealing surface simultaneously removes dirt on the gate.

3. The metal-sealed valve has a grease injection structure on the outside of the valve body. The grease enters the valve sealing surface through the grease injector and the valve seat, so that the valve reaches zero leakage.

4. The gate of the valve with diversion hole, whether it is fully open or fully closed, always coincides with the sealing surface, and the sealing surface is protected from direct erosion by the medium, thereby prolonging the service life.

5. When the flat gate valve is fully open, the channel is smooth and straight, the flow resistance coefficient is very small, and there is no pressure loss, and the pipeline can be cleaned with a hair ball.

6. The flat gate valve adopts a packing structure with self-sealing capability, without frequent adjustment, is extremely light to open and close, and has reliable sealing. The stuffing box is equipped with an auxiliary sealing grease injection structure, which has reliable sealing performance and truly achieves zero leakage; solved Common valve packing is easy to leak.

7. When the plate gate valve is closed, the high pressure in the inner cavity can be automatically removed to ensure safe use.

8. Fully enclosed structure, good protection performance, can adapt to all-weather requirements.

9. The valve is equipped with an indicator rod or observation window to indicate the opening and closing of the valve.
