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 applies 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 stainless steel (or cobalt-chromium-tungsten alloy) inlaid or surfacing on the sealing surface, which has a double seal of metal and metal to metal, and the sealing surface can remove the dirt of the gate at the same time.
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, is always consistent with the sealing surface, and the sealing surface is protected from direct erosion by the medium, thereby prolonging the service life.
5. When the slab gate valve is fully opened, the passage is smooth and straight, the flow resistance coefficient is very small, and there is no pressure loss. The pipeline can be cleaned by 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 has 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 flat gate valve is closed, the high pressure in the 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.
