The use features
The gate valve adopts new type of floating ring seal structure, is applicable to pressure is not greater than 15.0 MPa, allow to temperature - 29 ~ 121 ℃ of the oil and gas pipeline, as control opening and closing of the medium and adjusting device, the product structure design, material selection, strict testing, convenient operation, appropriate with strong corrosion, wear resistance, erosion resistance, is a kind of ideal new oil industry equipment.
Flat gate valve structure characteristics and working principle
1. The floating seat, two-way opening and closing, reliable seal, flexible opening and closing. Article 2. The disc are oriented to give precise guidance, at the same time, sealing surface spraying weld hard alloy, resistance to erosion. 3. The body carrying capacity is high, the channel for straight-through, fully open, similar to phase penetration and straight pipe ram flow guide hole, small flow resistance. Stem with composite packing, multiple seal, make reliable sealing, low friction. 4. Close the self-reliance type valve, rotating the handwheel clockwise, ram down to the bottom, due to the effect of medium pressure, inlet side seal seat to ram direction, form a larger sealing pressure, thus forming the first seal. At the same time, the ram pressure toward the outlet seal seat, become a double seal. 5. As a result of double seal, so can work without affecting pipeline under the condition of replacement parts. This is our factory product prior to the important characteristics of similar products at home and abroad.
3, butterfly plate sealing surface using cobalt-based carbide surfacing, sealing surface wear resistance, long service life
4, large size butterfly plate adopts the structure supporting structure, high strength, large flow area, small flow resistance
5, hard seal butterfly valve has two-way sealing function, installation is not restricted by medium flow direction, and is not affected by spatial location, can be installed in any direction
6, driving device can transfer (rotate 90 ° or 180 °) installation, making it easy for users to use
