Swing check valve

swing check valve
The applicable medium of the swing check valve is water, oil, steam, etc. The middle cavity of the power station check valve adopts a pressure self-tightening sealing structure. The higher the inner cavity pressure, the better the sealing performance. Both ends of the branch pipe are butt welded to adapt to different pipe connection requirements.
2. Product Structural Features Swing Check Valve
The product is designed and manufactured according to standards and can be used with imported equipment.
The door cavity adopts a pressure self-tightening sealing structure. The higher the pressure in the inner cavity, the better the sealing performance. The two ends of the branch pipe are butt welded to adapt to different pipe connection requirements.
The pressure-resistant parts of the door are made of high-quality heat-resistant alloy steel, which has good high-temperature performance, high pressure resistance, durability, safety and reliability.
The sealing surface of the flap valve seat is made of Stellite cobalt-based hard alloy surfacing, which is wear-resistant and high-temperature resistant, has good scratch resistance and has a long service life.
The flap rotates around the pin outside the valve seat to reduce violent impact when closing.
The installed pin structure reduces external leakage points and is more reliable in use.
