Check valves are generally divided into lift, swing and other several types.
Lift check valve general similar to cut-off valve, the structure of the disc along the center line of the channel for lifting movement, reliable action, but the fluid resistance is bigger, is suitable for the occasion of a small diameter. Lift check valve can be divided into straight-through and vertical two kinds. Straight-through lift check valve generally can only be installed in a horizontal pipe, and the vertical lift check valve should be installed in a vertical pipe commonly.
Swing check valve disc around the axis of rotation. The fluid resistance is generally less than lift check valve, it is suitable for large caliber of occasions. Swing check valve according to the number of the disc can be divided into single swing, more than double disc swing and swing three segments. Single swing check valves are generally applicable to medium caliber. Large diameter single swing check valve is used in the pipeline, to reduce the water hammer pressure, had better use can reduce the water hammer pressure slowly-closing check valve. Double disc swing check valve .
The difference between power station check valves and other valves:
1. The product design and manufacture according to standard E101 and JB/T3595-93 rules, reasonable structure, excellent performance, modelling.
2. The valve lumen self-tightening seal structure is adopted, and the medium pressure is higher, the sealing performance, the better.
(3) for butt welding on both ends of the branch pipe, different to meet the demand of the takeover.
4. The disc and seat sealing surface using department too vertical (stellite) cobalt-based hard alloy surfacing and become, wear-resisting, high temperature resistance, good abrasion resistance, long service life.
5. Made of high quality alloy steel manufacturing, safe and reliable, stable performance, especially suitable for high temperature and high pressure pipeline.
