1. Use

It is mainly used for water supply and drainage, and can also be used for fluid transportation in petrochemical industry. It has three functions, cut-off valve, check valve and water hammer eliminator, which can effectively improve the safety and reliability of the system, and meet the automatic control requirements of the outlet fluid of the pump when it is open and stop.

Two. Characteristics

1 when the pump is stopped, the valve can act according to the running rule of the pump automatically. No manual, electric, pneumatic and hydraulic operations are required. Manual operation is not required. It has the effect of automatic slow opening, quick closing and slow closing, and runs safely and reliably.

2 with signal identification bar, it can automatically display the operation state of the valve.

3 there is no big obstacle in the water passage, the resistance of the flow is small, and the energy saving effect is remarkable.

4 the structure is simple and reasonable, easy to install and debug, and has long service life.

Three. Technical parameters

1 nominal pressure: 1 1.6 2.5 4.0MPa

2 minimum action pressure: 0.05MPa

3 applicable temperature: 0 - 80 degrees centigrade

4 suitable medium: water, oil, chemical fluid

5 water hammer peak: less than 1.3 times the working pressure of water pump

6 slow closing time: internal adjustment in 3-120S

7 resistance loss: 30% smaller than swing check valve

8 sealing performance: working pressure is 1.1 times, duration 15S, no visible leakage.
