Smolensky Check Valves

The smolensky check valves is the lift check valves added by pass. It can make a function of harmless check valves, dashpot check valves.

• Water Hammer!-The Enemy of  Flow Pipeline

The water hammer occurs by sudden flow stopping caused by pump-off or pressure wave caused from the pipes bending.

• Smolensky check valves----No Impact , No Dining.

This commodity is the superb check valves designed to prevent the water impact with the operation of buffer hill&spring inside, thereby the water hammer&breakage of the pipes can be protected.

• Theory of Operation

When the pump starts, the pressure of the fluid pushes disc(2)then the fluid flows to chamber (c) through the chamber (A) &(B). When the pump stops, momentarily the pressure in the pipeline falls down then the short stagnation of the flow occurs and the reverse flow follows soonest. But at the same time by the action of spring(1)&buffer hill (4)disc(2) adheres to body seat(3)therefore any reverse flow&water hammer can be prevented.

• Advantage

- No water hammer
- No trouble by the simple structure

- When the repair or replacement of the pipe is done, the water in the body champer is drained by the attached by-pass valves.
- No impact &noise
- Scrupulous &safe check
- No leakage
- Available for the vertical and horizontal piping connection
