SG9000 type water hammer elimination valve device 海茨普 production of stainless steel water hammer arrester, water hammer arrester of piston, diaphragm a water hammer arrester, absorb water hammer Features and uses: SG9000 bladder-type piston absorb water hammer inside a closed container gas chamber, the lower end of a piston. When the shock wave passed absorb water hammer, water hammer wave acting on the piston, the gas chamber to the container direction of motion of the piston of the gas under pressure and irregular water hammer wave dual role and down movement, the formation of a dynamic balance, this place eliminates the irregular water hammer shock wave. SG8000 gum gall bladder-type device to absorb water hammer from the enclosure, advanced synthetic rubber elastomer liner and perforated tubes and other components. For industrial and mining enterprises, high-rise buildings, power plants and other types of water supply and drainage system. Without the need to stop the water flow conditions, with excellent absorption of water hammer effectively absorb water hammer.
