9000 piston water hammer absorbing device
introduction
8000 Diaphragm balloon type water hammer absorbing device is composed by shell, inner balloon (advanced diaphragm rubber) and pore tubes and so on. It is applied to industrial and mining enterprises, high-rise buildings, power plants and other types of water supply and drainage system. 8000 Diaphragm balloon type water hammer absorbing device has a remarkable ability to absorb water hammer without preventing water flow conditions, effectively absorb the water hammer.
The internal part of 9000 piston water hammer absorbing device is enclosed gas chamber, the lower end is a piston. When the impact waves income EN-9000 piston water hammer absorbing device, the water shock wave acts on the piston, the piston will move to the direction of air chamber, the piston moves up and down in a certain pressure gas and dual effects of irregular waves under the water hammer, to form a dynamic equilibrium, thus eliminating the irregular water hammer shock waves.
