A pneumatic water hammer arrestor valve, also known as an airbag type water hammer absorber valve, is a device used to prevent water hammer in plumbing systems. Water hammer occurs when the flow of water is suddenly stopped or changed in a plumbing system, resulting in a loud banging noise and potentially damaging the pipes.
The pneumatic water hammer arrestor valve works by using an airbag or air chamber to absorb the shock waves created by the sudden change in water flow. When the water flow is suddenly stopped or changed, the air in the airbag compresses, absorbing the shock and preventing it from traveling through the pipes.
Product description:
ZYA-8000 type rubber bladder airbag type water hammer absorber is composed of an inner shell, a high-grade synthetic rubber liner and a porous tube. It is suitable for all kinds of water supply and drainage pump systems in industries, mines, enterprises, high-rise buildings, power stations, etc. Under the condition of not needing to stop the water flow, it has excellent water shock absorption and effectively absorbs water hammer.
ZYA-9000 piston type airbag water hammer absorber has a closed air chamber inside, and the lower end is a piston. When the shock wave enters the water hammer absorber, the water shock wave acts on the piston, and the piston will move towards the air chamber, and the piston moves up and down under the double action of the gas under a certain pressure and the irregular water shock wave, forming a dynamic Balanced, thus eliminating irregular water shock waves.
