Airbag-type water hammer absorber (also known as rubber gallbladder water hammer eliminator) is a kind of absorbing pipeline water supply system water hammer residual pressure equipment. In the water and other media transmission process, when the valve open, close, pump operation of the non-stable characteristics and radical changes, flow fusion and other reasons resulting in the pipe pressure change generation of the water hammer phenomenon often occurs, especially in high-rise buildings for common, this water hammer phenomenon in addition to produce annoying noise and vibration, serious and more will affect the entire system of action and destruction of other equipment. This valve can effectively produce high pressure wave due to water hammer, so that the pipe pressure regulation, custody of the road is not damaged. Widely used in industrial conditions, enterprises, high-rise buildings, power stations and other types of water supply and drainage systems.
Performance Characteristics
- The product features a simple structure and is easy to install and maintain.
- Stable performance and responsive operation effectively and rapidly eliminate noise and vibration in operating pipelines.
- Under all operating conditions in the pump piping system, it effectively eliminates irregular water hammer oscillations.
- High pressure resistance, capable of withstanding the impact of high-pressure water hammer.
Working Principle
Principle of the Air-Cushion Water Hammer Absorber: Under normal flow conditions, water flows through the pipeline via a perforated pipe and exits from the opposite end. When the water pressure exceeds the elastic strength of the telescopic liner and the pressure exerted by the air bladder on the liner, the telescopic liner bulges irregularly toward the air bladder. When the water pressure is lower than or equal to the air bladder pressure and the elastic strength of the telescopic liner, no bulging occurs.The water pressure within the valve body is transmitted to the telescopic liner via the perforated pipe. Due to the combined effects of the telescopic liner's elasticity and the air bladder's pressure, the telescopic liner provides rapid and effective buffering against the instantaneous pressure of water waves. This regulates the pressure within the pipe.Note: The optimal airbag inflation pressure is 70% of the working pressure. This pressure can be adjusted by inflating or deflating the nozzle valve. Tighten all bolts before installation to ensure proper equipment function. Tip: This product achieves optimal performance when installed downstream of a check valve with slow-closing or noise-reducing features.
