活塞式水锤吸纳器 概述 ： I. Overview of piston water hammer absorber :
活塞式水锤吸纳器 YQ9000 piston water hammer absorber The utility model is a hydraulic protection device for buffering the water hammer by sealing the air pressure cavity to eliminate the water hammer shock wave caused by various reasons in the pipeline, and preventing the water supply pipes and facilities of the building from being damaged by the water hammer. Applicable to various water supply and drainage systems such as industrial and mining, enterprises, high-rise buildings, power stations, etc. The use of air expansion and contraction in the chamber above the piston can buffer the sudden shock wave and alleviate the intensity, and avoid the huge water hammer Damage to equipment caused by impulse. The device has a simple structure, excellent materials selection and long service life.
活塞式水锤吸纳器 工作原理 Working principle of piston water hammer absorber
活塞式水锤吸纳器 内部有一密闭的容气腔，下端为一活塞，当冲击波传入水锤消除器时，水击波作用于活塞上，活塞将往容气腔方向运动。 Inside the YQ9000 piston water hammer absorber is a closed air chamber with a piston at the lower end. When the shock wave is transmitted to the water hammer eliminator, the water shock wave acts on the piston and the piston will move toward the air chamber. The stroke of the piston's movement is related to the gas pressure in the air chamber and the size of the water shock wave. Under the dual action of a certain pressure of gas and irregular water hammer, the piston moves up and down to form a dynamic balance, which effectively eliminates Irregular water waves oscillate.
活塞式水锤吸纳器 特点 Third, the characteristics of the piston water hammer absorber
活塞式水锤吸纳器 能在无需阻止流体流动的情况下，有效地消除各类流体在传输系统可能产生的水外锤和浪涌发生的不规则水击波震荡，从而达到消除具有破坏性的冲击波，起到保护之目的。 The YQ9000 piston water hammer absorber can effectively eliminate the irregular water shock wave vibration caused by the external water hammer and surge of various fluids in the transmission system without blocking the flow of the fluid, thereby eliminating the destructive Shock wave for protection purposes. YQ98002 filter piston type safety pressure relief valve , closes smoothly and reliably, and eliminates pressure residual waves.

活塞式水锤吸纳器 安装示意图及 注意事项： Installation diagram and precautions of piston water hammer absorber :
、阀体上的压力表，安装前显示阀体气室压力，安装后显示管道压力。 1. The pressure gauge on the valve body shows the pressure of the valve body air chamber before installation and the pressure of the pipeline after installation.
、安装前请确认，水锤消除器气室压力不得高于管道压力 2. Please confirm before installation that the pressure of the air hammer of the water hammer eliminator must not be higher than the pressure of the pipeline
、当扬程 50m 以上，压力 5Kgf/cm 2 以上时，建议长道管下方及逆止阀止阀上方转角处各安装一只水锤消除器。 3. When the head is more than 50m and the pressure is 5Kgf / cm 2 or more, it is recommended to install a water hammer eliminator below the long tube and at the corner of the check valve.
、为考虑维修，建议保留 10cm 阀体与墙面间隙，方便维修动作。 4. For consideration of maintenance, it is recommended to keep a gap of 10cm between the valve body and the wall to facilitate maintenance operations.
、若管道内水压力较低，或水锤消除器气室压力较低，皆可帖水锤消除器上方注气栓加入气压或释放气压。 5. If the water pressure in the pipeline is low, or the pressure of the water hammer eliminator air chamber is low, you can add air pressure to the air injection plug above the water hammer eliminator or release the air pressure.
、水锤消除器气室压力，维持于管道压力 50%~70% 时水锤消除器效果最佳 6. The air hammer pressure of the water hammer eliminator. The water hammer eliminator works best when it is maintained at 50% ~ 70% of the pipeline pressure .
、二次侧为开放压力场合，例定水位阀，卫浴器具，水龙头等注气 1-1.3Kgf/cm 2 较适合 . 7 , the secondary side is open pressure occasions, such as water level valves, sanitary appliances, faucets and other gas injection 1-1.3Kgf / cm 2 is more suitable .
