- Q:To prevent water meter rotation, where should the check valve be installed?
- Do not pack more than 35 of the weak currentChasing the answerShould be installed at the outlet of the water meter (that is, water to the other side of the room)
- Q:Can the check valve be horizontally installed?
- Lift check valve can be divided into straight through and vertical two. Straight through lift check valve can only be installed in horizontal pipe, vertical lift check valve is usually installed in vertical pipe.
- Q:Is it necessary to install a check valve for suction well pumping well? If you need to install what kind of check valve (about lifting, butterfly valve, also a what to forget), which (installed in the water outlet, water inlet, or water pipe), ask again need to install the filter valve? I do not understand, ask for expert doubts! Thank you very much!
- The filter screen is arranged at the water inlet check valve and is installed below the water pump
- Q:Check valve does not automatically check back, how to adjust?
- 4 the vertical lift check valve shall be mounted on a vertical pipe.5, the lift type horizontal check valve shall be installed on the horizontal pipe.6. Do not check the weight of the valve in the line. The large check valve shall be independently supported so as not to be affected by the pressure caused by the piping system.
- Q:What's the difference between a throttle valve and a check valve? Are they the same?
- The check valve is directional, so it should be clear when installing. It is like a swinging door that opens in one direction or closes on the other. When the liquid flows towards the opening, the door opens, and when it is stopped, the self pressure of the liquid passing through the door closes automatically and acts as a hindrance to the flow of liquid.Throttle is simple, water switch is one of the throttle valve.
- Q:How can the fast closing noise check valve prevent water hammer?
- Biaoguan valve that once the pump stopped, check valve spool in the spring or other auxiliary device for double end under the action of force balance in advance to the closed position, can greatly reduce the amount of water and initial water reflux falling height, water hammer force is calculated by gravity superposition, to reduce the amount of water is equal to the reduced gravity, but fell short height reduces the inertia time is relatively reduced speed, and can prevent the formation of destructive or reduce water hammer water hammer.
- Q:Does the regulator have a check action? If yes, can I use it as a check valve?
- There are some regulators that have this reverse cut-off. A regulator without overflow. Such as gas regulator.For example, the compressed air regulator has no reverse cut-off function.Regulators in the form of a lot of specific circumstances, specific analysis, only to exceed the body can withstand the pressure, generally not bad.
- Q:What does the check valve "h61h-25 H" mean?
- From the model analysis, for the cast steel welding lift check valve, it depends on your valve is not it
- Q:What are the features of axial check valves?
- Axial flow check valve (GB/T 21387-2008) by the standardization of the national valve technical committee (SAC/TC 188). The drafting unit: Shanghai Huatong Valve Co., Ltd., Ningbo aimeike copper valve valve Co. Ltd. Shanghai zhengfeng. Main drafters: Zhang Yonghui, Liu Tienan, Zheng Xuezhen, Chen Tiewang, Meng Aimin.

- Q:Ask questions about the installation of check valves after water meters
- Generally installed after the water meter. The main reason: if the water point is higher than the water meter installation position, once the pipe network in the absence of water, the remaining water in the pipeline will flow in the direction of the water meter in turn. This will cause the water meter to reverse and cause damage to the water meter. A check valve is installed after the water meter, so that the situation can be avoided.
