Q: Can the swing check valve stand upright?: Swing check valve, vertical mount, horizontal loading can be.Ordinary lift check valves shall not be erected. Lift check valves with springs can also be mounted.

Q: Check valve can not stop water, how to solve?: Valve is broken, change one, my family is like this

Q: What is the structure of the check valve of the screw air compressor?: Work process: air pre filter, and then through the air filter and the air inlet controller into the mixing chamber and the compression screw lubricating oil, continuous linear by asymmetric rotor two, compression. The compressed oil and gas mixture enters the tank and the separation system for three levels of separation (centrifugal, self weight, and fine separation). The separated compressed air is discharged after the cooler is cooled, and a reliable pressure switch system controls the exhaust pressure. When the machine is running, the screw compressor run oil system by pressure difference automatic circulation, without pump. When starting, the minimum pressure valve is closed to ensure the minimum pressure required for the lubrication oil circulation. In addition to lubrication, the oil also acts as sealing, cooling and reducing noise. High efficiency oil and gas separator and high efficiency cooler ensure high quality compressed air.

Q: The difference between the micro and slow closing check valve and the silent check valve: Noise check valve is to rely on the flow of the media itself and automatically open and close the valve, used to prevent the media back of the valve, also known as check valve, one-way valve, noise check valve, reverse flow valve, and back pressure valve. The check valve belongs to an automatic valve, whose main function is to prevent the backflow of medium, prevent the reverse of pump and drive motor, and release the container medium. The check valve can also be used to provide a supply to the auxiliary system where the pressure may rise above the system pressure. The check valve can be mainly divided into swing check valve (rotating by gravity center) and lift check valve (moving along the axis).

Q: What is the function of the stop valve and check valve installed on the water supply pipe?: The check valve belongs to an automatic valve, whose main function is to prevent the backflow of medium, prevent the reverse of pump and drive motor, and release the container medium.

Q: Is it necessary to install a check valve in front of the water meter? Does the water company have a definite requirement?: UnnecessaryWater meter before the loss of running water, their own things, do not need customers to bearAfter the water meter is equipped with a small gate valve or a ball valve, it is convenient to repair and replace

Q: Is the hdf41x 1.6Mpa a check valve?: Backflow prevention device according to tap water supply equipment, especially drinking water pipe back to serious pollution, and effectively prevent the pollution device under the condition of a strictly limited hydraulic control assembly pipeline water only one-way flow of development, its function is to prevent backflow pipeline media in any condition, in order to avoid the purpose of backflow pollution.

Q: Exhaust hood at home, the wind back, I think it may be smoke hoods mouth check valve blocked, it cleaned it. Then, when the upper air pipe is not installed, the ventilator can work normally, but the air pipe is plugged in and is not ventilated at once. It should be the check valve at the home flue (that is, where the common air duct is attached), but this part of the pipe is inside the kitchen ceiling. Is there a way to repair or clean the check valve without removing the ceiling? If you look for professionals to come home maintenance, how much is the approximate cost?: If the flue hanging in the shed, it should be at the check out. Check valve with a machine.So I would not advocate the construction of flue hanging in the shed, net height kitchen, gas capacity is small this is big, the flue pipe exposed, there are many ways to deal with it.If the valve stuck inside, also find what professional people, find out what carpenter, solved the problem.

Q: What's the difference between the h76x check valve h77x?: Check JB/T308-2004 "valve type programming method"The first number 7 is the clip typeThe 6 is a double valve swing structure7 butterfly check valveLook at the JB/T8937-2010 "clip on check valve"That's clear

Q: What are the specifications of the DN200 check valve?: DN200 is a specification.The principle of the check valve, the check valve, the opening and closing parts, depend on the flow of the medium and the power to open or close on its own, so as to prevent the backflow of the medium, called the check valve. Check valves belong to the automatic valve, mainly used for one-way flow of media channels, allowing only medium to flow in one direction, to prevent accidents. The check valve is divided into three kinds: lift check valve, swing check valve and butterfly check valve. The lift check valve can be divided into two types: vertical and horizontal. Swing check valve is divided into single, double valve and multi flap type of three. Butterfly check valve for straight through, more than a few kinds of check valve, in the form of connection can be divided into thread connection, flange connection and welding three. A check valve is a valve that automatically prevents the flow of fluid. The disc of the check valve is opened under the action of fluid pressure, and the fluid flows from the inlet side to the outlet side. When the inlet side pressure is lower than the exit side, the valve automatically closes under the influence of fluid pressure, gravity and other factors to prevent fluid flow backwards.
