Usage/Applications Of Iron Check Valve：
Check valve is to rely on the flow of the media itself and automatically open, close the valve flap, used to prevent the media back valve, also known as the check valve, Dan Xiangfa, counter flow valve, and back pressure valve.
Check valve is an automatic valve, its main role is to prevent the media back, to prevent the pump and drive motor reversal, as well as the release of the container medium.

- Q: Check valve 1 inches DN25 what do you mean?
- Crown valve pressFirst, an inch equals DN25That is, fixed values to estimate how large a pipeline isOne inch of check valve is mostly copper check valveThe price of I should be around 25 yuan
- Q: What's the difference between a stop valve and a check valve? Is it a valve?
- 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. The function of this type of valve is to allow the medium to flow in one direction and to prevent flow in the direction. Usually the valve is automatically work, fluid pressure flow in one direction, the valve open; the opposite direction of fluid flow by gravity, fluid pressure and valve closing effect on the valve seat, thereby cutting off flow. Among them, the check valve belongs to this type of valve, which includes swing check valve and lift check valve. The swing check valve has a hinge mechanism and a gate like valve free against the inclined seat surface.
- Q: The difference between the micro and slow closing check valve and the silent check valve
- Another micro, slow, closed noise check valve, a little larger flow.Slow closing check valve, also known as check valve or check valve, its role is to prevent the medium back in the pipeline. The opening and closing parts depend on the flow of the medium and the power is turned on or off by itself. The valve that prevents the backflow of the medium is called a 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. This kind of valve should be installed horizontally in the pipeline.
- Q: Check valve does not automatically check back, how to adjust?
- The non-return valve does not automatically check the cause:1, the valve at both ends of the road must be blocked, there is dry ventilated room. Such as long-term storage, should always check rust corrosion.2, the valve should be cleaned before installation and eliminate the defects during transportation.3, the installation must be carefully checked on the valve signs and nameplates are in line with the use of requirements.
- Q: How to prevent the backflow valve of medium
- Check valve operating principleCheck valve refers to rely on the flow of the media itself and automatically open and close the valve flap, used to prevent the media back flow valve, also known as check valve, Dan Xiangfa, counter 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: Which side of the gate is the fire check valve in the pump room?
- The check valve is installed between the shock absorbing flexible joint and the water outlet control valve at one side of the water outlet pipe of the water pump
- Q: What about boiler non-return valve without return?
- Reliably disconnect the front and rear valves of the check valve and open the check valve spool. 1, lift check valve, remove dirt and impurities out of the valve, and the necessary lifting shaft between the sand, and then check the sealing surface (line), install the recovery; 2, open the valve, visible to the rotary valve plate, sometimes is the axis of rotation is not flexible, it will add oil activities for many times, then look at the rotary valve in the fully open, whether the opening angle is too large, can not rely on medium reflux and gravity recovery closed, if so, then the opening plus limit (which can be in the spool in the valve plate drilling and tapping screw, in a small Luo Si), do not let the valve plate open to the vertical state, which can be opened to an angle of 80 degrees. You can have a try. Good luck. Happy new year.
- Q: We are high-rise buildings, with the smart recharge meters, before always someone to reflect the water used soon, 27 tons of water in only a month has gone. Later I heard that the water meter in front of a check valve on it, but when the five tons of water after the use of nothing, and nothing. Why does that happen? Does the check valve stop the water meter from idling?There is a special case, thirty storey building, booster pump has a pressure in the debugging of the fifteenth layer of what, every time on the twentieth floor of the owners reflect his home water intermittent, sometimes when a shower suddenly no water, we always to reflect the property many times, we are the plumber debugging a few times, or not. Later said that can not be adjusted, and then the tune will burst, and this is how it happened? How can I solve this problem? Why didn't the owners of the thirty and fifteen floors reflect the shortage of water pressure? But the owners of the more than 20 floors are so unlucky?
- 4. conclusionMany reasons for water rotation, but on the whole can be divided into two: one is the subjective factors, namely subjective causes, such as construction acceptance, human responsibility caused by Water Leakage, original gas gathering, which can strengthen the construction management, improve the staff's work and to improve the level of responsibility. The two is the objective factors, the main characteristics of the water itself, by the characteristics of pipeline and the level of technology development in the external objective factors, on the one hand to work in the future continue to explore the improvement will be improved.
- Q: For home use, self suction pumps are installed outside the well and pumped into the water tank.Please check with the self-priming pump function (check valve, water valve)? If not, is not installed in the pipeline connecting wells and pumps? Thank you。
- Water inlet generally has a check valve, if not, then only in the suction port on the installation of the check valve. Of course, you can also install a one-way valve on the pipe near the suction port.
- Q: How can the fast closing noise check valve prevent water hammer?
- It is recommended to see the principle of water hammer in fluid mechanics and the structure and principle of the check valve. These are not a few words to talk about, you can understand, and the important thing is to study your own! Only in this way can I really understand.
