Q: Automatic water tower water reflux, plus a check valve not supposed: Check the direction of the installation is correct, check valve quality is good, you can install two check valve. Check valve refers to rely on the flow of the media itself and automatically open and close the valve flap, used to prevent media backflow valve, also known as check valve, one-way valve, 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.

Q: Does FOTILE hood have check valve?: Therefore, it is necessary to install a check valve at the flue port.

Q: Should the pressure gauge be mounted before or after the check valve at the back of the pump?: If the pressure gauge is installed before the check valve, the normal pressure will be displayed only when the pump is running. The pressure value displayed at the pump is not consistent with the actual pressure of the pipe.

Q: Why should the check pipe be added to the chilled water pipe of the air conditioning unit?: The air conditioning water chiller is usually installed in the basementNo check valve, pump start pressureThe current is likely to boil the pump when the building is high

Q: Which type of check valve should be selected for vertical pipes?: The check valve on the vertical pipeline shall ensure that the spool goes back to its position when the fluid is stationary and reversed.Optional:Butterfly check valves, pipes of low pressureVertical lift check valve, high pressure resistance, good tightnessSwing check valve: flow must be from the next up, the pipe diameter is unlimited

Q: Is the hdf41x 1.6Mpa a check valve?: The backflow preventer consists of low pressure backflow prevention device and vacuum type backflow prevention device two, according to the national standard of low pressure backflow prevention device of head loss is less than 3 meters, decompression type backflow prevention device of head loss is less than 7 meters.

Q: What's the difference between a throttle valve and a check valve? Are they the same?: The same valve, but the effect is entirely different.The so-called "check back" is to let the fluid in the pipeline can only flow in one direction, can not let it return, so it is also called one-way valve. It works automatically.

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: What is the difference between the check valve and the check valve?: 1, spring: the liquid from the bottom up, rely on the pressure spring controlled valve, the pressure disappears, the spring force the valve, sealing liquid backflow. Often used in the smaller diameter check valve.2, gravity: and spring similar to rely on the valve's own gravity closed to prevent backflow.3, swing type: liquid in the valve straight through, relying on the pressure to open the side of the rotating valve flap, after the loss of pressure, the valve depends on the weight back, the reverse of the liquid pressure closed valve. Other one-way valves (check valves), such as the sewage check valve, air defense explosion-proof valve and liquid use of the principle of the check valve is very similar.

Q: Installation position of air pipe check valve: Texture of material1. cast iron check valve2. brass check valve3. stainless steel check valve4. carbon steel check valve5. forged steel check valveCheck 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).The function of this type of valve is to allow the medium to flow in one direction and to prevent flow in the opposite 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.
