Ductile Iron Check Valve DN1400 Quality Guarantee China

Q: What happens when the check valve is broken?: 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 reverse of the pump and drive motor and the leakage of the container medium.If the check valve is broken, there will be media backflow, pump and drive motor reversal, as well as the leakage of container media

Q: Why can't parallel check valve be installed firmly?Anonymous browsing | 51 times: The vertical installation is easy to cause the valve core of the check valve to clamp off or fall off, and lose the function of checking back. The direction of the check valve is restricted seriously from any direction of the medium

Q: Should the pressure gauge be mounted before or after the check valve at the back of the pump?: If installed after the check valve, no matter how the pump operation, will show the actual pressure in the pipe.In order to facilitate the replacement, you can install a small valve on the main pipe to connect the pressure gauge on the small pipe. When you change the pressure gauge, you only need to turn off the small valve

Q: The principle of the check valve: The function of the check valve is to allow the medium to flow in one direction only, and to prevent the flow in the opposite direction

Q: Back pressure valve and check valve difference: Oil is generally put into the wells of the check valve calling back pressure valveCheck valve is a general name, mainly lifting type and swing type.

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: An introduction to the check valve: The check valve, also known as reverse flow valve, check valve, back pressure valve, one-way valve. This kind of valve is automatically opened and closed by the force produced by the flow of the medium of the pipeline itself. It belongs to an automatic valve.

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。: Self suction pump reverse water valve is a 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. 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 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.

Q: Install check valve is not afraid of water, in case the back of the water pollution?: The function of the check valve is to prevent water from flowing back. It is mainly used at the pump outlet to protect the water pump. Of course, it is also possible to prevent backwater pollution. Where to use it, mainly to function, is not necessarily to be applied in a traditional way!

Q: Fire hood fire check valve okay?: All smoke hoods are equipped with check valve, that is, when the hood is not used, the airflow outside into the kitchen
