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: 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: How many kinds of check valves should be used?
Medium for water, steam, gas, corrosive media, oil, food, drugs and so on. The medium operating temperature range is between -196~800 degrees centigrade.Swing check valves are installed in an unrestricted position, usually installed on a horizontal pipe, but can also be mounted on a vertical or inclined pipe.Butterfly check valve is suitable for low pressure large diameter, and installation occasions are limited. Because the butterfly valve of the working pressure can not be high, but the public can be large, can reach more than 2000mm. But nominal pressure is below 6.4Mpa. Butterfly check valve can be made into pairs, generally installed in the pipeline between the two flanges, using the form of clamp connection.Butterfly check valves are installed in an unlimited position and can be mounted on horizontal or vertical or sloping lines.Diaphragm type check valves are suitable for pipes that are prone to water hammer. The diaphragm can eliminate the water hammer produced by the medium counter flow. As the diaphragm type check valve operating temperature and practical pressure by the diaphragm material restrictions, generally used in low-pressure, temperature pipe, especially for the water pipeline. General medium temperature between -20~120 degrees, the work pressure of less than 1.6Mpa, but diaphragm type check valve can do larger caliber, DN maximum can be more than 2000mm.
Q: How much is the 6 point check valve for the water pipe at home?
Check valve (One-way valve): check valve, also known as one-way valve or check valve, its role is to prevent the medium back flow in the pipe. Pump water off the bottom valve check valve also belongs to class. 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. ... I've done fire fighting... And home water... "It doesn't let the water go back at all" (of course, it doesn't work when it doesn't work.. it doesn't let water run back at all)6 point check valve for home. I bought it in Guilin. That kind of copper is 12 yuan oneThere are questions about the check valve. You can directly search the Baidu encyclopedia can be intuitively responded to.. but the price problem.. every place should be different
Q: What's the difference between the cut-off, check, check, and stop valves three? Better picture,
Stop check valve: when the handwheel is rotated so that the valve stem rises, the disc does not rise together, but only the valve clack is released.
Q: What type of check valve should be installed before the suction pump?
Self priming pumps are equipped with rotary, rotary or automatic type check valves.Check valve, also known as one-way valve or check valve, its role is to prevent the medium back in the pipeline. Pump water off the bottom valve check valve also belongs to class. Forged steel check valves two body cover to connect the design form: the first is the body cover bolt connection forged steel valve, connected by this form of valve, the valve body and the valve cover bolt connection, spiral wound gasket seal, the advantage of easy maintenance;
Q: Check valve in the water pump when the sound of vibration is very large, what is the matter?
For the gas wall boiler heating system, the water from the water booster pump mouth must be installed on the gate for gas wall boiler heating system, water plus appropriate pressure to turn off the gas wall furnace, built in water supply valve, heating system, water flow
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: Is the overcurrent valve a check valve?
The overflow valve is just a pipe overflow pronounSuch as decompression, flow valve, butterfly valve, flow valve and so onActually, they are all called in the front wordsTherefore, can not be replaced to illustrate
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: 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.
