Q: Furnace blower outlet check valve what: One can be installed to prevent the backflow of high temperature gas in the boiler

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

Q: What is the material of H41W-16's check valve?: Both cast iron and stainless steel are possible

Q: Butterfly check valve should be equipped with special flange for butterfly valve: No, with a special appearance Jansen point flange butterfly valve. It can barely be installed without special flanges

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: Where can I find the good check valve?: Northeast, I think the quality is better

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's the difference between the H76H model and the H76J check valve?: Check valve additional number: HH, micro resistance, slow closing check valve, BH Insulation check valve, HQ ball type check valve;The check valve type: H on behalf of check valve;The check valve flange connection: 4, 6, 7 for welding clamp;The check valve: 1 lift, 2 vertical, 4 swing, 6 double disc, 8 butterfly;The check valve seal: B Babbitt, F fluorine plastic, H stainless steel, Monel alloy, cast M direct machining of X rubber, Y hard alloy, W;The check valve pressure: 16 pressure of sixteen kg,

Q: What is the HC41X-16Q model of the optical valve? What is its main function?: 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. Not suitable for medium containing solid particles and viscosity. When the medium according to the provisions of the direction of flow, the valve by the media force, is open;

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.
