Q: Furnace blower outlet check valve what: Must install check valve to prevent downtime fan reversal

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

Q: What is the function of the stop valve and check valve installed on the water supply pipe?: The cut-off valve is a common valves, can also be used for throttling, mainly used to connect or disconnect the line of medium, generally not for regulating flows.

Q: Circulating water check valve, I want to ask is not greater than DN600, you can use HBH747H hydraulic butterfly valve closed butterfly valve, less than DN600 of HD43X slow butterfly butterfly check valve, what does hydraulic check mean? Need hydraulic?: If it is water medium butterfly valve, in fact, the same, are used to prevent the media back of the valve, on the models are manufacturers themselves, there is no uniform standard, but only in the use of media on the difference.Butterfly buffer check valve is to rely on the flow of the media itself and automatically open and close the valve, used to prevent the media back of the valve, also known as check valve, one-way valve, counter flow valve, and back pressure valveMicro resistance slow closing check valve, also known as check valve, its role is to prevent the medium back flow in the pipeline.

Q: The air pipe is equipped with a check valve: [air pipe with check valve] wind pipe with check valve, is to prevent changes in the direction of the wind generated negative pressure, the phenomenon of air intrusion.[duct] is a pipe system for air delivery and distribution.[check valve] refers to the flow itself depends on the media itself and automatically open and close the valve, 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: What type of check valve is the h61y-40 check valve?: The disc type check valve is simple in structure and can only be installed on the horizontal pipe. The sealing performance is poor. Five. Check valves: Valves sliding along the centerline of the valve. Pipe type check valve is a new kind of valve. It is of small size, light weight and good processing technology. It is one of the developing directions of check valve. But the coefficient of fluid resistance is slightly larger than that of the swing check valve.

Q: Exhaust hood at home, the wind back, I think it may be smoke hoods mouth check valve blocked, it cleaned it. Then, when the upper air pipe is not installed, the ventilator can work normally, but the air pipe is plugged in and is not ventilated at once. It should be the check valve at the home flue (that is, where the common air duct is attached), but this part of the pipe is inside the kitchen ceiling. Is there a way to repair or clean the check valve without removing the ceiling? If you look for professionals to come home maintenance, how much is the approximate cost?: If the flue hanging in the shed, it should be at the check out. Check valve with a machine.So I would not advocate the construction of flue hanging in the shed, net height kitchen, gas capacity is small this is big, the flue pipe exposed, there are many ways to deal with it.If the valve stuck inside, also find what professional people, find out what carpenter, solved the problem.

Q: Is the check valve a check valve? What is its main purpose?: Check valve, also known as one-way valve or check valve, its role is to prevent the medium back in the pipeline.

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?: 2.3 installation methods and installation quality2.3.1 since the water meter is now out of the door, most of the units are all concentrated in one box and installed on the first floor. Taking into account the freezing cold winter and the meter, with 6 or 12 meter with a diameter of 40mm- 50mm diameter pipe, tables and small spacing and straight sections set aside less water, this will also affect the normal water metering, causing water rotation.2.3.2 installation quality, pipeline projects are basically buried in the ground or in the wall, is a hidden project. National construction standard pipe provides various pipe pipeline construction installation requirements, construction process, acceptance criteria and matters needing attention, but in the construction site, some managers do not according to the requirements of the code construction, more or less there are some quality problems caused by pipeline.

Q: I have to use a check valve to prevent return water due to pipe installation problems due to regular water supply. But the recent discovery of a running water phenomenon, just on a full tank of water slowly from the pipeline flow away, but not all go, a flow did not flow, time is not the same, but sometimes sometimes does not flow, this is going on, ask professional personage answer: You should be horizontal check valve, with pressure difference, water pressure is not lost; or a check valve inside where the card, must be a certain pressure to baffle back.The problem can't be solved: if you change the pipe, you'll have a vertical check valve
