Q:To prevent water meter rotation, where should the check valve be installed?
Place it at the top of the water meter, as you can see, near the valve
Q:Above the flue that valve is called smoke exhaust valve or check valve, I heard there is a five anti exhaust valve
The names are different, and they are acceptable. Five, anti exhaust valve is unique to 10000, the first class of technical effects
Q:Can the flue check valve and kitchen check valve protect against odor?
Not really. It depends on what valve it is. If it is a variable pressure air valve, of course, if it is an ordinary other valves, generally only temporary role. Five residential home kitchen platoon smoke system is the application of this variable pressure air valve.
Q:Classification of check valves
Check valve (One-way valve): 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.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.
Q:What's the use of the 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 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.
Q:If there is no check valve, there will be a reverse flow of water, what is the damage to the pump?
LZ said that the case does not matter with the check valve, in that case, in addition to affecting performance, it does not matter.
Q:What's the difference between a stop valve and a check valve? Is it a valve?
A check valve is a valve that automatically prevents the flow of fluid. The disc of the check valve is opened under the action of fluid pressure, and the fluid flows from the inlet side to the outlet side. When the inlet side pressure is lower than the exit side, the valve automatically closes under the influence of fluid pressure, gravity and other factors to prevent fluid flow backwards. 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. Among them, the check valve belongs to this type of valve, which includes swing check valve and lift check valve. The swing check valve has a hinge mechanism and a gate like valve free against the inclined seat surface.
Q:Standard and specification for stop check valves
Design and manufacture: GB12235 structure length: GB12221Pressure temperature range: GB9131, JB/T74, HG20604Connection flange: JB/T79, GB9113, HG20592Test and test: JB/T9092, GB13927
Q:What is the reason that the valve is not used for a period of time?Anonymous browsing | 314 times
4 the vertical lift check valve shall be mounted on a vertical pipe.5, the lift type horizontal check valve shall be installed on the horizontal pipe.6. Do not check the weight of the valve in the line. The large check valve shall be independently supported so as not to be affected by the pressure caused by the piping system.
Q:Can the exhaust air outside the wall be fitted without a check 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 mediumThe installation of check valves (Check, Valve) shall pay attention to the following items:A do not allow the check valve to bear weight in the line, and the large check valve shall be independently supported so as not to be affected by the pressure generated by the piping system.B, when installing, pay attention to the direction of the flow of medium should be in accordance with the direction of the body marked arrow.C and vertical vertical check valves shall be installed on the vertical pipe.D and lift type horizontal check valves shall be installed on horizontal pipes
