Q:Is the check valve installed at the inlet or outlet of the pump? Why?
Check valves are installed at the outlet of the pump. The reasons are as follows:The function of the check valve in the water supply system of the water pump is to prevent the impact of the high pressure water on the impeller of the pump. System in operation, for some reason, when the water pump suddenly stops running, the pressure inside the pump disappears, and the high-pressure water connected with the water pump outlet will reverse flow backwater pump. When the pump outlet is equipped with a check valve, it will be closed immediately to prevent the high pressure water reverse flow backwater pump. Prevent water pump reverse and so on.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. 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.
Q:Check valve is 150, why not put 150 of the smoke pipe?
DN150 check valve, it is possible that the internal path is less than the required value of 5mm-10mm. Therefore, the 150 outer diameter of the smoke pipe is not up.
Q:Check valve symbols?
The check valve is divided into three kinds: lift check valve, swing check valve and butterfly check valve:1. lift check valve is divided into two types of vertical and horizontal.2. swing check valve is divided into single, double flap and multi flap type of three.3. butterfly check valve is straight through type.The above types of check valves can be classified into thread connection, flange connection, welding connection and clamp connection in connection forms of four kinds.
Q:What does the swing check valve "h44h-16" mean?
H44h-16 is the type of swing check valve, respectively: H check valve, 4 flange, 4 swing type H alloy steel, sealing 16 kg pressure
Q:What kind of check valve is used to prevent the return water?
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
Q:How to install the water pipe check valve?
Check valves are normally installed at the pump's exit position!Check valve, also known as check valve, the specific installation needs to determine the direction of the pipeline!
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:The check valve on the air pipe is installed in front of the fan and is there any difference in the back (direction is correct)?
Yes。Installed in front of the wind blowing, the top open check valveIt is difficult to install the check valve, which is installed on the rear by the force of air suction.
Q:Is the flue check valve the same as the flue check valve? What's the difference?
The same thing, different expressions, that is, in order to prevent channeling smoke smell of Dongdong
Q:The working principle and structure description of the mute check valve
Slow closing check valve and check valve or check valve, its role is to prevent the media back in the pipeline, its working principle is as follows: first, the role of principle: moving through the cylinder plug on the valve flap, assist the rapid opening and closing to the sealing surface two, structure 1 structural forms: swing type 2 single disc drive mode: 3 butt welding connection: open and closed by a pneumatic device to control the butt welding of the 4 valves, speeding up the valve opening and closing speed.
