Q:The role of the clip lift check valve
It only allows the medium to flow in one direction and prevent the 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. Check valves are generally applicable to clean media and are not suitable for media containing solids and viscosity.
Q:Are the common check valves stand upright or horizontally installed?
2. swing check valves are generally installed on horizontal or vertical or inclined pipes.
Q:Furnace blower outlet check valve what
One can be installed to prevent the backflow of high temperature gas in the boiler
Q:What type of check valve should be installed before the suction pump?
Swing, turn, or automatic (note, anyway) can be.
Q:Check valve H41T-16. What are the numbers and letters in it?
H stands for check valve, 4 stands for flange 1, and represents form 16 for pressure. This is cast iron lift check valve
Q:What's the difference between the cut-off check valve and the stop valve?
The principle difference between the check valve and the cut-off valve is that the non-return valve allows only one-way flow of liquid, allowing only one flow from one end to the other. It is a one-way valve, and the shut-off valve allows two-way flow. The biggest difference is the structure of the valve head and valve closing method is connected by the check valve is separated, the appearance of the cut-off valve import and export in a plane and the cut-off valve is a one-way valve, arrow shell stop check valve on the other.
Q:The difference between the micro and slow closing check valve and the silent check valve
Noise 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, noise check valve, reverse 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).
Q:How to install industrial check valves? How should they be used?
1, straight through lift type check valve should be installed in horizontal pipe, vertical lift check valve and bottom valve is usually installed in a vertical pipe on the road, and the bottom-up flow of media.2, swing check valve installation location is not appropriate, usually installed in the horizontal pipe, but can also be installed in the vertical pipe or inclined pipe line.
Q:What happens when the check valve is broken?
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 reverse of the pump and drive motor and the leakage of the container medium.If the check valve is broken, there will be media backflow, pump and drive motor reversal, as well as the leakage of container media
Q:How to prevent the backflow valve of medium
Check valve operating principleCheck 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).
