Usage of Wafer Dual Plate Check Valve

Wafer Dual Plate Check Valve is used in pure line and drain line in many professions such as industry, environment protection, water treatment, high-rise building etc. The check valve is wafer-style, butterfly plate is composed of two semi-circle plates, can be reset by force of spring. The sealing face can be made from ontology surfacing wear-resistant material and rubber bush. This material is widely used, excellent sealing effect.

Q:Are rubber check valves and swing check valves the same type of valves?
Swing check valve is a check valve, the structure of the valve for the rotation of the axis of the general term, rubber valve check valve is people's usual name for H44X, only a swing check valve
Q:Automatic water tower water reflux, plus a check valve not supposed
Check the direction of the installation is correct, check valve quality is good, you can install two 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 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:Check valve does not automatically check back, how to adjust?
7, when installing check valve, should pay special attention to medium flow direction, should make medium normal flow direction and the direction of the arrow on the valve body is consistent, otherwise it will cut off the normal flow of media. Valve should be installed at the bottom of the pump suction pipe.The general formula 8, lift 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.9, the check valve closes, will produce water hammer in pipeline pressure, will lead to serious damage to the valve and piping or equipment, especially for the big pipe or high pressure pipeline, it should pay attention to those who use check valve.
Q:Use of fire pump adapter even before you install a check valve
Multifunctional pump combination device usually comes with safety valves and check valves, usually in the flange pipe interface or who is interface settings simple check valve, safety valve is white, but does not apply to the north, the northern cold, need to separate the pipes below plus a check valve, a higher temperature of the South may be suitable for direct use of non frozen.
Q:How much is the 6 point check valve for the water pipe at home?
1, home hose with 6 points of the water pipe, check valve, copper 20-40 yuan.2, check valve refers 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 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:How can the PPR pipe be connected to the check valve?
The check valve and the PPR pipe are connected by two flanges to the clamp, and the clip type check valve and the two pipes (flanges) are clamped together directly with bolts.
Q:Detailed distinction between backflow preventer and check valve
The backflow preventer consists of two separated check valves and a drain valve. Due to the local head loss of the check valve, the pressure in the middle cavity is always lower than the pressure at the inlet. This pressure difference causes the drain valve to be closed and the pipe is in normal water supply. In abnormal pressure (i.e., the outlet pressure is higher than that of the middle cavity), even if the two check valve can not reverse sealing, safety relief valve can automatically open the reverse water emptying, and the formation of air separation, ensure the health and safety of water upstream.Check valves are plain check valves, only one side seal. Backflow preventer is more expensive than ordinary check valve. Double protection and heavy protection!
Q:The difference between the micro and slow closing check valve and the silent check valve
Micro slow closed silencing check valve hammer to drive the valve plate to open and close, silencing check valve spring pressure valve plate opening and closing, and the price of the body structure is completely different, but the function is the same, if the comparison between the two, large caliber selection micro slow closed check valve a little noise small caliber, the silencing check valve a little more.
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 does the check valve h44t-16 mean?
Flanged swing check valve [H stands for check valve, 4 represents flange, 4 represents structural form (swing type), T represents internal copper alloy, and 16 represents pressure 16 pressure. I hope it will help you
