Wafer Check Valve

Q: What's the difference between a stop valve and a check valve? Is it a valve?: The cut-off valve is a common valves, mainly used to connect or disconnect the line of medium, generally not for regulating flows.globe valves for a wide range of pressure and temperature, but are generally used for medium and small diameter pipes. The cut-off valve is closed parts (valve) moving along the centerline of the valve seat valve. The stop valve is mainly used for cutting in the pipeline.

Q: Check valve symbols?: 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.The opening and closing parts depend on the flow of the medium and the power is turned on or off by itself.

Q: Are the common check valves stand upright or horizontally installed?: 1 straight through lift check valve should be installed in horizontal pipe, when the media to stop the flow, the valve by the weight of landing on the seat to prevent the media back; because the vertical lift check valve medium inlet and outlet channel direction and the direction of the valve seat, so it must be installed in a vertical pipe.

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)?: The principle is feasible, but the opening is definitely lagging behind, it will lead to poor ventilation, it is not recommended.AskOh, well, I see. I'll put him in the front. But in this case due to installation problems, only to fan up.

Q: How do I use the triangle and check valves?: The triangle valve is used for connecting taps and water equipment. Check valves are used to prevent backflow of water.

Q: Are the gate valves and check valves of the same type?: Check valve is a check valve function, is to prevent the media back, it is by the valve on the pin shaft and the rotary switch to play the role of the valve with different things, when it is opened by medium pressure automatic opening, closing time depending on the medium and back type the self gravity valve closed, it is a kind of automatic gate valve function, does not require an external force is applied to it, it is a demand for the direction.

Q: What type of check valve should be installed before the suction pump?: Swing, turn, or automatic (note, anyway) can be.

Q: How to install the kitchen flue check valve?: To see what the pipeline, the installation of the location of pipe drilling (Professional) wall pipe, according to the back valve installation size, with percussion drilling, with expansion bolts fixed. The calcium carbonate pipeline is directly fixed with screws (hardness is better)

Q: I use water pump pumping 78 meters deep underground water, the pipe is 2.5 inches large, with ordinary check valve, water is always sucked back, I would like to ask what method or what kind of check valve to be selected (check valve to be installed on the side of the pump): (1) for high and low pressure check valves under DN50mm, vertical lift check valves and straight through lift check valves shall be used.(2) for low pressure check valves under DN50mm, butterfly check valves, vertical lift check valves and diaphragm check valves shall be used.(3) for DN larger than 50mm, less than 600mm high and medium pressure check valve, it is better to use the swing check valve.(4) for DN is larger than 200mm, less than 1200mm of medium and low pressure check valve, should choose no wear ball check valve(5) for DN larger than 50mm, less than 2000mm low pressure check valve, butterfly butterfly valve and diaphragm check valve should be selected.(6) for the requirements of closing perfume, impact is relatively small or no water impact on the pipeline, you should choose the slow closed swing check valve, butterfly butterfly valve.(7) for the import pipeline pump, should use the bottom valve.

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
