Q:What's the difference between check valves and non-return valves?
Other check valves (check valves), such as blowdown check valves,Civil air defense explosion-proof valve and liquid use of the principle of the check valve is very similar.
Q:Does the tap water return to the water?
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:Ball shaped sewage check valve pictures and working principle of the structure.
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 selection
(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:What's the difference between a stop valve and a check valve? Is it a valve?
The cut-off valve has the following advantages: 1. in the process of opening and closing, the friction of the sealing surface is smaller than that of the gate valve, and it is wearable. 2. high opening height. 3. usually only a sealing surface, the manufacturing process is good, easy to repair. The valve is widely used, but because the opening and closing torque is large, the structure length is longer, usually the nominal diameter of DN are limited to the following 200mm. The flow resistance of the stop valve is greater. Thus limiting the wider use of cut-off valves.
Q:What are the differences between the vertical check valve and the horizontal check valve?
The main difference is whether the valve center and valve seat are placed horizontally or vertically. It is usually designed with the pipe
Q:How to use the check valve when the size of the pressure?
When using check valves, the magnitude of the pressure shall correspond to the pressure level of the pipe
Q:What is the function of the check valve installed in the water meter before entering the residential water?
Generally installed after the water meter. The main reason: if the water point is higher than the water meter installation position, once the pipe network in the absence of water, the remaining water in the pipeline will flow in the direction of the water meter in turn. This will cause the water meter to reverse and cause damage to the water meter. A check valve is installed after the water meter, so that the situation can be avoided.The main function of the check valve is to prevent the backflow of the medium, prevent the reverse of the 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:Is the overcurrent valve a check valve?
The overflow valve is just a pipe overflow pronounSuch as decompression, flow valve, butterfly valve, flow valve and so onActually, they are all called in the front wordsTherefore, can not be replaced to illustrate
Q:Why can't parallel check valve be installed firmly?Anonymous browsing | 51 times
The vertical installation is easy to cause the valve core of the check valve to clamp off or fall off, and lose the function of checking back. The direction of the check valve is restricted seriously from any direction of the medium
