Q:Installation position of air pipe check valve
The air pipe check valve is installed in an air conditioner or a pipeline, and when the fan is in operation, the blade is lifted and the air flow passes smoothly; when the fan stops, the valve blade is closed, and the backflow of gas is prevented. But the wind speed in the air duct must not be less than 8m/s. (it can be made into explosion-proof type or pneumatic type)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:An introduction to the check valve
The check valve, also known as reverse flow valve, check valve, back pressure valve, one-way valve. This kind of valve is automatically opened and closed by the force produced by the flow of the medium of the pipeline itself. It belongs to an automatic valve.
Q:What are the specifications of the DN200 check valve?
The silent check valve is suitable for water supply and drainage, fire fighting and heating and ventilation systems. It can be installed at the outlet of water pump to prevent the backflow of medium and the damage of water hammer to the pump.Liquid control check valve is suitable for the pump outlet pipe of medium water, as closed circuit and check valve. It is used to avoid and reduce the medium prosperity, reverse flow and excessive water hammer in pipeline system, so as to protect pipeline system.The swing of the swing check valve rotates around the shaft. Its fluid resistance is generally smaller than the lift check valve, it applies to larger caliber occasions. Swing check valve according to the number of valves can be divided into single swing type, double valve swing and multi valve swing type of three. Single swing check valves are generally suitable for medium calibre applications.The structure of the lift check valve is similar to that of the globe valve. The valve is used to move up and down along the channel. The action is reliable, but the resistance of the fluid is large. It is suitable for light and small caliber occasions. Lift check valves can be straight through and vertical two. Straight through lift check valve can only be installed in horizontal pipe, vertical lift check valve is usually installed in vertical pipe.The micro resistance slow closing check valve is used for the water supply and drainage pipeline and is installed at the outlet of the water pump to prevent the medium reverse flow and eliminate the destructive water hammer, and can effectively reduce the water hammer pressure of the valve closing, and can ensure the safe operation of the pipe network.
Q:Is the tank stop valve a non-return valve or a check valve?
The valve has a knob, and the controller can control the forward flow. Because of its special structure, the fluid can not flow backwards even if there is no artificial valve.
Q:How do I install the pump outlet check valve?
Order note: 1. Pump outlet check valveProduct name and model number 2. Whether or not to take accessories for our correct selection. Use pressure. Use medium temperature.Two, if the company has been selected by the design unitPump outlet check valve type, please pump outlet check valveThe model is ordered directly from our sales department.Three, when the use of the occasion is very important or the environment is more complex, please try to provide design drawings and detailed parameters, by our valve company experts for your audit checks. If you have any questions: please call us for advice:,We will do our best to provide you with quality service.
Q:What's the difference between the cut-off check valve and the stop valve?
Purely from the outward appearance is indistinguishable, but if you do not open the valve body, it can still be differentiated. Turn off the check valve and stop valve (turn the handwheel to the open, the valve stem up), and then shake the two valve, which is relatively large movement, then this is the cut-off check valve.
Q:Is it necessary to install a check valve in front of the water meter? Does the water company have a definite requirement?
UnnecessaryWater meter before the loss of running water, their own things, do not need customers to bearAfter the water meter is equipped with a small gate valve or a ball valve, it is convenient to repair and replace
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:How many kinds of structure are there in the check valve?
2. The swing check valve rotates around the shaft. Its fluid resistance is generally smaller than the lift check valve, it applies to larger caliber occasions. According to the number of valves can be divided into single swing type, double valve swing and multi valve swing type of three. Single swing check valves are generally applicable to medium calibre applications. Large diameter pipeline using single swing check valve, in order to reduce water hammer pressure, it is best to use water hammer to reduce the pressure of the slow closing check valve. Double check valves are suitable for large and medium diameter pipelines. Double check swing check valve with small structure and light weight is a kind of fast developing check valve. Multi valve check valve is suitable for large caliber pipeline;
Q:What is the reason that the valve is not used for a period of time?Anonymous browsing | 314 times
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.
