Q:What kind of check valve is used in the sewage pump of sewage treatment plant?
3. to prevent hydraulic impact on the check valve sealing surface damage protection measures, check valve settings, to prevent the backflow of material, pump impeller to avoid the impact of the role of liquid. But as for the check valve itself, improper setting will cause a sudden impact of the disc on the valve seat by the water hammer, and damage the check valve sealing surface. Therefore, several protective measures should be taken. 1, for the pump outlet set >80mm swing check valve, horizontal installation should be adopted to weaken the valve seat back and the impact. 2, for the pump outlet check valve >=150mm diameter of the pipeline, should be placed before and after the bypass valve, to prevent the pressure before the valve rises too high, the check valve sealing surface damage. 3, the pump discharge pipeline starting and ending pressure is higher, the pipeline is not allowed to set the bypass, you can take the following measures. Set up safety valve instead of bypass valve. The action is similar to that of the bypass valve. It is located near the check valve outlet. When the water hammer causes the pressure to rise, a part of the water can be released to prevent the damage caused by the pressure rising. An air or inert gas buffer tank can be set. It is located near the check valve outlet, and when the water hammer is produced, the pressurized gas is compressed through the buffer tank to alleviate the pressure rise caused by the water hammer.
Q:How many kinds of structure are there in the check valve?
1. The structure of the lift check valve is similar to that of the globe valve. Its valve moves up and down along the central line of the channel. The action is reliable, but the resistance of the fluid is large. It is suitable for small caliber occasions. The lift type check valve has an air passage type
Q:Check valve does not automatically check back, how to adjust?
4 the vertical lift check valve shall be mounted on a vertical pipe.5, the lift type horizontal check valve shall be installed on the horizontal pipe.6. Do not check the weight of the valve in the line. The large check valve shall be independently supported so as not to be affected by the pressure caused by the piping system.
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:Check valve 1 inches DN25 what do you mean?
Crown valve pressFirst, an inch equals DN25That is, fixed values to estimate how large a pipeline isOne inch of check valve is mostly copper check valveThe price of I should be around 25 yuan
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 is the difference between the check valve rcvx and SFCV?
3, swing type: liquid in the valve straight through, relying on the pressure to open the side of the rotating valve flap, after the loss of pressure, the valve depends on the weight back, the reverse of the liquid pressure closed valve. Other one-way valves (check valves), such as the sewage check valve, air defense explosion-proof valve and liquid use of the principle of the check valve is very similar.
Q:How to control the common flue return and smoke return?
In the hood outlet to install a reasonable design, shut tight, open the hood in place, can be easily wind blown open, will not be open to the flue suction, and the blade contact area is very small, and a sealing ring, not to hinder the blade opening exhaust flue check valve closed Miller beauty you can eliminate the smoke intrusion and poor smoke.
Q:What type of check valve is the h61y-40 check valve?
Two, swing check valve: the valve swing check valve cylindrical disk-shaped, around the seat of the shaft for rotation channel, because the valve channel into a streamlined, flow resistance than the small valve lift check, suitable for large caliber occasions in low flow and no flow frequently change, but not for the pulsating flow, the sealing performance is less than lift. Swing check valve is divided into single, double, and most types of three, the three forms mainly by the valve bore points, the purpose is to prevent the media to stop flow or reverse flow, weakening the hydraulic impact. Three, compression type check valve: This valve is used as boiler water supply and steam cutting valve, it has lift check valve and stop valve or angle valve comprehensive function. In addition, there are - some do not apply to pump outlet check valve is installed, such as valve, spring-loaded check valve, Y type check valve check valve. Four disc check valve: disc check valve around the pin rotation in the valve seat.
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
