- Q: Check valve note BC/PISTON: SPR-L what does that mean?
- BC==Bolted Cover/ bolted bonnetPISTON== lifting typeSPR-L==Spring-loaded/ is loaded with springsTogether, it is: a spring-loaded check valve. Bolted bonnet (this is common)
- Q: What's the function of the small check valve on the deep well pump? Solve!When the deep well pump works, it does not move inside! Under great pressure！ There is a hissing sound when the deep well pump doesn't work! The air is in! Will it lead to the water in the room? There's a lot of air in it!
- This valve is to stop the pump when the intake, through the intake of water to cut off the backflow, to prevent water from being returned to empty, the air can not enter the valve above the part of the water pipe, rest assured
- Q: What does the check valve "h61h-25 H" mean?
- The first h or the latter H?According to the provisions of the JB/T 308-2004 valve type programming method:H = check valve6 = connection: Welding1 = structure form: lifting typeH = sealing surface material: Cr13 stainless steel
- Q: What can I do with the lift check valve?
- Standard light valve for you to answer, lift check valve is to rely on the media itself flow 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.
- Q: Is it necessary to install a check valve for suction well pumping well? If you need to install what kind of check valve (about lifting, butterfly valve, also a what to forget), which (installed in the water outlet, water inlet, or water pipe), ask again need to install the filter valve? I do not understand, ask for expert doubts! Thank you very much!
- Selection of check valve for pump outlet check valveGeneral pump station project, for the pump outlet check valve, the following principles should be observed;The outlet check valve shall be used when the diameter of the outlet pipe of the pump is smaller, that is, DN50mm.The pipeline of the pump outlet pipe diameter DN is larger than 50mm, should be used in swing check valves can be installed horizontally or vertically. Swing check valve to rotate around the shaft, the fluid resistance is generally less than the lift check valve, which applies to the larger diameter of the occasion, the installation location restrictions, usually installed in horizontal pipelines, it applies with large 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 for medium and medium duty applications. Large diameter pipeline using single swing check valve, in order to reduce the water hammer pressure, it is best to use water hammer to reduce the pressure of the slow closing check valve. Double valve swing check valves are suitable for large and medium diameter pipelines. Double check swing check valve with small structure and light weight is a fast check valve. Multi disc swing check valve is suitable for large diameter pipeline
- Q: How to prevent the backflow valve of medium
- Among them, the check valve belongs to this type of valve, which includes swing check valve and lift check valve. The swing check valve has a hinge mechanism and a gate like valve free against the inclined seat surface. In order to ensure that the valve can reach the appropriate position of the seat surface at any time, the disc is designed in the hinge mechanism so that the disc has enough swing space to make the disc real and comprehensive contact with the valve seat. The disc can be made of either metal or leather, rubber, or synthetic coverage, depending on performance requirements. The swing check valve is almost completely open and the fluid pressure is almost unimpeded, so the pressure drop through the valve is relatively small. The check valve of the lift check valve is located on the valve seat sealing surface of the valve body. In addition to this valve disc is free to lift, like the rest of the cut-off valve, the fluid pressure valve from the valve seat sealing surface lift, medium return led down to the valve seat, and cut off the flow. Depending on the service conditions, the disc can be of all metal construction or in the form of a rubber pad or rubber ring on the valve frame. The same as the cut-off valve, lift check valve fluid through the channel is narrow, so the check valve by lifting the pressure drop than the swing check valve a little bigger, and swing check valve flow restrictions very little.
- Q: Install check valve is not afraid of water, in case the back of the water pollution?
- The function of the check valve is to prevent water from flowing back. It is mainly used at the pump outlet to protect the water pump. Of course, it is also possible to prevent backwater pollution. Where to use it, mainly to function, is not necessarily to be applied in a traditional way!
- Q: I have to use a check valve to prevent return water due to pipe installation problems due to regular water supply. But the recent discovery of a running water phenomenon, just on a full tank of water slowly from the pipeline flow away, but not all go, a flow did not flow, time is not the same, but sometimes sometimes does not flow, this is going on, ask professional personage answer
- You should be horizontal check valve, with pressure difference, water pressure is not lost; or a check valve inside where the card, must be a certain pressure to baffle back.
- Q: Can the exhaust air outside the wall be fitted without a check valve?
- The backflow valve of the exhaust fan is usually installed. It is a method to prevent the air flow from returning to the fan when it is stoppedIf your fan is just outside the wall, you can't install it,But if it is a blast of contaminated air or a dilution of dangerous air flow, it is better to have it installedCheck 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.
- Q: Are check and check valves the same kind of thing?
- The same thing is not the same as it is
