This valve is installed in pipeline system as a medium against-flow protecting equipment.
- Q:What kind of check valve is used in the sewage pump of sewage treatment plant?
- 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, DN50mmThe 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:What is the function of the check valve in the pipeline?
- An important role for Fujian Biaoguang valve for check valve in the pipeline:The check valve is divided into three kinds: lift check valve, swing check valve and butterfly check valve. The lift check valve can be divided into two types: vertical check valve and horizontal check valve. Swing check valve is divided into single check valve, double check valve and multi flap type check valve three. Butterfly check valve for the straight through check valve, the above several kinds of check valve in connection form can be divided into threaded connection, check valve, flange connection check valve and weld check valve three kinds.
- Q:What does the H/F/P stand for in the check valve H41H/H41F/H41P?
- Respectively, the valve seat sealing surface is made of alloy / fluorine plastic / stainless steel.
- Q:The difference between swing check valve and lift check valve
- Swing check valve, swing check the valve to the disc valve seat around the channel axis for rotation, 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 should not be used 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.
- Q:Are the common check valves stand upright or horizontally installed?
- 2. swing check valves are generally installed on horizontal or vertical or inclined pipes.
- Q:Why is the water ring vacuum pump equipped with check valves?
- The check valve is a one-way valve, the instantaneous vacuum of the stopping pump is higher than the pump cavity, and the gas enters the pump cavity from the exhaust port, and the water pressure is connected to the vacuum pipeline, and the function of the check valve is to prevent water from entering the pipeline
- Q:Assembling process of clip type check valve
- 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 and the sealing surface of the valve seat. 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:Automatic water tower water reflux, plus a check valve not supposed
- Check the direction of the installation is correct, check valve quality is good, you can install two check valve. 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:What is the function of the check valve installed in the water meter before entering the residential water?
- Preventing water backflow is also considered from the point of view of water safety.
- Q:Check valve authentication information
- CE (PED, 97/23/EC) ComplianceCE (pressure equipment, 97/23/ EC) certificationMany Check-All valves comply with pressure equipment instructions (PED, 97/23/EC). Our certificate number, CE62128, was issued by the British Industrial Standards Institute (BSI), and it is also the designated body of compliance assessment for our component H (full quality system).B16.34, Certification, ASME, B16.34 flanges, threaded and welded end connections, valves, certificationsPart of the valve size can be supplied in accordance with the B16.34 certificate.
