- Type: Swing Check Valve
Usage of Flange Swing Check Valve
Various modes of the pipeline, prevent the medium backflow
- Products Design Features: Flanged & Butt-welding ends swing check valves are used in pipes under pressures between PN 1.6-16.0MPa,Class 150-900Lb,working temperatures between -29-570 °C, They are used in industries include oil, chemistry, pharmaceutical, fertilizer, and power generation to prevent the backward flux of the media.
- Method: Handle operation, electric.
- Raw Material: WCB, WC6
- Q:Ask questions about the installation of check valves after water meters
- 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.
- Q:Is it necessary to install a check valve in the piston refrigeration compressor?
- To solve this problem, we first need to know the working cycle of the piston compressor:1, compression process, suction valve closed, refrigerant gas in the cylinder from low pressure to high pressure process;2 the exhaust process, compression end, from the cylinder through the exhaust valve to exhaust pipe process;3, expansion process, exhaust end, exhaust valve closed, the piston from the bottom of the cylinder moving to the top of the cylinder process;4 suction process, suction valve opens, low-pressure refrigerant gas inhalation process of the cylinder;From the above piston engines don't seem to need what steps to open check valve. Because the suction valve and exhaust valve on the cylinder are constantly switching each other, the piston machine continues to inhale and exhaust the process. If only from the piston machine, there is no need to install a check valve.But to consider the whole refrigeration system, rather than a simple piston compressor, when the piston of more than 2 units must be horizontal pipeline in a single compressor exhaust pipe to the exhaust duct installed on the check valve and pipe installation is about
- 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:Can the swing check valve stand upright?
- Ordinary lift check valves shall not be erected. Lift check valves with springs can also be mounted.
- Q:Does one-way check valve affect water flow?
- The water inlet of the household water heater is equipped with a triangle valve, which will not affect the flow of water, and be convenient for maintenance and inspection
- 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:PPR check valve, butterfly valve, as well as water gauge which quota?
- Is that screw valve set? And what's the quota for the deflector?Chasing the answerBackflow preventer can be fitted with check valves.
- Q:Which side of the gate is the fire check valve in the pump room?
- The check valve is installed between the shock absorbing flexible joint and the water outlet control valve at one side of the water outlet pipe of the water pump
- Q:Do you still need to check valve fittings for solar water heater installation?
- Need, the solenoid valve automatically control itself has the function of manual water valve was the installation of the installation, but now a lot of pressure to see you still go not installed, they save cost, but will give users the trouble
- Q:Problems with the check valve of the circulating water pipe
- If it is water medium butterfly valve, in fact, the same, are used to prevent the media back of the valve, on the models are manufacturers themselves, there is no uniform standard, but only in the use of media on the difference.Butterfly buffer check valve is to rely on the flow of the media itself 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 valveMicro resistance slow closing check valve, also known as check valve, its role is to prevent the medium back flow in the pipeline.
