Q:How can the PPR pipe be connected to the check valve?: The check valve and the PPR pipe are connected by two flanges to the clamp, and the clip type check valve and the two pipes (flanges) are clamped together directly with bolts.

Q:The difference between check valve and check valve: 1, one-way valve: is a typical seat valve, one-way valve Check, Valve, also known as check valve or check valve. Used in hydraulic systems to prevent reverse flow of oil flow. There are two one-way valve one-way and right angle type. Straight through one-way valves are threaded and installed on the pipe line. The right angle one-way valve has threaded connections, plate connection and flange connection in three forms. Liquid control check valve, also known as blocking valve or pressure valve, which is the same as one-way valve, used to prevent reverse flow of oil. But in the hydraulic circuit needs the oil flow reverse flow, but also can use the control oil pressure, opens the one-way valve, causes the oil flow to be possible to flow in two directions. The hydraulic control check valve adopts a conical valve core, so the sealing performance is good. When the closed oil circuit is required, the valve can be used as the one-way locking of the oil circuit to maintain the pressure. Liquid control check valves control the leakage of oil, there are two types of internal and external leakage. In the oil flow reverse outlet, no back pressure in the oil pipeline can be used to vent type; otherwise, need to leak type, in order to reduce the control oil pressure2, check valve is only one kind of valve, it can be said that one-way valve is a kind of check valve,

Q:How to use the check valve when the size of the pressure?: 1) check valve: generally applicable to clean medium, should not be used for containing solid particles and viscosity medium.2), for the low pressure below DN50mm check valve, check valve should be selected on the clip, vertical lift check valve; for DN is greater than 200mm, less than 1200mm in the low pressure check valve, should use micro slow close check valve, water hammer eliminating buffer device with valve and check valve; for the low pressure DN is greater than 50mm, less than 2000mm should use check valve, butterfly valve and swing check valve.3), micro slow close check valve for easy to produce water hammer piping on the micro resistance slow closing system can well eliminate the media generated when the water hit counter, but limited by the temperature and pressure, generally used in low temperature pipe.4) for the closing of the water shock or small impact of the water pipeline, it is appropriate to use micro resistance slow closing check valve and buffer butterfly check valve.

Q:What is the reason that the valve is not used for a period of time?Anonymous browsing | 314 times: 1, the valve at both ends of the road must be blocked, there is dry ventilated room. Such as long-term storage, should always check rust corrosion.2, the valve should be cleaned before installation and eliminate the defects during transportation.3, the installation must be carefully checked on the valve signs and nameplates are in line with the use of requirements.

Q:Is the tank stop valve a non-return valve or a check valve?: Check valve is a one-way valve, automatically prevent reverse flow of fluid, no knob, can not be artificial blocking forward flow.

Q:What kind of check valve is used in the sewage pump of sewage treatment plant?: 2. installation of pump outlet check valve*Swing check valves are generally mounted on horizontal pipes: for bore DN~80mm check valves, they can also be mounted on vertical or upward sloping pipes.*Straight through lift check valves shall be installed on horizontal pipes; vertical lift check valves must be mounted on vertical pipes and medium upward flow.*As the check valve is easy to damage, therefore, should be installed near the pump outlet valve, in the upper part of the check valve with a cut-off valve (general use of ball valve or gate valve), easy to overhaul.*To facilitate the relief of the check valve before disassembly, the relief valve shall be installed between the check valve and the shut-off valve.

Q:How do I use the triangle and check valves?: The triangle valve is installed before the sanitary ware, the faucet and the appliance, so that it can be repaired after the damage of the faucet and the appliance.The check valve is equipped with a water meter and the water pump is prevented from flowing backwards in front of various water tanks and water pumps.

Q:What's the size of the check sleeve?: According to the quota items can be set corresponding to the valve diameter less than DN40, the thread sets, DN50 sets of flange connection can, according to the actual unit price to enter it.

Q:What's the use of the 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 the media back flow valve, also known as check valve, Dan Xiangfa, 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. The check valve can also be used to provide a supply to the auxiliary system where the pressure may rise above the system pressure.

Q:Should the flue check valve be made by the civil team or the installation team?: Internal construction, check the inner ring outside the cement glue installed
