- Q: The working principle and structure description of the mute check valve
- Slow closing check valve and check valve or check valve, its role is to prevent the media back in the pipeline, its working principle is as follows: first, the role of principle: moving through the cylinder plug on the valve flap, assist the rapid opening and closing to the sealing surface two, structure 1 structural forms: swing type 2 single disc drive mode: 3 butt welding connection: open and closed by a pneumatic device to control the butt welding of the 4 valves, speeding up the valve opening and closing speed.
- 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: Pump adapter need check valve?
- Multifunctional pump combination device usually comes with safety valves and check valves, usually in the flange pipe interface or who is interface settings simple check valve, safety valve is white, but does not apply to the north, the northern cold, need to separate the pipes below plus a check valve, a higher temperature of the South may be suitable for direct use of non frozen.
- Q: The difference between the plunger type check valve and the lift check valve
- The two elastic seals are separated by a collar and secured to the sealing ring around the plunger by the load exerted by the valve cover nut on the valve cover. Elastic ring can be replaced, you can use a variety of materials, the valve is mainly used for "open" or "off", but with a special form of plunger or special ring can also be used to adjust flow.
- Q: What's the difference between a throttle valve and a check valve? Are they the same?
- The check valve is directional, so it should be clear when installing. It is like a swinging door that opens in one direction or closes on the other. When the liquid flows towards the opening, the door opens, and when it is stopped, the self pressure of the liquid passing through the door closes automatically and acts as a hindrance to the flow of liquid.Throttle is simple, water switch is one of the throttle 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: Should the flue check valve be made by the civil team or the installation team?
- The kitchen flue and check valve are all constructed by civil engineering.
- Q: Is the flue check valve the same as the flue check valve? What's the difference?
- The flue check valve is not the same as the flue check valve;Flue check valve: a valve that is used at the joint of the hood, flue pipe and flue. Mainly to prevent the role of soot intrusion. The smoke in the apartment building is a public flue, and sometimes the food is always wafted from upstairs to downstairs when cooking, usually from the flue. This check valve can have a certain extent to prevent soot from the role of intrusion, but after all, it is difficult to completely sealed, so the food can not completely prevent the taste of isolation.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.
- Q: An introduction to the check valve
- The check valve, also known as reverse flow valve, check valve, back pressure valve, one-way valve. This kind of valve is automatically opened and closed by the force produced by the flow of the medium of the pipeline itself. It belongs to an automatic valve.
- Q: Is it necessary to install a check valve in the piston refrigeration compressor?
- The small refrigeration system does not require the installation of a special check valve or check valve.Only the larger refrigeration system needs in the pipeline are arranged on the corresponding one-way valve or check valve when using the piston compressor, the main purpose is to prevent too much liquid refrigerant migration to the piston compressor resulting in frozen oil is liquid refrigerant dilution and lubrication performance variation, the compressor with varying degrees of lack of oil operation.
