- Q: The difference between the micro and slow closing check valve and the silent check valve
- Another micro, slow, closed noise check valve, a little larger flow.Slow closing check valve, also known as check valve or check valve, its role is to prevent the medium back in the pipeline. The opening and closing parts depend on the flow of the medium and the power is turned on or off by itself. The valve that prevents the backflow of the medium is called a check valve. Check valves belong to the automatic valve, mainly used for one-way flow of media channels, allowing only medium to flow in one direction, to prevent accidents. This kind of valve should be installed horizontally in the pipeline.
- Q: What is the check valve?
- Check valve, also known as one-way valve or check valve, its role is to prevent the medium back in the pipeline. Pump water off the bottom valve check valve also belongs to class.The opening and closing parts depend on the flow of the medium and the power is turned on or off by itself. The valve that prevents the backflow of the medium is called a check valve. Check valves belong to the automatic valve, mainly used for one-way flow of media channels, allowing only medium to flow in one direction, to prevent accidents.
- Q: Only one is a soft seal and one is hard sealed
- Swing check valve is a check valve, the structure of the valve for the rotation of the axis of the general term, rubber valve check valve is people's usual name for H44X, only a swing check valve
- Q: What is the function of the check valve on the air compressor?
- Check valve to prevent backflow of gas compressor back to the machine in a series of problems, as followsA gas flow will lead to failure, load startup, startup process if the machine internal high pressure will cause the motor overload start, starting current of the motor will be too high, at the same time, the impact of transmission components is also very large, generally good machine will be some type of protection.Two, multiple units of the system may make the tank filled with water, resulting in the unit can not start properly.Three, because of the shutdown state, most of the air compressor unloading valve is open, so if the gas flow back, but also cause energy losses.
- Q: What about boiler non-return valve without return?
- Reliably disconnect the front and rear valves of the check valve and open the check valve spool. 1, lift check valve, remove dirt and impurities out of the valve, and the necessary lifting shaft between the sand, and then check the sealing surface (line), install the recovery; 2, open the valve, visible to the rotary valve plate, sometimes is the axis of rotation is not flexible, it will add oil activities for many times, then look at the rotary valve in the fully open, whether the opening angle is too large, can not rely on medium reflux and gravity recovery closed, if so, then the opening plus limit (which can be in the spool in the valve plate drilling and tapping screw, in a small Luo Si), do not let the valve plate open to the vertical state, which can be opened to an angle of 80 degrees. You can have a try. Good luck. Happy new year.
- Q: Do you still need to check valve fittings for solar water heater installation?

- Q: How to install fire fighting pipe and flue fire check valve?
- 1, vertical transport, the flue should take protective measures, and must be two lifting.2. Locate the center line of the flue position. In the reserved hole, draw down four vertical central lines from the roof, and draw 2 orthogonal central lines on the floor plane.3, the flue to the scene, the first flue hanging to the roof, surrounded by the center line of pop in the flue, and the flue of the reserved hole slowly down the electric hoist, from top to bottom layer installed flue in place, the center line correction. The center line of the flue and the center line of the reserved hole should be less than 1cm, the deviation of the centerline of the upper and lower flue is not greater than 1cm, and each flue must be guaranteed vertically and vertically.
- Q: Is there a check valve with a relief valve above?
- Fire check valve is used in the fire pump and fire water tank water outlet flow pipeline, pump regulator with control flow unidirectional flow device where the control flow only one-way flow valve; fire safety valve is used to pump combination device and fire pump outlet pipe to control the pipeline pressure does not exceed the pressure will need to use.
- Q: Does the Vatti range hood e601a2z have check valves?

- 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.
