- 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: What is the check valve?
- Check valve (cheek 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.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 and horizontal. Swing check valve is divided into single, double valve and multi flap type of three. Butterfly check valve for straight through, more than a few kinds of check valve, in the form of connection can be divided into thread connection, flange connection and welding three.
- Q: How many kinds of check valves should be used?
- Ball check valve because the sealing part is covered with rubber ball, therefore, good sealing performance, reliable operation, anti water hammer performance; the seals can be a single ball, they can make more balls, so you can make large caliber. But its seal is wrapped in rubber hollow sphere, does not apply to high pressure pipeline, only applies to the middle and low pressure pipeline.Because the shell material of spherical check valve can be made of stainless steel, sealed hollow sphere parts can be coated PTFE plastics, can also be applied in the pipeline so general corrosive medium.The check valve in the working temperature between -101~150 DEG C, the nominal pressure is less than 4.0Mpa, nominal in the range of 200~1200mm
- Q: What does the number 16 on the check valve mean?
- This is the pressure level of the valve, which represents 16Kg, which is used for piping pressure less than this pressure.
- Q: Can the check valves fit two in one tube? One up, the other down
- Launching, then you'd like to have a Sheung Shui at the front of the Sheung Shui
- Q: What type of check valve is the h61y-40 check valve?
- The disc type check valve is simple in structure and can only be installed on the horizontal pipe. The sealing performance is poor. Five. Check valves: Valves sliding along the centerline of the valve. Pipe type check valve is a new kind of valve. It is of small size, light weight and good processing technology. It is one of the developing directions of check valve. But the coefficient of fluid resistance is slightly larger than that of the swing check valve.
- Q: What is the function of the check valve in the pipeline?
- 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 valve is automatic valve, check valve is mainly used for one-way flow of media channels, allowing only medium to flow in one direction, to prevent accidents.The installation of the check valve shall pay attention to the following1. Do not allow the check valve to bear weight in the line. The large check valve shall be independently supported so as not to be affected by the pressure caused by the piping system. 2, installation, pay attention to medium flow direction should be in accordance with the body of the ticket arrow direction.3, vertical lift check valve should be installed on the vertical pipe.4, lift type horizontal check valve should be installed in the horizontal pipe.
- Q: Does the check valve of the flue of the range hood work?
- The picture of the check valve of the flue of the range hood is as follows:In addition there is a full sealed flue check valve or smoke exhaust hood treasure is installed in public on the flue pipe valve, exhaust valve to open the hood, hood stop valve is closed, the current Taobao sold this kind of sealed check valve is more, we also evaluated very high. Pictures are as follows:
- 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: Is it better to have explicit rules in the relevant specifications? Thank you, ah, ah, urgent.
- Article 8.5 of the code for fire protection design of high-rise civil buildings provides as follows:8.5.3 one of the following circumstances shall be equipped with fire dampers for the ventilation and air conditioning systems:8.5.3.1 pipe through fire compartment.
