Error code of pneumatic flange butterfly valve for water conservancy Analysis of metal pneumatic butterfly valve?
Analysis of metal pneumatic butterfly valve Pneumatic butterfly valve's request for hydraulic oil:
The vibration principle is to absorb the vibration energy and shock wave brought by electric vehicle vibration through the damping characteristics of hydraulic oil, and then convert them into warm evaporation. Therefore, the quality and viscosity of hydraulic oil are directly related to the damping force provided and the damping effect of pneumatic butterfly valve. Therefore, we must make the following pleadings for hydraulic oil.
1. The gasification of the hydraulic oil for the pneumatic butterfly valve of electric vehicles should be as small as possible. During the driving of electric vehicles, the hydraulic oil evaporates with the temperature rise. The hydraulic oil with small gasification makes the service life longer, the shock absorption effect better, and at the same time, it can meet various application environments and has a wide application range.
2. The freezing point of the hydraulic oil for the pneumatic butterfly valve of the electric vehicle is low, which can enable the electric vehicle to run normally in the cold climate in the north, and the common request is lower than - 40 ℃. At the same time, it has good viscosity index and viscosity temperature properties.
3. The shock absorption oil is clean. Clean hydraulic oil can reduce the wear of pneumatic butterfly valve, ensure the shock absorption effect, and improve its service life.
5. Pneumatic butterfly valve oil must have good working stability, oil gas mixing resistance and oxidation resistance stability.
Compensator, device and convenient transportation
The main body of non-metallic contraction joint adopts non-metallic materials, which greatly reduces the product weight, thus reducing the difficulty of device and transportation.
2. No hard force transmission
Non metallic shrink joint products are made of flexible materials, thus eliminating hard force transmission, optimizing the design of pipeline system, and extending the service life of pipeline equipment.
3. High resistance, temperature resistance, combustion and corrosion resistance
The non-metallic shrink joint is made of inorganic materials, so it has high temperature resistance and flame retardancy. And according to the different working media, we can select the corresponding data structure to deal with the corrosion problem.
4. Compensation device error
Systematic error is inevitable in the process of pipeline design, processing and installation. Non metal shrinkage can effectively eliminate these errors.
5. Good cost performance
The price of non-metallic shrink joints is far lower than that of metal bellows, and it is also 1/4~1/5 of the price of imported shrink joints.
6. Compensated thermal shrinkage
The pipeline system will have multi-directional deviation with the rapid change of temperature during operation. Non metallic shrinkage energy saving provides all-round compensation in a small space.
