Pneumatic butterfly valve can be designed with flange connection and clamping connection Source: Sansheng Trap Valve Time: 2020-01-13 Clicks:
Pneumatic butterfly valve consists of pneumatic actuator and butterfly valve. Pneumatic butterfly valve is a pneumatic valve that uses a circular butterfly plate that rotates with the valve stem to open and close to achieve the opening action. It is mainly used as a shut-off valve, or it can be designed to have a regulating function, or both. At present, butterfly valves are increasingly used in low-pressure large and medium-caliber pipes. Pneumatic butterfly valve classification: stainless steel pneumatic butterfly valve, hard seal pneumatic butterfly valve soft seal pneumatic butterfly valve carbon steel pneumatic butterfly valve main advantages of pneumatic butterfly valve simple structure, small size, light weight, low cost. This feature is particularly remarkable for pneumatic butterfly valves. It is installed in a high-altitude tunnel, and is controlled by a two-position five-way solenoid valve. The operation is simple and the flow medium can be adjusted.
Features:
1, compact and lightweight, easy to assemble, disassemble and repair, can be installed in any position.
2, simple and compact structure, low operating torque, 90 °; fast rotation to open
3. The flow characteristics tend to be straight, and the adjustment performance is good
4. The disc is connected to the valve stem in a pinless structure, overcoming possible internal leakage points.
5. The outer circle of the butterfly plate is spherical, which improves the sealing performance and prolongs the service life of the valve. The valve can be opened and closed more than 50,000 times under pressure and still maintains zero leakage.
6. The seal can be replaced, the seal is reliable, and the two-way seal is realized.
7. The butterfly plate can be coated according to user requirements, such as nylon or Teflon
8. The valve can be designed as flange connection and clamping connection
9. The drive mode can be manual, electric or pneumatic.
Powder system:
In the pneumatic butterfly valve powder system, there are other factors that need to be considered, such as: when the material is put into the car from above, it cannot directly rush to the valve plate (this impact force can also prevent the valve from closing tightly), and the static pressure of the material does not need to exceed Designed to carry pressure pneumatic butterfly valves, etc.
The difference between a control valve and an ordinary manual valve is that it cannot be considered as an isolated component, but must be considered as part of the entire automatic control system. Many problems in the use of control valves are not a matter of type selection and configuration, but because of insufficient user understanding of the control valves, the control valves cannot be debugged and cooperate well with the control system. As long as the key to the problem is recognized, the correct selection of the valve and the correct adjustment of the control valve during the system commissioning phase can greatly reduce the failure rate and the automatic control system can run stably for a long time.
