Advantages and uses of electric butterfly valves
Electric butterfly valve is a very common device for pipeline flow regulation, which has a wide range of uses and involves many fields, such as the regulation of water flow in the reservoir dam of a hydroelectric power plant, the flow regulation of industrial fluids in the factory, etc., and the following will take you to understand the characteristics, advantages and use of the electric butterfly valve.
1. Good sealing
After all, the role of the electric butterfly valve is used to adjust the fluid flow in time, and it is faced with high temperature and high pressure when working, so if the sealing is not good, it will lead to fluid leakage, and it is impossible to ensure the accurate adjustment of the flow. The electric butterfly valve has a special sealing system, so it has good sealing in the range of ultra-low temperature to high temperature, that is, the sealing of the electric butterfly valve is not affected by temperature, and the electric adjustment valve switch is very convenient.
2. Zero leakage
The most commendable is the tightness of the electric butterfly valve, the shaft diameter seal of the valve stem adopts a very sealed ring, the sealing ring is pressed by graphite, the sealing ring and the butterfly plate of the electric butterfly valve will not be stuck, so the sealing is quite good, zero leakage fire safety electric butterfly valve is the preferred choice of many customers.
3. Convenient adjustment and control
The electric butterfly valve is a device used to control the flow of fluid, in addition to transporting and regulating fluids, mud and other substances with a certain viscosity can also be transported, and the liquid accumulated in the pipeline is small, and the electric opening and closing is fast and easy.
There are many types of valves used in industry, but it takes a lot of effort to buy a truly satisfactory valve, electric butterfly valve has a wide range of applications, strong operability and excellent sealing, and is a type of industrial electric valve that is very widely used.
Advantages and uses of pneumatic butterfly valves
The pneumatic butterfly valve is composed of a pneumatic actuator and a 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 enabling action, mainly used as a shut-off valve, and can also be designed to have the function of adjusting or section valve and adjusting, and the butterfly valve is used more and more in low-pressure large and medium-diameter pipelines. Pneumatic butterfly valve classification: stainless steel pneumatic butterfly valve, hard seal pneumatic butterfly valve, soft seal pneumatic butterfly valve, carbon steel pneumatic butterfly valve. The main advantages of pneumatic butterfly valve, simple structure, small size, light weight, low cost, pneumatic butterfly valve is particularly significant, installed in the high-altitude dark channel, easy to operate through two-position five-way solenoid valve control, and can also adjust the flow medium.
There are other factors that need to be taken into account in the powder system of the pneumatic butterfly valve, such as: the material cannot be directly rushed to the valve plate of the valve when it is put into the trolley from above (this impact force will also make the valve unable to close tightly), and the static pressure of the material should not exceed the design pressure of the pneumatic butterfly valve, etc.
The difference between the control valve and the ordinary manual valve is that it can not be regarded as an isolated component, but must be considered as a part of the entire automatic control system, many problems in the use of the control valve are not the problem of selection and configuration, but because the user’s understanding of the control valve is insufficient, the control valve has not been debugged and coordinated with the control system. As long as we realize the key to the problem, select the valve correctly, and debug the control valve in the system debugging stage, we can greatly reduce the failure rate and make the automatic control system run stably for a long time.
