The butterfly valve is a valve widely used in industrial and pipe systems. It has the advantages of simple structure, easy operation, good sealing ability and large flow rate, but there are also some disadvantages. In this paper, the characteristics and advantages of the butterfly valve are introduced in detail.
The characteristics of the wafer butterfly valve
1. Simple structure: the structure of the butterfly valve is simple, mainly composed of valve body, valve plate, sealing ring, etc. Its structure is simple, easy to manufacture and repair, and it is a low-cost valve.
2. Easy to operate: the clip valve is installed by clip, which is easy to operate. During the switching process, the butterfly plate can be moved along the valve body without an additional driving mechanism. Therefore, there is no noise and wear during the switching process, and it has a long service life.
3. Good sealing: good sealing performance of the butterfly valve, the sealing ring made of rubber and other materials, can ensure good sealing performance.
4. Large flow rate: the circulation capacity of the butterfly valve is large, and it can withstand a large fluid pressure and flow rate. In the pipe system, the butterfly valve can be used to cut and connect the fluid, and also to regulate and control the flow.
But the wafer butterfly valve also have some disadvantages.
(1) Limited scope of application: the scope of application for the butterfly valve is limited, and it is not suitable for high temperature, high pressure, high viscosity, flammable and explosive and other special fluid pipeline system.
(2) Seal performance may be affected: after a long time of use, the sealing ring may wear or deformation, resulting in the decline of sealing performance.
(3) Large opening and closing force: due to the large circulation capacity of the butterfly valve, the opening and closing force is also large. For a smaller fluid flow, it may need greater force to open and close the valve.
(4) the butterfly valve is not suitable for installation in a place with vibration: the butterfly valve is not suitable for installation in a place with vibration, otherwise it will affect its sealing performance and service life.
To sum up, the butterfly valve has the advantages of simple structure, easy operation, good sealing, large flow, but there are also some disadvantages such as limited scope of application, sealing performance may be affected, large opening and closing force, and the butterfly valve is not suitable for installation in a place with vibration. In the process of use, it is necessary to choose the appropriate valves according to the actual requirements and working conditions, and regularly check and maintain the valves to ensure their normal operation and service life.
