The main advantages of plug valve are as follows:
1. Plug valve is used for frequent operation, which can be opened and closed quickly and easily.
2. The flow resistance of plug valve is small.
3. Plug valve has the advantages of simple structure, small volume, light weight and easy maintenance.
4. It is not limited by the installation direction, and the flow direction of the medium can be arbitrary.
5. No vibration and low noise.
Plug valve can be divided into straight through type, three-way type, four-way type and so on. The straight through type controls the medium flow on the straight pipe section, and the three-way and four-way types can be used to distribute the medium and change its flow direction.
The working principle of the plug valve is that the plug rotates around the center line of the valve body, and the corresponding relationship between the opening on the cock body and the opening at both ends of the valve body is used to achieve the purpose of opening and closing.
