The plug valve in the asphalt mixing station is a closed piece or plunger-shaped rotary valve. By rotating 90 degrees, the channel port on the valve plug is the same as or separated from the channel port on the valve body to open or close. It is widely used. In oil field excavation, transportation and refining equipment, such valves are also needed in asphalt mixing plants.

The plug shape of the plug valve in an asphalt mixing station can be cylindrical or conical. In a cylindrical valve plug, the channel is generally rectangular; in a conical valve plug, the channel is trapezoidal. These shapes make the structure of the plug valve light, which is very suitable for blocking and connecting the medium and diverting the flow.
Since the movement between the sealing surfaces of the plug valve has a scrubbing effect, and it can completely avoid contact with the moving medium when fully open, it can generally also be used for media with suspended particles. In addition, another important feature of the plug valve is that it is easy to adapt to the multi-channel structure, so that one valve can obtain two, three, or even four different flow channels, which can simplify the configuration of the pipeline system and reduce the amount of valves As well as some connecting accessories needed in the equipment.
The plug valve of the asphalt mixing plant is suitable for frequent operations because it is quick and easy to open and close. It also exhibits low fluid resistance, simple structure, relatively small size, light weight, easy maintenance, good sealing performance, and no vibration. , low noise and other advantages.
When the plug valve is used in an asphalt mixing plant, it is not restricted by the installation direction, and the flow direction of the medium can be any, which further promotes its use in equipment. In addition, it can also be widely used in petrochemical industry, chemical industry, gas, natural gas, liquefied petroleum gas, HVAC industry and general industry.
