Special plug valve for asphaltDetailed information:
Plug valve is used as a plug hole with the headstock, realize the closed valve plug through the rotation, has good sealing performance, long service life, and has the advantages of inlet end seal. There are two basic types of liner cock: X44 series three way plug valve and X43 series three way plug valve.
Plug valves overview
Plug valve structure is simple, quick switch, fluid resistance is small, angle travel operation fast. In case of emergency, it can connect or cut off the pipeline quickly. Compared with gate valve and stop valve, the operation is more flexible and the switch is more rapid. The plug valve is a plug with a through hole as the headstock, and the stopper rotates with the valve stem to realize the opening and closing action. Small no filler plug, also known as "hancock". The plug body of the plug valve is mostly a cone (and also a cylinder), and a sealing pair is formed by matching with the taper hole surface of the valve body.
Main advantages of plug valves
1, suitable for regular operation, quick and easy to open and close.
2, fluid resistance is small.
3, simple structure, relatively small volume, light weight, easy maintenance.
4, good sealing performance
5, the direction of the installation is not limited, the media flow direction can be arbitrary.
6, no vibration, small noise.
The working principle of plug valve
Plug valve: with the plug through the hole as the valve opening and closing parts. The stopper rotates with the valve stem to realize the action of opening and closing. Small no filler plug, also known as "hancock". The plug body of the plug valve is mostly a cone (also has a cylinder), with the cone hole surface of the valve body to form a sealing pair. Plug valve is the earliest use of a valve, the structure is simple, fast switching, fluid resistance is small.
First, plug valve structure features
1, plug valve import and export side window design for double seal ring groove, plug in the spinning process, the sealing pressure in the gradual change over the side, until it reaches the fully open or fully closed position, produce enough sealing pressure to achieve zero leakage sealing. 2, plug valve double seal ring grooves that can make the PTFE bushing secured to the valve body does not produce displacement, but also can absorb micro deformation caused by temperature variation bushing produced, wipe effect and between the Bush and the strong cocks, and improve the service life of the sealing face.
3, plug valve plug shaft using a PTFE diaphragm and O ring and adjusting gasket combination, that is to adjust the sealing surface between the sealing pressure, so that plug rotation flexible, but also to ensure that the inlet, outlet and middle flange connection seal.
4, the whole sealing process can be considered to be independent of the pressure inside the pipeline.
5, plug valve PTFE bush, according to the use of temperature and working medium using different materials filling, lubrication, long life.
Two, plug valves design specifications
Follow GB/T12240, API599, API6D standards
Three, drive mode:
Manual, worm gear drive, electric
