X44T three-way copper plug valve
Other Products
I. Introduction:
The X44T three-way copper plug valve is applicable to urban construction, chemical industry, metallurgy, petroleum, pharmaceuticals, food, beverages, and environmental protection. The opening and closing part of the plug valve is a cylindrical body with a hole. The cylindrical body and the valve stem rotate around an axis perpendicular to the channel, thereby achieving the purpose of opening and closing the channel. It is mainly used for opening and closing media in pipelines and equipment. The main advantages of this valve: suitable for frequent operation, quick and light opening and closing. Low fluid resistance. Simple structure, relatively small volume, light weight, easy to maintain. Good sealing performance, not limited by installation direction, the flow direction of the medium can be arbitrary. No vibration, low noise. The X44T three-way copper plug valve is used for cutting off, connecting and diverting media, but sometimes it can also be used for throttling depending on the nature of application and the erosion resistance of the sealing surface. The channel of the plug valve has various forms. The common straight-through type is mainly used for cutting off fluid. Three-way plug valves and four-way plug valves are suitable for fluid reversing. The opening and closing part of the plug valve is a cylindrical body with a hole, which rotates around an axis perpendicular to the channel to achieve the purpose of opening and closing the channel.
II. Features:
1. The window design at the inlet and outlet ends of the valve body adopts a double-groove sealing ring structure. During the rotation of the plug, the sealing specific pressure between the sealing pairs gradually changes. Until reaching the fully open or fully closed position, sufficient sealing specific pressure is generated, and the sealing pair achieves zero leakage.
2. The double-groove sealing ring of the X43W two-way plug valve can not only keep the PTFE sleeve stable in the valve body without displacement, but also absorb the slight deformation of the sleeve caused by temperature difference changes. At the same time, a strong wiping effect is generated between the sleeve and the plug, which further improves the service life of the sealing surface.
3. The upper part of the plug valve stem adopts a combination of a PTFE diaphragm, an O-ring and an adjusting gasket, which can not only adjust the sealing specific pressure between the sealing surfaces to make the plug rotate flexibly, but also ensure the sealing of the inlet, outlet and middle flange connection ends.
4. The entire sealing process of the plug valve can be approximately considered to be independent of the pressure in the pipeline.
5. Inside the PTFE sleeve of the plug valve, fillers of different materials are used according to the operating temperature and working medium, ensuring good lubrication and long service life.
III. Matters needing attention in installation and maintenance:
1. Reserve space for the rotation of the valve handle.
2. It cannot be used for throttling.
3. Plug valves with transmission mechanisms should be installed upright.
