Soft-sealed plug valves are commonly used in harsh environments such as corrosive, highly toxic and highly hazardous media, where leakage is strictly prohibited, and where valve material does not contaminate the media. The valve body can be made of carbon steel, alloy steel and stainless steel according to the working medium.
As a professional hydraulic control valve manufacturer, today's first valve information summary:
Soft-sealed plug valves are commonly used in harsh environments such as corrosive, highly toxic and highly hazardous media, where leakage is strictly prohibited, and where valve material does not contaminate the media. The valve body can be made of carbon steel, alloy steel and stainless steel according to the working medium.
A. According to the use temperature and working medium, self-lubricating material bushings such as F4, F46, PVDF, PP, PO, PE, etc. can be used for lubrication. The sealing friction coefficient is small during the whole working process, the plug body is flexible, and the service life is long. .
B. Valve body inlet and outlet end window design and double channel groove seal ring structure. During the rotation process of the cock, the sealing ratio between the sealing pairs is gradually changed until it reaches the fully open or fully closed position, resulting in sufficient sealing. Compared with the pressure, the sealing pair reaches zero leakage.
C. Double groove sealing ring can not only make the bushing stable in the valve body, but also absorb the slight deformation caused by the temperature difference, and generate strong friction between the bushing and the cock, with automatic cleaning. The effect is to improve the service life of the sealing surface.
D. The unique reverse lip seal design on the top of the plunger adopts a combination of a soft sealing material diaphragm and a metal diaphragm and an adjusting gasket to adjust the sealing specific pressure between the sealing surfaces, so that the plug can be rotated flexibly and can be guaranteed. Sealing of the outlet end and the middle flange connection.
E. Suitable for high scouring gas-solids. Liquid solid phase medium. Such as PVC, urea, phthalic anhydride, caustic soda production equipment, or external leakage requires high medium, such as HF, phosgene and so on.
F. The medium can flow in both directions, the installation direction is not limited, online maintenance is realized, and the use is more convenient.
G. Unique design to prevent static electricity, safe fireproof and safe to use.
