The channel form of soft sealing plug valve has the common straight-through type, which is mainly used to cut off the fluid, and the three-way and four-way plug valves are suitable for fluid reversal.
Soft sealing plug valves are often used in harsh environments such as corrosive, highly toxic and highly hazardous media, where leakage is strictly prohibited, and where the valve material will not pollute the medium. The valve body can be made of carbon steel, alloy steel and stainless steel according to the working medium.
A. The unique design prevents static electricity, is safe from fire and is safe to use.
b. The medium can flow in both directions, the installation direction is not restricted, online maintenance is realized, and the use is more convenient
C. The double groove sealing ring can not only make the bushing stable in the valve body without displacement, but also absorb the slight deformation of the bushing caused by the change of temperature difference, and at the same time generate strong friction between the bushing and the cock, with automatic cleaning It can improve the service life of the sealing surface.
D. The unique reverse lip seal design on the top of the plunger adopts a soft sealing material diaphragm, metal diaphragm and adjustment gasket to adjust the sealing pressure between the sealing surfaces, make the plug rotate flexibly, and ensure that the Sealing of the outlet end and the mid-flange connection end.
E. Suitable for high scour gas-solids. liquid-solid medium. Such as PVC, urea, this anhydride, caustic soda production equipment, or external leakage requires high medium, such as HF, phosgene, etc.
F. The design of the window at the inlet and outlet of the valve body and the structure of the double groove sealing ring. During the rotation of the cock, the sealing pressure between the sealing pairs changes gradually until it reaches the fully open or fully closed position, generating sufficient sealing pressure. , the sealing pair achieves zero leakage.
G. According to the operating temperature and working medium, F4, F46, PVDF, PP, PO, PE and other self-lubricating material bushings can be used. The lubrication is good, the friction coefficient of the sealing pair is small during the whole working process, the plug body operates flexibly, and the service life is long.
