Supply X43X three-way stopcock valve Shanghai Valve Factory wholesale Chemical

Second, the Shanghai-way stopcock valve plug High Chemical Products: Soft seal plug passage many forms. Commonly used to cut straight through the main fluid. Three and four plug valves for liquids commutation. Plug the opening and closing member is a cylindrical hole, around the vertical axis of rotation in the channel, so as to achieve the purpose of opening and closing the channel. Soft sealing plug valves for opening and closing the main pipe and the device media. Third, the Shanghai high chemical valves soft sealing plug plug Applications: soft sealing plug valves commonly used in corrosive, toxic and highly hazardous media and other harsh environment, strict ban leak occasions, and valve material does not pollute the occasion of the medium is formed . Body can be carbon steel, alloy steel and stainless steel material according to the working medium. Fourth, the Shanghai soft sealing plug valve plug high chemical structural features: A. according to temperature and working medium using F4, F46, PVDF, PP, PO, PE and other self-lubricating material bushing, lubrication is good, in the whole course of their work Sealing friction coefficient is small, the plug body flexible operation, long service life. B. Body Importers side window design and dual-channel trench sealing ring structure, cocks during rotation, the seal between the sealing pressure than vice gradually change until it reaches the fully open or fully closed position, resulting in sufficient sealing than the pressure seal deputy achieve zero leakage. C. dual-channel trench sealing ring not only allows the liner securely displaced in the valve body, and can absorb trace deformation caused by temperature changes due to the generation of the bush, at the same time have a strong friction between the bush and cock, self-cleaning action to improve the life of the sealing surface. D. plunger at the top of a unique anti-lip seal design with a soft sealing material metal diaphragm with diaphragm and gasket combination of both can be adjusted to adjust the seal between the sealing surface than the pressure, so that the plug rotating flexible, and can ensure that the inlet, the outlet end and the end of the sealing flange. E. suitable for high-erosion gas-solid. Liquid-solid phase medium. Such as PVC, urea, this anhydride, caustic soda production plant, or the external leak demanding media, such as HF, phosgene and the like. F. bi-directional media flow, mounting direction unlimited online for maintenance, easier to use G. unique design prevents static electricity, fire safety, safety. 1, suitable for frequent operation, opening and closing fast, lightweight. 2, a small soft sealing plug valve fluid resistance. 3, simple structure, relatively small size, light weight, ease of maintenance. 4, good soft sealing plug valve sealing performance. 5, the flow direction restriction is not installed, the medium can be arbitrary. 6, no vibration, low noise.
