Lined fluorine cocks, full lining plug valves, steel lined PTFE plug use;
Fluorine plug valves are widely used in oil field mining, conveying and refining equipment, but also widely used in petrochemical, chemical, gas, natural gas, liquefied petroleum gas, HVAC industry and general industry.
Lining fluorine cock valves, lined plug valves, steel lined PTFE plug works:
Use a plug with a through hole as the opening and closing valve. Plug with the stem rotation, in order to achieve opening and closing movements. Small non-packing plug valve, also known as "Cork." Lining fluorine plug valve plug body mostly cones (also cylinder), and the valve body conical hole surface with the composition of the sealing pair. Fluoride plug valve is the first to use a valve, the structure is simple, fast switching, fluid resistance. Normal plug valve by finishing the metal plug body and the direct contact between the body to seal, so poor sealing, opening and closing force, easy to wear, usually only for low (not higher than 1 MPa) and small Caliber (less than 100 mm) of the occasion.
Lined fluorine plug valves, lined plug valves, steel lined PTFE plug valve advantages:
1, Lined fluorine cock for regular operation, opening and closing quickly, light;
2, lined with fluorine stopper valve fluid resistance is small;
3, Fluoride plug valve lined structure is simple, the relative small size, light weight, easy maintenance;
4, good sealing performance;
5, regardless of the installation direction, the flow of medium can be arbitrary;
6, no vibration, noise.
Stopcock access:
Fluoride plug valve channel there are many forms. Common straight-through is mainly used to cut off the fluid. Three-way stopcock and four-way stopcock Suitable for fluid commutated stopcock open and close the valve is a perforated cylinder, rotating about the axis perpendicular to the channel, so as to achieve the purpose of opening and closing channels.
Soft Seal Fluoride Plug Valve:
Soft seal lined with fluorine plug valves commonly used in harsh environments such as corrosive, high-risk media, strictly forbidden leak situations, and the valve material will not pollute the media occasions. The valve body can be selected according to the working medium carbon steel, alloy steel and stainless steel.
A. According to the use of temperature and working medium using F4, F46, PVDF, PP, PO, PE and other self-lubricating bushing material, good lubrication throughout the work of the Deputy Vice friction coefficient, plug body flexible operation, long service life .
B. The valve body inlet and outlet end window design and dual groove seal ring structure, the cock in the rotation process, the sealing pressure between the sealing pressure is gradually changing until it reaches full open or fully closed position, to produce adequate sealing Pressure than the seal to achieve zero leakage.
C. Dual groove seal ring can not only make the sleeve stable in the valve body does not produce displacement, but also absorb the temperature changes caused by the liner caused by micro deformation, while producing strong friction between the bushing and the cock, with automatic cleaning Role, improve the sealing surface of the service life.
D. plunger at the top of the unique anti-lip seal design, the use of a soft seal material diaphragm and the metal diaphragm and adjusting the gasket combination can both adjust the seal than the pressure between the sealing surface, so that plug rotation flexibility, but also to ensure that into, Seal the outlet and center flange connections.
E. Suitable for high erosion gas-solid. Liquid-solid media. Such as PVC, urea, acetic anhydride, caustic soda production facilities, or external media require high leakage, such as HF, phosgene and so on.
F. media can flow in both directions, the installation direction is unrestricted, to achieve online repair, more convenient to use
G. unique design to prevent static electricity, fire safety, safe to use.
