Fluorine-butterfly plug valves, full lining plug valves, steel lining four fluorine cock purposes;

fluorine-butterfly plug valve widely used in oil field exploitation, transportation and refining equipment, but also widely used in petrochemical industry, chemical industry, coal gas, natural gas, liquefied petroleum gas, hvac industry and general industry.

fluorine-butterfly cock, lining plug valve, the working principle of steel lining four fluorine cock:

with hole plug body as the opening and closing of the valve. Plug with the valve rod rotation, in order to realize the opening and closing action. Small without filler plug valve is also known as ''. Fluorine-butterfly plug valve plug body for cone ( There are also the cylinder) , cooperate with the taper hole surface of the body composition of seal. Fluorine-butterfly plug valve is to use one of the first valve, simple structure, switch quickly, small fluid resistance. Ordinary cock on finishing the direct contact between the metal plug body and the body to seal, so the sealing is poorer, opening and closing force is big, easy to wear and tear, usually can only be used for low ( No more than 1 million mpa) And small diameter ( Less than 100 mm) The occasion.

fluorine-butterfly cock, lining plug valves and the advantages of steel lining four fluorine cock:

1, fluorine-butterfly plug valves used in operations, often open/close quickly, light;

2, fluorine-butterfly cock valve fluid resistance small,

3, fluorine-butterfly plug valves has simple structure, relatively small size, light weight, easy to maintenance;

4, sealed performance is good;

5, not limited by the installation direction, the flow of medium can be arbitrary;

6, no vibration, low noise.

cock channel:

fluorine-butterfly cock channel has a variety of forms. Common straight-through type is mainly used for cutting fluid. Three-way cock and cross plug Industrial Valves is suitable for the fluid directional control plug valve opening and closing is a hole in the cylinder, perpendicular to the axis of rotation of the channel, so as to achieve the aim of opening and closing the channel.

soft sealing fluorine-butterfly cock:

soft seal rubber fluorine plug valves used in corrosion resistance, high hazard medium, such as harsh environment, strictly banned leak, and valve material not medium formation pollution occasion. The body could be selected according to the working medium carbon steel, alloy steel and stainless steel materials.

A. Can be used according to the working temperature and medium with F4, F46, PVDF, self-lubricating material such as PP, PO, PE liner, good lubrication, sealing in the whole working process of the pair of small friction coefficient, the plug body flexible operation, long service life.

B。 Body import and export side window design and two-channel grooved ring structure, plug in the process of rotation, the seal between the sealing pressure ratio in the gradual change, until she reached full open or close position, generate enough sealing pressure, seal achieve zero leakage.

C。 Two-channel grooved ring can make solid liner in the body does not produce displacement, and can absorb trace deformation caused by temperature change bushing, between liner and cock at the same time produce strong friction, with automatic cleaning function, improve the service life of the sealing surface.

D。 Piston at the top of the unique design of the lip seal with a soft sealing material film and metal diaphragm and adjusting shim combination can adjust the seal between the sealing surface pressure, flexible to rotate the plug, and can assure you, in the outlet and the seal on flange connection.

E。 Suitable for high scouring of gas-solid. The liquid-solid phase medium. Urea, acetic anhydride, such as PVC, caustic soda production devices, or external leakage demanding medium, such as HF, phosgene, etc.

F。 Medium can be two-way flow, there is no limit on the installation direction, realize the online maintenance, use more convenient

G. Unique design can prevent static electricity, fire safety, use safety.
