First, product overview
X43F46 village fluorine plug valve is suitable for all kinds of concentrations of aqua royalty, sulfuric acid, hydrochloric acid, hydrofluoric acid and various organic acids, strong acids, strong oxidant, FEP is also suitable for all kinds of concentrations of strong alkali organic solvents and other corrosive gases, liquid media pipeline use. X43F46 series fluorine lined plug valve structure is compact and reasonable, the body cavity space is small, reduce the medium retention, in addition, the special molding process, the sealing surface density is good, coupled with the herringbone PTFE packing combination, so that the valve to zero leakage; This series is designed for the automatic opening and closing control of all kinds of strong corrosive medium pipelines
Widely used in petroleum, chemical, dyeing, pesticide, acid and alkali manufacturing industries, is currently one of the ideal choice of anticorrosive valve equipment.
Second, product performance
The X43F46 fluorine lined plug valve is made of fluorine plastic F46(FEP), and the shell is made of investment precision casting. It has high strength and smooth appearance. The part in contact with liquid is all fluorine plastic, so it can be used in corrosive pipelines and pipelines of any concentration in the range of -50°C ~ 120°C for a long time. The plug body rotates with the stem to achieve opening and closing action. The plug valve body is a cylinder, and the valve body with a round hole surface to form a sealing pair. The plug valve is a kind of valve used early in history, its simple structure, quick switching, fluid resistance is small. Ordinary plug valve is sealed by the direct contact between the finished metal plug body and the valve body, so the sealing is poor, the opening and closing force is large, easy to wear, the X43F46 fluorine-lined plug valve produced by our factory is made of tetrafluoride material, the sealing is very good and not easy to wear, the use of a wide range of media.
Third, the working principle
The X43F46 fluorine-lined plug valve uses the plug body with a through hole as the opening and closing part of the valve. The plug body rotates with the stem to achieve opening and closing action. Small packless plug valves are also called "cocks". The plug body of the fluorine lined plug valve is a cone (also a cylinder), and the conical hole surface of the valve body to form a sealing pair. Fluorine lined plug valve is the earliest use of a valve, simple structure, quick switching, fluid resistance is small. Ordinary plug valve by finishing metal plug body and valve body direct contact to seal, so poor sealing, opening and closing force, easy to wear, usually can only be used for low not more than 1 mpa) and small diameter (less than 100 mm) occasions
Fourth, product advantages
1, suitable for frequent operation, opening and closing quickly, light.
2. Low fluid resistance.
3, simple structure, relatively small volume, light weight, easy maintenance.
4. Good sealing performance.
5, not limited by the installation direction, the flow of the medium can be arbitrary.
6, no vibration, low noise.
