Fluorine lined ball valve uses a ball with a circular through-hole as the opening and closing element, and the ball rotates around the centerline of the valve body with the valve stem to achieve valve opening and closing. Adopting a special molding process to make the sealing surface dense and good, combined with V-shaped PTFE packing combination to achieve zero leakage of the valve; The sphere and valve stem are cast as one, eliminating the possibility of the valve stem bursting out of the pressure bearing part due to pressure changes, fundamentally ensuring safety during use; Adopting the all plastic lining process, it is resistant to strong corrosion from the medium. There are manual lined ball valves, worm gear rotating lined ball valves, pneumatic lined ball valves, electric lined ball valves, etc. according to the driving mode.
1、 Working principle and purpose of fluorine lined ball valve:
Fluorine lined ball valves are designed for opening and closing control of various highly corrosive medium pipelines. The inner cavity and ball of the fluorine lined ball valve are lined with corrosion-resistant and aging resistant polypropylene using high-pressure injection molding technologyFluoroethylene propylene (F46) has reliable corrosion resistance and sealing properties. Widely used in industrial sectors such as chemical, petroleum, metallurgy, and pharmaceuticals to achieve acidThe regulation or cutting off of strong corrosive media such as alkali has a significant effect in water treatment process control. It is currently one of the ideal choices for anti-corrosion valve equipment.The fluorine lined ball valve adopts a fluorine plastic lining, and the shell is made of investment casting precision casting with high strength and smooth appearance. The parts in contact with the liquid are all made of fluorine plastic, so it can withstand temperatures between -50 ℃ and 180 ℃Long term use within the scope for corrosive pipelines and pipeline operations at any concentration.
2、 Product features of fluorine lined ball valve:
1. The ball valve with fluoroplastic lining layer has chemical stability and can be used for any strong corrosive properties except for "molten alkali metals and elemental fluorine".
2. Adopting a full bore and floating ball structure, the valve can be closed without leakage throughout the entire pressure range, making it easier for the pipeline system to pass through the ball and maintain the pipeline.
3. The opening and closing element ball is integrated with the valve stem cast (forged), eliminating the possibility of the valve stem impacting the pressure bearing part due to pressure changes, fundamentally ensuring its use in engineering
Security.
4. The structure is compact and reasonable, with the smallest internal space of the valve body, reducing medium retention. In addition, the special molding process ensures good density of the sealing surface, and the herringbone ring PTFE filling is used
Material combination to achieve zero leakage of the valve.
5. Two piece and three piece structures can adapt to various pipeline systems and working conditions with different requirements. The three piece ball valve allows the main valve body to be separated from the two side valve bodies, achieving fast online operation
Quick replacement and repair.
3、 Structural characteristics of fluorine lined ball valve:
The lining ball valve structure consists of a full bore floating ball type (two-stage) and a full bore fixed ball type (three-stage), mainly used to cut off or connect corrosive media in pipelines, and can be used for
Regulation and control of fluids,Compared with other valve types, it has the following characteristics:
1. The lined ball valve has low fluid resistance, smooth inner walls, and unobstructed flow channels, making it the valve with the lowest fluid resistance among all types of valves.
2. The switch is quick and convenient, simply rotate the sphere 90 ° to complete the account opening and closing actions.
3. Using a special molding process, the lining material is lined on the inner wall of the valve housing, which can withstand corrosion from strong acid and alkali media. The combination of lined spherical surface and PTFE valve seat has good sealing performance, achieving
Reached zero leakage.
4. Multiple drive devices such as pneumatic, electric, and hydraulic can be configured to achieve remote control and automated operation.
5. The sphere is integrated with the valve stem, eliminating the difference in rotation angle and eliminating the danger of the valve stem bursting out of the body due to pressure changes, ensuring the safety and reliability of use.
