Fluorine-lined Globe Valves with Great Market Potential

2016-03-14

The fluorine lined globe valve is designed to rotate with the stem, and the valve plate is used as the opening and closing parts to realize the opening, closing and regulating of the valve. In recent years, the sealing performance of globe valves has been taken as the main index of evaluation, besides cutting off and closing in pipelines, and has been favored by the market.

With the rapid development of modern industry, fluorine-lined globe valves and their various pipeline accessories have been rapidly applied in printing and dyeing, petroleum, chemical industry and other fields, showing strong vitality. As the preferred project in engineering, they have attracted great attention and favor from engineering design units and construction units. They are sunrise products with great market potential.

Fluorine-lined globe valve has the dual functions of switch and flow regulation, which can easily open and close the air circuit without affecting the no-flow and ensure the repeatability of flow. Starting slowly reduces the impact of instantaneous pipeline pressure on the instrument.A damper is added, which greatly improves the service life of needle valves. The fluorine-lined cut-off valve is specially designed for controlling corrosive or strongly corrosive medium. The inner surface of the valve body is covered with various fluoroplastics which can be selected. It is suitable for different working temperatures and fluid pipelines. It has the characteristics of high strength and good corrosion resistance. The high-performance fluorine-lined cut-off valve is characterized by: the seat seal ring is composed of multi-layer stainless steel sheets on both sides of the soft T-shaped seal ring. Therefore, unlike the existing technology, the utility model does not install a soft or hard multi-layer sealing ring on the valve plate, but directly mounts the ring on the valve body, and adds a regulating ring between the pressure plate and the valve seat is an ideal two-way hard sealing method. The structure of fluorine lined globe valve effectively compensates the tolerance zone between sleeve and valve body and the elastic deformation of valve stem under medium pressure, and solves the sealing problem of valve in the process of two-way interchangeable medium transmission.


The sealing surface of the valve plate and the valve seat is an oblique conical structure, and the temperature-resistant and corrosion-resistant alloy material is welded on the inclined conical surface of the valve plate; the spring fixed between the adjusting ring pressing plates and the adjusting bolt assembly on the pressure plate are assembled. When in the countercurrent state, the seal between the valve plate and the valve seat of the fluorine-lined shutoff valve is pressed against the torque of the drive device to press the valve plate against the valve seat. It will replace the gate valve and the ball valve. With the increase of the pressure of the reverse medium, when the unit positive pressure between the valve plate and the valve seat is less than the medium pressure, the deformation of the spring of the adjusting ring after the load is loaded can compensate the tightness of the valve plate and the valve seat and the sealing surface. The pressure acts as an automatic compensation.


Fluorine-lined cut-off valve is one of the most widely used valves in the fluorine-lined valve. The fluorine-lined cut-off valve uses a lining of fluorine-lined plastic with a spherical sealing surface, and the silicone rubber gasket at the base of the valve seat adjusts the sealing of the valve. Performance; the valve is light in operation, tight sealing performance, long service life; it can be used for quick cutting or regulating flow. Fluorine-lined globe valves are suitable for applications requiring reliable sealing and good regulation characteristics. The valve body adopts split type, and the sealing of the valve shaft at the present end is controlled by the rotating base between the butterfly plate and the valve seat plus fluororubber, thereby achieving compact product structure, beautiful appearance, reasonable process and reliable performance. It is very convenient to ensure that the valve shaft is not in contact with the fluid medium in the cavity. It is very convenient to replace the valve shaft of the fluorine shut-off valve. The valve can be completed without removing the pipe.
