Fluorine-lined Stop Valve Realizes Automatic Remote Control Or Flow Control
Lined Globe Valve The body flow channel is streamlined, so the fluid resistance is small, which can be applied to corrosive and high-viscosity media. The closure of the diaphragm valve is achieved by compressing the elastic rubber diaphragm, so it has good sealing performance and small closing torque, and no leakage and seepage. Different valve body linings and diaphragm materials can be selected to apply to various corrosive media at different temperatures. Fluorine-lined stop valves select pneumatic actuators of different specifications according to different medium pressures and operating air source pressures to achieve ideal use effects. Corresponding accessories can be configured as needed to achieve automatic control, remote control or flow control.
Fluorine-lined diaphragm valves are not only simple in structure and good in sealing performance, but also small in size, light in weight, low in material consumption, small in installation size within a certain nominal diameter range, and have small driving torque, simple operation, and easy to achieve rapid opening and closing. It is one of the fastest-growing valve varieties in the past decade. Fluorine-lined diaphragm valves evolved from plug valves. Its opening and closing parts are used as a sphere, and the sphere is rotated 90° around the axis of the valve stem to achieve the purpose of opening and closing. Fluorine-lined diaphragm valves are mainly used to cut off, distribute and change the flow direction of the medium on the pipeline. The ball valve designed with a V-shaped opening also has a good flow regulation function.
The main function of the fluorine-lined stop valve is to cut off. The stop valve cannot be opened and closed frequently. Frequent opening and closing will cause the stop valve to be loose and damage the sealing performance. Among the corrosion-resistant materials, polytetrafluoroethylene has incomparable excellent performance. In addition to molten alkali metals, elemental fluorine and aromatic hydrocarbons, it reacts randomly in various concentrations of hydrochloric acid, sulfuric acid, nitric acid, aqua regia, organic acids, strong oxidants, concentrated and dilute acid alternation, alkali alternation and various organic solvents. By lining the inner wall of the valve with polytetrafluoroethylene, the fluorine-lined stop valve overcomes the disadvantages of low strength of polytetrafluoroethylene materials and solves the shortcomings of poor corrosion resistance and high cost of the valve body material.
The structural design of the fluorine-lined stop valve is a plunger-shaped valve disc, and the sealing surface is a flat surface and a conical surface. The valve disc moves in a straight line along the center of the valve seat. The concealed stem is in motion, and the open stem is a lifting and rotating rod. The valve stem opening and closing stroke of the fluorine-lined stop valve is shorter than that of similar valves, so the cutting performance is stable and reliable. The change of the valve seat opening is proportional to the stroke of the valve disc, and it can be used to adjust the flow at the same time. The fluorine-lined stop valve is a special valve for shutoff and can be used for shutoff, regulation, throttling, etc. in industry and mining.
With the rapid development of modern industry, fluorine-lined stop valves and various pipeline accessories have been rapidly applied and promoted in various fields such as petroleum, printing and dyeing, and chemical industry, showing strong vitality. As the preferred project in the project, it has attracted great attention and favor from various engineering design units and construction units. The fluorine-lined stop valve is a sunrise product with market potential.
