The flow passage of the fluorine-lined globe valve
body is streamlined, so the fluid resistance is small, and it can be applied to corrosive and high-viscosity media. The closing of the diaphragm valve is achieved by compressing the elastic rubber diaphragm, so it has good sealing performance and small closing torque, and there is no leakage and leakage. Different body lining and diaphragm materials can be selected for various corrosive media at different temperatures. The fluorine-lined globe valve selects pneumatic actuators of different specifications according to different medium pressures and operating air source pressures to achieve ideal use results. Corresponding accessories can be configured as required to realize automatic control, remote control or flow control. The fluorine-lined diaphragm valve is not only simple in structure and good in sealing performance, but also small in volume, light in weight, low in material consumption, small in installation size, small in driving torque, easy to operate and easy to open and close quickly within a certain nominal pass range. , is one of the valve varieties that have developed rapidly in the past ten years. The fluorine-lined diaphragm valve is evolved from a plug valve. Its opening and closing part is a sphere, and the sphere is rotated 90° around the axis of the valve stem to achieve the purpose of opening and closing. The fluorine-lined diaphragm valve is 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 adjustment function. The main function of the fluorine-lined globe valve is to cut off. The globe valve cannot be opened and closed frequently. Frequent opening and closing will cause the globe valve to not close tightly and damage the sealing performance. In anti-corrosion materials, PTFE has unparalleled excellent performance, in addition to molten alkali metals, elemental fluorine and aromatic hydrocarbons, in various concentrations of hydrochloric acid, sulfuric acid, nitric acid, aqua regia, organic acid , strong oxidants, alternating concentrated and dilute acids, alternating alkalis and various organic solvents are all random reactions. Lining PTFE on the inner wall of the valve, lining the valve with fluorine can overcome the shortcoming of low strength of PTFE material. , and solve the problem of poor corrosion resistance and high cost of the valve body material. The structural design of the fluorine-lined globe valve The opening and closing parts are plunger-shaped valve discs. The sealing surface is in two types: plane and conical surface. The opening and closing stroke of the valve stem of the fluorine-lined globe valve is shorter than that of similar valves, so the cutting performance is stable and reliable. The change of the valve seat port is proportional to the stroke of the valve disc, which can be used at the same time. Adjust flow usage. Fluorine-lined globe valve is a special valve for shut-off and shut-off, which can be used for cutting, regulating, throttling and other industrial and mining purposes at the same time. With the rapid development of modern industry, the fluorine-lined globe valve and its various pipeline accessories have been rapidly applied and promoted in various fields such as petroleum, printing and dyeing, and chemical industry, showing strong vitality. Great attention and favor of engineering design units and construction units, fluorine-lined globe valve is a sunrise product with market potential.
