The Development Speed Of Fluorine-lined Stop Valve

At present, the development speed of Lined Diaphragm Valve is very fast, and its development direction is high-end, which is also for market demand. So what is the specific situation?

China's valve manufacturing industry is facing the huge challenge of transforming to high-end, taking on international advanced manufacturing and participating in international division of labor. Accelerating the research, development and production of industrial intelligent technology is the main way for China to seize this historical opportunity. Therefore, the development of my country's valve industry should be further implemented: First, industrial intelligent technology is the main means and way for my country to transform from a manufacturing power to a manufacturing power. The government should have more policy and economic support for domestic industrial intelligence, refer to foreign advanced experience, and increase technical investment and transformation; second, in the national science and technology development plan, it should continue to give strong support to intelligent research, development and application, and form a new situation of synchronous coordination between products and automated manufacturing equipment; third, the intelligent quality of pneumatic and electric valves in the valve industry is already comparable to that of foreign countries. When enterprises purchase intelligent valves, they should not blindly import them. They should make comprehensive assessments, base themselves on domestic products, and revitalize domestic products.

Fluorine-lined stop valves are forced sealing valves, so when the valve is closed, pressure must be applied to the valve disc to force the sealing surface to not leak. When the medium enters the valve body from below the valve disc, the resistance that the operating force needs to overcome is the friction between the valve stem and the packing and the thrust generated by the pressure of the medium. The force to close the valve is greater than the force to open the valve, so the diameter of the valve stem should be larger, otherwise the valve stem will bend. In recent years, since the emergence of self-sealing valves, the medium flow direction of the stop valve has been changed to enter the valve cavity from above the valve disc. At this time, under the action of the medium pressure, the force to close the valve is small, while the force to open the valve is large, and the diameter of the valve stem can be reduced accordingly. At the same time, under the action of the medium, this type of valve is also more tight. my country's valve "three-in-one" has stipulated that the flow direction of the stop valve should be from top to bottom.
