Valves are one of the most important tools that can not be neglected in the actual operation of pipeline management.If according to its function, it can be divided into shut-off valve, check valve, regulating valve, etc. The most representative valve in shut-off valve is Butterfly valve, butterfly valve can be used to control air, water, steam, all kinds of corrosive media and other types of fluid flow for furnaces, gas, natural gas, etc. used to regulate and cut off the flow of media.
Actively explore and innovate domestic butterfly valve equipment still need to tackle hard on the road
According to industry sources, the butterfly valve spool is generally circular valve plate, which can be vertical axis along the axis of rotation.When the valve plate plane and the axis of the pipe is fully open; gate plane perpendicular to the axis of the tube, when Fully closed.Due to the small butterfly valve body length, flow resistance is small, compared with the gate valve and the closing valve, the price slightly higher.
The author learned that the butterfly valve started late in our country. In the 1930s, the United States invented the butterfly valve, which was promoted in our country only after the 1970s. Although China has many valve chains, it is not a valve power. According to the driving mode, the structure and the sealing surface Material classification can be divided into many types of butterfly valves, although the valve category, but most domestic enterprises choose foreign products, such as France Wei Lan valve, Germany Hanwei valve, the United States Boley valves.
On the whole, China's domestic valve manufacturing industry is still a gap compared with foreign countries, a lot of high-parameter, high temperature and pressure, high-level key valve has always been dependent on imports.China has entered the ranks of the world's valve power, However, product quality and technological content point of view, China is still a long way from the valve power gap.
It is understood that in 1983 Bole Valve main production series of ball valves and control series, including the three-piece, flanged, threaded, porous and V-type control valve, actuator and control system. Three years later, the company further expand the valve Category to begin production of butterfly valves, control systems and tee products for the process control and transportation industries, winning the market with its unique design, superior quality, superb manufacturing process, near-perfect operational reliability and complete after-sales service With reputation.
Compared to the domestic butterfly valve equipment, foreign products are indeed superior technology, but also can not 'long as others wish to destroy their prestige' in China's butterfly valve manufacturing enterprises under the tireless efforts of domestic butterfly valve equipment are constantly innovating and breakthroughs. Butterfly valve manufacturers to actively explore innovative modes, the implementation of the combination of industry, academia and research development of new models, and domestic and foreign research institutes and enterprises, technological innovation and research, developed for China's food processing enterprises, sewage treatment and other needs of the butterfly equipment.
I was informed that the center line flanged butterfly valve launched by Tianjin Tanggu Waters Tesla Valve is the latest patented product.According to the introduction of the enterprise staff, the product brings together many advantages of the centerline butt butterfly valve and eccentric flanged butterfly valve to fill two types of butterfly valves In addition, its design is novel, reasonable, unique structure, quick opening and closing, and sealing performance to achieve two-way seal zero leakage.
In addition, Jiangsu Suyi Valve has been devoting itself to the research and development of various electric and pneumatic control valves. The independently developed high vacuum butterfly valve has been widely used in the production process of various industrial sectors such as food, medicine, petroleum and chemical industry Control and remote control exchange.The valve body with a small flow resistance, the rated flow coefficient, excellent sealing performance and other advantages by the new and old customers of all ages.
Thus, China's butterfly valve equipment manufacturing enterprises are also constantly exploring innovation.With the continuous development of China's food, pharmaceutical, petroleum, chemical and other industries, domestic butterfly valve manufacturers also need to innovate research and development, and actively learn from foreign advanced technology to speed up the domestic valve The manufacturing industry is moving in the direction of a powerful nation.
