The replacement and renewal of double flange pneumatic ball valve is also a big market. The appearance of the double flange pneumatic ball valve is undoubtedly a breakthrough of the thermal pipeline pneumatic valve products. It not only opens up a new field for the production of pneumatic valves, but more importantly, it not only solves the fatal weakness of the working medium thrust in the pipeline, but also solves the problems of the double flange pneumatic ball valve that the stress is too concentrated and the medium resistance is large. At present, each manufacturer of double flange pneumatic ball valve is committed to the electronic control technology and information technology software of double flange pneumatic ball valve. The technical innovation has made the double flange pneumatic ball valve have better performance, and the stability of raw material price has made the double flange pneumatic ball valve market rise. In addition, pipe fittings are also a big market. The recognition of pneumatic valves and new product development technologies by the market also contributes to the growth of the market.
In the future, pneumatic valves will be more widely used. The growth rate of pneumatic valve is faster than that of double flange pneumatic ball valve. The spherical pneumatic valve has a larger market than the double flange pneumatic valve because of its wide use and simple structure. The double flange pneumatic ball valve uses Pascal theory in fluid mechanics to skillfully use a dense annular steam chamber in design structure. This steam chamber has two annular pressure surfaces, one is the fixed end face of the steam chamber, and the other is the annular surface of the valve pipe shoulder enclosed in the steam chamber, which is movable with the valve pipe.
The area of the movable annular pressure surface is just equal to the cross-sectional area of the valve pipe. When the pneumatic valve works, under the action of the medium pressure, the pressure on the annular surface is equal to the pressure on the cross-sectional area of the valve pipe, but in the opposite direction, so the two pressures cancel each other. In this way, only the friction force of the pneumatic valve pressing the packing is considered in the design of the support, and the thrust on the fixed support caused by the pressure of the working medium is not calculated in the calculation of the thrust on the fixed support. Therefore, the fixed support is a load reducing support, which can save a lot of support materials as well as manpower and financial resources. China and the United States are major countries in pipeline engineering, so they are also major users of double flange pneumatic ball valves. The replacement of double flange pneumatic ball valve is also a big market. With the recovery of the world economy, the import and export of China's double flange pneumatic ball valve products have also increased. However, there is still a big gap between China and foreign manufacturers in high-end technology. In the future, product technology will become a bottleneck restricting the development of China's double flange pneumatic ball valve products. China is gradually becoming the world's largest processing plant, and the processing and manufacturing of double flange pneumatic ball valve products face greater development space. It can be seen that as long as enterprises can seize the opportunity, strengthen research and development capabilities, and constantly improve the scientific and technological content of products and product quality, they can take the initiative in the fierce market competition.
