Ball Valve Introduction To Application And Development

Ningbo Fenfa Valve Co.,Ltd | Updated: Oct 30, 2017

The use of ball valve has been rising year in, in China, the ball valve is widely used in petroleum refining, long-distance pipeline, chemical, papermaking, pharmaceutical, Water conservancy, electricity, municipal, steel and other industries, in the national economy occupies a pivotal position. It has a rotation of 90 degrees of action, the plug body as a sphere, there is circular through the hole or passage through its axis. Ball valve in the pipeline is mainly used to cut, allocate and change the direction of the flow of the medium, it only needs to rotate 90 degrees of operation and very small torque can be closed tight. Ball valve is most suitable for switch, cut-off valve use, V-type ball valve. In addition to the electric valve should pay attention to the piping parameters, should pay special attention to its use of environmental conditions, because the electric valve in the electric device is a mechanical and electrical equipment, its use of the state affected by its use of the environment is very large. Normally, the electric ball valve, butterfly valve in the following environment use to pay special attention.


China valve industry chain is numerous, but not valve power. Overall to see our country has entered the ranks of the world's largest valve, but from the product quality of our country is still a long distance from the valve power. The industry's production concentration is low, high-end products supporting the valve research and development capacity is low, the valve industry manufacturing technology is still low, import and export trade deficit has been expanding. The next few years will be the valve industry's high-speed concussion period, this high-speed shocks brought about by the direct consequences of the valve brand in the camp polarization trend of expansion. The number of valve companies that are expected to survive on the market in the next few years is definitely not so much. But this high-speed oscillation in the valve industry will bring huge opportunities, and the results of shocks will make markets more rational. High-end valve localization of the road is abnormal "bumpy." The basic piece has become the restricting of the manufacturing industry to the high-end development of the short board, 35 period of government will continue to increase the high-end equipment components of domestic strength. Here we choose the "Implementation plan" mentioned in several key development industry representative valves for import substitution feasibility analysis. From the analysis we can see that the various industries valves import alternative feasibility is very large, high-end valves need more policy guidance and research support. Valve industry plays a very important role in the development of national economy as an important part of the preparation of manufacturing industry. As China's domestic valve manufacturing level and the international advanced level is still a certain gap, a lot of high parameters, high temperature and high pressure, high pound key valve has been dependent on imports, in order to promote the localization of valves, the State Council issued on the accelerated revitalization of the equipment manufacturing industry, a number of views on According to the national requirements of the major equipment made by the State, the relevant departments have made a series of major deployments, and led by the National Development and Reform Commission, China Machinery Industry Federation and China General Machinery Industry Association, the deployment of the relevant field of major equipment of the valve localization program, and several times with the relevant departments, Now the valve domestically in the domestic valve industry has formed a consensus. Shanghai Fang-Gong Valve Manufacturing Co., Ltd. has decades of history of large-scale valve manufacturers, is the most authoritative and most influential of the top valve manufacturers, is a professional research and development, production, sales and service as one of the large valve manufacturing company. Its products are cast iron, carbon steel, stainless steel, chromium molybdenum steel, alloy steel, Babbitt alloy, Mongolia, can be produced according to user requirements of a variety of special valves. Actively adopt international standards for product design, absorbing foreign excellent design structure, product testing, performance testing in strict accordance with international standards, absorbing foreign advanced production technology experience to attach importance to the research and application of new materials; To understand the technical parameters and working conditions of the imported high parameter valve products is to speed up the nationalization process, The only way to realize the valve's localization is to promote the valve product to be continuously updated.

With the rapid pace of restructuring the valve industry, the future industry will be valve product quality safety and product brand competition between products to High-tech, high parameters, strong corrosion, high life direction development, only through continuous technological innovation, the development of new products, technical transformation, can gradually improve the technical level of products to meet domestic equipment supporting, Fully realize the localization of valves. China's valve manufacturing industry in a huge demand environment, will show a better development prospects. The main feature of the ball valve is its compact structure, suitable for water, solvents, acids and natural gas and other general working medium, but also suitable for poor working conditions of the medium, such as oxygen, hydrogen peroxide, methane and ethylene, in various industries have been widely used. The ball valve body can be a whole, or it can be combined. Ball valve is not only simple structure, good sealing performance, but also in a certain nominal diameter range of small, light weight, less material consumption, small installation size, and driving torque is small, easy to operate, easily to achieve rapid opening and closing, is the fastest development in recent more than 10 years, one of the valve varieties. The ball valve is evolved from the plug valve, its headstock as a sphere, the use of the ball around the stem axis rotation 90 ° to achieve the opening and closing purposes. The ball valve is mainly used for cutting, distributing and changing the direction of medium flow in the pipeline, and the ball valve designed into V-shaped opening has good flow regulation function. Especially in the United States, Japan, Germany, France, Italy, West, British and other industrialized countries, the use of ball valves is very wide, the use of varieties and the number continues to expand, and to high temperature, high pressure, large caliber, high sealing, long life, excellent regulation performance and one valve multi-function direction, its reliability and other performance indicators have reached a higher level, and has been partially replaced by gate valve, globe valves, throttle valve. With the technical progress of the ball valve, it will be widely used in the foreseeable short time, especially on the oil and gas pipelines, the refinery cracking devices and the nuclear industry. In addition, the ball valve will also be one of the leading valve types in the medium and low pressure areas of other industries.
