Ball Valve With A Circular Hole With A Hole For The Opening And Closing Pieces

Ningbo Fenfa Valve Co.,Ltd | Updated: Sep 22, 2017

Ball valve refers to the ball with a circular through the hole for the opening and closing parts, the ball with the stem to rotate, in order to achieve the opening and closing action of the valve. It can also be used for the regulation and control of the fluid. The hard seal V-type ball valve has a strong shearing force between the V-shaped ball and the metal seat of the surfacing carbide. It is especially suitable for the use of fiber, Materials and other media. The multi-ball valve in the pipeline not only can be flexible control of the media confluence, diversion, and flow of the switch, but also can turn off any channel and the other two channels connected. This type of valve in the pipeline should generally be installed horizontally. Ball valve classification: pneumatic ball valve, electric ball valve, manual ball valve.

Ball valve in the 20th century, 50 years, with the rapid development of science and technology, production technology and product structure of continuous improvement, in a short period of 40 years, has rapidly developed into a major valve class. In the western developed countries, the use of ball valves is increasing year by year. In China, ball valves are widely used in oil refining, long-distance pipeline, chemical, paper, pharmaceutical, water, electricity, municipal, steel and other industries. The national economy occupies a pivotal position. It has a rotation of 90 degrees of action, the plug body for the ball, a circular through hole or channel through its axis. The ball valve is mainly used in the pipeline to cut, distribute and change the direction of flow of the media, it only needs to rotate 90 degrees of operation and a small turning torque can be closed tight. Ball valve is most suitable for the switch, cut off the valve to use, V-type ball valve. In addition to the valve should pay attention to the pipeline parameters, should pay special attention to the use of environmental conditions, because the electric valve in the electric device is a mechanical and electrical equipment, its use of its use by the environment greatly affected. Normally, the electric ball valve, butterfly valve in the following environment to pay special attention.

China's valve industry chain many, but non-valve power. Overall, China has entered the ranks of the world's largest valve, but the quality of products from the point of view of our country from the valve power is still a long gap. Industry production concentration is low, high-end products supporting the valve research and development capacity is low, the valve industry manufacturing technology level is still low, the import and export trade deficit continues to expand. The next few years will be the high-speed shock phase of the valve industry, the direct impact of this high-speed shock is the result of the valve brand camp polarization trend of expansion. Is expected in the next few years can really survive in the market of the valve business is absolutely not so much. But the valve industry, this high-speed shock will bring a huge opportunity, the shock results will make the market more rational operation. High-end valve of the localization of the road "rough". The basic piece has become a constraint to China's manufacturing industry to the development of high-end short board, the second five during the government will continue to increase the high-end equipment parts of the localization efforts. Here we select the "implementation plan" mentioned in a number of key development sectors of the representative of the valve for the import substitution of the feasibility analysis. From the analysis we can see the sub-sectors of the valve import substitution feasibility is very different, high-end valves need more policy guidance and research support. Valve industry in the national economic development, as the preparation of an important part of the manufacturing sector, played a very important role. As the level of domestic valve manufacturing industry in China compared with the international advanced level is still a certain gap, a lot of high parameters, high temperature and high pressure, high-grade key valve has been dependent on imports, in order to promote the localization of the valve, issued in the State Council " Equipment manufacturing industry a number of opinions ", the relevant state departments in accordance with the state made major equipment made in the domestic requirements, has made a series of major deployment, led by the National Development and Reform Commission, China Machinery Industry Federation and China General Machinery Industry Association, The deployment of the development of major areas related to the valve of the localization of the program, and many times with the relevant departments to coordinate, and now the localization of the valve industry in the domestic industry has formed a consensus. Shanghai Fanggong Valve Manufacturing Co., Ltd. is a manufacturer of large-scale valve manufacturer with decades of history. It is the most authoritative and influential top valve manufacturer in the country. It is a large-scale specialized R & D, production, sales and service. Valve manufacturing company. Its products are cast iron, carbon steel, stainless steel, chrome molybdenum steel, alloy steel, babbitt, Monel, etc., according to user requirements to produce all kinds of special valves. Active use of international standards for product design; absorption of foreign excellent design structure; product testing, performance testing in strict accordance with international standards; absorption of foreign advanced production technology experience attention to new materials research and application; to understand the import of high-parameter valve products Technical parameters and working conditions, etc. is to speed up the localization process, to promote the valve products continue to update, the full realization of the valve of the only way.

With the accelerated pace of reorganization of the valve industry, the future industry will be the valve product quality and safety and product brand competition between the products to high technology, high parameters, strong corrosion resistance, high life direction, only through continuous technological innovation, development New products, technological transformation, in order to gradually improve the level of product technology to meet the domestic equipment supporting the full realization of the localization of the valve. China's valve manufacturing industry in a huge demand environment, will show a better development prospects. The main features of the ball valve is its own compact structure, suitable for water, solvents, acids and natural gas and other general working medium, but also for poor working conditions of the media, such as oxygen, hydrogen peroxide, methane and ethylene, in a wide range of industries Applications. Ball valve body can be integrated, it can be modular. Ball valve is not only simple structure, good sealing performance, but also in a certain range of nominal diameter smaller, light weight, less material consumption, installation size is small, and the driving torque is small, easy to operate, easy to achieve fast opening and closing, More than 10 years to develop one of the fastest varieties of valves. The ball valve is evolved from the plug valve, and its opening and closing parts as a sphere, the use of the ball around the axis of the valve rotation 90 ° to achieve the purpose of opening and closing. Ball valve in the pipeline is mainly used to cut, distribution and change the direction of media flow, designed to V-shaped opening of the ball valve also has a good flow adjustment function. Especially in the United States, Japan, Germany, France, Italy, West, Britain and other industrial developed countries, the use of a wide range of ball valves, the use of species and the number continues to expand, and high temperature, high pressure, large diameter, high sealing, Life, excellent regulation performance and the development of a multi-functional valve, its reliability and other performance indicators have reached a high level, and has been partially replaced gate valve, globe valve, throttle. With the technical progress of the ball valve, in the foreseeable short period of time, especially in the oil and gas pipelines, oil refining equipment and the nuclear industry will have a wider range of applications. In addition, in other industries in the large and medium diameter, low pressure field, the ball valve will also become one of the leading type of valve.
