Many high-pressure valves produced by some domestic enterprises have shortcomings such as external leakage and internal leakage, low appearance quality, short service life, inflexible operation, and unreliable electric valves and pneumatic valves. The future growth of the valve market is mainly in electric power, petrochemical, chemical fertilizer, Environmental protection and other fields, for valve companies, who has good technology and excellent quality, who can continue to develop new products, who will be able to seize the opportunity in the fierce competition. To improve the quality of the valve, we must work hard on production management, technical level and new product development. First of all, we must strengthen management. Production and technical management should be in line with international standards as soon as possible, speed up the adoption of international standards and advanced foreign standards, increase investment, introduce modern and automated equipment, and innovate existing products. At the same time, valve companies should take effective measures to select raw materials for castings and forgings, casting and forging processes, heat treatment and other aspects to make the internal quality and appearance of castings and forgings reach international levels. Secondly, we should vigorously develop new products with high technology content, focusing on the development of new valve products supporting the construction of major projects such as large-scale petrochemical industry, oil and gas gathering and transportation pipelines, coal liquefaction, etc. Secondly, we should strengthen the research on internal and external leakage of high-pressure valves, strictly machine processing technology, vigorously develop and promote new sealing materials, improve the processing accuracy of key parts of products, and prolong the service life of products, So that the valve "one short and two leakage" phenomenon has been fundamentally improved.

High-pressure valves are indispensable fluid control equipment for various sectors of the national economy, such as petroleum, chemical, power stations, long-distance pipelines, shipbuilding, nuclear industry, various low-temperature projects, aerospace and marine oil production. After years of development, the number of valve enterprises in China ranks first in the world, with more than 6000 valve enterprises of various sizes, of which 900 have an annual output value of more than 5 million yuan. Judging from the product situation, China's valve industry has been able to produce more than a dozen categories of products, such as high-pressure gate valves, pneumatic globe valves, high-pressure check valves, proportional pressure reducing valves, descaling valves, pneumatic cut-off valves, etc., with the highest operating temperature reaching 570 ℃ and the lowest

Gate valve: Gate valve refers to the valve that closes the valve (gate) along the vertical direction of the channel axis. It is mainly used as a cut-off medium in the pipeline, that is, fully open or fully closed. In general, the gate valve can not be used as a regulator flow. It can be applied to low temperature pressure can also be applied to high temperature and high pressure, and according to the different materials of the valve. But the gate valve is generally not used to transport mud and other media in the pipeline. Advantages: ①The fluid resistance is small; ②The torque required for opening and closing is small; ③It can be used on the ring network pipeline where the medium flows in two directions, that is to say, the flow direction of the medium is not restricted; ④When fully opened, the sealing surface is affected by the working medium

In the development of the national economy, the valve industry as an important part of the machinery and equipment manufacturing industry, has a very important role. Valves in the important areas of the national economy and people's livelihood, such as large-scale clean and high-efficiency power generation, ultra-supercritical thermal power, gas steam cycle, large ships, large chemical ships, aircraft carriers, CNG, atmospheric governance, urban industrial wastewater treatment, urban pipe network transformation and so on have a lot of demand. Therefore, China attaches great importance to the valve industry and is committed to building China into a major production base for global valves. During the "Eleventh Five-Year Plan" period, the National Development and Reform Commission and other relevant state departments proposed to "strive for the gradual realization of major equipment."
Installation and use of check valve

Straight-through lift check valve should be installed on the horizontal pipeline, vertical lift check valve and bottom valve are generally installed on the vertical pipeline, and the medium flows from bottom to top. Swing check valve installation position is not properly limited, usually installed in the horizontal pipeline, but can also be installed in the vertical pipeline or dumping pipe. When installing the check valve, special attention should be paid to the direction of the medium flow, and the direction of the normal flow of the medium should be consistent with the direction of the arrow indicated on the valve body, otherwise it will cut off the normal flow of the medium. The bottom valve should be installed at the bottom of the water pump suction pipe. When the check valve is closed, water hammer pressure will be generated in the pipeline, which will cause serious

Domestic policy and economic situation for the better, the pump industry and the valve industry have been favorable conditions for development, the rising space is also very huge. It is expected that there will be a big improvement in the next few years. In the next 5 years, the development direction of Sinopec pumps is large-scale, high-speed, mechatronics, and product integration, standardization, serialization and generalization. In particular, the production technology of high temperature pump, low temperature pump and ultra low temperature pump, precision metering pump, corrosion resistant pump, conveying viscous medium and medium pump with solid particles, shielding pump will develop rapidly, and the demand will increase greatly. China's valve industry from the beginning to date has been issued
