In industrial production and daily life, manual metal-sealed gate valve with its unique structure, excellent performance and a wide range of applications play a pivotal role.
Key words: metal-sealed gate valve; manual gate valve;hard sealed gate valve;
First, the structure of manual metal-sealed gate valve
Manual copper seal gate valve is mainly composed of valve body, gate, sealing device, gasket, transmission mechanism and other major components.
The valve body, as the main body of the channel, is usually made of cast iron, ductile iron and other high-strength materials to adapt to a variety of complex working environments. The gate, as the core component to control the fluid flow, is made of high-quality copper to ensure that it still maintains good sealing and wear resistance under prolonged use.
Second, the characteristics of manual metal-sealed gate valve
- A. Good sealing: the use of copper sealing structure to ensure that the valve in the closed state without leakage, to meet the high sealing requirements.
- B. High temperature and corrosion resistance: copper material has excellent high temperature and corrosion resistance, suitable for a variety of harsh working conditions.
- C. Easy operation: the valve can be opened and closed by the handle, easy and fast operation.
Compact structure: the overall design is compact and reasonable, occupies little space, easy to install and maintain.
D. Long service life: the selection of high-quality materials, coupled with a reasonable structural design, making the manual copper-sealed gate valve has a long service life.
Third, the field of application
Manual metal-sealed gate valve is widely used in petroleum, chemical, metallurgy, electric power, urban water supply and drainage and other fields. In the petrochemical industry, it is used to control the transmission of crude oil, refined oil and chemical products; in the metallurgical industry, it is used for blast furnace, converter and other equipment cooling water system; in the urban water supply and drainage system, it is one of the indispensable and important equipment for controlling the supply and discharge of tap water.
Conclusion
With the progress of science and technology and industrial development, the performance of manual metal-sealed gate valve will be continuously improved and perfected to provide more reliable and efficient solutions for fluid control in various industries.
