Today, I will introduce a common valve, that is, stainless steel ball valve. Introduce some working principles and some basic knowledge about stainless steel ball valves. The stainless steel ball valve rotates 90 degrees and closes securely with a small rotational torque. The completely equal valve body cavity has little resistance to the medium and provides a straight flow path. The main features of the ball valve are its compact structure, easy operation and easy repair. Stainless steel ball valves can be used to control the flow of various fluids such as air, water, steam, various corrosive media, muddy water, oil products, liquid metals and radioactive media. The valve body can be integral or combined. This valve is generally installed horizontally in the pipe. The working principle of stainless steel ball valve: turn the core of the valve to open and close the valve. The valve switch is light, small in size, can be made into a large diameter, reliable sealing, simple in structure, easy to repair, and the sealing surface and spherical surface are often in a closed state, which is not easy to be corroded by media, and is frequently used in various industries. Ball valves are mainly used to cut off, distribute and change the flow direction of the medium in the pipeline. The advantages of stainless steel ball valve: 1. The fluid resistance is small, and its resistivity is equal to the same length of the pipe section. 2. Simple structure, small size and light weight. 3. Tight and reliable, the ball valve sealing surface material is widely used in plastic and sealing. Vacuum systems are also widely used. 4. Easy to operate, open and close quickly, and rotate 90° from full open to full close, which is convenient for remote control. 5. It is easy to repair, the ball valve has a simple structure, and the sealing ring is generally movable. It is easy to disassemble and exchange. 6. When fully open or fully closed, the sealing surface of the ball and valve seat is isolated from the medium, and the medium will not cause erosion of the valve sealing surface when passing through. Maintenance method of stainless steel ball valve: 1. After the rough finished product, after pickling, it must be rinsed clean. If there are sand holes or perforations, it should be gas shielded by argon arc welding. It is then sanded and then solidified. 2. The finished product, after the processing and pressure test is completed. It should be rinsed with water with anti-rust powder added. 3. Use wooden boxes as much as possible during transportation and do not touch metal products. 4. After the pipeline is installed, it is regularly maintained and maintained, for example, the valve stem is often lubricated. Properly open and close the valve several times. So that the inner ball, valve stem and sealing surface are not easy to assimilate.
