Describe
American Standard Oxygen Globe Valve Product Overview
It is made of stainless steel made of American standard and has the advantages of high mechanical strength, wear resistance and good safety. Used in the oxygen pipeline, it has excellent explosion-proof flame retardant performance and eliminates the unsafe factors on the oxygen pipeline. Wenzhou Ruitong American standard oxygen shut-off valve is widely used in oxygen, steel, metallurgy, petrochemical, chemical and other oxygen engineering. In the pipe network. In addition to the function of a common valve, it has its own characteristics. Strict oil repellency measures are applied during manufacturing and all parts are subjected to a rigorous degreasing process prior to installation.
 
American standard oxygen special cut-off valve uses:
It is specially used in the oxygen pipeline network of iron and steel, metallurgy, medicine, chemical industry and petroleum industry. Oxygen special cut-off valve type product has reasonable structure, reliable sealing, excellent performance and beautiful appearance; Co-based hard alloy is welded on sealing surface, wear-resistant, corrosion-resistant, anti-friction performance and long service life.
Special shut-off valve for oxygen (Beijing type) is a special valve for oxygen pipeline. In addition to the characteristics of ordinary valves, it is also made of copper with excellent texture, corrosion resistance, good flame retardancy, good electrical conductivity and heat transfer. The advantages of fastness and other advantages, this series of products has become an ideal equipment in the oxygen management engineering system.
 
American standard oxygen shut-off valve features
1. The structure is simpler than the gate valve, and it is convenient to manufacture and maintain.
2. The sealing surface is not easy to be worn and scratched, and the sealing property is good. There is no relative sliding between the valve flap and the sealing surface of the valve body when opening and closing, so the wear and abrasion are not serious, the sealing performance is good, and the service life is long.
3. When opening and closing, the valve flap stroke is small, so the height of the shut-off valve is smaller than that of the gate valve, but the structure length is longer than the gate valve.
4, the opening and closing torque is large, the opening and closing is more laborious, the opening and closing time of the principal.
5, the fluid resistance is large, because the medium passage in the valve body is tortuous, the fluid resistance is large, and the power consumption is large.
6. Direction of medium flow When the nominal pressure PN ≤ 16MPa, the downstream flow is generally adopted, and the medium flows upward from the valve flap. When the nominal pressure PN ≥ 20MPa, the counterflow is generally used, and the medium flows downward from above the valve flap. To increase the sealability. When in use, the shut-off valve medium can only flow in one direction and cannot change the flow direction.
