Characteristics of oxygen valve: main features  1. The valve is mainly composed of valve body, valve cover, valve flap and other parts, which form a spherical valve body with uniform force. 2. The valve is manually operated. Turn the handwheel clockwise to close the valve, and turn the handwheel counterclockwise to open the valve. 3. For large-diameter valves such as ball bearings below DN50, DN150, DN200, DN300, etc., additional auxiliary flaps are added. The medium flows from the upper part of the valve flap to the lower part. 4. In order to achieve good sealing performance, the valve design is guided by the movement of the valve flap so that it can accurately fall on the valve seat. When the valve flap is guided in the valve body, the valve flap is driven by the lateral force of the flowing medium It is borne by the valve body instead of the valve stem, which further increases the sealing performance and the possibility of packing sealing. 5. The valve stem is designed as a descending rod, that is, when the valve stem does not rotate when the valve stem is raised and lowered, the valve flap moves up and down with it, which reduces the friction between the valve flap and the valve seat during movement, reduces the wear of the packing, and the upper seal wear may also Reduce to the minimum. 6. A grounding bolt is provided on the end flange of the valve body to be connected with a wire and a bolt to avoid explosion caused by static electricity. The exposed part of the valve stem has protective measures to prevent dust and oil. The bearing of the bracket is fluorinated grease, and the plexiglass cover plate is installed at the frame of the bracket, and there is an obvious "oil-free" mark to remind the personnel on site.
