Description

Technical Field

[0001] The invention relates to the technical field of air valves, and in particular to an FRP electric and manual sealing air valve. Background Art

[0002] Among the current materials, composite materials are widely used because of their light weight and high strength. Air valves are used to adjust the air volume. The materials of air valves currently used are generally carbon steel plates, galvanized plates, aluminum alloy plates, and stainless steel plates. For some specific occasions, general air valves are not suitable for long-term use and will corrode, affecting their service life. FRP air valves are corrosion-resistant, flexible in operation, low in noise, and small in leakage. They are suitable for various occasions, so FRP air valves will surely be widely used in more factories.

[0003] Ordinary air valves are easily corroded by some specific media and need to be frequently maintained and replaced, which is not conducive to cost saving. In addition, due to the extensive design, poor sealing and large air flow of traditional FRP air valves, they are not suitable for use in specific occasions such as the transportation of flammable, explosive and polluted gases. In addition, the opening and closing angles of traditional FRP air valves are not easy to control. Therefore, considering these factors, FRP electric and manual sealing air valves are specially proposed. Summary of the invention
