1results about How to "Realize centralized recycling" patented technology

This invention discloses a welding device for a one-way explosion-proof valve body, comprising an adjustment component, a welding component, and a welding surface finishing component. The adjustment component is used to adjust the position of the welding surface finishing, and the welding component is used for adjusting and welding the valve body. The welding component includes a fixed plate fixedly mounted on the top of a fixed base and a first sliding rod fixedly mounted on the fixed plate. The welding surface finishing component is used to pre-treat the welding surface of the valve body at the position where it is welded to the flange. The welding surface finishing component includes a mounting plate, a transverse partition fixedly mounted on one side of the mounting plate, and side plates fixedly mounted on both sides of the transverse partition. This invention uses a rotating annular finishing strip to clean the welding surface of the valve body and the flange. The annular finishing strip fits tightly with the welding surface of the valve body, effectively removing oxide layers, oil stains, and impurities from the welding surface, improving the weld bonding strength, and avoiding affecting the subsequent assembly and sealing performance of the valve body.
