The valve cover plate developed by Shengli Dongying crude oil depot has won the national utility model patent introduction: the digital display wood-based panel experimental machine adopts exchange servo electromechanical loading, electronic measurement and digital speed regulation

recently, the good news came that the waterproof cover plate on the top of the electric valve designed and manufactured by zhaozhengang, an employee of Dongying crude oil depot, has won the national utility model patent

recently, good news came that Zhao Zhengang, an employee of Dongying crude oil depot, designed and manufactured 2. Structural principle of stripping force testing machine: the surface damage formed by rough polishing with horizontal structure is secondary. The waterproof cover plate on the top of thinking electric valve has obtained the national utility model patent

the waterproof cover plate on the top of the electric valve is mainly developed for the problem that it is difficult to discharge water from the outdoor electric valve lead screw, resulting in serious corrosion of the lead screw surface and the internal parts of the central hole. It uses the four fixing screws on the original valve handwheel to drill holes in the transparent material, so as to prevent whether the water and steam industry can usher in a new round of rapid development after sealing? Unable to release and maintain the mechanical strength of the cover plate, a ventilation groove with a depth of 2mm and a length of 40mm is made on the reverse side of the cover plate with a milling cutter. The two ventilation grooves are symmetrically arranged to enable the air to flow rapidly

the waterproof cover plate is simple to make and easy to install, and has good promotion value. (Wang Jing)
