AI Technical Summary
Technical Problem
After long-term use of the existing metal casting pump head, due to corrosion problems, the friction between the bolt and the nut increases, resulting in difficulty in disassembly and may even lead to leakage.
Method used
A metal casting pump head sealing device is designed. By setting a sealing ring between the bolt and the threaded barrel, a sealing space is formed to reduce the risk of corrosion of the bolt. The arc-shaped piece and the slot are arranged to improve the stability of the connection.
Benefits of technology
It effectively reduces the risk of bolt corrosion, simplifies the installation and disassembly process, improves the sealing effect, and avoids leakage.

Abstract
The utility model belongs to the technical field of metal casting pump heads, and particularly relates to a metal casting pump head sealing device which comprises a pump head. First flange plates are respectively mounted at two ends of the pump head; one side of the first flange plate is connected with a second flange plate through a bolt, and one side of the second flange plate is provided with a connecting pipe; one side of the first flange plate is fixedly connected with a plurality of groups of protective cylinders; the cover plate can achieve the effect of sealing one end of the protective cylinder through the sealing ring, so that the whole bolt head is located in a sealed space, threads in the threaded cylinder can play a role of a nut, meanwhile, the effect of sealing the bolt rod is achieved, and the whole bolt can be located in the sealed space through the arrangement; and the arc-shaped sheets are clamped with the clamping grooves, so that the phenomenon that the arc-shaped sheets are separated from the interior of the protective cylinder is reduced, and the stability of the arc-shaped sheets in the connection process of the cover plate and the protective cylinder is improved.
