Description

Anticreep formula bimetal cylinder liner Technical Field The utility model relates to the technical field of bimetal cylinder sleeves, in particular to an anti-drop bimetal cylinder sleeve. Background The cylinder sleeve inner cavity of the traditional high-pressure slurry pump or other pump valves adopts a cold-hot embedded double-layer metal structure. In the production practice process, the bimetallic inner lining in the inner cavity of the cylinder sleeve is easy to fall off due to the high-pressure reciprocating movement of the piston, thereby bringing trouble to production and use, shortening the service life, increasing the production cost and even causing production accidents. In order to solve the above problems, the prior Chinese patent with the publication number of CN2921371Y discloses an anti-drop bimetallic cylinder sleeve, which comprises an inner metal bushing and an outer metal sheath, wherein the inner metal bushing is assembled in the outer metal sheath through interference fit, an inner groove is processed on a body at the upper end or the upper and lower ends of the outer metal sheath, after the inner metal bushing is assembled in the inner groove, an inner clamp spring or a retainer ring is assembled in the inner groove processed on the body at the upper end or the upper and lower ends of the outer metal sheath, and an inner convex step is reserved at the lower end of the outer metal sheath without the inner clamp spring or the retainer ring. The inventor finds that at least the following problems exist in the technology, namely, the inner metal bushing is limited and fixed by adopting a mode of welding the retainer ring and the outer metal sheath, and the inner metal bushing can be limited and prevented from falling, but the retainer ring and the outer metal sheath are welded, so that after the inner metal bushing is worn after being used for a long time, the inner metal bushing is inconvenient to be independently disassembled and replaced, and the later maintenance cost is too high.
