AI Technical Summary

Technical Problem

The diameter of the valve stem perforation in the existing valve sleeve is fixed, which has poor applicability and requires overall replacement. In addition, the maintenance cost is high after wear.

Method used

A mechanical valve sleeve with good adaptability is designed. The sleeve core is detachably connected to the limit seat, and the lower end of the sleeve core is threadedly connected to the internal threaded hole of the limit seat through an external thread ring. Combined with the fastening assembly, the sleeve core can be detachably replaced and stably connected.

Benefits of technology

The applicability of the valve sleeve is improved, the sleeve core can be replaced easily according to the valve stem size, the maintenance cost is reduced, and the connection stability is enhanced.

Abstract

The mechanical valve sleeve with the good adaptability comprises a sleeve core and a limiting seat, an inner threaded hole is formed in the middle of the outer surface of the upper end of the limiting seat, a fastening assembly is arranged on the upper portion of the limiting seat, and the fastening assembly comprises an annular groove, a compression spring, an annular block, a guide hole and a guide rod. A valve rod penetrating hole is formed in the middle of the outer surface of the upper end of the sleeve core, a limiting block is fixedly installed on the outer wall of the lower end of the sleeve core, and an outer threaded ring is arranged on the outer wall of the lower portion of the sleeve core. According to the mechanical valve sleeve with the good adaptability, the sleeve core is arranged, the sleeve core and the limiting base are detachably connected, the sleeve core with valve rod penetrating holes of different sizes can be replaced conveniently according to the type of a valve rod, the applicability is improved, the sleeve core and the limiting base are detachably connected, and when the valve rod penetrating holes are abraded, the valve rod penetrating holes can be replaced conveniently. The sleeve core can be replaced independently, and the later maintenance cost is reduced.
