AI Technical Summary

Technical Problem

The existing piston-type multi-way valve has insufficient stability in the movement of its moving parts, which affects the switching accuracy and the wear rate of the sealing piston.

Method used

A first guide hole and a second guide hole are provided on the housing to form a dual-point cooperative guiding structure. The first connecting part of the moving component slides in the first guide hole and the second connecting part slides in the second guide hole, thereby enhancing the motion stability.

Benefits of technology

It improves the motion stability and switching accuracy of moving parts, reduces the wear rate of the sealing piston, extends the service life of the piston-type multi-way valve, and ensures the stability and reliability of the water softener's function switching.

Abstract

The utility model provides a piston type multi-way valve and a water softener, and the piston type multi-way valve comprises a shell which is provided with a cavity, a first guide hole and a second guide hole, and the first guide hole communicates with the cavity; the sealing piston is movably arranged in the cavity; the driving mechanism is arranged on the shell; and the movable part is provided with a first connecting part and a second connecting part, the first connecting part is slidably arranged in the first guide hole in a penetrating mode and connected with the sealing piston, the second connecting part is connected with the output end of the driving mechanism, and the second connecting part is slidably inserted in the second guide hole. The first guide hole and the second guide hole are formed in the shell, so that the first connecting part of the movable part slides in the first guide hole, the second connecting part of the movable part slides in the second guide hole, a double-point cooperative guide structure is formed, radial deflection of the movable part in long-distance reciprocating motion is effectively limited, and the service life of the movable part is prolonged. The linearity and stability of the motion trail are ensured, and the motion stability of the movable part is improved.
