LEVER TYPE SWITCH VALVE

摘要

A lever type switch valve has a switch chamber with three sections in the axial direction including, two outlet cavities at two ends and an inlet cavity in the central section. The outer end of each outlet cavity in the axial direction has a slide section; an inner protruding ring is disposed between two ends of the inlet cavity and the outlet cavities; a spindle of dumbbell shape, the spindle is slidably coupled to the inner side of the switch chamber axially; the spindle has three sections in the axial direction that are two pistons at two ends and a flowing section in the central section; the piston has a big outer end and a small inner end. The outer ends of the pistons are slidably coupled to the slide section in sealing way, the axial length of the outlet cavity is larger than the axial direction of the piston.

1. A lever type switch valve, wherein comprising:
a switch chamber with three sections in the axial direction that are two outlet cavities at two ends and an inlet cavity in the central section; the outer end of each outlet cavity in the axial direction is disposed with a slide section; an inner protruding ring is respectively disposed between two ends of the inlet cavity and the outlet cavities; a spindle of dumbbell shape, the spindle is slidably coupled to the inner side of the switch chamber axially; the spindle has three sections in the axial direction that are two pistons at two ends and a flowing section in the central section; the piston has a big outer end and a small inner end; therein, the outer ends of the pistons are slidably coupled to the slide section in sealing way, the axial length of the outlet cavity is larger than the axial direction of the piston; the axial length of the flowing section is larger than the axial length of the inlet cavity, the flowing section passes through the inner protruding ring and having a flowing passage with the inner protruding ring; the inlet cavity is connected to an inlet; the outlet cavities are respectively connected to an outlet, one end of the spindle is movably coupled to one end of a lever by a movable element; when the inner end of the piston of one outlet cavity couples to the inner protruding ring at the corresponding side in sealing way, the waterway of the outlet cavity and the inlet cavity is closed; at the same time, the outlet cavity of the other side is connected to the inlet cavity by the waterway of the flowing section and the inner protruding ring.
