Description

Check valve for water-jet braiding machine

Technical Field

The utility model relates to the technical field of water-jet braiding equipment, in particular to a one-way valve for a water-jet braiding machine.

Background

The water jet loom is different from shuttle loom and other shuttleless loom in that the weft inserting mechanism carries weft yarn with water flow and drives the weft yarn to pass through shed in high speed by means of the friction force between high pressure water flow and yarn.

The existing movable valve is movable in the using process, a water-jet weaving machine can automatically stop due to various reasons in the working process, weft insertion can be disconnected, and the effect of a finished product can be influenced because only water can be discharged but weft yarns cannot be discharged.
