Problems solved by technology

In the process of manufacturing parts of this structure, due to problems such as the selection of glue grades and glue quality, whether the glue coating is in place, and whether the parts to be bonded are clean, there will be some ceramics due to water immersion during use. The debonding of the structural parts and the stainless steel axis caused the misalignment between the axis of the stainless steel water diversion valve and the water hole on the ceramic tube, which resulted in the high-pressure water flow not being supplied to the spray needle group normally, resulting in the shutdown of the loom

Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0013] The water diversion valve core of the water jet loom includes a water diversion shaft 1 and a water diversion jacket 2, the water diversion shaft 1 is fixedly arranged in the water diversion jacket 2, and the water diversion shaft and the water diversion jacket are respectively provided with holes 12 connected to each other . The axial side of the water distribution shaft 1 is provided with a first limiting plane 11, and the inside of the water dividing sleeve is provided with a second limiting plane 21 opposite to the first limiting plane. The first limiting plane and the second limiting plane The contact connection prevents the water distribution shaft from rotating relative to the water distribution sleeve.

[0014] The ends of the first limiting plane 11 and the second limiting plane 21 are respectively provided with opposite limiting steps ...

Abstract

The invention relates to the field of water jet looms, in particular to a water distribution valve spool of a water jet loom. The water distribution valve spool comprises a water distribution shaft and a water distribution sleeve, the water distribution shaft is fixedly arranged in the water distribution sleeve, and holes communicated mutually are formed in the water distribution shaft and the water distribution sleeve respectively. Limiting planes are arranged between the water distribution shaft and the water distribution sleeve, so that the water distribution shaft and the water distribution sleeve are prevented from rotating relatively due to bonding failure, as a result of water supply instability; the water distribution valve spool is reliable and stable in structure, and the requirement on normal water supply of the water jet loom is met.

Description

technical field [0001] The invention relates to the field of water jet looms, in particular to a water diversion valve core of a water jet loom. Background technique [0002] The existing water diversion valve valve core of the water jet loom has the function of distributing high-pressure water into several nozzle waterways, thereby realizing the function of spraying when there are multiple weft yarn nozzle components on a loom. During the actual weaving production process of the water jet loom, the water used by the manufacturer to reduce the production cost is circulating water. Due to the long-term use of circulating water, impurities in the water, rust and various chemicals used for water treatment will be deposited on the hole wall and the outer surface of the ceramic structural parts of the water diversion valve when they flow through the water channel of the diverter valve. After a certain period of accumulation, these impurities will cause foreign matter such as sca...
