Water jet braiding machine ceramic ball one-way valve

Abstract

The invention relates to a water jet braiding machine ceramic ball one-way valve. The water jet braiding machine ceramic ball one-way valve is characterized by comprising a valve body, a sealing balland a valve cover, the valve body is internally provided with a valve cavity, and the opening of the valve cavity is located at the top of the valve body; a hollow water inlet pipe is arranged at thecenter of the bottom of the valve body, the water inlet pipe is connected with the inner wall of the valve body through a connecting bracket, and external high-pressure water can enter the inner partof the valve cavity through the water inlet pipe; and the sealing ball is movably arranged in the valve cavity, the valve cover is fixedly connected to the top of the valve body, and the center of thevalve cover is provided with a water outlet hole which can be blocked by the sealing ball. The invention has simple structure, the water pressure supply during the operation of a machine is stable, so that the start-up efficiency of the water jet braiding machine is greatly improved, the yield of cloth quality is greatly improved, and the economic benefit is improved.

Description

technical field [0001] The invention relates to a water jet knitting machine accessory, in particular to a ceramic ball check valve for a water jet knitting machine, which belongs to the technical field of textile machinery. Background technique [0002] The water jet loom is a new type of shuttleless loom that appeared in the 1950s. Compared with the traditional shuttle loom and other new shuttleless looms, it has the advantages of high speed, high output, high quality, and high labor productivity. High, low machine material loss, low noise, low energy consumption and other advantages. Especially in the weaving of synthetic fiber filament fabrics, the process is unique and has more advantages, so it develops very rapidly and becomes one of the four major types of shuttleless looms (rapier, projectile, air jet, water jet). [0003] The key difference between water jet looms and shuttle looms and other shuttleless looms lies in the weft insertion mechanism, which carries the...

AI Technical Summary

Problems solved by technology

At present, most of the one-way valves on the market for electronic water replenishment are made of metal materials (stainless steel), which have a large friction coefficient and limited smoothness, which will lead to unstable water pressure supply and affect the start-up efficiency of the water jet knitting machine. Thus affecting the yield rate of cloth surface quality

Moreover, the metal check valve has poor wear resistance, and it is prone to water leakage when it works for a long time under high-pressure water conditions.
