喷气织机辅助压力调节用辅喷阀

Air jet loom auxiliary pressure adjusts and uses auxiliary spraying valve

Abstract

The utility model relates to an air jet loom auxiliary pressure adjusts and uses auxiliary spraying valve. Its characterized in that includes valve body and plunger, is provided with low voltage inlet, high -pressure air inflow mouth, gas outlet, plunger chamber, first solenoid valve, second solenoid valve, first gas circuit, second gas circuit, first recess and second recess on the valve body. The utility model discloses use with the cooperation of main injection valve, when weaving the woof of high number of yarn, low pressure owner injection valve opens, and the low pressure main burner drives the high grade cotton yarn wefting insertion, assists injection valve's low air pressure passage switch -on simultaneously, and steady wefting insertion is realized to the auxiliary spraying mouth under low pressure, reduce weft break and save the air supply, when the woof of weaving low number of yarn, high -pressure main injection valve opens, and high -pressure main burner drives the low grade cotton yarn wefting insertion, assists injection valve's high atmospheric pressure passageway switch -on simultaneously, and steady wefting insertion is realized to thick yarn under auxiliary spraying mouth pressure, avoid appearing the circumstances such as weft break. Two kinds of yarns prop up the 70 times of left and right sides that differ.
本实用新型涉及一种喷气织机辅助压力调节用辅喷阀。其特征在于包括阀体和柱塞,阀体上设置有低压进气口、高压进气口、出气口、柱塞腔、第一电磁阀、第二电磁阀、第一气路、第二气路、第一凹槽和第二凹槽。本实用新型与主喷阀配合使用,在织造高支数的纬纱时,低压主喷阀打开,低压主喷嘴带动高支纱引纬,同时辅喷阀的低气压通道接通,辅喷嘴在低压下实现平稳引纬,减少断纬和节省气源;在织造低支数的纬纱时,高压主喷阀打开,高压主喷嘴带动低支纱引纬,同时辅喷阀的高气压通道接通,粗的纱线在辅喷嘴压力下实现平稳引纬,避免出现断纬等情况。两种纱支相差70倍左右。
