Abstract

本实用新型涉及一种阀管,尤其是用于洗衣机的阀管,它由大阀管、小阀管和拉簧组成,拉簧位于小阀管内,小阀管内腔有一阶梯与拉簧接触,小阀管位于大阀管内腔中,大阀管的后部有一向内的凸起,该凸起与小阀管后端面对应,这样,可以满足二级行程牵引器的需求。

Description

复合型阀管
本实用新型涉及一种阀管,尤其是用于洗衣机的阀管。
现有洗衣机用阀管,参见图1,通常由阀管1和拉簧2组成,拉簧2通过连接臂3与牵引器4连接,阀管1内腔有一阶梯8,该阶梯8与拉簧2相接触,参见图2,这样当在牵引力F1作用下,拉簧带动阀管运动,阀管1离开密封面0,实现排水功能。这种结构的阀管适用于一级行程牵引器,而不能满足二级行程牵引器的需要。
本实用新型的目的在于提供一种满足二级行程牵引器需要的阀管。
本实用新型是这样实现的,它由大阀管、小阀管和拉簧组成,拉簧位于小阀管内,小阀管内腔有一阶梯与拉簧接触,小阀管位于大阀管内腔中,大阀管的后部有一圈向内的凸起,该凸起与小阀管后端面对应,通过此对应关系小阀管传递力给大阀管。
采用本实用新型,当一级牵引力作用时,小阀管被拉动,但未触及大阀管凸起面,因此大阀管不受力,未离开密封面,当二级牵引力作用时,小阀管后端面顶住大阀管凸起面,小阀管带动大阀管受力,此时脱离密封面,从而满足二级行程牵引器的需要。
下面结合附图对本实用新型作进一步说明。
图1为已有技术结构示意图;
图2为已有技术受力状态结构示意图;
图3为本实用新型结构示意图;
图4为本实用新型受力状态结构示意图一;
图5为本实用新型受力状态结构示意图二。
参见图3、4、5,本实用新型是由大阀管5、小阀管6和拉簧2组成,拉簧2位于小阀管6内,小阀管6内腔有一阶梯8与拉簧2接触,小阀管6有一后端面7,小阀管6位于大阀管5内腔中,大阀管5的后部有一向内的凸起9,该凸起9与小阀管后端面7对应,当一级牵引力F1作用时,通过阶梯8,小阀管6被拉动,而大阀管5不受力,未离开密封面0,洗衣机处于非排水状态;当二级牵引力F2作用时,通过后端面7和凸起9的接触,小阀管6带动大阀管受力,此时脱离密封面,洗衣机进入排水状态,从而满足二级行程牵引器的需要。
