Abstract

一种耐用自来水开关,由阀盖、阀杆、挡圈、密封 垫圈、阀瓣和阀体组成。阀瓣为酒杯状,上缘用阀盖 压在阀体上孔孔肩上。开关打开时,水从进水管经阀 瓣下腔进入出水管排出。其特点:一是久用不冒水, 使用寿命长,阀瓣用坏了,换一个可以再用。二是体 积小,结构紧凑、简单,制造容易,成本低。

Description

本实用新型涉及自来水开关的改进。
已有的自来水开关(即水嘴、截止阀等),有两个密封带,关闭时,靠阀芯下面的胶垫密封,打开时,水从进水管经阀芯室进入出水管排出,故阀芯室上面的阀盖与阀杆配合面又有一个密封带,但用过一段时间后,阀杆与阀盖螺绞磨损后,密封性变差,放水时,水就从这里冒出来,很快报废,不耐用。
本实用新型的目的在于提供一种久用也不冒水的耐用自来水开关。
本实用新型是采用下列方式来达到目的的,不用闷芯,而是采用酒杯状有弹性的塑胶制的阀瓣,阀瓣上周缘用阀盖压紧在阀体上孔孔肩上,下中部有一密封垫圈,垫圈下压或上升受阀杆控制,下压时开关关闭,上升时,开关即打开,水从进水管经阀瓣下腔进入出水管排出。阀瓣上腔是没有水的,故阀盖与阀杆螺纹配合面不需密封,用久了,也无水可冒出来,而达到耐用之目的。
本实用新型的特点:一是久用不冒水,使用寿命长,阀瓣用坏了,换一个又可再用;二是体积小,结构紧凑、简单,制造容易,成本低。
下面结合附图来说明实施例:
图1为本开关(水嘴)纵剖视图。
图2为本开关(截止阀)纵剖视图。
参照图1-2,本开关由阀盖(1)、阀杆(2)、挡圈(3)、密封垫圈(4)、阀瓣(5)和阀体(6)组成。阀杆(2)上部为圆盘或圆环,下端部为锥体,锥体之上有一环槽,安有挡圈(3),杆部下半部有螺绞,与阀盖(1)中心螺孔配合,阀瓣(5)为酒杯状,底部内周缘有一环槽,环槽里安有密封垫圈(4),阀瓣(5)上周缘用阀盖(1)压在阀体(6)上孔孔肩上。
