Abstract

一种伸缩蝶阀,它包括阀体,以及套装在阀体流道延长段内的伸缩节,其特征在于:在伸缩节与阀体流道延长段配合部分的外管壁上加工有至少两道用于安装密封圈的环槽。本实用新型的优点在于:结构简单合理,安装调整方便,密封可靠。

Description

一种伸缩蝶阀
本实用新型涉及伸缩式阀门,具体说是涉及一种伸缩蝶阀。
目前在管线上使用的伸缩式阀门的伸缩节与阀体流道延长段配合部分的密封问题主要是靠压装在阀体流道延长段端面上的密封圈来解决的。其安装过程如下:首先调整好距离,之后连接安装,最后再用压环将密封圈压紧。上述结构的伸缩蝶阀安装后常出现以下不足之处:①压环螺栓易锈死,给维修带来极大不便;②安装时调整难度较大,易产生泄漏;③用料量较大,且加工工时多。
本实用新型的目的就在于克服上述现有技术中的不足之处而提供一种结构更为合理,安装调整方便的伸缩蝶阀。
本实用新型的目的可采用以下措施来实现:
本实用新型的伸缩蝶阀包括阀体,以及套装在阀体流道延长段内的伸缩节,在伸缩节与阀体流道延长段配合部分的外管壁上加工有至少两道用于安装密封圈的环槽,两道密封圈分别安装密封环槽内。
本实用新型的优点在于:结构简单合理,安装调整方便,密封可靠。
本实用新型的图面说明如下:
图1是本实用新型的主视图。
图2是图1的A-A剖视图。
本实用新型以下将结合实施例(附图)作以详细的描述:
如图所示,本实用新型的伸缩蝶阀包括阀体(1),位于阀体流道内的阀板,以及套装在阀体流道延长段内的伸缩节(2),在伸缩节与阀体流道延长段配合部分的外管壁上加工有两道用于安装密封圈的环槽(3),两道密封圈分别安装密封环槽内。
