Abstract

本实用新型公开了一种安全可靠的安全阀。它包括阀体,所述阀体内设有内泄组件与外泄组件,所述内泄组件包括顶杆、顶杆下方的顶杆座,顶杆外周依次设有内泄密封垫、弹簧底座、内泄小宝塔弹簧、内泄大宝塔弹簧,所述顶杆与调压帽相连接,所述顶杆座周边设有若干只凸台。本实用新型适用于管路系统中压力的调节。

Description

安全阀
技术领域
本实用新型涉及一种阀门,尤其涉及一种用于管路系统中具有压力恒定作用的安全阀。
背景技术
安全阀广泛用于管路系统,当系统内压力高于设定的压力时,通过手动或自动开启安全阀,即可达到泄压目的,安全阀由内泄组件与外泄组件组成,其中内泄组件包括顶杆、顶杆下方的顶杆座,顶杆外周依次设有内泄密封垫、弹簧底座、内泄小宝塔弹簧、内泄大宝塔弹簧,顶杆端部与调压帽相连接,由于普通安全阀中的顶杆座外周尺寸小于阀体内泄进水处内径尺寸,因而当发生顶杆与调压帽脱离时,顶杆座易进入管道系统中,因而产生顶杆座堵塞管路的安全隐患。
实用新型内容
本实用新型要解决的技术问题是提供一种安全可靠的安全阀。
为了解决上述技术问题,本实用新型是通过以下技术方案来实现的:
本实用新型包括阀体,所述阀体内设有内泄组件与外泄组件,所述内泄组件包括顶杆、顶杆下方的顶杆座,顶杆外周依次设有内泄密封垫、弹簧底座、内泄小宝塔弹簧、内泄大宝塔弹簧,顶杆端部与调压帽相连接,所述顶杆座周边设有若干只凸台。
由于本实用新型采用周边带有凸台的顶杆座,即使顶杆与调压帽脱离,也不会使顶杆座进入管路系统中,因而提高了可靠性。
附图说明
图1是本实用新型的结构示意图;
图2是图1中顶杆座的结构示意图。
具体实施方式
下面结合附图及具体实施方式对本实用新型作进一步详细的描述:
如图1、图2所示:本实用新型包括阀体1,阀体1内设有内泄组件与外泄组件,内泄组件包括顶杆2、顶杆2下方的顶杆座3,顶杆2外周依次设有内泄密封垫4、弹簧底座5、内泄小宝塔弹簧6、内泄大宝塔弹簧7,顶杆2端部与调压帽8固定连接,顶杆座3周边设有若干只凸台9,由于凸台9周边直径尺寸大于阀体1内泄进水处内径尺寸,因而在顶杆2与调压帽8脱离的情况下,顶杆座3也不会进入管路系统中。
