Abstract

液化气安全阀是由阀门(1)阀座(6)半球形阀芯 (3)、壳体(4)和拉簧(5)组成,阀门(1)为外宽内窄的 喇叭口,将本实用新型装在液化气调压器的输出口 内,当调压器输出压力正常,气体进入阀体尾端,通过 阀门输出,当调压器失控,或输出管道破损,前后产生 压差时,阀门关闭以达到防止液化气泄漏中毒和防止 火灾的目的。

Description

本实用新型是涉及液化气管路防止泄漏的安全装置。
在现有技术中,在使用液化气时,先打开调压器,液化气经过调压器通过管道输送给炉灶燃烧,使用液化气灶具,是现代家庭厨房的必备装置,但是这种液化气灶具一旦开关失灵,调压器失控或输送管道破损,液化气泄漏容易引起中毒或者火灾。
鉴于公知技术存在的问题,本实用新型的目的是提供一种液化气安全阀,将安全阀装在调压器的输出口内,一旦调压器失控,灶具开关失灵或管路破损造成前后压差,阀门就自动关闭,达到防止中毒和火灾的目的。
本实用新型是在壳体4内安装一个具有通气空隙的座阀6,拉簧5的一端拉住阀座6,另一端与半球形阀芯3的颈部连接,阀门1加工成外宽内窄的喇叭口,并在阀芯3的关闭位置的圆周安装一个橡胶密封圈,参见图1。当把本实用新型安装在调压器的输出口内,正常工作时,气体进入阀体,管内压力平衡,阀门在开启位置,当调压器失控,炉灶开关失灵或输气管道破损,管内产生压差,其压力在350m/m水柱以下即能自动关闭。
本实用新型与现有技术相比,能有效地防止因液化气的调压器,灶具开关或管道破损而造成的泄漏,避免发生人身中毒和火灾。
附图是本实用新型的剖视结构图。
附图1给出了本实用新型的实施例,壳体4由黄铜或不锈钢制成,阀座6加工成具有通气空隙并安装在壳体4的一端,拉簧5一端拉住阀座6,另一端与半球形阀芯3连接,阀座与阀芯用工程塑料制成,阀门1也用黄铜或不锈钢加工成外宽内窄的喇叭口安装在壳体的另一端,在阀门的关闭处圆周设有一个橡胶密封圈2。按本实用新型设计主题所制作的液化气安全阀,将其安装在液化气调压器的输出口内就能防止泄漏,保证安全。

Claims (2)
