Abstract

本实用新型公开了一种双回路保险阀,包括阀体:阀体内部具有空腔,空腔内部中间安装有孔用挡圈,孔用挡圈两侧安装有活塞,活塞与空腔内壁之间安装有O形密封圈,活塞内安装有弹簧,活塞外端部安装有垫板;活塞外侧安装有螺塞,螺塞与空腔内壁之间安装有大O形密封圈。本实用新型通过在阀体内的空腔左右两侧安装成对的活塞、弹簧及螺塞的结构方式,能够随压力改变有效的开闭,实现调节压力的保护功能,其机械强度与密封度均大大增强,长期使用也不会出现问题。

Description

一种双回路保险阀
技术领域:
本实用新型涉及阀门装置。具体的说是一种双回路保险阀。 
背景技术:
保险阀是化工,水利,医药等行业常用设备,在管道或设备的压力达到一定数值时,保险阀能够自动打开或关闭,使压力不会超过安全范围,从而保护设备不受损坏。通常使用的压力保险阀均是在输入端无压力时可自动关闭并且在正常压力恢复后可继续保持关闭状态的失压自动关闭保险阀,它解决了现有阀门因疏忽未关闭而易于造成的流体意外泄漏的问题,可与普通输出阀门串接或直接组合成一体使用。 
但现有技术的保险阀其结构简单,长期使用容易导致密封性和机械性能下降,具有安全隐患,因此设想提供一种新的结构改善。 
发明内容:
本实用新型的目的是提供一种双回路保险阀,通过在阀体内的空腔左右两侧安装成对的活塞、弹簧及螺塞的结构方式,能够随压力改变有效的开闭,实现调节压力的保护功能,其机械强度与密封度均大大增强,长期使用也不会出现问题。 
本实用新型采用的技术方案为: 
一种双回路保险阀,包括阀体:阀体内部具有空腔,空腔内部中间安装有孔用挡圈,孔用挡圈两侧安装有活塞,活塞与空腔内壁之间安装有O形密封圈,活塞内安装有弹簧,活塞外端部安装有垫板;活塞外侧安装有螺塞,螺塞与空腔内壁之间安装有大O形密封圈。 
本实用新型的优点为: 
本实用新型通过在阀体内的空腔左右两侧安装成对的活塞、弹簧及螺塞的结构方式,能够随压力改变有效的开闭,实现调节压力的保护功能,其机械强度与密封度均大大增强,长期使用也不会出现问题。 
附图说明: 
图1为本实用新型结构示意图。 
具体实施方式:
一种双回路保险阀,包括阀体3:阀体3内部具有空腔,空腔内部中间安装有孔用挡圈5,孔用挡圈5两侧安装有活塞7,活塞7与空腔内壁之间安装有O形密封圈6,活塞7内安装有弹簧4,活塞7外端部安装有垫板8;活塞7外侧安装有螺塞1,螺塞1与空腔内壁之间安装有大O形密封圈2。
