Description

罐式集装箱外置式安全泄压阀
技术领域
本发明涉及一种泄压阀，特别是涉及一种罐式集装箱外置式安全泄压阀。
背景技术
现有的罐式集装箱外置式安全泄压阀，阀体内部设置单个弹簧安装空间大，只能通过减少罐箱的充装容积来保证罐箱标定体积，因而不经济；且阀瓣下端面设置U形的环形槽，U形的环形槽内的O型圈容易脱落，影响产品的使用寿命及移动罐箱的安全运输。
发明内容
为了克服现有罐式集装箱用泄压阀的上述缺点，本发明提供一种结构紧凑、安装空间小、密封性能好的罐式集装箱外置式安全泄压阀。
本发明解决其技术问题所采用的技术方案是罐式集装箱外置式安全泄压阀包括阀体，阀体上方固定连接阀盖，阀体下端口设置有BSP螺纹，阀体内腔设置有阀瓣，阀瓣与阀盖之间设置有弹簧，弹簧为弹簧组，阀瓣下端面开有Ω形环形槽，Ω形环形槽内嵌有包覆O型圈。
弹簧组由内弹簧和外弹簧组成。
包覆O型圈材料为由FEP聚合物包覆的橡胶弹性体。
本发明的有益效果如下：
本发明采用弹簧组结构，结构紧凑，安装空间小，在保证罐箱标定体积的范围内，可有效增大罐箱的充装容积，提高运输效率，节约成本；且在阀瓣下端面设置Ω形环形槽，Ω形环形槽内嵌入O型圈，使得O型圈不易脱落，密封性能好，延长了使用寿命。
附图说明
图1是本实施例的主视图，为剖视图；
图2是图1中弹簧组3的主视图，为剖视图；
图1、2中：1. 阀盖；2.阀体；3.弹簧组；4.阀瓣；5.Ω形环形槽；6.包覆 O型圈；7. BSP螺纹；8.外弹簧；9.内弹簧。
具体实施方式
如图1、2所示，罐式集装箱外置式安全泄压阀包括阀体2，阀体2上方固定连接阀盖1，阀体2下端口设置有BSP螺纹7，阀体2内腔设置有阀瓣4，阀瓣4与阀盖1之间设置有弹簧，弹簧为弹簧组3，弹簧组3由内弹簧9和外弹簧8叠加组成，阀瓣4下端面开有Ω形环形槽5，Ω形环形槽5内嵌有包覆O型圈6，包覆O型圈6由FEP聚合物包覆的橡胶弹性体组成。
工作时，当罐式集装箱外置式安全泄压阀通过BSP螺纹7与罐体固定连接，当罐体压力大于设定压力时，阀瓣4起跳，实现泄压，当罐体压力小于设定压力时，阀瓣4在弹簧组3的作用下，自动回座。
