Description

救生舱用泄压阀的制造方法
所属技术领域：
本发明涉及一种阀门制造方法，特别涉及一种救生舱用泄压阀的制造方法，矿井下救生舱设备在运行工作时，控制舱体内部压力的单向气体阀门。
背景技术：
现在救生舱用的泄压阀都是用弹簧来调整舱体内压力的，由于煤矿井下环境气体复杂，含有许多腐蚀性的气体，所以弹簧在井下环境中，弹簧系数很快就会改变的，且弹簧结构不能调节设定压力值，这样就直接影响了救生舱内的密封压力值，就直接危险到避险人员的生命安全。
发明内容：
针对现有上述产品的技术不足，本发明的目的就是提供一种救生舱用泄压阀的制造方法。
本发明解决其技术问题所采用的技术方案是：磁体和阀盖外表都采用耐腐蚀的硅橡胶体胶封，上磁体与上阀盖之间采用极性相同的磁极，下磁体与下阀盖之间采用极性相反的磁极，上磁体为螺母型内螺纹，下磁体加工成外螺纹结构；将下磁体安装在下阀体底面中心的螺纹孔中，调节好与下阀盖之间的距离，再将上磁体装在中阀体的沉孔中，适当调节与上阀盖之间的距离；上阀盖与下阀盖连接在中阀体的上下端，上、下阀体与中阀体之间均设有凹部，上、下阀盖分别安装这二凹部里，阀盖边缘圈高于阀盖面，阀盖边缘圈与阀盖是一体，再组合成整个阀体，缝隙焊后磨平，整个阀体为圆柱形状。
本发明有益效果：保证避险人员的生命安全，实现舱内压力的自动调节与平衡。
附图说明：
图1为本发明的结构示意图；
图中，1、上阀体2、上阀盖3、阀盖边缘圈4、上磁铁5、硅橡胶体6、中阀体7、下磁铁8、下阀体。
具体实施方式：
如附图1所示，本发明目的就是提供一种救生舱用泄压阀，由二个磁体、二个阀盖、一个阀体组成阀，缝隙焊后磨平，整个阀体为圆柱形状，安装在导通舱体外部的管路上，能自动作开启的单向阀。上磁体4制成内螺纹的螺母，安装在中阀体6的圆形沉孔中，整个圆形沉孔的垂直截面是“山”字形状，上磁体4套在“山”字的中间柱上，在“山”字的中间柱上调节与上阀盖2的间距，上磁体4外表有硅橡胶体5胶封，上磁体4与上阀盖2之间采用极性相同的磁极，形成相反的作用力，磁力克服阀盖重力的作用，常态时上阀盖处于向下临界闭合状态，上阀盖2连接“山”字的中间柱顶，上阀体1与中阀体6之间设有凹部，上阀盖2安装在凹部里，阀盖边缘圈3高于阀盖面，阀盖边缘圈3与阀盖是一体；下阀体8的底面中间设有螺纹孔，下磁体7安装在螺纹孔中，下磁体7加工成外螺纹结构，可以控制调节与下阀盖之间的距离，进而控制本阀泄压开启的压力值，下磁体7与下阀盖8之间采用极性相反的磁极，形成相互吸引的作用，常态下下阀盖处于闭合状态，下磁体7外表有硅橡胶体5胶封，下部阀体8与中阀体6之间设有凹部，下阀盖安装凹部在下磁体7的上面，下阀盖安装凹部里；磁体外表设硅橡胶体5胶封，能很好保护磁体免受外界气体环境影响磁体本身磁性，保证了阀的可靠性。
