Abstract

因压力锅的阀门被堵而造成压力锅爆炸的安全事故时有发生。本发明针对“压力锅绝爆限压阀”设计上的重大缺陷，采用在压力锅盖排汽管入口处设置排堵环的措施，既消除了因锅内食物被穿刺在阀芯针状体上而造成排汽管入口被堵的隐患，又使阀芯针状体不至于因移动或放置锅盖时被碰弯而造成排汽管密封失效的故障。

Description

压力锅自排堵绝爆阀
一、技术领域
本发明涉及压力锅阀门技术，特别是针对专利号为ZL00222484.4的压力锅绝爆限压阀的重要技术改进。
二、背景技术
因压力锅的阀门被堵而造成压力锅爆炸的安全事故时有发生。由本发明人设计的专利号为ZL00222484.4的压力锅绝爆限压阀，将压力锅的排气管的密封位置由通常的上管口改为下管口，并让汽锤中的阀芯穿越排汽管并自排汽管下端伸出一段针状体，使压力锅排汽管内和排汽管入口处堵塞得到改善，但是原设计忽视了一个重要的使用环节，这就是当在压力锅内炖整鸡、整鸭或炖蹄膀或炖冬瓜、大枣之类的食物时，由于锅内被炖物的剧烈翻腾和内部积气会造成锅内食物上浮，而炖火巴后的食物极易被穿刺在阀芯下端伸出的针状体上。一旦出现这种穿刺现象，被穿刺的食物会牢牢地紧贴排汽管的下端入口，这同样会引发压力锅的爆炸，因此压力锅绝爆限压阀实际上是一个不完整结构。
三、发明内容
本发明的目的是针对压力锅绝爆限压阀的重大设计缺陷，提供一种能完全消除其爆炸隐患的压力锅自排堵绝爆阀。
本发明的目的是这样实现的：在专利号为ZL00222484.4，名称为“压力锅绝爆限压阀”的基础上增设一个与之配套的排堵环，排堵环系由一块长9～10cm、厚0.3～0.5mm的条形不锈钢片构成，其两端为圆环形，圆环的内孔直径为8mm，环宽2～3mm，连接两圆环之间的平行宽度为6～8mm，将此条形不锈钢片弯成圆形，并使其两端圆环重叠后将排汽管自压力锅盖外侧的排汽管安装孔穿入，再穿越重叠的两圆环后用排汽管紧固螺帽将重叠的两圆环紧固在此螺帽与压力锅盖内表面之间，使条形不锈钢片构成排堵环，最后将阀锤中心的阀芯由外向内自排汽管的入口中穿出，穿出后的阀芯下端头距排堵环的间距为2～3mm。
采用上述方案后，可收到如下显著效果：
1、自排汽管入口处穿出的阀芯针状体处于由条形不锈钢片构成的排堵环之中，其结构如同枪管端部的准心，压力锅内的被炖物无论怎样翻腾、上浮，都会因排堵环的阻挡而不会被阀芯针状体穿刺而堵住排汽管入口，从而消除了压力锅绝爆限压阀的重大安全隐患，从而使压力锅的主阀——限压阀能真正达到绝爆的效果。
2、原压力锅绝爆限压阀的阀芯针状体处于无保护状态，极易因压力锅盖的移动或放置而被碰弯，将失去排汽管入口的密封作用，而用户难以自行准确矫正，从而使压力锅顿时失去压力作用。而采用本方案后，由于排堵环的保护，上述问题即不复存在。
