Abstract

压力锅排气防堵装置,设有下盖[1],卡座[2],螺 母[3],阀芯[4]组成,卡座和下盖都设有斜形凸卡互相 配合,下盖开设有许多排气孔[7],有效避免了物体堵 塞阀芯排气孔,防止压力锅内压力升高引起爆炸事 故,确保压力锅使用的绝对安全性。

Description

本实用新型涉及一种家用压力锅排气装置,特别是一种压力锅排气防堵装置。
目前,压力锅已进入千家万户,在压力锅盖上设有排气阀和保险阀,对锅内气压限制在安全范围内,压力高时,气体由排气阀排出,当出现意外超压时,保险阀起作用,排泄减压,但由于排气阀和保险阀的排气孔都设计较小,容易被锅内物体堵塞,使锅内压力升高引起爆炸,据中国商报介绍,我国每年至少有6000只高压锅爆炸,其直接原因是锅盖上所有排气孔被堵塞所致,危害人身安全。
本实用新型的目的是为克服上述现有技术的缺点而提供一种改进的压力锅排气防堵装置,保证压力锅正党排气限压,确保使用安全性。
本实用新型的目的可以通过以下措施来实现:本排气装置设有阀芯,螺母、卡座和下盖,卡座由螺母固定在阀芯上,卡座的外侧设有斜形凸卡,下盖内侧设有斜形凸卡与卡座外侧的斜形凸卡配合,下盖的盖体上开设有多个气孔。应用时,压力锅内气体可经下盖的气孔和阀芯排气孔排出,由于下盖有许多气孔,所以被全部堵塞的机会几乎为零,下盖可旋拆下来清洗,保持干净卫生。
本实用新型的具体结构和实施例由以下附图给出:
图1是压力锅排气防堵装置的纵向剖面图;
图2是本实用新型卡座的主视图;
图3是本实用新型下盖的俯视图。
以下将结合附图对本实用新型作进一步详述:参照图1,本装置的阀芯[4]由螺母[3]固定在锅盖[6]上,阀芯的中心是排气孔[5],卡座[2]由螺母[3]固定,卡座的外侧设有斜形凸卡[8],见图2,下盖[1]装在卡座[2]下,下盖内侧的斜形凸卡[9]与卡座斜形凸卡[8]配合,下盖的侧向和下面都开设有气孔[7],见图3,气孔[7]的直径最好为2-2.5毫米,(因排气孔[5]的直径为3毫米)锅内的气体由下盖[1]的气孔[7]向阀芯排气孔[5]排出,保持锅内压力在正常范围。下盖为易拆件,方便拆下清洗。
本实用新型的结构简单,设计合理,有效地防止物体堵塞排气孔造成压力升高,制造实施容易,使用方便,成本低廉,特别是与本人发明的专利93219791.4“压力锅超压自动双排气撞针防堵保险阀”结合使用,可百分之百确保压力锅的安全使用,保障人身安全。
