Abstract

一种压力锅限压阀包括:由金属材料制成的阀体和阀体芯;阀体芯下部设有限压阀阀杆;所述的阀体外设有阀体罩,阀体罩注压于阀体的上表面和侧面,并设有与阀体出气孔相应的开孔,阀体罩由热导率小的非金属材料制成。由于阀体外设有阀体罩,阀体罩由热导率小的非金属材料制成,使得限压阀具有防烫手功能。由于阀体罩直接注压于阀体表面,使得阀体罩牢固、不易损坏。

Description

压力锅限压阀
本实用新型涉及压力锅技术领域,特别涉及一种压力锅限压阀。
目前,重锤式压力锅限压阀的阀体多采用金属制作,在摘取(或提升)限压阀时极易烫伤手。中国专利96202701.4号公开了一种压力锁限压阀,其阀体外侧设有阀盖,阀盖与阀柄联接,阀盖和阀体之间留有空隙。其可将锅内喷出的蒸气挡在阀盖内侧,不会烫伤使用者。但此种限压阀的阀柄与阀盖,通过阀柄底部的凹槽和阀盖内侧的凸出榫相连,阀盖与阀体间无连接点使得阀盖很容易损坏。再者,此种限压阀的制造较复杂,制造成本高。难以适应使用者的要求。
本实用新型的目的在于:提供一种具有防烫手功能、制造方便的压力锅限压阀。
为了达到以上所述的目的,本实用新型是通过以下技术方案来实现的:
一种压力锅限压阀包括:由金属材料制成的阀体和阀体芯;阀体芯下部设有限压阀阀杆;所述的阀体外设有阀体罩,阀体罩注压于阀体的上表面和侧面,并与阀体结合成一体;阀体罩设有与阀体出气孔相应的开孔,阀体罩由热导率小的非金属材料制成。
在本实用新型中,所述的热导率小的非金属材料是尼龙或塑料,当然也可以是其它热导率小的材料。
本实用新型的优点在于:由于阀体外设有阀体罩,阀体罩由热导率小的非金属材料制成,使得限压阀具有防烫手功能。由于阀体罩直接注压于阀体表面,使得阀体罩牢固、不易损坏,且制造方便。
为了更加清楚的说明本实用新型,下面结合附图进行详细说明:
图1是本实用新型实施例1结构示意图。
图2是本实用新型实施例2结构示意图。
如图1所示:限压阀包括:由金属材料制成的阀体1和阀体芯2;阀体芯2下部设有限压阀阀杆3;限压阀阀杆固定于压力锅锅盖7上,阀体下部内壁上设有卡簧8;阀体外设有阀体罩4,尼龙阀体罩4注压于阀体1的上表面和侧面,并设有与阀体出气孔5相应的开孔6。使得限压阀具有防烫手功能,且制造方便。
图2给出了本实用新型的另一实施例。在本实施例中,阀体罩由塑料材料注压于阀体表面而成,其它与实施例1相同。
在本实用新型中,限压阀可以是固定式的,当然也可以是可拆卸式的。

Claims (2)

1、一种压力锅限压阀包括:由金属材料制成的阀体和阀体芯;阀体芯下部设有限压阀阀杆;其特征在于:所述的阀体外设有阀体罩,阀体罩注压于阀体的上表面和侧面,并与阀体结合成一体;阀体罩设有与阀体出气孔相应的开孔,阀体罩由热导率小的非金属材料制成。
2、根据权利要求1所述的压力锅限压阀,其特征在于:所述的热导率小的非金属材料是尼龙或塑料。
