Description

具有双金属片泄压阀的锅盖
技术领域
本实用新型涉及一种锅盖，特别是一种可以防止锅内汤汁溢出的具有双金属片泄压阀的锅盖。
背景技术
人们在进行蒸、煮等烹饪活动时，与锅体相配的锅盖往往会在锅内蒸汽的作用下顶起，锅内沸腾状态的汤汁便会从锅盖与锅体之间的缝隙中溢出，不仅污染环境，而且还有可能烫伤烹饪人员，最严重的后果是，溢出的汤汁将火扑灭，造成煤气泄漏，给使用者的生命安全带来极大的安全隐患。为了解决这个问题，操作者只能等待锅内的汤汁沸腾后，将锅盖移开一定角度，让锅内的蒸汽从缝隙中散发出来，这样就给操作者带来了额外的劳动，而且等待汤汁沸腾还需要一定的时间，效率较低。因此现在需要一种能够解决上述问题的新型锅盖。
发明内容
本实用新型是为了解决现有技术所存在的上述不足，提出一种结构简单，设计巧妙，布局合理，能够自动将锅体内腔与外界相连通，防止锅内汤汁溢出具有双金属片泄压阀的锅盖。
本实用新型的技术解决方案是：一种具有双金属片泄压阀的锅盖，包括锅盖体1，在锅盖体1上固定连接有把手2，其特征在于：所述的把手2固定设置在开设于锅盖体1上的开口3内，在把手2的下部设置有与开口3相通的下开口4，同样设置在把手2内的上开口5与下开口4相通，上开口5与把手2内的腔室6连通，在锅盖体1上方的把手2上还设置有与腔室6相通的蒸汽出口8，在上开口5上方的腔室6内设置有固定柱9，固定柱9上设置有双金属片7，双金属片7的横断面为弧形，且双金属片7的外边缘能够将上开口5完全封闭。
所述的双金属片7与上开口5相接触的部分设置有密封圈10。
本实用新型同现有技术相比，具有如下优点：
本种结构形式的具有双金属片泄压阀的锅盖，其结构简单，设计巧妙，布局合理，它针对现有的锅盖无法自动排出蒸汽的缺点，设计出可以在锅内汤汁沸腾、产生蒸汽后自动开启的泄压阀，它巧妙的利用了组成双金属片的不同种类金属之间存在热膨胀系数差，在受热时会向一侧发生弯曲的特性，来实现锅内与外界的自动连通或关闭，不需要操作者看守，减轻了操作者的劳动量，节省了时间，并且当停止加热后，随着温度的降低，双金属片又会恢复到初始状态，将锅体内部与外界重新分隔开来，起到保温的作用。因此可以说这种锅盖具备了多种优点，特别适合于在本领域中推广应用，其市场前景十分广阔。
附图说明
图1是本实用新型实施例的结构示意图。
具体实施方式
下面将结合附图说明本实用新型的具体实施方式。如图1所示：一种具有双金属片泄压阀的锅盖，包括锅盖体1，在锅盖体1上设置有开口3，把手2固定在开口3内，把手2的下部设置有与开口3相连通的下开口4，这个下开口4与上开口5共同组成供气体流动的蒸汽通道，在上开口5上方的腔室6内设置有固定柱9，在固定柱9上设置有双金属片7，这个双金属片7的断面为弧形，在双金属片7与上开口5相接触的部分还设置有密封圈10，这个密封圈10可以设置在双金属片7的边缘，也可以设置在上开口5处；并且双金属片7的外边缘能够将上开口5完全封闭，也就是说双金属片7可以与密封圈10共同将上开口5密封起来；在锅盖体1上方的把手2上还设置有与腔室6相通的蒸汽出口8。
本种结构形式的具有双金属片泄压阀的锅盖的工作过程如下：配有本种锅盖的锅在进行蒸、煮等烹饪活动时，当国内的汤汁等液体被加热至沸腾后，会产生大量的蒸汽，这些蒸汽通过下开口4、上开口5后，与双金属片7发生接触，在初始状态下，双金属片7的形状为向下突起，其边缘与下开口5相接触，并与密封圈10共同形成密封状态，当温度较高的蒸汽与双金属片7发生接触后，由于组成双金属片7的两种不同金属之间的热膨胀系数不同，双金属片7向上弯曲，其边缘与上开口5脱离接触，即将上开口5开启，这样水蒸汽便会通过上开口5、腔室6和蒸汽出口8排出到外界，实现泄压阀的自动开启；
当烹饪工作完成，停止加热后，双金属片7周围的温度逐渐降低，并且随着温度的降低，双金属片7向下弯曲，其边缘与下开口5重新接触，并与密封圈10共同将锅体内部重新密封起来。
