Abstract

本实用新型是一种用于蒸汽锅炉或其它储容器 上作为观察液面位置所使用的安全水位计。其主要 技术特征是在现有水位计上下两旋塞阀的进水口内 均分别设有由弹簧、活塞和丝堵组成的自动封闭装 置,丝堵和活塞的凸圆上均带有进水孔。当水位计的 玻璃管或其它部位遭到意外破裂时,推动活塞使活塞 前部与阀体内密封面密合,从而使阀体自动封闭,避 免水汽喷射伤人,以及容器内的贵重原料遭到损失。

Description

本实用新型是一种用于蒸汽锅炉或其它储容器上作为观察液面位置所使用的安全水位计。
现有与本实用新型相关的水位计主要由两个连通锅炉或储容器的上下旋塞阀和一个位于两阀中间且连通两阀的高压玻璃管组成,当该水位计中玻璃管或其它部位遭意外破裂损坏时,由于没有自动封闭装置,这样从破裂处喷射出的水蒸汽极易伤人,因而很不安全,同时也可使存放在容器中的化工、军工原料外泄,造成浪费。
针对上述现有技术存在的不足,本实用新型的目的是提供一种改进了的安全水位计,它能在玻璃管破裂时自动将阀体封闭,避免伤人事故发生和造成原料的浪费。
本实用新型的目的是通过如下技术措施来实现的:在现有水位计的上、下两个旋塞阀体的进水口内均分别增设有弹簧和与该弹簧相连且带有凸圆的活塞以及阻止活塞从进水口脱落的丝堵,该丝堵和活塞的凸圆上均带有进水孔,丝堵和活塞所带凸圆之间设有间隙。正常使用时,水位计与锅炉或其它容器(罐)相通,压力是均衡的,由弹簧将活塞推开,液体通过丝堵和活塞凸圆上的进水孔进入玻璃管内,以观察液面的位置(高度),当玻璃管或其它部位遭到意外破裂或损坏时,旋塞阀外部即没有压力,这时锅炉或其它容器内部的压力作用到活塞上,使活塞前部与阀体密封面密合,从而达到自动封闭作用,以此保证在玻璃管等部位意外破裂或损坏时能避免水汽喷射伤人,以及储存在容器内的贵重原料遭到损失。
本实用新型的具体细节由以下实施例及其附图给出:
图1是本实用新型结构示意图。
图2-3是活塞结构示意图。
图4-5是丝堵结构示意图。
参考附图:本实用新型包括上、下两个旋塞阀1、3和连通上下两个旋塞阀的高压玻璃管2,在两个旋塞阀体的进水口分别设有一弹簧4和与该弹簧相连且带有凸圆6的活塞5及阻止活塞脱落的丝堵7(图1中仅在阀体中给出),活塞5所带凸圆6和丝堵7上均分别带有进水孔10和8,活塞5尾部和丝堵7中间的凸台9相接触,使活塞5尾部与丝堵7之间留有间隙,为保证活塞5在阀体进水口内平行滑动和活塞5所带凸圆6受力均匀,在活塞5上可带有两个凸圆6且每个凸圆上的进水孔10和丝堵7上进水孔8均匀分布,丝堵7上进水孔8略大于凸圆6上的进水孔10,丝堵7上均匀分布的进水孔8的总截面积与阀体内的通水孔截面积相等。

Claims (2)

1、一种蒸汽锅炉或其它储容器上作为观察液面位置所使用的安全水位计,它包括上、下两个旋塞阀和连通两个旋塞阀的玻璃管,其特征是:在上、下两个旋塞阀体的进水口内均匀分别设有弹簧和与该弹簧相连且带有凸圆的活塞以及阻止活塞从进水口脱落的丝堵,该丝堵和活塞所带凸圆之间设有间隙,且丝堵与活塞的凸圆上均带有进水孔。
2、根据权利要求1所述的安全水位计,其特征是:活塞所带凸圆上的进水孔和丝堵上的进水孔为均匀分布。
