【技术实现步骤摘要】
本技术涉及控制水位进水的保护装置,主要适用于饮水机行业和饮料行业等,即作为饮水机自动进水部件,也可用于其它设备控制液位,例如蓄水柜水位的自控进液保护装置。
技术介绍
饮水机已成为人们的主要饮水设备,被广泛地应用于家庭、机关和企事业单位,不仅数量在迅速地增加,而且质量、档次也在不断提高,型式、品种逐渐追求新颖完美。已有饮水机(包括饮料机)通常在其顶端配置一只储水桶,作为正常饮用水水源使用,所以存在着如下缺陷一是外型不美观,并且调换时十分费劲,很不方便;二是储水桶内的水使用时间过久,水质变坏,不可饮用。因此目前设计了经处理过的自来水送到饮水机内储水罐中(不使用储水桶),送到饮水机储水罐的自来水需要液位控制,避免进水过量。现有技术在储水罐内的上部安装单浮球水位控制装置或单浮球加电控阀门水位控制装置,该类控制装置存在的共同缺陷是单浮球一旦出现故障,或者电控出事故都不能起到有效的保护作用。
技术实现思路
本技术为了克服已有储水罐中液位控制的缺陷,提供一种自控进液双重保护装置。该自控进液双重保护装置的技术方案是有一个储水罐,储水罐上连接罐盖,罐内安装水浮力控制阀,其特征在于所述 ...
