Abstract

本实用新型公开了一种止回阀,它包括闸阀[1]和止回阀[2],所述闸阀[1]的出口与止回阀[2]的入口固连为一起,使介质从闸阀[1]流出直接进入止回阀[2]。本实用新型节约了材料,降低了成本;安装时无需安装接头及相互之间的连接,因此节约了时间,提高了效率。

Description

一种止回阀
技术领域
本实用新型涉及一种阀门,确切地说是一种闸阀与止回阀共同组合的阀门。
背景技术
止回阀和闸阀广泛应用于生产生活的各个领域。现有的石油、化工、制药、电力行业、高层建筑等各种工况的管路既需要做到对介质实现开闭,又要对介质止回,因此管路上需要同时安装闸阀和止回阀。而闸阀和止回阀是两个独立的产品,因此止回阀和闸阀之间的连接还需在二者之间安装管件接头才能实现。上述安装方式的缺点是:止回阀和闸阀所用原材料不能节省,加工费工耗时,浪费资源,因此使用成本高。
实用新型内容
本实用新型的目的就是解决现有的管路上既安装闸阀又安装止回阀,原材料不能节省,加工费工耗时,浪费资源,使用成本高的问题。
本实用新型采用的技术方案是:一种止回阀,它包括闸阀和止回阀,其特征是所述闸阀的出口与止回阀的入口固连为一起,使介质从闸阀流出直接进入止回阀。
采用上述技术方案,止回阀和闸阀连为一体,这样在加工时少加工连接端面的两个法兰,安装时也不需用螺栓进行连接,并省去了两者之间的接头。
本实用新型有益效果是:由于加工时加工量得到减小,因此节约了材料,降低了成本;安装时无需安装接头及相互之间的连接,因此节约了时间,提高了效率。
附图说明
图1为本实用新型结构示意图。
具体实施方式
本实用新型一种止回阀,如图1所示,它包括闸阀1和止回阀2,所述闸阀1的出口与止回阀2的入口固连为一起,使介质从闸阀1流出直接进入止回阀2。
