Description

旋转止回阀
技术领域
本实用新型涉及一种旋转止回阀。
背景技术
旋转止回阀的启闭件靠介质流动和力量自行开启或关闭,以防止介质倒流的阀门叫旋转止回阀。旋转止回阀属于自动阀类,主要用于介质单向流动的管道上,只允许介质向一个方向流动,以防止发生事故。球型污水旋转止回阀:阀体采用全通道结构,具有流量大、阻力小之优点。采用圆球做阀瓣,适用于高粘度、有悬浮物的工业及生活污水管网。
实用新型内容
    本实用新型提供一种结构设计合理,止水效果好的可以广泛应用于高层建筑、给排水管道中。
本实用新型解决技术问题提供如下方案:
一种旋转止回阀,包括阀体,其特征在于:所述阀体内具有阀腔,所述阀体的左、右两端分别设有进、出水口,所述阀体的上端设有开口,所述开口上密封安装有阀盖,所述阀盖的下表面左端设有压脚、中部设有挡块,所述进水口一侧的阀腔内壁上具有支架,所述支架上铰接有摇杆,所述摇杆的一端固定安装有阀瓣,所述阀腔左侧进水口的侧壁上安装有阀座,所述阀瓣搭接在阀座上。
所述阀盖与阀体之间安装有密封垫圈。
本实用新型结构设计合理,阀瓣上配有重块,止水效果好,可以广泛应用于高层建筑、给排水管道中。
附图说明
图1为本实用新型的结构示意图。
具体实施方式
参见附图,一种旋转止回阀,包括阀体1,所述阀体1内具有阀腔2,所述阀体1的左、右两端分别设有进、出水口3、4,所述阀体的上端设有开口5,所述开口5上密封安装有阀盖6,所述阀盖6的下表面左端设有压脚11、中部设有挡块13,所述进水口3一侧的阀腔内壁上具有支架7,所述支架7上铰接有摇杆8,所述摇杆8的一端固定安装有阀瓣9,所述阀腔2左侧进水口的侧壁上安装有阀座10,所述阀瓣9搭接在阀座10上,所述阀盖6与阀体1之间安装有密封垫圈12。
