Abstract

一种旋启式三通止回阀。能够应用于三通管道并保证其中两个管道防止介质倒流，它是在类似三通管道的阀体中的横向左侧管道和轴向管道增加密封面，采用金属板附四氟橡胶为阀瓣，阀瓣被转轴固定在阀体上，并只能沿横向管道中心线方向做转动。当横向左侧管道和轴向管道中的一个流入介质时，阀瓣与另一个管道的密封面密封，介质从横向右侧管道流出，并且防止了横向左侧和轴向管道的介质倒流。此阀门具有消声式关闭，水锤压力小，密封性能良好，可用于冷水、热水、工业及生活用水管网系统中。

Description

旋启式三通止回阀
技术领域
 本发明属于一种旋启式三通止回阀，能普遍应用在暖通及给排水行业上。
背景技术
阀门，尤其是止回阀是管路中不可或缺的部件，在水利系统中，止回阀防止水倒流的作用无可替代。同时，由于管路水利的特性，需要两个管道进入同一个管道中，而这两个管道不能连通，这就需要一种三通，并且水锤力小的止回阀。
发明内容
本发明内容是：结合瓣式止回阀和三通管的结构原理加以改进，发明出一种能够应用于三通管道并保证其中两个管道防止介质倒流的阀门。
本发明解决其技术问题所采用的技术方案是：在类似三通管道的阀体中的横向左侧管道和轴向管道增加密封面，采用金属板附四氟橡胶为阀瓣，当横向左侧管道和轴向管道中的一个流入介质时，阀瓣与另一个管道的密封面密封，介质从横向右侧管道流出，并且防止了横向左侧和轴向管道的介质倒流。
本发明的有益效果是：三通，止回，水锤力小。带来的效益是简化管路，极大的节约了能源；止回，保证管路介质的清洁安全；微小水锤力，保证管网运行安全。
附图说明
图1是介质从阀门轴向管道进入，从横向右侧管道流出。
图2是介质从阀门横向左侧管道进入，从横向右侧管道流出。
图中：1、阀体，2、阀瓣，3、转轴。
具体实施方式
下面结合附图和实施例对本发明进一步说明。
在图1中，在阀体（1）内腔中，轴向管道和横向左侧管道口有密封平台，阀瓣（2）安装后与此形成密封；阀瓣（2）为金属板附四氟橡胶，把阀瓣（2）从横向右侧管道放入阀体（1），再放入转轴（3）并固定。当介质从轴向管道进入时，阀瓣（2）在介质的作用下快速与横向左侧的阀座面贴合，保证密封，使流体介质从横向右侧管道流出。
在图2中，当介质从横向左侧管道进入时，阀瓣（2）在介质的作用下快速与轴向的阀座面贴合，保证密封，使流体介质从横向右侧管道流出。
本发明实现了轴向管道和横向左侧管道的介质都能进入横向右侧管道，而阻止轴向管道和横向左侧管道的介质倒流。
