Abstract

本实用新型涉及一种用于供水管路上的的新型双蝶式岔阀，岔阀阀体有一个进口及两个方向的出口组成，两个出口对称布置，岔阀由内有两片蝶片，通过旋转蝶片，可使其中一个出口处于联通状态而另外一个出口出于关闭状态，从而实现水流方向的切换。本实用新型由于采用上述结构，可以通过旋转蝶片来改变水流方向，用这种新型岔阀，可以取代供水系统中的岔管及多个阀门的作用，而且流态更为平顺，达到减少水力损失保护管道的作用。

Description

一种双蝶式岔阀
技术领域
本实用新型涉及一种新型双蝶式岔阀。 
背景技术
供水系统及管线上，拥有大量的岔管及岔管配套的阀门，通过阀门的切换，可实现水泵的切换及管路的切换，从而保障供水系统的安全灵活运行。切换流向通常需要一个岔管及多个阀门，占地大，操作复杂，且岔管处流态较差，大大增加了管路损失及水泵电能消耗。 
实用新型内容
本实用新型提供一种新型双蝶片式岔阀，通过旋转蝶片来启闭出口，达到切换流向的作用。 
本实用新型提供的技术方案是：在岔体内安装两个蝶片，可以在关闭一个出口的同时联通另外一个出口，从而实现进口到出口的平顺连接，减小水力损失。 
岔阀体拥有一个进口两个出口，两个出口对称布置，与进口夹角相同，两个出口间夹角α为60至180度。进口出口可以互换。 
上述蝶片为流线型设计，两片对称分布于岔阀体内部，大蝶片与出口直径相同，通过传动装置旋转，旋转到任一出口时可封闭出口；小蝶片呈流线形，与大蝶片相对，起平顺流道减少损失作用；通过旋转蝶片，可实现任意一出口联通，而另外一出口关闭的作用。 
本实用新型由于采用上述结构，可以简化替代岔管及相关阀门布置，使得管路系统中水力损失减小达到保护管路节约电能作用。 
附图说明
图1为双蝶式岔阀示意图。 
图中：①——岔阀体，②——大蝶片，③——小蝶片。 
具体实施方式
参见图1，本实用新型将大蝶片②及小蝶片③对称布置，A为进口，B、C为出口，两个蝶片安装于岔阀体①内。 

Claims (4)

1.一种双蝶式岔阀，其特征是：岔阀体拥有一个进口两个出口，拥有两个蝶片。
2.根据权利要求1所述的双蝶式岔阀，其特征是：两个出口对称布置，与进口夹角相同，两个出口间夹角α为60至180度。
3.根据权利要求1所述的双蝶式岔阀，其特征是：岔阀体内共有两个蝶片，一大一小；大蝶片与出口等径，旋转到出口时可关闭出口；小蝶片呈流线形，与大蝶片相对，起平顺流道减少损失作用；通过旋转蝶片，可实现任意一出口联通，而另外一出口关闭的作用。
4.根据权利要求1所述的双蝶式岔阀，其特征是：进口出口可以互换，也可以是两个进口一个出口。
