Abstract

本实用新型公开了一种多用途球阀，包括阀座，设置于阀座内的球状阀芯，作为改进，所述的球状阀芯通道内设有锥孔及与锥孔配合堵住球状阀芯通道的活塞，所述的活塞包括与锥孔配合的球面构件，球面构件后侧设有导向杆，导向杆上设有压簧，所述的球状阀芯通道内还设有定位导向杆的支架，所述的设置于导向杆上的压簧位于球面构件与支架之间保持球面构件与锥孔配合的弹性趋势。本实用新型在球状阀芯的通道内设置锥孔及相配合的活塞，构成一止回阀，通过翻转球状阀芯，可达到球阀双向止回的目的，其有益效果是可极大的简化管路结构及管路部件。

Description

一种多用途球阀
技术领域
本实用新型涉及一种多用途球阀。
背景技术
目前的球阀功能单一，仅仅起到关闭或打开水流通道的目的，而位于管路上的止回阀单向止回，需要应用于双向止回的管路，往往通过两个单向止回阀来实现，造成管路结构复杂。
发明内容
本实用新型为解决现有技术在使用中存在球阀功能单一、双向止回管路中结构复杂的问题，提供一中可以双向止回的多用途球阀。
本实用新型解决现有问题的技术方案是：一种多用途球阀，包括阀座，设置于阀座内的球状阀芯，作为改进，所述的球状阀芯通道内设有锥孔及与锥孔配合堵住球状阀芯通道的活塞，所述的活塞包括与锥孔配合的球面构件，球面构件后侧设有导向杆，导向杆上设有压簧，所述的球状阀芯通道内还设有定位导向杆的支架，所述的设置于导向杆上的压簧位于球面构件与支架之间保持球面构件与锥孔配合的弹性趋势。
作为进一步改进，所述的球面构件芯部设有构架，构架上复合有铝层或铜层。
本实用新型与现有技术相比较，通过在球状阀芯的通道内设置锥孔及相配合的活塞，构成一止回阀，通过翻转球状阀芯，可达到球阀双向止回的目的，其有益效果是可极大的简化管路结构及管路部件。
附图说明
图1是本实用新型的结构示意图。
具体实施方式
参见图1，本实施案例包括阀座1，设置于阀座1内的球状阀芯2，球状阀芯2通道内设有锥孔3及与锥孔3配合堵住球状阀芯2通道的活塞4，活塞4包括与锥孔3配合的球面构件41，球面构件41后侧设有导向杆42，导向杆42上设有压簧43，球状阀芯2通道内还设有定位导向杆42的支架44，设置于导向杆42上的压簧43位于球面构件41与支架44之间保持球面构件41与锥孔3配合的弹性趋势。
本实施案例中，球面构件41芯部设有构架5，构架5上复合有铝层或铜层，以防止因球面构件表面磨损导致泄漏，质软的铝层或铜层与锥孔3相咬合匹配。

Claims (2)
