Description

二次密封球阀
技术领域
本发明涉及一种球阀，具体地说是一种二次密封球阀。
背景技术
现有球阀，通常采用的是单次密封的结构，这种结构在频繁的使用过程中，当出现密封失灵时，球阀就整体失效。
发明内容
本发明目的是研制出一种二次密封球阀。
本发明要解决的是现有单次密封结构的球阀在出现密封失灵时，球阀整体失效的问题。
本发明的技术方案包括：阀体、球体、阀杆和连接体，设于球体第一端的控油装置和第一阀座，第一阀座与球体的接合处设有第一环形密封圈，球体的第二端设有第二阀座，第二阀座上设有储油室、第二阀座油道，储油室与第二阀座油道相通，第二阀座与球体第二端的接合处设有第二环形密封圈。
本发明具有二次密封的优点，当第一道密封失灵时，还有第二道密封保证。
附图说明
图1是本发明的结构示意图。
图2是本发明储油室周边部分放大后的结构示意图。
具体实施方式
下面实施例及附图对本发明作进一步说明。
如图所示，本发明包括阀体2、球体6、阀杆11和连接体3，设于球体6第一端的控油装置和第一阀座7，第一阀座7与球体6的接合处设有第一环形密封圈12。球体6的第二端设有第二阀座5，第二阀座5与阀体2的接合处设有储油室4、第二阀座油道14，储油室4与第二阀座油道14相通。第二阀座5与球体6第二端的接合处设有第二环形密封圈13。控油装置包括顶杆10、单向阀9、设于第一阀座7上的第一阀座油道8、顶杆10的一端顶与阀杆11上，顶杆10通过单向阀9控制第一阀座油道8的导通。阀体2内设有内腔1，内腔1与储油室4相通。
