为了克服现有中线衬胶蝶阀在介质压力较高时轴端处易泄漏的不足,本实用新型提供一种中线衬胶蝶阀。
本实用新型解决其技术问题所采用的技术方案是一种中线衬胶蝶阀,包括阀体、阀轴、上轴承、O形圈、下轴承、蝶板、阀座,阀座安装于阀体内,上轴承与下轴承之间装有O形圈,下轴承的下端有一台阶,台阶一端伸入阀座相应的槽内。
本实用新型的有益效果是阀轴与阀体间采用多道密封,密封可靠。
附图说明
下面结合附图和实施例对本实用新型作进一步说明。
图1是本实施例的构造图;
图中:1.阀体;2.上轴承;3.O形圈;4.下轴承;5.阀座;6.台阶;7.蝶板;8.阀轴。
具体实施方式
一种中线衬胶蝶阀,包括阀体1、阀轴8、上轴承2、O形圈3、下轴承4、蝶板7、阀座5,阀座5安装于阀体1内,上轴承2与下轴承4之间装有O形圈3,下轴承4的下端有一台阶6,台阶6一端伸入阀座5相应的槽内。
