Description

一种蝶式双瓣止回阀的密封结构
技术领域
本实用新型涉及一种密封结构,尤其是一种蝶式双瓣止回阀的密封结构。
背景技术
目前在各行业使用的蝶式双瓣止回阀,其密封圈直接硫化在阀体,密封圈与阀体之间为平面接触,其存在如下不足:1、密封圈在使用过程中有脱落的隐患,2、更换密封圈必须至制造厂重新硫化。
发明内容
为了克服现有蝶式双瓣止回阀密封圈在使用过程中有脱落的隐患,更换密封圈非常不便的不足,本实用新型提供一种蝶式双瓣止回阀的密封结构。
本实用新型解决其技术问题所采用的技术方案是一种蝶式双瓣止回阀的密封结构,包括阀体、密封圈,阀体上与密封圈配合部位开有沟槽,沟槽的底部尺寸大于沟槽的口部尺寸,密封圈镶嵌在沟槽内。
本实用新型的有益效果是密封圈与阀体靠机械方式连接,长期使用无脱落风险,用户在现场即可方便地更换密封圈。
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.沟槽;3.密封圈。
具体实施方式
一种蝶式双瓣止回阀的密封结构,包括阀体1、密封圈3,阀体1上与密封圈3配合部位开有沟槽2,沟槽2的底部尺寸大于沟槽2的口部尺寸,密封圈3镶嵌在沟槽2内,可在现场方便地更换密封圈3。
