Description

一种自动增压密封蜗壳门
技术领域
 本实用新型涉及水轮蜗壳密封装置技术领域，具体涉及一种自动增压密封蜗壳门。
背景技术
水轮发电机组的蜗壳进人门是供检修人员进出用的，现行的检修进人门是门盖往外开的，检修完后再将门盖上，并用螺栓压紧密封，当蜗壳水压较大时会出现渗水现象。
发明内容
本实用新型的目的是提供一种自动增压密封蜗壳门，它结构简单，采用内开式密封门结构，借助蜗壳内部的水压压紧密封门，使得密封效果更好。
为了解决背景技术所存在的问题，本实用新型是采用以下技术方案：它包含蜗壳1、密封门2、手柄3、门铰链连接件4、密封垫5、旋转自锁装置6，密封门2的右侧通过门铰链连接件4与蜗壳1连接，密封门2的两侧设置有密封垫5，密封垫5的外侧中间设置有手柄3，密封门2的右侧设置有旋转自锁装置6。
本实用新型具有以下有益效果：它结构简单，采用内开式密封门结构，借助蜗壳内部的水压压紧密封门，使得密封效果更好。
附图说明：
图1是本实用新型结构示意图。
具体实施方式：
参看图1，本具体实施方式采用以下技术方案：它包含蜗壳1、密封门2、手柄3、门铰链连接件4、密封垫5、旋转自锁装置6，密封门2的右侧通过门铰链连接件4与蜗壳1连接，密封门2的两侧设置有密封垫5，密封垫5的外侧中间设置有手柄3，密封门2的右侧设置有旋转自锁装置6。
所述的密封门2为向内开启结构，可以借助蜗壳水压来压紧门边的密封垫，起到更好的密封效果。
本具体实施方式具有以下有益效果：它结构简单，采用内开式密封门结构，借助蜗壳内部的水压压紧密封门，使得密封效果更好。
