Description

电动金属硬密封蝶阀 
[技术领域]
本实用新型涉及阀门技术领域，具体地说电动金属硬密封蝶阀。 
[背景技术]
以前生产的蝶阀仅用“O”型密封圈作衬垫，装配完以后经压力测试合格后出厂，用户使用一段时间后出现跑、渗、漏的缺陷，这严重影响了产品的质量。 
[发明内容]
电动金属硬密封蝶阀，其特征在于，包括电动手轮1、控制箱2、衬套3、“O”型密封圈4、环形凹槽5、阀座6、主轴7、阀体8，控制箱2设于阀座6上，电动手轮1与控制箱2连接，所述的衬套3安装在穿过阀座6和阀体8的主轴7上，并位于阀体8与阀座6的结合部，环形凹槽5设于衬套3上，“O”型密封圈4镶嵌在衬套3的径向上。所述的蝶阀的衬套3由聚四氟乙烯材料制成，所述的蝶阀，环形凹槽5外侧面夹角可为80-100°，环形凹槽5数量为1-2个。 
本实用新型的优点是：由于生产的蝶阀的具有衬套，在衬套的径向嵌设有“O”型密封圈，衬套3的轴向上设有1-2个环形凹槽5，而且蝶阀关键部位足经过专门设计的，使密封性能大大增强，有效的克服了蝶阀存在的跑、渗、漏的缺陷，使用效果明显。 
[附图说明]
图1为本实用新型的结构局部剖视图。 
图2为本实用新型的环形凹槽结构位置局部剖视图。 
图中：为电动手轮，2为控制箱，3为衬套，4为“O”型密封圈，5为环形凹槽，6为阀座，7为主轴，8为阀体。 
[具体实施方式]
下面结合附图和具体实施方式对本实用新型作详细描述： 
聚四氟乙烯材料具有良好的伸缩性、耐摩擦、润滑性能好的特点，用聚四氟乙烯材料作衬胶阀门的衬套，聚四氟乙烯材料经造型、加工、烧结然后按照刁<同规格尺寸切削加工成型，再将“O”型密封圈嵌在衬套的径向，再将衬套安装在穿过阀门的阀体、阀座的主轴上，并位于阀体与阀座的结合部，即蝶阀的关键部位。阀门的衬套上还设有1-2个对应的环形凹槽内。由于整个蝶阀是上下对夹紧固的，当蝶板开启或关闭时衬套上的“O”型密封圈和衬套上的会起到有效的密封作用，从而克服了蝶阀存在的跑、渗、漏的缺陷，保证了蝶阀的质量。
