Abstract

本实用新型涉及一种单体堵头,锥状堵头主体左端部位呈偏形,堵头主体右端端面中心部位开有螺纹盲孔。本实用新型结构简单、设计合理,易加工、拆卸方便,可重复使用,成本低廉。

Description

单体堵头
技术领域
本实用新型涉及一种单体堵头,尤其是涉及一种火力发电厂、热电厂、石油化工等行业的列管式换热器泄漏后采用的单体堵头。
背景技术
目前,火力发电厂、热电厂、石油化工等行业的列管式换热器换热管泄漏后均采用普通铜堵将其暂时堵住,以便设备正常运行,待泄漏管的数量达到一定比例时,拔出铜堵,拆换新管。而且为能够取出,铜堵要加长尺寸,造成很大的经济浪费,即使加长,其取出过程也很困难,需要用手锤在普通铜堵大端圆周向的不同方向反复敲击方能取下。
发明内容
本实用新型的目的在于克服上述技术中存在的不足之处,提供一种结构简单、设计合理,成本低廉、拆卸方便的单体堵头。
为了达到上述目的,本实用新型采用的技术方案是:锥状堵头主体左端部位呈偏形,堵头主体右端端面中心部位开有螺纹盲孔。
本实用新型的优点是:
结构简单、设计合理,易加工、拆卸方便,可重复使用,成本低廉。
附图说明
图1是本实用新型结构示意图;
具体实施方式
下面结合附图对本实用新型的实施例作进一步详细描述。
由图1可知,本实用新型锥状堵头主体1左端部位呈偏形,堵头主体1右端端面中心部位开有螺纹盲孔2。
本实用新型首先将堵头主体1小端嵌入换热管内孔中,用锤子敲击堵头主体1大端,使换热管壁胀紧,右端加工螺纹盲孔2,用来与拔堵器连接将其从换热管中拔出。用专用拔堵器将换热管拔出。节省材料并可重复使用,从而降低了使用成本。
