The method is characterized in that a guide sleeve (7), a double-layer sealing ring (2) with a framework, felt (1), a front end cover plate (4) and a bottom shell (10) are included, an oil injection hole (6) is formed in the top of the end face of the guide sleeve (7), and the oil injection hole (6) is sealed through a fastener; a sealing piece assembling cavity (5) is machined in the center of the end face of the guide sleeve (7), and felt (1) and a double-layer sealing ring (2) with a framework are sequentially placed on the guide sleeve (7) from outside to inside. The felt (1) is soaked in oil, and the sealing pieces are sequentially stacked into the sealing piece assembly cavity (5), then slightly protrude out of the end face of the guide sleeve (7) and are pressed through the front end cover plate (4) to fill the sealing piece assembly cavity (5) of the guide sleeve (7). The sealing waterproof performance of the square indication rod can be enhanced by improving the working reliability of the close-fitting inspection device, meanwhile, a drainage channel is provided for accumulated water entering the machine, and the drainage characteristic of a round rod machine type is improved.

    本发明涉及一种免维护的密检器密封排水方法,其特征是:包括:导向套(7)、双层带骨架密封圈(2)、毛毡(1)、前端盖板(4)、底壳(10),其中导向套(7)在端面顶部开设有注油孔(6),用紧固件密封;导向套(7)端面中心加工有密封件装配腔(5),导向套(7)由外向内依次放置有毛毡(1)和双层带骨架密封圈(2);所述的毛毡(1)浸润油液,密封件依次叠放入密封件装配腔(5)后略凸出导向套(7)端面,通过前端盖板(4)压紧、填满导向套(7)的密封件装配腔(5);它能提高密贴检查器工作可靠性以增强方形表示杆的密封防水性能,同时对进入机内的积水提供排水通道,提升圆杆机型的排水特性。
