Detailed description of the invention
As shown in the figure, this utility model includes circulating sleeve main body, it is provided with opening in the middle part of circulating sleeve main body, the circulating sleeve main body of open front side is provided with key, it is provided with restrictor ring inside open back side circulating sleeve main body and Open attachment end, open back side circulating sleeve main body is circumferentially provided with first annular groove away from opening outer wall along circulating sleeve, is provided with the first sealing ring in first annular groove。
The internal diameter of described circulating sleeve main body is 60mm, long 583mm。
Described circulating sleeve main body adopts SUS304 rustless steel main body；Described first annular groove is multiple, arranges along circulating sleeve principal length direction。SUS304 rustless steel main body is corrosion-resistant, high temperature resistant, acidproof, alkaline-resisting。Multi-layer sealed, prevent drilling fluid from oozing out from circulating sleeve tail end further；Improve safety, reliability further。
Inside described circulating sleeve main body, described restrictor ring being provided with the second cannelure, be provided with the second sealing ring in the second cannelure, the second sealing ring is inner to offset with restrictor ring outer wall；Install, seal reliably。
