The left part outer wall of described left joint is octagon, and the right part outer wall of right connector is octagon, and the outer wall of loose joint sleeve is regular hexagon or octagon.
The beneficial effects of the utility model are:
It can avoid the secondary pollution of tap water, can extend the working life of loose joint simultaneously.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the schematic perspective view of right connector;
Fig. 3 is the schematic perspective view of left joint;
Structural representation when Fig. 4 is the utility model use.
In figure: 1, loose joint sleeve; 11, loose joint sleeve back-up ring; 2, left joint; 21, left joint outside thread; 22, left joint internal thread; 3, right connector; 31, right connector back-up ring; 32, right connector internal thread; 4, right stainless steel bushing pipe; 41, the left flange of right stainless steel bushing pipe; 42, the right flange of right stainless steel bushing pipe; 5, left stainless steel bushing pipe; 51, the right flange of left stainless steel bushing pipe; 52, the left flange of left stainless steel bushing pipe; 6, O RunddichtringO; 7, concrete.
Embodiment:
Embodiment: see Fig. 1, shown in 2, inner liner stainless steel loose joint pipe fitting, comprise loose joint sleeve 1, left joint 2 and right connector 3, on loose joint sleeve 1, form the loose joint sleeve back-up ring 11 that is positioned at loose joint sleeve 1 right opening, on right connector 3, form right connector back-up ring 31 and right connector internal thread 32, right connector 3 sleeves are in loose joint sleeve 1, the right side of right connector back-up ring 31 is pressed on the inwall of loose joint sleeve back-up ring 11, the outer wall right part of left joint 2 forms left joint outside thread 21, on the inwall of left joint 2, form left joint internal thread 22, the right part opening of left joint 2 forms step 23, left stainless steel bushing pipe 5 right-hand members form the right flange 51 of left stainless steel bushing pipe, left stainless steel bushing pipe 5 left ends form the left flange 52 of left stainless steel bushing pipe, the right flange 51 of left stainless steel bushing pipe is pressed on step 23, left stainless steel bushing pipe 5 sleeves are in left joint 2, between left stainless steel bushing pipe 5 and the inwall of left joint, be filled with concrete seven,
The left part opening of right stainless steel bushing pipe 4 forms the left flange 41 of right stainless steel bushing pipe, the right part opening of right stainless steel bushing pipe 4 forms the right flange 42 of right stainless steel bushing pipe, right stainless steel bushing pipe 4 sleeves in right connector 3 and the left flange 41 of right stainless steel bushing pipe be pressed on the left side of right connector, between right stainless steel bushing pipe 4 and right connector 3, be filled with concrete seven; O RunddichtringO 6 is clamped between the left flange 41 of right stainless steel bushing pipe and the right flange 51 of left stainless steel bushing pipe, and left joint 2 is screwed together with loose joint sleeve 1 by left joint outside thread 21.
