Description

Two screw connection structures of thin-wall stainless steel and pipe joint

Technical field

The utility model relates to thin-wall stainless steel, particularly two screw connection structures of a kind of thin-wall stainless steel and pipe joint.

Background technique

The connection of existing thin-wall stainless steel and pipe joint, general employing is threaded, or connects loose, easily occurs seepage, or complex structure, and processing cost is higher, haves much room for improvement.

Model utility content

The technical problems to be solved in the utility model, is to provide two screw connection structures of a kind of thin-wall stainless steel and pipe joint, and structure is very simple, connects very tight, can reach the good effect that is tightly connected.

For solving the problems of the technologies described above, the technical solution of the utility model is: the two screw connection structures providing a kind of thin-wall stainless steel and pipe joint, Stainless Steel Tube overcoat has nut, the suitable for reading of nut is provided with edge, the formation inner ring surface of going to the bottom on upper edge, Stainless Steel Tube connecting end is provided with outside thread, and cover has seal ring;

Pipe joint connecting end is enlarging shape, and is provided with outside thread, and the inwall root of pipe joint connecting end, is provided with ring surface;

In the middle part of the inwall of pipe joint, be provided with the limited ring of convex, the pipe joint inwall between limited ring and ring surface, is provided with internal thread;

The internal thread of Stainless Steel Tube connecting end and pipe joint is spirally connected, the external thread bolt connection of nut and pipe joint connecting end, inner ring surface and ring surface all with seal ring squeeze flow.

Two screw connection structures of thin-wall stainless steel as above and pipe joint, in the middle part of the inwall of pipe joint, are provided with the cirque body of convex, cirque body are equipped with small sealing ring, and the pipe joint inwall between cirque body and ring surface, is provided with internal thread.

Two screw connection structures of above-mentioned thin-wall stainless steel and pipe joint, structure is very simple, owing to being spirally connected by the internal thread of Stainless Steel Tube connecting end and pipe joint, be connected by the external thread bolt connection of nut with pipe joint connecting end simultaneously, by the Placement of this pair of screw thread, and by inner ring surface and ring surface all with seal ring squeeze flow, make the connection between thin-wall stainless steel and pipe joint very tight, can not seepage be there is, the good effect that is tightly connected can be reached.

Accompanying drawing explanation

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.

Fig. 1 is the longitudinal profile split figure of described embodiment one;

Fig. 2 is the longitudinal sectional drawing of described embodiment one;

Fig. 3 is the longitudinal profile split figure of described embodiment two;

Fig. 4 is the longitudinal sectional drawing of described embodiment two.

Embodiment

Embodiment one:

See Fig. 1, Fig. 2, there is provided two screw connection structures of a kind of thin-wall stainless steel and pipe joint, Stainless Steel Tube 1 can be straight tube or bend pipe, and this sentences straight tube and is described, pipe joint 2 can be that free flow coupling, swan neck joint, T joint are first-class, and this sentences free flow coupling and is described.Stainless Steel Tube 1 overcoat has nut 3, and the suitable for reading of nut 3 is provided with along 4, on along 4 go to the bottom formed inner ring surface 5, Stainless Steel Tube connecting end 6 is provided with outside thread, and cover have seal ring 7; Pipe joint connecting end 8 in enlarging shape, and is provided with outside thread, and the inwall root of pipe joint connecting end 8, is provided with ring surface 9; In the middle part of the inwall of pipe joint 2, be provided with the limited ring 10 of convex, pipe joint 2 inwall between limited ring 10 and ring surface 9, is provided with internal thread.

In using, by when being connected between Stainless Steel Tube 1 with pipe joint 2, be spirally connected with the internal thread of Stainless Steel Tube connecting end 6 with pipe joint 2, the axial feed of limited ring 10 pairs of Stainless Steel Tube connecting ends 6 plays position-limiting action, the external thread bolt connection of nut 3 and pipe joint connecting end 8, form inside and outside pair to be threaded, simultaneously, in inside and outside two rundown process be threaded, inner ring surface 5 and ring surface 9 all form squeeze flow to seal ring 7, seal ring 7 is extruded the joint filling up Stainless Steel Tube 1 and pipe joint 2, thus make the connection between Stainless Steel Tube 1 and pipe joint 2 very tight, seepage can not be there is, the good effect that is tightly connected can be reached.

Embodiment two:

See Fig. 3, Fig. 4, two screw connection structures of a kind of thin-wall stainless steel and pipe joint are provided, the difference of itself and embodiment one is only, in the middle part of the inwall of pipe joint 2, be provided with the cirque body 11 of convex, cirque body 11 is equipped with small sealing ring 12, pipe joint 2 inwall between cirque body 11 and ring surface 9, is provided with internal thread.Like this, when Stainless Steel Tube connecting end 6 is spirally connected with the internal thread of pipe joint 2, the end face of Stainless Steel Tube connecting end 6 pushes against small sealing ring 12, also good seal action is played, thus make the connection between Stainless Steel Tube 1 and pipe joint 2, there is double sealing structure, the better effect that is tightly connected can be reached.

Above-described embodiment is preferred embodiment of the present utility model, and all structures similar with the utility model and the equivalence done change, and all should belong to protection category of the present utility model.
