Abstract
The utility model relates to a ring pressure reinforced thin-wall metal pipe fitting, which mainly solves the problem of high costs and inconvenient operation of connecting metal pipe fittings and pipe. The technical scheme of the utility model is that on the opening of the connection pipe is disposed a stepped ring pipe, which comprises an inclined part and a straight part. One caliber of the inclined part is smaller than the other one of the same, and the inclined part is inclined downwards and towards the outside along the inner wall of the connection pipe. On the straight part are arranged in sequential order an inner convex ring groove, an outer convex ring groove, a steeped ring pipe, an inner convex ring groove and an outer convex ring groove, which together form a ring pressure reinforced structure. The utility model has advantages of excellent sealing performance, strong compression performance, firm structure, easy operation, low costs, and the product is an innovation in the field of pipe fittings.
Description
One, technical field
The utility model relates to pipe fitting, the pressure reinforced thin-wall metal pipe of particularly a kind of ring.
Two, background technique
Existing metallic conduit Placement, generally be by screw thread or be welded to connect, this linkage structure is connected with the hot melt of plastics to be connected with glue to be compared, the one, processing intensity is big, installment work efficient is lower, and technology is very complicated, and pipe fitting need be reprocessed just and can be met connection request, production process is many, loses time.Therefore it is lower to compare the force rate that constitutes competition with plastic pipe, for addressing this problem, some metal pipe elements by the groove that carries or draw-in groove strengthen with pipeline between be connected, but so often install cumbersomely, operation is more, and the other metal pipe element is taked flanged connecting structure, though it is simple many on installation steps, but increased cost, caused and to use in a large number, so imperative to the improvement of metal pipe element.
Three, model utility content
At above-mentioned situation, for overcoming the prior art defective, the purpose of the utility model just provides the pressure reinforced thin-wall metal pipe of a kind of ring, can effectively solve the trouble that is connected of metal pipe element and pipeline, the problem that cost is high, the technological scheme of its solution is, joint body oral area has the stepped shaft endless tube, the stepped shaft endless tube has italicized item and stretched part, italicized item one port footpath is less than the bore of the other end, and italicized item is to be downward outer incline shape along the joint inboard wall of tube body, on the stretched part convex annular groove and evagination annular groove is arranged successively, stepped shaft endless tube and convex annular groove, the evagination annular groove constitutes ring and presses reinforced structure.The utility model good seal performance, compression resistance is strong, is connected firmly, and is simple to operation, and cost is low, is the innovation on the pipe fitting.
Four, description of drawings
Fig. 1 is a structure sectional view of the present utility model (partly cuing open).
Fig. 2 is connected sectional view (partly cuing open) for the utility model and pipeline.
Five, embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.
Provide by Fig. 1-Fig. 2, the utility model structure is that joint body 1 oral area has the stepped shaft endless tube, the stepped shaft endless tube has italicized item 2a and stretched part 2b, italicized item one port footpath is less than the bore of the other end, italicized item is to be downward outer incline shape along the joint inboard wall of tube body, on the stretched part convex annular groove 3 and evagination annular groove 4 are arranged successively, stepped shaft endless tube and convex annular groove, evagination annular groove constitute ring and press reinforced structure.
In order to guarantee using effect, said convex annular groove 3 is the arc to outer lug, and first seal ring 5 is arranged in the convex annular groove; Said evagination annular groove 4 is the arc to outer lug, and second seal ring 6 is arranged in the evagination annular groove, and the groove depth of evagination annular groove is slightly less than the internal projecting ring groove depth, and arc length is slightly less than the arc length of convex annular groove.
Use condition of the present utility model is, earlier first seal ring 5 and second seal ring 6 are arranged at respectively in convex annular groove 3 and the evagination annular groove 4, then, there is the body 8 of double convex ring to pass in the oral area of second seal ring 6 and first seal ring, 5 insertion joint bodys 1 oral area, the oral area of body 8 is plugged in the stepped shaft endless tube, and first bulge loop 7 of body 8 and second bulge loop 9 are plugged in first seal ring 5 and second seal ring 6.As shown in Figure 3, the employing instrument encircles the pressure reinforcement to internal projecting ring groove 3 and evagination annular groove 4 both sides, ring is pressed to add and is forced inside and outside bulge loop groove and first, second supporting seal ring to be gathered to first, second bulge loop contraction of body gradually, and the three is combined closely, form the reinforced structure that connects and seal, and then reached the purpose that further is tightly connected.In addition, encircle pressure simultaneously in the utility model port position and strengthen, jointing is further sealed.
It is to be noted that the foregoing description does not limit the utility model in any form, all technological schemes that form obtained of taking to be equal to replacement or equivalent transformation all drop within the protection domain of the present utility model.
The utility model has substantive distinguishing features and progressive with respect to prior art, and is specific as follows:
1, the utility model has biconvex annular groove (being convex annular groove and evagination annular groove) and supporting sealing ring (i.e. first sealing ring and second sealing ring), so that the utility model can be connected with the body that oral area has a double convex ring (first bulge loop be connected bulge loop); The mode that the triple seal that the utility model adopts first, second bulge loop three of inside and outside bulge loop groove and first, second sealing ring of being connected and body to combine closely connects, and the sealing ring place adopts the curve-seal structure, greatly improved and adopted sealing property of the present utility model, compressive property and the performance that is connected firmly.
2, in the installation process, the body that only needs oral area to be had double convex ring inserts the utility model, and tool using encircles pressure then, makes body and the utility model produce the ring compressive strain, and is simple to operation, saving of work and time.
3, in the course of working, the utility model and oral area have the body of double convex ring itself not need to carry out damaging reprocessing, have guaranteed quality of product and safe in utilization to greatest extent.
The utility model is simple and practical, and sealability is good, firm and reliable connection, and long service life, and be easy to manufacturing, and reducing cost, economic and social benefit is remarkable.
