Abstract
The utility model discloses a quick pipe joint, which comprises two hoop plates buckled on the outer wall of the end of a pipe through Haff structures. Concave-convex matched release-proof structures are arranged between the two sides of the buckled surfaces of the hoop plates and the outer wall of the end of the corresponding pipe. By adopting the hoop type pipe joint, welding is not needed any more between the pipe joint and the pipe, so the installation speed is high; the number of fasteners for connecting is greatly reduced, so the operation difficulty is reduced, and the cost of the pipe joint is lowered; and because of the release-proof structures, the pull release resistance and the bearing performance of the pipe are greatly improved.
Description
Technical field
The utility model relates to a kind of pipe joint of fast demountable, belongs to pipe fitting interconnection technique field.
Background technique
What can repeat to load and unload in the existing pipe fitting Placement mainly be that flange connects, and exactly flange plate is placed on the centre of a pair of flange on two place's mouths of pipe, with the bolt tension two pipe fittings is connected then, becomes a kind of dismountable Placement.But in practical operation, the flange connection exists construction bolt many, and complex operation, slow-footed defective also need be welded at flange and pipe fitting joint for the occasion that some sealing requirements is higher, and not only the cost height also pollutes the environment.It is that " 200920025244.X ", name are called the patent of " Theft-proof collar clamp " that China national Department of Intellectual Property discloses the patent No. in 2010-03-03, adopt the pipe joint of clamp band type, though it is easy to connect, the bolt quantity that connects usefulness also significantly reduces, but when internal tube pressure was excessive, pipe fitting and joint were thrown off easily, cause leakage accident, its sealability, support performance and taking off property of tension all have deficiency, especially are embodied in the connection of large-diameter pipe spare.
Summary of the invention
Problem to be solved in the utility model just provides a kind of quick coupling simple in structure, has that auxiliary component is few, easy to operate, fast, pollution-free, the reusable characteristics of dismounting speed.
For solving the problems of the technologies described above, the utility model adopts following technological scheme: a kind of quick coupling, comprise that two are fastened on clip sheet on the pipe fitting end outer wall with half slide structure, is characterized in that: also be provided with the concavo-convex disconnecting prevention structure that matches between the buckling surface both sides of clip sheet and the corresponding pipe fitting end outer wall.
Further, described disconnecting prevention structure comprise that the ring-type card that is located at clip sheet buckling surface both sides is protruding, be located on the pipe fitting end outer wall and with the protruding corresponding annular recess of described ring-type card.
Further, the protruding quantity of ring-type card of clip sheet buckling surface one side is 1-3.
Further, the protruding sectional shape of ring-type card is trapezoidal, semicircle or rectangle.
Further, described pipe fitting is three-way pipe, straight tube or valve.
Further, the middle part of clip sheet buckling surface be provided with for seal washer embed cavity, pipe fitting end is inserted on the seal washer body, and after two clip sheets fastened, the outer ring portion elastic compression of seal washer realized line seal between cavity internal face and pipe fitting end outer wall.
Further, clip sheet two ends stretch out and form the lug that connects usefulness, are convenient to the connection of two clip sheets.
Further, the lug of two clip sheet corresponding end connects and locking by fastening piece.
The beneficial effects of the utility model; Adopt the pipe joint of clamp band type, no longer need welding between pipe joint and the pipe fitting, installation rate is fast; Required connection significantly reduces with fastening piece quantity, has not only reduced operation easier, and therefore the cost of pipe joint also descends; The taking off property of tension that is arranged so that pipe fitting of disconnecting prevention structure, support performance improve greatly; The utility model is guaranteeing also to have taken into account sealing function in the connection fast, and it is reliable, stable that pipeline connects; Because fastening piece quantity is few, the pipe joint dismounting is also very convenient, is convenient to the cleaning and the replacing of pipeline.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is the overall structure schematic representation of the utility model clip sheet;
Fig. 2 is the A-A sectional drawing of Fig. 1;
Fig. 3 is the connection diagram of the utility model clip sheet and pipe fitting;
Fig. 4 is the fastening structure schematic representation of two clip sheets.
Embodiment
As shown in Figure 1 to Figure 3, the utility model is a kind of quick coupling, comprise that two are fastened on clip sheet 1 on the pipe fitting 3 end outer walls with half slide structure, also be provided with the concavo-convex disconnecting prevention structure that matches between the buckling surface both sides of clip sheet 1 and the corresponding pipe fitting 3 end outer wall; Disconnecting prevention structure comprises that the ring-type card that is located at clip sheet 1 buckling surface both sides is protruding 10, be located on the pipe fitting 3 end outer wall and with described ring-type card protruding 10 corresponding annular recess 31; Protruding 10 quantity of ring-type card of clip sheet 1 buckling surface one side are 1-3, the middle part of clip sheet 1 buckling surface be provided with for seal washer 2 embed cavity 12, pipe fitting 3 ends are inserted on seal washer 2 bodies, after two clip sheets 1 fastened, the outer ring portion elastic compression of seal washer 2 realized line seal between cavity 12 internal faces and pipe fitting 3 end outer wall.
As shown in Figure 4, in the both sides of clip sheet 1 buckling surface a ring-type card protruding 10 is set respectively, two clip sheet 1 correspondences are fastened on pipe fitting 3 ends, ring-type card protruding 10 snaps in the ring-type draw-in groove, use two groups of bolts 4, nut 5 respectively lug 11 serial connections at upper and lower two clip sheet 1 two ends to be tightened up, compare original flange and connect, bolt quantity significantly reduces; And, when connecting fast, also taking into account sealing function, seal washer 2 is owing to be subjected to the two the extruding of groove internal face and pipe fitting 3 end outer wall, thereby the sealability of pipe fitting 3 and pipe joint joint is more good.Above-mentioned pipe fitting 3 types can be three-way pipe, straight tube or valve, and the sectional shape of ring-type card protruding 10 can be designed to be trapezoidal, semicircle or rectangle; If pipe fitting 3 distances, the caliber that connect are big, the quantity of ring-type card protruding 10 can suitably increase, and adopts 2 or 3 ring-type cards protruding 10, has not only solved the shortcoming that existing pipe fitting 3 is easily deviate from pipe joint, can improve simultaneously the support of pipe fitting 3 again, it is stable more, reliable to make pipeline connect.
The foregoing description only is an optimal way of the present utility model, bolt, the nut class fastening piece that the utility model adopts is a kind of in the locking mechanism, certainly those skilled in the art are when considering factor such as operation convenience, product cost, can select other locking mechanisms for use, but only otherwise break away from spirit of the present utility model, all should belong to the defined scope of the utility model claims.
