Abstract
The utility model relates to a pipe joint, which is suitable for various lining plastic aluminium pipes and aluminium plastic pipes. In order to overcome the defects of additional configuration for an opening clamping ring, more complicated structure, high cost, easy aging sealing ring, loosen connection, poor pressure bearing of a pipe joint in the prior art, the pipe joint and a pipe which is connected are connected in concave-convex engagement. The pipe joint and the pipe to be connected are fixed by nuts of pipe fittings. The utility model has the advantages of good sealing performance, high pressure bearing, simple structure and low cost.
Description
The utility model relates to a kind of pipe joint that is applicable to various plastic lining aluminium pipes and plastic-aluminum pipe.
Existing pipe joint is that straight tube connects, no angle of inclination, so just need dispose slotted collar, rubber seal in addition, structure is complicated, relative cost is just high, seal ring is easily aging to have caused the connection of pipe joint not firm, bearing capacity is poor, and it has a plurality of annular grooves and O RunddichtringO at insertion portion as " quick coupling " of Chinese patent 97203906 bulletins, has above-mentioned problem too.
The utility model be to provide a kind of simple in structure, cost is low, connection is tight, good airproof performance, pipe joint that bearing capacity is big.
This practicality adopts following technology to achieve the above object: it is that concavo-convex coincideing links to each other that pipe joint is joined two pipes together with quilt, and both fix by tube part nut, and the pipe fitting nut inner wall is corresponding to the inner concavity that convexes into of pipe.
In order to reach better effect, pipe joint, pipe and pipe fitting nut three's camber is corresponding, is 45 °～120 °, is preferably 60 °.
The utility model has solved in the prior art plastic lining aluminium pipe and the Aluminium-plastic pipe joint sealing is poor, connect not firm difficult problem to be solved always, it with pipe joint, joined two pipes together and pipe fitting nut three's Placement is designed to have certain camber, can effectively the three be combined closely, good airproof performance, bearing capacity height, it is simple in structure, cost is low.
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is the structural representation of the utility model pipe joint.
Concave 60 ° the taper of 3 one-tenth of pipe joints, pipe 2 is corresponding to 3 one-tenth one tapers to 60 ° of evaginations of pipe joint, with both sockets, in the indent taper corresponding to 2 one-tenth 60 ° on pipe of pipe fitting nut 1 inwall of external tapping one side, pipe fitting nut 1 slides to pipe joint 3, screws both fixedly connected.
The sphere of pipe joint 3 for concaving, 3 one-tenth one cambered outwards spheries of pipe 2 respective tube joints are coincide both, and the inwall of pipe fitting nut 1 is corresponding to 2 one-tenth one spheries of pipe, and pipe fitting nut 1 is tightened pipe 2 and pipe joint 3.
That pipe joint can be is straight-through, straight-through or the like the various forms of conversion of threeway, elbow, reducing, all drops within the protection domain of the present utility model.
