Abstract
The utility model discloses an internal thread locking connector. Internal threads of a pipe connector body are matched and connected with outer threads of a locking thread sleeve, and a circlip is arranged in a circular arc-shaped groove arranged in a pipeline and is corresponding to a conical inner hole of the locking thread sleeve. A conical sealing ring is sheathed on the pipeline and is correspondingly arranged in a conical table hole of the pipe connector body, and an O-shaped sealing ring is correspondingly arranged on a step of the inner hole of the pipe connector body. The utility model has the characteristics of reasonable structure, rapid and convenient assembly and disassembly, reliable connection, double seal, etc., and can be made into connectors for connecting straight through joints, elbows, tee joints, cross joints and valves. The utility model is suitable for the installation and the connection of various pipeline systems and is also suitable for the connection of a plurality of thin-wall pipeline systems.
Description
The utility model belongs to a kind of pipe joint, particularly a kind of internal thread locking connecting head.
Present pipe joint requires dismounting efficient and convenient, good sealing effect, as the patent No. be: ZL94201138.4, name is called: the utility model patent of " fast holding pipe joint ", it is characterized in that: there is outside thread each termination of three-way pipe, gland nut has internal thread, O-ring seal and seal ring are taper type, in each termination of three-way pipe a frustum is arranged all, gland nut has a frustum, and the frustum of sealer and the frustum of seal ring place respectively in the frustum of each the termination frustum of three-way pipe and gland nut.This kind need be on pipeline the power that tightens up of the self-locking joint of threading inwardly tighten up by coupling nut extruding locking ring fully and block pipeline, and in locking by locking ring crush seal ring, reach the sealing that pipeline connects.But this kind structure is owing to provide the power of tightening up by the attaching nut fully, and positive pressure is big, during construction, must apply the bigger power that tightens up, just can reach the purpose of locking, installation reliability is poor, in addition, even locking ring tightens up pipeline, and the crush seal ring reaches conical surface seal, but the end face of pipeline is difficult to reach contact with pipe joint endoporus ear end face and obturages in practice, so the pipe joint endoporus has the surface of exposing aluminium to contact with water, cause the pipe fitting heavy corrosion, reduce sealing effect and working life.
In view of the foregoing, the purpose of this utility model is to provide a kind of dismounting efficient and convenient, and double seal connects reliable internal thread locking connecting head.
The purpose of this utility model is achieved in that it is made up of union body, locking swivel nut, jump ring, cone-shaped sealing ring, O-ring seals, inside, union body two ends is symmetrical arranged internal thread, circular cone hole, cylinder endoporus A and interior step hole successively, locking swivel nut one end is square toes, the other end is an outside thread, inside sets gradually cylinder endoporus B and circular cone endoporus, and the internal thread of union body is connected with the outside thread of locking swivel nut; Jump ring is an O shape jump ring, and opening is arranged, and is arranged in the arc-shaped groove of pipeline, the circular cone endoporus of corresponding locking swivel nut; Cone seal is equipped with conical table top, cylinder table and endoporus, is enclosed within on the pipeline, and correspondence is arranged in the circular cone hole of union body; The O-ring seals correspondence is arranged on the endoporus step of union body.
Union body can be the jointing of straight-through connecting head, elbow connecting head, threeway connecting head, four-pass connecting joint and valve.Union body and locking swivel nut can be made with plastics, aluminum alloy, Cuprum alloy, stainless steel and other metallic material, and cone-shaped sealing ring and O-ring seals can be made with plastics or rubber.
When pipeline is connected with union body, the groove of elder generation's one circular arc of roll extrusion on the termination outer surface on the pipeline, on pipeline, be inserted in the locking swivel nut then, jump ring is snapped in the groove of circular arc of pipeline, cone-shaped sealing ring is enclosed within on the pipeline, and on the endoporus step of union body, be encased inside O-ring seals, in endoporus with connecting tube insertion tube fittings body, in the internal thread with locking swivel nut spinning in pipe fittings body, along with screwing of locking swivel nut, jump ring enters in the round taper hole of locking swivel nut and reaches self-locking and hold pipeline tightly, the tapered bore face that is put by locking screw promotes jump ring drive pipeline and produces displacement together in the union body endoporus simultaneously, and locking swivel nut crush cones V-shaped ring, the conical surface of cone-shaped sealing ring is close on the conical surface of union body endoporus, simultaneously also with the pipeline external surface crush seal, produce the first road pipeline conical surface seal form, meanwhile also because the displacement forward of pipeline, make the end face extruding O-ring seals of pipeline, produce the second road pipeline end face seal form, realize the double seal effect, guarantee the reliability and the firm Security that is connected of sealing.
The utility model is compared with existing connecting head, and the internal thread of union body is connected with the outside thread of locking swivel nut; Jump ring is arranged in the arc-shaped groove of pipeline, the circular cone endoporus of corresponding locking swivel nut; The cone-shaped sealing ring correspondence is arranged in the circular cone hole of union body; The O-ring seals correspondence is arranged on the endoporus step of union body.Have rational in infrastructurely, dismounting is efficient and convenient, connects reliably, and characteristics such as double seal are applicable to that the installation of various pipe-line systems connects, and also are suitable for the connection of some sheet-metal duct systems.
