Abstract
The utility model relates to a quick-acting pipeline joint composed of a pipeline joint, a compression nut, a sealing ring, and a tight loop. Each end of the pipeline joint is provided with an external thread, and the compression nut is provided with an internal thread connected with a joint thread. A frustum cone is arranged in each end of the pipeline joint, and a frustum cone is arranged in the compression nut. An upper frustum cone and a lower frustum cone are arranged in the tight loop. The sealing ring is also provided with a frustum cone. The frustum cones are respectively positioned in the frustum cones in the compression nut and in the pipeline. The quick-acting pipeline joint is installed in matching with the frustum cones without needs of tapping and adhibiting, so labor strength and environmental pollution are reduced. The quick-acting pipeline joint is simple, rapid, and reliable to be operated. The quick-acting pipeline joint is particularly suitable for the installation of water supply pipelines, drainage pipelines, steam pipelines, and gas pipelines.
Description
The utility model belongs to pipe coupling or pipe fitting field.Be applicable to variously give, drainage pipe, steam line and gas pipe joint.
Present existing pipe fitting connects, and mainly adopts two kinds of forms of construction work: (1) on-the-spot tapping, (2) bonding processing.Adopt first kind of mode to construct, labor strength is big, and inefficiency adopts second way construction, and the pipe dismounting is wasted time and energy, and maintenance is inconvenient, and certain environmental pollution is arranged.Chinese patent ZL93202997.3 has reported a kind of " exempting from the mantle fiber tube head ", establish the shortcoming that overcomes the aforesaid way construction in certain journey, but this fastening force of exempting from the mantle fiber pipe joint provides by connecting thread fully, positive pressure is big, need bigger fastening force, poor reliability during construction.
The purpose of this utility model is to provide a kind of rapid pipeline joint at the deficiencies in the prior art, need not the tapping field operation, perhaps carry out bonding processing, the double action of the elastic force that adopts pipe coupling frustum itself fastening force when being threaded makes that seal for pipe joints is more reliable, dismounting is more convenient, the rapid pipeline joint of safety and sanitary.
The purpose of this utility model realizes by following technical measures:
The rapid pipeline joint is made up of joint, gland nut, fastening ring and seal ring.Each end of joint is provided with outside thread, gland nut is provided with internal thread, and link to each other with joint screw thread, be provided with frustum in each termination of joint, establish frustum in the gland nut, fastening ring has last frustum and following frustum, seal ring has frustum, place respectively in the gland nut frustum and in the joint frustum and locate, rotatably compress nut during installation, straight tube does not rotate, fastening ring and seal ring are compressed, make its inner ring and straight tube outer wall drive fit, the frustum of seal ring and the frustum of pipe coupling closely cooperate, two frustums of fastening ring, frustum with pipe coupling closely cooperates, frustum in another frustum and the gland nut closely cooperates, and has played the effect of double insurance to preventing seepage, has guaranteed the sealing of pipeline.
Have breach on the fastening ring, be close to the straight tube outer wall when rotatably compressing nut.The last frustum of fastening ring is identical with the tapering of the frustum of gland nut, and the following frustum of fastening ring and the frustum of the seal ring all tapering with the frustum of pipe coupling are identical, and pipe coupling can be designed to straight-through type, Three way type, four-way formula or bending head type.Pipe coupling and gland nut can be made with plastics or metallic material, and seal ring can be made with plastics or rubber.
The utlity model has following advantage: simple in structure, easy construction, it is time saving and energy saving that pipeline connects, improved work efficiency, dismounting is easy to maintenance, safety and sanitary, be applicable to, drainage pipe, steam line and be connected with the installation of various pipelines such as gas pipe line that bigger economic benefit and social benefit are arranged.
Accompanying drawing given below is an embodiment of the present utility model:
Fig. 1 is the structural representation of rapid pipeline joint
(1) pipe coupling, (2) gland nut, (3) seal ring, frustum in (4) fastening ring, (5) gland nut, frustum on (6) fastening ring, frustum under (7) fastening ring, (8) seal ring frustum, (9) are the pipe coupling frustum.
Fig. 2 is the structural representation of fastening ring
(10) breach on the fastening ring
The utility model is described in further detail below in conjunction with accompanying drawing, as shown in drawings, the utility model is by pipe coupling (1), gland nut (2), seal ring (3) and fastening ring (4) are formed, each termination of pipe coupling is provided with outside thread, gland nut is provided with internal thread, and link to each other with joint screw thread, be provided with frustum (9) in each termination of joint, frustum (5) is arranged in the gland nut, fastening ring has last frustum (6) and following frustum (7), seal ring has frustum (8), place in the gland nut (5) respectively and joint frustum (9) in, seal ring (3) is taper, its frustum (8) cooperates with pipe coupling frustum (9), fastening ring (4) two ends are taper, frustum (7) cooperates with pipe coupling frustum (9) under it, last frustum (6) cooperates with frustum (5) in the gland nut, during installation, will put on gland nut, the straight tube of seal ring and fastening ring is inserted an end endoporus of people's pipe coupling, rotatably compress nut, it is connected, with the outside thread of pipe coupling until seal ring, till the frustum of fastening ring and straight tube and pipe coupling forms and closely cooperates.Owing to have breach (10) on the elasticity of seal ring and the fastening ring, rotatably compress nut and can guarantee close-fitting formation, sealingly secure is reliable.
