Abstract
The utility model relates to a pipeline quick connecting device, promptly one with pipeline non-threaded connection, the frictional resistance who produces through the inside and outside pipeline realizes sealed and anti-skidding pipe connection spare, respectively has a frustum shape boss in the both ends cavity of its casing of characterized by, and fastening nut has interior toper opening, has the outer sealing ring and the tighrening ring along of toper when being connected with casing screw thread, because the pressure of compressing tightly and intraductal medium of nut, makes the joint punishment can not produce the osmosis phenomenon at all. The utility model has the advantages of simple and reasonable structure, do not do any processing to the pipeline during the use, therefore quick convenience is particularly suitable for the connection and the installation to thin wall aluminum alloy pipe.
Description
The utility model relates to a kind of pipeline Quick Connect Kit, and promptly a kind of and pipeline be non-threaded to be connected, and realizes the pipe joint that sealing and antiskid are moved by the surface friction drag of the inside and outside generation of pipeline.
According to patent documentation is retrieved, the quick link of the pipeline of non-threaded connection has as if the patent No. is the joint of 89107993.9 pipelines, the patent No. is 87103263 self-tightening pipe coupling, the patent No. is 85200482 F type sealing block quick coupling pipe fitting, aforementioned three patents have only considered to utilize the pressure of medium in the pipe to realize that sealing and anti-pipeline slide, and the patent No. is that 90217092.9 a kind of pipe joint and the patent No. are that 89220025.1 pipeline coupling arrangement has then only considered to utilize external force to realize that sealing and anti-pipeline slide.In fact, the simple interior pressure medium of pipe that relies on realizes that sealing and anti-pipeline slide, selection to tubing requires very strict, when being used for the smooth tube connection, the pipeline obscission will appear when pressure was higher, when pressure medium is lower than 0.1mPa in the pipe, leakage phenomenon is comparatively serious, and rely on external force to realize that sealing and anti-pipeline slide merely, though the seepage phenomenon when pressure medium is low in the shutoff pipe preferably, but when pressure medium is too high in the pipe, because the limited pipeline that causes easily of surface friction drag comes off.
The purpose of this utility model is to provide a kind of and utilizes artificial external force to make Sealing and fastening piece and pipeline produce frictional force, also utilized simultaneously pressure medium in the pipe to increase the frictional force of Sealing and pipeline, the pipe internal pressure is big more, sealing, the ready-package pipe friction joint that anti-slide performance is good more.
The purpose of this utility model is to realize by such structure, be that it is by joint housing, seal ring, retaining ring, fastening nut are formed, it is characterized in that in the two ends cavity of joint housing a taper type boss being arranged respectively, fastening nut has the inner conical opening, be threaded with the joint two ends, seal ring and retaining ring all have the taper outer, and the conical surface with the tapered opening of taper type boss and fastening nut coincide respectively.
Said structure of the present utility model can further specify by accompanying drawing:
Accompanying drawing is the schematic representation that partly cuts open of the present utility model.
Referring to accompanying drawing: the figure middle joint is made up of housing 1, elastic sealing ring 2 and retaining ring 3 and fastening nut 4.During use, in pipeline to be connected 5 insertion tube joints, the nut 4 of screwing on makes the conical surface of the taper outer of seal ring corresponding to taper platform convex platform 6, and the conical surface of retaining ring 3 is tightened corresponding to the inner conical opening 7 of fastening nut 4.At this moment seal ring 2 and retaining ring 3 are squeezed and are close on the conical surface.When in the pipe medium being arranged, the pressure of its generation is close on the tube wall root of seal ring, and pressure is big more, and pasting tightly more is that surface friction drag is big more, thereby the seepage phenomenon will never take place.
Compare with prior art, the utility model structure is more simple, rationally, easy to install, pipeline is carried out in the situation of any processing not needing, pipeline is directly inserted in the frictional resistance joint, and the fastening nut at the joint two ends that screw up with a wrench can use, and has improved significantly installation efficiency, has saved mounting cost. In addition, the utility model can also be widened the scope of application of thin-wall aluminum alloy pipeline, make it can not only be in urban water supply, the air feed engineering obtains using, and also can use in industrial production and agriculture slight irrigation, compares with the coating steel pipe of present use, can save pipeline transportation expense 70～80%, reduce pipeline engineering cost 30～40%, and attractive in appearance antirust, durable in use.
