Abstract

The utility model relates to a pipe joint element, which is connected with a connecting tube, wherein a sealing element and a fastener are sheathed on the top of the connecting tube. The utility model has the advantages of reasonable structure, convenient installation, simple fabrication, low cost, good tightness, unchanged diameter, fluent flow, fast and firm connection between the pipes, etc. The utility model solves the problems of complicated manufacture, troublesome installation, low quality, short service time, etc. of the traditional pipe joint elements, simplifies the technology and the equipment of pipe connection, overcomes the shortcoming that all kinds of pipes are threaded difficultly, reduces the harm of pipe pollution to people, and can also connect pipes conveniently and tightly, so the utility model is an ideal pipe joint matching device.

Description

Pipe joint

The utility model relates to assembling pipe joint, more particularly is the pipe joint of the linkage structure that is used for being connected as a single entity between the pipeline.

Pipeline known to the common people, especially water pipe has galvanized pipe, aluminium-plastic composite pipe, Stainless Steel Tube etc., galvanized pipe corrosion-resistant, the easy dirt that gets rusty, the long-term use contained harmful heavy metal, encroaching on people's health, its Placement majority is that sealing strip adds and is threaded, and its link need be made screw thread on main pipe, processed complex, sealing is poor, working life is short, and along with the raising of people's living standard, this galvanized pipe and pipe fitting thereof will be eliminated; Aluminium-plastic composite pipe poor heat resistance, its Placement adopt internal layer to be tightly connected, and existing link internal diameter is less, and flow is obstructed, and causes local compression excessive, explosion easily, and the processed finished products rate of its link is low, difficult quality guarantee; Stainless Steel Tube has the advantage in the use, and existing only have the employing thread connecting mode, because it is big to make a difficulty on main pipe, both caused waste of raw materials easily, has problems such as sealing difference again.At present the link that is complementary is not with it arranged as yet, hindered applying of it, therefore, present pipeline and link thereof are in the usage requirement of not satisfying people in varying degrees.

The purpose of this utility model is to provide a kind of can eliminate above-mentioned shortcoming, have rational in infrastructure, easy for installation, processing is simple, with low cost, sealing is strong, latus rectum is constant, flow is unobstructed, can be fast, securely with the pipe joint of characteristics such as pipeline connection.

It is that formations such as connecting tube, Sealing, fastening piece, link are arranged that this reality has novel pipe joint, it be with Sealing successively on the top of connecting tube, fastening piece is connected with link, wherein Sealing is preferably selected the seal ring of macromolecular material time processing moulding for use, as rubber ring etc.Fastening piece metal material processing moulding, as pad or snap ring etc., link with the nut of connecting tube threads engaged, connecting tube can be made into single-pass, curved logical, many different shapes such as logical according to usage requirement, the metal material processing moulding of nut and connecting tube, wherein connecting tube top internal diameter leaves an inclined-plane, made outside thread on its external diameter, seal ring and pad withstand on successively on this inclined-plane and lock by nut pressure with snap ring, main pipe and link are closely as one, prevent the pipeline junction liquid spill.Described connecting tube is leaving a concave station with the main pipe joint, make the connecting tube internal diameter with connection the main pipe internal diameter be consistent, be convenient to keep latus rectum constant in the main pipe insertion connection pipe fitting, on the internal diameter of nut, made internal thread, its root leaves an inclined-plane, be convenient to pin snap ring, play the fit sealing effect, when link uses, on main pipe, put earlier seal ring, pad, snap ring, nut, insert in the connecting tube again, rotary nut is threaded with connecting tube, the propagation of pressure of whole pipe link is to compress seal ring in inclined-plane, connecting tube top by pad, and snap ring is tightly connected together connecting tube by pressure self-locking chucking in inclined-plane in the nut securely with main pipe.

Further specify optimum scheme of the present utility model in conjunction with the accompanying drawings:

Shown in Fig. 1-6, on the external diameter of the top of connecting tube 1, made outside thread 9, stayed an inclined-plane 6 on its internal diameter, a concave station 7 has been arranged at the joint of itself and main pipe 10, the degree of depth of this concave station 7 is by connection main pipe 10 thickness of pipe decision, makes it keep being consistent with the main pipe internal diameter and be as the criterion.Connecting tube 1 can according to usage requirement be processed into single-pass, how logical or curved different shape such as logical shown in Fig. 7-10.It is to be connected with nut 5 according to being with seal ring 2, pad 3, snap ring 4 on the top of connecting tube 1, making internal thread 9 on the internal diameter of nut 5 cooperates with outside thread 9 on the connecting tube external diameter, root bottom part leaves an inclined-plane 8 in nut 5, be convenient to withstand snap ring 4, make its self-locking chucking, make the main pipe 10 that connected like this it goes without doing that processing just can be combined closely with connecting tube 1.

Pipe joint of the present utility model solved for a long time conventional pipelines link processed complex, trouble has been installed, of poor quality, problem such as the life-span is short, simplified the Processes and apparatus that pipeline connects widely, especially overcome the shortcoming of various pipeline mantle fiber difficulties such as Stainless Steel Tube, played decisive role for promoting stainless steel pipeline, reduce the harm of pipeline pollution to human body, can be efficiently and easily the pipeline of various tubing closely being connected, is the match equipment that desirable pipeline connects.
