Abstract
The utility model discloses a thin-wall metal connection pipe, which comprises a thin-wall outer connection pipe and a thin-wall inner connection pipe. The thin-wall metal connection pipe is characterized in that the spigot of the outer connection pipe comprises a threaded port and a tapered transition interface; the faucet of the inner connection hole comprises a frustum port and a threaded transition interface. During connection, the threaded transition interface of the inner connection pipe is matched with the corresponding thread of the threaded port of the outer connection pipe; and the frustum port of the inner connection pipe is connected with the tapered transition interface of the outer connection pipe. By adopting the structure, the thin-wall connection pipe overcomes the disadvantages of the conventional thin-wall connection pipe, such as complex structure, high production cost and difficult processing, and can reduce the material consumption of the pipe joint and greatly reduce the cost of the connector on the premise of ensured sealing reliability. The thin-wall metal connection pipe has the advantages of simple and convenient construction and processing, repeated assembly and disassembly, environmental protection, high durability, etc.
Description
Technical field
The utility model relates to the technical field, particularly thin metallic tubd of the delivery pipe that feeds water.
Background technique
At present, the Placement of conventional metals supply pipe mainly contains and is threaded, blocks pressure connection, welding, bulge loop connection etc.Except that welding manner, other Placements all need the pipe joint link.Its characteristics and deficiency division are as follows: thread connecting mode is reusable, the easy construction in dismounting back, but that its shortcoming is a sealability is unreliable; It is to use the personality card press tool with the interface compacting that card is pressed connection, and advantage is sealing joint reliable performance, easy construction, and shortcoming is can not reuse after interface cost height, the dismounting; Welding manner, advantage are the sealing joint reliable performances, but its shortcoming be the interface cost height, the dismounting after can not reuse, the inconvenience of constructing; Bulge loop Placement, advantage be can reuse after easy construction, the dismounting, sealability is reliable, shortcoming is the interface cost height.More than various Placements all can not accomplish that under the sealability reliable premise link cost is cheap.Thereby causing supply pipe engineering cost height, in fact mainly is connection pipe fitting price height such as pipe joint, causes the popularization of thin metallic tubd, application to be restricted.
The model utility content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art part, proposes a kind of thin-wall metal connecting tube, can accomplish simultaneously can to reuse and process after the dismounting guaranteeing to accomplish that link cost is low under the sealability reliable premise, and it is simple and convenient to construct.
The purpose of this utility model is achieved by the following technical solution: a kind of thin-wall metal connecting tube, include the externally connected pipe of thin-walled and the inner connecting tube of thin-walled, it is characterized in that: the joint socket of externally connected pipe is made of threaded port and circular cone transition interface, and the socket of inner connecting tube is made of circular cone port and screw thread transition interface; When socket joint connects, the cooperation that spins of the screw thread transition interface of inner connecting tube and the corresponding screw thread of the threaded port of externally connected pipe, the corresponding grafting cooperation of circular cone transition interface of the circular cone port of inner connecting tube and externally connected pipe.Further, the range of taper of circular cone transition interface and circular cone port is 0.04-0.25.And the material of externally connected pipe and inner connecting tube can simultaneously or be respectively aluminum alloy body, body of stainless steel, plastic-aluminum combined body.
Such structure has tangible advantage:
1, reliable sealing performance.
2, save traditional metallic pipe coupling, saved cost of material, processing cost greatly, and installation cost has been not high yet.
3, can reinstall, connect, use after the body dismounting.
4, installation, processing are simple and convenient.
Connecting tube of the present utility model is because joint materials consumptive material is few, processing is not difficult, thus cost low be its great advantage, the pipe joint of original metal tube is saved, price just lowers naturally, just can make the engineering cost reduction.Thin metallic tubd just can obtain popularity and use, and just can make huge numbers of families use the water supply line of health, environmental protection.So just good social benefit can be produced, also good economic benefits can be produced simultaneously.
Description of drawings
Fig. 1 is a schematic representation of the present utility model;
Fig. 2 is a partition schematic representation of the present utility model.
Embodiment
Referring to Fig. 1 and Fig. 2, the body of present embodiment adopts thin-wall stainless steel, form by stainless steel externally connected pipe 12 and stainless steel inner connecting tube 22 respectively, wherein the joint socket 1 of externally connected pipe 12 is made of threaded port 11 and middle circular cone transition interface 13, and 2 screw thread transition interfaces 21 by circular cone port 23 and centre of the socket of inner connecting tube 22 constitute.Obviously, each socket or joint socket have included and have been threaded and the circular cone grafting, come down to two kinds of Placements are synthesized on a body.Threaded coupling not only plays the effect of one of them joint, can play the effect of locking circular cone interface simultaneously, and the circular cone interface has good sealability.
When socket joint connects, inner connecting tube 22 spins with externally connected pipe 12 and cooperates, when in the screw thread transition interface 21 precession threaded port 11 and when putting in place, suitably afterburning again the screw-in makes circular cone port 23 produce resiliently deformable, circular cone transition interface 13 in body and produce the bullet shape of changing simultaneously outside body.Material has the stress that will recover original form to exist after resiliently deformable, and this stress can closely stick together circular cone transition interface 13 and circular cone port 23, produces interference fit, forms excellent sealing.Simultaneously, body the time makes the wall thickness of wall ratio circular cone port 23 of circular cone transition interface 13 thicker relatively in design, be subjected to the time spent of doing of tube fluid pressure when mounted joint, circular cone transition interface 13 amount of deformation that thin circular cone port 23 stressed amount of deformation outside body are thicker are big, circular cone port 23 can not separated under the effect of working pressure with circular cone transition interface 13, still closely stick together.Like this, the body fluid pressure produces seepage with regard to not being delivered between the inside and outside interface.
The circular cone interface specification is: circular cone transition interface is identical with the tapering of circular cone port, range of taper is between 0.04-0.25, when actual production is used, externally connected pipe 12 and inner connecting tube 22 can simultaneously or adopt aluminum alloy body, body of stainless steel, plastic-aluminum combined body respectively, to adapt to requirements of different users.
Certainly, only enumerated a kind of preferred implementation here, the protection category that other is equal to, structure roughly the same all should belong to this patent repeats no more here.
