Abstract
The invention relates to a shape memory alloy pipe connection device which aims at solving the technical problem that an existing pipe connection technology and product cannot be applied to a high-temperature and high-pressure environment simultaneously. In order to solve the technical problem, the shape memory alloy pipe connection device is adopted and comprises a pair of semicircular hoops buckled to the pipe ends of a pipe, shape memory alloy short pipes arranged in cavity bodies of the hoops and a metal pipe, and the end of the metal pipe is provided with more than one annular groove. The two ends of each hoop are each provided with two or more bolt holes for fixation, and the two sides of the attachment face of the hoops are each provided with more than one annular groove structure. The shape memory alloy short pipes and in large interference amount fit with the connected metal pipe through an shape memory effect, sealing connection is achieved, and the characteristics of being high in connection strength, good in sealing performance, resistant to corrosion, resistant to high temperature (larger than or equal to 300 DEG C) and resistant to high pressure (larger than or equal to 63 MPa) are achieved; and as the hoops are designed, and inner cavities of the hoops are in tight fit with the shape memory alloy short pipes, it is promoted that the better effect of sealing with the metal pipe can still be kept when shapes of the shape memory alloy short pipes are changed.
Description
Technical field
The present invention relates to a kind of assembling pipe joint, is specifically a kind of marmem pipe road connection set.
Background technique
At present in industries such as space flight, petrochemical industry and boats and ships, need fed sheet of a media under high-temperature high pressure, but be at present that the groove pipe interconnection technique of traditional interconnection technique or advanced person all cannot realize using under high temperature and high pressure environment, this technological deficiency causes Industry Quick Development to be seriously obstructed simultaneously.
Although existing a kind of pipe joint adopting memory alloy to carry out pipeline connection achieves the connection of pipeline, but be limited by existing pipeline and be mostly ellipticity, and the outer wall surface roughness of pipeline is larger, direct like this memory alloy short tube to be connected with pipeline outer wall, although achieve interference to connect, but still cannot guarantee oval due to outer diameter tube and that surface roughness is larger impact and cause sealing poor, also cannot guarantee to possess enough compressive strengths for using under hot environment, if and once the temperature difference changes can there is expanding causing and cannot seal further in memory alloy pipes.
Summary of the invention
The object of the invention is in order to cannot simultaneously realizing of solving that existing pipeline connection technology exists be applied to high temperature and high pressure environment under the technical limitation that uses, and provide a kind of can have concurrently simultaneously high temperature high voltage resistant marmem pipe road connection set.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions:
A kind of marmem pipe road connection set, it comprise be fastened on pipeline pipe end place for a pair semicircle clip, be arranged on marmem short tube in the middle of clip in concave cavity and metallic conduit, described clip, is characterized in that: clip buckling surface place is provided with the above annular boss of at least twice.
In order to reach better sealing effect, in the further detailed structure of the present invention, also have following characteristics: described marmem short tube shape ringwise, the change that the memory effect utilizing memory alloy can possess according to it under difference variation realizes size realizes with metallic conduit interference fit and then realizes sealing by force.
In order at low temperatures still there is better sealing effect, in the further detailed structure of the present invention, also there is following characteristics: the inner chamber of described clip and the external diameter of memory alloy short tube are designed to drive fit, impel marmem short tube at low temperatures size expansion time cannot be expanding to reach the object still playing sealing by the restriction of clip.
In the further detailed structure of the present invention, also there is following technical characteristics: the end of described metallic conduit is provided with groove above together.
Compared with prior art, advantage of the present invention and good effect are: owing to present invention employs said structure, only memory alloy pipeline need be carried out temperature difference adjustment and just can realize being connected or dismounting with the quick of metallic conduit during Pipe installing.Adopt this Placement time saving and energy saving, greatly increase working efficiency, reduce cost.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention, be briefly described to the accompanying drawing used required in embodiment below, apparently, accompanying drawing in the following describes is some embodiments of the present invention, to those skilled in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.

Embodiment
For making the object, technical solutions and advantages of the present invention clearly, be clearly and completely described technological scheme of the present invention below in conjunction with accompanying drawing, obviously, described embodiment is the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
See Fig. 1-Fig. 6, a kind of marmem pipe road of the present invention connection set comprises clip 10, marmem short tube 40 and metallic conduit 50 and forms.
First by two sections of metallic conduit 50 centering location when this invention uses, then the centre will the marmem short tube 40 of Shape-based interpolation memory alloy being adopted to be enclosed within two metallic conduits 50, the initial inside diameter of marmem short tube 40 is set to the external diameter being less than metallic conduit 50, in expanding state under low temperature, make the internal diameter of memory alloy short tube 40 slightly larger than metallic conduit 50 external diameter, after two metallic conduits 50 being inserted location from the two ends of marmem short tube 40 during installation, marmem short tube 40 is impelled to recover original-shape by heating apparatus and metallic conduit 40 realizes interference fit and then realizes being tightly connected of pipeline.And then clip 10 is fastened on the groove 60 li of metallic conduit 05, two ends realize reinforcing by bolt, object be in order to be reduced to when Environmental Conditions temperature can make marmem short tube 40 because of difference variation size expansion time, by the pretightening force of clip 10 reach force marmem short tube 40 cannot size exaggeration object, the internal diameter of clip 10 is designed to the external diameter being less than marmem short tube 40, marmem short tube 40 forms drive fit with the inner chamber of clip 10 thus reaches double seal, no matter whole like this device is all can realize the effect that is tightly connected preferably at low temperatures or under high temperature.
Last it is noted that above embodiment is only in order to illustrate technological scheme of the present invention, be not intended to limit; Although with reference to previous embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that: it still can be modified to the technological scheme described in previous embodiment, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of embodiment of the present invention technological scheme.
