The pipe expansion device provided by the invention has the advantages as follows: the pressure-resistant pipe can be conveniently mounted in a fin pipe, and the pressure-resistant pipe is completely fitted with the inner wall of the fin pipe through the expansion force of the flange to the pressure-resistant pipe, therefore, that no air exists between the pressure-resistant pipe and the fin pipe is ensured, and the pressure-resistant pipe cannot be pulled out of the fin pipe.
Description
Technical field
The present invention relates to a kind of expansion pipe device and production technology thereof.
Background technology
Finned tube is a kind of heat exchanger tube, in order to improve heat exchange efficiency, conventionally on the surface of heat exchanger tube by with fin, increase the external surface area (or internal surface area) of heat exchanger tube, thereby reach the object that improves heat exchange efficiency.
In finned tube, a pressure pipe can be set, pressure pipe can be strengthened the intensity of heat exchanger tube, can keep again good heat transfer effect, but prerequisite is very close to each other between pressure pipe and finned tube, once because there is air between pressure pipe and finned tube, can affect the heat transfer effect of finned tube, be cryogenic liquid such as what lead in pressure pipe, needs finned tube heat absorption to vaporize to cryogenic liquid, once and between finned tube and pressure pipe, there is air, can affect the effect of vaporization.
Therefore, generally by identical the interior diameter with finned tube of the diameter setting of pressure pipe, be difficult to pressure pipe to be inserted in finned tube but arrange like this, especially in the time that pressure pipe grows to tens meters, more difficult pressure pipe is inserted in finned tube completely, not only waste time and energy, and be easy to damage pressure pipe or finned tube.
Summary of the invention
The present invention is directed to prior art deficiency, a kind of expansion pipe device and production technology thereof are provided, it can conveniently install pressure pipe in finned tube, and the expansive force by flange to pressure pipe, make the pressure pipe finned tube inwall of fitting completely, ensureing does not have air between pressure pipe and finned tube, and can not be drawn out finned tube.
In order to solve the problems of the technologies described above, the present invention is solved by following technical proposals: a kind of expansion pipe device and production technology thereof, comprise pressure pipe, be provided with expand tube frock, described expand tube frock comprises connector, on described connector lateral wall, be provided with flange, described lip diameter is greater than described pressure pipe diameter, and described connector is also connected with stay cord.When use, the pressure pipe that first diameter is less than to finned tube is inserted in finned tube, then pressure pipe is passed in stay cord end, pull again stay cord, the flange of connector enters from one end of pressure pipe, in the process moving at connector, make the diameter of pressure pipe squeezed greatly, expand, and laminating finned tube inwall, until connector completes the expansion effect to pressure pipe entirety.
In technique scheme, described connector upper side offers one number service hole, on the side that described connector is connected with this upper side, offer No. two through hole, between described one number service hole and described No. two through holes, offer deep-slotted chip breaker described one number service hole and described No. two through holes are interconnected, described stay cord is connected described connector through described one number service hole with described No. two through holes.The position diameter being connected with stay cord on connector is less, makes stay cord fixing point only be subject to the power of a direction, thereby makes the good fixing effect of stay cord and connector, prevents that stay cord stay cord in pulling connector from separating with connector.
In technique scheme, on center, described connector side, offer No. three through hole, and on the center of corresponding another side, this side, offer through hole No. four, described No. three through holes and described No. four through holes are interconnected by groove, the diameter of end, described stay cord one end is greater than the diameter of described No. three through holes, the diameter of described stay cord other end end is less than the diameter of described No. three through holes, and one end that described stay cord diameter is less is connected with described connector with described No. four through holes through described No. three through holes.Stay cord straight line of living in is positioned at the center of connector, makes stay cord flange on connector in pulling connector identical to pressure pipe power everywhere, thus make that pressure pipe is inflated more even.
In technique scheme, described flange shape and described pressure pipe shape match.What make that pressure pipe expanded by flange is more even, ensures all fitting with finned tube of pressure pipe lateral wall everywhere, pressure pipe lateral wall everywhere and all very close to each other between finned tube.
The present invention also provides a kind of production technology of producing above-mentioned expansion pipe device, and its production stage is briefly described as follows: 1) first pressure pipe is inserted in finned tube; 2) then pressure pipe is passed in stay cord end; 3) pull stay cord, connector is moved, in the process moving at connector, make the diameter of pressure pipe squeezed greatly, expand.Adopt this production technology, pressure pipe can be conveniently installed in finned tube, and by flange the expansive force to pressure pipe, make the pressure pipe finned tube inwall of fitting completely, ensureing does not have air between pressure pipe and finned tube, and can not be drawn out finned tube.
The present invention compared with prior art, there is following beneficial effect: the present invention can conveniently install pressure pipe in finned tube, and the expansive force by flange to pressure pipe, make the pressure pipe finned tube inwall of fitting completely, ensureing does not have air between pressure pipe and finned tube, and can not be drawn out finned tube.The position diameter being connected with stay cord on connector is less, makes stay cord fixing point only be subject to the power of a direction, thereby makes the good fixing effect of stay cord and connector, prevents that stay cord stay cord in pulling connector from separating with connector.Stay cord straight line of living in is positioned at the center of connector, make stay cord flange on connector in pulling connector identical to pressure pipe power everywhere, thereby what make that pressure pipe is inflated is more even, ensure all fitting with finned tube of pressure pipe lateral wall everywhere, pressure pipe lateral wall everywhere and all very close to each other between finned tube.
