Technical field
The present invention relates to a kind of convenient plumb joints of inexpensive heat exchanger.
Background technology
Between existing heat exchanger and rear end copper pipe, stainless joint end is set using onboard welding, then again should
End is fixed with the mode that copper pipe directly welds, because to bear at least pressure of 22KG in weld so as to weld
Quality requirement is very strict.But stainless steel and copper are two kinds of different materials, the fusing point of the two is different, the fusing point of stainless steel
At 1300 DEG C, the two is heated separately to adaptive temperature and welded again by the fusing point of copper at 900 DEG C so that the condition control to welding
Make extremely difficult, impurity can also influence welding effect, and the requirement of carefulness and experience to welder is all very high, even and good
Welder, can only also ensure 90% or so success rate, therefore existing method not only high labor cost, and yield is low.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of convenient plumb joint of readily replaceable inexpensive heat exchanger.
The present invention is achieved through the following technical solutions：
The convenient plumb joint of inexpensive heat exchanger, is fixed at comprising its bottom at the import or export on heat exchanger end plate
The copper pipe joint that bottom buckle and its top are connected with copper pipe, the top of supply line of the bottom buckle are equipped at least a pair of to perforating, the copper
It is sealed in the bottom insertion bottom buckle of pipe fitting and by O-ring and coordinated between the bottom of bottom buckle, the copper pipe joint is thin-walled
Metal tube extrusion forming, and layers of copper is included at least at the top of it, the bottom of the copper pipe joint is first annular equipped at least one
Groove, the O-ring are arranged in the first annular groove, and an at least second annular groove is additionally provided on the copper pipe joint,
Matching to punch position in bottom buckle, the copper when position of the second annular groove is in copper pipe joint bottom insertion bottom buckle
Between at the top of pipe fitting and bottom buckle by by bolt be inserted into bottom buckle top of supply line to perforate and on copper pipe joint second
It is locked in annular groove.
Preferably, the copper pipe joint is thin-wall copper pipe extrusion forming.
Preferably, the copper pipe joint is thin-wall stainless steel or iron pipe extrusion forming, and it is coated in its top position
One layer of layers of copper.
Preferably, the bottom buckle is fixed on by welding on heat exchanger end plate.
Preferably, the top of supply line of the bottom buckle is equipped with a pair to perforation.
Preferably, it is set on the copper pipe joint bottom there are two first annular groove, for setting two O-rings.
Preferably, the first annular groove is identical with second annular groove structure.
The beneficial effects of the invention are as follows：
Simple for structure ingenious, the good airproof performance of the present invention, when which is declined for a long time using rear leakproofness, when replacement, only needs
Copper pipe joint from bottom buckle is taken out, then replaces O-ring, is replaced quickly, replacement cost is extremely low, copper pipe joint
It is using thin metallic tubd extrusion forming, production process is quick, and manufacture is at low cost, and the top of copper pipe joint carries layers of copper,
It can realize the rapid welding of copper pipe joint and copper pipe, welding is very easy to, and common welder can complete well.
Description of the drawings
For ease of explanation, the present invention is described in detail by following specific embodiment and attached drawing.

Specific embodiment
As Figure 1-Figure 4, the convenient plumb joint of inexpensive heat exchanger is fixed at heat exchanger end plate comprising its bottom
On import or export at bottom buckle 1 and its copper pipe joint 2 for being connected with copper pipe of top, the top of supply line of the bottom buckle 1 be equipped with
At least for a pair to perforation 1.1, the bottom insertion bottom buckle 1 of the copper pipe joint 2 is interior and passes through O-ring between the bottom of bottom buckle 1
Sealing cooperation, the copper pipe joint 2 is thin metallic tubd extrusion forming, and is connect at least at the top of it comprising layers of copper, the copper pipe
First 2 bottom is equipped with an at least first annular groove 2.1, and the O-ring is arranged in the first annular groove 2.1, described
An at least second annular groove 2.2, position and 2 bottom of copper pipe joint of the second annular groove 2.2 are additionally provided on copper pipe joint 2
Matching to 1.1 positions of perforation in bottom buckle 1 when in insertion bottom buckle 1, pass through between the copper pipe joint 2 and the top of bottom buckle 1 by
Bolt 3 is inserted into being locked to perforation 1.1 and in the second annular groove 2.2 on copper pipe joint 2 for 1 top of supply line of bottom buckle
It is fixed.
The copper pipe joint 2 is thin-wall copper pipe extrusion forming.
Or the copper pipe joint 2 is thin-wall stainless steel or iron pipe extrusion forming, and it is coated with one layer of copper in its top position
