Abstract
The invention relates to a copper coil pipe connector applied to a heat exchange water tank. The copper coil pipe connector comprises a connecting pipe sleeve, wherein an annular lug boss with an L-shaped section is formed on the upper end surface of the connecting pipe sleeve; a joint of a copper coil pipe is inserted into the connecting pipe sleeve; an upper sealing isolation pad and a lower sealing isolation pad are respectively inserted into the upper end and the lower end of the joint; the upper sealing isolation pad props against the bottom surface of the annular lug boss, and the lower sealing isolation pad props against a locking threaded sleeve; a plurality of through holes are formed in the outer side wall of the connecting pipe sleeve, and cap-shaped sealing spacers are inserted into the through holes of the connecting pipe sleeve; bolts penetrate through the sealing spacers and are then connected to the joint by threads. The invention provides the joint which is connected to a barrel body of the heat exchange water tank and is simultaneously connected with the copper coil pipe inside the heat exchange water tank; the barrel body of the heat exchange water tank is isolated from the joint connected with the copper coil pipe, and thus the electrochemical corrosion is reduced and the service life of the heat exchange water tank is prolonged.
Description
Technical field:
The present invention relates to the technical field of water heater, more specifically to a kind of bronze pan tube connecting head being applied to heat exchange water tank.
Background technique:
Current heat exchange water tank generally has cylindrical shell and is placed on the heat exchanger formation of cylindrical shell, and the cylindrical shell of its heat exchange water tank carries out enamel or directly adopts stainless steel welded forming after generally adopting iron plate to weld, the red copper material that its most heat exchanger generally adopts heat conduction efficiency higher is simultaneously made.So under many circumstances, the cylindrical shell making heat exchange water tank is not identical with the metallic material of heat exchanger, when two kinds of metallic material directly contact mutually, the metal active difference of different materials matter can produce potential difference, and the Media Contents that the metal of these two kinds of unlike materials is placed on heat exchange water tank easily produces electrochemical reaction, so-called electrochemical corrosion will be there is for the material stronger relative to activity, and the heat exchanger in existing heat exchange water tank generally adopts bronze pan tube, thus need to be isolated by insulating part between the joint of connection bronze pan tube and the cylindrical shell of heat exchange water tank.
Summary of the invention:
Object of the present invention is exactly the deficiency for prior art, and provides a kind of bronze pan tube connecting head being applied to heat exchange water tank, and it can be avoided connecting between the joint of heat exchange water tank cylindrical shell and the joint connecting bronze pan tube and directly contact, thus extends working life.
Technology solution of the present invention is as follows:
A kind of bronze pan tube connecting head being applied to heat exchange water tank, comprise connection pipe box, the upper-end surface connecting pipe box forms the L-shaped annular boss in cross section, connect the joint that pipe box interpolation is connected to bronze pan tube, the upper and lower end of joint is inserted with seal isolation pad and lower seal isolation pad respectively, upper seal isolation pad is pressed against on the bottom surface of annular boss, lower seal isolation pad is pressed against locking screw and puts, the outer side wall of described connection pipe box forms some through holes, the through hole connecting pipe box is plugged with the sealing spacer of hat shape, and bolt is screwed onto on joint through sealing spacer.
Described bolt is at least provided with individual, and bolt does not contact with joint madial wall, and described bolt is distributed in the upper and lower end of joint.
The outer side wall of described connecting tube collar-shaped boss forms screw thread, annular boss is bolted with female adapter.
Described joint is cylindrical, and joint outer sidewall diameter is less than and connects pipe box inner sidewall diameter, and the length of joint is not more than the length connecting pipe box.
Beneficial effect of the present invention is:
Which propose and to be a kind ofly connected on heat exchange water tank cylindrical shell and the joint of heat exchange water tank internal copper coil pipe can be connected simultaneously, its heat exchanging water tank cylindrical shell is isolated with the joint being connected bronze pan tube, thus reduce the generation of electrochemical corrosion, extend the working life of heat exchange water tank.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention;
Fig. 2 is sectional structure schematic diagram of the present invention.
In figure: 1, connect pipe box; 2, joint; 3, upper seal isolation pad; 4, lower seal isolation pad; 5, swivel nut is locked; 6, spacer is sealed; 7, bolt; 8, female adapter; 11, annular boss; 12, through hole; .
Embodiment:
Embodiment: see Fig. 1, shown in 2, a kind of bronze pan tube connecting head being applied to heat exchange water tank, comprise and connect pipe box 1, the upper-end surface connecting pipe box 1 forms the L-shaped annular boss in cross section 11, connect the joint 2 being plugged with bronze pan tube in pipe box 1, the upper and lower end of joint 2 is inserted with seal isolation pad 3 and lower seal isolation pad 4 respectively, upper seal isolation pad 3 is pressed against on the bottom surface of annular boss 11, lower seal isolation pad 4 is pressed against on locking swivel nut 5, the outer side wall of described connection pipe box 1 forms some through holes 12, the through hole 12 connecting pipe box 1 is plugged with the sealing spacer 6 of hat shape, bolt 7 is screwed onto on joint 2 through sealing spacer 6.
Described bolt 7 is at least provided with 2, and bolt 7 does not contact with joint 2 madial wall, and described bolt 7 is distributed in the upper and lower end of joint 2.
The outer side wall of described connection pipe box 1 annular boss 11 forms screw thread, annular boss 11 is bolted with female adapter 8.
Described joint 2 is cylindrical, and joint 2 outer sidewall diameter is less than and connects pipe box 1 inner sidewall diameter, and the length of joint 2 is not more than the length connecting pipe box 1.
Working principle: Placement of the present invention is: first bronze pan tube is screwed onto joint 2 through the annular boss 11 connecting pipe box 1, go to connect heat exchange water tank cylindrical shell with female adapter 8 again, and joint 2 is connected pipe box 1 while namely serving seal action with lower seal isolation pad 4 by upper seal isolation pad 3 isolates, also have and can move axially by limiting joint 2, and use bolt 7 can limiting joint 2 radial rotating through connecting that pipe box 1 is screwed onto on joint 2, and make bolt 7 by sealing spacer 6 and be connected pipe box 1 and isolate.
