Abstract
The utility model relates to a heat exchanger joint, which comprises a plug and a metal bar made of active metal material, wherein one end of the plug is an end head, the other end of the plug is provided with connection threads, one end of the metal bar is an extending end, the other end of the metal bar is a connecting end, a corresponding mounting port is arranged in the plug, the connecting end of the metal bar is connected with the plug via a mounting hole of the plug, the connecting end of the metal bar is provided with external threads, internal threads corresponding to the external threads are arranged in the mounting port of the plug, and the end head of the plug is a circular or hexagonal head. The utility model is additionally provided with metal material capable of being used as an anode at one end of the plug by a sacrificial anode protection method in the principle of electrochemical corrosion protection, thereby improving the corrosion resistance of the whole joint and the seal between a water outlet and a water tank of a heat exchanger pipeline so as to prolong the overall service life of the heat exchanger.
Description
Technical field
The utility model provides a kind of heat exchanger connection device, especially a kind of heat exchanger joint.
Background technology
The normal welding manner that adopts seals between the pipeline of past heat exchanger and the water tank; and because the heat exchanger domestic demand is often carried out cold and hot medium alternately; therefore usually can crackle appear because of weld seam; and cause leaking; and in case it is very difficult spillage risk to occur; take place for fear of this phenomenon; between pipe water outlet and water tank, adopt plug to be connected now but because cold and hot medium has corrosivity; usually can corrode plug; therefore plug needs often to change, thereby has influenced the service life of joint.
The utility model content
The utility model is by can be used as the metal material of anode in plug one end increase, thereby plug is shielded, and improves the life-span of joint, improves the sealing between heat exchanger tube delivery port and the water tank, solves the problem that plug corrodes easily.
Provide a kind of heat exchanger joint for reaching this purpose the utility model, comprise plug and the metal bar of making by the reactive metal material, described plug one end is the termination, the plug other end is provided with connecting thread, described metal bar one end is an external part, the other end is a link, is provided with corresponding installing port in the described plug, and the link of described metal bar is connected with plug by the installing hole of plug.
Link as the described metal bar of further improvement of the utility model is provided with external screw thread, be provided with in the installing port of described plug and the corresponding internal thread of the external screw thread of metal bar link, adopt the mode that is threaded to be connected for the ease of connecting between the utility model plug and the metal bar, also can adopt other removably to be connected between the utility model plug and the metal bar.
Termination as the described plug of further improvement of the utility model is circle or hexagon, and the termination of the utility model plug promptly can be circle and also can be hexagon, and producer can select as required.
The utility model utilizes the sacrificial protection in the electrochemical anti-corrosive erosion principle to can be used as the metal material of anode in plug one end increase; thereby improved the corrosion resistance of whole joint; improve the sealing between heat exchanger tube delivery port and the water tank, made the whole service life of heat exchanger be improved.

The specific embodiment
Below in conjunction with drawings and Examples utility model is described in detail:
The utility model provides a kind of heat exchanger joint as shown in Figure 1; comprise plug 1 and the metal bar of making by the reactive metal material 2; a described plug end as shown in Figure 2 is termination 1-1; plug 1 other end is provided with connecting thread; described metal bar 2 end as shown in Figure 3 is external part 2-1; the other end is link 2-2; be provided with corresponding installing port in the described plug 1; the link 2-2 of described metal bar 2 is connected with plug 1 by the installing hole of plug 1; thereby by can be used as the metal material of anode in plug 1 one end increases; thereby plug 1 is shielded; improve the life-span of joint; improve the sealing between heat exchanger tube delivery port and the water tank, solve the problem that corrosion takes place plug 1 easily.
The link 2-2 of metal bar 2 of the present utility model is provided with external screw thread, be provided with the corresponding internal thread of external screw thread in the installing port of described plug 2 with metal bar 2 link 2-2, be connected for the ease of connecting the mode that employing is threaded between the utility model plug 1 and the metal bar 2, also can adopt other removably to be connected between the utility model plug 1 and the metal bar 2.
The termination 1-1 of plug 1 described in the utility model is circle or hexagon, and the termination 1-1 of the utility model plug 1 promptly can be circle and also can be hexagon, and producer can select as required.
The utility model utilizes the sacrificial protection in the electrochemical anti-corrosive erosion principle to can be used as the metal material of anode in plug one end increase; thereby improved the corrosion resistance of whole joint; improve the sealing between heat exchanger tube delivery port and the water tank, made the whole service life of heat exchanger be improved.
The above; it only is preferred embodiment of the present utility model; be not to be the restriction of the utility model being made any other form, and, still belong to the utility model scope required for protection according to any modification or equivalent variations that technical spirit of the present utility model is done.
