Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and to simplify the description, but do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the present invention.

Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless specifically limited otherwise.

Referring to fig. 1-5, the present invention provides a technical solution: the utility model provides a radiator anticorrosion device based on sacrificial anode protection principle, prevent corrosion of block 2 including heating pipe interface 1 and alloy, alloy anticorrosion block 2 is crescent and its inboard one deck is regional 21 for active metal, the regional 21 outside of active metal is regional 22 for relative inert metal, active metal region 21 sets up the metal block of different liveliness with regional 22 for relative inert metal, alloy mounting groove 23 has been seted up on the regional 22 for relative inert metal, alloy mounting groove 23 matches and corresponds the installation with the protruding 11 cooperations of alloy installation on the 1 inner wall of heating pipe interface, the protruding 11 bottoms of alloy installation just open on 1 inner wall of heating pipe interface has round welding groove 12.

Furthermore, 20 alloy mounting bulges 11 surround the inner wall of the heating water pipe connector 1;

specifically, the alloy anti-corrosion block 2 is one block.

The active metal region 21 is a magnesium metal mass, in which case the relatively inert metal region 22 is a zinc metal mass or an aluminum metal mass.

The active metal region 21 is a zinc metal mass, while the relatively inert metal region 22 is an aluminum metal mass.

The relatively inert metal region 22 may be divided into two layers of metal, zinc and aluminium alloy from the outside to the inside respectively, in which case the active metal region 21 is a magnesium metal block.

It is worth to be noted that the protection principle of the sacrificial anode is essentially that oxygen and electrons of the protected metal are consumed by more active metal, so that in principle, the metal activity of the alloy protection block only needs to be more active than iron; at the same time, in order for the consumption of the alloy anti-corrosion block 2 to be gradual and regular, it is necessary to order the active metal area 21 and the relatively inert metal area 22. Therefore, the oxide generated by the reaction cannot be mixed in other metal areas to prevent the reaction from further occurring, and the relatively active metal in the alloy anti-corrosion block 2 can not preferentially react, so that the whole metal block is separated and broken.

The actual solder mound height of the solder bath 12 needs to be higher than the thickness of the alloy anti-corrosion block 2. So that the lower end of the alloy anti-corrosion block can be firmly sealed by the solder at any time.

The active metal region 21 is one or an alloy of magnesium, zinc or aluminum metal, while the relatively inert metal region 22 is one or an alloy of indium, cadmium and iron.

Specifically, the alloy anti-corrosion block 2 can be simplified to a layer of reactive metal, i.e., the active metal region 21; and now functions as a mounting and securing function with respect to the inert metal area 22.

The shape of the alloy anti-corrosion block 2 is a half-throw shape, and the whole thickness of the alloy anti-corrosion block 2 does not obstruct the normal flux of the water flow of the water pipe connector 1. The half-throw shape is another optional shape of the alloy anti-corrosion block 2, as shown in fig. 5, the whole volume of the half-throw shape is larger than that of a crescent shape, the service life is generally longer, but the contact surface of the half-throw shape is smaller, the reaction rate is lower, the half-throw shape is suitable for the conditions of long working life and low corrosion rate prediction, and the half-section shape can be installed by a plurality of blocks and can be freely combined. But the design thickness can not influence the normal flow of the water flow

The utility model discloses a work flow: the heating water pipe interface 1 and the alloy anti-corrosion block 2 are well installed by correspondingly matching the alloy installation groove 23 on the alloy anti-corrosion block 2 with the alloy installation bulge 11 on the heating water pipe interface 1, and then the welding groove 12 is filled with welding flux and is welded and fixed;

when corrosion occurs, the reaction starts from the active metal area 21, closest to water and air, of the alloy anti-corrosion block 2, the structure and the properties of the relative inert metal area 22 are not changed, then the reaction starts to be consumed only by the relative inert metal area 22 until the active metal area 21 is completely consumed, but the relative inert metal area 22 is clamped between the alloy mounting bulges 11 on one hand, and the welding groove 12 at the bottom is firmly fixed on the other hand, so that the work of the alloy anti-corrosion block is still not influenced, and the protective performance of the alloy anti-corrosion block 2 is completely exerted in the whole process.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the description in the above embodiments and the description is only preferred examples of the present invention, and is not intended to limit the present invention, and that the present invention can have various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications all fall into the scope of the claimed invention.
