Abstract
An enamel double-liner jointing pipe for a water heater consists of a tank of electric water heater, a heating tube, a connecting tube, a water inlet and a water outlet. The utility model is characterized in that the tank is respectively an upper tank and a lower tank. The upper tank and the lower tank are respectively welded with the connecting tube and sheathed with a layer of protection coat after enameled by a porcelain layer. The utility model has the advantages of reasonable design, simple structure, low cost, long service life and no communication between water flow and the tank.
Description
Technical field
The utility model relates to tube connector, the two courage tube connectors of particularly a kind of water heater porcelain enamel.
Background technology
Common on the market water heater porcelain enamel courage mainly is single courage at present, its cost height, and the manufacturability poor-performing because of courage inner face end face be cannot say for sure to protect, and very easily causes the direct and courage communication of current, influences its service life etc.
Summary of the invention
The purpose of this utility model just provides a kind of reasonable in design, and is simple in structure, and cost is low, high life, current not can with the two courage tube connectors of a kind of water heater porcelain enamel that inner bag is linked up.
The purpose of this utility model is achieved in that the two courage tube connectors of a kind of water heater porcelain enamel; it comprises that water heater liner, heat-generating pipe, tube connector, water inlet and delivery port constitute; it is characterized in that described inner bag is respectively courage and following courage; last courage welds with tube connector respectively with following courage; and after enamel has enamel coating, be arranged with one deck protective sleeve.Protective sleeve is the aluminium cover.Tube connector is " L " type shape, " " type shape.The bent angle of tube connector is R.
Adopt said structure to reach and can effectively protect courage inner face end face, make the water (as A, B place) at other place can not be directly and the interior ditch of courage lead to, thereby increased its service life or the like.
Description of drawings
Fig. 1 is a structural representation of the present utility model,
Fig. 2 is a partial structurtes schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail: tube connector 1, protective sleeve 2, enamel coating 3, last courage 4, following courage 5, heat-generating pipe 6, water inlet 7, delivery port 8.Shown in Fig. 1～2; the two courage tube connectors of a kind of water heater porcelain enamel; it comprises that water heater liner, heat-generating pipe 6, tube connector 1, water inlet 7 and delivery port 8 constitute; it is characterized in that described inner bag is respectively courage 4 and following courage 5; last courage 4 welds with tube connector 1 respectively with following courage 5; and after enamel has enamel coating 3, be arranged with one deck protective sleeve 2.Protective sleeve 2 is the aluminium cover.Tube connector 1 is " L " type shape.,
The type shape.The bent angle of tube connector 1 is R.During use, tube connector 1 respectively with last courage 4, down after courage 5 welding, more respectively separately enamel enamel coating 3 is arranged, at this moment, weakness is A place, when increasing thin aluminium cover 2, aluminium cover 2 does not allow it directly contact with current the encirclement of A place.Added the courage up and down of aluminium cover 2 involutory after, integrally welded at B place because aluminium is the cathodic protection metal, add that the aluminium cover can not be directly leads to the water at A, B place with the interior ditch of courage, formation oxygen deprivation environment makes the protective effect enhancing of tube connector.Tube connector 1 is bent downwardly at the B place, and this crooked R1, R2 make the B place away from A place and circulating water under the situation that does not increase by two courage space lengths, had both reduced B place welding stress the A place is caused the burst porcelain infringement, again can the more difficult arrival of oxygenated water B place.
