Description
Technical field
The utility model relates to the parts in Water electric heater, specifically refers to the temperature-measuring casing for exclusion of water and temperature element in Water electric heater.
Background technology
Temperature-measuring casing is the critical elements for exclusion of water and temperature element in Water electric heater, and its function is that water and temperature element definitely completely cut off by requirement, prevents in seepage inlet pipe, therefore requires very high to product quality.
Existing temperature-measuring casing carries out argon welding sealing in flattening place after being all directly flattened by pipe afterbody when making, because argon welding temperature is high, certain oxidative phenomena is produced to metal material, pipe is caused to get rusty easily, there is risk of leaking, there is welding non-uniform phenomenon in argon arc welding technique itself simultaneously, has pin hole during welding, there is risk of leaking.
Utility model content
The purpose of this utility model is to provide the temperature-measuring casing for exclusion of water and temperature element in Water electric heater, and this temperature-measuring casing has good sealing property, can drop to minimum by the risk of leaking of temperature-measuring casing.
This purpose of the present utility model realizes by the following technical solutions: for the temperature-measuring casing of exclusion of water and temperature element in Water electric heater, it is characterized in that: described temperature-measuring casing afterbody is flatten the flattening section formed, temperature-measuring casing tail end is flatten the hydraucone formed, described hydraucone has pipe external seal at the position contacted with described flattening section and welds bar, described pipe external seal welding bar melts in ammonia stove after being painted into solder paste, welding is formed, solder paste melts at ammonia stove simultaneously, in welding process, the space of flattening section is filled in infiltration, and infiltrate in temperature-measuring casing pipe, wherein, fill the solder paste flattening section space and form flattening section welding zone, the solder paste infiltrated in temperature-measuring casing pipe forms sealing welding in pipe, described pipe external seal welding bar, flatten sealing welding three in section welding zone and pipe and jointly form the sealing weldment of temperature-measuring casing, ensure that the sealing property of temperature-measuring casing.
In the utility model, described solder paste is money base soldering paste or copper base soldering paste or Ni-based soldering paste or aluminium base soldering paste or tinbase soldering paste.
Compared with prior art, pipe afterbody place flattens by the utility model temperature-measuring casing, caudal end is caused to become hydraucone shape, be painted into solder paste at hydraucone place and cross ammonia stove and carry out welded seal process, solder paste can be dissolved by ammonia stove and fully fill up the space of temperature tube afterbody flattening, reach welded seal effect, weld the pipe external seal welding bar of formation simultaneously, flatten seal weld in section welding zone and pipe and bring temperature-measuring casing and provide triple seal, ensure that the sealing property of temperature-measuring casing

Embodiment
As Fig. 1, for the temperature-measuring casing 1 of exclusion of water and temperature element in Water electric heater shown in Fig. 2, this temperature-measuring casing afterbody is flatten the flattening section 11 formed, temperature-measuring casing tail end is flatten the hydraucone 12 formed, hydraucone 12 has pipe external seal at the position contacted with flattening section 11 and welds bar 23, pipe external seal welding bar 23 melts in ammonia stove after being painted into solder paste, welding is formed, solder paste melts at ammonia stove simultaneously, in welding process, the space of flattening section is filled in infiltration, and infiltrate in temperature-measuring casing pipe, wherein, fill the solder paste flattening section space and form flattening section welding zone 22, the solder paste infiltrated in temperature-measuring casing pipe forms sealing welding 21 in pipe, pipe external seal welding bar 23, flatten sealing welding 21 three in section welding zone 22 and pipe and jointly form the sealing weldment of temperature-measuring casing 1, triple seal is provided to temperature-measuring casing 1, ensure that the sealing property of temperature-measuring casing 1.
In the present embodiment, solder paste adopts Ni-based soldering paste, also can adopt money base soldering paste or copper base soldering paste or Ni-based soldering paste or the welding material such as aluminium base soldering paste or tinbase soldering paste.
The temperature-measuring casing 1 of the present embodiment, there is in pipe sealing welding 21 in pipe and carry out sealed crush section tool Packed flattening section welding zone 22, manage outer hydraucone place to have pipe external seal welding bar 23 and seal, triple seal can the risk of leaking of just temperature-measuring casing drop to minimum.
Above-described embodiment of the present utility model is not the restriction to the utility model protection domain; embodiment of the present utility model is not limited thereto; all this kind is according to foregoing of the present utility model; according to ordinary technical knowledge and the customary means of this area; do not departing under the utility model above-mentioned basic fundamental thought prerequisite; to the amendment of other various ways that the utility model said structure is made, replacement or change, all should drop within protection domain of the present utility model.
