Abstract
The utility model provides a water heater with an integrated heating pipe, which comprises a medium-size container of an inner cavity, an integrated heating pipe, an insulating ring and a flange. The utility model is characterized in that the flange is welded at the medium-size container of the inner cavity and the middle of the flange belongs to two segments of a through hole with different inner diameters, while the through holes of the flange that are close to the external port are large in inner diameter and an inner thread is arranged on the inner wall of the through holes. The rearward of the heating pipe screw head is a circular ring bulging edge. The screw head part of the heating pipe is additionally padded with a rubber insulating ring between the steps that are formed by two segments of the through holes with different inner diameters, while a locking nut is connected with the thread in the flange through the external thread. The utility model is provided with simple and compact structure, lower cost, strict sealing, reliable insulation, convenient processing and installation, thus to effectively prevent the heating pipe from eroding.
Description
Technical field
The mounting structure that the utility model belongs to the water heater heating tube improves, and mainly solves the Insulation Problems between heating tube and the inner bag, with the protection heating tube, is a kind of water heater with direct insertion heating tube specifically.
Background technology
The mounting structure of the direct insertion heating tube of existing electric heater or solar water heater generally adopts flange plate structure, by some bolts ring flange is connected with inner bag, adds insulating washer and reaches insulation.By the resistance line heating tube is connected with inner bag again.Its complex structure, the area of ring flange is big, and insulation effect is relatively poor, the cost of manufacture height, installation effectiveness is low.
Summary of the invention
The purpose of this utility model is to provide a kind of water heater with direct insertion heating tube at the deficiency of prior art existence, and it is simple in structure, compact, and it is reliable to seal, insulate, and processing and fabricating is convenient, is convenient to installation.
The purpose of this utility model is achieved through the following technical solutions: a kind of water heater with direct insertion heating tube, comprise bucket in the inner bag, direct insertion heating tube, insulated ring, ring flange, it is characterized in that described ring flange is welded in the inner bag on the bucket, in the middle of the ring flange is the through hole of two sections different inner diameters, one section internal diameter of the outer port of ring flange through hole is bigger, internal thread is set on the through-hole wall, the spiral shell head rearward end of heating tube is an annulus convex edge, cushioning rubber-covered circle between two sections formed steps of different inner diameters in heating tube spiral shell head part and the ring flange through hole has one to tighten nut and be connected with the ring flange internal thread by its external screw thread.
At spiral shell head rear end face and tighten the ring-shaped rubber plain cushion is set between the nut.
The leading portion of described heating tube spiral shell head is a taper type, and the ring flange through hole dwindles in directly going in one section of the lining gradually, and is consistent with the taper type tapering of heating tube spiral shell head leading portion.
The ceramic connector lug of described heating tube spiral shell head rear end is connected with bucket in the inner bag by the lead of strip resistance.
The utility model compared with prior art has many advantages and good effect:
1, the leading portion of heating tube spiral shell head of the present utility model is a taper type; the ring flange through hole dwindles in directly going in one section of the lining gradually; consistent with the tapering of heating tube spiral shell head leading portion; make sealing of rubber-covered circle and good insulating between heating tube spiral shell head part and the ring flange through hole; realized the insulation of bucket in spiral shell head heating tube and the inner bag; be added with certain resistance value again, maximum reduces the galvanic current between heating tube and the inner bag, effectively protects heating tube.
2, the utility model adopt tighten increase between nut and the heating tube spiral shell head insulated ring and structure, realize the further sealing of heating tube and fix, reach better insulation effect.
3, the utility model connects spiral shell head part and inner bag by the strip resistance lead, realizes the maximum corrosiveness that reduces galvanic cell.
4, simple in structure, compact, cost of manufacture is low, easily processing.
Description of drawings
Fig. 1 is the electric heater part section structure chart that the utlity model has direct insertion heating tube.
Among the figure, 1, the rubber-covered circle; 2, resistance; 3, tighten nut; 4. rubbery flat gasket; 5, spiral shell head; 6, ceramic connector lug; 7, ring flange; 8, heating tube, 9, bucket in the inner bag.
The specific embodiment
Referring to Fig. 1, a kind of embodiment with electricity (perhaps solar energy) water heater of direct insertion heating tube.Ring flange 7 is welded in the inner bag on the bucket 9, is the through hole of two sections different inner diameters in the middle of the ring flange 7, and one section internal diameter of the outer port of ring flange 7 through holes is bigger, and internal thread is set on the through-hole wall.Heating tube spiral shell head 5 rearward end are an annulus convex edge, and cushioning rubber-covered circle 1 between two sections formed steps of different inner diameters in heating tube spiral shell head 5 parts and ring flange 7 through holes has one to tighten nut 3 and be connected with ring flange 7 internal threads by its external screw thread.At heating tube spiral shell head 5 rear end faces and tighten ring-shaped rubber plain cushion 4 is set between the nut 3.
The leading portion of heating tube spiral shell head 5 is a taper type, and ring flange 7 through holes dwindle in directly going in one section of the lining gradually, and are consistent with the taper type tapering of heating tube spiral shell head 5 leading portions.
The ceramic connector lug 6 of heating tube spiral shell head 5 rear ends is connected with bucket 9 in the inner bag by the lead of strip resistance 3.
Certainly, above-mentioned explanation is not to be to restriction of the present utility model, and the utility model also is not limited to above-mentioned giving an example; those skilled in the art; in essential scope of the present utility model, the variation of making, remodeling, interpolation or replacement all should belong to protection domain of the present utility model.
