Abstract
The utility model relates to a connecting joint structure for an inner water pipe of a water heater. A thinner pipe joint is in bayonet joint with a thicker pipe joint, and is inserted into the thicker pipe joint; the surface of the outer diameter of the insertion end of the thinner pipe joint is provided with an annular bulge, wherein, one side adjacent to the pipe head end of which is tightly hooped with an O-shaped sealing ring; the connection position of the pipe heads having unequal diameters on both ends is fixed through a sheet-shaped limit clamp device, wherein, the center of which is provided with an open semicircular clamp hole which is clamped on the outer side of the annular bulge on the surface of the outer diameter of the insertion end of the thinner pipe joint; the edge of the sheet-shaped limit clamp device is clamped on the outer surface of the thicker pipe joint. After the structure is used, the installation becomes convenient, and the corrosion phenomenon is reduced.
Description
The utility model belongs to water heater accessory field, particularly relates to a kind of jointing structure of water heater inner conduit.
The inner water route tubing coupling of water heater at present, the general pipe collar that adopts, spigot, the first-class screwed accessory of loose joint connects screwed two tube heads in end, the shape of tube head external diameter can be circular, also can be the bigger valve body of volume or other special-shaped tube head.This structure that connects with the screw thread tube head, the cost of production height requires high to material, need rotate pipe fitting and link or joint during installation, installment work is loaded down with trivial details, inefficiency, after long-time the use, because of screw threads for fastening, corrosion sometimes, replacing, inconvenient maintenance, some plastic fittings, thin-wall metal pipe is with being threaded, reduced the intensity of tube head, poor reliability, being threaded, sealing is poor sometimes, need to twine raw meal belt, it is not easy to construct.
The purpose of this utility model provides a kind of jointing structure that need not the water heater inner conduit of screw thread, and installment work is simplified, and saves cost, convenient maintenance and replacement, good airproof performance, wide adaptability.
The utility model has adopted following technological scheme to achieve these goals,
The jointing structure of conduit pipe comprises the not isometrical tube head in two ends, seal ring and fastening piece in a kind of water heater, it is characterized in that:
In the not isometrical tube head in two ends is bayonet joint than the tubule head and than the extra heavy pipe head, insert than in the extra heavy pipe head than the tubule head, insertion end than the tubule head has an annular projection on external diameter surface, annular projection tube head end one side lock ring has O-ring seals, not isometrical tube head joint, two ends is by fixing as the spacing jig of the sheet of fastening piece, there is an open semicircle hole clipping in the central authorities of the spacing jig of sheet, be stuck in than the annular projection of the tubule head insertion end external diameter surface outside, the edge card of the spacing jig of sheet is than extra heavy pipe head outside.
Describedly can be circle than extra heavy pipe head external diameter, there is flange the end, and the spacing jig of sheet both sides are rolled, and is stuck in than on the outer flange of extra heavy pipe head.
Described is abnormity than extra heavy pipe head external diameter, and there is draw-in groove the end, and the edge of spacing jig inserts in the draw-in groove stuck.
Turn up one end of the spacing jig of described sheet, forms handle.
The semicircle hole clipping circumferential distribution of the spacing jig of described sheet has the adjusting gap, and hole clipping is along circumferential direction of insertion perk.
Top layer plating one deck anticorrosive coat of the spacing jig of described sheet.
There is a pair of intermediate plate in the hole clipping outside of the spacing jig of described sheet, is clipped in caliber outer surface both sides, the tubule annular projection outside.
The utility model has the advantages that: after adopting above scheme, only need during installation O-ring seals tightly is enclosed within on the tubule head, and together insert the extra heavy pipe head, plug the sealing jig again.Operation is simple, and working efficiency improves greatly, during maintain and replace, also no longer have corrosion phenomena, and protruding structure and hole clipping are stuck, have O-ring seals to make for the high-elastic waterproof material again, circular cross-section makes to be inserted conveniently, and sealing effect is good again, can bear 15 kilograms hydraulic pressure.Extra heavy pipe head outer surface can be used collar flange, also can make draw-in groove, makes this kind jointing structure Applicable scope very wide.Jig is made with hard metal, and hole clipping forms pre-fastening structure along the perk of circumferential tubule headring shape protrusion direction, has guaranteed the fastness of intensity and joint structure.The semicircle hole clipping circumferential distribution of the spacing jig of sheet has the adjusting gap, and the hole clipping of spacing jig can be regulated within the specific limits according to the size of tubule head external diameter, makes the using scope of jig bigger, also blocks tightlyer between jig hole clipping and the tubule.
Below in conjunction with accompanying drawing this water heater conduit jointing structure is described in further detail.
Fig. 1 is the schematic representation of tubule head and circular extra heavy pipe head jointing structure:
Fig. 2 is the schematic representation of the spacing jig on tubule head and the circular extra heavy pipe head jointing;
Fig. 3 is the plan view that is limited to jig shown in Figure 2;
Fig. 4 is the schematic representation of tubule head and special-shaped extra heavy pipe head jointing structure:
Fig. 5 is the schematic representation of the spacing jig on tubule head and the special-shaped extra heavy pipe head jointing:
First kind of scheme of the jointing structure of water heater inner conduit as shown in Figure 1 comprises the extra heavy pipe head 12, O-ring seals 8 of tubule head 11, external diameter circle and as the spacing jig 1 of the sheet of fastening piece.The O-ring seals section is circular, and 2 times of circular diameter are slightly larger than or equal the poor of extra heavy pipe head and tubule head internal diameter.
Than tubule head 11 be bayonet joint than extra heavy pipe head 12, insert than in the extra heavy pipe head 12 than tubule head 11, than the insertion end of tubule head one annular projection 10 is arranged on external diameter surface, annular projection 10 forms for pushing in casting process.Annular projection tube head end one side lock ring has O-ring seals 8, two tube head joints are by fixing as the spacing jig of the sheet of fastening piece, there is an open semicircle hole clipping 5 in the central authorities of the spacing jig of sheet, are stuck in annular projection 10 outsides than tubule head insertion end external diameter surface.The extra heavy pipe cephalic par has a collar flange 9, and the edge 2 of the spacing jig of sheet is stuck in the flange than the extra heavy pipe cephalic par.The rearward end of the spacing jig of described sheet is turned up, and forms handle 3.The semicircle hole clipping circumferential distribution of the spacing jig of sheet has the gap 6 of adjusting, and hole clipping forms pre-fastening structure along the perk of circumferential tubule headring shape protrusion direction.Top layer plating one deck anticorrosive coat of the spacing jig of sheet.In order to allow jig and two more firm blocking of tube head, there is a pair of intermediate plate 4 in the hole clipping outside of the spacing jig of sheet, is clipped in the tube-surface both sides of tubule headring shape projection back.
The another kind of scheme of the jointing structure of water heater inner conduit as shown in Figure 4, the structure of tubule head 11 and O-ring seals is identical with first kind of scheme, and the external diameter of extra heavy pipe head is a profiled plastic valve body 14.There are two draw-in grooves 13 end of valve body, as the spacing jig 7 of the sheet of fastening piece, with the difference of spacing jig 1 is, two edges 2 of spacing jig 7 are not rolled, but straight, and two edges 2 insert in the draw-in groove, regulating gap is a bigger adjusting gap 6, and other is identical with first kind of scheme.
