Abstract
The utility model discloses the sealing device of the end of the liner of electric water heater and is suitable for the opening that is with neck and which is arranged at one end of liner and the sealing of bowl shaped shrouding disc that connects supporting electric heating pipe. The utility model is characterized in that: a fixed groove ring whose cross section takes the shape of a downward folded edge with variable length is welded on the circumference of the neck. The groove ring is slightly lower than the neck and attaches close to the place of the neck. The folded edge of the upper part of the neck presses on the upper plane of the groove ring. A sealing ring is positioned between the folded edge of the neck and the shrouding disc of the port. A press groove ring with upward folded edge is arranged on the shrouding disc of the port. A bolt connects the fixed groove ring, the press groove ring and the port shrouding disc to press the sealing ring. The utility model has the advantages of simple structure, excellent sealability and convenient installment.
Description
Technical field
This use is novel to relate to a kind of electric heater courage body port sealing device structure.Belong to electric heater architecture advances technology.
Background technology
The courage body port of electric heater is owing to require to place electric heating tube, therefore its diameter is relatively large, and can not adopt seal with screwed joint, adopt for this reason that simple in structure, sealing is tight, the port sealing device structure of easy accessibility is one of key technology of connection-related electricity use water heater quality quality.
Summary of the invention
The purpose of this utility model is to provide a kind of electric heater courage body port sealing device structure, and the sealing apparatus structure is simple, good airproof performance, easy accessibility.
The utility model is realized by following proposal, be shaped at courage body one end on the opening of band neck, the cancave bowl shaped port shrouding disc that connects the supporting electrothermal tube, their sealing device structure feature is, the fixedly grooved ring that is not isometric following flange at cross section of the periphery of mouth neck welding, this grooved ring is lower than mouthful neck slightly and mouthful neck that reclines is placed, plane pressing on mouth neck upper end flange and the grooved ring, and between mouth neck flange and port shrouding disc, place sealing ring, the grooved ring that compresses of upper overturning is set on the port shrouding disc, screw is worn and is connected fixedly grooved ring and compress grooved ring and port shrouding disc, compresses sealing ring and seals.
Above-mentioned fixedly grooved ring is offered the screw hole of side mouth, and screw is the rectangle square toes.
The utility model is simple in structure, good airproof performance, easy accessibility.
Description of drawings
Fig. 1 is the utility model structural representation.
1 is that courage body shell, 2 is that fixedly grooved ring, 3 is that port shrouding disc, 4 is that sealing ring, 6 is that electric heating tube, 7 is a screw for compressing grooved ring, 5 among the figure.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further specified.After electric heater courage body 1 is made well, fixedly grooved ring 2 with a length of side limit and one side minor face, its long limit 1 mouthful of neck of courage body that reclines, carry out the bottom welding, and guarantee that the grooved ring height is lower than a mouthful neck height slightly, like this when being subjected to thrust, mouthful neck nature outward flanging also is pressed together on fixedly on the grooved ring, compress grooved ring 4 placing sealing ring 5 on the mouth neck crimp and between the port shrouding disc and on port shrouding disc 3, place then, and with screw 7 with their connections, compress, so just realized the sealing of courage body port.
