Abstract
The utility model discloses a heat pump water heater with built-in coil pipes comprising a casing, a heat exchange coil pipe disposed inside the casing, the opening of the casing being provided with a flange, [the] heat exchange coil pipe penetrating from the flange, wherein a connecting piece is arranged between the heat exchange coil pipes and the flange, the connecting piece sleeving on the external of the heat exchange coil pipes, the upper end of the connecting piece being provided with an upper gland nut, the lower end of the connecting piece being provided with a lower gland nut; wherein the upper gland nut and the connecting piece is provided with a first sealing ring between the two, the lower gland nut and the connecting piece being provided with a second sealing ring between the two, the lower end of the flange and the connecting piece being provided with a third sealing ring between the two, above the flange being provided with a locking nut which sleeves on the connecting piece. The adoption of rubber or nylon as materials for the sealing rings and the formation of sealing by screwing and compressing and deforming of the gland nuts and the connecting piece of the utility model guarantees no leakage of water from the tank. In the whole connection, no places need welding, which guarantees a long time service.
Description
Technical field
The utility model relates to a kind of household electrical appliance, relates in particular to the built-in Teat pump boiler of a kind of coil pipe.
Background technology
Teat pump boiler has become the household electrical appliance of each family's indispensability, the price material benefit, easy for installation, but the coil pipe of Teat pump boiler generally all is to be welded on the ring flange of inner water tank mostly, and Teat pump boiler is through long-term use, and the welding position soaks in water for a long time, can corrode so that bore a hole and leak, if maintenance needs very high expense, and the welding position poor quality, damage easily.
Summary of the invention
The utility model will solve the shortcoming of above-mentioned prior art, and a kind of unjointed Teat pump boiler is provided, and therefore can guarantee long-term the use.
The utility model solves the technical scheme that its technical problem adopts: the water-heater water tank that this coil pipe is built-in, comprise casing, be provided with heat exchange coil in the casing, the opening part of casing is provided with ring flange, heat exchange coil passes in ring flange, be provided with connector between this heat exchange coil and the ring flange, this connector is enclosed within the outside of heat exchange coil, its upper end is provided with the upper press cover nut, the lower end is provided with the lower cover nut, is respectively equipped with first sealing ring, second sealing ring between upper press cover nut, lower cover nut and the connector; Be provided with the 3rd sealing ring between the lower end of ring flange and the connector, the top of ring flange is provided with locking nut, and this locking nut is socketed on the connector.This structure adopts sealing rings such as rubber or nylon, compresses distortion by screwing of gland nut and connector, forms sealing, guarantees that the water in the water tank can not leak, and in the whole series connect, does not need the place of welding, so can guarantee use for a long time.
The effect that the utility model is useful is: the utility model structure adopts sealing rings such as rubber or nylon, compress distortion by screwing of gland nut and connector, form sealing, guarantee that the water in the water tank can not leak, in the whole series connect, do not need the place of welding, so can guarantee long-term the use.
