Gap between lid 42 and water pipe 3.
The water tank that the water tank can be used as water heater uses.Water tank is divided into shell 2, adiabator layer, liner 1 three mainly
Part.The outer surface of shell 2 is contacted with external environment, and 1 inner surface of liner is contacted with water, and 2 inner surface of shell and 1 appearance of liner
It is partially filled with adiabator layer between face, the effect of this part mainly provides heat preservation for the water in water tank, makes in water tank
Hot water can keep temperature to stablize for a long time.Since adiabator layer mostly uses foamed material to reach heat insulation effect, and foaming material
The problems such as material has stronger water imbibition, will cause heat insulation effect decline and liner corrosion after adiabator layer water suction.It is logical
Setting connection seal assembly is crossed, shell 2 and liner 1 can be sealed, between preventing water from protruding between liner 1 and shell 2
Gap effectively completely cuts off contact channel of the adiabator layer with external environment.
According to another aspect of the present invention, a kind of water heater is provided, water heater includes above-mentioned water tank.
The tapping of the liner 1 of the water tank is welded with overhanging projecting tube 11, and the periphery of the projecting tube 11 is provided with outer spiral shell
Line, to be threadedly coupled with water pipe flange 41, to steadily fix water pipe flange 41 and water pipe 3.It is provided in projecting tube 11
First limiting stand terrace, cooperates with the second limiting stand terrace of 3 periphery of water pipe, carries out backstop limit to water pipe 3.First limit
It is provided with the first gasket between step surface and the second limiting stand terrace, to be sealed.Second limiting stand of water pipe flange 41
It is provided with pockets on terrace, the second gasket 5 is equipped in the pockets, the second gasket can be right after being installed in place
Water pipe 3 and the fit clearance of the projecting tube 11 of liner 1 are effectively sealed, and radiator leak is prevented.
Gland 42 and shell 2 carry out assembly cooperation, and the 4th limiting stand terrace that gland 42 and shell 2 cooperate is equipped with ditch
Slot, groove is interior to be equipped with third gasket.Gland 42 is extended to the part outside shell 2 equipped with internal screw thread.Locking head 43 passes through screw thread
It is connect with gland 42.Locking head 43 is equipped with external screw thread, can be cooperated with the internal screw thread of gland 42.Locking head 42 protrudes into gland 42
It is provided with the 4th gasket 7 between the 5th limiting stand terrace on interior 41 outer wall of end face and water pipe flange, when locking head is installed
After in place, the 5th gasket 7 reaches sealing effect by compression, and has a reaction force towards 43 direction of locking head, so that gland
42 and locking head 43 as a whole towards pressure is applied on 2 inner wall of shell, so that the 4th gasket 6 of compression, reaches sealing effect
Fruit.It may finally achieve the purpose that water tank heat preserving material layer and external environment are completely isolated.
It water tank according to the present invention and is had the following technical effect that with its water heater
Increase connection seal assembly on the shell, cooperate it with water pipe, then compresses on the shell, connection sealing
It is provided with sealing structure on component and shell contact surface, sealing effect can be reached by the sealing structure of setting after being installed in place
Fruit, to cut off the channel that the water in environment enters foaming thermal-insulating layer.Existing cisten mechanism shell is solved with this to be located at
Resigning via hole is needed at inlet and outlet pipes, this via hole will cause external environment and intermediate insulating layer perforation connects, when air is wet
Spend larger the problem of being that steam will enter insulating layer, insulating layer is made to absorb water.Prevent outside water in this way and enters guarantor
The problem of decline of thermal insulation property caused by warm layer and liner corrode reduces after cost to improve the quality of product.
By increasing the structure type of locking head and the 4th gasket, make tank shell be located at mouth of a river position via hole and
Water pipe forms sealing, so that insulating foam layer is completely isolated with external environment.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, made any to repair
Change, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
