Specific embodiment
In order that the objects, technical solutions and advantages of the present invention become more apparent, below in conjunction with drawings and Examples, right
The present invention is further elaborated.It should be appreciated that specific embodiment described herein is only in order to explain the present invention, and
It is not used in the restriction present invention.
As depicted in figs. 1 and 2, a kind of water tank 10 provided in an embodiment of the present invention, can be used as the water of different size and material
Case is used for the water heater such as electric heater, air source hot pump water heater or miscellaneous equipment.In the present invention, explain taking water heater as a example
State beneficial effects of the present invention.
As depicted in figs. 1 and 2, above-mentioned water tank 10 includes the tank box 1 with inner chamber 110, for accommodating water.Water tank
Outlet pipe 31 and oral siphon can be connected with casing 1（In figure is not shown）Deng, outlet pipe 31 and oral siphon all with tank box 1
Inner chamber 110 connects, and outlet pipe 31 and oral siphon can be respectively arranged with water intaking valve and outlet valve.
As depicted in figs. 1 and 2, tank box 1 is connected with the pressure-regulating device 2 for pressure in self-regulating water tank.
Pressure-regulating device 2 includes being connected to the elastomeric bladder 21 of tank box 1 and inflatable deformation, and elastomeric bladder 21 can be used as expansion gas
Capsule, it can be made up of elastomeric material, and in concrete application, elastomeric bladder 21 can be using elastic rubber material or other suitable material system
Become.
As depicted in figs. 1 and 2, elastomeric bladder 21 has accommodating chamber 210, and accommodating chamber 210 is connected with inner chamber 110.Elastomeric bladder 21
Accommodating chamber 210 inner space can become big under the effect of the pressure, that is, the accommodating chamber 210 of elastomeric bladder 21 has volume under stress
The ability that when change is greatly and pressure recovers, volume recovers.So, when the inner chamber 110 of tank box 1 fills water, with reference to dotted line in Fig. 3
The water surface in shown as inner chamber 110, in inner chamber 110, the mouth of pipe of the water surface and outlet pipe 31 maintains an equal level, when the inner chamber 110 of tank box 1
In water be heated and when not using water, the water expanded by heating in the inner chamber 110 of tank box 1, volume becomes big, and the water of expansion enters
Enter the accommodating chamber 210 of elastomeric bladder 21, the water surface raises, be the water surface in inner chamber 110 with reference to shown in dotted line in Fig. 4.Due to elastomeric bladder
There is air inside 21 and elastomeric bladder 21 itself is made up of elastomeric material and has shrinkage, space in elastomeric bladder 21 under the effect of the pressure
Become big, part water goes successively to the space in elastomeric bladder 21, so that water tank internal capacity becomes to offset greatly in water tank water because being subject to
Thermal expansion and the volume that produces becomes big, so that water tank 10 inside water pressure will not be excessively increased, maintain in safe range.
As depicted in figs. 1 and 2, when client's water, the current with outlet pipe 31 are discharged, and elastomeric bladder 21 is shunk and will be accommodated
Water in chamber 210 flows out from outlet pipe 31, and elastomeric bladder 21 recovers reset condition, and the interior water surface of tank box 1 and delivery port maintain an equal level,
Water tank 10 actual volume reaches initial design load, and in water tank 10, pressure returns to the level of intake pressure.When no client's water,
When water temperature in water tank 10 reduces, in water tank 10, the volume of water reduces, and elastomeric bladder 21 is shunk, and its interior water also will be returned to water tank
In, in water tank, pressure returns to the level of intake pressure.By such design, water tank internal cause water expanded by heating can be reduced and
Lead to the growth of pressure in water tank, make the hydraulic pressure in water tank in the scope of safety.Reduce the destruction to inner water tank for the hydraulic pressure, profit
In prolongation water tank service life, the security of strengthening system.And, water tank provided by the present invention, it is pacified without in-site installation
Full valve, discharge structure etc., are not affected by installation personnel technical merit, and reliability is high, further, since need not be let out by discharge opening
Water, it is to avoid the waste of water and the energy, product more energy efficient environmental protection.
As depicted in figs. 1 and 2, specifically, in the present embodiment, tank box 1 includes tank shell 13, heat-insulation layer 12 and tool
There is the inner water tank 11 of inner chamber 110, inner water tank 11 is arranged in tank shell 13, between inner water tank 11 and tank shell 13
