Example, the every other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made is belonged to
The scope of the utility model protection.
Fig. 1 is refer to, embodiment of the present utility model provides a kind of explosion-proof water tank of electric heater, and the electric heater is explosion-proof
Water tank includes being equiped with pressure-relief valve 4, the water inlet pipe of tank body 1 and water outlet on tank body 1 (press-bearing water tank), tank body 1
Water path valve 12 is connected at pipe.The inside of tank body 1 is provided with electric heater 2, wherein, electric heater 2 can be set
For electric heating tube, it can also be provided that the thermal source of similar electrothermal tube.As shown in figure 3, electric heater 2 can connect with temperature controller 3
In power supply (220V civil powers) to form electrical heating loop.
As shown in figures 1 and 3, the Kick type hand-reset in electrical heating loop can be series at by being also equiped with tank body 1
Derailing switch S2, the Kick type manual reset switch device of the present embodiment is described in detail below in conjunction with the accompanying drawings.
Specifically, Kick type manual reset switch device S2 includes derailing switch shell 5, it is necessary to which Manual press is just reducible
Hand-reset bar 6, the Kick type diaphragm 7 (can be convex and recessed) for promoting hand-reset bar 6, seals in the electricity in electrical heating loop
Contact 8, for connecting the contact portion piece 9 of two electric contacts 8 in closed state and entering for the position to manual release link 6
The spacing release link locating part of row,
The bottom of derailing switch shell 5 is welded on the circumference of Kick type diaphragm 7, the circumferential edges of Kick type diaphragm 7 again with
The circumferential edges of the perforate of tank body 1 carry out overlap joint full weld, and the bottom of Kick type diaphragm 7 is the internal cavity of tank body 1,
Kick type diaphragm 7 can be oppressed directly by the internal pressure of tank body 1, and one end of hand-reset bar 6 is placed in derailing switch shell 5
Inside, the other end of hand-reset bar 6 stretches out derailing switch shell 5, electric contact 8, contact portion piece 9 and release link locating part difference
Positioned at the inside of derailing switch shell 5, contact portion piece 9 is fixedly connected with hand-reset bar 6, electric contact 8 and release link locating part
It is located at the both sides of hand-reset bar 6 respectively, when it is implemented, two electric contacts 8 can correspond to the electrical heating being linked into shown in Fig. 3
A, b point position in loop, such Kick type manual reset switch device S2 are connected in series with electric heater 2 and the formation of temperature controller 3.
In the present embodiment, the Kick type diaphragm 7 can be preferably arranged to metallic membrane, naturally it is also possible to use other materials
The diaphragm being made is expected, as long as can reach that good performance can be implemented.
As shown in figure 1, release link locating part could be arranged to spacing steel wire 10, the upper-end part of driving of hand-reset bar 6 can be with
Thicker than lower end part, the upper-end part of driving of hand-reset bar 6 can offer limited impression 61 and is engaged with spacing steel wire 10.When prominent
When jump formula manual reset switch device is in closure state, the spacing steel wire 10 on the both sides of hand-reset bar 6 falls into hand-reset bar 6
Limited impression 61；When Kick type diaphragm 7 is pressurized, hand-reset bar 6 is promoted to move up, spacing steel wire 10 is swollen under force
Open, clamp the bottom of hand-reset bar 6；Because the upper-end part of driving of hand-reset bar 6 is thicker than lower end part, therefore, in spacing steel
Under the clamping action of silk 10, hand-reset bar 6 can not automatically reset.
As shown in figure 4, the release link locating part is it can also be provided that gag lever post 11, two gag lever posts 11 are located at manual respectively
The both sides of release link 6.Certainly, other locating parts can also be used according to actual needs, as long as can be played to manual release link 6
Good spacing performance can be implemented, and non-the present embodiment is limited.
As shown in Fig. 2 in the case of there is temperature controller and pressure-relief valve while failing, Kick type diaphragm 7 can be in water tank
The internal pressure of body 1 raises up when exceeding preset value (such as 1.0Mpa or other pressure values) promotes hand-reset bar 6 to move,
So as to drive contact portion piece 9 to leave electric contact 8, to cut off electrical heating loop.
Below by taking the common press-bearing water tank of in the market as an example, its rated pressure is 0.7MPa, and breakdown pressure is more than 1.2MPa.
When more than rated pressure, pressure-relief valve pressure relief drain, exhaust；If pressure-relief valve is blocked, tank pressure exceedes preset value 1.0MPa, this
When Kick type diaphragm will act (convex), promote hand-reset bar to cut off the electrical heating loop of electrothermal tube, so as to ensure water tank
Pressure is less than breakdown pressure.Afterwards, water tank cools to function of environment heat emission, and pressure is reduced in water tank, Kick type diaphragm return (recessed),
But hand-reset bar is limited part and blocked, electrical heating loop can not turn on automatically, it is necessary to artificial maintenance, just can manually make Kick type
Manual reset switch device resets.
In summary, the utility model can automatically cut off electrical heating in the case where temperature controller and pressure-relief valve fail simultaneously
Loop, can avoid water tank spalling or blast, substantially increase the security performance of Water tank for electrical water heater.
Above-described embodiment is the utility model preferably embodiment, but embodiment of the present utility model is not by above-mentioned
The limitation of embodiment, it is other it is any without departing from Spirit Essence of the present utility model with made under principle change, modify, replace
Generation, combination, simplification, should be equivalent substitute mode, are included within protection domain of the present utility model.
