Description
Technical field
The present invention relates to fluid valve field, in particular to a kind of electric-controlled gas valve.
Background technology
Burnt gas valve on the market is mainly armstrong's patent valve at present, and it is mainly provided with valve body is used for valve opening and closing
Movable part, movable part includes valve rod and handle, can make valve opening and closure by rotational handle, the defects of this kind of valve
It is that valve rod and handle are exposed, easily makes dirty during using hand rotational handle, influence service life and be difficult to clean, in addition, uses
Shi Bixu hand switches, it is not only troublesome in poeration, but also Automated condtrol can not be carried out, so the use for being difficult to meet people will
Ask.
The content of the invention
It is contemplated that at least solves one of above-mentioned technical problem in correlation technique to a certain extent.Therefore, this hair
Bright to propose a kind of electric-controlled gas valve, it can pass through automatically controlled automatically open and close valve.
To achieve the above object, technical scheme is as follows：
A kind of electric-controlled gas valve, including valve body, valve body are provided with admission line, in addition to the control panel on valve body, valve
Body forms closed air cavity with control panel, and admission line connects with air cavity, and control panel is provided with the outlet pipe communicated with air cavity
And electrothermal piece, electrothermal piece are connected with the deformable member for extending to outlet pipe, deformable member is provided with close to one end of outlet pipe
Effect and the plug of outlet pipe.Under conventional sense, plug blocks outlet pipe, and electrothermal piece switches on power during use, electrothermal piece
Generate heat and heat is sent to deformable member, now deformable member temperature distortion, the plug for blocking outlet pipe is removed, open outlet
Pipeline.Powered when electrothermal piece is cut off, electrothermal piece does not generate heat, and the heat of deformable member is taken away in the combustion gas in air cavity, deformable member temperature
Decline and reply original state, plug is blocked outlet pipe and complete closing motion.
As the further improvement of above-mentioned technical proposal, deformable member includes square sheet, and square sheet is provided with plug
One end is symmetrically arranged with flanging.
As the further improvement of above-mentioned technical proposal, deformable member is provided with the through hole of installation plug.
As the further improvement of above-mentioned technical proposal, the material of deformable member includes thermo bimetal.
As the further improvement of above-mentioned technical proposal, thermo bimetal includes being combined by the metal of a variety of different coefficients of expansion
Into composite.
As the further improvement of above-mentioned technical proposal, control panel is provided with the electrode slice being powered for electrothermal piece.
The beneficial effects of the invention are as follows：The present invention is by using the setting electrothermal piece inside gas valve and the change with plug
Shape part, deformation is brought it about to deformable member heating using electrothermal piece, has reached and has automatically controlled the effect that gas valve is opened and closed,
Eliminate the tedious steps of user's hand switch gas valve.
Brief description of the drawings
It is described further below in conjunction with accompanying drawing and example.
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the internal structure schematic diagram of the present invention.
Fig. 3 is another internal structure schematic diagram of the present invention.
Fig. 4 is the structural representation of the deformable member in the present invention.
Embodiment
Embodiments of the invention are described below in detail, the example of the embodiment is shown in the drawings, wherein from beginning to end
Same or similar label represents same or similar element or the element with same or like function.Below with reference to attached
The embodiment of figure description is exemplary, it is intended to for explaining the present invention, and is not considered as limiting the invention.
Referring to figs. 1 to Fig. 3, a kind of electric-controlled gas valve, including valve body 1, valve body 1 are provided with admission line 11, in addition to peace
Control panel 2 on valve body 1, preferably, the quantity of the control panel 2 of the present invention is arranged to 2, it is symmetrically arranged on valve body 1
Both sides, in other embodiment, control panel 2 may be configured as one or more.The peripheral sealing of valve body 1 and control panel 2 cooperatively forms
Closed air cavity 3, admission line 11 connect with air cavity 3, and control panel 2 is provided with the outlet pipe 21 and electricity communicated with air cavity 3
Warmware 4, the outside of control panel 2 is stretched out for the electrode slice 41 that electrothermal piece 4 is powered, electrothermal piece 4, which is connected with, extends to outlet pipe
21 deformable member 5, deformable member 5 are provided with effect and the plug 6 of outlet pipe 21 close to one end of outlet pipe 21.Conventional sense
Under, plug 6 blocks outlet pipe 21, and electrode slice 41 switches on power during use, and electrothermal piece 4 generates heat and heat is sent to deformable member
5, the now temperature distortion of deformable member 5, the plug 6 for blocking outlet pipe 21 is removed, direction is transported as shown in arrow in Fig. 2 air cavitys 3
It is dynamic, so as to open outlet pipe 21.Powered when electrode slice 41 is cut off, electrothermal piece 4 does not generate heat, and the combustion gas in air cavity 3 is deformable member 5
Heat take away, the temperature of deformable member 5 is lowered back to multiple original state, make plug 6 block outlet pipe 21 complete closing motion.Deformation
The material of part 5 includes thermo bimetal, and thermo bimetal includes the composite being combined into by the metal of a variety of different coefficients of expansion.This
In invention, the metal of described thermo bimetal and a variety of different coefficients of expansion is prior art, and this place repeats no more.
Reference picture 4, deformable member 5 include square sheet, and one end that square sheet is provided with plug 6 is symmetrically arranged with flanging
51, deformable member 5 is provided with the through hole 52 of installation plug 6.When deformable member 5 is heated, because the metal of the different coefficients of expansion is in temperature
Caused size and Volume Changes are inconsistent during change, it may appear that the phenomenon of deformation, and deformable member 5 is arranged to flanging 51
Square sheet, its controllable deformable member 5 are deformed with the direction of arrow shown in Fig. 4 so that plug 6 can follow deformable member 5 deform and
It is mobile, reach the purpose opened and close outlet pipe 21.
Although embodiments of the invention have been shown and described above, it is to be understood that above-described embodiment is example
Property, it is impossible to limitation of the present invention is interpreted as, one of ordinary skill in the art within the scope of the invention can be to above-mentioned
Embodiment is changed, changed, replacing and modification.
