In a kind of optional embodiment, the gas valve body device also includes being arranged on the insulated heat body 7
The second temperature distortion body 9 and conductor piece 10；The second temperature distortion body 9 is used for by heat-conducting piece and common valve body assembly
The parts of temperature control are needed to connect；The second temperature distortion body 9 is additionally operable to electrically connect with the first end in firing pulse loop, institute
Conductor piece 10 is stated to be used to electrically connect with the second end of firing pulse circuit；It is conductive that the second temperature distortion body 9 is provided with first
Contact 11, the position that first conductive contact 11 is corresponded on the conductor piece 10 are provided with the second conductive contact 12；Institute
When stating that the second temperature distortion body 9 is lower in the raw and the conductor piece 10 is not bent, first conductive contact 11 with
Second conductive contact 12 is in contact so that the firing pulse loop turns on；The second temperature distortion body is by temperature time variance
Shape causes first conductive contact to be separated with second conductive contact；The second temperature distortion body 9 cooling when by
Gradually nature is reverted to so that first conductive contact 11 contacts again with second conductive contact 12.
Wherein, the firing pulse loop is used to control common valve body assembly automatic ignition, and in long logical state, but
If the firing pulse loop is constantly in conducting state, power consumption can be increased.And in the present embodiment, described
Two temperature distortion bodies 9 and the first temperature distortion body 5 are again by heat-conducting piece with needing the parts of temperature control to be connected；When described
When parts temperature rises, the second temperature distortion body 9, which deforms, causes the first conductive contact 11 and the second conductive contact 12 to separate, from
And disconnect igniting pulse circuit；Be moved to position of dying because the first temperature distortion body 5 deforms driving valve element 3 afterwards, valve element 3 every
Disconnected blast tube, the parts temperature decline, and the second temperature distortion body 9 returns to nature and causes the first conductive contact 11
Contacted again with the second conductive contact 12, again turn on firing pulse loop, zero of temperature control is needed in common valve body assembly
Part heats up again.Therefore in this thermostatic process, firing pulse loop only has of short duration time conducting, without being always maintained at work
Make state, reduce power consumption.
In a kind of optional embodiment, the second temperature distortion body 9 is bimetal leaf and has the second activity
End 91；The conductor piece 10 has the 3rd movable end 101；Second movable end 91 has passive layer side and active layers
Side；The passive layer side back of second movable end 91 is to the conductor piece 10；First conductive contact 11 is arranged on described
On the active layers side of second movable end 91；Second conductive contact 12 be arranged on the 3rd movable end 101 and with
First conductive contact 11 is corresponding.So as to, when the second temperature distortion body 9 is heated, its second movable end 91 with
Bent backwards to the direction of the conductor piece 10 so that first conductive contact 11 separates with second conductive contact.
It should be noted that bimetal leaf is wherein one of the second temperature distortion body 9 in the utility model embodiment
Kind implementation, other devices for being capable of temperature distortion are belonged within the protection domain of the utility model embodiment.For example, institute
Stating the second temperature distortion body 9 can also use in conventional thermostatic valve by thermal stretching, the temperature-sensitive bag of contract on cooling.Using energy during temperature rise
The temperature-sensitive bag enough expanded.
In a kind of optional embodiment, the passive layer side of second movable end 91 is towards first movable end
The active layers side in portion 51；Insulator 13 is additionally provided with the active layers side of first movable end 51；The insulator 13
Between the active layers side of first movable end 51 and the 3rd movable end 101；When the first temperature distortion body 5
When being in nature with the second temperature distortion body 9, the insulator 13 supports the 3rd movable end 101 to support or oppose
Bent to the direction of the second temperature distortion body 9, so that first conductive contact 11 and second conductive contact 12 divide
From；The thermal coefficient of expansion of two bimetal leaf is less than the thermal coefficient of expansion of the first temperature distortion body 5.Therefore, in original state
Under, firing pulse loop is breaking, further reduces power consumption, and improve safety in utilization.
