Description
Technical field
The application is related to Household water heating stove technical field, especially, is related to one kind and is used for Household water heating stove, has freeze proof work(
The explosion-proof valve of energy, and there is the Household water heating stove of this explosion-proof valve.
Background technology
At present, civil water heating coal stove according to existing national standard it is necessary to above the water jacket of heating furnace install internal diameter not
Explosion-proof valve less than 25mm.When heating furnace accident pressure-bearing, explosion-proof valve film can rouse brokenly, makes stove pressure release, plays explosion-proof work(
Can, thus ensureing the operation safety of heating stove.
But, the condition that the explosion-proof valve of existing employing is used is it is necessary to ensure that the water in Heating stove water pipe is in flow-like
State.And work as indoor temperature and be less than zero degree for a long time, in water jacket during water freezing, existing explosion-proof valve due to the restriction of its structure, and not
Explosion-proof can be played, there is very serious potential safety hazard.
For example, north this winter most area meets with the weather of extremely trembling with fear do not met, a lot of urban residents users 30 years
Thrifty due to living, just start raw stove of lighting a fire when weather is terribly cold.At that time, indoor temperature has been significantly less than freezing point, furnace water jacket
Freeze over freezes in fact.And some users shortage uses general knowledge, blindly point burns stove, easily causes quick-fried stove accident.Only in Shandong
Province region winter in 2015 has just led to a lot of furnace lifting and has ruined the tragedy that people dies.The scene of the accident is a piece of in disorder, and wall falls room and collapses and disastrously can't bear
See！
For these reasons, a kind of explosion-proof valve need to be designed and developed in pole, even if burning stove in stove complete icing condition down-firing,
Also can be in stove pressure-bearing, drum breaks explosion-proof diaphragm pressure release, thus more effectively ensureing the safety of life and property of user.

When cold weather indoor temperature is less than zero degree, the circulation water freezing in heating furnace water jacket, or even complete for a long time
When freezing, if user lacks, using general knowledge, blindly point burns stove, because the explosion-proof diaphragm of the anti-freezing explosion-proof valve of the application is close
The inwall of water jacket and immersed the recirculated water of water jacket, therefore when heating furnace furnace body inner housing is heated, the circulation of water jacket inwall
Water can be heated first.Due to adopting damascene structures, explosion-proof diaphragm can be added first anti-freezing explosion-proof valve near when putting and burning stove
The water jacket inwall of heat, even if under icing indoors and the frozen extreme case of furnace water jacket, the ice sheet near explosion-proof diaphragm is first
First can be melted, and not affect its explosion-proof.Even if furnace water jacket inwall order baked wheaten cake stove moment steep temperature rise and rupture pressure disc
When ice sheet near piece is not melted completely, due to the damascene structures of explosion-proof diaphragm employing, the ice sheet near explosion-proof diaphragm is very
Thin, the pressure that explosion-proof diaphragm also can be produced by water jacket inwall ice sheet transient evaporation breaks through, and then realizes pressure release, really plays explosion-proof
Function.
Above to a kind of anti-freezing explosion-proof valve for Household water heating stove provided herein, it is described in detail, this
Apply specific case in literary composition the principle of the application and embodiment are set forth, the explanation of above example is only intended to
Help understands the present processes and its core concept；Simultaneously for one of ordinary skill in the art, according to the think of of the application
Think, all will change in specific embodiments and applications, in sum, it is right that this specification content should not be construed as
The restriction of the application.
