Description
Technical field
It the utility model is related to a kind of valve, more particularly to a kind of valve applied to gas-cooker.
Background technology
Gas valve in various gas kitchen ranges, it is the manual operating valve for controlling source of the gas supply.Household gas utensils typically have
There are interior ring fire and an outer ring fire, common binary channels gas valve, which generally comprises, internal has inlet channel, inner ring outlet passageway and outer
The valve body of ring outlet passageway, valve body is interior to be provided with revolvable valve element, and valve element bottom is provided with venting cavity, and being equipped with valve body to drive
The valve rod of Spool rotating, valve rod can together rotate with movable valve plug, be provided with to connect inlet channel in the venting cavity side wall of valve element
With the series regulation fire hole not of uniform size of outer shroud outlet passageway, and to connect inlet channel and inner ring outlet passageway it is in
The inner ring fire hole of arc.
In use, the inner ring outlet passageway of valve body and outer shroud outlet passageway end are connected use with nozzle, inner ring outlet leads to
Road finally communicates with the internal ring portion in kitchen range, and outer shroud outlet passageway finally communicates with the outer portion in kitchen range, and user can pass through
The knob that is arranged on guidance panel and operating valve lever, typically first press knob and rotate counterclockwise, you can the band movable valve plug inverse time
Pin rotates, and big fire hole and arc-shaped slot on valve element is connected with the inlet channel in valve body, and source of the gas is from inlet channel
It is divided into independent two-way after, is connected all the way via venting cavity, regulation fire hole with outer shroud outlet passageway, another way is via ventilation
Chamber, inner ring fire hole connect with inner ring outlet passageway.
When adjusting the intensity of a fire, turning knob is only needed, drives Spool rotating, utilizes the series regulation fire hole and outer shroud of different pore size
Outlet passageway communicates the intensity of a fire regulation for realizing outer ring fire, and in the state of outer ring fire is adjusted to zero, interior ring fire is still kept out
Fire.During valve core rotation, it can not be carried out because the pore size of inner ring fire hole is constant all the time, that is, in the intensity of a fire of interior ring fire
Regulation.The gas-cooker of this mode, it is interior because the only outer ring fire intensity of a fire diminishes when fried egg or stand cake is carried out with small fire
The firepower of ring fire is still larger, and this can make it that the center section of fried egg or thin pancake is easily burnt, influence the quality of food.
Existing this gas valve, the big fire hole on its valve element perisporium are circumferentially arranged at intervals with small fire hole, the distance at interval
The revolvable angular dimension of institute is related during intensity of a fire size is adjusted to knob, just because big fire hole is circumferentially spaced with small fire hole
Set, valve element either rotates, adjusted from big fire to small fire clockwise or counterclockwise, or is adjusted from small fire to big fire and have one
Individual neutral position, the neutral position is the valve element perisporium between big fire hole and small fire hole, because the design defect of existing valve element.
Prior art does not change linearly during valve core rotation when flow comes out, particularly in big fire to the excessive of small fire
In the stage, changes in flow rate is not linear, ratio declines, it is possible to unbalanced, nonlinear feature is presented.
Feeling for actual user is that firepower size variation becomes big suddenly in large and small fire handoff procedure when using, or is not had
Change, to during small fire again diminish suddenly.The defects of regulation is unstable, easily flame-out during large and small fire regulation be present, to reality
Using bringing many inconvenience.
Therefore, those skilled in the art have made effort, several linear flow gas valves, such as Patent No. are disclosed
ZL201310388568.0 Chinese invention patent《A kind of linear flow cock gas valve》(Authorization Notice No. CN
103423480B)；And for example Patent No. ZL201310328453.2 Chinese invention patent《A kind of tune of linear adjustable firepower
Save valve》(Authorization Notice No. CN 103438245B).Similar can also refer to CN105715818A, CN105650306A etc..
The cross facet between the inner and outer rings outlet passageway in the circular hole and valve body on valve element in technology disclosed above it is big
It is small to adjust firepower size.Following deficiency be present in this kind of design：
First, in rotary course, the mutability of cross facet area clearly, causes the existing big thermal transfer of gas valve outer shroud
The effective angle of small fire is saved even less than 15 °, user is difficult the firepower that must quickly and easily adjust oneself needs.
Second, the inner and outer rings gas output of valve body, it is to have on valve element single hole and corresponding valve channel to adjust, leads
The gas output for causing inner and outer rings is independent, and incoherent.It is difficult its firepower is synchronously changed in design, while in order to continue
When outer shroud is closed, inner ring is most big fire, and current gas valve is closed since 90 ° counterclockwise to outer shroud, and interior ring firepower is always
Relatively large.This reason causes user when in use, find firepower it is uneven, often fried egg or stand cake when among easily
Jiao falls, and have impact on the delicious and attractive in appearance of food.
3rd, the structure of current gas valve can not meet the good conditioning function of some conventional firepower, can not for example have one it is good
The firepower section of tune, its inside and outside ring firepower is synchronous small, and general power is constant in a less angular range, is easy to
User spreads out cake, fried egg, Baoshang, and this firepower section is very easy to be transferred to.
