In conjunction with shown in Fig. 1 to Fig. 5, gas-cooker flow control valve, including valve body 1, the valve body 1 are equipped with and gas-cooker inner ring
The inner ring outlet passageway 2 of burner connection, the outer ring outlet passageway 3 being connect with gas-cooker outer annular burner, the inner ring outlet
Channel 2 is connected to outer ring outlet passageway 3, and the valve body 1 is additionally provided with the inlet channel 4 connecting with gas source, and the inner ring outlet is logical
The first solenoid valve 5 is equipped between road 2 and outer ring outlet passageway 3, the inlet channel 4 is equipped with second solenoid valve 6, and the inner ring goes out
Flow control assembly 7 is equipped between gas channel 3 and inlet channel 5, the flow control assembly 7 by partially forming as follows, including
Flow control shell 8, main fixed column 9 is equipped in the flow control shell 8, and one end of the main fixed column 9 is connected with solid
Fixed column motor 10 is streamlined column core 11 in the middle part of the main fixed column 10, which is symmetrically arranged with flow tune
Nodal plate 12, vertical center one end of the flow regulating plate 12 passes through main 9 one end of fixed column and is connected with adjustment sheet motor 13, described
The motor protecting cover 14 being tightly connected with flow control shell 8 is equipped with outside adjustment sheet motor 13.
Implementation process of the invention: combustion gas enters valve body 1 by inlet channel 4 and is flowing by the unlatching of second solenoid valve 6
Under the flow adjustment effect for measuring control assembly 7, hence into inner ring outlet passageway 2, finally enters inner ring burner and starts to burn,
When increasing firepower, enlargement discharge is carried out by flow control assembly 7, after the unlatching of the first solenoid valve 5, into outer ring outlet passageway 3,
Outer annular burner is eventually entered into burn, wherein in the whole process, the first solenoid valve 5 and second solenoid valve 6 and flow control
Component 7 processed cooperate it is practical, the servoelement of electromagnetic component and flow control assembly therein by the same control circuit into
Row control.
And the control principle of flow control assembly 7 is, before combustion gas passes through flow control assembly 7, main fixed column 9 can be solid
Under the action of fixed column motor 10, it is gradually adjusted to aeration status from blocking state, specifically in conjunction with attached drawing, it can be seen that blocking shape
When state, the posture of main fixed column 9 is that the outer edge contour 18 of the flow regulating plate 12 of wherein side is blocked among fuel gas path, because
This combustion gas is in blocking state, and in the rotary course of main fixed column 9, the intersection of outer edge contour 18 and inner edge profile 19 will
It is come out from the internal rotating of flow control shell 8, and forms gas passage, combustion gas at this time starts to flow, and is adjusted by two sides flow
The space that piece 12 and flow control shell 8 are formed carries out flow adjusting；When the flow control of flow regulating plate 12 and opposite side
When spacing between shell 8 processed is smaller, due to narrow pipe effect, flow velocity is accelerated, if former speed enters burner, when will lead to igniting
There is deflagration phenomenon, controls the improper ability that will appear risk, therefore the autonomous posture of flow regulating plate 12 is utilized to change, so that
Although airintake direction causes flow velocity to be accelerated since narrow pipe effect occurs in slot, the space of outgassing direction is become larger, further
It says and is exactly that the flow regulating plates 12 of two sides shortens relative to the relative spacing of airintake direction side, and the relative spacing of outgassing direction
Become larger, so that outgassing direction generates a buffering reflux space, so that flow velocity is reduced, so that deflagration phenomenon when combustion gas occurs generally
Rate substantially reduces.
In addition, the posture when main fixed column 9 changes on the way, streamlined column core 11 can also play water conservancy diversion and drainage, into
One step controls the flow velocity of combustion gas and utmostly eliminates sinuous flow and flow-disturbing phenomenon, when main fixed column 9 is in complete
When aeration status, that is, front-rear direction and combustion gas when flowing to consistent of streamlined column core 11, the trim process of flow is just by two
The flow regulating plate 12 of side is completed, and the relative distance on front-rear direction is adjusted by flow regulating plate 12, to change air inlet
The port size of direction and outgassing direction, so that the flowing of fuel gas flow is controlled, this partial routine whole process can lead to
It crosses and comes with the servopackage of flow control assembly 7 automatically controlled, therefore do not need artificially to control, exposed dirt will not be caused to enter shadow
Service life is rung, combustion gas can also obtain accurate flow control, so using effect is good, high degree of automation is accurately obtained guarantor
Card, also securely and reliably.
