Using technical scheme, combustion gas input port is provided with electromagnetic valve A as main switch, and each delivery outlet separately sets
There is electromagnetic valve B, to improve sealing safety coefficient；Each cut-off electromagnetic valve and pressure regulating device carry out action respectively so that
All parts undertake respective effect, will not interfere；Described combustion gas adjust stable-pressure device be provided with low discharge adjust and
Big flow machine
Tool is spacing；Outside permanent-magnetic field is formed using permanent magnet, adopt a solenoid middle, when adjusting by
On coil
Curent change so that the active force between coil and peripheral permanent magnet is changed and change coil stroke, due to
Coil is soft
There are not hysteresis in property material, therefore be quick on the draw；When coil displacements reach maximum set value, big flow is spacing
Nut tangles
Buckle, make coil can not displacement again, the maximum opening of pressure regulation restriction is limited；By adjusting low discharge
Spacing spiral shell
Nail, can carry out preconditioning to the minimum aperture of bulb stopper and pressure regulation restriction.

Fig. 3 is the structural representation of part of the present invention；
Fig. 4 is the structural representation of the embodiment of the present invention 2.
Specific embodiment
The invention will be further described with reference to the accompanying drawings and examples.
Embodiment 1
A kind of adjustable gas-combustion proportioning valve as shown in Fig. 1,2,3, including valve body, described valve body includes Gas Pipe
Road 17 and output lid 18, output lid 18 band dual-coil electromagnetic valve double air vent, it is provided with blast tube 2 in described gas pipeline 17, described
Combustion gas delivery outlet 16 is set, combustion gas delivery outlet 16 is located on the output lid 18 of electromagnetic valve B20 control, electromagnetic valve in output lid 18

Entrance 15 connects with combustion gas delivery outlet 16, is provided with electromagnetic valve A19, electromagnetic valve between described combustion gas input port 15 and blast tube 2
The rated voltage of A19 is 24V, is provided with combustion gas and adjusts stable-pressure device between described gas pipeline 17 and output lid 18.
Described combustion gas adjusts stable-pressure device and includes bulb stopper 3, and described gas pipeline 17 outlet is provided with bulb stopper 3, and bulb stopper 3 upper end sets
There is sphere, described sphere separates formation pressure regulation restriction 1 with gas pipeline 17 outlet, bulb stopper 3 passes through pressure sensitive epithelium 4 He
Pressure responsive disc 5, is equipped with the projection sealing in pressure sensitive epithelium 4, bulb stopper 3 lower end is cased with spring A6 and installs online
Enclose 10 tops, in coil 10, be provided with iron core 8, coil 10 periphery is equipped with permanent magnet 9 and upper pole shoe 7, the middle lower end of coil 10 is cased with
External member 11, the middle lower end of coil 11 is arranged on and can inside and outside adjust in the stop nut 12 controlling combustion gas maximum stream flow, described external member
It is provided with below 11 and inside and outside can adjust the stop screw 14 controlling combustion gas minimum discharge, set between described external member 11 and stop screw 14
There is spring B 13.
During use, electromagnetic valve A19 is the main switch of proportioning valve, and it has combustion gas to flow into gas pipeline 17 when being energized；During power-off,
Combustion gas is cut off.After electromagnetic valve A19, the combustion gas flowing into proportioning valve adjusts stable-pressure device to combustion gas stream.Electromagnetic valve B20 is two
The second cut-off threshold switch of gas outlet.Only guarantee that electromagnetic valve A19 and electromagnetic valve B20 is energized when opening, combustion gas ability
Flow out output lid 18.Bulb stopper 3, pressure sensitive epithelium 4, pressure responsive disc 5, stop nut 12, stop screw 14 are worked in coordination, control
The size of gas flow processed and stable：When being passed through the increase of coil 10 electric current, it is magnetic field-enhanced that coil 10 produces, and this magnetic field is with forever
The repulsive force of magnet 9 increases, then coil 10 promotes bulb stopper 3 to shift up, and bulb stopper 3 is increased with the gap of pressure regulation restriction 1, i.e. phase
Gas flow is answered to increase；Conversely, coil magnetic field weakens, repulsive force reduces, and corresponding gas flow reduces.
When the current constant being passed through coil 10, when proportioning valve inlet pressure produces fluctuation, proportioning valve can be going out air pressure
Power is stablized in certain scope：When admission pressure increases, under the effect of the pressure, pressure sensitive epithelium 4 rouses downwards, drives
