The big channel 7 of the present invention can be such that it is cooperatively formed with passage aisle 6 according to the nozzle for requiring to install various different pore sizes
Certain gas flow ratio.
Passage aisle 6 is equipped with gas flow adjustment structure, and gas flow adjustment structure includes the regulating the qi flowing in the channels communicated with passage aisle 6
Hole 61, the interior adjusting needle 62 for being equipped with the gas flow size for adjusting passage aisle 6 in regulating the qi flowing in the channels hole 61, outer end and the external world in regulating the qi flowing in the channels hole 61
It communicates so that the adjusting needle 62 can be adjusted outside valve body, to adjust the gas flow of passage aisle 6.Adjust needle 62
Included locking functions ensure that position is constant after adjusting.
The present invention increases as electric current increases ratio valve port 46 upon actuation, at this time main valve lumen 52, proportioning valve epicoele 441
Pressure reduces, and 53 pressure of main valve cavity of resorption is constant, and voltage stabilizing valve port 32 is opened under differential pressure action at this time, supply main valve lumen 52, ratio
The main channel of example valve epicoele 441 is opened, and control valve is started to work, when 4 input current of proportioning valve becomes larger, outlet pressure become larger,
When input current become it is small when, outlet pressure become smaller, finally realize automatically controlled adjusting firepower size.
When ratio valve module electric current is constant when certain is put, in the case of admission pressure has fluctuation, intake pressure, which changes, gradually to be increased
Greatly, the air pressure of inlet chamber 13 and proportioning valve epicoele 441 increases at this time, increases from passage aisle 6 to the air pressure of main valve cavity of resorption 53, pushes open
Voltage stabilizing valve port 32, while the pressure of main valve lumen 52 and proportioning valve epicoele 441 increases, since ratio valve port 46 is invariable, this
When enter the air pressure of main valve lumen 52 and proportioning valve epicoele 441 due to big channel 7 gas flow than passage aisle 6 gas flow
Greatly, air-flow is obviously more increased than main valve cavity of resorption 53 fast so diaphragm 34 can be oppressed toward the movement of 53 direction of main valve cavity of resorption, at this time voltage stabilizing
Valve port 32 will become smaller, and pressure-stabilizing spring 333 effect under so that stable gas pressure is equilibrated to a pressure spot, at least will not with into
Air pressure fluctuation and there are big ups and downs, play voltage regulation result.
It is also same principle that admission pressure, which becomes smaller, and ratio valve port 46 is constant, and main valve lumen 52 and proportioning valve epicoele 441 need
The flow wanted will increase, but the gas flow due to big channel 7 under the influence of negative pressure is bigger than the gas flow of passage aisle 6,
Inlet end flow largely will enter main valve lumen 52 and proportioning valve epicoele 441 by voltage stabilizing valve port 32 and big channel 7, at one section
The flow for entering main valve cavity of resorption 53 in time will be since the limitation of passage aisle 6 makes 53 pressure of main valve cavity of resorption not reduce and flows back into
Main valve epicoele 51, this is allowed for, and 53 pressure of main valve cavity of resorption can maintain but 53 pressure of main valve cavity of resorption at this time can be than main valve lumen
52 and 441 pressure of proportioning valve epicoele is big so diaphragm 34 is allowed to open bigger to 52 direction of main valve lumen compressing voltage stabilizing valve port 32,
Charge flow rate more enters main valve lumen 52 and the supplement of proportioning valve epicoele 441 by voltage stabilizing valve port 32 and goes out caused by air inlet is reduced
The loss of the reduction of mouth pressure flow reduces pressure oscillation to improve outlet pressure within the scope of certain admission pressure, stable
Flow.
