Accompanying drawing explanation
Accompanying drawing 1 is the section theory structure schematic diagram of " for the suction pressure balance regulator of charge inter cooling gas engine ".
Embodiment
See accompanying drawing 1, the present invention is comprised of balance adjustment body 4, diaphragm 15, connecting rod 12; Balance adjustment body 4 is disc-shaped structure, there is inner chamber, inner chamber is installed diaphragm 15, diaphragm 15 is separated into gaseous-pressure chamber 3 and air pressure chamber 2 inner chamber, has combustion gas inlet opening 5, combustion gas delivery outlet 16, gas pressure-reducing valve 7, combustion gas pressure relief valve 8, air-in 1, air pressure relief valve 13 on balance adjustment body; Combustion gas inlet opening 5 is connected with the delivery outlet of gas Combustion booster; Combustion gas delivery outlet 16 is connected with the combustion gas inlet opening of mixer; Gas pressure-reducing valve 7 is on the balance adjustment body between combustion gas inlet opening 5 and gaseous-pressure chamber 3; Pressure relief valve 8 is communicated with the gas inlet pipe road of gas Combustion booster; Air-in 1 is communicated with the output pipeline of air pressurizing unit; Air pressure relief valve 13 is communicated with atmosphere; Connecting rod 12 middle parts are fixed on the central position of diaphragm 15, accept the active force of diaphragm 15 and in balance adjustment body, do corresponding to-and-fro motion; Be positioned on the connecting rod of air pressure chamber 2 one end and have air pressure relief valve spring 6 and air pressure relief valve sheet 14, air pressure relief valve spring masterpiece is used on air pressure relief valve sheet 14, and air pressure relief sheet 14 is corresponding with the air pressure relief valve 13 on balance adjustment body; There is gas pressure-reducing valve sheet 11 at the connecting rod middle part that is positioned at one end, gaseous-pressure chamber, and gas pressure-reducing valve sheet 11 is corresponding with gas pressure-reducing valve 7; Combustion gas pressure relief valve spring 10 and combustion gas pressure relief valve sheet 9 are arranged at the connecting rod top that is positioned at one end, gaseous-pressure chamber, and combustion gas pressure relief valve spring-force driven dual is on combustion gas pressure relief valve sheet 9, and combustion gas pressure relief valve sheet 9 is corresponding with combustion gas pressure relief valve 8; Connecting rod can be done corresponding to-and-fro motion respectively in two ends Shang Xia 12 in pressure relief valve centre pilot hole separately.
In order to reduce spring 6, the impact of spring 10 on air, gaseous-pressure balance quality, the elastic force of spring 6, spring 10 should be as far as possible little, can overcome weight and the resistance to motion of valve sheet;
When static, combustion gas pressure relief valve 8 and air pressure relief valve 13 under the effect of valve spring 10 and valve spring 6 in closed condition;
In the middle of reality, gas Combustion booster great majority are to adopt " Roots blower "; Air pressurizing unit great majority are to adopt " exhaust-gas turbocharger "; The present embodiment explains with these two kinds of pressurized machines.
During engine start, gas Combustion booster (Roots blower) is followed engine rotation and is started working, the feature of Roots blower is also can efficient operation under slow-revving condition, output gaseous-pressure, and turbosupercharger cannot work when low speed, cannot delivery air pressure, therefore, in low engine speed operating mode, the atmospheric pressure of gaseous-pressure chamber 3 can be higher than the atmospheric pressure of air pressure chamber 2, diaphragm produces pressure difference between 15 two sides, the elastic force that the active force drivening rod 12 that this pressure difference produces overcomes spring 6 moves downward, open combustion gas pressure relief valve 8, the atmospheric pressure that Roots blower is produced releases, assurance flows to air pressure and the gaseous-pressure balance of mixer, if the combustion gas in gas inlet pipe road itself just has pressure (fuel gas source that has pressure), rely on opening in the time of cannot making combustion gas delivery pressure and air delivery pressure balance of pressure relief valve 8, diaphragm 15 meeting continuation generation active force drivening rods 12 further move downward and turn down gas pressure-reducing valve 7, (spring force is very little finally to make the gas pressure balance of gaseous-pressure chamber and air pressure chamber 2, impact on air pressure balance is disregarded at this), the gaseous-pressure of combustion gas delivery outlet 16 output just with air pressure balance, visible, the effect of combustion gas pressure relief valve 8 is at the output gaseous-pressure of Roots blower during higher than the delivery air pressure of turbosupercharger, release the delivery pressure of Roots blower, force the delivery pressure of Roots blower and the delivery pressure balance of turbosupercharger, when just there is pressure in fuel gas source itself, pressure relief valve 8 just cannot make gaseous-pressure and air balance, in this case, only have pressure loading valve 7 could reduce the atmospheric pressure of gaseous-pressure chamber 3, the delivery pressure of combustion gas delivery outlet 16 could with air pressure balance, now, the working condition of working condition of the present invention and existing pressure reducing regulator is in full accord, along with engine speed raising and load increase the weight of, the waste gas discharge capacity of motor increases sharply, turbosupercharger obtains the energy of need of work and works, when the air pressure of turbosupercharger output is during higher than the combustion gas delivery pressure of Roots blower, the atmospheric pressure of air pressure chamber 2 is just higher than the atmospheric pressure of gaseous-pressure chamber 3, diaphragm 15 produces the active force moving upward, the elastic force that diaphragm 15 drivening rods 12 overcome spring 10 moves upward, open air pressure relief valve 13, the unnecessary air of superpressure part is bled off, force turbosupercharger to be transported to the air pressure of mixer and the gaseous-pressure balance of roots blower output, meet the mixing condition of mixer needs, realized object of the present invention, sum up above-mentioned, the present invention has three control valves, the effect of first control valve 8 is delivery pressures of controlling gas Combustion booster (Roots blower), at the delivery pressure of gas Combustion booster during higher than the delivery pressure of air pressurizing unit, realize pressure release and control, guarantee the gaseous-pressure of gas Combustion booster output and the air pressure balance of air pressurizing unit output, the effect of second control valve 7 is when pressure relief valve 8 cannot make gaseous-pressure and air pressure balance by pressure release means, realizes combustion gas and reduces control, guarantees combustion gas delivery pressure and air delivery pressure balance, the effect of the 3rd control valve 13 is that the air delivery pressure of air pressurizing unit (turbosupercharger) is during higher than the combustion gas delivery pressure of gas Combustion booster (Roots blower), realize air pressure relief and control, by the means of pressure release, guarantee to be transported to air pressure and the gaseous-pressure balance of mixer, visible, by pressure release means, realize air pressure and gaseous-pressure balance is the obvious characteristic of control principle of the present invention, certainly also need to rely on traditional method of controlling (valve 7), on the other hand, coaxial (connecting rod) controlled three valves and should be thought main structure feature of the present invention, reasonable control that only in this way could realization order, adopt air intake pressurized system of the present invention, because air is from the through mixer of turbosupercharger, (for example: " balace weight " in documents of the present invention), so intake efficiency has reached diesel engine level there is no other device midway, main progress of the present invention has been to simplify the structure of balance sysmte, has reduced cost, has improved reliability, on the other hand, reduced intake resistance, improved intake efficiency, thereby improved maximum output, this advantage is also remarkable.
