Abstract
The utility model relates to a novel pneumatic control valve technology, belongs to the field of energy conservation of pneumatic systems, and mainly relates to control of a gas control circuit of a cylinder in the electrolytic aluminum industry. Air leakage quantity of the cylinder can be greatly reduced, the utilization rate of compressed air is improved, and a novel pneumatic control valve of which production process requirements can be guaranteed is produced. Based on the control of the gas control circuit of the cylinder in the electrolytic aluminum industry, the actuating gas pressure is reasonably matched and controlled by improving the pneumatic control circuit; when the cylinder extends out, a system is required to output power, and high-pressure gas connection is finished by switching of a series of valves; when the cylinder retracts, the series of valves are switched, and an air inlet of the cylinder is still connected to the high-pressure gas in a certain period of time, so that a piston of the cylinder can be smoothly started and retracted; and after a period of time, the air inlet of the cylinder is connected to low-pressure gas, so that the gas leakage quantity of the retracted cylinder is reduced.
Description
Technical field
The invention belongs to energy-saving field of pneumatic, relate to the pneumatic control system of aluminum electrolysis industry.
Background technology
The air consumption of aluminum electrolysis industry cylinder accounts for about 20% of whole plant compressed air usage quantity; Influence to whole factory energy consumption is most important, and the pressurized air service efficiency that effectively reduces the compressed-air actuated energy consumption of cylinder, raising cylinder is to solve the energy-conservation effective way of aluminum electrolysis industry pneupress system.
Cylinder is energy-conservation to be the gordian technique of energy-saving field of pneumatic in the aluminum electrolysis industry.Pneumatic system is being brought into play important effect because the adjusting of low, pollution-free, the easy care of cost, power output and working speed such as is very easy at advantage in industrial automation, but the energy consumption of cylinder accounts for pneumatic system total energy consumption significant proportion and capacity usage ratio is not high.In today that energy problem becomes increasingly conspicuous, the energy-conservation of cylinder has great significance to the energy-saving and cost-reducing of aluminum electrolysis industry.
Domestic and international existing pressure controlled valve is to adopt single force value output, that is: cylinder stretch out with withdrawal the time employing identical pressure.Because the requirement of technology input high pressure gas, and when cylinders retract the time, do not need high pressure when cylinder stretches out, and use high pressure can increase the spillage of system, so the single stage of pressure supply is not to supply with as required that air consumption is big, energy dissipation is serious.The present invention changes the pressure output of cylinder into two-stage output, can realize air feed as required, carries need being subordinate to gas efficient with gas of cylinder significantly, saves pressurized air.
Summary of the invention
The object of the invention:
For providing a kind of novel energy-conserving cylinder pneumatic circuit, aluminum electrolysis industry realizes energy-conservation 40%.

Technical scheme of the present invention:
When cylinder needed high-pressure air feed, wave triggered with high-pressure air source and is connected SV (3) action, and high pressure gas flow to throttling valve (1) through the vacuum breaker (2) that is connected with SV (3) and discharge; The inlet of throttling valve (1) is connected with the gas control interface of Pneumatic valve (4); Pressure in the Pneumatic valve control chamber rises, and Pneumatic valve (4) is exported high pressure gas, stretches out the output of completion power at the effect lower cylinder (5) of high pressure gas; After cylinder is finished the work; Wave triggers SV (2) switching-over that SV (3) resets and is connected with low-pressure gas source, and gas is connected with the gas control interface of Pneumatic valve (4) through the vacuum breaker (3) that is connected with SV (2), and the Pneumatic valve control chamber inserts low-pressure gas under the throttling action of throttling valve (1); Still the high pressure that keeps for some time; Thereby Pneumatic valve (4) is still exported high pressure gas in for some time, and cylinder (5) starts and begin withdrawal smoothly under the effect of high pressure gas, and source of the gas is through manual reducing valve (4) and pneumatic pressure-release valve (5); After reaching the regular hour; Along with the control intracavity gas is reduced to the low pressure that manual reducing valve (4) is set, Pneumatic valve (4) output low-pressure gas is accomplished the withdrawal action thereby cylinder continues to promote piston rod under the effect of low-pressure gas.
Because the pressure of input cylinder (5) reduces, the leakage of system reduces, and total air consumption is reduced, and realizes energy-conservation.
