Abstract
The utility model relates to a novel electronic control valve technology, and belongs to the energy-saving field of a pneumatic system. The utility model mainly relates to a novel electronic control valve mainly used for air control circuits for air cylinders of the electrolytic aluminum industry, which can greatly reduce the air leakage of the air cylinder, enhance the compressed air utilization ratio, and meet the requirements on production technologies. The novel electronic control valve can reasonably control the input pressure of the air cylinder by improving the air control circuit. When a shell of the air cylinder is broken, the power of a system is required to be output, and high pressure air access through the switchover of a series of valves; and when the air cylinder shrinks, the decompressed low-pressure air accesses so as to lower the air leakage.
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 adopt identical pressure.Because the requirement of technology input high pressure gas, and do not need high pressure when cylinders retract the time 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 output of the pressure of cylinder into two-stage output, can realize air feed as required, and that improves cylinder significantly use gas efficient, saving pressurized air.
Summary of the invention
Purpose of the present invention:
For the crust breaking cylinder of aluminum electrolysis industry provides a kind of novel electric-controlled type crust breaking dividing potential drop air feed control loop, thereby realize that crust breaking cylinder consumption moral can 40%.
