during operation, when air conditioning leads to cold air hole 22 and air conditioning passageway 21, air conditioning chamber 44 flows into in the two 433 of air conditioning passageway, air conditioning directly contacts with air blocking sheet 6, because air blocking sheet 6 is made by the heat-insulating material, consequently, the inside air conditioning of two 433 of air conditioning passageway can not cool off memory metal spring 61 through air blocking sheet 6, thereby guaranteed that memory metal spring 61 keeps out of shape when the temperature is higher than operating temperature in cylinder 3, and then make air blocking sheet 6 always be in the open mode when the temperature is higher than normal operating temperature in cylinder 3, thereby avoided leading to air blocking sheet 6 unable normal open because of air conditioning cools off temperature to memory metal spring 61, make the inner wall of cylinder 3 always be in the high temperature state and lead to air compressor's power consumption to increase, the volume of admitting air reduces and life reduces.
The specific working process is as follows:
when the double-cylinder air compressor is in operation, when the double-cylinder air compressor compresses low-pressure air in the working volume of any one of the cylinders 3, the motor 13 is started, the motor 13 rotates to drive the eccentric wheel 11 to synchronously rotate, so as to drive the push blocks 12 on the two sides of the eccentric wheel 11 to do reciprocating linear motion, when any one of the cylinders 3 of the double-cylinder air compressor performs a compression process, an air suction process is performed in the other cylinder 3, when any one of the cylinders 3 of the double-cylinder air compressor performs a compression process, an external air cooling device synchronously introduces cold air into the cold air valve 5 through the cold air inlet 51, at this time, because the connecting rod 2 is provided with the cold air hole 22 and the cold air channel I21, and the cold air valve 5 is internally provided with the first shaft sleeve 52, the first shaft sleeve 52 wraps the cold air hole 22 on the connecting rod 2, when the connecting rod 2 moves to one side of the valve plate 7 under the drive of the push block 12, the cold air hole 22 on the connecting rod 2 gradually exposes from the first shaft sleeve 52, the cold air in the cold air valve 5 flows into the cold air cavity 44 in the piston 4 through the cold air hole 22 and the cold air channel one 21, and is sprayed onto the inner wall of the cylinder 3 through the cold air channel two 433 on the air ring 43, when the cold air hole 22 moves to the inside of the cylinder 3 along with the connecting rod 2, the cold air hole 22 is covered by the second sleeve 53 in the cylinder 3 again, the cold air in the cold air valve 5 flows into the cold air channel two 433 through the cold air hole 22 via the cold air channel one 21 and the cold air cavity 44, because the cold air channel two includes the cold air nozzle one 431, and the cold air nozzle one 431 is vertical to the inner wall of the cylinder 3, the cold air is sprayed out through the cold air nozzle one 431 after passing through the cold air hole two 433, and directly contacts with the inner wall of the cylinder 3 corresponding to the cold air nozzle one 431, and the cold air in the cold air valve 5 flows into the cold air channel two 433 through the cold air hole 22 via the cold air channel one 21 and the cold air cavity 44, because the second cold air channel 433 includes the second cold air nozzle 432, and the outlet direction of the second cold air nozzle 432 is inclined toward the inner wall of the cylinder 3, the cold air in the second cold air channel is sprayed out through the second cold air nozzle 432 and directly contacts with the inner wall of the cylinder 3, when the piston 4 moves toward the valve plate 7 under the driving of the motor 13, because the first oil ring 41 and the second oil ring 42 on the piston 4 both contact with the inner wall of the cylinder 3 and are inclined toward one side of the inner wall of the cylinder 3, the second oil ring 42 will continuously contact with the inner wall of the cylinder 3 during the process that the piston 4 moves toward the valve plate 7 to compress the air in the working volume of the cylinder 3, the second oil ring 42 is made of a heat conducting material, and the second oil ring 42 can conduct part of the heat on the inner wall of the cylinder 3 to the interior of the piston 4 through the second oil ring 42 during the contact of the inner wall of the cylinder 3 and then be cooled and cooled by the cold air in the cold air cavity 44, when the temperature in the cylinder 3 is higher than the normal working temperature of the cylinder 3, the memory metal spring 61 is heated to be compressed and deformed, and further drives the air blocking sheet 6 fixedly connected with the memory metal spring 61 to displace, because the air blocking sheet 6 is hinged above the outlet of the first cold air nozzle 431, after the memory metal spring 61 is heated and deformed, the memory metal spring 61 drives the air blocking sheet 6 to be opened upwards, so that the cold air in the second cold air channel 433 sprays the cold air to the inner wall of the cylinder 3 through the first cold air nozzle 431 and the second cold air nozzle 432, so as to cool and cool the inner wall of the cylinder 3, when the temperature in the cylinder 3 does not exceed the normal working temperature of the cylinder 3, the memory metal spring 61 is in a natural state, the air blocking sheet 6 is positioned above the first cold air nozzle 431, the cold air flows into the second cold air channel 433 through the cold air hole 22, the first cold air channel 21 and the cold air cavity 44, the air conditioning is direct to contact with the air blocking sheet 6, and because the air blocking sheet 6 is made of heat insulating materials, the air conditioning in the air conditioning channel II 433 can not cool the memory metal spring 61 through the air blocking sheet 6, so that the memory metal spring 61 is guaranteed to be deformed when the temperature in the cylinder 3 is higher than the working temperature, and the air blocking sheet 6 is always in an open state when the temperature in the cylinder 3 is higher than the normal working temperature.
