Drain valve timer

Air compressor is used to produce the compressed air machine, directly by the motor to drive the compressor, the crankshaft to produce rotary motion, drive the connecting rod to make the piston reciprocating motion, cylinder volume change. Due to the change of pressure in the cylinder, the air enters the cylinder through the air filter through the inlet valve. In compression stroke, the cylinder volume reduction, the role of compressed air through the drain valve timer, the exhaust pipe, valve into the gas tank, when the exhaust pressure to achieve the rated pressure of 0.7 MPa is controlled by a pressure switch and automatic stop.
