Embodiment Construction
[0016] The specific structure of the present invention is further described in conjunction with the accompanying drawings.
[0017] Such as figure 2 As shown, the compressor exhaust device involved in the present invention includes an exhaust valve plate 2 , a valve stopper 3 , an exhaust seat 4 and bolts 8 . There is an exhaust hole 1 connected with the exhaust hole of the upper bearing 5 on the exhaust seat 2, and one end of the exhaust valve plate 2 and the valve stopper 3 is fixed on the exhaust seat 4 by a bolt 8, and the other end covers the exhaust port. Air vent 1 on the seat. The bolt 8 passes through the exhaust seat 4 along the thickness direction, and combines with the nut 7 on the other side of the exhaust seat to fix the exhaust valve plate 2 and one end of the valve stopper 3 on the exhaust seat 4 .

The invention relates to a compressor air drainage device, which comprises the following parts: air drainage valve, valve stop, air-out seat and fixation bolt, wherein one end of air drainage valve and valve stop is fixed on the air-out seat; the bolt screw traverses the air-out seat along the thickness direction and connects bolt nut on the other side of air-out seat. The device reduces air-out seat thickness and drainage bulk to the greatest degree, which improves the efficiency of compressor by affirming torque.
Description
technical field [0001] The present invention relates to compressors, and more particularly to exhaust devices for rotary compressors. Background technique [0002] In general, a rotary compressor consists of a motor part and a compressor part. The motor rotor of the motor part is arranged in the central cavity of the annular stator formed by the iron core and the winding. There is a crankshaft in the center of the rotor, and the lower end of the crankshaft is connected to the compressor part. The compressor section mainly includes a rolling piston connected to the crankshaft and a compression cylinder for housing the piston. The cylinder is composed of an upper bearing and a lower bearing and an annular cylinder wall that is fixedly combined on the compressor sealing shell between the upper bearing and the lower bearing. The crankshaft of the rotor of the motor part passes through the upper bearing and enters the compression cylinder, and the lower end of the crankshaft is...
