Embodiment Construction
[0025] Such as figure 2 As shown, the exhaust valve assembly of the present invention includes a valve plate 1, an exhaust valve plate 2, a damping plate 3, a stopper 4, rivets 5, 6, a cylinder head gasket 7 and a cylinder head 8. The exhaust valve plate 2, the damper plate 3 and the stopper 4 are fixed on the valve plate 1 by rivets 5 and 6 (see also Picture 10 ). Of course, other common connection methods other than the rivets 5 and 6 can also be used in the valve group structure of the present invention, such as bolt connection.
[0026] Such as Figure 4 As shown, the exhaust valve plate 2 is provided with two exhaust valves 2c, 2d, and each exhaust valve 2c, 2d is itself symmetrical about its own centerline. Two exhaust valves 2c, 2d are respectively covered on the two exhaust ports 1e, 1f provided on the valve plate 1 (see also image 3 Shown). The root of the exhaust valve plate 2 is provided with two holes 2a, 2b for positioning and fixing after rivets 5, 6 are inserte...

The invention discloses an air exhausting valve set for a reciprocating compressor. The air exhausting valve set comprises a valve plate, an air exhausting valve sheet, a damping sheet, a limiter, a cylinder cover spacer and a cylinder cover, wherein the air exhausting valve sheet, the damping sheet and the limiter are fixed to the valve plate in a sequential overlapping manner; an air exhaustingvalve is arranged on the air exhausting valve sheet and covers an air exhausting port in the valve plate; claws are arranged at two sides of the limiter and are correspondingly arranged into two grooves in the valve plate in a pressing manner; two transverse strips are arranged on the cylinder cover spacer and are correspondingly pressed onto the claws at two sides of the limiter; two platforms are arranged on the cylinder cover and are correspondingly pressed onto the two transverse strips on the cylinder cover spacer. According to the air exhausting valve set for the reciprocating compressor, the air exhausting valve sheet is reliably fixed, thus automatic assembling is conveniently carried out, and the reliability of the air exhausting valve is further improved; the air exhausting valveset is particularly suitable for high-cooling-capacity commercial compressors.
Description
Technical field [0001] The invention relates to the technical field of refrigeration compressors, in particular to an exhaust valve group used for reciprocating compressors to discharge refrigerant out of cylinders. Background technique [0002] The movement of the compressor piston changes the pressure in the cylinder, which leads to the opening and closing of the suction valve plate. When the piston moves toward the end of the cylinder, the pressure in the cylinder is lower than the pressure in the compressor housing. At this time, the suction valve opens and the refrigerant in the housing enters the cylinder. When the piston moves toward the head of the cylinder, the pressure in the cylinder will increase; when the pressure in the cylinder is greater than the pressure in the housing, the suction valve closes; when the pressure in the cylinder continues to increase and is greater than the pressure in the exhaust chamber, The exhaust valve opens and the refrigerant enters the e...
