Description
Technical field
The present invention relates to a kind of reciprocal compressor, particularly valve block structure of reciprocating type refrigerator refrigeration compressor of being used for.
Technical background
The motor that reciprocating type freezer compressor generally comprises valve group, cylinder, piston, connecting rod, bent axle and drives their runnings, the pump housing that is made of them is placed in the housing of a sealing.By the running of motor, drive crankshaft ﹠ connecting and promote reciprocating motion of the pistons, suction valve chip in the valve group and exhaust valve plate are intermittently opened, are closed under piston action, constantly suck and discharging refrigerant, form interrupted refrigeration agent stream thus.Piston in each compression process at the end, the residual volume that forms between pistons end and valve plate is referred to as clearance volume, clearance volume is extremely important to the influence of compressor efficiency, clearance is more little, and the residual gas shared gas volume that expands again when air-breathing is just more little, and exhaust efficiency is just high more.And the spatial volume that air release valve hole forms in clearance volume has occupied the main share of total clearance.
The valve block structure of compressor is made up of the valve plate that adopts steel plate, powdered metallurgical material to make and the exhaust valve plate that is riveted on valve plate and snubber usually, and clearance volume is higher, and compressor efficiency is general.As shown in Figure 1, the outlet valve part in the compressor valve block structure of traditional design is made up of cylinder head 101, valve plate 102, rivet 103, exhaust valve plate 104 and snubber 105, and 110 is air release valve hole.The conventional valve plate structure adopts the plane valve plate, and thickness generally more than 2.5mm, is fixed on exhaust valve plate 104 and snubber 105 on the valve plate 102 with rivet 103.Can see that the thickness of the exhaust port 110 of conventional construction valve plate is bigger, makes clearance bigger.Along with more and more higher to requirements of saving energy in recent years, also more and more higher to the efficient requirement of compressor.Therefore, in the prior art of valve block structure, adopted the female valve plate technique, promptly exhaust valve port is lower than the valve plate plane morely, and thickness is 1.4mm～1.5mm, can significantly reduce the compressor redundant gap volume like this.Shown in Figure 2 be wherein a kind of; its delivery valve seat is in the position that is lower than plane 232,233 on the valve plate 202; make that exhaust port thickness is less; help the minimizing of clearance; in groove; exhaust valve plate 203, buffer substrate tablet 204 and snubber 205 be closed assembly successively, and buffer substrate tablet 204 plays buffer function to exhaust valve plate 203 during for the big aperture of exhaust valve plate 203, thus protection exhaust valve plate 203.But, just because of exhaust valve port is lower than plane on the valve plate, adopt traditional Double End grinding can not finish the abrasive machining of exhaust valve port, need to increase special exhaust valve port grinding equipment, and because that the parallelism of recessed exhaust valve port plane and exhaust valve plate mounting plane not as the flat valve plate, can cause valve port to grind the rate that rolls off the production line is higher.Though spill valve plate exhaust valve port is lower than the valve plate plane, but the grinding size requirement for two planes of valve plate is still very high, because this structure be assemblied in the valve block limit stoper end flat 232a of groove and 233a should be as far as possible with valve plate on plane 232,233 flush, help the cylinder head end face area like this and compress, the valve plate grinding capacity has determined the size between valve plate plane and the bottom portion of groove.If the size between valve plate plane 232,233 and the bottom portion of groove is bigger than normal, then limit stoper plane 232a, the 233a of An Zhuaning can be lower than valve plate 232,233 planes, can cause limit stoper loosening, and as less than normal, then limit stoper plane 232a, 233a exceed valve plate 232,233 planes, cause cylinder head to compress difficulty, cause leaking or cylinder-head distortion.The spill valve plate has generally adopted powdered metallurgical material in addition, and the variation of its density also influences the valve port Grinding Quality easily.So spill valve plate peace face valve plate is compared, the rate that rolls off the production line of the valve port tightness after its processing is higher, is difficult to basic the improvement.Simultaneously, in the prior art, particularly on the female valve group of high-efficient compressor product, exhaust valve plate designs very softly because consider the reason of exhaust efficiency, opens easilier when benefit is work, to the also easier applying sealing of exhaust valve port.But cross softly, might bring the valve block chatter in when work, simultaneously, the valve block Lift also may be very big, and the reliability of valve block also will reduce.
