我厂空压站设置两台捷克产4DSK-450型空压机,该机的一级吸、排气阀采用带缓冲片的网状阀。阀片是几何形状相当复杂的网形阀片（如图1）。由于这种阀片精度要求较高,同时,中心尚有和阀片工作表面成10°角的六个弹性定位爪,故制造困难,加工工艺复杂。近几年我厂先后与许多专业生产厂联系,都没有能够解决这种阀片制造的质量问题。因国内订购不到符合技术要求的该种网形阀片,至使这两台空压机长期以来因阀片经常断裂而严
I plant air compressor station set two Czech 4DSK-450-type air compressor, the aircraft a suction, exhaust valve with a buffer piece mesh valve. The valve plate is a complex geometry of the mesh valve (Figure 1). Due to the high precision of the valve plate, at the same time, the center still has six elastic positioning claws at a 10 ° angle with the working surface of the valve plate, which makes the manufacture difficult and the processing technology is complicated. In recent years, our factory has contact with many professional manufacturers, have not been able to solve this quality problem of valve manufacturing. Due to domestic orders can not meet the technical requirements of the network-shaped valve, so that these two air compressor for a long time due to frequent rupture of the valve
