我厂自1978年初安装了一台Z145A造型机。该机采用一个按压阀操纵造型过程中的全部五个工序,与用几个操作阀分别控制各个造型工序的造型机相比,具有气阀少、结构紧凑、操作方便等优点。但这种造型机由于分配阀易发生故障,维修频繁,经常影响生产。该机分配阀的结构见图1。阀瓣在压缩空气的作用下紧压在配气盘上,转动不灵活,有
I plant since early 1978 to install a Z145A molding machine. The machine adopts a pressing valve to manipulate all the five processes in the modeling process. Compared with a molding machine that controls each molding process by several operation valves, the machine has the advantages of less air valve, compact structure and convenient operation. However, this molding machine due to the distribution valve prone to failure, frequent maintenance, often affect the production. The machine distribution valve structure shown in Figure 1. Valve under the action of compressed air squeezed in the gas distribution plate, the rotation is not flexible, there
