在液压元件的设计中,由于油路沟通的需要,往往要在工件上设置一定的工艺孔,工艺孔用工艺堵堵住.常用的方法是将孔口加工成锥螺纹或直螺纹,用螺塞拧入工艺口,并用聚四氟乙稀生料带、密封胶或O 形密封圈密封,其工艺复杂。这种工艺堵的优点是可拆卸,便于维修。但大部分工艺孔在维修中不需要拆卸。这里介绍一种简便的不可拆卸式工艺球堵。 In the design of hydraulic components, due to the need of oil communication, often a certain process hole is set on the workpiece, and the process hole is blocked by a process plugging process. The commonly used method is to process the hole into a tapered thread or a straight thread, Corkscrew into the process mouth, and with Teflon tape, sealant or O-ring seal, the process is complex. The advantage of this process plug is removable, easy to repair. However, most of the holes in the process of maintenance do not need to disassemble. Here is a simple non-removable technology ball plug.
