Processing technology of valve gate and valve cover formed through thermosetting

The invention discloses a processing technology for a valve gate and a valve cover formed through thermosetting, a grinding disc is used for grinding a sliding contact plane of the valve gate and the valve cover, and in the grinding process, cooling liquid is used for cooling the grinding disc and the valve gate or the valve cover; the method is characterized in that in the continuous grinding time period of the grinding process, when the grinding disc acts on the sliding contact plane of the valve gate or the valve deck, the pressure applied by the grinding disc ranges from 0.1 Mpa to 0.3 Mpa, and the grinding time ranges from 2 minutes to 8 minutes. The grinding device has the advantages that the pressure applied to the valve grid and the valve cover to be ground by the grinding disc is used for regulation and control, and the grinding time is controlled, so that the grinding surface has consistent surface roughness, and consistent and standard grinding quality is obtained. 本发明公开了热固成型的阀栅阀盖加工工艺，利用研磨盘来对阀栅与阀盖滑
