如附表所列H41F-25C.25中的前2数字25,表示阀体的工作压力为2500kPa,后2个数字25,则表示阀体的通道直径为25mm。其他型号以此类推。表中所列15型、20型和25型3种型号阀体合用一副夹具。32型、40型和50型3种型号合用另一副夹具。加工时,必须按照3外型号中最大一种阀体尺寸设计夹具,当车加工其它两种小型号阀体横孔时,只需在小型号阀体一端法兰上,装上一专用衬垫,即可车加工该阀体的横孔。 As shown in the table, the first two digits of H41F-25C.25, 25, indicate that the working pressure of the valve body is 2500kPa and the last two digits of 25 indicate that the diameter of the valve body passageway is 25mm. Other models and so on. Table listed in the 15, 20 and 25 models of three types of valve body with a pair of clamps. 32 models, 40 models and 50 models with the other three models of the fixture. When machining, the fixture must be designed according to the largest one of the 3 outer models. When machining two other small-size valve body cross-holes, only one small flange on the valve body should be equipped with a special gasket , You can car machining horizontal hole of the valve body.
