德國GSR氣動閥門系統各部分功能和用途

公稱壓(ya)力(Nominal pressure)表示符(fu)號PN，在一定溫度(du)下應(ying)用時(shi)允許的(de)zui大工(gong)(gong)作(zuo)(zuo)(zuo)壓(ya)力。對碳鋼(gang)閥(fa)體(ti)的(de)控制(zhi)閥(fa)，指(zhi)200℃以下應(ying)用時(shi)允許的(de)zui大工(gong)(gong)作(zuo)(zuo)(zuo)壓(ya)力；對鑄鐵(tie)閥(fa)體(ti)，指(zhi)120℃以下應(ying)用時(shi)允許的(de)zui大工(gong)(gong)作(zuo)(zuo)(zuo)壓(ya)力；對不(bu)銹鋼(gang)閥(fa)體(ti)的(de)控制(zhi)閥(fa)，指(zhi)250℃以下應(ying)用時(shi)允許的(de)zui大工(gong)(gong)作(zuo)(zuo)(zuo)壓(ya)力。當工(gong)(gong)作(zuo)(zuo)(zuo)溫度(du)升高(gao)時(shi)，閥(fa)體(ti)的(de)耐壓(ya)會降低。

例如(ru)，公稱壓(ya)(ya)(ya)力(li)(li)(li)(li)(li)為(wei)6.4MPa（PN64）的(de)(de)碳(tan)鋼控制(zhi)(zhi)閥，用(yong)于300℃時的(de)(de)耐壓(ya)(ya)(ya)為(wei)5.2MPa，用(yong)400℃時的(de)(de)耐壓(ya)(ya)(ya)為(wei)4.1MPa，用(yong)于450℃時的(de)(de)耐壓(ya)(ya)(ya)為(wei)2.9MPa。因此，控制(zhi)(zhi)閥公稱壓(ya)(ya)(ya)力(li)(li)(li)(li)(li)的(de)(de)確定不(bu)僅(jin)(jin)要根(gen)據(ju)zui高工作(zuo)壓(ya)(ya)(ya)力(li)(li)(li)(li)(li)，還需根(gen)據(ju)zui高工作(zuo)溫度和材質特性，而不(bu)僅(jin)(jin)僅(jin)(jin)只(zhi)需滿足公稱壓(ya)(ya)(ya)力(li)(li)(li)(li)(li)大(da)于工作(zuo)壓(ya)(ya)(ya)力(li)(li)(li)(li)(li)。氣(qi)動(dong)控制(zhi)(zhi)閥是指在氣(qi)動(dong)系統(tong)中(zhong)控制(zhi)(zhi)氣(qi)流的(de)(de)壓(ya)(ya)(ya)力(li)(li)(li)(li)(li)、流量和流動(dong)方向，并保(bao)證(zheng)氣(qi)動(dong)執(zhi)行元(yuan)件(jian)(jian)或機構(gou)正常工作(zuo)的(de)(de)各類氣(qi)動(dong)元(yuan)件(jian)(jian)。
