富山对夹式金属硬密封蝶阀用途及特点：本蝶阀采用的是三维偏心原理设计，使密封面的空间运动轨迹达到理想化，密封面相互之间无磨擦、无干涉，加之密封材料选择得当，从而使蝶阀的密封性、耐腐蚀性、耐高温性和耐磨性等得到了可靠的保证。其主要特点如下：1、操作力矩小，操作方便，省力灵巧；2、三维偏心结构，使蝶板越关越紧，其密封性能可靠，达到零泄漏；3、耐高压、耐腐蚀、耐磨损、使用寿命长等。主要零件材料：零件名称材料阀体铸铁、不锈钢、铬钼钢、合金钢蝶板铸钢、合金钢、不锈钢、铬钼钢密封圈不锈钢与耐高温石棉板组合成多层次阀杆2Cr13、1Cr13不锈钢、铬钼钢填料柔性石墨D3（6、9）73H-6～10（C、P、R、V）系列连接尺寸：公称通径DN外形尺寸连接尺寸LHD373HD673HD973HPN0.6MPaPN1.0MPaH1A1B1H2A2B2H3A3B3D1z-dD1z-d5043112350180200625245725302502551104-141254-186546115370180200625245725502502551304-141454-188049120380180200645245725652502551504-141608-1810056138420180200675355926002502551704-181808-1812564164460180200715355926402502552008-182108-1815070175555270280800355927053003152258-182408-22200712086052702808502501707753003152808-182958-222507624368027028092525017094530031533512-1835012-22300832838003804201035450220107030031539512-2240012-22350923108353804201070450220114030031544512-2246016-224001023409154504701190450220121030031549516-2251516-264501143809604804901250650280133557571455016-2256520-2650012741010204804901295650280141557571460020-2262020-2660015447012254804901455850380160565681070520-2272520-3070016555013556406601585850380184465681081020-2684024-30800190640147064066017001250380204065681092024-3095024-339002037101545750860186512503802255785863102024-30105028-3010002167701795850900201512503802380785863112028-30116028-361200254890196585090012503802640785863134032-33138032-39D3（6、9）73H-16～25（C、P、R、V）系列连接尺寸：公称通径DN外形尺寸连接尺寸LHD373HD673HD973HPN1.6MPaPN2.5MPaH1A1B1H2A2B2H3A3B3D1z-dD1z-d5043112350180200625245725302502551254-181254-186546115370180200625245725502502551454-181458-188049120380180200645245725652502551608-181608-1810056138420180200675355926002502551808-181908-2212564164460180200715355926402502552108-182208-2615070175555270280800355927053003152408-222508-262007120860527028085025017077530031529512-2231012-262507624368027028092525017094530031535512-2637012-30300832838253804201035450220107030031541012-2643016-30350923109003804201070450220114030031547016-2649016-334001023409804504701190450220121030031552516-3055016-3645011438010304804901250650280133557571458520-3060020-3650012741011054804901295650280141557571465020-3366020-3660015447013104804901455850380160565681077020-3677020-3970016555014356406601585850380184465681084024-3687524-42800190640160564066017001250380204065681095024-3999024-489002037101745750860186512503802255785863105028-39109*028-4810002167701885850900201512503802380785863117028-42121028-561200254890210585090012503802640785863139032-48142032-56D3（6、9）73H-40（C、P、R、V）系列连接尺寸：公称通径DN外形尺寸连接尺寸LHD373HD673HD973HPN4.0MPaH1A1B1H2A2B2H3A3B3D1z-d5043112350180200625245725302502551254-186546115370180200625245725502502551458-188049120380180200645245725652502551608-1810056138420180200675355926002502551908-2212564164460180200715355926402502552208-2615070175555270280800355927053003152508-282007120860527028085025017077530031532012-302507624368027028092525017094530031538512-33300832838253804201035450220107030031545016-33350923109003804201070450220114030031551016-364001023409804504701190450220121030031558516-3945011438010304804901250650280133557571461020-39500127410110548049012956502801415575714670)
