为可靠。但是焊接连接的阀门拆卸和重新安装都比较困难，所以它的使用限于通常能长期可靠地运行，或使用条件荷刻、温度较高的场合。如火力发电站、核能工程、乙烯工程的管道上。 

　　公称通径在50mm以下的焊接阀门通常具有焊接插口来承接荷平面端的管道。由于承插焊接在插口与管道间形成缝隙，因而有可能使缝隙受到某些介质的腐蚀，同时管道的振动会使连接部位疲劳，因此承插焊接的使用受到一定的限制。 

　　在公称直径较大，使用条件荷刻，温度较高的场合，阀体常采用坡口对焊接，同时，对焊接缝有原格要求，必须选用技术过4WE6D6X/OFEG24N9K4 4WE6JA6X/EG24N9K4 4WE6J7X/HG24N9K4 4WE6J6X/EG24N9K4） 4WE6HA6X/EG24N9K4 4WE6Y6X/EG24N9K4 4WE10J3X/CG24N9K4 4WE6J6X/EG24N9K4 4WE6D6X/EG24N9K4 4WE6C6X/EG24N9K4） 4WE6E6X/EG24N9K4 4WE6R73-6X/EG24N9K4/A12 4WE6D53/OFAW110N-50N24 4WMM10JB31/F 4WMM10J31/F 4WE10D3X/OFCG24N9K4 4WE10D3X/CG24N9K4 4WE10EA3X/CG24N9K4 4WE10EB3X/CG24N9K4 4WE10Y3X/CG24N9K4 4WE10E3X/CG24N9K4 4WE10J3X/CG24N9K4 4WE10L3X/CG24N9K4 4WE10U3X/CG24N9K4 4WE10C3X/CG24N9K4 4WE10G3X/CG24N9K4 4WE10H3X/CG24N9K4 4WE10D3X/CW230N9K4 4WE10E3X/CW230N9K4 4WE10J3X/CW230N9K4 4WE10G3X/CW230N9K4 4WE10H3X/CW230N9K4 4WE10D3X/CW110N9K4（改线圈） 4WE10H3X/CW110N9K4（改线圈） 4WREE10E50-2X/G24K31/A1V 4WREE10E75-2X/G24K31/A1V 4WEH16J7X/6EG24 4WEH16D7X/6EG24 4WEH16EA7X/6EG24 4WEH16C7X/6HG24N9K4 4WEH16EA7X/6HG24N9K4 4WEH16Y31-7X/6HG24N9K4 4WEH16D7X/6HG24N9K4 4WEH16E/6HG24N9ETK4 4WEH16J/6HG24N9ETK4 4WEH16L/6HG24N9ETK4 4WEH16U/6HG24N9ETK4 4WEH16D7X/6EG24N9ETK4 4WEH16EA7X/6EG24N9ETK4 4WEH16EB7X/6EG24N9ETK4 4WEH16E7X/6EG24N9ETK4 4WEH16J7X/6EG24N9ETK4 4WEH16EB7X/6EG24EG24EK31/A1D3M 4WRKE16E-125L3X/6EG24EK31/A1D3M 4WRKE16E-200L3X/6EG24EK31/A1D3M 4WRKE16E-125L3X/6EG24EK31/A1D3M 4WRKE16E-200L3X/6EG24EK31/A1D3M 4WEH22Y31-7X/6HG24N9ETK4 4WEH22E/6HG24N9ETK4 4WEH22J/6HG24N9ETK4 4WEH22U/6HG24N9ETK4 4WEH22L/6HG24N9ETK4 4WEH22E7X/6AG24N9ETK4 4WEH22D7X/6AG24N9ETK4 4WEH22J7X/6AG24N9ETK4 4WEH22E7X/6EG24N9ETK4 4WEH22D7X/6EG24N9ETK4 4WEH22J7X/6EG24N9ETK4 4WEH22E7X/6EW230N9ETK4 4WEH22D7X/6EW230N9ETK4 4WEH22J7X/6EW230N9ETK4 4WRKE25E350L3X/6EG24EK31/A1D3M 4WRKE25E350L3X/6EG24EK31/A1D3M 4WRKE25E500L3XH/6EG24EK31/A1D3M 4WRKE25E500L3XH/6 4WEH16E7X/6EG24 VT-VSPA2-1-1X/T1 DR6DP2-53/210YM (R900466591) VT-VSPA2-1-1X/T5 DR6DP3-53/210YM (R900481033) DBAW25AH2－21/350-6EG24N9K4 (R901027751) VT11030-1X A4VS0180DR/30RPPB13N00(SN:30517766)特价力士乐阀门大量现货叠加式单向阀 Z2FS6-2-4X/2QV Z2FS10-5-3X Z1S6C1-3X Z1S6PO5-4V 编辑编辑编辑噪声源3、减小液压冲击的措施 Z2S6-1-6X Z2S6-2-6X Z2S6A-2-6X Z2S6B-1-6 Z2S10-1-3X Z2S10-2-3X Z2FS10-5-3X/ Z2FS6-2-4X/2QV Z2S10-2-3X Z2S6-2-6X Z2S10-1-3X (R900407394) ZDB6VB2-4X/200V ZDB6VP2-4X/200V ZDB6VP2-4X/315?
