A41H弹簧微启封闭式安全阀安全阀是一种由进口静压开启的自动泄压防护装置，它是压力容器最为重要的安全附件之一，它的功能是：当容器内压力超过某一定值时，依靠介质自身的压力自动开启阀门，迅速排出一定数量的介质。当容器内的压力降到允许值时，阀又自动关闭，使容器内压力始终低于允许压力的上限，自动防止因超压而可能出现的事故，所以安全阀又被称为压力容器的最终保护装置。安全阀常见故障及原因【安全阀漏气】（1）阀芯与阀座接触面不严密；（2）阀芯与阀座接触面有脏物；（3）阀杆偏斜。【安全阀到规定压力时不开启】（1）阀芯与阀座粘住，可做手动排气试验排除；（2）弹簧式安全阀的弹簧调整压力过大，应重新调整；（3）杠杆式安全阀的重锤向后移动，应将重锤移到原来定压的位置上，用限动螺丝紧固。【安全阀不规定压力时开启】（1）弹簧式安全阀的弹簧调整压力不够、弹簧失效或弹力不足，应重调或重换安全阀；（2）杠杆式安全阀重锤向前移动，应将重锤移到原来定压的位置上，用限动螺丝紧固。A41H弹簧微启封闭式安全阀A41H弹簧微启封闭式安全阀适用于工作温度≤300℃的石油气、空气、水等介质的设备或管路上。A41Y-P/R型适用于工作温度≤200℃有腐蚀性介质的设备或管路上，作为超压保护装置。连接法兰标准按JB/T……94/系列1。■弹簧微启封闭式安全阀外形尺寸和连接尺寸型号公称通径doDKgg1bff1Z-?dDN’D1K1g2g’b1f’f1’Z1-?d1LL1≈HA41H-16CA41Y-16PA41Y-16RKA41Y-16CKA41Y-16P201510575-55162-4-14201057555-162-4-1410085276252011585-65162-4-14251158565-162-4-14100852763225140100-78182-4-183214010078-182-4-181151002854032150110-85183-4-184015011085-183-4-181201102925040165125-100203-4-1850165125100-203-4-181351203706550185145-120203-4-1865185145120-203-4-181401303758065200160-135203-8-1880200160135-203-8-1816013537310080220180-155223-8-18100220180155-223-8-18170160513125100250210-185223-8-18125250210185-223-8-18190190560150125285240-210243-8-23150285240210-243-8-23205195570200150340295-265263-12-23200340295265-263-12-23240230717250200405355-320303-12-26250405355320-303-12-26350320940300250460410-375304-12-26300460410375-304-12-26350320980A41H-25A41Y-25PA41Y-25RKA41Y-25KA41Y-25P201510575-55162-4-14201057555-162-4-1410085276252011585-65162-4-14251158565-162-4-14100852763225140100-78182-4-183214010078-182-4-181151002854032150110-85183-4-184015011085-183-4-181201102925040165125-100203-4-1850165125100-203-4-181351203706550185145-120223-8-1865185145120-203-4-181401303758065200160-135243-8-1880200160135-203-8-1816013537310080230190-160243-8-23100220180155-203-8-18170160513125100270220-188283-8-26125250210185-223-8-18190190560150125300250-218303-8-26150285240210-243-8-23205195570200150360310-278343-12-26200340295265-263-12-23240230717250200425370-332363-12-30250405355320-303-12-26350320940300250485430-390404-16-30300460410375-304-12-26350320980A41H-40A41Y-40PA41Y-40RKA41Y-40KA41Y-40P201510575515516244-14201057555-162-4-1410085276252011585586516244-14251158565-162-4-14100852763225140100667818244-183214010078-182-4-181151002854032150110768518344-184015011085-183-4-1812011029250401651258810020344-1850165125100-203-4-18135120370655018514511012022348-1865185145120-203-4-18140130375806520016012113522348-1880200160135-203-8-18160135373100802351901501602434.58-23100220180155-223-8-181701605131251002702201761882834.58-26125250210185-223-8-181901905601501253002502042183034.58-26150285240210-243-8-232051955702001503753202602823834.512-30200340295265-263-12-232402307172502004503853133454234.512-34250405355320-303-12-263503209403002505154503644084644.516-34300460410375-304-12-26350320980A41H-64A41Y-64A41Y-64PA41Y-64R201513090516820244-182010575555116244-14100952682520140100587822244-182511585655816244-14100952683225155110668224244-2332140100786618244-181151052794032170125769524344-2340150110857618344-1813511533050401801358810526344-23501651251008820344-18160125360655020516011013028348-236518514512011022348-18175160503806521517012114030348-238020016013512122348-18175160498100802502001501683234.58-261002351901601502434.58-231901805301501003452802042403834.58-341503002502182043034.58-26280260657,A41H-100A41Y-100A41Y-100PA41Y-100R201513090516822244-182010575555116244-14100952682520140100587824244-182511585655816244-14100952683225155110668224244-2332140100786618244-181151052794032170125769526344-2340150110857618344-1813511533050401951458811228344-26501651251008820344-18160125360655022017011013832348-266518514512011022348-18175160503806523018012114834348-268020016013512122348-18175160498100802652101501723834.58-301002351901601502434.58-231901805301501003552902042504634.512-341503002502182043034.58-26280260657NO零件名称A41H-16材料A41H-16P材料A41H-16R材料1法兰35/35CrMoA2Cr131Cr18Ni9Ti2阀座2Cr131Cr18Ni9Ti1Cr18Ni12Mo2Ti3阀体35/401Cr18Ni9Ti1Cr18Ni12Mo2Ti4阀瓣2Cr131Cr18Ni9Ti1Cr18Ni12Mo2Ti5导向套2Cr131Cr18Ni9Ti1Cr18Ni12Mo2Ti6弹簧50CrVA50CrVA包覆氟塑料50CrVA包覆氟塑料7阀杆2Cr131Cr18Ni9Ti1Cr18Ni12Mo2Ti8阀盖ZG230-4501Cr18Ni9Ti1Cr18Ni9Ti9调整螺杆452Cr132Cr1310阀帽ZG200-4001Cr18Ni9Ti1Cr18Ni9Ti阀座、阀瓣密封面堆焊Co基硬质合金尼威安全阀相关产品:A46F先导式安全阀A28H带手柄/弹簧全启式外螺纹安全阀A27H/带手柄弹簧微启式外螺纹安全阀NA42H、NA802Y型安全溢流阀A38Y/A37Y/A43Y弹簧双联式安全阀NWA72W真空负压安全阀GA41H、A51H型单杠杆安全阀GA44H双杠杆安全阀A48Y弹簧全启式安全阀A21F、A21H弹簧微启式外螺纹安全阀<)
