一、弹簧微启封闭式安全阀概述A41H型适用于工作温度≤300℃的***、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。当设备和管路内压力超过允许值时，阀门自动开启，继而全量排放；当压力降低到规定值时，阀门自动关闭，保证设备和管路安全运行。连接法兰标准按JB/T……94/系列。二、弹簧微启封闭式安全阀结构简述1、弹簧微启式安全阀具有结构简单、密封性能好、开启压力准确、排放能力大、回座压差小、调整方便等特点。2、喷嘴型阀座：阀座为位伐尔喷嘴型阀座，蒸汽流经阀座出口处时达到音速，排放系数大，阀座密封面堆焊钴铬钨硬质合金，耐磨抗冲蚀，寿命长。3、热弹性阀瓣：阀瓣设计为热弹性结构，利用其在介质压力下微小的变形，提高密封能力，克服安全阀在介质压力下临近整定压力时的前泄现象。阀瓣密封面采用***的激光淬火技术，提高了硬度、耐磨性、抗冲抗性。4、调节螺母：通过调整调节螺母，调整弹簧压缩量，使阀门能够很方便、很迅速地获得准确的整定压力。5、背压调整套：调整阀瓣背压的辅助机构，通过背压调整套调整，可获得合适的回座压差。上调时，使阀门背压降低。下调时，使阀门背压提高。三、弹簧微启封闭式安全阀安装说明1、安全阀必须垂直安装，并***好直接安装在容器或管道的接头上。接头内径应不小于安全阀的进口通径。2、安全阀的出口必须装设适当的膨胀节，以防止排放管的热膨胀给安全阀带来不应有的热应力。排放管内径应比阀门出口直径大，长度尽可能短，避免拐弯。排放管及膨胀节重量不应作用在安全阀上，应固定在建筑上。排放管的中心线与阀体的中心线间距离尽可能的短。对每台安全阀都应单独装设排放管。3、消声器的出口处要有足够的面积，防止产生背压影响阀门的排放能力。四、弹簧微启封闭式安全阀主要零部件材料NO零件名称A41H-C/KA41Y-C材料A41Y-P/KA41Y-P材料A41Y-R/KA41Y-R材料1阀体WCBZG1Cr18Ni9TiZG1Cr18Ni12Mo2Ti2阀座ZG2Cr13/1Cr18Ni9TiZG1Cr18Ni9TiZG1Cr18Ni12Mo2Ti3调节圈ZG2Cr13/1Cr18Ni9TiZG1Cr18Ni9TiZG1Cr18Ni12Mo2Ti4阀瓣2Cr13/1Cr18Ni9Ti1Cr18Ni9Ti1Cr18Ni12Mo2Ti5导向套ZG2Cr13/1Cr18Ni9TiZG1Cr18Ni9TiZG1Cr18Ni12Mo2Ti6阀盖ZG230-450ZG230-450ZG230-4507弹簧50CrVA50CrVA包覆氟塑料50CrVA包覆氟塑料8阀杆2Cr132Cr131Cr18Ni12Mo2Ti9调整螺杆452Cr132Cr1310保护罩ZG200-400ZG200-400ZG200-400密封面材料堆焊D507堆焊Co基硬质合金五、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-16P201510575551624-142010575551624-1410085276252011585651624-142511585651624-14100852763225140100781824-1832140100781824-181151002854032150110851834-1840150110851834-1812011029250401651251002034-18501651251002034-1813512037065501851451202034-18651851451202034-1814013037580652001601352038-18802001601352038-18160135373100802201801552238-181002201801552238-181701605131251002502101852238-181252502101852238-181901905601501252852402102438-231502852402102438-2320519557020015034029526526312-2320034029526526312-2324023071725020040535532030312-2625040535532030312-2635032094030025046041037530412-2630046041037530412-26350320980A41H-25A41Y-25PA41Y-25RKA41Y-25KA41Y-25P201510575551624-142010575551624-1410085276252011585651624-142511585651624-14100852763225140100781824-1832140100781824-181151002854032150110851834-1840150110851834-1812011029250401651251002034-18501651251002034-1813512037065501851451202238-18651851451202034-1814013037580652001601352438-18802001601352038-18160135373100802301901602438-231002201801552038-181701605131251002702201882838-261252502101852238-181901905601501253002502183038-261502852402102438-2320519557020015036031027834312-2620034029526526312-2324023071725020042537033236312-3025040535532030312-2635032094030025048543039040416-3030046041037530412-26350320980A41H-40A41Y-40PA41Y-40RKA41Y-40KA41Y-40P201510575515516244-142010575551624-1410085276252011585586516244-142511585651624-14100852763225140100667818244-1832140100781824-181151002854032150110768518344-1840150110851834-1812011029250401651258810020344-18501651251002034-18135120370655018514511012022348-18651851451202034-18140130375806520016012113522348-18802001601352038-18160135373100802351901501602434.58-231002201801552238-181701605131251002702201761882834.58-261252502101852238-181901905601501253002502042183034.58-261502852402102438-232051955702001503753202602823834.512-3020034029526526312-232402307172502004503853133454234.512-3425040535532030312-263503209403002505154503644084644.516-3430046041037530412-26350320980A41H-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-100R</a41h-100201513090516822244-182010575555116244-14100952682520140100587824244-182511585655816244-14100952683225155110668224244-2332140100786618244-181151052794032170125769526344-2340150110857618344-1813511533050401951458811228344-26501651251008820344-18160125360655022017011013832348-266518514512011022348-18175160503806523018012114834348-268020016013512122348-18175160498100802652101501723834.58-301002351901601502434.58-231901805301501003552902042504634.512-341503002502182043034.58-26280260657)
