一、活塞式泄压阀概述：活塞式泄压阀本产品由主阀和针型调节阀、导阀、球阀及接管系统组成，主阀阀体采用全通道、直流式、流线型设计，并采用膜片式或活塞式两类结构。本产品利用设定调压导阀弹簧压力和调节针型阀开度设定出口压力，并通过接管系统和控制室的反馈作用来稳定出口压力。活塞式泄压阀产品利用针型调节阀、导阀进行水压自力控制，不需要附加其它装置和能源，维护保养简便，受进口压力和流量影响小，压力控制准确度高，减压稳压可靠。二、活塞式泄压阀主要技术参数：公称压(Mpa)壳体试验压力(MPa)密封试验压力(MPa)调压范围(MPa)适用介质介质温度(℃)1.01.51.10-1.0水0-801.62.41.760-1.62.53.752.750-2.5二、活塞式泄压阀主要外形尺寸：DNLHD(mm)D1(mm)B(mm)mmmmPN1.0PN1.6PN2.5PN1.0PN1.6PN2.5Mpa1.0Mpa1.6Mpa2.5402033001651651651251251254-184-184-18502033001651651651251251254-184-184-18652163371851851851451451454-184-188-18802484672002002001601601608-188-188-181002835202202202351801801908-188-188-221253305802502502702102102208-188-188-221503566402852853002402402508-228-228-262004447783403403602952953108-2212-228-2625053388939540542535035537012-2212-2612-26300600101044546048540041043012-2212-2612-30350622103750552055546047049016-2216-2616-33400698126456558062051552555016-2616-3016-36450775129461564067056558560020-2620-3020-36500811132467071573062065066020-2620-3320-36600900160078084072577020-3020-36700980175089591084084024-3024-36800110019001015102595095024-3324-39900122021001115105028-331000132024001230116028-36)
