一、产品用途氧气专用截止阀YJ41W-16P、YJ41W-25P不锈钢截止阀采用材质优良的硅黄铜或不锈钢铸造而成，具有机械强度高，耐磨损、安全性好等优点。使用在氧气管路上，具有***佳的防爆阻燃性能，消除了氧气管路上的不安全因素。***截止阀采用弹性V形聚四氟乙烯或丁晴橡胶作为动密封填料，由填料盖/不锈***簧提供初始密封，填料密封性能随介质压力上升而增强，既具有密封性能，无需人工维护。区别于其它阀门，YJ41W-16P、YJ41W-25P不锈钢截止阀适用于大多数高中压燃气输送管线、混气站、储配站等场合。二、产品特点1、防燃阻火：主要部件的材质为铜合金，属不可燃材料，即使与高速气流中的固体粒子碰撞也不会产生火花。因此，本阀具有***佳的防燃阻火性能。2、安全可靠：本阀带有防尘、防水、防油污装置，所有与氧气接触的阀件在组装前均经过严格脱脂和禁油措施，填料材质为聚四氟乙烯，可确保使用时安全可靠。三、用途原理氧气专用截止阀属于强制密封式阀门，所以在阀门关闭时，必须向阀瓣施加压力，以强制密封面不泄漏。氧气截止阀是氧气管网专用阀门的一种。使用于城市液化气***贮备站,氧气截止阀也使用于炼油厂,石油化工厂,石油化工厂的液化气系统,作为控制介质截流的启闭装置。四、氧气专用截止阀YJ41W-16P、YJ41W-25P不锈钢截止阀压力试验公称压力强度试验水密封试验上密封试验气密封试验2.53.82.82.80.64.06.04.44.4五、氧气专用截止阀YJ41W-16P、YJ41W-25P不锈钢截止阀主要零件材料及性能体盖阀杆阀瓣密封面垫片填料工作温度适用介质1Cr18Ni9Ti1Cr18Ni9Ti1Cr18Ni9Ti本体材质PTFEPTFE常温氧气ZCrZn16Si4六、氧气专用截止阀YJ41W-16P、YJ41W-25P不锈钢截止阀主要尺寸1.6MPaDNLDD1D2bn-ΦdHDo凸面法兰RFJY41W-16PJY41W-16TJY41Y-16PJY41Y-16T251601158565144-Φ143051603218013510078164-Φ183161604020014511085164-Φ1832818050230160125100164-Φ1835620065290180145125184-Φ1838928080310195160135208-Φ18400280100350215180155208-Φ18460320125400245210185228-Φ18528320150480280240210248-Φ236684502006003352952652626-Φ237955002506504053553203030-Φ259105603007504604103753030-Φ2512006403508505204704353434-Φ2512007204009505805254853636-Φ301560800氧气专用截止阀YJ41W-16P、YJ41W-25P不锈钢截止阀PN2.5MPa-4.0Mpa规格主要尺寸2.5MPaDNLDD1D2bn-ΦdHDO251601158565164-Φ14305160凸面法兰RFJY41W-25PJY41W-16THY41Y-16PJY41Y-16T3218013510078184-Φ183161604020014511085184-Φ1832818050230160125100204-Φ1835620065290180145120228-Φ1838928080310195160135228-Φ18400280100350230190160248-Φ23460320125400270220188288-Φ25538320150480300250218308-Φ256684502006003603102783412-Φ257955002506504253703323612-Φ309105603007504854303904016-Φ3012006403508505504904484416-Φ3412907204009506105505054816-Φ3415608004.0MPa251601158565164-Φ14305160凸面法兰RFJY41W-40PJY41W-40THY41Y-40PJY41Y-40T3218013510078184-Φ183161604020014511085184-Φ1832818050230160125100204-Φ1835620065290180145120228-Φ1838928080310195160135228-Φ18400280100350230190160248-Φ23460320125400270220188288-Φ25538320150480300250218308-Φ256684502006003753202823812-Φ307955002506504453853454212-Φ349105603007505104504084616-Φ3412006403508505705104655216-Φ3412907204009506555855355816-Φ411560800)
