H44H、H44Y 型旋启式钢制止回阀
价格:1.00
【产品用途】H44H、H44Y型旋启式钢制止回阀适用于压力1.6~25MPa工作温度-29~+550℃的石油、化工、制药、化肥、电力行业等各种工况的管路上,适用介质为水、油品、蒸汽、酸性介质等。【产品特点】H44H、H44Y型旋启式钢制止回阀是靠管路中介质本身的流动产生的力而自动开启和关闭的,属于一种自动阀门。止回阀用于管路系统,其主要作用是防止介质倒流、防止泵及其驱动电机机反转,以及容器内介质的泄放。止回阀还可用于给其中的压力可能升至超过主系统压力的辅助系统提供补给的管路上。【性能参数】型号H44H-16C~250H44W-16P~250工作压力(MPa)1.6~25适用温度(℃)≤425≤550适用介质水、蒸汽、油品弱腐蚀性介质材料阀体、阀盖、阀瓣碳素钢铬镍钛不锈钢密封面碳钢堆焊铁基合金本体密封主要外形和连接尺寸公称通径DN主要外形尺寸和连接尺寸LDD1D2bZ-dHH44H-16CH44W-16CH44W-16PH44W-16RH44W-16I251601158565164-141003218013510078164-181054020014510085164-1811550230160125100164-1813565290180145120184-1814280310195160135208-18165100350215180155208-18180125400245210185228-18210150480280240210248-232332005003352952652612-233042505504053553203012-253483006504604103753012-253903507505204704353416-254304008505805254853616-30468H44H-25H44W-25H44W-25PH44W-25RH44W-25I251601158565164-141003218013510078164-181054020014511085164-1811550230160125100204-1816065290180145120228-1817580310195160135228-18185100350230190160248-23220125400270220188288-25248150480300250218308-252762005503603102783412-253502506504253703323612-304103007504854303904016-304303508505504904484416-345184009506105505054816-34560声明:本文中所有文字、数据均只适用于参考,H44H、H44Y型PN16~PN250旋启式钢制止回阀性能参数、结构尺寸参数、价格等详情,请联系我们)
