操作原理和结构说明
手轮顺时针方向转时,阀杆向下移动,阀瓣下降使密封面密合,将通路切断.逆转时则开启,阀杆提到zui高点上密封起作用。
J41N液化气截止阀增加了一个上密封.在阀门开启状态时,与填料一起两层密封作用,并对填料有一定的保护作用
采用尼龙制品作密封面,填料为软成形填料,上密封也为软材质,密封性能较好.铸钢产品型号：J41N-16C、J41N-25C、J41N-32C、J41N-40C、J41N-64C、J41N-100C、J41N-150C、J41N-200C 内密封焊接系列：J41NY-16C、J41NY-25C、J41NY-32C、J41NY-40C、J41NY-64C、J41NY-100C、J41NY-150C、J41NY-200C. 不锈钢型号：J41N-16P、J41N-25P、J41N-32P、J41N-40P、J41N-64P、J41N-100P、J41N-200P。 316不锈钢型号：J41NY-16R、J41NY-25R、J41NY-32R、J41NY-40R、J41NY-64R、J41NY-100R、J41NY-200R.
