铸铁闸阀安装浇注砼前，调整闸门与闸框偏心与间隙，锁紧锲块装置，已达到良好的止水效果。闸门的迎水面一定要按设计要求安装否则因板面受力方向不对，引起板面断裂，偶反向受压时一定要在订货时说明，防止发生重大事故。在订货时要提供空口尺寸，水头，提高度和结构形式，闸板面一般为正向（迎水面）受压，如需反向受压，订货时蠕动泵 保定建筑设计 保定网站建设 保定网站制作 保定网络公司 保定办公家具 保定轻钢别墅 需说明，止水一般是后止水（背水面），需前止水时，订货时应说明，使用时必须按操作规程操作。铸铁闸阀使用时应经常检查闸门板与闸槽是否卡涩，及时将卡涩物清楚，保证位置置中，使设备正常运行。
The eccentricity and clearance between gate and gate frame are adjusted and the tine block device is locked before the cast iron gate valve is installed to pour concrete, which has achieved good water stop effect. The front face of the gate must be installed according to the design requirements, otherwise, the plate surface will be broken due to the wrong direction of force acting on the plate surface. Sometimes, when the reverse pressure is applied, it must be explained at the time of ordering, so as to prevent serious accidents. When ordering, it is necessary to provide the size, head, height and structure of the empty port. The gate surface is generally pressurized in the positive direction (upstream surface). If reverse pressure is needed, it should be explained when ordering. The water stop is generally back water (backwater surface). When ordering before water stop, it should be stated when ordering, and the operation rules must be followed when using. Cast iron gate valves should be used to check whether the gate plate and groove are jammed, clear the jammed material in time, ensure the location in order to ensure the normal operation of the equipment.
