节能型侧开式铸铁拍门是保证泵站安全运行的重要设备,在泵站中其作用是断流和防止停机时水倒流,主要用于:防洪排涝、农田灌溉、城市给排水和跨流域调水,以及各大型工矿企业的供水和配水等。

节能型侧开式铸铁拍门由门板、门铰、门座和密封件等组成。门板通过门铰安装在门座上,根据国内泵站的应用情况,铸铁拍门的门形圆形和矩形两种。一般出水管口径小于、等于2m的(即口径1.6的泵)用圆形铸铁拍门,大于该口径的用矩形铸铁拍门。


节能拍门主要技术特点


1、无需任何启闭装置,能自动关闭。节能型侧开式铸铁拍门与悬挂式铸铁拍门相比最显著的特点是:将阀体铰轴竖向布置,并设计了一个最佳倾斜角度,利用门重分力作闭门的动力,不管大、中、小通径铸铁拍门,均无需任何启闭装置。

2、 安 全稳定,节能高效。节能型侧开式铸铁拍门运行时阻力小,开启角度大,闭门时撞击力小,消除了水锤和出水时产生的漩涡;无需、手、电、气、液控制,不要人工 操作,节省大量人力物力,提高泵站运行可靠性和装置效率,降低运行维护成本,降低泵站耗能。

Energy-saving side-open cast iron circular clapper door is an important equipment to ensure the safe operation of pumping stations. Its role in pumping stations is to cut off the flow and prevent water backflow during shutdown. It is mainly used for flood control and drainage, farmland irrigation, urban water supply and drainage and inter-basin water transfer, as well as water supply and distribution of large-scale industrial and mining enterprises. The energy-saving side open cast iron flap gate is composed of door panels, door hinge, door seat and seals. The door plate is mounted on the door base through the door hinges. According to the application of domestic pumping stations, there are two kinds of gate-shaped circular and rectangular iron flap doors. Generally, the outlet pipe diameter is less than or equal to 2m (that is, the diameter of 1.6 pump) with round cast iron clap door, larger than the diameter of the rectangular cast iron clap door. The main technical features of the energy-saving door are 1, no need for any hoist device, and it can be automatically closed. The most remarkable feature of the energy-saving side-open cast iron flap door is that the hinge shaft of the valve body is arranged vertically and an optimum angle of inclination is designed. The power of the door is used to close the door, and no opening or closing device is needed for large, medium or small diameter cast iron flap door. 2, safety and stability, energy saving and high efficiency. The energy-saving side-open cast iron flap door has the advantages of small resistance, large opening angle, small impact force when closing the door, eliminating the whirlpool produced by water hammer and water discharge, no need for manual operation, saving a lot of manpower and material resources, improving the operation reliability and equipment efficiency of pumping station, reducing the operation and maintenance costs. Reduce energy consumption of pumping stations.
