Municipal drainage pipeline flow limiting and backflow preventing integrated device
The invention discloses a municipal drainage pipeline flow limiting and backflow preventing integrated device which is characterized in that a fixed arc-shaped baffle (2) and a movable arc-shaped baffle (3) with the same diameter are arranged in a stainless steel shell (1), and the fixed arc-shaped baffle (2) and the movable arc-shaped baffle (3) are clamped in the stainless steel shell (1); the movable arc-shaped baffle (3) is located above the fixed arc-shaped baffle (2), one end of the movable arc-shaped baffle (3) is connected with a fixed pulley (8) fixed to the upper surface wall of the stainless steel shell (1) through a connecting rope (7), and the defects that in the prior art, a newly-built catch basin needs to be dismantled, the work amount is large, the construction period is long, and the construction cost is high are overcome. The drainage pipe network has the advantages of being compact in structure, convenient to install and low in manufacturing cost.
本发明公布了一种市政排水管道限流和防倒灌集成装置，所述的不锈钢外壳(1)内部设置有直径相同的固定弧形挡板(2)和移动弧形挡板(3)，所述的固定弧形挡板(2)和移动弧形挡板(3)卡在所述的不锈钢外壳(1)内，所述的移动弧形挡板(3)位于所述的固定弧形挡板(2)上方，所述的移动弧形挡板(3)的一端通过连接绳(7)与固定在所述的不锈钢外壳(1)上表壁的定滑轮(8)连接，他克服了现有技术中需要拆除新建截流井，工程量较大，且工期较长，施工期间影响排水管网运行的缺点，具有结构紧凑，安装方便，造价低廉的优点。
