Novel anti-backflow nodular cast iron well lid
The invention belongs to the technical field of well lids, and particularly relates to a novel anti-backflow nodular cast iron well lid. The anti-backflow well lid comprises a well lid body and an anti-backflow assembly additionally arranged on the lower side of the well lid body, and the anti-backflow assembly is mainly composed of an outer ring, a first partition plate, a second partition plate, a movable pipe, an upper annular end plate, a lower annular end plate and a spring. The movable pipe and the upper annular end plate are pushed to move upwards, so that the upper end opening of the upper annular end plate is shielded and sealed by the well lid body, sewage cannot be discharged outwards from the water guide through holes, backward flowing and backflow are effectively prevented, and dredging management of well lids at all positions in a road is facilitated. In addition, the spring cannot be stressed all the time and is not prone to failure, and when the movable pipe cannot overcome sliding resistance smoothly and returns to the original position due to local spring failure, the overall drainage capacity of the well lid cannot be greatly influenced.
本发明属于井盖技术领域，具体涉及一种新型防倒灌回流球墨铸铁井盖。本发明包括井盖本体和加装在其下侧的防倒灌回流组件，防倒灌回流组件主要由外环、第一隔板、第二隔板、活动管、上环形端板、下环形端板和弹簧构成，当下水道中的污水发生倒灌时，污水上涌至与下环形端板接触，推动活动管及上环形端板向上位移，使上环形端板的上端口被井盖本体遮挡密封，从而使污水无法从导水通孔向外排出，有效防止了倒灌回流的发生，方便于道路中各处井盖的疏通管理。另外，弹簧不会始终受力，不易失效，当局部的弹簧故障使得活动管不能顺利克服滑动阻力而回复原位时，也不会对井盖整体的排水能力造成加大的影响。
