Nodular cast iron well lid
The invention relates to the field of municipal facilities, in particular to a nodular cast iron well lid which comprises a well ring, a well lid body and a reverse gushing prevention mechanism, the reverse gushing prevention mechanism is arranged on the lower surface of the well lid body and comprises an abutting ring, a bottom frame, a floating ball and a water passing plate, drainage grooves are formed in the center of the well lid body in an array mode, and the abutting ring is fixedly installed in the center of the lower surface of the well lid body; the bottom frame is fixedly installed at the lower end of the abutting ring, the floating ball is movably arranged in the bottom frame, the water passing plate is fixedly installed at the lower end of the bottom frame, and according to the design, normal drainage of rainwater is met, and meanwhile sewage and rainwater in a drainage pipeline can be effectively prevented from flowing back through the well lid; the floating ball ascends under the buoyancy action of backflow sewage and rainwater and abuts against the abutting ring to seal the drainage groove, so that backflow of the sewage and the rainwater is avoided, further deterioration of the road environment caused by the backflow is avoided, and the negative influence of the backflow of the sewage on surrounding residents and pedestrians is effectively reduced.
本发明涉及市政设施领域，尤其涉及一种球墨铸铁井盖,包括井圈、井盖及防反涌机构，防反涌机构设置在井盖下表面，防反涌机构包括抵触圈、底架、浮动球、通水板，井盖中心阵列开设有排水槽，抵触圈固定安装在井盖下表面中心，底架固定安装在抵触圈下端，浮动球活动设置在底架内，通水板固定安装在底架下端，该设计在满足雨水正常排泄的同时，可有效阻止排水管道内的污水、雨水经井盖反流，当污水、雨水反流时，浮动球受反流的污水及雨水浮力作用上升与抵触圈抵触封闭排水槽，从而实现避免污水及雨水的反流，避免因反流导致道路环境进一步恶化，有效减少污水反流给周边居民、行人带来的消极影响。
