Anti-falling and anti-backflow well lid
The invention discloses an anti-backflow and anti-falling well lid and belongs to the technical field of municipal engineering construction, the anti-backflow and anti-falling well lid comprises a well lid body, an anti-falling hopper and an anti-backflow device, the anti-backflow device is arranged on a lower well ring, an upper well ring is arranged on the upper portion of the anti-backflow device, the well lid body is arranged on the upper portion of the upper well ring, and the anti-falling hopper is arranged in the well lid body. The anti-backflow device comprises a seat ring, a bending assembly is arranged on one side in the seat ring, the bending assembly is connected with a valve rod, a valve clack is arranged on the upper portion of the valve rod, the valve rod is fixedly connected with the valve clack through a fastening device, and a pressure relief hole is formed in the middle of the valve clack. The anti-falling hopper can prevent garbage from blocking the tube well at ordinary times, people can conveniently clean sundries by opening the well lid, the anti-falling function can be achieved after the well lid is lost, water flow can be prevented from flowing backwards through the anti-backflow device, and the pressure relief effect can be achieved according to needs.
本发明公开了一种防倒灌、防坠落井盖，属于市政工程施工技术领域，包括：井盖、防坠斗、防倒灌装置，所述防倒灌装置设置在下部井圈上，所述防倒灌装置上部设置上部井圈，所述上部井圈上部设置井盖，所述井盖内部设置所述防坠斗。所述防倒灌装置包括座环圈，所述座环圈内部一侧设置有弯曲组件，所述弯曲组件连接设置有阀杆，所述阀杆上部设置有阀瓣，所述阀杆与所述阀瓣通过紧固装置固定连接，所述阀瓣中部设置有泄压孔。防坠斗平时可防垃圾堵塞管井，打开井盖即可方便人员清理杂物，也可起到井盖丢失后防坠落的功能，通过防倒灌装置即可防止水流倒灌，又可根据需要起到泄压的作用。
