Abstract

The invention discloses a sealing inspection well socket and relates to the field of sealing connection devices of plastic inspection well sockets. The sealing inspection well socket comprises a socket body. The socket body comprises a fixed socket body and a removable socket body. The removable socket body is composed of an outer sleeve, an inner sleeve and an annular groove formed between the inner sleeve and the outer sleeve. The outer wall of the fixed socket body is provided with external threads. The inner wall of the outer sleeve is provided with internal threads corresponding to the external threads. The inner diameter of the fixed socket body is larger than the outer diameter of the inner sleeve. The sealing inspection well socket can compress a sealing ring between a pipe and the socket through the threads to reduce the gap between the pipe and the socket. The sealing inspection well socket is good in sealing performance and easy to operate.

Description

technical field [0001] The invention relates to the field of sealing connection devices for plastic inspection well sockets, in particular to a sealing inspection well socket. Background technique [0002] Inspection wells are vertical shafts built at regular intervals for rainwater and sewage discharge pipes to connect pipelines with different diameters, directions and heights. They are mainly used by maintenance workers to regularly inspect and dredge pipes, It is one of the underground infrastructures of urban roads to prevent sludge and foreign matter and prevent pipeline blockage. [0003] Due to the light weight and corrosion resistance of plastic drainage pipes and plastic inspection wells, the rigidity of pipe rings can be designed according to needs, the joints are well sealed, and there is no leakage, which can effectively prevent groundwater pollution, and the construction speed, hydraulic conditions, and cost performance are excellent. It is used in cement drain...
