Description

Conversion connecting piece for plastic inspection well seat

Technical Field

The utility model belongs to the technical field of municipal drainage pipelines, and particularly relates to a conversion connecting piece for a plastic inspection well seat.

Background

The traditional brick inspection well is built by using bricks, cement and the like, the construction period is long, the construction is greatly influenced by weather, the plastic inspection well is formed by fittings such as a well seat, a well shaft and a well cover, the fittings are prefabricated by production units, the plastic inspection well can be completed only by assembling when the traditional brick inspection well is used on site, the construction is quick and efficient, the plastic inspection well has good corrosion resistance, low inner wall roughness and good water conservancy property, and the traditional brick inspection well is a new product for replacing the traditional brick inspection well.

The plastic inspection well seat is a core accessory of the plastic inspection well, the upper part of the plastic inspection well seat is connected with a well shaft, and the lower part of the plastic inspection well seat is connected with each branch pipe. The well seat can be connected with various types of pipes, such as PE solid wall pipes, HDPE double-wall corrugated pipes, high-density polyethylene winding reinforced pipes and the like, when flat wall pipes or corrugated pipes are connected, rubber rings can be directly sleeved outside the pipes to directly connect the pipes in a socket manner, and the pipes enter branch pipe openings of the well seat, but if the branch pipes adopt special-shaped structure wall pipes such as the high-density polyethylene winding reinforced pipes, the special-shaped structure wall pipes cannot be directly sleeved with the rubber rings to directly connect the inspection well seat and the pipes by adopting conversion connecting pieces.

The existing conversion connecting piece is composed of a plastic injection molding sleeve and a rubber ring, the sleeve on the market is of a concentric reducing structure, the surface is smooth, the rubber ring is directly sleeved at the outer edges of two ends of the sleeve, one end of the rubber ring is inserted into a well seat supporting hole, the other end of the rubber ring is inserted into a pipe of a special-shaped structure wall pipe, and the well seat is connected with the pipe. However, in actual use, the rubber ring is found to run easily when the socket joint is carried out, so that the effect of connecting tightness is poor, sometimes the installation requirement can be met only by disassembling and adjusting the position of the rubber ring for multiple times, and certain influence is brought to the operation of installers and the construction period, even the water blocking performance of pipelines.
