Embodiment Construction
[0030] Please refer to the attached figure 1 As shown, the present invention is a butterfly valve well with an extension rod, in which a butterfly valve 1 is installed. It consists of several parts.
[0031] Wherein, the well shaft 4 is arranged between the well chamber cover plate 2 and the concrete cover plate 5 , which is a brick well shaft 4 .
[0032] The extension rod 3 vertically passes through the concrete cover 2, the shaft 4 and the well chamber cover 2 from top to bottom, and its bottom is connected to the butterfly valve 1, so that the operator can realize the operation of the butterfly valve 1 on the ground. On and off control.
[0033] The upper part of the extension rod 3 is provided with a split ring 8, and the split ring 8 is fixed on the concrete cover plate 2 through expansion bolts 9, thereby positioning the extension rod 3.
[0034] The protective cover 6 is covered on the top of the extension rod 3, and it is fixed on the concrete cover plate 5, which ...

The invention relates to a butterfly valve pit with a lengthening bar. A butterfly valve is arranged in the butterfly valve pit. The butterfly valve pit comprises a pit chamber cover plate, the lengthening bar, a shaft, a concrete cover plate, a protection cover and a backfill soil layer. The shaft is arranged between the pit chamber cover plate and the concrete cover plate. The lengthening bar vertically penetrates the concrete cover plate, the shaft and the pit chamber cover plate from top to bottom, and the bottom of the lengthening bar is connected to the butterfly valve. A split collar is arranged on the upper portion of the lengthening bar and fixed to the concrete cover plate through expansion bolts. The top of the lengthening bar is covered with the protection cover, and the protection cover is fixed to the concrete cover plate. The backfill soil layer is arranged outside the protection cover. The butterfly valve pit with the lengthening bar is simple in structure, and subsequent maintenance is facilitated so that operators can control the butterfly valve to be opened and closed on the ground.
Description
【Technical field】 [0001] The invention relates to a butterfly valve well and a construction method thereof, in particular to a butterfly valve well with an extension rod and a construction method thereof, and belongs to the technical field of water supply pipeline equipment. 【Background technique】 [0002] The water supply pipelines of the prior art are basically laid in the mode of underground direct burial, and some depths reach about 5m. After the pipeline is officially in operation, it is very difficult to inspect and operate the equipment in the relevant inspection well. [0003] Therefore, in order to solve the above technical problems, it is indeed necessary to provide an innovative butterfly valve well with an extension rod and its construction method, so as to overcome the above-mentioned defects in the prior art. 【Content of invention】 [0004] In order to solve the above problems, the first object of the present invention is to provide a butterfly valve well wi...
