Butterfly valve shaft mounting structure
Technical field
The utility model relates to water-supply technology field, particularly relates to a kind of butterfly valve shaft mounting structure.
Background technology
Valve well is that the valve of underground utilities and underground pipeline (as tap water, oil, natural gas line etc.) is in order to facilitate when carrying out the operation of opening and closing part pipe network or upkeep operation at needs, a hole (or well) of similar cubicle is just set, by mounting arrangements such as valves in this hole, be convenient to make regular check on, clean and dredging pipeline, prevent the hinge of line clogging.
But the poor effect such as valve well waterproof in prior art, in view of this, be necessary to provide a kind of butterfly valve shaft mounting structure.
Utility model content
Technical problem to be solved in the utility model is, for above-mentioned deficiency of the prior art, to provide a kind of butterfly valve shaft mounting structure exactly.
The utility model solves the technical scheme that its technical problem adopts:
A kind of butterfly valve shaft mounting structure, it comprise base plate, with the vertically arranged borehole wall of base plate and the cover plate that is positioned at above the borehole wall, described base plate, the borehole wall and cover plate enclose in a confined space, the described borehole wall runs through respectively and is provided with the first water service pipe and the second water service pipe, described first water service pipe and the second water service pipe are tightly connected by expansion joint, and described first water service pipe or the second water service pipe are provided with butterfly valve.
As further improvement of the utility model, described base plate is reinforced concrete floor, and described cover plate is reinforced concrete cover plate.
As further improvement of the utility model, be provided with bed course below described base plate, below bed course, be provided with sump.
As further improvement of the utility model, be provided with bearing above described cover plate, above bearing, be provided with well lid.
The beneficial effects of the utility model are, by stretching structure and butterfly valve in the utility model, can effectively to flow cavitation result, and this butterfly valve shaft mounting structure is simple, sealing is better.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the schematic diagram of butterfly valve shaft mounting structure in the utility model one specific embodiment.
Detailed description of the invention
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
Shown in ginseng Fig. 1, the utility model discloses a kind of butterfly valve shaft mounting structure, it comprise base plate 10, with the vertically arranged borehole wall 20 of base plate and the cover plate 30 that is positioned at above the borehole wall, described base plate 10, the borehole wall 20 and cover plate 30 enclose in a confined space, the described borehole wall runs through respectively and is provided with the first water service pipe 41 and the second water service pipe 42, described first water service pipe 41 and the second water service pipe 42 are tightly connected by expansion joint 43, and described first water service pipe or the second water service pipe are provided with butterfly valve 44.
Preferably, in the utility model, base plate 10 is reinforced concrete floor, and cover plate 30 is reinforced concrete cover plate.
Further, below described base plate, be provided with bed course 11, below bed course, be provided with sump 12.Be provided with bearing 31 above described cover plate, above bearing, be provided with well lid 32.
By stretching structure and butterfly valve in the utility model, can effectively to flow cavitation result, and this butterfly valve shaft mounting structure is simple, sealing is better.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on manual, must determine its technical scope according to right.
