Technical Field
The utility model relates to the technical field of underground pipelines, in particular to an assembled air valve well.
Background
The air valve in the water supply network is mainly used for exhausting gas in the pipeline at the highest point or in the place where the pipeline is closed, dredging the pipeline, enabling the pipeline to normally operate, if power failure and pump stopping occur suddenly, negative pressure can occur in the pipeline to cause vibration or rupture of the pipeline, and the air valve can exhaust at any time to ensure the safety of the pipeline.
The air valve well is a space for placing a gate, which is arranged when the air valve well needs to open and close part of pipeline operation or overhaul operation, and is used for installing and arranging an air valve and the like in the space, so that the inspection, the exhaust and the dredging of a pipeline system are facilitated.
At present, a valve well for water supply in the market is mostly a concrete cast-in-situ well, and the problems of high construction difficulty, long construction period, high construction cost and the like caused by large excavation depth exist.
Disclosure of Invention
The utility model aims to provide the assembled air valve well which has the advantages of simple structure, reasonable design, convenience in installation, short construction period, convenience in maintenance and lower cost.
In order to achieve the above purpose, the present utility model is realized by the following technical scheme:
the utility model provides an assembled air valve well, includes water supply main line, three-way pipe, ventilation branch pipe, air valve, and water supply main line passes through rigid joint and three-way pipe connection, and the three-way pipe other end is connected with ventilation branch pipe, and ventilation branch pipe stretches out the rubble bed course in underground, still includes preset valve well bottom plate, valve well barrel, valve well roof and breather pipe, sealed well lid, valve well bottom plate is located on the rubble bed course, and air valve and ventilation branch pipe connection, valve well barrel passes through cement mortar and is connected with valve well bottom plate, the valve well roof passes through cement mortar and is connected with the top of valve well barrel; one end of the vent pipe extends into the valve well through the valve well cylinder body, the other end of the vent pipe extends out of the ground, and the sealing well cover is arranged on the valve well top plate.
Further, the rigid joint is a welded joint or a flange joint.
Further, a hanging hole is formed in the outer wall of the valve well barrel.
Further, the valve well cylinder body is a cube or a cylinder.
Compared with the prior art, the utility model has the following advantages:
the prefabricated air valve well is smaller, a water accumulation pit is not required to be designed, the amount of excavation engineering is reduced, the construction period is short, the construction is convenient, and the cost is low; the outer wall of the valve well cylinder body is provided with a hanging hole, so that the valve well cylinder is convenient to install; the operation is convenient, and the overhauling personnel can open the well cover to perform on-site operation; the underground operation of the traditional valve is not needed, and the safety operation of overhauling staff is ensured.
