Description

Wellhead assembly for municipal water supply and drainage Technical Field The utility model relates to the field of municipal water supply and drainage, in particular to a wellhead device for municipal water supply and drainage. Background Municipal water supply and drainage systems are an important component of modern urban infrastructure, and are mainly used for water conservancy facilities in urban life, production, rainwater drainage, flood control and other aspects. The wellhead device is an important intermediary for connecting the ground and the underground water delivery pipeline, and plays an important role in the processes of urban drainage, water supply, sewage treatment and the like. In conventional municipal water supply and drainage systems, the wellhead is typically constructed of a wellbore, well cover, connectors, and the like. The traditional wellhead devices are usually fixed in a fixed installation mode, cannot be flexibly adjusted, lack effective waterproof and water flow regulating functions, and particularly when water is supplied, the wellhead devices usually depend on a single opening mode and are easily affected by water flow fluctuation or water pressure impact, so that structural damage or unsmooth water flow is caused. Disclosure of utility model The utility model aims to provide a wellhead device for municipal water supply and drainage, which is used for avoiding the damage of the wellhead device caused by water flow impact during water supply. The wellhead device for municipal water supply and drainage is characterized by comprising a stacking component, wherein a mounting hole is formed in the stacking component, a shaft is arranged on the stacking component and located at the mounting hole, a cover plate is arranged at the bottom of the shaft, the outer side of the cover plate is connected with the bottom of the shaft, an annular component is arranged on the inner side of the cover plate, internal threads are arranged on the inner side of the annular component, a water supply and drainage component is arranged at the annular component, the water supply and drainage component is provided with a tubular part, a bottom cover is arranged at the bottom of the tubular part, a flange is arranged at the top of the tubular part, external threads are arranged on the outer side of the tubular part, a plurality of openings are formed in the tubular part, the external threads of the tubular part are in threaded connection with the internal threads of the annular component, the tubular part of the water supply and drainage component is matched with an underground water pipeline, the top of the underground water pipeline is in sealed connection with the cover plate, and a well cover is arranged at the top of the shaft. Further, the cover plate is arched. Further, four corners of the stacking component are respectively provided with a structural hole. Further, the notches are circumferentially and uniformly distributed on the tubular part. Further, a plurality of through holes are formed in the well cover, a filter screen is arranged on the inner side of the well cover, and one side of the well cover is movably connected with the shaft. Compared with the prior art, the utility model has the following beneficial effects: (1) The lifting height of the water supply and drainage component in the shaft is adjusted by rotating the flange, so that water flow impact under different working states can be effectively applied, damage to devices (auxiliary components) is avoided, when water is supplied, due to the fact that the impact force of water filling is large, the water supply and drainage component is adjusted to be lifted, the exposed area of a plurality of groups of water supply ports (openings) distributed on the water supply and drainage component is increased, water flow is led into an underground water conveying pipeline through the water supply ports in a split mode, direct impact of the water flow on the devices is reduced, and damage caused by hydraulic impact is avoided. (2) When the device is used for draining water, the water supply and drainage component is positioned at the tail end of the water supply and drainage component and is downwards regulated, so that a plurality of groups of water supply ports are completely distributed in the underground water transmission pipeline, the external water pipe is fixedly connected with the water supply and drainage component through the flange, the discharged water is outwards discharged through the underground water transmission pipeline, the water supply and drainage component and the external water pipe in sequence, and when the device is used for draining water, the device is positioned at the tail end of the water supply and drainage component and is less in hydraulic impact, and the water is intensively discharged, so that the drainage efficiency is improved.
