Problems solved by technology

[0002] In the field of water supply and drainage engineering, due to the small amount of drainage in the dry season, the general flushing device cannot be operated in the dry season, and even if there is a flushing device that can be used in the dry season, its long-term use will consume a lot of energy, and the pollution in the pipeline Things need to be washed frequently to avoid pollutants from accumulating and clogging pipes. Therefore, how to design an energy-saving flushing equipment to store the water level in the dry season to the set water level and wash away the pollutants is the current problem.

Embodiment 1

[0028] Such as figure 1 The self-flushing hydraulic balance valve structure shown in —7 includes a pipeline 1, and a valve is arranged in the pipeline 1, and the valve includes a valve frame 2 fixed on the pipe wall of the pipeline 1, and a rotating shaft 3 is fixed on the valve frame 2. The movable valve plate 4 is hinged on the shaft 3, the two sides of the movable valve plate 4 are sealed with the valve frame 2, and the bottom is sealed with the pipeline 1, and the movable valve plate 4 is divided into the upper movable valve plate 4.1 and the lower movable valve plate 4 with the rotating shaft 3 as the boundary. For the movable valve plate 4.2, the distance from the center of gravity of the upper movable valve plate 4.1 to the rotating shaft 3 is greater than the distance from the center of gravity of the lower movable valve plate 4.2 to the rotating shaft 3. Based on the principle of leverage, when the water storage height exceeds the movable valve plate 4, it will cross ...

Embodiment 2

[0037] Such as Figure 8 -14 shows:

[0038] The bottom surface of the counterweight 6 is located below the bottom surface of the lower movable valve plate 4.2, the counterweight 6 and the lower movable valve plate 4.2 form a stepped groove, and the top of the fixed valve plate 8 is sealed with the stepped groove. To ensure the sealing effect, the structure of the limiting plate 7 ensures that the maximum rotation angle of the movable valve plate 4 is still 90°, and the valve is opened after the movable valve plate 4 rotates counterclockwise to realize flushing of the pipeline. The invention can realize continuous flushing of the pipeline 1 without external force, the valve has a simple structure, is easy to manufacture and install, has good practical effect, can be used in dry season, and has high market application value.

Abstract

The invention discloses a self-flushing hydraulic balance valve structure which comprises a pipeline. A valve is arranged in the pipeline and comprises a valve frame fixed on the wall of the pipeline, a rotating shaft is fixed on the valve frame, a movable valve plate is hinged to the rotating shaft, the two sides of the movable valve plate and the valve frame are matched in a sealed mode, the bottom of the movable valve plate is matched with the pipeline in a sealed mode, the movable valve plate is divided into an upper movable valve plate body and a lower movable valve plate body by the rotating shaft, and the distance between the gravity center of the upper movable valve plate body and the rotating shaft is larger than the distance between the gravity center of the lower movable valve plate body and the rotating shaft. The self-flushing hydraulic balance valve structure has the advantages that a sewage pipe can be automatically and continuously flushed without external power and additional control devices; airtightness between the valve plate and the valve frame is good, sewage leakage is prevented, and the best retaining effect is achieved; the hydraulic balance valve is made of the anti-corrosion stainless steel material, and the service life of the hydraulic balance valve is prolonged; the structure is simple, mounting is convenient, and modification of existing pipes is easy to achieve.

Description

technical field [0001] The invention relates to the technical field of water supply and drainage valves, in particular to a self-flushing hydraulic balance valve structure. Background technique [0002] In the field of water supply and drainage engineering, due to the small amount of drainage in the dry season, the general flushing device cannot be operated in the dry season, and even if there is a flushing device that can be used in the dry season, its long-term use will consume a lot of energy, and the pollution in the pipeline Things need to be washed frequently to avoid the accumulation of pollutants and blockage of pipes. Therefore, how to design an energy-saving flushing equipment to store the water level in the dry season to the set water level and wash away the pollutants is the current problem. Contents of the invention [0003] The present invention aims at the above-mentioned technical problems and provides a self-flushing hydraulic balance valve structure, whic...
