Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic flow limiting valves, in particular to a hydraulic flow limiting valve capable of preventing jamming. Background Art

[0002] At present, the interception wells transfer the highly polluted initial rainwater to the storage tank through the interception pipe, and discharge the less polluted mid- and late-stage rainwater to natural water bodies such as rivers and lakes, thereby separating the initial rainwater from the mid- and late-stage rainwater. In order to prevent the debris in the initial rainwater from clogging the interception pipe, it is necessary to use a screen to initially filter the garbage and debris in the initial rainwater, and then introduce the sewage into the interception pipe for separate treatment.

[0003] However, when heavy rain hits, the initial rainwater flow rate is too fast and the garbage will gradually increase. Due to the excessive garbage at the grille, the intercepting pipe will be blocked, which will seriously affect the drainage performance of the intercepting well and the flow limiting valve at the intercepting pipe will not be able to be closed. In addition, the garbage pouring into the intercepting pipe may be blocked due to the large amount, further affecting the discharge of rainwater. Utility Model Content
