Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of lower weir and gate sealing in a municipal pipe network, in particular to an active sealing system for a lower weir gate. Background Art
[0002] In the months with high rainfall in cities, as the flow rate of the pipe network increases, it is easy to cause rainwater and sewage to mix, which increases the water quality burden of the rainwater receiving water body and the water treatment pressure of the sewage treatment plant. In the municipal water supply and drainage engineering, the lower opening weir and the stop gate are often used in the regulating reservoir, box culvert and interception well. In the drainage network rainwater and sewage overflow control system, the water level in the drainage network can be controlled by the weir gate to divert rainwater and sewage to their respective pipe networks. The sealing of the weir gate after the lower opening weir is opened and closed is very important. The error in the production and hoisting process of the lower opening weir can easily lead to leakage on the sealing contact surface. The lower opening weir gate consists of a weir gate, a weir frame and a cylinder. In the past, the seal between the weir gate and the weir frame was passively sealed, specifically reducing the tightness between the sealing strip on the weir frame and the weir gate.
[0003] In order to reduce the difficulty of production and hoisting of the lower weir and minimize the risk of leakage or achieve zero leakage, the traditional single passive seal is replaced by an active controllable sealing system. Utility Model Content
