A hydraulic flow limiting gate is a type of gate that can be controlled by hydraulics and is usually used to control the flow of water. The working principle of the hydraulic flow limiting gate is to control the piston movement of the hydraulic cylinder to adjust the opening and flow rate of the gate, so as to achieve the purpose of restricting the water flow. This type of gate usually consists of hydraulic cylinders, rams, gate shafts and control systems, etc., which can be customized and adjusted according to actual needs to meet a variety of different flow and pressure requirements.
Features of the hydraulic current limiting gate:
1. The gate structure is a flat frame structure, made of 304 stainless steel, anti-corrosion, long service life, polyurethane rubber waterproof seal, good sealing performance, hydraulic drive, large power of the cylinder, stable operation.
2. The liquid level sensor control takes precedence over the rain gauge control, and the rain gauge. The rain gauge is composed of a rain sensor, a water collection bucket, a collection pipe, etc., which collects rainfall information in real time, and when the rainfall or rainfall time set by the system is reached, the rain gauge will feedback the signal to the control system;
3. According to the rainfall time, rainfall duration, liquid level height and other parameters, the PLC control cabinet realizes intelligent control, and automatically adjusts the opening and closing time of the sewage gate and the rainwater gate to prevent a large amount of rainwater from entering the sewage pipeline;
4. The automatic control system is used to remotely control the gate switch, and the gate switch information will be sent to the management personnel in real time, and the system can meet the on-site manual and electric operation, and has the function of remote control;
5. Mains or solar power supply is adopted, which is not only energy-saving and environmentally friendly, but also solves the normal operation in the environment without mains. At the same time, it provides a mains interface, which can realize the dual-purpose of solar energy and mains.
Fields of application. 1. Sewage interception of the confluence pipe network, initial rainwater drainage, connection between the drainage pipe of the community and the municipal road pipe network, the connection of the pipeline at the intersection of the road, the drainage of the river and the rain and sewage diversion of the old community.
2. Remediation of urban black and odorous water projects, such as factories, villas, residential quarters, commercial buildings and other underground rainwater main pipe networks or branch pipe networks under construction or renovation projects, to achieve the diversion of rain and sewage in the underground rainwater pipe network, source control and sewage interception.
In short, the structure of the hydraulic current limiting gate is complex, but through the coordination and cooperation of various components, the control and current limiting effect of the gate can be realized.
