Description
Technical Field
The utility model relates to a water conservancy water and electricity technical field, concretely relates to remote operating system of hydraulic control valve under water of big submerged depth degree.
Background
In recent years, with the massive construction of hydraulic engineering, the use working condition of the valve is more complicated. With the improvement of environmental protection requirements, certain ecological flow must be discharged in water conservancy and hydropower engineering, and the ecological flow is taken into consideration in engineering water resource comprehensive configuration. During the construction of water conservancy projects, permanent ecological flow is designed according to the standard requirements, and the tail end of an ecological water drain pipe is provided with a corresponding ecological water drain valve for controlling and regulating the downward drainage flow. The permanent ecological water drain valve is generally designed as a flow regulating valve, is arranged at the tail end of the permanent ecological water drain pipe, and has an overhaul space and overhaul conditions. However, when the water conservancy project is in the initial stage of water storage and the diversion tunnel is closed, the project also needs to temporarily supply a certain ecological flow to the river before the water supply condition of the permanent ecological water supply system is formed.
There is a possible temporary water supply: a temporary ecological drainage pipe is arranged at the lower part of a lining bottom plate of the diversion tunnel, and is led to the flip bucket from the front of the diversion tunnel and discharged into a river channel, an underwater hydraulic control valve is arranged at the inlet end of the temporary ecological drainage pipe for on/off control, and a flow regulating valve is arranged at the outlet end for flow regulation (so as to adapt to ecological flow required by uniform lowering under a water head). In the whole water storage process, the hydraulic control valve is kept in an open state, and when water is supplied by a permanent water supply system (including an ecological flow water discharge system) of the reservoir after the reservoir finishes water storage, the valve needs to be operated to be reliably closed, so that construction conditions are created for filling and plugging temporary ecological water supply pipelines with concrete.
The existing hydraulic control valve is a valve which is opened, closed and adjusted by taking the pressure of a pipeline medium as power. The hydraulic control valve is divided into two types of diaphragm type and piston type, and its working principle is identical, and it uses the upstream and downstream pressure difference as power, and is controlled by guide valve to make diaphragm (piston) implement hydraulic differential operation, and completely automatically regulated by hydraulic power so as to make the valve clack of main valve completely open or completely close or in regulation state.
When the reservoir stores water, the 'hydraulic control valve' at the inlet end of the temporary ecological water drain pipe is always in an underwater submerged state, the requirement on energy for operating the opening/closing action of the 'hydraulic control valve' is very strict, meanwhile, the operation requirement on the valve can be realized remotely, and various requirements on safety, reliability, convenience and economy are considered, so that the difficulty is very high. The operating system of a conventional hydraulic control valve may be driven by a power source that is manual, electric, pneumatic, hydraulic, or a combination thereof. If the underwater submerging depth of the valve is large, large operation torque is needed, and the valve cannot be opened or closed manually; the electric driving mode needs to solve the problems of underwater insulation and the like of the electric actuator; the pneumatic and oil pressure driving needs to solve the problem of tightness of the cylinder and the oil cylinder, and has great risk.
