An accumulator which is positioned between the hydraulic control valve group and the hydraulic station is connected with the hydraulic control valve group through a hydraulic control one-way valve and is connected with the gate through the hydraulic control valve group. The accumulator and the hydraulic station provides a power source for opening and closing the gate. The hydraulic control valve group realizes the control of opening and closing gates and the control of opening and closing force, to satisfy the needs of opening, closing, quickly opening, and quickly closing gates under various operating conditions in a pump station. Particularly, when power failure happens by accident in a pump station, a power source can be provided by the accumulator to quickly close gates, and therefore, a pumping unit and buildings at the pump station can be protected.
Description
The utility model relates to gate valve, particularly relates to the gate valve that energy accumulation type hydraulic opens and closes.
Existing electronic winding type gate, Weight type gate, its hoisting capacity is limited, and the adjustable-speed of keying is poor, often can not close when moving water.
And the fluid pressure type gate, the keying of its gate provides energy by oil pump electricity group, if pumping plant is met and had a power failure suddenly when needing closed shutter, then can't close; And the finite energy that partly provides of hydraulic power, can not satisfy the requirement that all gates are closed simultaneously.
The purpose of this utility model is to provide a kind of energy accumulation type hydraulic stop gate, can satisfy rapid closed shutter when pumping plant is prominent meets power failure, and can satisfy closing or starting gate under the various operating conditions of pumping plant.
The technical solution of the utility model is as follows:
The utility model includes Hydraulic Station, gate, the hydraulic control valve group, the hydraulic control valve group is connected with gate with Hydraulic Station respectively, accumulator is between Hydraulic Station and hydraulic control valve group, accumulator is connected with the hydraulic control valve group by the hydraulic control one-way valve group, and is connected with gate by the hydraulic control valve group.
Its accumulator is connected by one or more accumulator.
Hydraulic Station and accumulator provide power source for the keying of gate, and the hydraulic control valve group realizes controlling to the opening and closing of gate, and satisfying prominent chance of pumping plant can rapid closed shutter and pumping plant closing or starting gate under various operating conditions when having a power failure.
Advantage of the present utility model is as follows:
1. the power source of gate opening/closing system is made up of accumulator and Hydraulic Station.Can guarantee has reliable action at the situation tail gates of there is electric power or not, with the safety of protection water pump assembly and pumping plant building.
2. the Oil pump electrical machinery that utilizes smaller power at ordinary times with energy storage in accumulator, discharge in the short time during to needs, produce more high-powerly, this power can be several times even tens times of power of motor, has so just saved a large amount of energy and operating cost.
3. the movement velocity of gate and working procedure are to put forward by waterpower transient process theory, and through practice test and definite, each stage speed of service and to switch stroke all adjustable.
4. electric, gas control system aspect use programmable logic controller, use, maintenance simply, conveniently, reliably are convenient to and computer networking, are implemented in line traffic control.
