This valve the salient features are: energy storage tank to replace the present domestic several valve factory in the production of hydraulic control butterfly valve with a heavy hammer hammer, hammer potential energy into the fluid energy, not only save the long running bearing weight of energy consumption, improve the pressure of the hydraulic system performance, to avoid the runtime maintenance personnel casualty accidents and mental insecurity or fear, control mechanism and the design is novel, reasonable design, small volume, light weight, simple structure, complete functions, movements flexible and reliable, good appearance, energy-saving material saving, convenient maintenance, and do not need to stop the pump when maintenance work and so on.
The valve has a complete hydraulic system and electrical control system. The valve can be closed by manual oil pump.Valves can be fully open, fully closed, or partially open and semi-closed, which can be easily used.
This valve hydraulic station and the electrical control box can be installed in the valve body, can be separated from the valve body close to installation, the valve body can be horizontal layout, also can be installed vertically, visual field condition selection.

工作原理 Working prin

1、常规工作：
(1)阀门开启：启动电机带动油泵运转，液压油经滤网、油泵、单向阀、手动截止阀进入蓄能罐至额定压力后停止。电磁阀通电，蓄能罐内的压力油经高压胶管进入摆动油缸(以下简称油缸)的尾端，推动活塞杆伸出，带动与之相连的连杆和阀轴，使蝶板旋转开启，液压油从油缸的前部排出，经调整阀，电磁换向阀流回油箱，实现可调的无级匀速开阀。随之，蓄能罐充压力油至额定压力后油泵停止(参见液压原理图)。
(2)阀门关闭：切断电磁阀电源(或反作用型即电磁阀通电)，蓄能罐内的压力油进入油缸的前部，推动活塞杆退回，液压油从油缸尾端的快慢开角度调节杆，快关调速阀，慢关调速阀流回油箱，按预先调定的3个控制程序实现关阀。
(3)任意位置停止：蝶阀在开启或关闭过程中，切断油缸的回油，蝶板即停止在任意位置(此功能不能调节流量使用)。
2、电动油泵直接供压力油开、关蝶阀：切断蓄能罐内的压力油、关闭手动形式上阀J1、J2(参见液压原理图)。启动电机、油泵的压力油分别进入油缸的后端或前部即可实现匀速开、闭蝶阀。
3、摇动手动油泵开、关蝶阀：(切断蓄能罐内的压力油和关掉电动油泵)电磁阀得电或失电，摇动手动动油泵即可实现开、关蝶阀。
4、蓄能罐补压力油：一般情况下，蓄能罐内的油压为额定值(上限值)，当液压系统在长时间的工作状态下，由于有极微量泄漏使油压降至额定值(下限值)(仍高于工作油压值)时，压力控制器动作，启动油泵电机进行补压力油。油泵启动间隔时间为：阀门通径DN≤900大于300小时，DN≥1000大于500小时。
5、蝶阀、水泵联锁保护：当电磁换向阀出现故障(换向失控)或误操作时，联锁装置即发出跳闸信号，使水泵停止运转。
1. Routine work:
(1) valve opening: start the motor to drive the pump operation, hydraulic oil through the filter screen, oil pump, one-way valve, manual globe valve to enter the storage tank to the rated pressure to stop.The solenoid valve is energized and the pressure oil in the storage tank is pumped through a high pressure hoseInto swinging the end of the cylinder (hereinafter referred to as the cylinder), to push the piston rod, drive shaft is connected with the connecting rod and valve, rotate and open the butterfly plate and the front of the hydraulic oil from the oil cylinder, adjusted valve, electromagnetic directional valve flow back to the fuel tank, real
Now adjustable non-uniform open valve.Subsequently, the storage tank is filled with pressure oil until the pump stops (see the hydraulic schematic diagram).Electromagnetic valve (2) : the valve closed to cut off the power supply (or reaction type solenoid valve power), the front of the energy storage tank pressure oil into the cylinder, the push rod returned, the hydraulic oil from the oil cylinder end opening Angle adjusting screw rod, fast shut
The speed regulating valve, the slow speed control valve flow back to the tank, according to the preset three control procedures to realize the valve.
(3) stop at any position: in the process of opening or closing the butterfly valve, the oil cylinder is cut off and the butterfly plate is stopped in any position (this function cannot regulate the flow).
2. The electric oil pump is directly used for pressure oil and the butterfly valve: cut off the pressure oil in the storage tank, and close the manual valve J1 and J2 (see hydraulic schematic diagram).The pressure oil of starting motor and oil pump goes into the back end or front of the cylinder. The department can achieve uniform speed and close butterfly valve.
3. Shake the manual oil pump to open and close the butterfly valve: (cut off the pressure oil from the storage tank and turn off the electric oil pump) the solenoid
valve can be turned off or lost, and the pump can be opened and closed.
4, energy storage tank pressure oil: under normal circumstances, the energy storage tank for oil pressure rating (upper limit), when the hydraulic system under the working condition for a long time, because have very low leakage oil pressure drop to rating (lower limit) (still above
When working oil pressure value, the pressure controller action, start the oil pump motor to make up the pressure oil.The starting interval of oil pump is: the valve size DN is less than 900, which is greater than 300 hours, and the DN is greater than 1000 hours.
5. Butterfly valve and water pump interlock protection: when the solenoid reversing valve fails (out of control) or misoperation, the interlock device sends out the tripping signal to stop the pump running.
