Mud hydraulic pressure table etc. is constituted.Three valve oil cylinders control unlatching and the open position of three ball valves respectively, mud valve be open or
Close spoil disposal pipeline.Water intaking valve is opened or closed into water (slurry) pipeline, and it is open-minded that the corresponding oil cylinder of ball valve, which stretches out, and retracting is
Close.Ball valve between two pipes is release valve ball, and its effect is that water inlet pipe is directly connected with discharge pipeline, is typically used as rinsing
Pipeline.The corresponding oil cylinder of ball valve stretches out to open, and retracts to close.Each ball valve will according to the difference of working condition during jacking
Ask, voluntarily controlled by operator.Therefore, a kind of it is proposed that muddy water automatic closing system of push-bench accumulator independent control.
Utility model content
Main purpose of the present utility model is to provide a kind of muddy water of push-bench accumulator independent control and close automatically to be
System, development machine is in underground activities, and three valve oil cylinders control unlatching and the open position of three valves respectively, and three valves come
Control water supply, spoil disposal and flushing pipe.When having a power failure, magnetic valve dead electricity resets the pressure energy for being stored accumulator and released
Put, close induction valve and mud valve, while opening by-passing valve, keep spoil hopper pressure, realize the pressure for keeping cutterhead spoil hopper, simultaneously
Operationally the pressure wave of suppression system, stablizes the operating pressure of deviation-rectifying system, the problem of effectively can solving in background technology.
To achieve the above object, the technical scheme that the utility model is taken is：
A kind of muddy water automatic closing system of push-bench accumulator independent control, including accumulator, it is arranged on accumulator valve
Overflow valve, pressure-reducing valve and magnetic valve, superposition hydraulic lock, control cylinder and fuel tank on seat, the control cylinder include by-passing valve
Control cylinder, mud valve control cylinder and water intaking valve control cylinder, the by-passing valve control cylinder, mud valve control cylinder and enter
Connected respectively in water valve control cylinder and pass through magnetic valve and pressure-reducing valve company in superposition hydraulic lock, every group of superposition hydraulic lock respectively
Connect, the pressure-reducing valve is connected with overflow valve, the overflow valve is connected with accumulator, the accumulator is connected with fuel tank.
Further, the magnetic valve is two-position four-way solenoid valve.
Further, the outlet line of the fuel tank is provided with hydraulic pump, the hydraulic pump and is connected with motor.
Further, the outlet line and return line of the fuel tank are equipped with filter.
Compared with prior art, the utility model has the advantages that：Development machine is in underground activities, three valves
Oil cylinder controls unlatching and the open position of three valves respectively, and three valves are to control to supply water, spoil disposal and flushing pipe.Work as power failure
When, magnetic valve dead electricity resets the pressure energy release for being stored accumulator, closes induction valve and mud valve, opens simultaneously
By-passing valve, keeps spoil hopper pressure, realizes the pressure for keeping cutterhead spoil hopper, while the operationally pressure wave of suppression system, stable
The operating pressure of deviation-rectifying system.

3 connections, the accumulator 3 is connected with fuel tank 13.
A kind of muddy water automatic closing system of push-bench accumulator independent control of the utility model, development machine is in underground activities
When, three valve oil cylinders control unlatching and the open position of three valves respectively, and three valves are to control to supply water, spoil disposal and flushing
Pipeline.When having a power failure, magnetic valve dead electricity resets the pressure energy release for being stored accumulator, closes induction valve and spoil disposal
Valve, while opening by-passing valve, keeps spoil hopper pressure, realizes the pressure for keeping cutterhead spoil hopper, while operationally suppression system
Pressure wave, the operating pressure of stable deviation-rectifying system.
Some one exemplary embodiments of the present utility model are only described by way of explanation above, undoubtedly, for
