Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
With reference to Fig. 1 ~ Fig. 3, the automatic pressurize hydraulic control valve of a kind of heavy hammer type electric control equipment, described electric control equipment comprises the photoelectric encoder that is installed in the automatic pressurize hydraulic control valve of the heavy hammer type actuator, described photoelectric encoder by the D/A change-over circuit with in order to link according to operating mode control upper-position unit DCS control system be connected, described upper-position unit DCS control system is connected with described power amplification circuit, and described power amplification circuit is connected with the automatic pressurize hydraulic control valve of heavy hammer type actuator.
Described upper-position unit DCS control system comprises that also described display modular is connected with display screen in order to show the display modular of current working.
Described upper-position unit DCS control system be connected in order to the human-computer interaction module that carries out execute-in-place.
Described upper-position unit DCS control system is provided with the remote communication interface with the communication of long-range DCS control system.
In the present embodiment, the control power supply can be each grade such as 220V, 110V, 24V, and AC/DC universal, and is general fully with the uninterrupted system of field power supply, need not to put in addition power supply, improved stability.
Control system adopts the socket wiring, has reduced the error of polylinker, and circuit is arranged simple, changes easy to maintenance.
Adopt the optoelectronic switch detection position, accurately sensitive, the security level height adopts modular design, but function also isolated operation capable of being combined is supported online and the off-line update routine, has avoided shutting down and has caused unnecessary loss.
Various operating modes generally all require throttle down when shutting down or having a power failure.This valve electric control system all is furnished with control loop and remote interlocking control loop on the spot.Control loop is mainly used in field adjustable on the spot, generally all uses the remote interlocking control loop during proper functioning.
Local operation: power turn-on switch QF, power supply indicator is bright; The complete shut-down tutorial light is bright.Throw over switch SW is threaded to " on the spot " position.
Drive valve: by opening valve button SB1 on the spot, A.C. contactor KM is charged, and the main contact closure drives the Oil pump electrical machinery operation, and the oil pump tutorial light is bright, and the while main electromagnetic valve gets electric, and hydraulic oil enters oil cylinder through flow control valve, high-pressure rubber pipe, promotes piston, lifts weight and drives valve.
Row detected when optoelectronic switch was to valve position when driving valve, and CPU carries out computing, arrived 15 when spending (preestablish, scene can revise), and CPU gives an order, and valve sends out 15 degree signals; Drive valve behind the standard-sized sheet position, the standard-sized sheet tutorial light is bright; Automatically pressure-retaining system starts simultaneously: motor continues to the accumulator pressurising; When pressure reached set point KP, oil pump was shut down.
Automatically pressurize: when system leak, pressure are reduced to pressure switch KP, the KP closure, oil pump starts ftercompction automatically, reaches pressure switch set point motor and stops.KP sets and is about 10MPa, all mixes up when generally dispatching from the factory.
If KP is provided with wrong (on the low side), weight begins to descend and oil pump does not start yet, when standard-sized sheet position position limit switch discharges, oil pump also automatically ftercompction to the KP value.
If it is wrong that KP cooperates with relief valve setting, oil pressure arrives flooding point earlier, and then oil pump can not be shut down; When operation surpassed the scheduled time, system promptly sent alarm signal, and the prompting operator hunt leak or reset.
Close valve: by closing valve button SB2 on the spot, main electromagnetic valve YV1 dead electricity, is got back to fuel tank at oil cylinder internal pressure main electromagnetic valve, and weight falls, and valve rod and butterfly plate rotation realize fast quick-closing valve.The quick closing valve time can be adjusted by rotation quick closing valve modulating valve handwheel.
Row detected when optoelectronic switch was to valve position when closing valve, and CPU carries out computing, arrived 75 when spending (preestablish, scene can revise), and CPU gives an order, and valve sends and closes 75 degree signals, so that the termination of pumping of upper-position unit interlocking, valve enters the Slow Close state.The Slow Close time can be adjusted by the Slow Close modulating valve, with effective elimination pipeline water hammer.
CPU sent the complete shut-down signal after the pass valve put in place, and the complete shut-down tutorial light is bright.
Stop: at positive normally open valve or close in the valve process, all can pass through stop button SB3 abort actions, oil pump stops or main electromagnetic valve YV1 gets electricly, allows valve stop at the arbitrary position, debugs to make things convenient for the user.
Should avoid using this function in the quick closing valve process, in order to avoid hydraulic system is formed impact.
Remote operation: throw over switch SW is threaded to " long-range " position, and it is bright far to control tutorial light; The control that can drive valve respectively, close valve, stop valve this moment by control switch S B4 far away, SB5, SB6; And can interlock with the pipeline main frame, realize the pump valve joint control.
Joint control is driven valve: open earlier pump, after drive valve: central control chamber starts water pump, behind the delay scheduled time, long-range DCS valve opening signal input, valve by preset program open automatically, pressurize.
To set up retard time is zero, can realize that pump valve starts simultaneously.
Jockey valve, after open pump: by the long-range valve button SB4 that opens, pump start, valve is opened thereupon.When valve opening to set angle, valve sends and opens the pump signal, central control chamber starts water pump.
SB4 opens the pump signal as if sending simultaneously, can realize that also pump valve starts simultaneously.
Joint control is closed valve: pump valve normally cuts out simultaneously: water pump is shut down, or the unit fault, and long-range DCS closes the valve signal input, the commutation of solenoid valve YV dead electricity, and valve closes valve by preset program.
Close valve, back termination of pumping earlier: press long-range pass valve button SB5, valve closing; When positions are spent to predefined 75 in the pass, send signal, the central control chamber termination of pumping.
The fault loss protecting: when valve control system fault dead electricity, valve is closed immediately, and order is sent if dead electricity is closed valve, or a distant place sends the accident dead electricity and close the valve order, and valve is closed automatically by preset program.But the while is the manual unlocking normally closed cut-off valve also, and valve also will be closed by preset program.
The remote monitoring signal: but control system except that receiving remote is driven valve, closes valve, is stopped, the water pump state signal, also export 90 ° of standard-sized sheet positions, 0 ° of complete shut-down position, various states signals such as valve location 4-20mA signal are for long-range DCS monitoring.
Manually-operable: valve dead electricity, and when need opening, this moment press out Fa Key in the UPS power supply, it is electric that solenoid valve gets, or manual solenoid valve, and fluid is connected, and shakes hand pump, and pressure oil promptly directly enters oil cylinder through high-pressure rubber pipe, the promotion piston, the drivening rod system drives valve.
When UPS powers, also can send and close the valve order, oil cylinder internal pressure oil is got back to fuel tank through closing throttle valve, high-pressure rubber pipe, stop valve soon, slowly, and under the effect of weight potential energy and moving Hydraulic Moment, valve rod and butterfly plate rotation realize closing valve.
