In order to realize pulse cooling function, need the first switch valve 13 and second switch valve 21 to have fastThe function of opening and turn-offing, therefore, preferably, the first switch valve 13 and second switch valve in this programme21 are Pneumatic butterfly valve, and certainly, those skilled in the art can also select pneumatic ball valve or Pneumatic gate valve etc.Pneumatic rapid cut-off valve.
Because cooling water source is for producing cooling water, after long-play, in pipeline, may retain dirtImpurity such as dirt mud etc., thus the normal survey of the accurate valve member instrument such as solenoid valve and electromagnetic flowmeter affectedAmount and work. In order to get rid of the impurity in pipeline, ensure each element normal operation, preferably, theOn the first cooling line 1 before one flowmeter 11, be connected with and lead to the blowdown branch road 4 of casting well, blowdown is propped upRoad 4 is provided with on scum cock valve 41, the first cooling lines 1 and is provided with and is positioned at first flow meter 11 HesThe first service switch valve 18 between blowdown branch road 4 junctions. So arrange, need to get rid of the assorted of pipelineWhen matter, only the first service switch valve 18 need cut out, open scum cock valve 41 will produce cooling water fromBlowdown branch road 4 by and flow to casting well in, thereby can enter the technological parameter of each follow-up components and partsRow is confirmed.
Preferably, on the first cooling line 1, be also provided with and be positioned at the first service switch valve 18 and first flowPressure maintaining valve 17 between meter 11, pressure maintaining valve 17 can reduce the pressure of cooling water source, thereby ensures firstStable cooling water flow is provided in cooling line 1.
Preferably, on the first cooling line 1, be provided with between pressure maintaining valve 17 and first flow meter 11The second service switch valve 16. In the time that pressure maintaining valve 17 needs repairing, can close the second service switch valve16 and the first service switch valve 18, then by pressure maintaining valve 17 detachable maintainings.
It should be noted that, on the first cooling line 1, be provided with and be positioned at the second service switch valve 16 and firstWater temperature water-pressure survey unit 15 between flowmeter 11, in real time measuring the first cooling line 1Water temperature and hydraulic pressure, thus be convenient to timely control and regulation.
It should be noted that, on the first cooling line 1 after the first switch valve 13, be connected with emergent water pipeOn 6, the first cooling lines 1 of road, be provided be positioned at the first switch valve 13 and emergent water lines 6 junctions itBetween the first check valve 14, the first check valves 14 along cooling water source to water jacket crystallizer direction one-way conduction,In emergent water lines 6, be provided with emergency button valve 61 and the second check valve 62, the second check valves 62 along answeringAnxious water source is to the direction one-way conduction of water jacket crystallizer. Emergent water lines 6 can produced cooling water deficiencyOr first cooling line 1 while going wrong to water jacket crystallizer emergency service cooling water, the first check valve 14For ensureing that emergent water source can not flow to the upstream of the first cooling line 1, the second check valve 62 is for ensureingCooling water in the first cooling line 1 can not flow in emergent water lines 6. Concrete, emergency button valve61 can be Pneumatic butterfly valve.
It should be noted that first cooling after the first cooling line 1 and emergent water lines 6 junctionsOn pipeline 1, be connected with and drain branch road 5. Concrete, drain on branch road 5 and be provided with and drain switch valve 51,This drains switch valve 51 and is specifically as follows pneumatic ball valve.
In the aluminium alloy casting water system that the utility model provides, the adjusting of discharge is mainly by carrying out unitPart solenoid valve and detecting element electromagnetic flowmeter are realized, the closed-loop adjustment of PLC electric-control system compositionSystem realizes the accurate control of discharge, 40～500 cubic meters/hour of adjustable ranges, and precision is less than or equal to 1%,The adjustment process time is less than 12 seconds, and the adjustable cycle period of ratio switch time is 2 seconds to the maximum, without water hammerProblem.
