Abstract
The utility model discloses an intelligent solenoid valve box which is particularly suitable for a remote pneumatic control system having high requirements for reliability and stability. Each solenoid valve is provided with an opening and closing plug board. An air source is connected with a manual valve and a filter reducing valve through a pipeline, and then is connected with air inlets of all the solenoid valves through 2-12 opening and closing plug boards. The solenoid valves are controlled by a PLC. When one solenoid valve is damaged, the solenoid valve can be replaced timely in an on-line mode. Each solenoid valve forms a control unit, so that the control mode of the whole pneumatic control system is changed from centralized control to decentralized control. Each solenoid valve has the fault self-diagnosis function so that a fault can be found at the first time and eliminated. Due to the fact that an intelligent unit of the solenoid valve box is a PLC itself, the intelligent unit replaces an intermediate relay which controls the solenoid valves, and the fault rate of the solenoid valve box is lowered. The control information and state information of field solenoid valves and the self-diagnosis information of the solenoid valve box are all sent to an upper computer through a DP bus, therefore, a large amount of wiring is reduced, manpower cost for maintenance is lowered, and possibility is provided for realizing remote field control.
Description
Technical field
The utility model relates to a kind of intelligent electromagnetic clack box, particularly is applicable to pneumatic control system reliability, stability requirement are handled the valve pneumatic control system than higher electric field water.
Technical background
The general solenoid valve case is made up of solenoid valve group and collecting plate, and the solenoid valve group generally is made up of 2 to 12 solenoid valves.Three air flues are arranged on the collecting plate, and the centre is intake duct, and both sides are air outlet channel, and air outlet channel generally connects baffler, and intake duct generally connects (reduction valve after filtration) instrument air.This is the simplest solenoid valve box, does not have the local intelligent observation and control ability, does not have the self-diagnosis of trouble cutting capacity, can not find fault during urgency, not with long-range DCS or PLC ability to communicate.The solenoid valve logical action is directly controlled realization by DCS in the long-range master control cabinet or PLC.Such telecontrol needs a large amount of leads to draw, cause DCS or PLC can not from the scene too away from, to requiring distance field telecontrol far away, can not realize.
Also have an importance, each solenoid valve in the solenoid valve group just can keep in repair because public air outlet channel and intake duct if wherein a solenoid valve damages, need whole solenoid valve box to quit work, and changes solenoid valve.It also is like this enabling standby solenoid valve.
Summary of the invention
In order to remedy general solenoid valve case deficiency, the utility model provides a kind of intelligent electromagnetic clack box.This solenoid valve box should guarantee the reliable and stable operation of pneumatic control system, has self-diagnostic function, can directly judge opening circuit and short-circuit conditions of solenoid valve.The solenoid valve that rate of fault is high in case damage, can be changed under other part normal operation of solenoid valve box fast.
The technical solution used in the present invention is: a kind of intelligent electromagnetic clack box, it comprises solenoid valve, the filtering pressure reducing valve of the baffler of exhaust duct end and admission line end, it also comprises the keying plate, described solenoid valve is 2-12, each solenoid valve is provided with one and opens and closes plate, after source of the gas adopts pipeline to connect hand control valve and filtering pressure reducing valve, open and close the suction port that plate connects each solenoid valve through 2-12, the other end of suction tude seals with plug one, after first relief opening of a described 2-12 solenoid valve adopts pipeline and separately keying plate is connected, an end that converges pipeline connects first baffler, the other end seals with plug two, after second relief opening of a described 2-12 solenoid valve adopted pipeline and separately keying plate is connected, an end that converges pipeline connected second baffler, and the other end usefulness plug three seals; Described solenoid valve adopts the PLC range controller to control.
Described keying plate is concentrated and is arranged on the collecting plate.
Described PLC range controller adopts switching value input unit, switching value output unit, fault self-diagnosis unit and communication unit to be electrically connected.
Described solenoid valve is selected two five-way air-operated solenoid valves for use.
Adopt the intelligent electromagnetic clack box of technique scheme to adopt 24 volts of dc powered solenoid valves.Select the small PLC of band Siemens DP bus communication interface for use, its configuration output suitable with the line solenoid valve number of turns is counted and the analog amount input is counted.The analog amount input point provides a diagnostic signal input point for each electromagnetic valve coil, can directly judge opening circuit and short-circuit conditions of solenoid valve.Reserve a part of switching value input point, do on-the-spot switching value input and use.This PLC has redundancy control capability simultaneously, and namely after bus communication broke down, the logic built controller was opened automatically, finishes safety interlocking control, and normal valve operation.The great like this control reliability that improved.This PLC is as the intelligent control unit of solenoid valve box.
For realizing that solenoid valve can dismounting function in real time, collecting plate is selected independent keying collecting plate for use, its sharpest edges is not have the situation that other elements were revealed or polluted to pressurized air with gas dismounting solenoid valve, the valve position of Yu Liuing does not need blind plate yet simultaneously, pushing independent keying plate after valve is good and sound open gets final product, each valve position has independent switching function, when closing a certain valve position, be not only to close suction port, also closed simultaneously relief opening, prevent inner gas blowby, so just reached the purpose that need not the online dismounting solenoid valve of blind plate.
The beneficial effects of the utility model are:
Online replacing when energy was anxious when 1) solenoid valve damaged.This just guarantees the long-term proper functioning of whole solenoid valve box;
2) application of intelligent electromagnetic clack box make each solenoid valve box have a control unit of one's own, thereby whole pneumatic control system becomes decentralized control by centralized control, improves whole system stability;
3) each solenoid valve box has fault self-diagnosis function, can the very first time find fault, fixes a breakdown.The assurance whole system is worked smoothly;
4) because the solenoid valve box intelligent cell itself is exactly a PLC, it substitutes the auxiliary reclay of control solenoid valve, has reduced the solenoid valve box rate of fault;
5) owing to have field-bus interface, on-the-spot electromagnetic valve information, status information, and the solenoid valve box self-diagnosis information, all deliver to upper-position unit by the DP bus, reduced a large amount of wirings, the human cost of reduce safeguarding, thus possibility provided for the realization away from field control.
