Abstract
The utility model relates to an in-situ central control device for pneumatic valves of a nuclear power demineralization water system, which comprises a plurality of pneumatic valves, electromagnetic valves and button switches. The electromagnetic valves for controlling the pneumatic valves, relays and the button switches in the nuclear power demineralization water system are intensively arranged in an in-situ panel cabinet; power supplies are connected onto the electromagnetic valves for controlling the pneumatic valves in the manner of distribution, and meanwhile, each electromagnetic valve power supply is controlled to be switched on or off; working air sources are connected to input pipelines of the pneumatic valves controlled by each electromagnetic valve in the manner of distribution; and meanwhile, each electromagnetic valve air source is controlled to be switched on or off. According to the in-situ central control device for the pneumatic valves of the nuclear power demineralization water system, through organically combining facilities, such as a filter reducing valve in the in-situ panel cabinet, an in-situ operating state and a remote operating state can be conveniently switched, the requirements on the electromagnetic valve protection level is lowered, and the cost is saved.
Description
Technical field
The pneumatic valve that the utility model relates to a kind of nuclear power DW system demineralized water system is central control device on the spot; In the local panel cabinet, install assemblies such as solenoid valve, relay, throw over switch, filtering pressure reducing valve concentratedly; Can receive signal from tele-control system; A plurality of pneumatic valves are carried out the distribution and the switching of source of the gas, realize the local operation and the remote operation of pneumatic valve.
Background technique
Along with the progressively raising that industrial user especially nuclear power user requires automation degree of equipment, increasing industry equipment adopts pneumatic valve to replace original manually-operated gate, realizes that the remote auto of system is regulated.Pneumatic valve is realized the Kai Heguan of valve through the break-make of electromagnetic valve source of the gas, and solenoid valve itself is again the state that comes switching solenoid valve through the break-make of signal control power supply.Way commonly used at present is that solenoid valve and valve body are installed together, and power supply and source of the gas are directly received on each solenoid valve.Because industrial environment is general relatively more abominable, this just needs solenoid valve itself can stand various interference and moisture attacks.
Near a plurality of solenoid valve unifications that the utility model will concentrate on certain a set of equipment in the nuclear power DW system demineralized water system are installed in the local panel cabinet; Only need provide one road power supply and one road source of the gas to get into this dish cabinet; In the dish cabinet, power supply and source of the gas are distributed then and switches, the while is provided with throw over switch coiling the cabinet surface, can switch on the spot and long-range two kinds of different operating states; When being in the local operation state, the Kai Heguan that the local operation push-button switch through dish cabinet surface just can control valve; When being in remote status, can only be by the switch of remote signal control valve.
Summary of the invention
The utility model purpose is: the pneumatic valve that proposes a kind of nuclear power DW system demineralized water system is central control device on the spot; Especially through in the local panel cabinet, installing solenoid valve concentratedly; Realize that simultaneously pneumatic valve freely switches with remote-operated on the spot, the requirement of the control operation when satisfying nuclear power DW system demineralized water system difference operating mode.
The technical solution of the utility model is: a kind of pneumatic valve of nuclear power DW system demineralized water system is central control device on the spot; Comprise some pneumatic valves, solenoid valve and push-button switch; Solenoid valve, relay and the push-button switch of control pneumatic valve in the nuclear power DW system demineralized water system are installed concentratedly in dish cabinet on the spot; Power distribution is connected on the solenoid valve of each pneumatic valve, controls the break-make of each power of electromagnetic valve simultaneously; The work source of the gas is distributed the intake line of the pneumatic valve be connected to each electromagnetic valve, control the break-make of each solenoid valve source of the gas simultaneously.Easy switching on the spot with long-range two kinds of different operating states.
The beneficial effect of the utility model is: the utility model is through the organic assembling of the equipment such as filtering pressure reducing valve in the local panel cabinet, can conveniently switch on the spot and long-range two kinds of different operating states, reduces the requirement to the solenoid valve security level, practices thrift cost; Reduce Master Costs such as cable, source of the gas pipe; Realization when the tele-control system fault state, can freely switch to the local operation state, on the spot the control valve switch to the centralized control of a plurality of valves of certain a set of equipment.
Description of drawings
Fig. 1 is the utility model control structure block diagram
QF-incoming power switch, HR-power supply indicator, KA0-dead electricity signal relay, the long-range on the spot diverter switch of QK0-, (n gets 1,2 to the long-range on the spot transfer relay of KAn-... Corresponding each valve), (n gets 1,2 to KKn-local operation switch ... Corresponding each switch), (n gets 1,2 to the SVn-solenoid valve ..., corresponding each solenoid valve).
Embodiment
In conjunction with the control block diagram of accompanying drawing pneumatic valve and solenoid valve, embodiment is explained as follows:
In the dish cabinet a plurality of solenoid valves are installed, incoming power is 1 the tunnel, and after incoming power is connected, otherwise the HR-power supply indicator is bright, and KA0-dead electricity signal relay breaks off, and the dead electricity signal is delivered to tele-control system; When the long-range on the spot diverter switch of QK0-switches on the spot state; The long-range on the spot transfer relay of KAn-must conduct; A mutually electricity through 0n3 link tester to KKn-local operation switch, this moment can through local operation switch control electromagnetic valve coil whether electric, and then the switch of control valve.
When the long-range on the spot diverter switch of QK0-switches to remote status; The long-range on the spot transfer relay dead electricity of KAn-is closed; A mutually electricity through 0n4 link tester to remote control signal terminal, this moment by remote signal control electromagnetic valve coil whether electric, and then the switch of control valve.
