Fig. 2 pours in down a chimney the electrical schematic diagram of stopper for vacuum air pump negative pressure of the present utility model.
Embodiment
Following according to Fig. 1～Fig. 2, a kind of preferred forms of the present utility model is described.
As shown in Figure 1, be mounting point of the present utility model schematic representation, this vacuum air pump negative pressure pour in down a chimney that stopper 1 is mounted on vacuum air pump 2 by connecting tube 4 and the equipment 3 that is evacuated between;
As shown in Figure 2, the utility model comprises electric control device, solenoid valve and the warning device that circuit connects; Described electric control device comprises motor starting device and the magnetic valve controller that circuit connects;
Described motor starting device comprises stop button SB1, start button SB2 and relay J 1;
Described magnetic valve controller comprises relay J 2, J3, transformer L and rectifier ZL;
Described warning device comprises speech synthesizer IC2 CW9300, Audio Frequency Amplifier triode BG, loudspeaker B, tutorial light HL and power switch K;
This warning device also comprises three terminal regulator IC1 LM7806, and when the vacuum air pump proper functioning, to battery pack E charging, when guaranteeing the equipment sudden power, battery pack E can provide the warning device working power.
Working procedure of the present utility model is as follows:
Press start button SB2, the power switch K of closed warning device of while, relay J 1 gets at this moment, its normally opened contact JK1-2 closure, the running of the motor M of vacuum air pump, and the alternating voltage of the 220V that provides of power supply converts the VDC of 12V to behind transformer L and bridge rectifier ZL, relay J 3, its normally-closed contact JK3-1 disconnects, and normally opened contact JK3-2 closure; Then relay J 2 adhesives, its normally opened contact JK2-1 and JK2-2 are all closed, thereby solenoid valve DF is opened, and connect vacuum air pump this moment and are connected with the pipeline that is evacuated equipment, and vacuum air pump can normally vacuumize equipment; Meanwhile, three terminal regulator IC1 LM7806 charges to battery pack E;
When the vacuum extraction pump in the process that equipment is vacuumized, if in case cut off the power supply, this vacuum air pump negative pressure is poured in down a chimney stopper dead electricity immediately, this moment relay J 3 dead electricity, its normally opened contact JK3-2 also disconnects thereupon, cause relay J 2 dead electricity, its normally opened contact JK2-1 and JK2-2 also just disconnect, thereby solenoid valve DF is turn-offed, cut off to connect vacuum air pump and be evacuated the pipeline of equipment, thereby can prevent that lubricated wet goods impurity in the vacuum air pump from pouring in down a chimney enters in the equipment that is evacuated; Meanwhile, the normally-closed contact JK3-1 closure of relay J 3 triggers warning device, and this moment, battery pack E provided speech synthesizer IC2 CW9300 a stable 6V VDC, thus conducting and trigger speech synthesizer IC2
Speech trigger end on the CW9300, promptly 2 pin of chip are started working IC2, and the 3 pin output voice signal by IC2 after the amplification of triode BG audio frequency, drives loudspeaker B and sends this alarm voice signal; In addition, because after the JK3-1 closure of contact, tutorial light HL gets electric, sends the warning light optical signal, notifies the maintainer in time to fix a breakdown;
When the vacuum extraction pump equipment is finished vacuumize after, disconnect the power switch K of warning device earlier, press stop button SB1 again, this moment relay J 1 dead electricity, its normally opened contact JK1-2 disconnects, and the motor M of vacuum air pump shuts down, and relay J 3 and relay J 2 be dead electricity in succession also, solenoid valve DF disconnects, and vacuum air pump stops equipment being vacuumized; Owing to disconnected the power switch K of warning device,, Shi Buhui sends alarm signal simultaneously so triggering warning device.
The vacuum air pump negative pressure that the utility model provides is poured in down a chimney stopper and is synchronoused working with vacuum air pump, can monitor the working state of vacuum air pump, after avoiding the stall of vacuum air pump accident power-off, go in the equipment that gear oil and other materials are gone into to be evacuated by suck-back, and can in time send alarm signal, notify the maintainer to fix a breakdown, avoided property loss and waste of manpower resource.
The utility model cost is low, also applicable to current, and control such as protection such as the break-make of coal gas etc.; Safe and reliable, economic benefit is big, has bigger adaptability and generalization.
