The voltage of the high level of described DC source is 24VDC, and the low level voltage of DC source is 0VDC.
Specific works process is as follows:
Under original state, three self-locking types select switch S1 in middle position, relay in the middle of water route auxiliary reclay K1 and gas circuit
The coil of device K2 all must not electricity, the normally-closed contact of water route auxiliary reclay K1 and gas circuit auxiliary reclay K2 (11 with 12 points, 21
Point and 22 points) connect, now ball valve 2 is closed, the normally-closed contact of travel switch S2 and travel switch S4 (11 and 12
Point) disconnect.Due to the negative electrode of diode V1 and the normally-closed contact of water route auxiliary reclay K1 and the common port (11 of normally opened contact
Point) it is connected, the negative electrode of diode V3 and the normally-closed contact of gas circuit auxiliary reclay K2 and the common port (11 point) of normally opened contact
It is connected, so diode V1 and diode V3 is all not turned on, water route ball valve direct current generator M1 and gas circuit ball valve direct current generator M2
Must not be electric, it is failure to actuate.Water route ball valve 3 and gas circuit ball valve 4 are in closed mode, as shown in Figure 2.
Before rock drilling starts, when three self-locking types select switch S1 get to right position, three self-locking types select touching of switch S1
Point 1 is connected with contact 2, and the coil of water route auxiliary reclay K1 obtains electric, then its contact adhesive, and normally-closed contact (11 and 12 points, 21
Point and 22 points) disconnect, normally opened contact (11 and 14 points, 21 and 24 points) is connected, now, the 2 of water route ball valve direct current generator M1
End connects 24VDC power supply through travel switch S3, and its 1 end connects 0VDC power supply through diode V1.Now, water route ball valve direct current generator
M1 rotates forward, and as shown in Figure 6, water route ball valve direct current generator M1 drives rotary shaft 7 to rotate forward, and rotary shaft 7 drives water route ball
Valve 3 starts to open at, and is sleeved on the cam bit 8 above rotary shaft 7 and rotates with rotary shaft 7, and cam bit 8 separates with travel switch S2,
The normally-closed contact (11 and 12 points) of travel switch S2 is connected.When rotary shaft 7 turns to certain angle (such as 90 degree), cam
Sheet 8 meets travel switch S3, then the normally-closed contact (11 and 12 points) of travel switch S3 disconnects.Water route ball valve direct current generator M1 loses
Electricity, stopping action, as it is shown on figure 3, water route ball valve 3 opening action completes.Now, after water route ball valve 3 is opened, industry water is through water route
Ball valve 3 enters pipeline, the rock drill flushing cinder of match-drill.
When three self-locking types select switch S1 to be got to middle position by right position, contact 1 disconnects with contact 2, relay in the middle of water route
The coil losing electricity of device K1, then its contact disconnects, and normally opened contact (11 and 14 points, 21 and 24 points) disconnects, normally-closed contact (11 points
With 12 points, 21 and 22 points) connect.Now, 1 end of water route ball valve direct current generator M1 connects 24VDC power supply through travel switch S2,
Its 2 end connects 0VDC power supply through diode V2.Now, water route ball valve direct current generator M1 reversely rotates, as it is shown in fig. 7, water route ball
Valve direct current generator M1 drives rotary shaft 7 to reversely rotate, and rotary shaft 7 drives water route ball valve 3 to begin to shut off, and is sleeved in rotary shaft 7
The cam bit 8 of side rotates with rotary shaft 7, and cam bit 8 separates with travel switch S3, the normally-closed contact of travel switch S3 (11 with
12 points) connect, when rotary shaft 7 turns to certain angle (initial angle), cam bit 8 meets travel switch S2, then stroke is opened
The normally-closed contact (11 and 12 points) closing S2 disconnects.Water route ball valve direct current generator M1 dead electricity, stopping action.So far, water route ball valve 3
Closing motion complete, water route ball valve 3 returns to original state, as shown in Figure 2.
Gas circuit ball valve 4 opening procedure that three self-locking types select switch S1 to be got to left position by middle position, with three self-locking type choosings
Select switch S1 and got to gas circuit ball valve 4 closing process of middle position by left position, class can be carried out according to above water route ball valve 3 opening and closing process
Push away.
After rock drilling terminates, when three self-locking types select switch S1 to get to left position, water route ball valve 3 is closed, gas circuit ball valve 4 dozens
Open.In conjunction with Fig. 4 it can be seen that gases at high pressure enter pipeline by gas circuit ball valve 4, the water blowout that will remain in pipeline, Yi Miantian
Under gas cold conditions, freezing pipeline.In the hole that rock drill can be drilled by same gases at high pressure, the water of residual blows out with rock ballast, side
Phase blasting charge after an action of the bowels.
The foregoing is only preferred embodiment of the present utility model, be not used to limit this utility model, for this
For the technical staff in field, this utility model can have various modifications and variations.All in spirit of the present utility model and principle
Within, any modification, equivalent substitution and improvement etc. made, within should be included in protection domain of the present utility model.
