SU1416350A1 - Apparatus for remote control of driverъs brake valve - Google Patents

Abstract

The invention relates to rail transport. The purpose of the invention is to improve traffic safety and enhance functionality by obtaining supercharging pressure in the surge tank, when releasing the brakes. The device contains two electropneumatic valves 2 and 1 for tempering and deceleration and a switching valve 3 with two control pistons 11 and 12 of different diameters. The device is installed between the crane body 4 of the driver and the gearbox 5 and connects to them with air ducts. The difference in the diameters of the pistons 11, 12 ensures the priority of the process s, t1 -capital braking before the process of the CKa brakes, and the presence of the dividing walls 10 on the valve 3 allows using the valves 1 and 2 to obtain an extra charge pressure in the surge tank. 2 Il.

FIG. 1 shows a remote control device for a driver's crane at the charging positions with its bottom; in fig. 2 - the same in the overlapped positions and during braking.

The remote control device contains two electro-pneumatic braking and tempering valves 1.2 and a switching valve 3 connected to the crane 4 of the driver and the gearbox 5 by air ducts from the surge tank 6, the feed line 7, the surge chamber 8 and the stabilizer 9.

The switching valve 3 is equipped with self-sealing, imis separating partitions 10 and control pistons 11, 12 of smaller and larger diameters. The piston 12 has a throttle bore 13 in its bodies. The difference in diameter of the pistons ensures that the service braking process takes precedence over the brake release process when valves 14 and 15 are accidentally opened at valves 1 and 2 (valve 1 is de-energized and valve 2 is under voltage) equalizing tank equal to charge and super charge, the switching valve is in the left position. During service braking and overlapping, the PC is in the right position due to the action of compressed air And springs 16. Channel 6 has an outlet 17 to valve 1. The valve 1 is connected to the atmosphere through channel 18, cavity 19 of piston 12, channel 20 and throttle 21 service braking The reducer 5 communicates with the switching valve 3 channel 22. The valve 2 communicates with the supply line 23, and with the equalizing chamber of the driver's crane - channel 24, cavity 25 of the piston 11 and channel 26.

The device works as follows.

When the brakes are charged (Fig. 1), the electropneumatic valves 1 and 2 are under voltage. 15 valve raised, and compressed air

Highways through channels 23 and 24 through cavity 25 and. channel 26 enters the equalizing chamber of the driver’s crane. The switching valve is in the left position and the channel 22 is connected to the channel 8. The valve 14 of the electropneumatic valve 1 is closed, isolating the balance tank from the atmosphere.

When the train position (Fig. 1) valve 2 is de-energized and the valve 15 is closed. The switching valve 3 is in the left position. In this case, the reduced air through the channels 22. and 8 enters the equalizing part of the crane. The charge pressure in the surge tank is maintained at the level of the adjustment of the gearbox 5. The pressure of the equalizer part of the valve acts on the small piston 11 of the switching valve 3. When the valve 14 is leaky, the valve 1 blows air into the atmosphere through the throttle 13 without causing the shift valve to shift to the right.

When braking (figure 2) valve 1 and 2 are de-energized. The valve 14 is open and the surge tank is discharged by the rate of service braking through channels 17 and 18, bay 19, channel 20 and the throttle hole 21.

When the valve 1 is blocked (Fig. 2), the valve 1 is under voltage. The valve 14 is closed. Switch valve 3 is in the right position. In this case, channel 22 is disconnected from channel 8. The channel of the stabilizer 9 is disconnected from the surge chamber. If the valve 15 is loose, the valve 2 air flows into the atmosphere through the valve and the stabilizer hole.
