Abstract

Invention m. used to drain condensate from the air receivers of the vehicle brake system. The invention improves reliability. Compressed air from the receiver 10 enters the collecting cavity 16 and acts on the membrane 13 and the locking member 5. Compressed air through the pressure regulator (RD) 11 enters the control cavity 15. At the same time, the rod 12 is in the extreme right position. The exhaust valve is closed, in the area 16 there is an accumulation of condensate. When the pressure in the receiver 10 reaches a value equal to the upper limit of the RD 11, the latter is triggered, the pressure at the entrance to the cavity 15 drops to zero. By overpressure in the cavity 16, the perforated rod (PN) 12 is moved to the left. The upper end 17 of the stem 6 extends from the opening of the PN 12. In this case, the stem 6 is deflected to the side, causing the shut-off member 5 to open up the outlet 2. The condensate is ejected from the housing 1.

When the HSH 12 is displaced, the upper end 17 of the rod 6 enters the hole PN 12, the rod 6 is raised and under the action of the spring 4 the locking member 5 sits on the saddle 3, stopping the condensate drain. When pressure is reached

The invention relates to devices for removing condensate from pneumatic systems, mainly from air receivers of a vehicle's braking system.

The purpose of the invention is to increase reliability.

The drawing shows a condensate trap, a general view.

The steam trap for pneumatic systems comprises a housing 1 with an outlet 2 in the lower part, in which are placed the saddle 3 of the exhaust valve, spring-loaded 4 a shut-off member 5 with a vertical stem 6. At the lower end of the stem 6 there is a ring 7 for manual valve actuation. Crush 8 is provided with a pipe 9 connected to a receiver 10 having a pressure regulator 11. The housing 1 contains a perforated horizontal movable rod 12 connected to a membrane 13 installed between the housing 1 and the roof 14. The membrane 13 divides the housing 1 into control and team cavities 15 and 16, respectively. The cavity 15 is connected to the pressure regulator 11, and the cavity 16 to the receiver 10. The spring 4 in the closed position of the valve presses the locking member 5 to the seat 3, while the upper end 1.7 of the rod 6 is placed in one of the holes in the perforated rod 12.

At the initial moment of operation of the pneumatic system, compressed air from the receiver 10 enters the cavity 16 and acts on the diaphragm 13 and the shut-off organ 5. Compressed air through the pressure regulator 11 enters the cavity 15, and since the air pressure is greater than the pressure in the receiver 12 is at the extreme right. The exhaust valve is closed.

the receiver 10 of a value equal to the lower limit of regulation, the RD 11 is activated, the pressure in the cavity 15 increases, which leads to the reverse movement of the PN 12 to the right position -. 1 il.

Condensate is accumulated in cavity 16. When the pressure in the receiver 10 reaches a value equal to the upper limit of the pressure regulator 11, the latter is triggered, the pressure at the entrance to the cavity 15 drops to zero. By overpressure in the cavity 16, the perforated rod 12 is moved to the left. The upper end 17 of the stem 6 exits the hole of the perforated stem 12, the stem 6 is deflected, as a result of which the locking member 5 opens the outlet opening. 2. By pressure in cavity 16, condensate is ejected from housing 1. With further movement of the perforated rod 12, the upper end 17 of the rod 6 falls into one of the holes of the perforated rod 12, the rod 6 is straightened, and under the action of the spring 4, the valve body 5 sits on the saddle 3, the condensate drain is stopped. When pressure is reached in receiver 10

value equal to the lower limit of regulation, the pressure regulator 11 is activated, the pressure in the cavity 15 increases, which leads to the reverse movement of the perforated rod 12 (to the right). When the perforated stem 12 is moved, the upper end 17 leaves the position fixed in one of the holes, deflects, the locking member 5 opens the hole 2, and condensate is released.

35 When the perforated stem 12 reaches its initial position, the upper end 17 of the stem 6 falls into one of the holes of the stem 12, straightens, and the locking member 5 sits on the saddle 3.

With further operation of the pressure regulator 11 as a result of the flow of air from the receiver 10, the condensate drain cycles are repeated.
