This invention relates to railway transport.

The aim of the invention is to increase the reliability of action.

The drawing shows a disengaging valve, a general view.

The release valve includes a housing 1 with a stepped cavity 2 having a cylindrical surface 3. A step cavity 2 is connected to an inlet channel 4 connected to a source of compressed air, for example, to a brake line (not shown). The output channel 5 is connected to a consumer of compressed air, for example with an air distributor (not shown). The release valve has a locking device consisting of a sleeve 6, a sensing spring force 7 and having an internal shoulder 8, and a shoulder 9 made on the stem 10 .. The latter interacts with the cam element 11 of the crane control handle 12. Burt

13, which is in contact with the cylindrical surface 3 of the cavity 2, in the closed position of the crane (as shown in the drawing), the contact is in the closed position of the crane, the sleeve 6 under the force of the spring 7 occupies the uppermost position, abutting the housing 1 and blocking the output channel 5, the shoulder 9 of the rod 10 also occupies the highest position. The annular seal 13 overlaps the message brake line with the air distributor.

To communicate the air distributor with the brake line, the release valve is set to the open position at which the handle 12 with the cam element. 11 is rotated by 90. The burt 9 of the rod 10 is lowered under the force of the spring 17 and compressed air in the cavity 2. The ring seal 13 moves first along the cylindrical surface 3 and then along the inner surface 15 of the sleeve 6, which prevents it from everting out of the socket. After the o-ring 13 moves

9 is provided with an annular ear-25 on the inner surface 15 of the sleeve.

6, the shoulder 9 begins to interact with the sleeve 6 through its shoulder 8. The sleeve 6, together with the shoulder 9, is lowered in; - the lowest position to the full

it is an edge 14. Inside the opening of the output channel 5. The atmosphere 15 of the sleeve 6 has a diameter equal to the smaller diameter of the stepped cavity 2.

From the butt, i.e. From the extreme upper point 16 of the inner surface 15 of the sleeve 6, the contact of the ring seal 13 begins with the sleeve 6 when the disconnecting valve is opened.

The spring 9 acts on the collar 9.

The stem 10 is made atmospheric hole 18, overlapped by a seal 19.

In the closed position of the crane between the collar 8 of the sleeve 6 and the collar 9 of the stem, a gap is established that is larger than the distance between the edge 14 and the point 16.

Disconnecting crane works as follows.

The ferrule 18 is closed by a seal 19 ..

When it is necessary to close the disengaging valve, the cam element 11 is turned to the closed position with the handle 12. The stem 10 with collar 9 moves upwards. Under the force of the spring 7, the sleeve 6 rises until it resists in the housing 1. Thereafter, the shoulder 9 rises to its edge its upper position. In this case, the annular seal 13 moves from the inner surface 15 of the sleeve 6 to the cylindrical surface 3, only the gap between the sleeve 6 and the housing 1 intersects.

Claims (1)

Invention Formula An uncoupling valve for the brake duct of a railroad vehicle, comprising a housing with a cylindrical stepped cavity, communicated with the inlet and outlet channels and a locking device located in said cavity, having a rod biased with a spring from the inlet side to the cam element of the control handle, the rod being made with collar and groove If the release valve serves to communicate and disconnect the brake line with the air distributor, it is installed in the pipeline connecting the brake line with the air distributor. In this case, the input channel 4 communicates with the brake line, and the output channel 5 - with the air distributor. open the output channel 5. Atmos0 five 0 five The ferrule 18 is closed by a seal 19 .. When it is necessary to close the disengaging valve, the cam element 11 is turned to the closed position with the handle 12. The stem 10 with collar 9 moves upwards. Under the force of the spring 7, the sleeve 6 rises until it stops against the body 1. Thereafter, the shoulder 9 rises to its highest position. In this case, the annular seal 13 moves from the inner surface 15 of the sleeve 6 to the cylindrical surface 3, only the gap between the sleeve 6 and the housing 1 intersects. Invention Formula An uncoupling valve for the brake duct of a railroad vehicle, comprising a housing with a cylindrical stepped cavity, communicated with the inlet and outlet channels and a locking device located in said cavity, having a rod biased with a spring from the side of the inlet channel to the cam element of the handle of control collar and groove 31390100 which has an annular seal on the sleeve with an inner collar, a slide of the locking device, which is tied to the wall of the case due to the fact that, with the aim of overlapping under the action of a spring-loaded reliability the channel, while the inner point in the collar of the stem is full of the diameter of the bushing equal to a smaller cylindrical surface, the diameter of the cylindrical cavity, and the stem is sealed relative to the wall of the bushing of the bushing is part of the cylindrical cavity smaller In this position of the diameter by means of an annular Jupne device, the axial clearance of the intersection placed in the groove to the collar of the rod is larger than its collar, in the part cylindrical the distance between the edge of the seal is larger than the cavity of the element and the end of the sleeve.
