Abstract

The invention relates to railway transport and can be used in passenger cars. The aim of the invention is to increase reliability. For this purpose, an alarm device is installed in the line in front of the stop valve, the casing of which is made of a guide sleeve 7 and a head 8, between which a membrane 9 is installed. In the sleeve 7, a pusher 10 is installed, pressed by a spring 13 to the membrane 9 and provided with a contact plate 11, which closes contacts 14 when a pressure of 5 kg / cm ² is reached in cavity 15 connected to the brake line. When the contacts 14 are closed, the lamp on the console lights up, indicating that there is air in the brake line of the car. At lower pressure or overlapped end valves, the lamp does not light up. 2 Il.

FIG. 2

The invention relates to the field of railway transport and can be used on passenger cars,

The goal of isobrogonium is to increase reliability.

Figure 1 shows a diagram of the brake equipment of a car with an alarm; figure 2 - signaling device, section.

The braking equipment of the car consists of a brake line 1 with a terminal. And cranes 2 and stop valves 3, mounted on the offsets of the pipelines 4. Line 1 is connected via pneumatic actuator 5 to the brake cylinder control equipment (not shown). A signaling device 6 is fixed on one of the branches of the pipeline 4, the housing of which consists of a guide sleeve 7 and a head 8. A membrane 9 is placed between the sleeve 7 and the head 8. A pusher 10 made of electrically conductive material and having a contact plate on the shank is movably placed 11. A glass 12, is screwed into the guide sleeve 7. in which a calibrated spring 13 is placed, pressing the pusher 10 against the membrane 9 and two contacts 14 isolated from each other. A cavity 15 is formed in the head 8 above the membrane 9, into which an opening is connected, connected to the pipeline 4, and a shank 16 of the bypass shut-off element 17 enters valve ', pressed to the seat 18 by the spring 19. The cavity of the bypass valve spring 19 is connected to the atmosphere with a calibrated hole 20 with a diameter of 0.5 mm, Contacts 14 are connected to a signal device, for example, a lamp 21.

In the absence (or insufficient pressure, less than 5 kg / cm ² ) of air in the brake line 1, the spring 13, designed for a pressure of 5 kg / cm ² , moves the pusher 10 to the membrane 9, bending it. In this case, the membrane 9 presses on the valve shank 16, compresses the spring 19, tearing off the valve element 17 from the seat 18. As a result, the cavity 15 is connected to the atmosphere through a calibrated hole with a diameter of 0.5 mm. Outflow of air from hole 20 indicates insufficient pressure in line 1.

In this case, the contact plate 11 of the pusher, the body 10 is located at a distance of the pusher 10 from the contact 14 and the lamp 21 on the conductor’s panel does not light up. the wagon. In this case, the departure of the train is prohibited.

When air enters the highway 1 and, accordingly, into the cavity 15 of the indicator 6, there will be a slight bleeding of air into the atmosphere through the hole 20. With increasing pressure, the membrane 9 will bend to the pusher 10, moving the latter to the contacts 14. In this case, the membrane 9 will move away from the shank 16 and the valve element 17 under the influence of the spring 19 will fall on the seat 18, blocking the air outlet through the hole 20. When the air pressure in the cavity reaches 15 to 5 kg / cm ^{2, the} membrane 9 will move the pusher 10 with the plate 11 to the contacts 14, which, when closed, will light the lamp 21, which is information for the conductor about the presence of air in the brake line for normal operation of the braking equipment of the car.

Claims (1)

Claim A signaling device for the state of the pneumatic line, predominantly the brake line of the carriage, comprising a housing in which a membrane is mounted separating the cavities, the first of which is formed above the membrane and communicates with the channel connected to the pneumatic line, and in the second cavity under the membrane there is a spring loaded to the membrane a pusher carrying a contact element for closing height-adjustable contacts installed in the housing under the contact element and electrically connected to the signaling device characterized in that, in order to increase reliability, it is equipped with a valve for communicating the cavity above the membrane with the atmosphere through a calibrated hole, while the valve locking element is spring-loaded to the seat and equipped with a shank for interaction with the center of the membrane. 1884Θ24
