Description

The proposed device for automatic translation of the handle of an even regulator on a steam train, in the event of a train break, consists of a diaphragm air distributor with two chambers. One of the chambers is constantly in communication with the main air duct, and the other, having a smaller diaphragm, with the main tank and an additional air chamber, as well as with the air cylinder, through the needle valve connected with the diaphragms, during operation of which cylinder the handle of the steam regulator moves in the direction of close.

In FIG. 1 is a schematic view of a device for automatically translating the handle of a steam regulator on a locomotive; Fig. 2 is a vertical section of a diaphragm distribution creator; FIG. 3 is a front view of an arm of a steam regulator with a device for its automatic translation.

On the front plate / locomotive, on the axis | of the handle 3 of the steam regulator, sector 5 is established with a slot, a slider / 5 in which is connected by a leash / 8 to the piston rod of the air cylinder 2. installed near the crane 7 of the driver, and below the crane 8 double ti gi.

In the air distributor 2J, two diaphragms 7 (Fig. 2) are installed, dividing it into two chambers C and D, of which chamber C, with a larger diaphragm, constantly communicates with the main air duct through hole A and tee JO (Fig. 1) , and chamber D, with a smaller diaphragm, is constantly connected through a calibrated opening / 5 and a tee 9 to the main reservoir J9, and through opening B with an additional air chamber 1L

The diaphragms 7 carry the needle valve 5, and the diaphragm with a large area in the chamber C is connected via a lever transmission to the valve J6, which communicates the chamber with the atmosphere. A needle valve fitting 12 is connected to the aforementioned tube 6, on which a tap-switch J4 is connected, which is connected with a driver to the handle of the driver's tap 7 by means of a driver. In the absence of the need to brake the train, the needle valve 5 is in the closed position, since the air pressure is in chamber C, in view of the difference in the diaphragm areas.

will be more than in chamber D; valve 16 will also be closed.

During the train’s derailment and, in general, when the main air duct ruptures, the air comes out of the latter, after which the pressure in chamber C decreases.

Since in chamber D, which is connected to the main air reservoir and additional air chamber, at this moment the pressure is more than in chamber C, diaphragms 7 bend towards the latter and open the needle valve 5. When the diaphragm 7 is moved to the right, a lever transmission valve 16 opens, connecting chamber C with the atmosphere, which contributes to pressure drop in it and opening valve 5 as soon as possible. Air from chamber D through port E and tap-switch J4, always open during train travel, enters pipe b and from air to air cylinders 2 etc., and wherein moves a piston rod which via a lead / 8 to the slider 75 automatically moves the last handle 3 of the steam controller and closes the steam.

During normal train travel during braking as required by the driver, the tap switch M with the driver's handle closes and the compressed air from chamber D under the action of diaphragm 7 and opening valve 5 cannot get into the air cylinder 2.

The subject matter of the invention.

A device for automatic translation of the handle of the steam regulator on a steam engine, characterized in that the operation of the air cylinder for moving the handle is controlled by the diaphragm air distributor 2 / (FNG. 1) having two of which one chamber is permanently connected with the air duct and the other is with a smaller diaphragm (Fig. 2), it is constantly connected with the main reservoir and an additional chamber and can communicate with the cavity of the cylinder that controls the movement of the handle towards the closing through the needle valve 5 ( u. 2).
