SU16237A1 - Apparatus for using exhaust steam from an automatic brake air pump in feedwater preheater on locomotives - Google Patents

Description

Disposal of exhaust steam from an automatic brake air pump is highly desirable, since this steam, operating without expansion, has an iBbjcoKY effect, contains a large amount of heat that can be used in a feedwater preheater, if installed on a steam train. However, when putting on steam locomotives, exhaust pipe, steam pipe brake riacoca, it is impossible to simply connect the heater to the heater, since in this case, heating the water with the braided steam of the brake pump will be possible when the water heater is working. If the latter does not act, the exhaust pump of the brake will go into the cylinder’s vapor outlet spaces and condense there in large quantities, to avoid which it is necessary to have some device allowing the pumping of the V111HLOPE steam or into the heater when it operates, or into the atmosphere, when it I will stop The use of a three-way crane operated manually by the 1a-machinist cannot be recommended, as it gives an extra handle in the operator's booth, which needs to be paid attention to and need to be remembered why an automatic device is needed, in addition to the machinist's will;

The proposed device uses a spring piston carrying two valves on its stem, which, under the pressure of the hot steam entering the chamber above the piston, open the pipelines connecting the air pump with either the heater in working condition or with the atmosphere inoperative.

The drawing shows a longitudinal section of the device.J

The device consists of a molded body 1 with a screw 3 attached to the non-heating device 2 fixed to the body 1 and having two saddles 4 and 5, for which valves 6 and 7 fixed to the rod 8, 6 and 7, the valve 6 being one with a piston 9. A cavity 10 above the latter is bounded on top by a lid 11 having an opening 12 for a tube connecting the cavity 10 with a tube of fresh steam supplied to the steam cylinder of the feedwater preheater. Under the piston 9, there is a spring 13, which tends to lift it and slam it

valve 7 If the feedwater heater is operating, the cavity 10 is filled with fresh steam, due to the fact that it is connected to the pipe supplying steam to the heater pump. This steam presses on the piston 9 and forces valve 6 to sit on its saddle 4. Then the exhaust air braking steam supplied to the device through pipe 14 will pass through the open valve 7 and lip 15 to the pipe supplying steam to the engine feed water preheater.

If the heater does not work, then in the cavity 10 above the piston 9 there will be atmospheric pressure and under the action of the springs: 13 Valve 7 will press to its seat 5. Then the pus vapor of the air pump of the brake will pass through the open valve 6 to the nipple 16 and further along the pipe, attached to it, to the atmosphere. The water condensing under the piston 9 can flow down through the channels 17 and 18 and be carried away to the exhaust. Thus, the proposed device will act automatically, besides the will of the driver.; I,

The subject of the patent.

 A device for use in exhaust steam from an air brake Hacocci in the feed water heater on steam locomotives, characterized by -. the use of a spring piston 9 ,. valves 6 and 7, bearing a stem, supplied under pressure through aperture 12 to chamber 10, / above the piston to report opening valve 7, duct 14 of exhaust steam from an air pump with pipeline 15 for supplying it to the heater, while idle state piston 9 by means of spring. The conductor 13 serves to sorb the pipeline 14 through the valve 6c with the pipeline 16, which discharges the exhaust steam. in atmosphere.
