SU63389A1 - Adaptation to flue gas cranes, such as Everlasting, to prevent water from entering the muffler when the crane is not operating - Google Patents

Description

At present, steam locomotive boiler blowing on the run is used. In this case, there are cases of burns Blown out "by the water of passengers and attendants, as well as deterioration of painting cars and tenders.

The use of silencers does not give positive results, since a silencer that works well in warm time freezes in winter. This is because Everlasting faucets have a small water pass. A stack through a long pipe silencer, water freezes at low temperatures and clogs the cross section of the pipe, making it impossible to blow the boiler.

The device proposed to prevent the silencing of the silencer, shown in the sectional drawing, is made in the drain outlet pipe 3, which is attached to the body 1 of the Everlasting valve on the thread. A branch pipe with a passage in the form of a diffuser 2 is provided at the end with a thread (or flange) 6 for connecting a drain pipe to it, a silencer pipe. From the bottom of the pipe has a drain hole 4. Outside it is covered with insulation 5 and a casing ;. When closed, the crane is small

hot water is passed through the hole 4 to the outside, which prevents the silencer drain pipes from getting into them and eliminates the possibility of freezing.

When drilling the boiler (when the valve is open), due to the conical bore of the OUTPUT cross section of the valve body and the presence of the diffuser 2 in the tapping, in the area of the hole 4, radiation occurs, which creates some suction of air through the hole 4. This avoids contamination of the crew part of the locomotive and eliminates garbage hole 4 slime.

Subject invention

An adaptation to the flue gas valves, for example, such as Everlasting, to prevent water from entering the muffler when the valve is not in operation, characterized in that the connecting pipe of the hub and the valve body with a diffuser through channel in the form of a diffuser is provided at the bottom with an opening for draining the leaking water - during the period between blows and for air leaks during production;

Claims (2)

1. Machine for grinding wire when rewinding from one riot to another using a drum rotating around a wire carrying radially moving grinding wheels, characterized in that brush grinding wheels are used. 2. In the machine tool according to claim 1, the mechanism for automatically feeding the grinding wheels as they wear out, distinguishes with the use of a motorway 93 swung from the drive, acting through the coil spring 0 on the driver disk 72 with pawls 88 coupled to a ratchet wheel 85 connected with spring-loaded the latch 84 with the disc 82 wedged on the grinding wheel feed shaft.
