The dual pipe air supply device of prior art adopts tubular type mounting means, is namely coupled together by each valve steel pipe according to principle of work, sees Fig. 1.When locomotive needs to passenger vehicle air feed, by cock A close, cock B opens, total wind through cock B, reducing valve, boiler check valve, from d mouth supply vehicle; When locomotive double heading uses, opened by cock A, cock B closes, and total wind directly arrives being communicated with of d mouth and the total reservoir of multi-locomotive through cock A.This scheme is owing to being adopt tubular type mounting structure, and volume is large, and Heavy Weight, is unfavorable for that locomotive space mounting is arranged.In addition, owing to adopting the switching between two cock control 600kPa and 900kPa, during bus attendant blocked operation, need operation two cocks just can complete switching, occur the situation that operation is disorderly sometimes.
Utility model content
The purpose of this utility model overcomes the deficiency of above-mentioned prior art exactly, provides a kind of railway locomotive dual pipe air supply device.
The purpose of this utility model is achieved in that a kind of railway locomotive dual pipe air supply device, passenger vehicle air feed path and heavily UNICOM road also connect, reducing valve and boiler check valve are serially connected in passenger vehicle air feed path, it is characterized in that total wind entrance arranges the threeway cock that has a, b, c tri-ports, the a mouth of threeway cock is connected to total wind entrance, c mouth is connected to the input end of passenger vehicle air feed path, the mouth of b mouth and air feed path is jointly connected to total wind and exports, pull the valve handle of threeway cock, the conversion between passenger vehicle air feed path and heavy UNICOM road can be realized.
In order to better realize the purpose of this utility model, the Interface integration of the boiler check valve of described total wind entrance, the outlet of total wind, passenger vehicle air feed path and heavy UNICOM road and threeway cock, reducing valve is on one piece of integrated air board.
In order to better realize the purpose of this utility model, described integrated air board is made up of the stacked welding of two-layer aluminium alloy plate, aluminium alloy plate side, upper strata forms gas circuit by air drain, opposite side is provided with valve class bolt interface corresponding to air drain gas circuit, the air drain tight weld on lower floor's aluminium alloy plate and upper strata aluminium alloy plate.
The technical solution of the utility model, adopts a threeway cock, and make gas circuit blocked operation become very simple, and can not make mistakes, apparatus structure becomes compact; Adopt integrated air board, achieve modular design, there is little, the lightweight feature of volume, as long as total blast main is connected to the control that corresponding interface can realize export wind pressure, without the need to some independent valve bodies are connected by many pipelines.Structure is simple, and inspection and maintenance is also very convenient.
