Technical field
The utility model relates to the lorry air diverter valve that a kind of railway vehicle braking is used.
Background technology
The seventies in last century, the U.S. set up the chattering type brake activation valve that quickens commonly used at the emergency portion of lorry air diverter valve (ABD valve), renamed as the ABDW valve.To use the acceleration brake action nineties again always and move in the air diverter valve emergency portion guiding valve, be called the ABDX valve.
The acceleration brake action commonly used of U.S.'s lorry air diverter valve requires locomotive must have the wind of benefit performance, when locomotive is not opened benefit wind performance, to cause that the effect of lorry air diverter valve is unusual, and the GK valve in China's lorry air diverter valve, 103 valves can not adapt to locomotive and mend the wind performance, and therefore most locomotives are not all opened it and mended the wind performance.Also adopt the performance identical will cause that the train braking effect is unusual as China with the acceleration brake action commonly used of U.S. lorry air diverter valve.
The research of China's heavy haul train braking technology is the starting eighties, 120 valves that nineteen ninety-five promotes, accounted for national lorry sum so far more than 50%, main performances such as the service braking velocity of wave of 120 valves, release propagation rate, emergency braking velocity of wave have reached external advanced brake level, facts have proved that these performances can satisfy the requirement of heavy haul transport substantially.
Then design during 120 valves because of considering the shuffling problem with a hundreds of thousands of K (GK) valve, and the trailing weight target only is ten thousand tons, temporarily given up acceleration deceleration and stopping performance commonly used.
Along with the development of China railways heavy haul transport, the lorry air diverter valve also needs to increase the deceleration and stopping performance that quickens commonly used.

The specific embodiment
As shown in Figure 1, a kind of lorry air diverter valve of the utility model, comprise that main valve forms 1, release valve forms 2, intermediate form 3 and emergency valve form 4, main valve form 1 and emergency valve form 4 and be installed on the intermediate composition 3 with quadruplet and two cover double-screw bolts, nut respectively; Release valve is formed 2 usefulness, two cover double-screw bolts, nut is installed on the side mount pad of main valve composition 1, and rubber pad is all arranged between each attachment face; In the main valve composition 1 guiding valve and graduating valve are installed, described guiding valve bottom surface and guiding valve end face are respectively arranged with a plurality of braking hole slots, and described graduating valve is provided with the braking hole slot.
As shown in Figure 2, the braking hole slot of guiding valve described in the utility model bottom surface is arranged as: first row is provided with three hole slots, and the office of being respectively subtracts air-filled pore L5 from left to right, office subtracts contact groove L7 and resistance is adjusted groove ZU; Second series is provided with five hole slots, and the second series hole slot is arranged on the line of centers of guiding valve bottom surface, is respectively brake cylinder air-filled pore f3, brake cylinder hole Z2 from left to right, service lap is stablized hole slot f4, slide valve face air-filled pore L4 and slide valve face deceleration air-filled pore L3; The 3rd row is provided with 4 braking hole slots, is respectively guiding valve place second game from left to right and subtracts hole ju3, guiding valve place first game and subtract hole ju1, guiding valve side opening f7 and quicken to alleviate cylinder charge hole f2.
As shown in Figure 3, each hole slot of guiding valve end face described in the utility model is arranged as: the leftmost side is brake cylinder air-filled pore f3 between two parties, row is followed successively by guiding valve place first game from left to right and subtracts hole ju1 and quicken to alleviate reservoir air-filled pore f2 on the right side, under the right side row from left to right the office of being followed successively by subtract air-filled pore L5 and countercylinder air-filled pore f1.
As shown in Figure 4, graduating valve is provided with graduating valve contact groove L6 under the utility model.
The utility model control cock is lifted on the floor underframe for vehicle with screw bolt and nut by φ 22 holes on four lugs in intermediate top.The utility model lorry air diverter valve has the deceleration and stopping performance that quickens commonly used, and it is commonly used to quicken brake action and realized by guiding valve, each hole slot of graduating valve open and close when the same-action position not.
During the inflation position, the train tube pressure air is inflated to auxiliary reservoir by the slide valve face air-filled pore L4 and the auxiliary reservoir air-filled pore f1 of train pipe through guiding valve.The auxiliary reservoir pressure air is alleviated reservoir air-filled pore f2 through the acceleration on the guiding valve again and is quickened to alleviate the inflation of reservoir air-filled pore to the slide valve seat that quickens to alleviate on the reservoir.
When subtracting for one innings, train tube pressure air train pore on slide valve seat subtracts air-filled pore L5 through office, and again through graduating valve contact groove L6, guiding valve place first game subtracts hole ju1, subtracts the chamber to office, and generation office subtracts effect.
During service application position, train tube pressure air train pore on slide valve seat subtracts air-filled pore L5 through office and subtracts valve braking contact groove with office and communicate.Simultaneously train tube pressure air train pore on slide valve seat also subtracts air-filled pore L5 through office, and graduating valve contact groove L6, guiding valve place first game subtract hole ju1 and guiding valve place second game and subtract hole ju3 and innings subtract the chamber and communicate.The auxiliary reservoir pressure air through guiding valve brake cylinder air-filled pore f3 to brake cylinder.
Owing to moving, graduating valve blocked auxiliary reservoir during the service lap position through the path of brake cylinder air-filled pore f3 to brake cylinder.Train tube pressure air train pore on slide valve seat subtracts air-filled pore L5 through office and continues to keep to communicate with the braking contact groove.The train tube pressure air slows down reservoir air-filled pore f2 and communicates with auxiliary reservoir through slide valve face air-filled pore L4 (φ 0.2 pressurize stable hole), acceleration through the train pore.
The utility model lorry air diverter valve is for adapting to having of the China's national situation needs lorry air diverter valve that quickens deceleration and stopping performance commonly used, and its deceleration and stopping performance that quickens commonly used meets the following conditions:
1, not only has the deceleration and stopping performance that quickens commonly used, but also China's national situation must can be fit to, the lorry air diverter valve that has just increased behind the acceleration deceleration and stopping performance commonly used should adapt in pressure conservation condition (tonifying Qi) utilization down, can use with GK valve, 103 valves, 120 valve shufflings under the pressure conservation condition not having again.
2, for ease of maintenance, no longer increase parts on the structure, still reaching increases the purpose of quickening deceleration and stopping performance commonly used.
The utility model is not limited to above-mentioned preferred forms, and other any identical with the utility model or akin products that anyone draws under enlightenment of the present utility model all drop within the protection domain of the present utility model.
