In practical application, after truck vehicle implements braking, when to the lorry fill character and conduct and make, by locomotive room driver
Wind button is filled in operation, and the Brake pipe pressure of the control valve 5, which rises, causes the chamber volume 24 of pilot valve 2 to connect with the control room 51
It is logical, the pressure of the control room 51 is reduced, the pressure that the lorry is eliminated automatically is overcharged, and the lorry is reached automatic alleviation.
Specifically, after truck vehicle implements braking, when to the lorry fill character and conduct and make, the truck vehicle may
In following two states；
The first state, when the pressure of the control room 51 is not more than 300KPa, the right side control room of diaphragm plate 22 in pilot valve 2
51 pressure is suitable with the pressure of left hand brake pipe 52.Now, the first valve 23 is opened, and the second valve 25 is closed, pilot valve 2
Chamber volume 24 is connected with control room 51.
Second of state, when the pressure of the control room 51 is more than 300KPa, the right side control room 51 of diaphragm plate 22 in pilot valve 2
Pressure be more than left hand brake pipe 52 pressure.Now, the first valve 23 is closed, and the second valve 25 is opened, the volume of pilot valve 2
Room 24 and atmosphere.
Therefore, when truck vehicle is in the first state, when to the lorry fill character and conduct and make, operated by trainman
Fill after wind button, the pressure of brake pipe 52 is begun to ramp up, rise with the pressure of brake pipe 52, the left side of diaphragm plate 22 in pilot valve 2
Pressure increase, diaphragm plate 22 is moved to the right, the first valve 23 is opened, the second valve 25 is closed, the chamber volume 24 of pilot valve 2 with
Control room 51 is connected, the pressure reduction in control room 51, truck vehicle is not at pressure overcharging state, is reached automatic alleviation.
When truck vehicle is in second state, the lorry is carried out filling character and conduct when making, operated by trainman and fill wind
After button, the pressure of brake pipe 52 is begun to ramp up, and is risen with the pressure of brake pipe 52, the left pressure of diaphragm plate 22 in pilot valve 2
Increase, makes diaphragm plate 22 move to the right, finally opens the first valve 23, the second valve 25 is closed；The volume of final pilot valve 2
Room 24 is connected with control room 51.Due to total measurement (volume) increase so that the pressure reduction in control room 51, truck vehicle is set to be not at pressure
Power overcharging state, reaches automatic alleviation.
The elimination lorry that the present invention is provided overcharges the device of pressure, can change the appearance of control room automatically according to actual conditions
Product, when controlling chamber pressure excessive, the pressure of control room can be reduced automatically, the purpose alleviated automatically is reached.
When the locomotive that such as air feed pressure is 550KPa is replaced by the locomotive that air feed pressure is 500KPa, pass through locomotive room department
Machine is operated, and the volume of control room can increase automatically, is caused control room pressure reduction, truck vehicle is reached what is alleviated automatically
It is required that.Intensity of workers is so not only reduced, the time of stoppage of vehicle is reduced, and avoided due to work people
The carelessness of member, is likely to result in the situation that vehicle is not alleviated and band-type brake is slided.It is easy to realize vehicle remoulding simultaneously, ensure that goods
The normal safe operation of car.
The foregoing is only a preferred embodiment of the present invention, is not intended to limit the scope of the present invention, it is all
Any modifications, equivalent substitutions and improvements made within the spirit and principles in the present invention etc., should be included in the protection of the present invention
Within the scope of.
