Train braking cylinder 20, for exporting braking cylinder pressure.
Braking pre-control pressure transmission pipe indirectly, is used for transmission and brakes pre- governor pressure indirectly；
The train braking cylinder 20 can be used as train wind regime and provides required compressed air for train braking, and will provide
The pressure that compressed air has is used as braking cylinder pressure.The braking cylinder pressure of output is really being used for train braking
When, it is also necessary to pass through a series of processing.Equally, the pre- governor pressure of braking indirectly for braking the transmission of pre-control pressure transmission pipe indirectly
It is to be obtained after a series of processing, specifically how obtains this and brake pre- governor pressure indirectly, according to different automobile types, operating condition institute
The difference that need, function stress can have various ways, lower according to the actual situation can carry out flexible choice.How train is being realized
Braking aspect, braking cylinder pressure is in the pre- governor pressure of straight braking obtained after pressure control device 310 and braking indirectly
The pre- governor pressure of braking indirectly that pre-control pressure transmission pipe provides can undertake train braking effect under emergency brake modes.
Two-way valve 30, including two input terminals and an output end, first input end 31 are connected by control piper and are arranged
Vehicle brakes cylinder 20, and the second input terminal 32 connects the output end of braking pre-control pressure transmission pipe indirectly, is arranged on control piper
There is pressure control device 310, for pre- in the pre- governor pressure of straight braking obtained by pressure control device 310 and indirectly braking
Biggish pressure is selected to be exported between governor pressure.
The present invention is using two-way valve 30 as the selection pre- governor pressure of straight braking under emergency brake modes and braking indirectly
The working principle of selection device of one of them in pre- governor pressure with larger pressure, the two-way valve 30 is similar to tug-of-war, such as Fig. 1
It is shown, first input end 31 input pressure mutually compared with the pressure that the second input terminal 32 inputs, wherein it is biggish that
A " winning ", and as the final output pressure transmission of the two-way valve 30 to subsequent device.Why existed using two-way valve 30
The pre- governor pressure of straight braking and braking indirectly is selected between pre- governor pressure, is for train security consideration, in each function machine
Structure is required there are redundancy protecting, if only with all the way and occur it is abnormal if be likely to result in unpredictable serious consequence, and
Using two different pressure treatment modes, being likely to be obtained is two pressure of different sizes, if one of processing mode
There is exception, the normal work of follow-up equipment can be still realized using the two-way valve 30.
Relay valve 40 exports brake-cylinder pressure, including four pressure inputs and one for adjusting train braking pressure
Pressure output end, first pressure input terminal 41 and second pressure input terminal 42 are respectively base control pressure input and height
Voltage-controlled pressing pressure input terminal, first pressure input terminal 41 and second pressure input terminal 42 connect two-way valve 30 in parallel
The parallel pipeline of output end, second pressure input terminal 42 is equipped with solenoid valve 421；Its third pressure input 43 is braking cylinder
Pressure input connects train braking cylinder 20；Its 4th pressure input 44 is load-carrying pressure input, connects load-carrying pressure
Feedback device 10；
The relay valve 40 is tied by four input terminals, while by most four different input pressures using the mechanical of itself
Structure is adjusted train braking pressure, finally to input the checking cylinder pressure obtained after adjustment to the brake actuator of train
Power.Wherein, by base control pressure input to relay valve 40 input first control pressure, by high-low pressure control pressure it is defeated
Enter end to the input of relay valve 40 second control pressure, why there are two different control pressure inputs, it is intended to according to column
The difference of vehicle actual travel speed judges whether to input the second control pressure to relay valve 40, to realize according to train driving speed
The difference of degree is adjusted the finally obtained brake-cylinder pressure of relay valve 40.As shown in Figure 1, pressure input is controlled based on
First pressure input terminal 41 be in long logical state, and in the second pressure input terminal 42 for high-low pressure control pressure input
It is then provided with solenoid valve 421 on gas piping and is used to control whether to input the second control pressure to relay valve 40.
The difference of train under high-speed travel state and low-speed running state due to travel speed, wheel and interorbital
Significant change can occur for existing adhesion, and adhesion when running at high speed between train wheel track can be significantly less than when running at a low speed
Adhesion between train wheel track, if to the train run at high speed apply with the brake force to the train same size run at a low speed,
It is easy because running at high speed when train wheel track between lesser adhesion lead to the unsafe conditions such as wheel lock up occur, therefore purport of the present invention
Utilizing two control pressure inputs, and one of long logical, another obtaining of then passing through that solenoid valve 421 is according to itself
Electricity or power failure state, it is selective that second control pressure is passed through into the second pressure input terminal for high-low pressure control pressure input
42 be transmitted to relay valve 40 carry out brake pressure structure adjusting, with finally realize to when running at high speed train provide one compared with
Small brake force to avoid there are the unsafe conditions such as wheel lock up, and provides a biggish system to train when running at a low speed
Power can preferably ensure the life security of passenger and realize secure parking.
Specifically, the solenoid valve 421 how according to train running speed it is different realize to the second control pressure output with
No control, the following are a kind of implementations, and velocity sensor and one, which is utilized, to be believed according to the real-time speed received
Number brake-cylinder pressure high-low pressure controlled to the solenoid valve 421 adjusts device:
The velocity sensor, for real-time detection train travel speed and send real-time speed signal；
The brake-cylinder pressure high-low pressure adjusts device, is connected with velocity sensor with solenoid valve 421, for receiving in real time
Speed signal simultaneously judges whether that it is in the conductive state to control solenoid valve 421 if being more than more than threshold speed；If not exceeded, then
Control solenoid valve 421 is in off state.
One specific example: when detecting that train current driving speed is more than 255km/h, the solenoid valve 421 is controlled
In power failure state, solenoid valve 421 is connected, to control pressure to the input of relay valve 40 second；When detecting train current driving
When speed is less than 255km/h, controls the solenoid valve 421 and be in obtain electricity condition, solenoid valve 421 ends, not defeated to relay valve 40
Enter the second control pressure.
In the case where a velocity estimated threshold value is arranged, low speed and high speed can be simply divided into, can also be arranged
More velocity estimated threshold values, so that more accurate to present case judgement, control precision is higher, does not do specific limit herein
It is fixed, most suitable number of thresholds can be comprehensively considered and selected in conjunction with other influence factors according to the actual situation.
Further, check valve can also be set and carry out safeguard protection, the input terminal connection relay valve 40 of the check valve

Brake-cylinder pressure should be less than directly being transmitted to the system of relay valve 40 by third pressure input 43 from train braking cylinder 20
Dynamic cylinder pressure, in this case, which is not in working condition, is only being braked as caused by abnormal conditions
, just can be in running order when cylinder pressure is less than the brake-cylinder pressure, to avoid there are residual pressures in checking cylinder pipeline.It is real
In the case of border, only it will appear when passing through third pressure input 43 to be transmitted to the braking cylinder pressure of relay valve 40 is zero, it should
Check valve can just activate in running order, and remaining brake-cylinder pressure in checking cylinder pipeline is oriented to third pressure input
43。
