Embodiment Construction
[0026] Such as figure 1 As shown, the brake device in one embodiment of the present invention includes a distribution valve, a brake cylinder, a train pipe, a main air pipe, a pressure reducing valve 1, a first valve 2, a one-way valve 3, a solenoid valve 4, and a reversing valve 5. Pressure switch 6 and dust filter 7. The distribution valve comprises a first output port 11 and a second output port 12 .
[0027] Such as Figure 1 to Figure 3 As shown, the first valve 2 includes a first channel a, a second channel b, a third channel c and a control switch 15, and the control switch 15 has a first position and a second position. Such as figure 2 As shown, when the control switch 15 is in the first position, both the first channel a and the third channel c are turned off, and the second channel b is turned on. Such as image 3 As shown, when the control switch 15 is in the second position, both the first channel a and the third channel c are turned on, and the second channe...

The invention discloses a locomotive, a braking device of a brake of the locomotive and a control method, and relates to the technical field of braking of locomotives. By designing electric control of the first valve, rapid switching between a normal operation mode and a fireless mode is achieved, and operation is easy and convenient. The pressure reducing valve is used for replacing the safety valve, the fireless return pressure in the fireless mode can be limited, the pressure can be adjusted according to the working condition, the requirements of different fireless working conditions are met, meanwhile, the design that the failure rate of the safety valve is high is avoided, and the reliability of a brake system is improved when the brake system is fireless for a long time. And designing a fireless mode of the compressor in a working state and a control method thereof. Single-point faults caused by a single one-way valve can be effectively reduced, the problem that a train is relieved due to the fact that main air flows back to a train pipe under special working conditions is effectively solved, and operation convenience and reliability of a braking system are improved.
Description
technical field [0001] The invention relates to the technical field of braking of a locomotive, in particular to a braking device and a control method for a locomotive and a braking machine thereof. Background technique [0002] At present, in the braking system of rolling stock, most of them are equipped with no-fire loopback mode, which is to ensure that the braking system (generally pneumatic drive) of the rolling stock can be normally used by the connected vehicle (locomotive) during the railway transportation and rescue process. ) to implement braking and release simultaneously. The safety, operability, convenience and other performance indicators of the brake system are directly related to the normal use of the brake system of the connected trailer. Therefore, the defects in the no-fire loopback mode of the braking system will pose a serious threat to the safety of the rolling stock. [0003] At present, when the brake is returned without fire, it is necessary to swi...
