Problems solved by technology
The original method needs to disassemble the mechanism indicator valve for detection. Since disassembling the valve requires dismantling most of the components of the entire coupler system and the operation is cumbersome, it is necessary to invent a method that does not need to disassemble the mechanism indicator valve to detect its function on the train.

Embodiment Construction
[0015] refer to figure 1 , figure 2 , image 3 , Calibration gauge 9, hook plate 3, block 4, electrical connector 1, knuckle 2, copper core 5 in the main air duct valve, lock rod 6, mechanism indicator valve 7, manual unhook handle 8;
[0016] testing method:
[0017] 1. Confirm that the components and valves of the coupler system are in normal working condition.
[0018] 2. Pull the manual uncoupling handle 8, and push the lock lever 6 backward at the same time, so that the lock lever 6 is released, and the knuckle 2 is stretched out to simulate the mechanical coupling of the coupler.
[0019] 3. Pull the uncoupling handle 8 until the 15mm end of the calibration gauge 9 can be installed between the hook plate 3 and the stopper 4, supply compressed air to the coupler system, and push the copper core 5 in the valve of the main air duct. At this time, the electric Connector 1 cannot protrude, if it protrudes, the mechanism indicator valve needs to be adjusted or replaced. ...

The invention provides a method for testing functions of a coupler mechanism indication valve, and the method comprises the following steps of: firstly determining that each component and valve of a coupler system are in a normal working state; releasing a lock rod, extending a coupler knuckle, pulling a manual uncoupling handle to separate a coupler plate and a chock block, inserting a reference gauge between the coupler plate and the chock block, pressing an inner copper core of a total duct valve, and verifying whether the mechanism indication valve works normally or not by checking whether an electric connector 1 extends out or not. The method provided by the invention be used for checking whether the electric connector extends out to verify whether functions of the mechanism indication valve are normal or not through imitating coupling of vehicle machineries and imitating the rotation angle of the mechanism indication valve by the reference gauge, therefore actual coupling of two trains is unnecessary, manpower and material resources are greatly saved, the operations are simple and convenient, the practicability is strong, and the working efficiency is greatly improved.
Description
technical field [0001] The invention belongs to the technical field of vehicle debugging technology, and relates to a process method for detecting the function of an indicator valve of a coupler mechanism. Background technique [0002] In the process of connecting and unhooking the automatic couplers of the two trains of the EMU, the action of the corresponding mechanical structure drives the cam rotation of the mechanism indicating valve, and the rotation of the mechanism indicating valve cam drives the corresponding air circuit inside the coupler system, thereby driving the extension of the electrical connector. In this way, the connection of the electrical systems of the two trains has been realized. The original method needs to disassemble the mechanism indicator valve for detection. Since disassembling the valve requires dismantling most of the components of the entire coupler system and the operation is cumbersome, it is necessary to invent a method that does not need ...
