Abstract
The invention discloses a method for detecting the function of an altitude valve of a motor train unit. An air spring is inflated and exhausted by the arrangement of a valve, a pressure gauge and a joint at a pressure detection port of the air spring, so that a train body is driven to ascend and descend to implementation of the action of the altitude valve; and therefore, the function of the altitude valve is detected. A valve rod of the altitude valve is not required to be detached, so that a phenomenon that a screw for fixing the valve rod is broken due to frequent detachment is avoided; and the method is easy to operate, and the manufacturing cost is saved.
Description
Technical field
The invention belongs to vehicle testing and measuring technology technical field, relate to a kind of process of EMU altitude valve Function detection.
Background technology
In CRH5 EMUs, in order to make vehicle operating steady, AIRMATIC Dual Control is installed on bogie, in system, altitude valve is according to different inflation and the exhausts that drive both sides air spring of vehicle both sides height.Original technology adopts and pulls down and move up and down altitude valve valve rod, and detects by tensimeter the function that relevant pressure is checked altitude valve, complicated operation, and due to frequent dismounting, cause the fixing screw rod of valve rod to fracture, increase manufacturing cost.
Summary of the invention
Technical matters to be solved by this invention is to provide and a kind ofly without dismounting height valve rod, can completes the method to altitude valve Function detection, has avoided frequent dismounting to cause the fixing screw rod of valve rod to fracture, easy and simple to handle, reduces manufacturing cost.
For solving the problems of the technologies described above, the invention provides a kind of detection method of motor train unit altitude valve function, it is characterized in that comprising the following steps:
1, at air spring pressure detection mouth place by threeway Bonding pressure table, triplate line valve and joint, to air-supply pipeline, provide pressurized air, open air-supply pipeline valve, triplate line valve is in disconnect position, treats that air spring compressed air is stable;
2, block air-supply pipeline valve, open triplate line valve, the air spring compressed air being arranged on bogie is discharged by joint, car body falls with air spring Bas Discharged, the altitude valve that drive is installed on car body moves down, and makes angle between the height valve rod of altitude valve and altitude valve operating rod be less than 90 degree;
3, block triplate line valve, open air-supply pipeline valve, altitude valve is inflated to air spring, by tensimeter, monitors air spring pressure, pressure continue to rise until between height valve rod and altitude valve operating rod angle equal 90 degree and stop inflating, now illustrate that altitude valve aerification function is normal;
4, block air-supply pipeline valve, joint is connected with workshop wind regime, open triplate line valve, by tensimeter, show air spring pressure rise, car body rises, and between the height valve rod of drive altitude valve and altitude valve operating rod, angle is greater than 90 degree;
5, block triplate line valve, altitude valve continues exhaust by air spring Bas Discharged, until angle equals 90 degree and stops between height valve rod and altitude valve operating rod, by tensimeter, checks that air spring pressure no longer declines, and illustrates that altitude valve degassing function is normal.
The present invention realizes the inflation of air spring and exhaust by be used in conjunction with valve, tensimeter, joint at air spring pressure detection mouth place, with the rise and fall of motor vehicles bodies, realizes the action of altitude valve, thus the function of checking altitude valve.Without dismounting altitude valve valve rod, avoided frequent dismounting to cause the fixing screw rod of valve rod to fracture, easy and simple to handle, save manufacturing cost.
Accompanying drawing explanation
Accompanying drawing is altitude valve Function detection schematic diagram.
Embodiment
Referring to accompanying drawing, detection method of the present invention comprises the following steps:
1, at air spring pressure detection mouth 8 places by threeway 5 Bonding pressure table 4 valve 6 and joints 7, pressurized air is provided to air-supply pipeline 2, open valve 3, valve 6, in disconnect position, treats that air spring 12 compressed airs are stable;
2, cut-out cock 3, open valve 6, air spring 12 compressed airs that are arranged on bogie 13 are discharged by joint 7, car body 1 falls with air spring Bas Discharged, the altitude valve that drive is installed on car body moves down, and makes angle between the height valve rod 10 of altitude valve 9 and altitude valve operating rod 11 be less than 90 degree;
3, cut-out cock 6, open valve 3, altitude valve is inflated to air spring, by tensimeter 4 monitoring air spring 12 pressure, pressure continue to rise until between height valve rod 10 and altitude valve operating rod 11 angle equal 90 degree and stop inflating, now illustrate that altitude valve aerification function is normal;
4, cut-out cock 3, and joint 7 is connected with workshop wind regime, open valve 6, by tensimeter 4, show air spring 12 pressure rises, and car body 1 rises, and between the height valve rod 10 of drive altitude valve 9 and altitude valve operating rod 11, angle is greater than 90 degree;
5, cut-out cock 6, and altitude valve continues exhaust by air spring 12 Bas Dischargeds, until angle equals 90 degree and stops between height valve rod 10 and altitude valve operating rod 11, by tensimeter, check that air spring 12 pressure no longer decline, and illustrate that altitude valve degassing function is normal.
