(4) according to the stressing conditions of the pedal of brake valve assembly and the rational position that the brake valve push rod stops in valve, selecting diameter is 200mm, the movement length of push rod is the cylinder 2 of 100mm, in order to make exerting pressure of pedal adjustable, add the air inlet that a pressure regulator valve 6 is regulated cylinder 2 at the air intake opening of cylinder 2.
(5) operation of switch board: press starting switch, k1 gets electric, the adhesive of k1 normally opened contact, and normally closed contact disconnects, k1 finishes self-locking, and simultaneity factor is descending, and kt1 starts, the time-delay beginning, after time-delay finished, the kt1 contact was often opened and is become normally closed, and normally closed change is often opened, the k1 dead electricity, the contact action is opposite, and k2 gets electric, and self-locking is finished in the contact action, kt2 starts time-delay and system uplink simultaneously, after time-delay finishes, and the action of kt2 contact, k2 dead electricity, the contact action is opposite, and while k1 gets electric, finishes self-locking, periodic duty.Press shutdown switch, the control system dead electricity quits work.
(6) for the rigging position that can simulate car load and the reliability of brake valve assembly performance, connect brake lamp during test, insert pressurized air and tensimeter at air intake opening and gas outlet, insert pressure regulator valve at air intake opening simultaneously, according to different brake valve assembly requirements, whether whether observing brake lamp can operate as normal, leak gas in two total coelosis of tensimeters contrast brake valve with air intake opening and gas outlet.
(7) operate more humanely, more attractive in appearance for testing table, made one and highly be the work top of 800mm.Stabilized voltage supply 9 and switch board 8 are put in worktable 5 bottoms.
Advantage of the present utility model is: cost is low, the test period is short, has improved complete vehicle quality.At rigging position and usability the testing table that brake valve assembly reliability tested of experiment lab simulation brake valve assembly in car load, during it can satisfy, the heavily test of auto exhaust brake valve assembly reliability, and safe, simple to operate, versatility is good, can shorten the test period, practical.
