Protecting grade is IP65, and vibration and impact test meet the requirement of TB/T 3009-2011 4.2.4.4 clause.
When the new-type antiskid valve gear that the present invention relates to uses, when air inlet coil and the aerofluxus coil of solenoid composition are equal
During no-voltage, new-type antiskid valve gear is equivalent to a straight-through pipeline, and the compressed air in train braking pipeline is sent into row
In car checking cylinder, train is braked；When air inlet coil obtains electric, new-type antiskid valve gear is by train braking pipeline and checking cylinder
Between air inlet block, the compressed air in brake piping cannot be introduced into checking cylinder makes checking cylinder be in packing state；When entering
Gas coil and aerofluxus coil all electric time, the air inlet between train braking pipeline and checking cylinder is cut by new-type antiskid valve gear
Disconnected, meanwhile, the path between checking cylinder and ambient atmosphere is connected by new-type antiskid valve gear, the compressed air in checking cylinder is released
Being put in air, the release of train brake brake shoe makes train be in relieved state.
Compared with prior art, the intermediate filter screen using the copper powder of 100 mesh to use sintering process to make can for the present invention
Filter the impurity that particle diameter is more than 0.05mm, when the compressed air containing impurity from air inlet side plate enter after through intermediate filter screen
Time, the impurity in compressed air is filtered by intermediate filter screen, it is impossible to enter the solenoid composition on intermediate and spool valve seat
In, it is ensured that new-type antiskid valve gear normally works in the compressed air containing impurity；Its agent structure is simple, and performance safety can
Leaning on, applied widely, failure rate is low, maintenance cost is few, and life cycle is long, uses environmental friendliness.
