Description
Technical field
The utility model belongs to rail vehicle braking system technical field, and more particularly to a kind of rail vehicle cutout cock is total
Into.
Background technology
Rail vehicle cutout cock assembly is used to discharge the compressed air in checking cylinder manually on rail traffic vehicles, from
And alleviate vehicle braking, a general cutout cock is used for a pair of checking cylinders of hand relieving.
Existing rail vehicle cutout cock assembly includes cutout cock and a plurality of pipeline, and wherein cutout cock is provided with air inlet
Mouth, exhaust outlet and gas outlet.The cutout cock is tubular type cutout cock.The air inlet of tubular type cutout cock passes through pipeline and system
The outlet of dynamic control unit is connected, and the gas outlet of tubular type cutout cock is connected by pipeline with checking cylinder.In rail vehicle
During braking, the air inlet of cutout cock communicates with gas outlet, and braking pressure is entered by the outlet of brak control unit blocks plug
The air inlet of door, then enter checking cylinder from the gas outlet of cutout cock.When cutout cock blocks, the air inlet of cutout cock with
Path between gas outlet is truncated, and the exhaust outlet of cutout cock communicates with gas outlet, and the compressed gas in checking cylinder is led to successively
Gas outlet and the exhaust outlet discharge of cutout cock are crossed, so as to realize vehicle release of brake.
Existing rail vehicle cutout cock assembly has the disadvantages that：
First, for ease of operation, cutout cock is arranged in guest room, and brak control unit and checking cylinder are arranged in
Vehicle bottom, thus each pipeline that cutout cock assembly is used is needed through car body floor, it is therefore desirable to opened on car body floor
If multiple through holes.Because each through hole is required to do encapsulation process, thus it is cumbersome for installation, workload is big, vehicle sealing effectiveness
Difference.
Second, between the outlet of the air inlet and brak control unit of each tubular type cutout cock, tubular type cutout cock
Gas outlet and checking cylinder between be required to connect using pipeline, and multiple tubular type cutout cocks are typically provided on rail vehicle,
Thus in-car pipeline is various, and pipeline arrangement is sufficiently complex, and space-consuming is larger, the design to in-car other systems bring it is many not
Just.
3rd, because the exhaust outlet of tubular type cutout cock is smaller, thus road can not be taken over so that outlet is led into underbody, caused
Directly compressed air can only be come in compartment, internal car noise is larger.
The content of the invention
Existing rail vehicle cutout cock assembly includes tubular type cutout cock and a plurality of pipeline, and installation is inconvenient, and vehicle is close
It is poor to seal effect；In-car pipeline arrangement is complicated, and space-consuming is big, and internal car noise is big.The purpose of this utility model is, for above-mentioned
The deficiencies in the prior art, there is provided a kind of rail vehicle cutout cock assembly improved, simple in construction, easy for installation, vehicle is close

Located at gas circuit plate top surface, gas path plate is fixedly arranged on car body floor, and the bottom surface of gas path plate communicates with the external world, and gas path plate bottom surface is provided with the
One stomata and the second stomata；The outlet of brak control unit is communicated by the first stomata with air inlet, and gas outlet passes through the second gas
Hole communicates with checking cylinder.
By said structure, the tubular type cutout cock on original car is replaced with into board-like cutout cock, by original car
Pipeline replaces with gas path plate, and so as to which board-like cutout cock is directly mounted on gas path plate, brak control unit and checking cylinder only need
The corresponding stomata in gas path plate bottom surface is connected with pipeline.It can be seen that pipeline is without needing guiding through vehicle floor, only need to be to gas path plate one at
Encapsulation process is carried out, reduces the difficulty of vehicle sealing, easy for installation, vehicle good sealing effect.Simultaneously as cutout cock is straight
Connect on gas path plate, need not be connected between board-like cutout cock and gas path plate by pipeline, therefore in-car space-consuming
It is small, without considering in-car pipeline Layout Problem and not interfering with the design and installation of in-car other systems.
Further, the gas path plate bottom surface is additionally provided with the 3rd stomata, and exhaust outlet is communicated by the 3rd stomata with the external world.
,, can because checking cylinder, gas outlet connect with the 3rd stomata when board-like cutout cock blocks by said structure
So that the compressed air in checking cylinder is drained into outside car by the 3rd stomata, reduce internal car noise.
Further, the feedback of status end on the cutout cock electrically connects with wagon control management system.
By said structure, the open and-shut mode of board-like cutout cock can be fed back to wagon control management by electric signal
System, there is provided system works intelligent and maintainable.
Further, the gas circuit plate top surface is provided with brake pressure test mouth, the gas outlet and the second stomata with system
Dynamic pressure test mouth is connected.
Further, the gas circuit plate top surface is provided with total wind pressure test mouth, and the gas path plate bottom surface is provided with and total blast
Total wind pressure entrance that power test mouth communicates, total wind pressure entrance are connected with total wind pressure bellows.
By said structure, mouth can be tested by brake pressure and detects brake pressure, mouth inspection is tested by total wind pressure
Total wind pressure is surveyed, operation under avoiding into driving, reduces working strength and danger.
Compared with prior art, the utility model is simple in construction, easy for installation, vehicle good sealing effect, occupies little space,
Internal car noise is small.
