Brief description
Next elaborate embodiment of the present utility model with reference to the accompanying drawings.There is shown with：
Accompanying drawing 1 illustrates a part for the underframe for vehicle car, together with the draining of the inner space for vehicle car
Drainage equipment.
Specific embodiment
Accompanying drawing illustrates a part for the underframe 10 of vehicle car.This vehicle car is the track including single or multiple compartments
The compartment of vehicle.The upside of underframe 10 is adjacent to the floor area 12 of the inner space 14 of vehicle car.
Underframe 10 has the drainage equipment 16 of the draining for inner space 14 in an integrated fashion.For this reason, this draining sets
Standby 16 entrance areas 18 including constituting on the upside of underframe 10, it is arranged on the opposite of underframe 10 below entrance area 18
Side on and be passed into compartment surrounding 20 in exit region 22, entrance area 18 is flowed with exit region 22
Fluid path 24 and valve 26 that body connects.Entrance area 18 is formed by collecting tank 28, and described collecting tank is used for collecting from interior
The water in portion space 14 is to be constituted (unshowned) water column above valve 26.
Valve 26 has closure means, and described closure means have two can be with (two-way together along mobile route
The obturator 30,32 that the mode of arrow s) movement supports.This two obturator 30,32 is separately fixed at the shaft-like of closure means
An end of load-carrying unit 34 on, described load-carrying unit is from an end stretch of drainage equipment 16 to the other end.Envelope
The first obturator 30 in closure is arranged on that in collecting tank 28, the second obturator 32 in obturator is arranged on vehicle car 10
Downside on.
Load-carrying unit 34 itself is bearing in convection cell path by means of supporting arrangement 37 in the way of removable or movable
In the sleeve 36 of 24 gauges.Can be by the first obturator 30 in this two obturators in the First terminal point position of mobile route
In entrance side sealing fluid path 24.On the corresponding end of sleeve 36 for this reason, the intrinsic pressure pi of the first obturator presses.This
Situation is shown in the drawings.
At the second opposite final position of mobile route, can be by the second obturator 32 in this two obturators
In outlet side sealing fluid path 24.In this condition, the second obturator 32 is pressed by ambient pressure pu with its potted component 38
To on corresponding the other end of sleeve 36.
Valve 26 is thus for the pressure on the first end according to drainage equipment 16 or compartment inner space 14
Pressure reduction between pressure p u of on the second end of pi and drainage equipment 16 or compartment surrounding 20 airtightly closes stream
The valve in body path 24.When one of this two pressure p i, pu be sufficiently above corresponding another when (pi<Pu or pi>Pu), this valve
26 always sealing fluid paths 24.
In each of centre position between this two final positions of mobile route, fluid path 24 or many or
Open less.
First obturator 30 now forms the float part 40 of operation device 42 simultaneously, and described operation device is used for according to receipts
The height of collection (unshowned) water column of water in collecting tank 28 opens valve 26.
There is following function：
Generally, compared with compartment or vehicle surrounding 20, in the inner space in the compartment of airtight vehicle
There is higher pressure p i (pi in 14>pu).The valve 26 (as shown in the drawings) of drainage equipment is in mobile route
First terminal point position in closed by means of the first obturator 30.
If causing the compression shock of ambient pressure pu so that be temporarily suitable for is pu>>Pi, then pressure p u will be closed
Body device be raised to mobile route the second final position so that valve 26 within the time being significantly less than one second by means of the second envelope
Closure 32 sealing fluid path 24.
This two obturators 30,32 plate-likes ground constitute so that in pressure p i and surrounding 20 in inner space 14
The corresponding face that pressure p u can act on thereon can simply be matched with valve 26 other parameters (closure means 30,32,
34th, 38 weight, coefficient of friction of supporting arrangement 37 etc.).
The water internally occurring in space 14 enters in the floor area 12 in compartment and is collected in this place receiving
Constitute, in collection groove 28, the water column increasing.The first obturator 30 being arranged in collecting tank 28 forms the float of operation device 42 simultaneously
Element 40, described operation device is used for opening valve 26 according to the height of water column.Due to buoyancy in water for the float part 40, entirely
Closure means this two from the First terminal point position mobile (raising) of mobile route to mobile route when water column is sufficiently high
So that discharging the fluid path 24 for being collected in the water in collecting tank 28 in centre position between final position.Water is extremely
A few part is then able to leave collecting tank 28 through fluid path 24 and exit region 22 and exports to the week below compartment
In collarette border 20.Height with water column reduces, and closure means are mobile simultaneously again towards the First terminal point position of mobile route
And the first obturator 30 sealing fluid path 24 again.
Different from the example being shown in which, float part 40 need not be formed by one of obturator 30.Float part 40
Obviously also can be independent element, described independent element is coupled on obturator 30 or in closure means.
Vehicle car obviously also can be the compartment of the vehicle of trackless.The example of this vehicle is car, truck or public affairs
Automobile altogether.
