Portion chamber g1 is connected with work reservoir, is provided with rubber seal 6, described rubber is close between described main valve housing 2 and master control set 3
Seal 6 is separately positioned on above chamber volume aerofluxuss annular groove d2, below chamber volume gasing ring groove g4 and chamber volume aerofluxuss annular groove d2
And chamber volume gasing ring groove g4 between, by moving up and down of master control set 3, when distributing valve is in inflation and alleviates position, described appearance
Long-pending room exhaust channel r1p is open and chamber volume gas fill port r1c is closed, and when distributing valve is in retarder location, described chamber volume is filled

During retarder location to inflation alleviates position switching, on described master control set 3, corresponding rubber seal 6 is first closed chamber volume and is filled
After gas path r1c, then by corresponding rubber seal 6, chamber volume exhaust channel r1p is opened.
The operation principle of the present invention is:
As illustrated in fig. 1 and 2, it is that the present invention alleviates the schematic diagram of position in inflation.
A, just inflation.
When Train line charging, pressure air waits until this distributing valve through train pipe, arm, then, has a road through path l1
Form 5 upper chamber to piston, piston composition 5 moves down, and piston composition 5 drives master control inner sleeve 7 to pass through by piston rod 4 simultaneously
On piston rod 4, shoulder promotes master control set 3 to move down together, until till main valve body is encountered in piston composition 5 lower ends.At this moment, piston set
Become 5, piston rod 4, master control inner sleeve 7, master control set 3 to be in inflation and alleviate position.Train tube pressure air is through different paths respectively
To reservoir (room) inflation such as work reservoir, auxiliary reservoir, the reservoirs such as work reservoir, auxiliary reservoir (room) are made to be charged to level pressure (as 500kpa
Or 600kpa), it is used for deceleration or stopping brake during train operation.
Work reservoir inflation: train tube pressure air → l2 → main valve housing correspondence path → master control set l8 → master control set g2 →
Lower chamber g1 → work the reservoir of piston composition.
Auxiliary reservoir is inflated: train tube pressure air → charging portion (being controlled by work reservoir) → auxiliary reservoir.
On the upside of the relaying encapsulating valve of relay, f2 and auxiliary reservoir always connect, and auxiliary reservoir pressure air is relaying encapsulating
Upside is waited, and is that next step braking action is got ready.
Train tube pressure air → l4 → main valve housing corresponds to path → master control set l5 → master control set l6, during for braking next time
Play first stage local reduction to get ready.
B, reinflated and alleviation.
Train pipe passes through decompression, after so that train is braked, when again to Train line charging, due to train pipe supercharging,
Destroy piston and form the pressure balance in service lap for 5 both sides, when the pressure difference that piston forms 5 both sides produce to
When lower active force and piston form 5 gravity sums and exceeded the frictional resistance that master control puts rubber seal and main valve inner room, live
Plug composition 5 drive master control inner sleeve, master control set move down into inflation together and alleviate position.At this moment, the reservoir (room) such as work reservoir, auxiliary reservoir
Obtain reinflated, chamber volume and brake cylinder exhaust (alleviation), brake is in relieved state.
All paths when above-mentioned " just inflating ", also all have when reinflated.
Chamber volume is alleviated: chamber volume pressure air → r1 → main valve housing r1p → master control set d2 → d1 → air.
Relay relays the pressure air → r3 → valve body internal passage → chamber volume → r1 → main valve housing r1p of piston cavity of resorption
→ master control covers d2 → d1 → air.
Because this valve is two pressure equalizing system valve, so chamber volume once drains together with the pressure air of relaying piston cavity of resorption,
Their pressure drops to zero.
Checking cylinder is alleviated: relaying piston upper chamber z3 leads to checking cylinder, and cavity of resorption r3 leads to chamber volume.Because chamber volume is alleviated, destroy
The original pressure balance in relaying piston both sides, brake-cylinder pressure makes the relaying piston move down, the upper end of relaying piston rod from
Open relaying encapsulating valve, then brake-cylinder pressure air → valve body internal passage → z1 → relaying piston rod d4 → d3 → air.System
Dynamic cylinder pressure enters air, and brake forms relieved state.Meanwhile, relaying piston upper chamber z3 pressure air pass through shrinkage cavity c2 with
And the pressure air of relaying encapsulating valve epicoele z2 is in the lump through z1 → relaying piston rod d4 → d3 → air.
As can be seen here, checking cylinder pressure is controlled by volume chamber pressure.Because volume chamber pressure is once alleviated to zero, therefore braking
Cylinder pressure is also correspondingly once alleviated to zero, and brake obtains complete incidence graph.
As shown in Figures 3 and 4, it is the schematic diagram in retarder location for the present invention.
After first stage local reduction, promote that piston composition 5 pressure at both sides difference is anxious to be increased, then piston composition 5 passes through piston
Bar 4, stabiliser bar 8, graduating 9 promote master control set to overcome the frictional resistance and main valve housing between, move up further to retarder location.Due to
Master control set 3 there occurs change with the relative position of main valve housing 2, and being staggered with ju1 hole in the ju2 hole on master control set 3, has therefore cut off row
Car pipe and office subtract the path of room, and first stage local reduction's effect terminates.Meanwhile, master control set 3 on a some holes respectively with main valve
Corresponding aperture connection on set 2, defines following path, produces braking action further.
It is dark that a, train tube pressure air → l4 → main valve housing corresponds to path → master control set l5 → master control set l3 → valve inner
Road → office subtracts restriction valve (opening) → checking cylinder.So, make each vehicle by this valve of this car by a part of train pipe pressure
The office through opening for the power air subtracts restriction valve and introduces checking cylinder, here it is the effect of second stage local reduction.
When checking cylinder pressure increases to 50～70kpa, the office of making subtracts restriction valve and closes, and this path is cut off, second stage
Local reduction's effect stops.Even if the effect stopping of second stage local reduction can ensure the little decompression amount of last vehicle of train vehicle train pipe
When also there is certain brake force.
B, chamber volume inflation: work reservoir pressure air → g1 → g3 → g4 → r1c → r1 → chamber volume.
C, checking cylinder inflation: chamber volume is connected always with relaying piston cavity of resorption, so chamber volume pressure air → valve
Internal portion secret tunnel → r3, promotes and moves on relaying piston, relaying piston rod, relaying piston rod backs down relaying encapsulating valve.
The relaying encapsulating valve → z1 → valve inner secret tunnel → checking cylinder of auxiliary reservoir pressure air → f2 → back down.Then,
Checking cylinder pressure continues to increase.Meanwhile, brake-cylinder pressure air, a road enters z2 on the upside of relaying encapsulating valve, and the contracting of another path is stifled
C2 enters relaying piston upper chamber.The effect of the stifled c2 of contracting makes the boosting of relaying piston upper chamber synchronous with checking cylinder boosting.
Because the effect of second stage local reduction is substantially occurred to the aeration of chamber volume with work reservoir simultaneously
, after that is, train tube pressure air enters checking cylinder, and then, auxiliary reservoir pressure air also begins to enter checking cylinder, so
The initial pressure 50～70kpa of checking cylinder is from pressure air of both train pipe and auxiliary reservoir, and is reaching this pressure
After strong, office subtracts restriction valve and closes, and then train pipe stops inflating to checking cylinder, and only auxiliary reservoir is inflated to checking cylinder, as
Checking cylinder continues inflation, rises to great pressure, also relevant with the train pipe pressure reduction size of driver control.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all essences in the present invention
Any modification, equivalent and improvement made within god and principle etc., should be included within the scope of the present invention.
