Above-mentioned all places of being slidingly sealed are provided with sealing ring.
In an initial condition, pressure gas source inwardly supplements compressed gas by inflation inlet 4, and compressed gas pushes down on unidirectionally
Valve 22, tower spring 23 are compressed, and pressed gas is entered in opening and closing chamber E by the gap between check valve 22 and valve body 1, then logical
Cross gas source interface 18 to enter in air accumulator, complete gas storage work, prepared to provide brake pressure gas.
Brake modes control pressure gas is waited to enter in main control air inlet 6 by foot-operated, a part of compressed gas enters
Into main control chamber C, main piston 9 is promoted to move down, a part of compressed gas is entered in the first pressurization control chamber A, works as pressure
After power overcomes the elastic force of elastic component 13, the first charged piston 7 is promoted to move down, the first charged piston 7 passes through the first fore-set
7a pushes down on the second charged piston 8, and a part of pressed gas is entered in the second pressurization control chamber B, also promotes the second supercharging
Piston 8 moves down, and booster action is promoted by the supercharging of the first charged piston 7, the second charged piston, compared to no first
When charged piston 7, the second charged piston 8, the pressure requirement to the pressure air of input can be reduced, that is, reaches the work of energy-conservation
With then, main piston 9 pushes down on valve element 20, is formed between valve element 20 and valve body 1 and is available for what compressed gas in air accumulator came out
Gap, the compressed gas in air accumulator enter by gas source interface 18, opening and closing chamber E, brake chamber D and braking delivery outlet 5 successively
Into brake piping, and then brake is completed, afterwards in the presence of each spring element, all parts are playbacked, and work as storage
When gas pressure intensity deficiency in gas tank, work is inflated again.
During above-mentioned use, when elastic component 13 is in free state, it is empty that charged piston 7 is located at its activity
Between bottommost, the pressurized effect of the first charged piston 7 can be adjusted by booster body, when adjusting rod 14 moves up simultaneously
When fixed, i.e. from becoming big with a distance from main piston 9, elastic component 13 is compressed the first fore-set 7a of the lower section of charged piston 7, for supercharging
Piston 7 provides a upward elastic force, when main control air inlet 5 is in the case where being passed through the compressed gas of same pressure, first
Charged piston 7 just becomes big to move down the pressure needed for the elastic force of the required elastic component 13 overcome, that is, is used for overcoming bullet
The pressure of power becomes big, for promoting the pressure of the first charged piston 7 just smaller, so in such cases, main piston 9 moves down
Controling power it is just smaller, the gap for being available for compressed gas in air accumulator to come out formed between valve element 20 and valve body 1 is just smaller, institute
With just smaller to the pressure in brake piping provided in air accumulator, braking effect is weaker；Conversely, when adjusting rod 14 moves down
And when fixation, to the pressure in brake piping with regard to larger provided in air accumulator, braking effect is stronger, and said process
In be adjusted to electrodeless regulation, can arbitrarily be adjusted according to actual conditions, very convenient, practical, i.e., charged piston 7 is located at it
The bottommost of activity space, i.e., the effect being now pressurized is maximum, remote when being moved upwards up to the first charged piston 7 by adjusting rod 14
During from first partition 2, elastic component 13 is compressed, and provides a upward elastic force for charged piston 7, the effect being now pressurized is 0.
On the other hand, it can realize whether pressed gas actively adds to the second charged piston 8 by the opening and closing of valve
Pressure, coordinates above-mentioned electrodeless regulation so that whole device uses very flexible.
So can by controlling adjusting rod 14 not produce pressurized effect come the first pressurization control chamber A, certain first
Valve can also be provided with pressurization control chamber A, the first pressurization control chamber A, the second pressurization control are controlled by valve respectively
Chamber B's is turned on or off, and realizes the purpose of any adjustment.
Due to cross-sectional area (the i.e. upper and lower surfaces of main piston 9 of the main control chamber C cross-sectional area more than brake chamber D
Area), so in the poised state of supply, due to F=PS, so in the atmospheric pressure value of compressed air caused by brake chamber D
More than main control chamber C atmospheric pressure value, i.e. the atmospheric pressure value of brake chamber D is the certain multiple of main control chamber C atmospheric pressure values, based on the multiple
The ratio of control chamber C cross-sectional area divided by brake chamber D cross-sectional area, the present invention are according to the situation of road conditions and vehicle
Make the function of without using the first pressurization control chamber A and the second pressurization control chamber B, equally also having more preceding braking.
In addition, the bottom of valve body 1 is provided with emergency braking mechanism, the present invention improves for the structure in prior art, therefore
Emergency braking mechanism is same as the prior art, is described briefly herein, and emergency braking mechanism is slidably arranged in valve body 1 including sealing
On the travelling carriage 28 with upper and lower opening, the inner side of travelling carriage 28 enclosed to form above-mentioned opening and closing chamber E, and valve element support 19 is fixed
The inner chamber bottom of travelling carriage 28 is arranged on, is provided with the side wall of travelling carriage 28 and is connected respectively with one-way valve structures, gas source interface
Logical hole, the baffle plate 29 with holes for limit slippage frame 28 to bottom offset is fixedly installed on valve body 1, in a braking operation
In flow, after end, after all parts playback, main piston 9 moves up, and it forms gap, valve element between valve element 20
Via 20a is provided with 20, the pressed gas remained on brake piping is flowed back in brake chamber D, then along main piston 9 and valve
Gap between core 20 is flowed in via 20a, is then discharged into through the hole on baffle plate 29 in air, and said process is normally to unload gas
Process.
Brake hard principle is：Under general state, due to having compressed air on inflation inlet 4, the pressure top opening one-way
, can be by promoting the hierarchic structure of travelling carriage 28 so that travelling carriage 28 moves down, and is resisted against baffle plate 29 while valve 22
On, i.e., the pressure in pressure and air accumulator at inflation inlet 4 is in poised state, when brake hard, at inflation inlet 4
Compressed air disappears, and pressure herein is 0, and this, which results in the pressure that driving travelling carriage 28 moves up and is more than, drives it to moving down
Dynamic pressure, so travelling carriage 28 moves up, and drives valve element 20 to move up by holding out against spring 21, mobile process
In, valve element 20 contacts with main piston 9 first, forms sealing and coordinates, and then travelling carriage 28 continues to stop after moving up one end distance, institute
Coordinated with valve element 20 and main piston 9, enclose the connection with air, gap, air accumulator are formed between valve element 20 and travelling carriage 28
In pressed gas entered by the gap in brake chamber D, then into brake piping, realization is died brake hard
Journey.
Embodiments of the invention provide for the sake of example and description, and are not exhaustively or by this to send out
It is bright to be limited to disclosed form.Many modifications and variations are obvious for the ordinary skill in the art.Choosing
Select and describe embodiment and be to more preferably illustrate the principle and practical application of the present invention, and make one of ordinary skill in the art
It will be appreciated that the present invention is so as to designing the various embodiments with various modifications suitable for special-purpose.
