Embodiment
Below in conjunction with the accompanying drawings, the present invention is described in detail.
In order to make the purpose , technical scheme and advantage of the present invention be clearer, it is right below in conjunction with drawings and Examples
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
As shown in figure 1, a kind of plunger type triple valve, including valve body constitute and are arranged on the piston group in valve body composition
Into, the valve body composition includes valve body 11a and is fastened on the bonnet, 11b and bottom flange 11c of valve body 11a upper and lower sides,
The piston composition includes main piston 1, main piston rod 2 and stabiliser bar 3, and the upper end of main piston rod 2 passes through locking nut 12
It is connected with main piston 1, the lower end of main piston rod 2 is threaded togather with stabiliser bar 3, the main piston 1 and valve body
It is provided with O shapes rubber seal 13 between 11a inwalls, knot is sealed using rubber diaphragm more than the main piston portion of existing all kinds of distributing valves
Structure, though good seal, is limited by diaphragm plate structure material itself, repeatedly occurs diaphragm plate perforated phenomenon after action, causes whole
Defective valve, and rubber diaphragm short life are acted on, must be changed within 2 years, is to influence the one of the main reasons of distributing valve time between overhauls(TBO),
And the main piston part of the triple valve uses O shape rubber seal coil structures, sealing property is reliable, and service life is long, can effectively prolong
The time between overhauls(TBO) of long locomotive distributing valve.
Wherein, slip cap 4 is cased with the periphery of main piston rod 2, master control set 5 is cased with the periphery of slip cap 4, it is described
Master control set 5 is pressed on valve body composition, be radially provided with the slip cap 4 slip cap alleviate position inflation through hole 4a,
Slip cap retarder location inflates through hole 4b and slip cap exhaust annular groove 4c, and master control is radially provided with master control set 5
Set alleviation position inflation through hole 5a, master control set retarder location inflation through hole 5b and master control set exhaust hole 5c, delay in the slip cap
Solve position inflation through hole 4a, slip cap retarder location inflation through hole 4b, slip cap exhaust annular groove 4c, master control set and alleviate position inflation through hole
5a, master control set retarder location inflation through hole 5b and master control set exhaust hole 5c upper and lower are correspondingly arranged on sealing ring respectively,
The path connected with train pipe, work reservoir, application reservoir and exhaust outlet is respectively arranged with the valve body composition, wherein with
The gas circuit of train pipe connection is divided into gas circuit A6 and gas circuit B7 two-way.The triple valve and the train pipe in Pneumatic brake systems, work
Reservoir is connected with application reservoir, when train tube pressure changes, triple valve according to train pipe with work reservoir pressure differential come
The pressure change of control action reservoir, then brake-cylinder pressure change is controlled, directly or indirectly, realize braking, delaying for locomotive or vehicle
Solution and pressurize.
As shown in Fig. 2 when position is alleviated in inflation, the gas circuit A6 and the chamber of the top of main piston 1, the gas circuit B7
Position is alleviated by master control set and inflates through hole 5a and slip cap alleviation position inflation through hole 4a, then is led to via the center of main piston rod 2
Gas circuit C8s of the central through hole B3a of hole A2a and stabiliser bar 3 respectively with the lower chamber of main piston 1 and the reservoir that works is connected, described
The gas circuit D9 of application reservoir is vented annular groove 4c by slip cap and connected with exhaust outlet 10.
When triple valve, which is in, just fills wind state, work reservoir, application reservoir pressure are zero, train tube pressure air warp
Mounting surface hole enters above main piston, and main piston is pushed down on, and main piston rod promotes slip cap to move downwardly together by shoulder thereon,
Untill when main piston bottom surface encounters valve body, now triple valve is in inflation alleviation position.
As shown in figure 3, in service application position, the gas circuit A6 and the chamber of the top of main piston 1, the work wind
The gas circuit C8 of cylinder is by the central through hole B3a of stabiliser bar 3, then inflates through hole 4b via slip cap retarder location and master control set is braked
Position inflation through hole 5b is connected with the gas circuit D9 of application reservoir.
When train pipe more than service braking speed to depressurize, because work reservoir pressure air is higher than train tube pressure, in
It is that certain pressure differential is generated in main piston both sides, therefore primary piston overcomes the friction with master control inner room into drive slip cap
Resistance is moved up, and reaches retarder location, is formd work reservoir to application reservoir gas fill port, is produced braking action.
As shown in figure 4, at service lap position, the path and work reservoir and application reservoir of train pipe and work reservoir
Path disconnect, work reservoir and application reservoir pressure keep.
Train pipe stops decompression, and initial stage, work reservoir was still to effect because main piston and slip cap are all also in retarder location
Reservoir fills wind, thus work reservoir pressure continues reduction, until the train pipe and work reservoir pressure of main piston both sides are close
When, under main piston Gravitative Loads, make primary piston into moving down, the path of cut-out work reservoir and application reservoir works
Reservoir stops filling wind to application reservoir, and work reservoir and application reservoir pressure are kept, and triple valve now is in service lap position.
The present invention is after fully investigation locomotive brake gear user use requirement and operating habit, and the triple valve eliminates existing
The office of locomotive distributing valve subtracts and the urgent additional functionality such as supercharging, only retains brake riggings, alleviation and pressure maintaining effect function, reduces
Point occurs for the failure of triple valve, and simple in construction, reliable effect, type approval test result shows that the triple valve fatigue endurance test can
Up to more than 3 × 105 times.
The various rail vehicle Pneumatic brake systems such as locomotive, car are present invention can be suitably applied to, EMUs can also be used as
Alternate brake machine, can not only meet the air damper requirement of indirectly-acting mode, can be used for the direct mode of action
Air damper, can replace a variety of distributing valves in existing track traffic Pneumatic brake systems, with extensive promotion prospect.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
Any modifications, equivalent substitutions and improvements made within refreshing and principle etc., should be included in the scope of the protection.
