The specific embodiment
Further specify the utility model below in conjunction with accompanying drawing and embodiment.
Embodiment: the utility model comprises valve body 1, cooling mechanism 2, blowdown apparatus 3, breather check valve 4 and outgassing nonreturn valve 5.
Said valve body 1 is provided with free air diffuser outlet 11, outlet passageway import 12, free air diffuser 13, outlet passageway 14, goes up gas passage 15, the second connection air flue 18 that is communicated with free air diffuser 13 and following gas passage 16 respectively of the first connection air flue 17, the two ends that are communicated with free air diffuser 13 and last gas passage 15 respectively of gas passage 16, two ends, the third connecting air flue 19 that two ends are communicated with outlet passageway 14 and last gas passage 15 respectively down; Comprise that also the upper spring 1a and upper piston 1b, the end that are positioned at gas passage 15 pass the second connection air flue 18 and be positioned at the lower piston 1d of gas passage 16 down with lower spring 1c; And the bottom 1e that is provided with pore 1e1, the other end of said lower piston 1d is positioned at first and is communicated with air flue 17.
Said cooling mechanism 2 comprise admission port 21, air extractor duct 22, sewage draining exit 23, in be provided with reciprocating type gas passage 241 cooling tank 24, be positioned at the many condensation columns 25 of compound gas passage 241 and collect dirty chamber 26, be fixed on the radiating gill 27 in cooling tank 24 outsides; Said reciprocating type gas passage 241 is " bow " the shape passage; Its two ends are communicated with admission port 21 and air extractor duct 22 respectively, and the dirty chamber 26 of said collection is communicated with sewage draining exit 23.
The blowdown shell 31, the two ends that are provided with mudhole 311 and central through hole 312 bottom said blowdown apparatus 3 comprises are respectively equipped with the pull bar 32 of sewage draining valve 321 and draw ring 322, are enclosed within the holddown spring 33 on the pull bar 32; One end of said pull bar 32 passes central through hole 312 and is connected with draw ring 322, and the two ends of said holddown spring 33 are connected with the lower surface of sewage draining valve 321 and the bottom side inside face of blowdown shell 31 respectively.
Said free air diffuser outlet 11 is communicated with admission port 21 and air extractor duct 22 respectively with outlet passageway import 12; Said breather check valve 4 is positioned at free air diffuser outlet 11 and (sees shown in Figure 4; Also can free air diffuser export 11 and admission port 21 between or in the admission port 21); Outgassing nonreturn valve 5 is positioned at outlet passageway 14 (seeing Fig. 3, shown in Figure 4), and said sewage draining valve 321 is positioned at the below of sewage draining exit 23, captives joint with cooling tank 24 through bolt in the upper end of said blowdown shell 31.
The working process of the utility model is following:
(1) high temperature and high pressure gas from air compressor gets into free air diffuser 13; And get in the reciprocating type gas passage 241 of cooling tank 24 through free air diffuser outlet 11, breather check valve 4 and admission port 21 successively; Because the thermolysis of cooling tank 24 itself, many condensation columns 25 and radiating gill 27; The temperature of high temperature and high pressure gas can descend fast, and promptly high temperature and high pressure gas is by cooling rapidly, simultaneously; Gas also can produce a plurality of eddy current, and the foreign material such as moisture greasy dirt in the gas are compiled, collect in the dirty chamber 26 heavy gathering.
(2) cooled high pressure gas get in the outlet passageway 14 through air extractor duct 22 and outlet passageway import 12, and further through outgassing nonreturn valve 5 high pressure gas are supplied with the car load brake system.When air pressure constantly was increased to the atmospheric pressure value of designing requirement, high pressure gas got into through third connecting air flue 19 and go up gas passage 15, and overcome the pressure of upper spring 1a; With the upper piston 1b jack-up that makes progress, at this moment, first be communicated with air flue 17 the upper end be opened; High pressure gas get into first and are communicated with in the air flue 17; Lower piston 1d is under the effect of high pressure gas, and the elastic force that overcomes lower spring 1c moves down, and the lower end of the second connection air flue 18 is opened; High temperature and high pressure gas in the free air diffuser 13 directly gets into gas passage 16 down, and through in the pore 1e1 exhaust to atmosphere on the bottom 1e.In this process, the atmospheric pressure value of the gas in the reciprocating type gas passage 241 is the designing requirement force value, is high pressure gas.
(3) spur draw ring 322 downwards; Sewage draining valve 321 moves down through the pressure that pull bar 32 overcomes holddown spring 33; Sewage draining exit 23 is opened, and compiles, from mudhole 311, sprays under the heavy effect that gathers the high pressure gas of foreign material in reciprocating type gas passage 241 such as moisture in the dirty chamber 26 of collection, greasy dirt.
(4) when the high pressure gas in the outlet passageway 14 cause atmospheric pressure value to be lower than the designing requirement force value because of being used; The air pressure of the high pressure gas in the last gas passage 15 also descends simultaneously, and upper piston 1b moves down under the effect of upper spring 1a, and the upper end of the first connection air flue 17 is closed; At this moment; Do not had high pressure gas in the first connection air flue 17, lower piston 1d moves up under the effect of lower spring 1c, and the lower end of the second connection air flue 18 is closed.High pressure gas in the free air diffuser 13 get into outlet passageway 14 through free air diffuser outlet 11, breather check valve 4, admission port 21, reciprocating type gas passage 241, air extractor duct 22 and outlet passageway import 12 successively, and through outgassing nonreturn valve 5 outside air feed.
