DIN EN 15611:2011-02 EN 15611:2008+A1:2010 (E) 5 1 Scope This European Standard is applicable to relay valves designed to control the brake cylinder pressure of compressed air brakes fitted to railway vehicles, in association with an air brake distributor valve or other control device, and in
26、 response to a change in vehicle load that is either continuously variable or in two stages i.e. empty - loaded. Relay valves operating with other pressures, in particular the brake pipe pressure, are not included. This European Standard specifies the requirements for the design, manufacture and tes

32、ariation of one or more input pressures NOTE 1 See Figure 1. DIN EN 15611:2011-02 EN 15611:2008+A1:2010 (E) 6 Key 1 first input pressure 2 second input pressure 3 control signal - continuous load sensing pressure (Lcp), or control signal - empty/load signal pressure (Lsp), or mechanical input (lever
33、) or electrical input 4 auxiliary reservoir pressure, supply pressure (AR) 5 output pressure 6 relay valve Figure 1 Relay valve, pressures and control signals NOTE 2 The definition of “relay valve” in EN 14478 is specific to a load dependant relay valve. This EN standard considers one or more input
34、pressures in accordance with the diagram in Figure 1. 3.1.2 input pressure control pressure received by the relay valve NOTE Pressure generally considered as being the output pressure from a distributor or a brake control unit; sometimes referred to as pilot pressure or dummy brake cylinder pressure
35、. 3.1.3 output pressure pressure output from the relay valve NOTE Pressure generally considered as being the brake cylinder pressure when the relay valve is used in a variable load braking system. This pressure can also be used as the input pressure to another relay valve. The output pressure can ob
36、tain one, two or three fixed levels or it can be changed continuously between a minimum and a maximum or vice versa. 3.1.4 relay valve ratio ratio of the output pressure to input pressure DIN EN 15611:2011-02 EN 15611:2008+A1:2010 (E) 7 3.1.5 control signal signal received from the continuous load s
37、ensing device (Lcp) or empty - loaded changeover device (Lsp) or a mechanical input (lever) or an electrical input that varies the relay valve ratio dependant on vehicle load NOTE This can also be a speed signal or other parameter, dependant on the relay valve application. 3.1.6 Relay valve types 3.
38、1.6.1 single stage relay valve relay valve type A relay valve with one fixed relay valve ratio, where the ratio can be less (step-down), equal or greater (step-up) than 1 3.1.6.2 multi stage relay valve relay valve type B relay valve with more than one fixed relay valve ratio, where the ratios can b
39、e less (step-down), equal or greater (step-up) than 1 3.1.6.2.1 relay valve type B1 multi stage relay valve that can change relay valve ratio during a brake application NOTE Typically used on vehicles normally operated in empty or fully loaded condition. 3.1.6.2.2 relay valve type B2 multi stage rel
40、ay valve where a change of relay valve ratio cannot take place during a brake application NOTE Blocking the relay valve ratio during brake application is typically used to avoid frequent changeovers taking place on vehicles operated near the changeover weight. 3.1.6.2.3 empty/load relay valve specif
41、ic type of multi stage relay valve (type B1 or B2) with only two stages, giving an empty (tare) or a loaded output pressure proportional to input pressure dependant on the load signal input 3.1.6.3 variable load relay valve relay valve type C relay valve with a continuously changeable relay valve ra
42、tio, where a load signal is used to change the ratio 3.1.6.4 multi stage variable load relay valve relay valve type C1 relay valve with a continuously changeable relay valve ratio, where a load signal is used to change the ratio and with a multi stage feature added NOTE Typically a load signal is us
43、ed to change the relay valve ratio and a control signal (automatic or manual) is used to change the stage(s). The typical result is that at the same load and input pressure, in the lower stage (e.g. P-mode, passenger train) results a lower output pressure and in a higher stage (e.g. R-mode, rapid pa
44、ssenger train) this results in a higher output pressure. 3.1.6.5 two (multi) input relay valve relay valve type D relay valve (type A, B or C) with two (or more) input pressures, controlling a single output pressure DIN EN 15611:2011-02 EN 15611:2008+A1:2010 (E) 8 3.1.6.6 variable load relay valve w

47、nsitivity change of input pressure, starting at 0 bar which causes the output pressure to start increasing NOTE See Figure 2. 3.1.9 sensitivity at reversal change of input pressure causing a variation of output pressure, when the change of input pressure is changing its direction from increasing to
