Below in conjunction with embodiment and accompanying drawing thereof the present invention is described again.

Referring to Fig. 1; a kind of relay controller with self-regulation of pressure; comprise control circuit 17; control circuit 17 is by time relay JS; timing relay JYS and time dalay indicator light DY; auxiliary reclay JZ and draining pilot lamp DP; pushbutton switch LA and run indicator DX; earth leakage protective device DZL and power light DD form; time dalay indicator light DY one tunnel connects timing relay JYS; time relay JS; auxiliary reclay JZ and terminating switch 6; another road of time dalay indicator light DY connects timing relay JYS and auxiliary reclay JZ; draining pilot lamp DP two-way connects auxiliary reclay JZ and solenoid valve 15 respectively; run indicator DX one tunnel connects auxiliary reclay JZ; another road of run indicator DX connects auxiliary reclay JZ and pushbutton switch LA; power light DD one tunnel connects earth leakage protective device DZL and terminating switch 6; another road of power light DD connects earth leakage protective device DZL and pushbutton switch LA; timing relay JYS connects high pressure travel switch 4 again; time relay JS connects auxiliary reclay JZ and low pressure stroke switch 3 respectively again; auxiliary reclay JZ connects low pressure stroke switch 3 and high pressure travel switch 4 respectively again; high-pressure cylinder 10 and low-pressure cylinder 8 are installed between pressure piping 11 and the low pressure pipeline 12 side by side; pressure piping 11 logical high-pressure cylinders 10; low pressure pipeline 12 logical low-pressure cylinders 8; pressure piping 11 also leads to high-pressure outlet 14; solenoid valve 15 is installed in the low pressure pipeline 12; high-pressure cylinder 10 unidirectional admission; built-in high-pressure cylinder back-moving spring 9-1 and high pressure push rod 1-1; high pressure push rod 1-1 goes up high pressure stroke collision block 2-1 is installed; low-pressure cylinder 8 also is unidirectional admission; built-in low-pressure cylinder back-moving spring 9-2 and low pressure push rod 1-2; support plate 16 is installed on the low-pressure cylinder 8 from top to bottom successively; hold-down nut 7; terminating switch 6; install successively from top to bottom on the low pressure push rod 1-2 and stop pressing plate 5 and low pressure stroke collision block 2-2; low pressure stroke switch 3 is installed on the support plate 16; stop high pressure travel switch 4 is installed on the pressing plate 5, steam enters low pressure pipeline 12 and low-pressure cylinder 8 from pressure piping 11 again by iron.

Referring to Fig. 1, between pressure piping 11 and the low pressure pipeline 12 chock 13 is arranged.

Referring to Fig. 1, a vapour three usefulness pipelines begin to send vapour in the whole boiling hot industry of clothes, press the button switch LA simultaneously, and steam enters high-pressure cylinder 10 by pressure piping 11, and high pressure push rod 1-1 and high pressure stroke collision block rise rapidly, have crossed high pressure travel switch 4.Because high pressure travel switch 4 is mounted on the low pressure push rod 1-2 of low-pressure cylinder 8, at this time still be in the zero-pressure state in the low-pressure cylinder 8, its terminating switch 6 is not opened, therefore high pressure travel switch 4 non-transformers at this moment and can not working.After a while, steam enters low pressure pipeline 12 and low-pressure cylinder 8, and low pressure push rod 1-2, termination pressing plate 5 and high pressure travel switch 4, low pressure stroke collision block 2-2 rise simultaneously, owing to stop the power supply that terminating switch 6 has been opened in the rising of pressing plate 5, at this moment run indicator DX is bright.When the time comes, the power supply of low pressure stroke switch 3 has been connected in the rising of low pressure stroke collision block 2-2, auxiliary reclay JZ work at this moment, and solenoid valve 15 steam bleedings and draining, DP is bright for the draining pilot lamp.This straight-through purpose of design that discharges water is: because when just having started working, its pipeline all is a low temperature, so the steam that at first enters is all changed in condensate water, and owing to be full of cold air in the former pipeline, therefore necessary at first a large amount of dischargings just can make steam put in place rapidly.The stroke of low pressure stroke collision block 2-2 plane Design of length between 0.1MPa.When low pressure stroke collision block 2-2 continues to rise to when leaving low pressure stroke switch 3, this direct circuit is resetted by low pressure stroke switch 3 and cuts off.Running hours, pressure piping 11 are continuously to low pressure pipeline 12 superchargings, and high pressure travel switch 4 continues to rise, when touching high pressure stroke collision block 2-1, and auxiliary reclay JZ work, solenoid valve 15 water descharging type steam discharges, DP is bright for the draining pilot lamp.At this moment, low pressure push rod 2-1 descends rapidly, and the power supply of solenoid valve 15 is supplied with by time relay JS, has controlled displacement simultaneously.The effect of timing relay JYS is frequent contact that prevents high pressure travel switch 4 and high pressure stroke collision block 2-1.Like this, no matter overall air pressure is high or low, no matter having, do not using back group iron, the low pressure pipeline 12 and the pressure of pressure piping 11 are equal to, kept certain pressure reduction, guaranteed the long-term mobile of steam,, solved a long-standing difficult problem even operate the iron water outlet that also can not make the front under abnormal situation at back group iron.

Referring to Fig. 1, another effect of the straight-through design of low pressure stroke switch 3 is: when the source was cut steam in the next pass of workman, high pressure push rod 1-1, low pressure push rod 1-2 descending, when low pressure stroke collision block 2-2 contacts with low pressure stroke switch 3, had also carried out straight-through steam discharge.On general, steam discharge all is flushed in the cold water storage cistern in factory, and the life that had both guaranteed the workman has the usefulness of heat, makes not residual too many carbonated drink in the pipeline again, facilitates to the beginning steam supply of next day.At last, stop pressing plate 5 and push down terminating switch 6, all cut off the electricity supply.

Referring to Fig. 1, timing relay JYS and time relay JS adopt ST3 type relay, and auxiliary reclay JZ adopts JZ7-44 type relay, and the model of button LA is LA19-110, and the model of earth leakage protective device DZL is DZL-18.
