Intshayelelo yemveliso
Ivalve yombane yokulinganisa kukuqonda ulawulo lokuthontsiza lokuhamba ngolawulo lombane.Isixhobo sokulawula uxinzelelo lombane siqukethe i-air inlet kunye ne-exhaust elawula i-valve ye-solenoid yokutshintsha, i-sensor yokufumanisa uxinzelelo kunye nesiphaluka sokulawula.Xa kukho umqondiso wegalelo, ivalve yokungena ye-solenoid iyavulwa, ivalve ye-solenoid ephumayo ivaliwe, ivalve ephambili inika umoya kwigumbi lomqhubi wenqwelomoya, kwaye undoqo wevalve engundoqo wehla ukuya kwisiphumo soxinzelelo lwesibini.
Ukuhlelwa kwemigaqo yolwakhiwo
Xa isignali yegalelo inyuswa, i-valve ye-pilot ye-1 ye-valve ye-solenoid yokunikezelwa komoya iguqulwa, kwaye i-valve ye-solenoid yokukhupha umoya ikwimeko yokusetha ngokutsha, emva koko uxinzelelo lomoya lungena kwigumbi lomqhubi we-5 ukusuka kwi-port ye-SUP. ivalve ye-1, kunye noxinzelelo kwigumbi lomqhubi wenqwelomoya, kwaye uxinzelelo lomoya lusebenza kwindawo ephezulu ye-diaphragm 2, ukuze i-valve core ye-4 edityaniswe ne-diaphragm 2 ivulwe kwaye i-valve yokukhupha i-3 ivaliwe. , okubangela uxinzelelo lwemveliso.Olu xinzelelo lwemveliso lubuyiselwa kwisekethe yokulawula i-8 ngokusebenzisa i-sensor yoxinzelelo 6. Apha, uxinzelelo lwemveliso lufaniswa ngokukhawuleza nexabiso elijoliswe kuyo lide lilingane nomqondiso wegalelo, ukwenzela ukuba uxinzelelo lwemveliso lutshintshe ngokulingana nomqondiso wegalelo. .Ngenxa yokuba kungekho sixhobo sokuvala umbhobho, isivalo asivali kukungcola kwaye sinokuthembeka okuphezulu.
