Ngokuphuculwa okuqhubekayo kwe-industrial automation, ukusetyenziswa kweivalve yokunqunyulwa kwepneumatic lubanzi ngakumbi nangakumbi. Kwiindawo ezininzi zoshishino, iivalve ezisikiweyo zepneumatic zidlala indima ebalulekileyo, njengepetroleum, imichiza, isinyithi, izixhobo zokwakha njalo njalo. Namhlanje, siza kujonga ngokubanzi kwisakhiwo kunye nomgaqo wokusebenza we-valve ye-pneumatic cut-off valve ukuze siqonde ngcono kwaye sisebenzise ezi zixhobo zibalulekileyo.
Okokuqala, isakhiwo esisisiseko se-valve yokusika i-pneumatic
Ivalve yokusika i-pneumatic ikakhulu yenziwe ngala malungu alandelayo: umzimba wevalvu, isigqubuthelo sevalvu, undoqo wevalvu, umqhubi, umsesane wokutywina kunye neendawo zokuqhagamshela. Umzimba wevalve kunye nesigqubuthelo sevalve zibonelela ngenkxaso yesakhiwo kwivalve yokusika yokuvala umoya; I-spool licandelo eliphambili levalve yokusika i-pneumatic, enoxanduva lokulawula ukuhamba kwe-medium; Umqhubi unoxanduva lokuguqula isignali yomthombo womoya ibe yintshukumo yomatshini, eqhuba undoqo wevalve ukuqonda iswitshi; Umsesane wokutywina uqinisekisa ukusebenza kokutywinwa kwevalve; Isidibanisi sidibanisa i-valve yokusika i-pneumatic kwisixokelelwano semibhobho.
Okwesibini, umgaqo osebenzayo we-valve ye-pneumatic cut-off
Umgaqo osebenzayo wevalve yokusika i-pneumatic unokushwankathelwa njengala manyathelo alandelayo:
1. Xa i-valve ye-pneumatic cut-off idinga ukuvalwa, inkqubo yomthombo womoya inika umqondiso womoya ocinezelweyo kumqhubi. Umoya ocinezelekileyo ungena nge-air intakes ye-drive, utyhala iipiston ze-drive ngaphandle.
2. Xa ipiston yomqhubi ihambela ngaphandle, yiphakamisele phezulu i-spool ngokusebenzisa intonga yokudibanisa. Umsantsa phakathi kwe-spool kunye nesihlalo uba mkhulu, kwaye i-medium ayikwazi ukuhamba, ukuze kufezekiswe injongo yokunqunyulwa.
3. Xa ivalve yokunqunyulwa kwe-pneumatic kufuneka ivulwe, inkqubo yomthombo womoya iyayeka ukubonelela ngegesi. Intlakohlaza yomqhubi ibuyela ngasemva kwaye icinezele i-spool phantsi ukuze i-spool ingene ngokuqinileyo esihlalweni. Ngeli xesha, i-medium inokudlula kakuhle kwi-valve yokusika i-pneumatic.
4. Ukuze kuqinisekiswe ukusebenza kokutywinwa kwevalve ye-pneumatic cut-off valve, iringi yokutywina ilungiselelwe phakathi kwe-spool kunye nesihlalo. Kwimeko yokudibanisa okuqinileyo phakathi kwe-spool kunye nesihlalo, umsesane wokutywina unokuthintela ngokufanelekileyo ukuvuza kweendaba.
Isishwankathelo, ulwakhiwo kunye nomgaqo wokusebenza wevalve yokusika i-pneumatic ilula, kodwa indima yayo kwintsimi ye-industrial automation ibalulekile. Ukuqonda isakhiwo kunye nomgaqo wokusebenza we-valve yokuvala i-pneumatic isinceda ukuba sisebenzise kangcono esi sixhobo kunye nokuphucula ukusebenza kakuhle kwemveliso kunye nokhuseleko.
