Izici zokugeleza kokulawulaivalvuikakhulukazi izinhlobo ezine zezici zokugeleza njengokuvuleka okusheshayo kwephesenti eliqondile kanye ne-parabola. Uma ifakiwe enkambisweni yokulawula yangempela, ingcindezi ehlukile yeivalvukuzoshintsha ngokushintsha kokugeleza, okungukuthi, ukulahleka kwengcindezi yengxenye yamapayipi kuzoba kuncane uma ukugeleza kuncane, ingcindezi ehlukile yeivalvukuzoba kukhulu, kanye nokucindezela okuhlukile kweivalvukuzoba kuncane uma ukugeleza kukhulu Lokhu kuhlukile ezicini ezingokwemvelo zeivalvuisici esibizwa ngokuthi ukugeleza okuphumelelayo isici sokuqala okusheshayo isici se-valve yangaphakathi simise okwediski, ikakhulukazi esisetshenziselwa isenzo sokuvula nokuvala.
Ukulawula ukuma kobuso be-valve spool
Izici zokulawula ukugeleza kwe-ivalvukunqunywa ukuhlanganiswa kwezici zokugeleza kwe-ivalvukanye nephampu yokucubungula amapayipi, njll. NgokwesilinganisoivalvuUkulahlekelwa yingcindezi entweni ngayinye yokulawula kanye nohlelo, isilinganiso sokulahlekelwa yingcindezi yevalvu ohlelweni lwezinto zokulawula sikhethiwe kuthebula elilandelayo Izici zokugeleza kwevalvu Ukulawulwa kokugeleza noma ukulawula izinga loketshezi ngaphansi kuka-40% Ukulawulwa kokugeleza noma ukulawula izinga loketshezi ngaphezu kuka-40% Ukulawulwa kwengcindezi noma ukulawula izinga lokushisa ngaphansi kuka-50% Ukulawulwa kwengcindezi noma ukulawula izinga lokushisa ngaphezu kuka-50% Umugqa oqondile ngoba ukulahleka kwengcindezi yepayipi kuhambelana nesikwele sezinga lokugeleza kuyanda, uma izici zomzimba wevalvu ziyizinguquko ezilula eziqondile, ukucindezela okuhlukile kwevalvu kuyanda lapho ukugeleza kuncane, ukugeleza kwevalvu kuzoba kukhulu kakhulu, umehluko wengcindezi yevalvu uyancipha lapho ukugeleza kukhulu, futhi ukugeleza akunakulingana nokuvulwa kwevalvu. Kulokhu, ukwengeza izici zepayipi kanye nephampu ukuze kufezwe ukulawula ukugeleza okuzimele ngobukhulu bokugeleza futhi okulingana nokuvulwa kwevalvu kuphela inhloso yokuklama izici ezilinganayo zamaphesenti.
Uhlelo lwamapayipi kanye nokulahlekelwa yingcindezi
Isenzo se-valve yokulawula singakhethwa ngokuya ngokuhlanganiswa kwedivayisi yokushayela kanye nomzimba we-valve.
Inhlanganisela yomzimba we-drive ne-valve kanye nokusebenza kwe-valve (isibonelo se-valve yesihlalo esisodwa)
Isenzo se-valve sihlanganisa isenzo esihle isenzo esibuyela emuva uhlobo lokubamba izindlela ezi-3 uhlobo lwe-diaphragm kanye nohlobo lwesilinda i-pneumatic drive isenzo esihle singokwandisa isignali yokucindezela UKUVALA indlela ye-valve, eyaziwa nangokuthi UMOYA WOKWENZA Isenzo esibuyela emuva singokwandisa isignali yokucindezela UKUVULA indlela ye-valve, eyaziwa nangokuthi UMOYA wokuvula noma Isignali yokusebenza kagesi ingaguqulwa ibe isignali yomoya ngokusebenzisa indawo. Uma isignali yokusebenza imisiwe noma umthombo womoya uphazamisekile futhi ugesi unqanyuliwe, sicela ukhethe i-valve YOKUVALA noma ukuvula ucabangela ukufaneleka kokuphepha kwenqubo.
Isibonelo, lapho kulawulwa inani le-asidi ngokusebenzisaivalvuenkambisweni yokuxuba amanzi ne-asidi, kuphephile futhi kunengqondo ukuvala ukulawula i-asidiivalvuuma umugqa wesignali kagesi uphukile noma amapayipi esignali yomoya evuza futhi umthombo womoya uphazamisekile futhi ugesi unqanyuliwe. I-valve yesenzo esibuyela emuva kufanele isetshenziswe.
