Ubunjalo bokugeleza kokulawulaivalvuikakhulukazi ziinhlobo ezine zeempawu zokugeleza ezifana namaphesenteji we-linear ukuvulwa okurhabako kanye ne-parabola. Lokha nayifakwa enqubweni yokulawula yangempela, umfutho ohlukileko weivalvukuzokutjhuguluka ngokutjhuguluka kokugeleza, okutjho bona, ukulahlekelwa mfutho wengcenye yamapayipi kuzokuba kuncani lokha ukugeleza kuncani, umfutho ohlukileko weivalvukuzokuba kukhulu, begodu umfutho ohlukileko weivalvukuzokuba mncani lokha ukugeleza kukhulu Lokhu kuhlukile ebuntwini obukhona be-ivalvuubujamo obubizwa ngokuthi ubujamo bokugeleza okusebenzako bokuthoma okurhabako ubujamo bevalvu yangaphakathi bufana nediski, isetjenziselwa khulu ukuvula nokuvala isenzo.
Ukulawula ubujamo bephasi le-valve spool
Iimpawu zokulawula ukugeleza kweivalvuzibekwa ngokuhlanganiswa kweemfanelo zokugeleza kwe-ivalvukanye nepompo yokuphayipha, njll. Ngokuya ngesilinganiso seivalvuukulahlekelwa mfutho entweni ngayinye yokulawula nehlelo, isilinganiso sokulahlekelwa mfutho wevalvu ehlelweni lento yokulawula sikhethwe etafuleni elilandelako Iimfanelo zokugeleza kwevalvu Ukulawula ukugeleza nofana ukulawulwa kwezinga lamanzi ngaphasi kwama-40% Ukulawula ukugeleza nofana ukulawulwa kwezinga lamanzi ngaphasi kwama-40% ukulawulwa kwegandeleleko nofana ukulawulwa kwezinga lokutjhisa ngaphasi kwama-50% wokulawula umtjhini nofana ukulawulwa kwamazinga womtjhiso ngaphezu kwama-50% ngombana ukulahlekelwa komfutho wepayipi kulinganiselwa isikwere sezinga lokugeleza liyakhula, nangabe ubujamo bomzimba wevalvu butjhuguluka okulula, umfutho ohlukileko wevalvu uyakhuphuka lokha ukugeleza kuncani, ukugeleza kwevalvu kuzokuba kukhulu khulu, umehluko womtjhini wevalvu uyancipha lokha ukugeleza kukhulu, begodu ukugeleza angeze kwalingana nokuvulwa kwevalvu. Ukuze lokhu, ukungezelela ubujamo bephayiphu nepompo ukufikelela ubukhulu bokugeleza okuzijameleko begodu ngokulingana nokuvulwa kwevalvu kwaphela umnqopho womklamo weempawu zamaphesente alinganako.
Irherho lokuphayipha nokulahlekelwa mfutho
Isenzo sokulawula ivalvu singakhethwa ngokuya ngokuhlanganiswa kwedivayisi yokutjhayela nomzimba wevalvu.
Inhlanganisela yomzimba wedrayivu nevalvu nesenzo sevalvu (isibonelo sevalvu yesihlalo esisodwa)
Isenzo sevalvu sifaka hlangana isenzo esihle isenzo sokubuyela emuva isenzo sokubamba umhlobo weendlela ezi-3 umhlobo wedayaphragmu nomhlobo wesilinda umtjhayeli we-pneumatic isenzo esihle kungenxa yokukhuphula isignali yomfutho UKUVALA indlela yevalvu, eyaziwa nangokuthi yi-AIR TO CLOSE isenzo sokubuyela emuva kungenxa yokukhuphula isignali yomfutho ukuVULA indlela yevalvu, eyaziwa nangokuthi yi-AIR ukuvula isignali yokusebenza itshwayo lomoya nge-locator. Lokha isiginali yokusebenza nayimisiweko nofana umthombo womoya uphazanyiswa begodu amandla avalelwe, sibawa ukhethe ivalvu UKUVALA nofana uvule ngokucabangela ukuphepha kwenqubo.
Ukwenza isibonelo, lokha nakulawulwa inani le-esidi nge-ivalvungesikhathi sokuhlanganisa amanzi ne-esidi, kuphephile begodu kunengqondo ukuvala isilawuli se-esidiivalvulokha umzila wesiginali kagesi nawuphukileko nofana amapayipi wesiginali yomoya navuzako begodu umthombo womoya uphazanyiswa begodu amandla acinywa. Ivalvu yokubuyela emuva kufanele isetjenziswe.
