Iivalvu zokujonga zinezibonelelo ezahlukeneyo kwiinkqubo zolawulo lolwelo, kwaye oku kulandelayo sisishwankathelo sezibonelelo zazo eziphambili:
Okokuqala, thintela ukubuyela umva kwe-medium
Umsebenzi oyintloko: Eyona nzuzo ibalulekileyo yevalvu yokujonga kukukwazi ukuthintela ngokuzenzekelayo ukubuya kwemidiya. Xa i-medium isiya phambili, idiski yevalvu iyavuleka ukuvumela i-medium ukuba idlule; Xa i-medium izama ukubuyisa ukuhamba, idiski yevalvu iyavaleka ngokukhawuleza, ithintela ngempumelelo i-medium ukuba ingabuyeli emva. Lo msebenzi ubalulekile ukukhusela izixhobo kunye neenkqubo ekonakaleni.
Okwesibini, ukuthembeka okuphezulu
Iimpawu zesakhiwo: Iivalvu zokujonga zihlala zinesakhiwo esilula, nto leyo eyenza kube lula ukuzigcina kwaye zingaphazami kakhulu. Umgaqo woyilo lwazo usekelwe kumthetho wendalo wokuhamba okuphakathi, ngaphandle kwezixhobo zamandla zangaphandle, ngoko ke zinokuthembeka okuphezulu.
Okwesithathu, gcina amandla
Umgaqo wokusebenza: Ivalvu yokujonga ixhomekeke kumahluko woxinzelelo lwesixhobo ngokwayo ukuze ivuleke kwaye ivale ngaphandle kokusebenzisa amandla ongezelelweyo. Oku kunika iivalvu zokujonga ithuba lokonga amandla kwiinkqubo zolawulo lolwelo.
Okwesine, ukhuseleko oluphezulu
Ukhuseleko: Ivalvu yokukhangela inokuthi ithintele ngempumelelo iingozi ezifana nokuphuma kwe-media backflow kunye nokuqhuma kwepayipi, ukuqinisekisa ukhuseleko lwezixhobo kunye nobuntu. Indima yeevalvu zokukhangela ibaluleke kakhulu kwiinkqubo zepayipi ezine-media yoxinzelelo oluphezulu okanye ezinokutsha neziqhumayo.
Okwesihlanu, ezoqoqosho kunye nokusebenza
Ixabiso liphantsi: Iivalvu zokukhangela zinexabiso eliphantsi, ubomi benkonzo ende kwaye kulula ukuzisebenzisa. Oku kwenza ukuba ivalvu yokukhangela kwinkqubo yolawulo lolwelo ibe nethuba elibanzi lokusetyenziswa kunye nexabiso lezoqoqosho.
Okwesithandathu, ukusetyenziswa okuqinileyo
Ukusetyenziswa okubanzi: Ivalvu yokukhangela ingasetyenziswa kwiindidi ezahlukeneyo zemidiya yolwelo, njengegesi, ulwelo, njl.njl., kwaye ifanelekile kwiindidi ezahlukeneyo zemizi-mveliso kunye neendawo zoluntu. Ulwakhiwo lwayo olulula, ubungakanani bayo obuncinci kunye nobunzima obuncinci kwenza kube lula ukuyifaka nokuyigcina kwiinkqubo ezahlukeneyo zemibhobho.
Okwesixhenxe, uphuhliso olukrelekrele
Iindlela zobuchwepheshe: Ngokuhambela phambili kwesayensi netekhnoloji, iivalvu zokukhangela ziya zisiba krelekrele kancinci kancinci. Ngokudibanisa iiteknoloji ezintsha ezifana ne-Intanethi yezinto kunye ne-cloud computing, ukujonga nokulawula ivalvu yokukhangela kude kunokufezekiswa ukuphucula ukwenziwa ngokuzenzekelayo kwemveliso yemizi-mveliso.
Okwesibhozo, iingenelo zohlobo olukhethekileyo
Njenge-HH44X/H micro slow closure check valve: Le valve yokujonga ayinamsebenzi usisiseko wokuthintela ukubuya kwe-medium, kodwa ikwanazo neempawu zokuxhathisa ulwelo oluphantsi, ubomi obude benkonzo, ukusebenza kakuhle njalo njalo. Isixhobo sokuvala kancinci sinokunciphisa uxinzelelo lwe-water hammer xa ivalve ivaliwe kwaye siqinisekise ukusebenza ngokukhuselekileyo kwenethiwekhi yepayipi.
Ngamafutshane, ivalvu yokujonga ineengenelo ezininzi kwinkqubo yolawulo lolwelo, kuquka ukuthintela ukubuya kwemidiya, ukuthembeka okuphezulu, ukonga amandla, ukhuseleko oluphezulu, uqoqosho kunye nokusebenza, ukusetyenziswa okuqinileyo kunye nophuhliso olukrelekrele. Ezi nzuzo zenza ivalvu yokujonga isetyenziswe kakhulu kwiinkalo ezahlukeneyo zoshishino kunye neendawo zentlalo.
