Njengengxenye ebalulekile yesistimu yezimboni, ukufakwa okulungile kubalulekile.I-valve efakwe kahle ayiqinisekisi nje ukuhamba kahle kwamanzi esistimu, kodwa futhi iqinisekisa ukuphepha nokuthembeka kokusebenza kwesistimu.Ezindaweni ezinkulu zezimboni, ukufakwa kwama-valve akudingi nje ukucatshangelwa kwemininingwane yezobuchwepheshe, kodwa futhi nokuhambisana nemithetho nezindinganiso zokuphepha ezifanele.Ngakho-ke, ukubaluleka kokufakwa okulungile kwama-valve akubonakali nje ekusebenzeni kahle nasekuzinzeni kokusebenza kwesistimu, kodwa nasekuphepheni kwabasebenzi kanye nemishini.Ngokufakwa okulungile, izinkinga zokuvuza zingancishiswa, ukusebenza kahle kwesistimu kungathuthukiswa, izingozi zezimboni zingagwenywa, indawo ezungezile kanye nokuphila kwabasebenzi kanye nempahla kungavikelwa, ngaleyo ndlela kunikeze isivikelo esinokwethenjelwa sokukhiqizwa kwezimboni.Ngakho-ke, ukufakwa kahle kwama-valve kubalulekile futhi kungenye yezixhumanisi ezibalulekile ekuqinisekiseni ukusebenza okuphephile kwezinhlelo zezimboni.

1.I-valve eguquliwe.

Imiphumela: i-valve ehlanekezelwe, i-throttle valve, i-valve yokunciphisa ingcindezi, i-valve yokuhlola namanye ama-valve aqondisa, uma ehlanekezelwe, i-throttle izothinta umphumela wokusetshenziswa nokuphila;Amavalvu okwehlisa ingcindezi awasebenzi sanhlobo, futhi amavalufu okuhlola angaba yingozi.

Izinyathelo: Ama-valve avamile, anezimpawu zendlela emzimbeni wamavalvu;Uma kungenjalo, kufanele ikhonjwe ngendlela efanele ngokuvumelana nesimiso sokusebenza se-valve.I-valve ye-valve ye-globe valve i-asymmetrical, futhi uketshezi kufanele luvunyelwe ukuba ludlule embobeni ye-valve ukusuka phansi kuye phezulu, ukuze ukumelana noketshezi kube kuncane (kunqunywa yisimo), ukuvuleka kungukusindisa abasebenzi (ngenxa ukucindezela okuphakathi kuya phezulu), futhi okuphakathi akucindezeli ukupakisha ngemva kokuvala, okulula ukukulungisa.Yingakho i-valve yokumisa ingakwazi ukuhlehliswa.Ungaguquli i-valve yesango (okungukuthi, isondo lesandla liye phansi), ngaphandle kwalokho okuphakathi kuzohlala isikhathi eside endaweni yekhava yevalvu, kulula ukugqwala isiqu se-valve, futhi akuvumelekile kwezinye izidingo zenqubo.Akulula kakhulu ukushintsha ukupakisha ngesikhathi esifanayo.Vula i-stem gate valvu, ungafaki emhlabathini, ngaphandle kwalokho ngenxa yomswakama nokugqwala kwesiqu se-valve esiveziwe.Phakamisa i-valve yokuhlola, ukufakwa ukuze uqinisekise ukuthi i-valve disc ime mpo, ukuze i-lift iguquguquke.Swing isheke valve, ukufakwa ukuqinisekisa ukuthi izinga pin, ukuze swing nezimo.I-valve yokunciphisa ingcindezi kufanele ifakwe iqonde epayipini elivundlile, futhi ungatsheli kunoma iyiphi indlela.

Ukufakwa kwe-2.Valve ngaphambi kokuhlolwa kwekhwalithi okudingekayo kungenziwa.

Imiphumela: Kungase kuholele ekusebenzeni kwesistimu yokushintshwa kwe-valve akuguquguquki, kuvalwe ngokukhululekile kanye nokuvuza kwamanzi (igesi), okuholela ekulungiseni kabusha, futhi kuthinte ngisho nokunikezwa kwamanzi okujwayelekile (igesi).

Izinyathelo: Ngaphambi kokufakwa kwe-valve, ukuhlolwa kwamandla okucindezelayo nokuqina kufanele kwenziwe.Ukuhlolwa kuzokwenziwa ngesampula engu-10% yenani leqoqo ngalinye (ibanga elifanayo, ukucaciswa okufanayo, imodeli efanayo), futhi kungabi ngaphansi kweyodwa.Ukuze ama-valve wesifunda avaliwe afakwe kwipayipi eyinhloko edlala indima yokusika, ukuhlolwa kwamandla nokuqina kufanele kwenziwe ngamunye ngamunye.Amandla evalvu nokucindezela kokuhlolwa kokuqina kuzohambisana nekhodi yokwamukela ikhwalithi.

3.I-Butterfly valve flange ene-valve flange evamile.

Imiphumela: usayizi we-valve flange we-butterfly uhlukile kulowo we-valve flange evamile.Amanye ama-flange anobubanzi obuncane bangaphakathi, futhi i-valve ye-butterfly flap inkulu, okuholela ekuhlulekeni ukuvula noma ukuvula kanzima i-valve.

Izinyathelo: I-Flange kufanele icutshungulwe ngokuvumelana nobukhulu bangempela be-valve flange ye-butterfly.
