Imisebenzi Eyinhloko Nezimiso Zokukhetha Ama-Valve

Ama-valve ayisici esibalulekile sezinhlelo zamapayipi ezimboni futhi adlala indima ebalulekile enqubweni yokukhiqiza.

ⅠUmsebenzi oyinhloko we-valve

1.1 Ukushintsha nokunqamula imidiya:ivalvu yesango, ivalvu yebhabhathane, i-valve yebhola ingakhethwa;

1.2 Vimbela ukugeleza emuva kwe-medium:ivalvu yokuhlolaingakhethwa;

1.3 Lungisa ingcindezi kanye nesivinini sokugeleza kwe-medium: i-valve yokuvala kanye ne-valve yokulawula ongayikhetha;

1.4 Ukuhlukanisa, ukuxuba noma ukusatshalaliswa kwemidiya: i-plug valve,ivalvu yesango, i-valve yokulawula ingakhethwa;

1.5 Vimbela ingcindezi ephakathi nendawo ukuthi ingadluli inani elibekiwe ukuqinisekisa ukusebenza okuphephile kwephayiphi noma imishini: ivalvu yokuphepha ingakhethwa.

Ukukhethwa kwama-valve kusekelwe kakhulu ekusebenzeni okungenazinkinga kanye nokonga.

ⅡUmsebenzi wevalvu

Kunezici eziningana ezibalulekile ezihilelekile, futhi nansi ingxoxo eningiliziwe ngazo:

2.1 Uhlobo loketshezi oludlulisa

Uhlobo Loketshezi: Ukuthi uketshezi luwuketshezi, igesi, noma umhwamuko kuthinta ngqo ukukhetha kwevalvu. Isibonelo, uketshezi lungadinga ivalvu yokuvala, kuyilapho amagesi angafaneleka kakhulu kumavalvu ebhola. Ukugqwala: Uketshezi olugqwala ludinga izinto ezingagqwali njengensimbi engagqwali noma ama-alloy akhethekile. Ukugqwala: Uketshezi olugqwala lungadinga ububanzi obukhulu noma amavalvu aklanywe ngokukhethekile ukuze kuncishiswe ukuvaleka. Okuqukethwe kwezinhlayiya: Uketshezi oluqukethe izinhlayiya eziqinile lungadinga izinto ezingagqwali noma amavalvu aklanywe ngokukhethekile, njengamavalvu okuncinza.

2.2 Umsebenzi wevalvu

Ukulawula ukushintsha: Ezimweni lapho kudingeka khona umsebenzi wokushintsha kuphela, ama-valve ebhola nomaamavalvu esangokuyizinketho ezivamile.

Ukulawulwa Kokugeleza: Uma kudingeka ukulawulwa kokugeleza okunembile, ama-valve embulunga noma ama-valve okulawula afaneleka kakhulu.

Ukuvimbela Ukugeleza Kokubuyela Emuva:Hlola ama-valvezisetshenziselwa ukuvimbela ukubuyela emuva koketshezi.

I-Shunt noma i-Merge: I-valve enezindlela ezintathu noma i-valve enezindlela eziningi isetshenziselwa ukuphambukisa noma ukuhlanganisa.

2.3 Usayizi wevalvu

Usayizi Wepayipi: Usayizi wevalvu kufanele uhambisane nosayizi wepayipi ukuqinisekisa ukuthi uketshezi luhamba kahle. Izidingo zokugeleza: Usayizi wevalvu udinga ukuhlangabezana nezidingo zokugeleza kwesistimu, futhi inkulu kakhulu noma incane kakhulu izothinta ukusebenza kahle. Indawo Yokufaka: Imikhawulo yesikhala sokufaka ingathinta ukukhethwa kosayizi wevalvu.

2.4 Ukulahlekelwa ukumelana kwevalvu

Ukwehla kwengcindezi: Ivalvu kufanele inciphise ukwehla kwengcindezi ukuze igweme ukuthinta ukusebenza kahle kwesistimu.

Umklamo wesiteshi sokugeleza: Amavalvu agcwele, njengamavalvu ebhola agcwele, anciphisa ukulahleka kokuhudula.

Uhlobo Lwevalvu: Amanye amavalvu, njengamavalvu ebhabhathane, anokumelana okuncane uma evulwa, okwenza afaneleke ngezikhathi zokwehla komfutho ophansi.

2.5 Izinga lokushisa lokusebenza kanye nengcindezi yokusebenza yevalvu

Ububanzi Bezinga Lokushisa: Izinto zevalvu kudingeka zivumelane nezinga lokushisa loketshezi, kanti izinto ezingamelana nezinga lokushisa kudingeka zikhethwe ezindaweni ezishisa kakhulu noma eziphansi.

Izinga lokucindezela: Ivalvu kufanele ikwazi ukumelana nokucindezela okuphezulu kokusebenza kwesistimu, kanti uhlelo lokucindezela okuphezulu kufanele lukhethe ivalvu enezinga lokucindezela okuphezulu.

Umthelela ohlangene wokushisa nokucindezela: Izindawo zokushisa okuphezulu nokucindezela okuphezulu zidinga ukucatshangelwa okukhethekile kwamandla ezinto zokwakha kanye nezakhiwo zokuvala.

2.6 Izinto zevalvu

Ukumelana nokugqwala: Khetha izinto ezifanele ngokusekelwe ekugqwaleni koketshezi, njengensimbi engagqwali, i-Hastelloy, njll.

Amandla omshini: Izinto zevalvu kudingeka zibe namandla omshini anele ukuze zikwazi ukumelana nengcindezi yokusebenza.

Ukuzivumelanisa nezimo zokushisa: Izinto ezisetshenziswayo zidinga ukuzivumelanisa nezimo zokushisa ezisebenzayo, indawo yokushisa ephezulu idinga izinto ezingamelani nokushisa, kanti indawo yokushisa ephansi idinga izinto ezingamelani nokubanda.

Umnotho: Ngenxa yokuhlangabezana nezidingo zokusebenza, khetha izinto ezisebenza kahle.
