Imisebenzi Eyinhloko Nezimiso Zokukhetha Zamavavu

Amavalvu ayingxenye ebalulekile yezinhlelo zamapayipi ezimbonini futhi adlala indima ebalulekile enqubweni yokukhiqiza.

Ⅰ. Umsebenzi oyinhloko we-valve

1.1 Ukushintsha nokusika imidiya:i-valve yesango, uvemvane valve, i-valve yebhola ingakhethwa;

1.2 Vimbela ukubuyela emuva kwe-medium:hlola i-valveingakhethwa;

1.3 Lungisa izinga lokucindezela kanye nokugeleza kwe-medium: i-valve yokuvala ongayikhetha kanye nevalvu yokulawula;

1.4 Ukuhlukaniswa, ukuxutshwa noma ukusatshalaliswa kwemidiya: i-plug valve,i-valve yesango, i-valve yokulawula ingakhethwa;

1.5 Vimbela ukucindezela okuphakathi ukuba kudlule inani elishiwo ukuze uqinisekise ukusebenza okuphephile kwepayipi noma imishini: i-valve yokuphepha ingakhethwa.

Ukukhethwa kwama-valve ikakhulukazi kumbono wokusebenza okungenazinkinga nomnotho.

Ⅱ. Umsebenzi we-valve

Kunezici ezimbalwa ezibalulekile ezihilelekile, futhi nansi ingxoxo enemininingwane ngazo:

2.1 Uhlobo loketshezi oludlulisayo

Uhlobo Loketshezi: Ukuthi uketshezi luwuketshezi, igesi, noma umhwamuko kuthinta ngokuqondile ukukhetha kwevalvu. Isibonelo, uketshezi lungase ludinge i-valve yokuvala, kuyilapho amagesi angase afaneleke kakhulu kuma-valve ebhola. Ukugqwala: Uketshezi olubolayo ludinga izinto ezimelana nokugqwala njengensimbi engagqwali noma ama-alloys akhethekile. I-Viscosity: Uketshezi olune-viscosity ephezulu lungadinga ububanzi obukhulu noma ama-valve aklanywe ngokukhethekile ukuze kuncishiswe ukuvala. Okuqukethwe kwe-particle: Uketshezi oluqukethe izinhlayiya eziqinile lungase ludinge izinto ezingagugi noma ama-valve aklanywe ngokukhethekile, njengama-pinch valves.

2.2 Umsebenzi wevalvu

Isilawuli sokushintsha: Ezikhathini lapho kudingeka umsebenzi wokushintsha kuphela, amavalvu ebhola nomaama-valve esangoyizinqumo ezivamile.

I-Flow Regulation: Uma kudingeka ukulawula ukugeleza okunembile, ama-valve eglobhu noma ama-valve okulawula afaneleka kakhulu.

Ukuvimbela Ukugeleza Kwasemuva:Hlola ama-valvezisetshenziselwa ukuvimbela uketshezi olubuyela emuva.

I-Shunt noma Hlanganisa: I-valve yezindlela ezintathu noma i-valve yezindlela eziningi isetshenziselwa ukuphambukisa noma ukuhlanganisa.

2.3 Usayizi wevalvu

Usayizi Wepayipi: Usayizi we-valve kufanele uhambisane nosayizi wepayipi ukuze kuqinisekiswe ukudlula koketshezi olubushelelezi. Izidingo zokugeleza: Ubukhulu be-valve budinga ukuhlangabezana nezidingo zokugeleza kwesistimu, futhi enkulu kakhulu noma encane kakhulu izothinta ukusebenza kahle. Isikhala Sokufaka: Imikhawulo yesikhala sokufaka ingaba nomthelela ekukhetheni usayizi wevalvu.

2.4 Ukulahlekelwa ukumelana nevalvu

Ukwehla kwengcindezi: I-valve kufanele inciphise ukwehla kwengcindezi ukuze igweme ukuthikameza ukusebenza kahle kwesistimu.

Idizayini yesiteshi esigelezayo: Ama-valve agcwele ama-bore, njengama-valve ebhola agcwele, anciphisa ukulahleka kokudonsa.

Uhlobo Lwevalvu: Amanye ama-valve, njengama-butterfly valves, anokumelana okuncane lapho evuliwe, okuwenza afanelekele izikhathi zokwehla komfutho ophansi.

2.5 Izinga lokushisa lokusebenza nokucindezela kokusebenza kwe-valve

Ibanga lokushisa: Izinto ze-valve zidinga ukujwayela izinga lokushisa loketshezi, futhi izinto ezimelana nezinga lokushisa zidinga ukukhethwa ezindaweni eziphakeme noma eziphansi.

Izinga lokucindezela: I-valve kufanele ikwazi ukumelana nokucindezela okukhulu kokusebenza kwesistimu, futhi uhlelo lokucindezela okuphezulu kufanele lukhethe i-valve enezinga eliphezulu lokucindezela.

Umthelela ohlanganisiwe wokushisa nokucindezela: Izinga lokushisa eliphezulu kanye nezindawo zokucindezela okukhulu zidinga ukucatshangelwa okukhethekile kwamandla wezinto ezibonakalayo kanye nezakhiwo zokuvala.

2.6 Impahla yevalvu

Ukumelana nokugqwala: Khetha izinto ezifanele ezisekelwe ekugqwaleni okuwuketshezi, njengensimbi engagqwali, i-Hastelloy, njll.

Amandla omshini: Impahla yevalvu idinga ukuba namandla anele emishini ukuze imelane nokucindezela kokusebenza.

Izinga lokushisa elivumelana nezimo: Izinto ezibonakalayo zidinga ukuzivumelanisa nezinga lokushisa lokusebenza, indawo yokushisa ephezulu idinga izinto ezikwazi ukumelana nokushisa, nendawo esezingeni eliphansi lokushisa idinga izinto ezikwazi ukumelana nokubanda.

Umnotho: Ngokwesisekelo sokuhlangabezana nezidingo zokusebenza, khetha izinto ezisetshenziswayo ezinomnotho ongcono.
