Ngaba iiVave zeBhola zingcono: uthelekiso kunye nolunye uhlobo lwevalvu

Ngaba ivalve yebhola ingcono: Uthelekiso olubanzi kunye neevalvu zesango, iivalvu zebhabhathane kunye neevalvu zeplagi

Xa kuziwa ekukhetheni ivalve efanelekileyo kwisicelo esithile, ukhetho lunokuba lukhulu. Ezona zivalo zisetyenziswa kakhulu kumashishini ahlukeneyo abandakanya iivalve zebhola, iivalve zesango, iivalve zebhabhathane, kunye neeplagi zeplagi. Uhlobo ngalunye lwevalvu luneempawu zalo ezizodwa, iingenelo, kunye nokungalungi. Kweli nqaku, siza kuphonononga umahluko phakathi kwezi zivalo, sigxile kule mibuzo ilandelayo: Ngaba i-valve yebhola ingcono.

Ukuqonda iintlobo zevalvu

1. Ivalve yebhola

Ivalve yebholayivalve yekota esebenzisa idiski engqukuva (ibhola) ukulawula ukuhamba kolwelo. Ibhola inomngxuma embindini ovumela ulwelo ukuba ludlule xa ivalve ivuliwe. Xa i-valve ivaliwe, ibhola ijikeleza i-90 degrees, ivimbela ukuhamba kwamanzi. Iivalve zebhola ziyaziwa ngokuhlala kwazo, ukuthembeka, kunye nokukwazi ukubonelela ngetywina eliqinileyo.

Uncedo lwevalvu yebhola:

-Ukusebenza ngokukhawuleza: Kuphela ikota yokujika iyafuneka ukuvula okanye ukuvala ivalve yebhola, iyenze ilungele izicelo ezifuna ukuvalwa ngokukhawuleza.

-Ukwehla koxinzelelo oluphantsi: Xa ivuliwe ngokupheleleyo, i-valve yebhola inikezela ukuchasana okuncinci ukuhamba, okubangelwa ukuhla koxinzelelo oluphantsi.

-Ukuqina: I-valve yebhola yenziwe ngezinto ezinamandla ezinokumelana noxinzelelo oluphezulu kunye nobushushu, obufanelekileyo kwizicelo ezahlukeneyo.

2. Ivalve yesango

Ivalve yesangosisivalufa sentshukumo esisemgceni esebenzisa isango (okanye iweji) ukulawula ukuhamba kolwelo. Isango linyuka lisihla ukuze livule okanye livale ivalve. Iivalve zesango zidla ngokusetyenziswa kwizicelo apho ivalve ivuleke ngokupheleleyo okanye ivalwe ngokupheleleyo, njengoko ingeyilelwe ukuba iguqe.

Izinto ezilungileyo zevalve yesango:

-Ubuncinci bokuchasa ukuqukuqela: Xa ivuliwe ngokupheleleyo, i-valve yesango inikeza indlela yokuhamba ngokuthe tye, idala ukuchasana okuncinci.

-Ifanelekile kwizicelo zoxinzelelo oluphezulu: Iivalve zesango ziyakwazi ukumelana noxinzelelo oluphezulu kwaye zisetyenziswa ngokuqhelekileyo kwizicelo zeoli kunye negesi.

3. Ivalve yebhabhathane

Ivalve yebhabhathane yivalve yekota yokujika esebenzisa idiski ejikelezayo ukulawula ukuhamba kolwelo. I-disc ifakwe kwi-shaft kwaye inokujikelezwa ukuvula okanye ukuvala ivalve. Iivalvu zebhabhathane ziqhele ukusetyenziswa kwizicelo ezinkulu ngenxa yoyilo lwazo olukhaphukhaphu kunye nobukhulu obubambeneyo.

Izinto ezilungileyo zevalve yebhabhathane:

-Uyilo olugcina indawo: Iivalve zebhabhathane zixinene ngakumbi kunezinye iindidi zeevalvu, zizenza zilungele usetyenziso apho indawo incinyiweyo.

-Isebenza kakuhle emalini: Ngokuqhelekileyo, iivalve ze-butterfly zibiza kakhulu kuneebhola zebhola kunye nezivalo zesango, okwenza kube yinto engabizi kakhulu kwizicelo ezininzi.

4. Ivalve yokuplaga

Ivalve yeplagi iyafana nevalve yebhola, kodwa isebenzisa iplagi eyicylindrical okanye tapered ukulawula ukuhamba. Iplagi inomngxuma ohambelana nendawo yokungena kunye nokuphuma xa ivalve ivuliwe. Iivalve zeplagi ziyaziwa ngokulula kwazo kunye nokusebenziseka ngokulula.

Izinto ezilungileyo zevalve yeplagi:

-Uyilo olulula: Iivalve zeplagi zineendawo ezimbalwa ezihambayo, ezenza kube lula ukusebenza nokugcina.

-Ubuchule bokutywina obulungileyo: Xa ivaliwe, istopcock sinika itywina eliqinileyo ukuthintela ukuvuza.

Ivalve yebhola Vs. ivalve yesango

Xa uthelekisaiivalve zebhola kunye neevalve zesango, kukho izinto ezininzi ekufuneka ziqwalaselwe:

- Isantya sokuSebenza: Iivalvu zebhola zisebenza ngokukhawuleza kuneevalvu zesango, zizenza zifaneleke ngakumbi izicelo ezifuna ukuvalwa ngokukhawuleza.

-Ulawulo lokuqukuqela: Ngelixa zombini iivalve zinika ukuchasana okuncinci ukuhamba xa zivuleke ngokupheleleyo, iivalve zebhola zibonelela ngolawulo olungcono kwizicelo zokubetha.

-Ukusebenza kokutywina: Iivalvu zebhola ngokubanzi zinokutywinwa okungcono kuneevalvu zesango, ngaloo ndlela zinciphisa umngcipheko wokuvuza.

Isishwankathelo, iivalve zebhola ngokuqhelekileyo zibhekwa njengezona ziphezulu kuneengcango zesango kwizicelo ezifuna ukusebenza ngokukhawuleza kunye nokutywinwa okuthembekileyo.

Ivalve yebhola Vs. ivelufa butterfly

Ukuthelekisa iivalvu zebhola kunye neevalve zebhabhathane kuqaqambisa le mahluko ulandelayo:

- Ubungakanani kunye nobunzima: Iivalve zebhabhathane zikhaphukhaphu kwaye zixinene ngakumbi kuneevalve zebhola, nto leyo eyenza kube lula ukuzifaka kwiindawo ezixineneyo.

-Iindleko: Iivalve zebhabhathane ngokuqhelekileyo zineendleko eziphezulu kuneevalve zebhola, nto leyo ezenza zibe lukhetho oludumileyo kwizicelo ezinkulu.

-Ulawulo lokuqukuqela: Xa kuthelekiswa ne-butterfly valves, iivalve zebhola zinolawulo olungcono lokuhamba kunye nokukwazi ukutywina, ngokukodwa kwizicelo zoxinzelelo oluphezulu.

Ngelixa iivalve zebhabhathane zinokuthi zilungele ngakumbi izicelo ezithile, iivalve zebhola zikhethwa ngokutywinwa kwazo okuphezulu kunye nolawulo lokuhamba.

Ivalve yebhola Vs. ivalve yeplagi

Xa uthelekisa iivalve zebhola kunye neeplagi, qwalasela oku kulandelayo:

- Ukuntsonkotha koYilo: Uyilo lwevalve yebhola lunzima ngakumbi kune-valve yeplagi, eyenza ukuba kubize kakhulu ukuvelisa.

-Ukutywinwa kokuSebenza: Zombini iivalve zinekhono lokutywina elilungileyo, kodwa iivalve zebhola ngokubanzi zinomsebenzi ongcono kwizicelo zoxinzelelo oluphezulu.

-Ukusebenza: Iivalve zebhola zisebenza ngokukhawuleza xa kuthelekiswa neeplagi zeplagi, ezinokufuna umgudu ongakumbi wokuguqula iplagi.

Kwiimeko ezininzi, iivalve zebhola zikhethwa ngaphezu kweeplagi zeplagi ngenxa yokusebenza kwazo okuphezulu kunye nokulula kokusetyenziswa.

Ngaba ivalve yebhola ingcono

Ingaba i-valve yebhola ingcono kunezinye iintlobo zeevalve kuxhomekeke kwisicelo esithile kunye neemfuno. Nantsi eminye imiba ephambili:

1. IiMfuno zesicelo

3. Ukuqwalaselwa kweendleko

- Utyalo-mali lokuqala: Nangona iivalve zebhola zinexabiso eliphezulu lokuqala xa kuthelekiswa nezinye iintlobo zeevalve, ukuqina kwazo kunye neemfuno eziphantsi zokugcinwa kwazo kunokugcina iindleko kwixesha elide.

Ukuququmbela

Isishwankathelo, iivalve zebhola zibonelela ngeenzuzo ezininzi ngaphezu kwesango, ibhabhathane, kunye neeplagi zeplagi, ngakumbi kwizicelo ezifuna ukusebenza ngokukhawuleza, ukutywinwa okuthembekileyo, kunye noxinzelelo oluphezulu. Ngelixa uhlobo lwevalve nganye luneempawu zalo ezikhethekileyo kunye neenzuzo, iivalve zebhola ngokuqhelekileyo zithathwa njengelona khetho lufanelekileyo kwizicelo ezininzi zamashishini. Xa ukhetha i-valve, kubalulekile ukuqwalasela iimfuno ezithile zesicelo, kubandakanywa uxinzelelo, ukushisa, iimfuno zokulawula ukuhamba, kunye nemiqobo yebhajethi. Ekugqibeleni, ukhetho oluchanekileyo lwevalve luya kuxhomekeka kwiimfuno ezizodwa zenkqubo apho i-valve iya kusetyenziswa.

Njengomvelisi ohamba phambili e-China, siyakuqonda ukubaluleka kokukhetha ivalve efanelekileyo kwiimfuno zakho.
