Ngaba iiValve zeBhola zingcono: xa kuthelekiswa nezinye iintlobo zeevalve

Ngaba ivalvu yebhola ingcono: Uthelekiso olupheleleyo neevalvu zesango, iivalvu zebhabhathane kunye neevalvu zeplagi

Xa kufikwa ekukhetheni ivalvu efanelekileyo yesicelo esithile, ukhetho lunokuba lukhulu. Iivalvu ezisetyenziswa kakhulu kumashishini ahlukeneyo ziquka iivalvu zebhola, iivalvu zesango, iivalvu zebhabhathane, kunye neevalvu zeplagi. Uhlobo ngalunye lwevalvu luneempawu zalo ezizodwa, izibonelelo kunye nokungalungi. Kweli nqaku, siza kuhlola umahluko phakathi kwezi valve, sigxile kule mibuzo ilandelayo: Ngaba ivalvu yebhola ingcono?

Ukuqonda iintlobo zeevalvu

1. Ivalvu yebhola

Ivalvu yebholayivalvu ejika ikota esebenzisa idiski engqukuva (ibhola) ukulawula ukuhamba kolwelo. Ibhola inomngxuma embindini ovumela ulwelo ukuba ludlule xa ivalvu ivuliwe. Xa ivalvu ivaliwe, ibhola ijikeleza ngama-90 degrees, ivale ukuhamba kolwelo. Iivalvu zebhola zaziwa ngokuqina kwazo, ukuthembeka kwazo, kunye nokukwazi kwazo ukubonelela ngotywino oluqinileyo.

Iingenelo zevalvu yebhola:

–Ukusebenza ngokukhawuleza: Kufuneka ikota yokujika ukuvula okanye ukuvala ivalvu yebhola, nto leyo eyenza ukuba ilungele ukusetyenziswa okufuna ukuvala ngokukhawuleza.

–Ukwehla koxinzelelo oluphantsi: Xa ivuliwe ngokupheleleyo, ivalvu yebhola ayiniki mandla kangako ekujikelezeni kwamanzi, nto leyo ebangela ukwehla koxinzelelo oluphantsi.

–Ukuqina: Ivalvu yebhola yenziwe ngezinto ezomeleleyo ezinokumelana noxinzelelo oluphezulu kunye nobushushu, ezifanelekileyo kwiintlobo ngeentlobo zezicelo.

2. Ivalvu yesango

Ivalvu yesangoyivalvu ejikelezayo ethe ngqo esebenzisa isango (okanye i-wedge) ukulawula ukuhamba kolwelo. Isango lihamba linyuka lize lihle ukuvula okanye ukuvala ivalvu. Iivalvu zesango zihlala zisetyenziswa kwiindawo apho ivalvu ivuleke ngokupheleleyo okanye ivaliwe ngokupheleleyo, njengoko zingenzelwanga ukugoba.

Iingenelo zevalvu yesango:

–Ukumelana okuncinci kokuhamba kwamanzi: Xa ivuliwe ngokupheleleyo, ivalvu yesango inika indlela yokuhamba ethe ngqo, nto leyo eyenza ukuba kubekho ukumelana okuncinci.

–Ifanelekile ukusetyenziswa koxinzelelo oluphezuluIivalvu zesango ziyakwazi ukumelana noxinzelelo oluphezulu kwaye zisetyenziswa kakhulu kwi-oyile negesi.

3. Ivalvu yebhabhathane

Ivalvu yebhabhathane yivalvu ejika ikota esebenzisa idiski ejikelezayo ukulawula ukuhamba kolwelo. Idiski ifakwe kwishaft kwaye ingajikeleziswa ukuvula okanye ukuvala ivalvu. Iivalvu zebhabhathane zihlala zisetyenziswa kwiindawo ezinkulu ngenxa yoyilo lwazo olukhaphukhaphu kunye nobukhulu obuncinci.

Iingenelo zevalvu yebhabhathane:

–Uyilo lokonga indawo: Iivalvu zebhabhathane zincinci kunezinye iintlobo zeevalvu, nto leyo eyenza ukuba zilungele ukusetyenziswa apho indawo incinci khona.

–Isebenza kakuhle emalini: Ngokubanzi, iivalvu zebhabhathane zibiza kancinci kuneevalvu zebhola kunye neevalvu zesango, nto leyo eyenza ukuba zibe lukhetho olungabizi kakhulu kwiindlela ezininzi.

4. Ivalvu yeplagi

Ivalvu yeplagi ifana nevalvu yebhola, kodwa isebenzisa iplagi esisilinda okanye enciphileyo ukulawula ukuhamba kwamanzi. Iplagi inomngxuma ohambelana nendawo yokungena kunye nendawo yokuphuma xa ivalvu ivuliwe. Iivalvu zeplagi zaziwa ngokulula kwazo kunye nokulula kokusetyenziswa.

Iingenelo zevalvu yeplagi:

–Uyilo olulula: Iivalvu zeplagi zinezinto ezimbalwa ezihambayo, nto leyo eyenza kube lula ukuzisebenzisa nokuzilungisa.

–Amandla Okutywina Alungileyo: Xa ivaliwe, i-stopcock inika isivalo esiqinileyo ukuthintela ukuvuza.

Ivalvu yebhola vs. ivalvu yesango

Xa uthelekisaiivalvu zebhola kunye neevalvu zesango, kukho izinto ezininzi ekufuneka ziqwalaselwe:

- Isantya sokuSebenzaIivalvu zebhola zisebenza ngokukhawuleza kuneevalvu zesango, nto leyo ezenza zilungele ukusetyenziswa kwezicelo ezifuna ukuvalwa ngokukhawuleza.

–Ulawulo lokuhamba kwamanzi: Nangona zombini iivalvu zinika ukumelana okuncinci nokuhamba kwamanzi xa zivuliwe ngokupheleleyo, iivalvu zebhola zibonelela ngolawulo olungcono kwiinkqubo zokuthomalalisa.

–Ukusebenza kokutywinaIivalvu zebhola zihlala zitywina ngcono kuneevalvu zesango, ngaloo ndlela zinciphisa umngcipheko wokuvuza.

Ngamafutshane, iivalvu zebhola zihlala zithathwa njengezingcono kuneevalvu zesango kwizicelo ezifuna ukusebenza ngokukhawuleza kunye nokutywinwa okuthembekileyo.

Ivalvu yebhola xa ithelekiswa nevalvu yebhabhathane

Uthelekiso lweevalvu zebhola kunye neevalvu zebhabhathane lubonisa umahluko olandelayo:

- Ubungakanani kunye nobunzima: Iivalvu zebhabhathane zihlala zikhaphukhaphu kwaye zincinci kuneevalvu zebhola, nto leyo eyenza kube lula ukuzifaka kwiindawo ezixineneyo.

–IxabisoIivalvu zebhabhathane zihlala zibiza kakhulu kuneevalvu zebhola, nto leyo eyenza ukuba zibe lukhetho oludumileyo kwiindlela ezinkulu zokusetyenziswa.
