Iimpawu eziphambili kunye nokusetyenziswa kweevalvu zebhola

Iivalvu zebholaluhlobo lwevalvu yokujika ikota esebenzisa ibhola engenanto, eneembobo, nejikelezayo ukulawula ukuhamba kolwelo okanye iigesi kuyo. Xa ivalvu ivuliwe, umngxuma osebholeni uhambelana necala lokuhamba, okuvumela ukuba i-medium idlule. Xa ivalvu ivaliwe, ibhola ijikeleziswa ngama-90 degrees, ngoko umngxuma umi nkqo kumngxuma, uyivale. Isibambo okanye i-lever esetyenziselwa ukusebenzisa ivalvu idla ngokuhambelana nendawo yomngxuma, inika uphawu olubonakalayo lwemeko yevalvu.

Zithini iimpawu eziphambili zeevalvu zebhola:

1. UkuqinaIivalvu zebhola zaziwa ngobomi bazo obude kunye nokuthembeka kwazo, nangona zingasetyenziswa ixesha elide.
2. Ukusebenza ngokukhawulezaZingavulwa okanye zivalwe ngokukhawuleza ngokujika nje ngama-90 degrees.
3. Ukutywina OkuqinileyoIivalvu zebhola zibonelela ngeempawu ezintle zokutywina, nto leyo ezenza zilungele ukusetyenziswa okungekho mfuneko yokuba zivuza.
4. Ukuguquguquka: Banokusingatha uluhlu olubanzi lwezixhobo zokusasaza, kuquka ulwelo, iigesi, kunye ne-slurry.
5. Ukugcinwa Okuphantsi: Ngenxa yoyilo lwazo olulula, iivalvu zebhola azidingi ukugcinwa kakhulu.

Iintlobo zeeValve zeBhola:

1. I-Valve yeBhola yePort epheleleyo: Ubungakanani bebhore bufana nombhobho, nto leyo ebangela ukuba kubekho ilahleko encinci yokungqubana. Ilungele ukusetyenziswa okufuna ukuhamba okungenamkhawulo.
2. Ivalvu yeBhalbhu yePort encitshisiweyoUbungakanani bebhore buncinci kunepayipi, nto leyo enokubangela ukunqongophala kwamanzi kodwa incinci kwaye ingabizi kakhulu.
3. I-V-Port Ball Valve: Ibhola inembobo efana no-V, evumela ulawulo oluchanekileyo lokuhamba kwamanzi. Isetyenziswa rhoqo kwizicelo zokuqhobosha.
4. Ivalve yeBhola edadayo: Ibhola ayilungiswanga kwaye ibanjwe zizihlalo zeevalvu. Ifanelekile ukusetyenziswa ngoxinzelelo oluphantsi.
5. Ivalvu yeBhola yeTrunnion: Ibhola inamathele phezulu nasezantsi, nto leyo eyenza ukuba ifaneleke ukusetyenziswa ngoxinzelelo oluphezulu nobukhulu obukhulu.
6. Ivalvu yeBhola yeZibuko ezininzi: Iquka amazibuko amaninzi (ngesiqhelo amathathu okanye amane) okuhambisa okanye ukuxuba ukuhamba kwamanzi.

Izicelo:

Iivalvu zebhola zisetyenziswa kakhulu kumashishini ahlukeneyo, kuquka:

–Ioyile kunye neGesi: Ukulawula ukuhamba kweoyile ekrwada, igesi yendalo, kunye nezinye iihydrocarbon.
–Unyango lwamanzi: Kwimibhobho yamanzi okusela, amanzi amdaka, kunye neenkqubo zokunkcenkceshela.
–Ukucubungula iikhemikhali: Yokuphatha iikhemikhali ezirhabaxa neziyingozi.
–I-HVAC: Kwiinkqubo zokufudumeza, zokungenisa umoya, nezomoya opholileyo.
–Amayeza: Yeenkqubo ezicocekileyo nezingenazintsholongwane.
–Ukutya neZiselo: Kwimigca yokucubungula kunye nokupakisha.

Iingenelo zeevalvu zebhola:

–Ukulula kokusebenza: Kulula kwaye kuyakhawuleza ukuyivula okanye ukuyivala.
–Uyilo oluNcinci: Ithatha indawo encinci xa ithelekiswa nezinye iintlobo zeevalvu.
–Ukunyamezela Uxinzelelo Oluphezulu kunye noBushushu: Ifanelekile kwiindawo ezixineneyo.
–Ukuhamba kweendlela ezimbini: Iyakwazi ukusingatha ukuhamba kwamanzi kuzo zombini iindlela.

Iingxaki:

–Ayilungelanga Ukutshayela NgesihlunuNangona zinokusetyenziselwa ukuqhobosha, ukusetyenziswa ixesha elide kwiindawo ezivulekileyo kancinci kunokubangela ukuguguleka.
–Ulawulo Olulinganiselweyo Oluchanekileyo: Xa kuthelekiswa neevalvu zeglobhu okanye zeenaliti, iivalvu zebhola azinalawulo lokuhamba oluchanekileyo.

Izixhobo zeValve yeBhola:

Iivalvu zebhola zenziwe ngezinto ezahlukeneyo, kuquka:

–Yenziwe ngentsimbi eshayinayo: Ukumelana nokugqwala kunye nokuqina.
–Intsimbi yobhedu: Ngezicelo ezisetyenziswa ngokubanzi.
–I-PVC: Kwiindawo ezingcolisayo kunye nokusetyenziswa koxinzelelo oluphantsi.
–Intsimbi yeCarbon: Kwizicelo zoxinzelelo oluphezulu kunye nobushushu obuphezulu.

Izinto ekufuneka ziqwalaselwe xa ukhetha:

Xa ukhetha ivalvu yebhola, cinga ngezinto ezifana nezi:

– Uvavanyo loxinzelelo: Qinisekisa ukuba ivalvu iyakwazi ukumelana noxinzelelo lwenkqubo.
– Uluhlu lobushushu: Jonga ukuba ivalvu iyahambelana na nobushushu obusetyenziswayo.
– Ukuhambelana kweMedia: Qinisekisa ukuba izinto zevalvu ziyahambelana nolwelo okanye igesi ephathwayo.
– Ubungakanani kunye nohlobo lwePort: Khetha ubungakanani kunye nohlobo lweport olufanelekileyo kwisicelo sakho.

Iivalvu zebhola ziyindlela eguquguqukayo nethembekileyo yokukhetha izixhobo ezininzi zokulawula ulwelo, zibonelela ngokulinganisela kokusebenza, ukuqina, kunye nokulula kokusebenzisa.
