Udinga ukulawula ukuhamba kwamanzi kwinkqubo entsha yemibhobho. Ubona "i-PVC ball valve" kuluhlu lwezixhobo, kodwa ukuba awuyazi ukuba yintoni, awunakuqiniseka ukuba lolona khetho lufanelekileyo lomsebenzi.
Ivalvu yebhola yePVC yivalvu yeplastiki eqinileyo evalayo esebenzisa ibhola ejikelezayo enemingxuma kuyo ukulawula ukuhamba kolwelo. Yenziwe ngePolyvinyl Chloride, ifikeleleka ngexabiso eliphantsi kwaye imelana kakhulu nokugqwala kunye nokugqwala.
Le yimveliso yokuqala endiyazisa ngayo kumaqabane amatsha afana neBudi eIndonesia.Ivalvu yebhola yePVCsisiseko sezinto zanamhlanjeulawulo lwamanzi. Ilula, inokuthenjwa, kwaye iguquguqukayo kakhulu. Kumphathi wokuthenga onjengoBudi, ukuqonda okunzulu ngale mveliso iphambili kubalulekile. Akupheleli nje ekuthengeni nasekuthengiseni inxalenye; kukubonelela abathengi bakhe ngesisombululo esithembekileyo sayo yonke into ukusukaukunkcenkceshela ekhayaukuya kwiiprojekthi ezinkulu zemizi-mveliso. Intsebenziswano phakathi kwamaqela omabini iqala ngokuqonda iziseko kunye.
Yintoni injongo yevalvu yebhola yePVC?
Unombhobho kwaye kufuneka ulawule ukuba yintoni ehamba kuwo. Ngaphandle kwendlela ethembekileyo yokuthintela ukuhamba kwamanzi, naluphi na ulungiso okanye ukulungiswa kuya kuba yingxaki enkulu.
Eyona njongo iphambili yevalvu yebhola yePVC kukubonelela ngolawulo olukhawulezileyo nolupheleleyo lokuvula/ukucima kwinkqubo yolwelo. Ukujika ngokukhawuleza kwesiphatho kunokuma ngokupheleleyo okanye kuvumele ukuhamba ngokupheleleyo.
Cinga ngayo njengesibane sokukhanyisa amanzi. Umsebenzi wayo ophambili asikokulawula ubungakanani bokuhamba kwamanzi, kodwa kukuyiqala okanye ukuyimisa ngokufanelekileyo. Lo msebenzi ubaluleke kakhulu kwizicelo ezininzi. Umzekelo, abathengi bekontraka yaseBudi bayisebenzisa ukwahlula iindawo zenkqubo yokuhambisa amanzi. Ukuba isixhobo esinye sifuna ukulungiswa, banokuvala amanzi aye kuloo ndawo incinci endaweni yesakhiwo sonke. Ekunkcenkcesheleni, bawasebenzisa ukuqondisa amanzi kwiindawo ezahlukeneyo. Kumachibi nakwiispa, balawula ukuhamba kwamanzi ukuya kwiimpompo, kwiifilitha, nakwiiheater. Isenzo esilula nesikhawulezayo seivalvu yebholaiyenza ibe sisixhobo esibalulekileyo sokubonelela ngokuvala kakuhle, ukuqinisekisa ukhuseleko kunye nolawulo kuyo yonke inkqubo. KwaPntek, siyila iivalvu zethu ukuze zitywinwe kakuhle, ngoko ke xa ivaliwe, ihlala ivaliwe.
Ithetha ukuthini ibhola yePVC?
Uva igama elithi “ibhola yePVC” kwaye livakala lincinci okanye lidida. Usenokucinga ukuba libhekisa kwinxalenye eyahlukileyo, nto leyo eyenza kube nzima ukuqonda imveliso kwaye ubeke iodolo echanekileyo.
“Ibhola yePVC” ichaza iindawo ezimbini eziphambili zevalvu ngokwayo. “I-PVC” yinto, iPolyvinyl Chloride, esetyenziselwa umzimba. “Ibhola” yingqukuva ejikelezayo ngaphakathi ethintela ukuhamba kwamanzi.
Masichaze eli gama, njengoko ndihlala ndisenza kubathengisi abatsha bakaBudi. Ayinzima kangako njengoko ivakala.
- I-PVC (iPolyvinyl Chloride):Olu luhlobo oluthile lweplastiki eqinileyo neqinileyo eyenziwe ngayo umzimba wevalvu. Sisebenzisa iPVC kuba yinto entle kakhulu kwiinkqubo zamanzi. Ilula, nto leyo eyenza kube lula ukuyiphatha nokuyifaka. Ikwamelana ngokupheleleyo nokugqwala nokubola, ngokungafaniyo neevalvu zesinyithi ezinokonakala ngokuhamba kwexesha, ingakumbi ngeekhemikhali ezithile okanye amanzi aqinileyo. Okokugqibela, ixabisa kakhulu.
- Ibhola:Oku kubhekisa kwindlela esebenza ngayo ngaphakathi kwevalvu. Yingqukuva enomngxuma (i-port) ogqojozwe ngqo kuyo. Xa ivalvu ivuliwe, loo mngxuma uhambelana nombhobho. Xa ujika isiphatho, ibhola ijikeleza ngama-90 degrees, kwaye icala eliqinileyo lebhola livala umbhobho.
Ngoko ke, igama elithi “i-PVC ball valve” lithetha nje i-valve eyenziwe ngezinto ze-PVC esebenzisa indlela yebhola.
Yeyiphi ivalvu yebhola yebrass okanye yePVC engcono?
Ukhetha phakathi kwebronze nePVC kwiprojekthi ethile. Ukukhetha izinto ezingafanelekanga kunokukhokelela ekusileleni kwangethuba, ukugqithisa imali, okanye ukungcola, okubeka igama lakho emngciphekweni.
Akukho nanye kwezingcono; zenzelwe imisebenzi eyahlukeneyo. I-PVC ifanelekile kumanzi abandayo, iikhemikhali, kunye neeprojekthi ezixabisa kancinci kuba ayidli mhlwa kwaye ifikeleleka lula. I-brass ingcono kubushushu obuphezulu kunye noxinzelelo.
Lo ngumbuzo oqhelekileyo kubathengi bakaBudi, kwaye impendulo echanekileyo ibonisa ubuchule bokwenyani. Ukhetho luxhomekeke ngokupheleleyo kwiimfuno ezithile zesicelo. Ndisoloko ndicebisa ukusebenzisa itheyibhile elula yokuthelekisa ukuze isigqibo sicace.
| Uphawu | Ivalvu yeBhola yePVC | Ivalvu yeBhola yeBrass |
|---|---|---|
| Ukumelana nokugqwala | Igqwesile. Ayinawo umhlwa. | Kulungile, kodwa inokubola ngamanzi aqinileyo okanye iikhemikhali. |
| Ixabiso | Iphantsi. Ifikeleleka kakhulu. | Iphezulu. Ixabisa kakhulu kunePVC. |
| Umda woBushushu | Ezantsi. Ngokwesiqhelo ifikelela kwi-140°F (60°C). | Iphezulu. Iyakwazi ukuphatha amanzi ashushu kunye nomphunga. |
| Uvavanyo loxinzelelo | Ilungele uninzi lweenkqubo zamanzi. | Igqwesile. Iyakwazi ukumelana noxinzelelo oluphezulu kakhulu. |
| Ufakelo | Ilula. Isebenzisa isamente yePVC elula. | Inzima. Ifuna ukuthungwa kwemisonto kunye neebhloko zepayipi. |
| Eyona ilungileyo | Ukunkcenkceshela, amachibi okudada, unyango lwamanzi, imibhobho yamanzi ngokubanzi. | Imigca yamanzi ashushu, iinkqubo zoshishino ezinoxinzelelo oluphezulu. |
Kwimisebenzi emininzi yolawulo lwamanzi, i-PVC inika ulungelelwaniso olungcono lokusebenza kunye nexabiso.
Yintoni injongo yevalvu yePVC?
Ubona ivalvu yePVC njengento enye. Le mbono incinci inokubangela ukuba uphoswe ngumbono obanzi wokuba kutheni ukusebenzisa iPVC kwinkqubo yonke kuyindlela elungileyo.
Injongo yevalvu yePVC kukulawula ukuhamba kwamanzi kusetyenziswa izinto ezifikelelekayo, ezilula, nezingenamhlwa. Ibonelela ngesisombululo esithembekileyo nesihlala ixesha elide ngaphandle kweendleko okanye ubuthathaka beekhemikhali besinyithi.
Nangona umsebenzi wevalvu enye ikukuyeka amanzi, injongo yokukhethaI-PVCkuba loo valivu sisigqibo esibalulekileyo kwinkqubo yonke. Xa iprojekthi isebenzisa imibhobho yePVC, ukuyidibanisa neevalivu zePVC lolona khetho lukrelekrele. Kudala inkqubo engenamthungo nefanayo. Usebenzisa isamente efanayo yesolvent kuzo zonke iziqhagamshelo, nto leyo eyenza kube lula ukufakwa kwayo kwaye inciphise amathuba eempazamo. Ususa umngcipheko wokubaukugqwala kwe-galvanic, nto leyo enokwenzeka xa uqhagamshela iintlobo ezahlukeneyo zesinyithi kwipayipi. KuBudi njengomsasazi, ukugcina inkqubo yeepayipi zePVC, izixhobo, kunye neevalvu zethu zePntek kuthetha ukuba unokubonelela abathengi bakhe ngesisombululo esipheleleyo nesidibeneyo. Akupheleli nje ekuthengiseni ivalvu; kumalunga nokubonelela ngezinto zenkqubo yolawulo lwamanzi ethembekileyo, efikelelekayo, nehlala ixesha elide.
Isiphelo
A Ivalvu yebhola yePVCsisixhobo esingangeni mhlwa, esingabizi kakhulu sokulawula ukuhamba kwamanzi xa uvula/ucima. Uyilo lwaso olulula kunye neempawu ezintle zePVC zenza ukuba ibe lolona khetho luqhelekileyo kwiinkqubo zamanzi zanamhlanje.
