Udinga ukulawula ukugeleza kwamanzi, kodwa bheka izinhlobo eziningi zama-valve. Ukukhetha okungalungile kungabangela ukuvuza, ukuvaleka, noma ukwehluleka ukulawula uhlelo lwakho ngendlela efanele, okuholela emonakalweni obiza kakhulu.

Kunezinhlobo eziningi zamavalvu e-PVC, kodwa ezivame kakhulu yilezi:amavalvu ebholaukulawula okuvula/okuvala,ama-valve okuhlolaukuvimbela ukugeleza kwegazi emuva, kanyeamavalvu esangoukuze kuhlukaniswe kalula. Uhlobo ngalunye lwenza umsebenzi ohlukile kakhulu ohlelweni lwamanzi.

Ukuqonda umsebenzi oyisisekelo wevalvu ngayinye kubalulekile. Ngivame ukusebenzisa isifaniso esilula lapho ngikhuluma nabalingani abanjengoBudi e-Indonesia. Ivalvu yebhola ifana nokushintsha kwesibani—ivuliwe noma icishiwe, ngokushesha. Ivalvu yesango ifana kakhulu nesithiyo esihamba kancane, esihlosiwe. Futhi ivalvu yokuhlola ifana nomnyango ohamba ngendlela eyodwa ovumela ithrafikhi ukuthi idlule ohlangothini olulodwa kuphela. Amakhasimende akhe—izinkontileka, abalimi, abafaki bamachibi okubhukuda—athola ukuthi lokhu kwenza kube lula kakhulu ukukhetha umkhiqizo ofanele. Uma usuwazi ukuthi yimuphi umsebenzi ivalvu okudingeka iwenze, ukukhetha kuyacaca.

Ingabe wonke ama-valve e-PVC afana?

Ubona amavalvu amabili ebhola le-PVC afanayo, kodwa elilodwa libiza kabili. Kuyayenga ukuthenga elishibhile, kodwa ukhathazekile ukuthi lizohluleka futhi libangele inhlekelele.

Cha, wonke ama-valve e-PVC awafani. Ahluke kakhulu ngekhwalithi yezinto ezibonakalayo, izinto zokuvala, ukwakheka, kanye nokunemba kokukhiqiza. Lokhu kwehluka kuthinta ngqo ukuthi i-valve ihlala isikhathi esingakanani nokuthi isebenza ngokwethembeka kangakanani ngaphansi kwengcindezi.

Umehluko phakathi kwevalvu enhle neyimbi usemininingwaneni ongeke uyibone njalo. Okokuqala yi-Izinto ze-PVCuqobo. Thina kwa-Pntek sisebenzisa i-PVC eyi-100% engeyona eyemvelo, eqinile, eqinile, futhi enesiphetho esicwebezelayo. Amavalvu ashibhile avame ukusebenzisa i-PVC ephinde yasetshenziswa exutshwe nama-filler afanai-calcium carbonateLokhu kwenza ivalvu ibe nzima, kodwa futhi ibe buthakathaka kakhulu futhi ithambekele ekuqhekekeni. Okulandelayo yilokhuizimpawuAmasongo amhlophe angaphakathi avala ibhola abizwa ngokuthi izihlalo. Amavalvu ekhwalithi asebenzisa okumsulwaI-PTFE (i-Teflon)ukuze kube nesivalo esibushelelezi, esithambile, nesihlala isikhathi eside. Ezishibhile zisebenzisa amapulasitiki asezingeni eliphansi aguga ngokushesha. Ama-O-ring amnyama esiqwini kufanele abe yi-EPDM, okuyinto enhle kakhulu ekumelaneni namanzi kanye ne-UV, hhayi irabha ye-NBR eshibhile. Ekugcineni, kuncike ekutheniukunemba. Ukukhiqiza kwethu okuzenzakalelayo kuqinisekisa ukuthi yonke ivalvu iphenduka kahle. Amavalvu enziwe kabi angaba lukhuni futhi kube nzima ukuwaphendula, noma akhululeke kangangokuthi azizwa engathembekile.

Yikuphi okungcono, i-PVC noma i-valve yensimbi?

Insimbi izwakala inzima futhi inamandla, kuyilapho i-PVC izwakala ilula. Ingqondo yakho ithi insimbi ihlala iyisinqumo esingcono, kodwa lokho kucabanga kungaholela ohlelweni oluhluleka ukugqwala.

Akukho okungcono; zakhiwe ngemisebenzi ehlukene. I-PVC ingcono kakhulu emanzini abandayo nasezindaweni ezigqwalayo lapho insimbi ingagqwala noma ibambe khona. Insimbi iyadingeka emazingeni okushisa aphezulu, ukucindezela okuphezulu, kanye namakhemikhali athile.

Ukukhetha phakathi kwe-PVC nensimbi akukhona ngamandla, kumayelana nekhemistri. Inzuzo enkulu ye-PVC ukuthi iyi-avikeleke ekugqwaleni nasekugqwaleni. UBudi unekhasimende embonini yezolimo zasemanzini elalivame ukushintsha amavalvu akhe ethusi minyaka yonke ngoba amanzi anosawoti ayewenza abambe. Selokhu ashintshela kumavalvu ethu e-PVC, ubengenazo izinkinga iminyaka emihlanu. Asebenza kahle njengosuku lokuqala. Yilapho i-PVC iphumelela khona: ukunisela ngomanyolo, amachibi okubhukuda, imigqa yamanzi anosawoti, kanye namapayipi ajwayelekile. Kodwa-ke, i-PVC inemingcele yayo. Ayikwazi ukusetshenziselwa amanzi ashisayo, njengoba izothamba futhi yehluleke. Iphinde ibe nezilinganiso zokucindezela eziphansi kunensimbi. Ivalvu yensimbi (njengensimbi noma ithusi) iyona kuphela ekhethwayo yemigqa yomusi, izinhlelo zamanzi ashisayo, noma izinhlelo zokusebenza zezimboni ezinomfutho ophezulu kakhulu. Isihluthulelo ukufanisa izinto zevalvu noketshezi olugeleza kuyo.

I-PVC vs. Insimbi: Yikuphi Okufanele Ukhethe?

Yini eyenza ivalvu ye-PVC 'enhle'?

Uyothenga ku-inthanethi bese uthola ivalvu ye-PVC ngentengo ephansi kakhulu. Uzibuza ukuthi ingabe ukuthenga ngokuhlakanipha noma ukuthi uthenga inkinga yesikhathi esizayo ezovuza ngo-2 ekuseni.

Ivalvu ye-PVC "enhle" yenziwe nge-PVC eyi-100% engeyona eyemvelo, isebenzisa izihlalo ze-PTFE zezinga eliphezulu kanye nama-EPDM O-rings, iphenduka kahle, futhi ihlolwe ingcindezi efektri ukuqinisekisa ukuthi ayivuzi.

Kunezinto ezimbalwa engitshela ithimba likaBudi ukuthi lizibheke. Okokuqala, hlolaumzimbaKufanele ibe nesiphetho esibushelelezi, esicwebezelayo kancane. Ukubukeka okufiphele, okufana ne-chalk kuvame ukubonisa ukusetshenziswa kwezithasiselo, okwenza iqhekeke. Okwesibili,sebenzisa isibambo. Kufanele ijike ngokumelana okubushelelezi nokungaguquguquki kusukela ekuvulekeni ngokuphelele kuya ekuvalekeni ngokuphelele. Uma iqine kakhulu, igobile, noma izwakala igcwele, ukwakheka kwangaphakathi akubi kahle. Lokhu kuholela ekuvuzeni kanye nesibambo esingaqhekeka. Okwesithathu, funaizimpawu ezicacile. Ivalvu yekhwalithi izophawulwa ngokucacile ngobukhulu bayo, isilinganiso sokucindezela (njenge-PN10 noma i-PN16), kanye nohlobo lwezinto (i-PVC-U). Abakhiqizi abadumile bayaziqhenya ngemininingwane yabo. Okokugcina, kuncike ekuthembeni. Kwa-Pntek, yonke ivalvu esiyenzayo ihlolwa ingcindezi ngaphambi kokuba iphume efektri. Lokhu kuqinisekisa ukuthi ngeke ivuze. Leso yisici esingabonakali osikhokhelayo: ukuthula kwengqondo ukuthi izosebenza nje.

Ingabe ivalvu entsha ye-PVC yenza umehluko?

Unevalvu endala eqinile ukuyijika noma enokuconsa kancane kakhulu. Kubonakala sengathi kuyinkinga encane, kodwa ukuyishaya indiva kungashiya uhlelo lwakho lusengozini yezinkinga ezinkulu.

Yebo, ivalvu entsha ye-PVC yenza umehluko omkhulu. Ithuthukisa ukuphepha ngokushesha ngokushintsha izinto ezibuthakathaka, iqinisekisa ukuvalwa okuphelele ukuvimba ukuvuza, futhi ihlinzeka ngokusebenza okubushelelezi nokuthembekile lapho uyidinga kakhulu.

Ukushintsha ivalvu endala akuyona nje indlela yokulungisa; kuyintuthuko enkulu ezindaweni ezintathu ezibalulekile. Okokuqalaukuphepha. Ivalvu ye-PVC ebilokhu iselangeni iminyaka iba buthakathaka. Isibambo singaphuka, noma okubi nakakhulu, umzimba ungaqhekeka ngenxa yokushayisana okuncane, okubangela isikhukhula esikhulu. Ivalvu entsha ibuyisela amandla okuqala ento. Okwesibiliukuthembeka. Ukuconsa kancane okuvela kuvalvu endala kungaphezu nje kwamanzi achithekile; kukhombisa ukuthi izivalo zangaphakathi zehlulekile. Ivalvu entsha enezihlalo ze-PTFE ezintsha kanye nama-EPDM O-rings inikeza ukuvala okuphelele, okuqinile okungama-bubble ongakuthembela kukho. Okwesithathu yilokhuukusebenza. Esimweni esiphuthumayo, udinga ukuvala amanzi ngokushesha. Ivalvu endala eqinile ngenxa yokuguga noma isikali ayisebenzi nhlobo. Ivalvu entsha iphenduka kahle, ikunikeza ukulawula okusheshayo. Ngezindleko ezincane ze-ivalvu, ubuyisela ukuphepha, ukuthembeka, kanye nomsebenzi wendawo yokulawula ebalulekile ohlelweni lwakho.

Isiphetho

OkuhlukileAmavalvu e-PVCyenza imisebenzi ethile. Ikhwalithi ichazwa yizinto zokwakha ezihlanzekile kanye nokukhiqizwa okunembile, okuqinisekisa impilo ende kakhulu futhi enokwethenjelwa kunenye indlela eshibhile.
