Udinga ukufaka i-PVC ball valve, kodwa ukunamathela okubi kungabangela ukuvuza. Leli phutha elilula lingonakalisa iphrojekthi yakho, lichithe izinto ezibizayo, futhi lonakalise idumela lakho kumakhasimende akho.

Ukuze unamathelise ivalvu yebhola le-PVC, faka i-primer ensomi ekugcineni kwepayipi nangaphakathi kwesokhethi yevalvu. Landela ngokushesha ngesendlalelo esikhulu sikasimende we-PVC kuzo zombili izingxenye. Faka ipayipi ngokugcwele kusokhethi ngokujika kwekota bese ulibamba ngokuqinile imizuzwana engama-30.

Eminyakeni edlule, ngibone ukufakwa okuningi, futhi i-valve enhle kakhulu ingahluleka ngenxa yejoyinti elilodwa elibi. Kuyinselele evamile abaphathi bokuthenga abanjengoBudi namaqembu akhe okufaka ababhekana nayo nsuku zonke. Inqubo ngokwayo ilula, kodwa isinyathelo ngasinye sibalulekile ekudaleni isibopho esizohlala amashumi eminyaka. Ukweqa isinyathelo esisodwa, noma ukusheshisa inqubo, umehluko phakathi kwe-uhlelo olungavuzikanye nokufona. Ake sihlukanise imininingwane ukuqinisekisa ukuthi konke ukuxhumana okwenzayo kuphelele.

Ingabe ama-valve ebhola le-PVC angavuza?

Uthemba ama-valve ebhola le-PVC ukuze avale kahle. Kodwa ukuconsa okuhamba kancane, okufihliwe kungabonakala amasonto amaningi, kubangele umonakalo wamanzi noma ukulahlekelwa umfutho wesistimu okubucayi okukhungathekisayo futhi okubiza kakhulu ukukuthola.

Yebo, amavalvu ebhola le-PVC angavuza ngokuphelele. Ukuvuza kuvame ukwenzeka emajoyintini ahlanganisiwe ngenxa yokunamathela okungafanele. Kungavuza futhi kusuka ekupakishweni kwesiqu sevalvu ngokuhamba kwesikhathi, noma kuhluleke ngaphakathi uma izivalo zonakele.

Uma ivalvu ivuza, cishe njalo ifika kwelinye lamaphuzu amathathu abuthakathaka. Engikubonayo kakhulu yijoyinti uqobo. Lokhu cishe njalo kuyiphutha lokufaka. Mhlawumbe umfakisi akasebenzisanga i-primer, noma akafakanga usimende owanele, noma wehlulekile ukubamba ijoyinti ndawonye isikhathi eside ngokwanele ukuze i-weld yamakhemikhali iqine. Kwa-Pntek, sifaka ama-socket ethu e-valve ngemishini ehlukahlukene.ukubekezelelana okuqinileukusiza ukuqinisekisa ukuthi ilingana kahle, okusiza ukunciphisa la maphutha. Indawo yesibili yokuvuza yisiqu. Ama-O-rings avala isibambo angaguga ngenxa yokusetshenziswa njalo noma anciphe ngenxa yamakhemikhali.Amavalvu ethusebenzisa ikhwalithi ephezuluAma-EPDM O-ringsfuthi ngokuvamile banomklamo ophindwe kabili ukuze banikeze ukuphepha okwengeziwe ekuvuthweni kwesiqu. Inkinga yesithathu ukuvuzangokusebenzisaivalvu uma ivaliwe. Lokhu kwenzeka lapho imfucumfucu efana nesihlabathi ibanjwa futhi iklwebha izihlalo zangaphakathi, noma izihlalo zimane ziguge uma ivalvu isezingeni eliphansi.

Ingabe i-PVC ayingenwa manzi ngo-100%?

Ucabanga ukuthi njengoba i-PVC iyipulasitiki, ayingenwa manzi nhlobo. Kodwa lokhu kucabanga kungaba yingozi uma ungaqondi ukulinganiselwa kwayo, okukuholela ekudaleni izinhlelo ezingase zihluleke ekugcineni.

Izinto eziqinile ze-PVC ngokwazo azingenwa manzi ngokuphelele futhi azinazo izimbobo. Kodwa-ke, i-PVC eqediweuhleloayingenwa manzi njengephuzu layo elibuthakathaka kakhulu—amalunga ahlanganiswe nge-solvent. Ilunga elenziwe kahle liyadingeka ngempela ukudala uhlelo olungangenwa manzi oluyi-100%.

Lona umehluko obaluleke kakhulu phakathi kwezinto zokwakha kanye nohlelo. Ungathatha ucezu lwepayipi le-PVC ulishiye licwiliswe emanzini amashumi eminyaka, futhi izinto ngokwazo ngeke zimunce amanzi noma zonakale. Liyi-polymer eqinile, engenazo izimbobo. Ubuthakathaka abuyona ipayipi noma izinto zokufaka, kodwa ukuxhumana phakathi kwazo okudalwe yithimba lakho.inqubo yesamente ye-solventngobuchwepheshe iwukushisela kwamakhemikhali. I-primer ihlanza indawo engaphezulu bese usimende uncibilikisa okwesikhashana izingcezu ezimbili zepulasitiki, uzihlanganise zibe yinye. Uma leyo weld ingaphelele ngenxa yokungcola, ukuntuleka kwesimende, noma ukungayibambi ngokuqinile, ingadala isiteshi esincane, esincane. Le siteshi ingase ingavuzi ngokucindezela okuphansi, kodwa uma uhlelo selucindezelwe ngokugcwele, amanzi azothola indlela yokudlula. Kumaqembu kaBudi e-Indonesia, kubalulekile futhi ukukhumbula ukuthi isimo sezulu esifudumele nesinomswakama siyathintaizikhathi zokuphulukisaIlunga lidinga ukuhlala lingaphazanyiswa isikhathi eside ngokwanele ukuze liqine ngokugcwele ngaphambi kokufakwa kwengcindezi.

Kungani ama-valve ebhola le-PVC ebhajwa?

Udinga ukuvala amanzi uma kunesimo esiphuthumayo, kodwa isibambo sevalvu ngeke sinyakaze. Ivalvu ebambekile ayisebenzi nhlobo uma uyidinga kakhulu futhi ingaguqula ukulungiswa okulula kube yiphrojekthi enkulu.

Amavalvu ebhola le-PVC avame ukubhajwa ngenxa yokusetshenziswa okungajwayelekile, okuvumela ukuthi amadiphozithi amaminerali akheke phakathi kwebhola nezivalo zalo. Ukuqinisa kakhulu ama-union nuts ku-union valve yangempela nakho kungabangela ukuthi ibopheke futhi kube nzima ukuyijika.

Lesi yisikhalazo senkonzo yokuqala mayelana nama-ball valve anoma iyiphi into. Isizathu esivame kakhulu silula—i-valve ayisetshenziswa. Amanzi, ikakhulukazi amanzi aqinile, aqukethe amaminerali ancibilikisiwe njenge-calcium. Uma i-valve ihlala endaweni efanayo evulekile unyaka wonke, la maminerali angangena kancane kancane futhi akheke phakathi kwebhola nezihlalo ze-PTFE, esebenza njengesamente. Indlela elula yokuvimbela lokhu “ukuzivocavoca” i-valve ngokuyivala nokuyivula kanye njalo ezinyangeni ezimbalwa. Lokhu kuqeda noma yikuphi ukwakheka okuncane. Esinye isizathu esivamile, ikakhulukaziama-valve e-union yangempela, iqinisa kakhulu. Ama-union nuts amakhulu akhona ukuvala umzimba we-valve esebenzisa ama-O-rings. Adinga ukuqina ngesandla kuphela kanye nokujika okuncane nge-wrench. Uma umfakisi ewacindezela nge-wrench enkulu, ucindezela wonke umzimba we-valve, acindezele ibhola ezihlalweni futhi enze kube nzima kakhulu ukulijika.Ama-valve e-Pntekzenzelwe ukuvala ngokuphelele ngaphandle kwalolu hlobo lwamandla amakhulu.

Ungazi kanjani ukuthi i-valve ye-PVC ayilungile?

I-valve ehlulekayo ingabukeka ilungile ngokuphelele uma ungaphandle. Ukungazi izimpawu zesixwayiso ezicashile kungaholela ekuhlulekeni okungazelelwe nokubi kakhulu, okubangela umonakalo wempahla nokuphazamisa isevisi yamakhasimende akho.

Ivalvu ye-PVC ayilungile uma ivuza emalungeni ayo noma esiqwini, yehluleka ukuvimba ngokuphelele ukugeleza kwamanzi uma ivaliwe, noma uma isibambo singenakwenzeka ukusijika. Noma yimiphi imifantu ebonakalayo emzimbeni wevalvu nayo iyisibonakaliso esicacile sokuthi idinga ukushintshwa ngokushesha.

Kubalulekile ukuthi amaqembu akho azi ukuthi yini okufanele ayibheke ngesikhathi sokuhlola okuvamile. Ukuhlola okumbalwa okulula kungavimbela inkinga enkulu kamuva. Okokuqala, hlola ngokucophelela okubonakalayo. Bheka noma yimiphi imifantu yezinwele, ikakhulukazi eduze kwezisekelo lapho kufakwa khona ipayipi. Lokhu kubangelwa ukucindezeleka futhi kuyisibonakaliso sokwehluleka okungenzeka. Futhi, hlola noma yikuphi ukushintsha kombala okuphawulekayo, okungase kusho ukuthi i-PVC iyonakala ngenxa yokuvezwa ngamakhemikhali noma ukukhanya kwe-UV. Okulandelayo, yenza ukuhlolwa okusebenzayo. Vala ivalvu bese ubona ukuthi amanzi asadlula yini. Lokhu "kuvuza" kusho ukuthi izihlalo zangaphakathi zonakele. Hlola noma yikuphi ukuvuza okuvela esiqwini sesibambo noma ezixhunyanisweni ezinamathiselwe. Ekugcineni, hlola ukusebenza kwesibambo. Kufanele siqine kodwa siphenduke kahle. Uma siqandisiwe ngokuphelele noma siqine kangangokuthi usengozini yokuphula isibambo, asithembekile futhi kufanele sishintshwe. Ivalvu esezingeni eliphezulu evela kumkhiqizi othembekile njengoPntek izoba nezindonga ezijiyile kanye nomklamo wesiqu oqinile, okwenza lokhu kwehluleka kube lula kakhulu.

Isiphetho

Ukunamathelisa ivalvu ye-PVC ngendlela efanele kubalulekile ohlelweni olungavuzi. Qaphela ukuthi amavalvu angavuza noma abhajwe, futhi wazi izimpawu ezibonakalayo zevalvu embi ukuze uvimbele ukwehluleka kwesikhathi esizayo.
