Ulwela ukwethemba ama-valve ebhola e-PVC kumaphrojekthi akho? Ukwehluleka okukodwa kungabangela umonakalo omkhulu kanye nokubambezeleka. Ukuqonda ukuthembeka kwawo kwangempela kubalulekile ekwenzeni isinqumo sokuthenga ngokuqiniseka.

Yebo, ama-valve ebhola le-PVC athembeke kakhulu ekusetshenzisweni kwawo okuhlosiwe, ikakhulukazi emanzini nasezinhlelweni zokunisela. Ukuthembeka kwawo kuvela ekwakhiweni okulula, kodwa kuncike kakhulu ekusetshenzisweni kwawo ngaphakathi kwezilinganiso zawo zokucindezela nokushisa ezifanele, ukufakwa okufanele, nokukhetha umenzi wekhwalithi.

Eminyakeni yami yokuphatha inkampani yokubumba nokuhweba, ngibe nezingxoxo eziningi mayelana nokuthembeka komkhiqizo. Ngivame ukucabanga ngoBudi, umphathi wokuthenga okhaliphile ovela kumsabalalisi omkhulu e-Indonesia. Wayenesibopho sokuthola ama-valve e-PVC amaningi, futhi ukukhathazeka kwakhe okukhulu kwakulula: “Kimmy, ngingawathemba lawa? Idumela lenkampani yami lincike ekhwalithini esiyinikezayo.” Wayedinga okungaphezu kokumane athi yebo noma cha. Wayedinga ukuqonda ukuthi “kungani” nokuthi “kanjani” ngemuva kokusebenza kwawo ukuze avikele ibhizinisi lakhe namakhasimende akhe. Lesi sihloko sichaza kahle lokho engabelana ngakho naye, ukuze nawe ukwazi ukuthola ngokuzethemba.

Ama-valve ebhola e-PVC athembeke kangakanani?

Uzwa izindaba eziphikisanayo mayelana nokusebenza kwevalvu ye-PVC. Ukukhetha ivalvu ngokusekelwe entengo kuphela kungaholela ekuhlulekeni kwangaphambi kwesikhathi kanye nokulungiswa okubizayo. Yazi imingcele yayo yangempela ukuqinisekisa impumelelo.

Amavalvu ebhola le-PVC athembeke kakhulu uma esetshenziswa kahle. Asebenza kahle kakhulu ngaphansi kuka-150 PSI kanye no-140°F (60°C). Ukwakheka kwawo okulula kuwenza aqine ezinsizeni ezinjengamanzi, kodwa awafanele uketshezi olushisa kakhulu, izinto ezihudulayo, noma amakhemikhali athile anolaka angalimaza i-PVC.

Lapho uBudi engibuza ngokuthembeka, ngamtshela ukuthi akucabange njengokukhetha ithuluzi elifanele lomsebenzi. Ngeke usebenzise isikulufu ukubethela isipikili. Ngokufanayo,Ukuthembeka kwevalvu ye-PVCkuyamangalisa, kodwa kungaphakathi kwefasitela layo lokusebenza eliklanywe kahle. Izingxenye ezibalulekile zisebenza ndawonye ukuze zilethe lokhu kusebenza. Umzimba we-PVC unikeza ubuqotho besakhiwo kanye nokumelana nokugqwala, kuyilapho izivalo zangaphakathi, ngokuvamile zenziwe ngeI-PTFE (i-Teflon), qinisekisa ukuthi ivaliwe kahle. Ama-stem O-rings, ngokuvamileI-EPDM noma i-Viton (FKM), vimbela ukuvuza endaweni yesibambo. Uma ukhetha i-valve kumkhiqizi odumile, lezi zinto zisezingeni eliphezulu futhi zihlangabezana nezindinganiso zomhlaba wonke njenge-ASTM, okuqinisekisa izinga elithile lokusebenza. Yilokhu kuhlanganiswa kwezinto zokwakha ezilula kanye nekhwalithi ezenza zibe umsebenzi othembekile ezimbonini eziningi kangaka.

Izinto Ezibalulekile Nokuklama

Ukuthembeka kuqala ngezinto zokwakha. I-PVC (i-Polyvinyl Chloride) imelana ngokwemvelo nokugqwala okuvela emanzini, usawoti, nama-asidi amaningi kanye nezisekelo. Ibhola elingaphakathi lijikeleza kahle ngokumelene nezihlalo ze-PTFE, into eyaziwa ngokungqubuzana kwayo okuphansi. Lokhu kusho ukuguguleka okuncane ngenxa yezinkulungwane zemijikelezo.

Imikhawulo Yokusebenza Ibalulekile

Ukwehluleka okuningi engikubonile kwenzeka lapho ivalvu icindezelwa ngaphezu kwemingcele yayo.

Kulula kakhulu ukuyifaka nokusebenza ngesibambo esilula sokujika ikota, okwenza kube ukukhetha okusebenzayo kakhulu nokunganakekeli kahle kwezinhlelo eziningi zokulawula uketshezi.

Kumphathi wokuthenga onjengoBudi, lezi zinzuzo zibhekana ngqo nezinselele zakhe eziyinhloko:ukuthuthukisa ukusebenza kahlefuthiizindleko zokuphathaLapho ethola ama-valve ezinkulungwane zamaphrojekthi, kusukela kumapayipi amancane ezindlu kuya ekuniseleni okukhulu kwezolimo, izinzuzoI-PVCkucace kakhulu. Izindleko eziphansi zimvumela ukuthi abe nokuncintisana kakhudlwana, kanti ukuthembeka engikushilo ekuqaleni kuqinisekisa ukuthi akabhekani nezikhalazo noma imbuyiselo eqhubekayo. Eminyakeni edlule, ngibone amakhasimende anjengoBudi esiza amakhasimende awo, osonkontileka, ukuthi onge isikhathi nemali eningi emisebenzini ngokushintshela ku-PVC lapho kufanele khona. Izinzuzo zidlulela ngale kwentengo yokuqala yokuthenga; zithinta lonke uchungechunge lokuhlinzeka, kusukela ekuthuthweni kwempahla kanye nezindawo zokugcina impahla kuya ekufakweni kokugcina. Kuyisinqumo esihlakaniphile esiletha inani kuzo zonke izinyathelo.

Ukusebenza Kahle Kwezindleko

Lena inzuzo esobala kakhulu. Ngosayizi ofanayo, ivalvu yebhola le-PVC ingaba yingxenyana yezindleko zevalvu yethusi noma yensimbi engagqwali. KuBudi, ukuthenga ngobuningi kusho ukuthi lokhu konga kukhulu kakhulu. Lokhu kuvumela inkampani yakhe ukuthi inikeze izinkontileka nabathengisi amanani ancintisanayo, ibasize bakhulise ukuthengisa.

Ukumelana Nokugqwala Okuphakeme

Esimweni sezulu esinomswakama njengase-Indonesia, ama-valve ensimbi angaba sengozini yokugqwala. I-PVC ayigqwali futhi imelana namakhemikhali ahlukahlukene. Lokhu kusho ukuthi izohlala isikhathi eside futhi ngeke idinge ukushintshwa, kunciphisa izindleko zesikhathi eside futhi kuqinisekiswe ubuqotho bohlelo.

Ukufakwa Nokusebenza Okulula

Ingabe ama-valve ebhola e-PVC ayahluleka?

Ukhathazeka ngokuthi kungenzeka ukuthi i-valve ihluleke ngokuzumayo, futhi ibe yinhlekelele. I-valve eyodwa embi ingamisa ukusebenza konke. Ungakugwema lokhu ngokuqonda ukuthi kungani nokuthi yehluleka kanjani.

Yebo, amavalvu ebhola le-PVC angahluleka futhi ayahluleka. Kodwa-ke, ukwehluleka cishe njalo kubangelwa yizici zangaphandle, hhayi iphutha kuvalvu uqobo. Izizathu ezivame kakhulu ukulimala ngokomzimba, ukusebenzisa ivalvu ngaphandle kwemingcele yayo yokucindezela noma yokushisa, ukungahambisani kwamakhemikhali, kanye nokuwohloka kwe-UV.

Ngake ngasebenza neklayenti kuphrojekthi enkulu yokunisela eyabhekana nochungechunge lokwehluleka. Wayekhungathekile, ecabanga ukuthi uthenge iqembu lama-valve elibi. Lapho ngiya endaweni, ngathola ukuthi inkinga kwakungewona ama-valve, kodwa ukufakwa. Izisebenzi zazisebenzisa ama-wren amakhulu futhi ziqinisa ama-valve anezintambo ngamandla amakhulu, okubangela ukuqhekeka kwezinwele emizimbeni yama-valve. Le mifantu emincane yayizohlala isikhashana kodwa izohluleka amasonto kamuva ngaphansi kwengcindezi yokusebenza evamile. Ngokunikeza ukuqeqeshwa okulula kokuqinisa izandla kanye nokujika kwekota, saqeda inkinga ngokuphelele. Lokhu kwangifundisa isifundo esibalulekile: ukwehluleka kuvame ukuba uphawu lwenkinga engavinjelwa. KuBudi, ukunikeza lolu hlobo lolwazi kumakhasimende akhe kwaba yindlela yokwengeza inani nokwakha ukwethembeka.

Amaphutha Okulimala Okungokwenyama kanye Nokufakwa

Lena imbangela yokuqala yokwehluleka engiyibonayo. Ukuqinisa kakhulu ukuxhumeka okunezintambo kuyiphutha elivamile. Okunye ukungavumeli ukusekelwa okufanele kwamapayipi, okubeka ingcindezi kuvalvu. Ukuqandisa nakho kuyisitha esikhulu; amanzi ayakhula uma eqandisa, futhi angaqhekeza kalula umzimba wevalvu yePVC ngaphakathi.

Ukuwohloka Kwezinto Ezibonakalayo

Ukugqokwa Kwesivalo Nokugqokwa Kwezingxenye

Nakuba ziqinile, izivalo zangaphakathi zingagcina zigugile ngemva kwezinkulungwane eziningi zemijikelezo, nakuba lokhu kuyinto engavamile ezicelweni eziningi. Ngokuvamile, imfucumfucu efana nesihlabathi noma uthuli ingena emgqeni bese iklwebha izihlalo ze-PTFE noma ibhola ngokwalo. Lokhu kudala indlela yokuthi amanzi angene ngayo ngisho nalapho ivalvu ivaliwe. Isihlungi esilula esisezansi singavimbela lolu hlobo lokwehluleka.

Yini ebangela ukuthi ivalvu yebhola le-PVC ivuza?

Ukuvuza kancane okuvela ku-valve kuyinkinga evamile kodwa engathi sína. Lokho kuvuza okuncane kungaholela ekulimaleni kwamanzi, ekulahlekelweni komkhiqizo, kanye nasezingozini zokuphepha. Ukuthola imbangela kubalulekile.

Ukuvuza kwamavalvu ebhola le-PVC kuvame ukubangelwa enye yezinto ezintathu: izivalo zangaphakathi ezonakele (izindandatho ze-O noma izihlalo), ukufakwa okungafanele okuholela ekuxhumekeni okubi, noma ukuqhekeka emzimbeni wevalvu uqobo. Ukungcola okungaphakathi kwevalvu nakho kungakuvimbela ukuthi kuvaleke ngokuphelele.

Uma ikhasimende libika ukuvuza, ngihlala ngibacela ukuthi bachaze ukuthi kuvelaphi. Indawo okuvuza kuyo ikutshela konke. Ingabe kuvuza lapho isibambo singena khona emzimbeni? Leyo yindlela yakudalainkinga ye-stem O-ring. Ingabe iyavuza lapho ivalvu ixhuma khona nepayipi? Lokho kukhomba iphutha lokufakwa. Noma ingabe amanzi asageleza lapho ivalvu ivaliwe? Lokho kusho ukuthi uphawu lwangaphakathi luphazamisekile. Ukuqonda lezi zinto ezihlukileamaphuzu okuvuzaKubalulekile ekuxazululeni izinkinga. Eqenjini likaBudi, ukukwazi ukubuza le mibuzo kubasiza ukuthi banikeze ukwesekwa kwamakhasimende okungcono, bebona ngokushesha ukuthi kuyinkinga yomkhiqizo (engavamile kakhulu) noma inkinga yokufaka noma yohlelo lokusebenza (evame kakhulu).

Ukuvuza Okuvela Esiqwini Sevalvu

Isiqu siwumshaft oxhumanisa isibambo nebhola. Sivalwa ngendandatho eyodwa noma ezimbili ze-O. Ngokuhamba kwesikhathi, noma ngokuchayeka kumakhemikhali angahambisani, lawa ma-O-ring angonakala futhi alahlekelwe ikhono lawo lokuvala, okubangela ukuconsa kancane okuvela eduze kwesibambo. Kwamanye ama-valve esitayela se-"true union", i-carrier nut ebambe i-stem assembly ingaqiniswa ukuze icindezele ama-O-rings futhi imise ukuvuza okuncane.

Ukuvuza Kwama-Connections

Lokhu kumayelana nokufakwa. Ekuxhumeni okune-solvent-weld (okunamathelisiwe), ukuvuza kwenzeka uma kusetshenziswe usimende ongafanele, uma ipayipi kanye nokufakwa kungahlanzwanga kahle, noma uma usimende unganikwanga isikhathi esanele sokuphola ngaphambi kokucindezela umugqa. Ekuxhumeni okunezintambo, ukuvuza kwenzeka ngenxa yokuqina okunganele, ukuqina ngokweqile (okubangela imifantu), noma ukungasebenzisi itheyiphu ye-PTFE eyanele ukuvala izintambo.

Ukuvuza Kudlule I-Ball Seal

Isiphetho

Ngamafuphi, ama-valve ebhola e-PVC anikeza ukuthembeka okuvelele kanye nenani uma esetshenziswa kahle. Ukuqonda imikhawulo yawo nokuqinisekisa ukufakwa okufanele kuyizihluthulelo zokusebenzisa amandla awo aphelele.
