Ufake ivalvu entsha yePVC, kodwa ivuza rhoqo kwimisonto. Ngoku uvuza rhoqo okonakalisa umsebenzi wakho kwaye wonakalisa igama lakho kumthengi.

Thintela ukuvuza ngokusebenzisa ii-wraps ezi-5-8 zeteyiphu ye-PTFE, uqinise kuphela iinguqu ezi-1-2 ukudlula i-hand-tight, kwaye uqinisekise ukuba imisonto iyahambelana (NPT ukuya kwi-NPT). Ukuqinisa kakhulu kuyayiqhekeza ivalvu kwaye yeyona mpazamo ixhaphakileyo yokufaka.

Ndihlala ndixelela iqabane lam uMohommad ukuba uninzi "lweengxaki" zeevalvu zizinto ezingasebenzi kakuhle ekufakeni. Ukuthontsiza okuncinci okuvela kuqhagamshelo olunemisonto kunokuba yinto ecaphukisayo kakhulu, kodwa luphawu olucacileyo lokuba inyathelo elibalulekileyo liphoswe ngexesha lokuhlanganiswa. Ndibone iivalvu ezilungileyo zilahlwa ngenxa yempazamo elula yokufakela. Ukudibanisa kakuhle kwasekuqaleni konga ixesha elininzi, imali, kunye neengxaki. Makhe sijonge indlela yokwenza ngokugqibeleleyo ngalo lonke ixesha.

Ungayinqanda njani ivalvu yebhola ekuvuzeni kwimisonto?

Ukuvuza okungapheliyo okuvela kuqhagamshelo olutsha kuyacaphukisa. Usebenzise i-sealant, kodwa ukuvuza akuyeki, okulibazisa iprojekthi yakho kwaye kubangele umonakalo onokwenzeka emanzini.

Nqanda ukuvuza komsonto ngokujonga isicelo sakho sesitywini. Sebenzisa iteyiphu yePTFE esemgangathweni ophezulu, uyisonge izihlandlo ezi-5-8 kwicala lemisonto. Oku kuqinisekisa ukuba iteyiphu izalisa ngokufanelekileyo izikhewu ngaphandle kokutyhalelwa ngaphandle ngexesha lokuqinisa.

Kulapho uninzi lokuvuza kwemisonto luqala khona luze luphele khona. Imisonto enciphileyo kwi-PVC fitting ayenzelwanga ukwenza isitywino ngokwaso. Umsebenzi wayo kukudala amandla oomatshini. Isitywino sokwenyani senziwe yiisitywini somsonto. Iteyiphu ye-PTFE, ekwabizwa ngokuba yiTeflon tape, lolona khetho luqhelekileyo nolusebenzayo. Isitshixo sikwisicelo. Okokuqala, qiniseka ukuba imisonto yesilisa icocekile kwaye yomile ngokupheleleyo. Qala ukusonga kwintambo yesibini ukusuka esiphelweni. Oku kubalulekile ukuthintela nayiphi na iteyipu ukuba inganqunyulwa kwaye ityhalelwe kumbhobho, apho inokuvala inkqubo. Kufuneka uyisonge iteyipu ngokwewotshi, kwicala elifanayo oza kuyiqinisa i-fitting. Ukuba uyisonga ngokuchasene newotshi, isenzo esilula sokuyisonga i-fitting siya kubangela ukuba iteyipu iqokeleleke kwaye ivuleke. Kwizinto ezisemgangathweni ukusuka kwi-1/2″ ukuya kwi-1″, ii-wraps ezipheleleyo ezi-5 ukuya kwezi-8 zezona zifanelekileyo. Tsala iteyipu iqine njengoko uyisonga ukuze ingene kwiintlambo zemisonto. Kuya kufuneka ukwazi ukubona umphezulu wemisonto ngeteyipu.

Ungakuthintela njani ukuvuza kwevalvu ngaphambi kokufakwa?

Uza kudibanisa ivalvu, kodwa imisonto ivakala ngathi ayisebenzi kakuhle xa uyivavanya. Ukungayinaki le mvakalelo kunokukhokelela kunxibelelwano oluqhekekayo okanye oluvuzayo nokuba wenza ntoni na.

Thintela ukuvuza ngokuqinisekisa ukuba imisonto yakho iyahambelana ngaphambi kokuba uchukumise ne-sealant. Uninzi lwehlabathi lusebenzisa i-BSPT, ngelixa iMntla Melika isebenzisa i-NPT. Zifana kodwa azihambelani kwaphela kwaye ziya kuhlala zivuza.

Olu lolona vavanyo lubalulekileyo, kwaye ukungayifumani kuqinisekisa ukungaphumeleli. Njengoko mna noMohommad sixoxe ngemarike yaseBangladesh, uhlala ufumana zombini imigangatho ye-NPT kunye ne-BSPT ifumaneka. Ayinakutshintshwa.

• I-NPT (iTaper yeMibhobho yeSizwe):Le ntambo ine-engile yeedigri ezingama-60.
• I-BSPT (iBritish Standard Pipe Taper):Le ntambo ine-engile ye-55-degree.

Ukunyanzela i-NPT yesilisa kwivalvu ye-BSPT yesifazane yindlela yokulungisa intlekele. Ii-engile ezahlukeneyo zibangela ukuba zibopheke kwaye zinqamleze umsonto. Uqhagamshelo lusenokuvakala luqinile, kodwa wonakalisa nje iplastiki kwaye udala indlela yokuvuza ejikelezayo engenakulungiseka yi-sealant. Ngaphambi kokufakela, bamba i-fitting yesilisa kwi-port yevalvu yesifazane. Khangela iimpawu. Kwi-Pntek, siphawula ngokucacileyo iivalvu zethu ngohlobo lomsonto. Ukuba akukho zimpawu, zama ukuzidibanisa ngesandla ukuze ujike kube kanye okanye kabini. Ukuba uziva uxhathiso olukhulu okanye ushukuma, yeka ngoko nangoko. Ngokuqinisekileyo azifani. Olu vavanyo lwemizuzwana emihlanu luthintela enye yezona mpazamo zokufakelwa eziphazamisayo nezinokuphepheka ngokupheleleyo.

Kutheni ukuqinisa kakhulu kuyeyona ndlela imbi yokunyanga ivalvu evuzayo?

Ivalvu yakho iyavuza, ngoko ubamba isikrufu esikhulu ukuze uyijike kwakhona. Uva ukuqhekeka okubukhali, kwaye ngoku ukuvuza okuncinci kube kukusilela okukhulu, okungenakulungiswa.

Ukuqina kakhulu yeyona nto iphambili ebangela ukungasebenzi kakuhle kwevalvu yePVC. Isenzo se-wedge sentambo yesilisa enciphileyo siya kwahlukanisa i-port yePVC yesifazane. I-torque echanekileyo iqiniswa nje ngesandla, emva koko ijike ibe yi-1-2 kuphela ngesitshixo.

Yinto yemvelo: ukuba kukho into evuzayo, yiqinise ngakumbi.Iivalvu zePVC, le yinto engalunganga ukuyenza. Ngokungafaniyo nesinyithi, i-PVC yi-thermoplastic enokuqina okulinganiselweyo. Xa uqinisa i-tapered fitting (ingakumbi eyesinyithi) kwi-port ye-PVC yabasetyhini, ufaka i-wedge kwiplastiki. Oku kudala uxinzelelo olukhulu lwangaphandle, olwaziwa ngokuba yi-hoop stress. Akudingi mandla amaninzi ukudlula amandla okutsalwa kwe-PVC. Oku kubangela ukuba kubekho ukuqhekeka kweenwele ezantsi kwemisonto, ethi emva koko isasazeke phantsi koxinzelelo lwenkqubo. Umthetho esiwufundisayo ulula kwaye awuguquki:Isandla Esiqinileyo kunye neSijiko esinye ukuya kwesibini.Yiyo leyo. Sebenzisa isikrufu sentambo ukuba unako ukuze uphephe ukufaka uxinzelelo emzimbeni wevalvu. Isitywino senziwe yiteyiphu yePTFE ecinezelwa kwizithuba zemisonto, kungekhona ngokutyumza iplastiki ukuze ifakelwe. Ukuba iyavuza emva kokuqinisa ngokufanelekileyo, ingxaki ayikokuqina. Kufuneka urhoxise uqhagamshelo kwaye ujonge ezinye iingxaki ezifana nemisonto engahambelaniyo okanye iteyiphu enganeleyo.

Ziziphi iintsilelo ezintathu eziqhelekileyo ezivela ekufakweni kakubi?

Ujongene nokuphazamiseka kwevalvu kwindawo yokusebenza. Uhlala utshintsha iindawo, kodwa iingxaki ziyaqhubeka, zibiza ixesha, imali, kwaye zitshabalalisa ukuthembana komthengi wakho emsebenzini wakho.

Ezona ngxaki zintathu zixhaphakileyo zokufakelwa zezi: ii-ports eziqhekekileyo ngenxa yokuqina kakhulu; ukuvuza kwentambo okungapheliyo ngenxa yokusebenzisa imisonto ye-NPT/BSPT engahambelaniyo; kunye nomonakalo wangaphakathi wesitywina ngenxa yenkunkuma engena kwivalvu ngexesha lokufakwa.

Ukuqonda ezi mpazamo zintathu kukunceda ukuba wakhe uluhlu lokuhlola ngengqondo kuzo zonke izinto ezifakelweyo. Xa ivalvu enemisonto ingaphumeleli, phantse isoloko ingomnye walaba babangela iingxaki.

Loo mpazamo yesithathu idla ngokungananzwa. Ukuba ivalvu yebhola iba nzima ukuyijika okanye ivuza xa ivaliwe, kusenokwenzeka ukuba iqhekeza elincinci lenkunkuma likhukuliswe kwivalvu. Xa ibhola ivala kule nto iqinileyo, inokufaka umphezulu webhola yeplastiki ngokusisigxina okanye yonakalise izihlalo zePTFE ezithambileyo. Oku kudala indlela ehlala ivuza ngaphakathi kwivalvu. Soloko ugcina iivalvu zakho ezintsha kwiphakheji yazo kude kube lixesha lokufakelwa, kwaye soloko uhlambulula imigca ngaphambi kokuba uzifake. Imizuzwana embalwa yokhathalelo kwangaphambili ithintela iingxaki ezinkulu kamva.

Isiphelo

Thintela ukuvuza kwemisonto ngokuyifanisa imisonto, usebenzise i-sealant ngokuchanekileyo, kwaye uphephe ukuyiqinisa kakhulu. Ukufakela ngokufanelekileyo yimfihlo elula yokwenza imisonto ihlale ixesha elide, ihlale ixesha elide, kwaye ingavuzi.Ivalvu yebhola yePVCinkqubo.
