Ufake ivalvu entsha yePVC eneentambo ngononophelo, kodwa ithontsiza kancinci kancinci kwimisonto. Ukuyiqinisa ngakumbi kuvakala kuyingozi, njengoko usazi ukuba ukujika kube kanye kakhulu kunokuphazamisa indawo yokufaka.

Ukuze ufake ngempumelelo ivalvu yebhola yePVC eneentambo, songa imisonto yesilisa ngeeleya ezi-3-4 zeteyipu yeTeflon. Soloko uyisonge ngendlela yokuqinisa. Emva koko, yiqinise ngesandla, kwaye usebenzise isikrufu ukujika kokugqibela kube kanye okanye kabini.

Intambo evuzayo yenye yezona ngxaki zixhaphakileyo nezibangela ukudideka ekufakeni. Phantse rhoqo ibangelwa yimpazamo encinci, enokuphepheka ekulungiseleleni okanye ekuqiniseni. Ndihlala ndixoxa ngale nto neqabane lam e-Indonesia, iBudi, kuba yingxaki engapheliyo abathengi bakhe abajongene nayo. Uqhagamshelo olukhuselekileyo nolungenamsonto kulula ukulufikelela. Kufuneka ulandele amanyathelo ambalwa alula, kodwa abaluleke kakhulu. Masiqwalasele imibuzo ephambili ukuze silungise ngalo lonke ixesha.

Ungazifakela njani izixhobo zombhobho wePVC ezifakwe imisonto?

Usebenzise intlama yokutywina imisonto esebenza kakuhle kwisinyithi, kodwa i-PVC fitting yakho isavuza. Okubi nangakumbi, ukhathazekile kukuba iikhemikhali ezikwintlama zingonakalisa iplastiki ngokuhamba kwexesha.

Kwi-PVC enemisonto, sebenzisa iteyiphu yeTeflon endaweni ye-pipe dope okanye i-paste rhoqo. Songa imisonto yesilisa izihlandlo ezi-3-4 kwicala elifanayo, uya kuyiqinisa i-fitting, uqinisekise ukuba iteyiphu ilala ithe tyaba kwaye igudileyo ukuze ivale kakuhle.

Lo mahluko phakathi kweteyiphu nentlama ubalulekile kwiifatyi zeplastiki.iipayipi zepayipiziqulathe iikhompawundi ezisekelwe kwi-petroleum ezinokuhlasela i-PVC ngeekhemikhali, nto leyo eyenza ukuba ibe buthathaka kwaye iqhekeke phantsi koxinzelelo oluqhelekileyo lokusebenza.Iteyiphu yeTeflonKwelinye icala, ayisebenzi ngokupheleleyo. Isebenza njengesitywini kunye nesithambisi, igcwalisa izikhewu ezincinci kwimisonto ngaphandle kokudala uxinzelelo oluyingozi olunokwenziwa yintlama. Oku kuthintela uxinzelelo ekufakweni kwebhinqa.

Ukukhetha iSealant kwiMisonto yePVC

Xa usonga imisonto, soloko usiya kwicala elijikajikayo njengoko ujonge esiphelweni sokufakelwa. Oku kuqinisekisa ukuba njengoko uqinisa ivalvu, iteyiphu iyagudiswa endaweni yokuba ihlanganiswe ize ivuleke.

Ungayifakela njani ivalvu yebhola kwipayipi yePVC?

Unevalvu yebhola enemisonto kodwa umbhobho wakho uthambile. Kufuneka uyidibanise, kodwa uyazi ukuba awukwazi ukuncamathisela imisonto okanye ukufaka umbhobho othambileyo. Yeyiphi indlela efanelekileyo yokufaka?

Ukuze uqhagamshele ivalvu yebhola eneentambo kumbhobho wePVC ogudileyo, kufuneka uqale ngokuncamathisela iadaptha yePVC eneentambo zesilisa kumbhobho. Emva kokuba isamente ipholile ngokupheleleyo, ungayifaka ivalvu eneentambo kumbhobho.

Awunakuze wenze imisonto kumbhobho wePVC oqhelekileyo nogudileyo; udonga luncinci kakhulu kwaye luza kusilela ngoko nangoko. Uqhagamshelo kufuneka lwenziwe nge-adaptha efanelekileyo. Kulo msebenzi, udinga i-I-adaptha yamadoda ye-PVC(edla ngokubizwa ngokuba yi-MPT okanye i-adaptha ye-MIPT). Elinye icala linesokhethi egudileyo, kwaye elinye linemisonto yamadoda ebunjiweyo. Usebenzisa inkqubo eqhelekileyo ye-PVC primer kunye nesamente ukutshixa isiphelo sesokhethi ngekhemikhali kumbhobho wakho, udale isiqwenga esinye, esidibeneyo. Isitshixo apha kukunyamezela. Kufuneka uvumele okounyango lwe-solvent-weldngokupheleleyo ngaphambi kokufaka nayiphi na i-torque kwimisonto. Ukusebenzisa amandla kwangethuba kakhulu kunokwaphula i-chemical bond entsha, kwenze ukuvuza kwindawo edibeneyo. Ndisoloko ndicebisa abathengi bakaBudi ukuba balinde ubuncinane iiyure ezingama-24 ukuze bakhuseleke.

Ungayifakela njani ivalvu enemisonto?

Uqinise ivalvu yakho entsha enemisonto de yavakala ngathi iqinile, kodwa weva nje ukuqhekeka okukruqulayo. Ngoku ivalvu yonakele, kwaye kufuneka uyinqumle uze uqale phantsi.

Indlela echanekileyo yokuqinisa "kukuqinisa ngesandla kunye nokujika kube kanye ukuya kabini." Yijije nje ivalvu ngesandla ide iqine, uze usebenzise isikrufu ukuyijika kube kanye okanye kabini okokugqibela. Yima apho.

Ukuqina kakhulu yeyona nto iphambili ebangela ukungasebenzi kakuhle kwezixhobo zeplastiki ezinemisonto. Ngokungafaniyo nesinyithi, esinokolula size sitshintshe ukwakheka, i-PVC iqinile. Xa ucinezela ivalvu yePVC enemisonto, ubeka amandla amakhulu ngaphandle eludongeni lwezixhobo zabasetyhini, uzama ukuyiqhekeza.ukuqinisa isandla kunye nokujika kube kanye ukuya kabini"Umthetho ngumgangatho wegolide ngesizathu esithile. Ukuqinisa isandla kukodwa kwenza imisonto idibane kakuhle. Ukujika okukodwa okanye okubini kokugqibela ngesikrufu kwanele ukucinezela amaleya eteyiphu yeTeflon, kudala isitywino esigqibeleleyo, esingangeni manzi ngaphandle kokubeka uxinzelelo oluyingozi kwiplastiki. Ndisoloko ndixelela amaqabane am ukuba "ukuqina" akulunganga xa usebenzisa iPVC. Ukulingana okuqinileyo, okuqinileyo kudala isitywino esihlala sihleli, esingavuziyo esiza kuhlala iminyaka emininzi.

Ungayiqhagamshela njani ivalvu yokuvala kwiPVC?

Kufuneka wongeze into yokuvala kumgca we-PVC okhoyo. Awuqinisekanga ukuba kufuneka usebenzise ivalvu enemisonto okanye ivalvu encamathiselweyo eqhelekileyo kule sicelo sithile.

Ukongeza ukuvala kumgca we-PVC okhoyo, ivalvu yebhola yomanyano lokwenyani yeyona ndlela ilungileyo. Ivumela ukugcinwa kwexesha elizayo. Sebenzisa uhlobo lwe-solvent-weld (socket) kwiinkqubo ze-PVC ezicocekileyo, okanye uhlobo olunemisonto ukuba luqhagamshela kufutshane nezixhobo zesinyithi.

Xa kufuneka unqumle umgca ukuze wongeze ukuvala, ukucinga ngekamva kubalulekile. Ivalvu yebhola yomanyano lokwenyani lolona khetho lubalaseleyo apha. Ungasika umbhobho, uncamathisele iziphelo ezimbini zomanyano, uze ufake umzimba wevalvu phakathi kwazo. Oku kungcono kakhulu kunevalvu eqhelekileyo kuba ungakhulula nje ii-union nuts ukuze ususe umzimba wonke wevalvu ukuze ucoce okanye utshintshe ngaphandle kokuphinda unqumle umbhobho. Ukuba inkqubo yakho yi-PVC eyi-100%, ivalvu yomanyano yokwenyani ye-solvent-weld (socket) igqibelele. Ukuba wongeza ukuvala ecaleni kwepompo okanye isihluzi ngemisonto yesinyithi, ngoko ke i-threaded.ivalvu yomanyano lokwenyaniyindlela efanelekileyo. Ungancamathisela iadaptha enemisonto kumbhobho wePVC kuqala, uze ufake ivalvu. Olu kuguquguquka yingakho thina kwaPntek sigxininisa kakhulu kuyilo lokwenyani lweyuniyoni.

Isiphelo

Ukufakela ngokufanelekileyo intambo exutyiweyoIvalvu yebhola yePVCSebenzisa iteyiphu yeTeflon, ungancamathiseli. Qinisa ngesandla kuqala, uze wongeze ujikelezo olunye okanye amabini ngesitshixo ukuze uvale kakuhle.
