Ufake ngononophelo ivalve entsha yePVC enemisonto, kodwa ithontsiza kancinane ukusuka kwimisonto. Ukuyiqinisa ngakumbi kuvakala kusemngciphekweni, njengoko usazi ukuba ujiko olunye oluninzi lunokwaphula ukufaneleka.

Ukufakela ngempumelelo i-valve yebhola ye-PVC ene-threaded, gubungela iintambo zamadoda kunye ne-3-4 ye-tape ye-Teflon. Songa rhoqo kwicala lokuqinisa. Emva koko, yijije ngesandla, kwaye usebenzise isitshixo sojiko olunye okanye ezimbini zokugqibela.

Umsonto ovuzayo yenye yezona zinto zixhaphakileyo kwaye zinxunguphalisa ukusilela kokufaka. Phantse isoloko ibangelwa yimpazamo encinci, ephephekayo ekulungiseleleni okanye ekuqiniseni. Ndihlala ndixoxa ngale nto kunye neqabane lam e-Indonesia, eBudi, kuba yintloko ebuhlungu rhoqo abathengi bakhe abajongene nayo. Uqhagamshelo olukhuselekileyo, olungavuziyo olungavuziyo kulula ukulufikelela. Kufuneka ulandele amanyathelo ambalwa alula, kodwa abaluleke kakhulu. Masiphendule imibuzo ephambili ukuyilungisa ngalo lonke ixesha.

Ufakela njani umsonto wePVC ofakelweyo?

Usebenzise intlama yokutywina esebenza kakuhle kwintsimbi, kodwa ukufakwa kwakho kwePVC kusavuza. Okubi kakhulu, unexhala lokuba iikhemikhali ezikuncama zingonakalisa iplastiki ekuhambeni kwexesha.

Kwimisonto yePVC, soloko usebenzisa iteyiphu yeTeflon endaweni yedope yombhobho okanye uncamathisele. Gquba imisonto yamadoda ngamaxesha angama-3-4 kwicala elifanayo uya kuqinisa ukulungelelaniswa, uqinisekise ukuba i-tape ibeka i-flat kwaye ilula ukudala itywina eligqibeleleyo.

Lo mahluko phakathi kweteyiphu kunye nokuncamathelisa ubalulekile kwizixhobo zeplastiki. Uninzi oluqhelekileyoimibhobho dopesziqulethe i-petroleum-based compounds ezinokuthi zihlasele i-PVC ngokwemichiza, iyenze ibe brittle kwaye inokuthi iqhekeke phantsi koxinzelelo oluqhelekileyo lokusebenza.Iteyiphu yeTeflon, kwelinye icala, i-inert ngokupheleleyo. Isebenza njenge-sealant kunye ne-lubricant, igcwalisa izithuba ezincinci kwimisonto ngaphandle kokudala uxinzelelo oluyingozi lwangaphandle olunokuthi unamathisele. Oku kuthintela uxinzelelo kwimfanelo yowesifazane.

Ukukhetha iSealant yePVC Imisonto

Xa usongela iintambo, soloko uhamba ngendlela ye-clockwise njengoko ujonge ekupheleni kokulinganisa. Oku kuqinisekisa ukuba njengoko uqinisa i-valve, i-tape igudiswa phantsi kunokuba ihlanganiswe kwaye ikhutshwe.

Indlela yokufaka ivalve yebhola kwipayipi yePVC?

Unevalve yebhola ephothiweyo kodwa umbhobho wakho ugudile. Kufuneka uzidibanise, kodwa uyazi ukuba awukwazi ukuncamathelisa imisonto okanye uthunge umbhobho ogudileyo. Yiyiphi imilinganiselo efanelekileyo?

Ukudibanisa ivalve yebhola ephothiweyo kumbhobho ogudileyo wePVC, kufuneka kuqala i-solvent-weld (iglu) iadaptha ephothiweyo eyindoda yePVC kumbhobho. Emva kokuba isamente iphiliswe ngokupheleleyo, ungafaka ivalve enemisonto kwiadaptha.

Awunakuze wenze imisonto kumbhobho wePVC oqhelekileyo, ogudileyo; udonga lubhityile kakhulu kwaye luya kusilela ngoko nangoko. Uqhagamshelo kufuneka lwenziwe ngeadaptha efanelekileyo. Kulo msebenzi, kufuneka aIadaptha yoBudoda yePVC(ehlala ibizwa ngokuba yi-MPT okanye iadaptha ye-MIPT). Elinye icala linesokethi egudileyo, kanti elinye linemisonto yamadoda. Usebenzisa i-primer ye-PVC esemgangathweni kunye nenkqubo yesamente ukuze udibanise isiphelo sesokethi kumbhobho wakho, udala iqhekeza elinye, elidibeneyo. Undoqo apha ngumonde. Kufuneka uyivumele loo ntounyango lwe-solvent-weldngokupheleleyo phambi kokufaka nayiphi na itorque kwimisonto. Ukusebenzisa amandla kwangethuba kakhulu kunokwaphula iqhina elitsha lekhemikhali, lidale ukuvuza kwindawo encamatheleyo. Ndihlala ndicebisa abathengi bakaBudi ukuba balinde ubuncinane iiyure ezingama-24 ukuze bakhuseleke.

Indlela yokufaka ivalve enemisonto?

Uyiqinise ivalve yakho entsha enomsonto yade yavakala ukuba iqinile, weva nje intanda egulisayo. Ngoku i-valve yonakalisiwe, kwaye kufuneka uyinqumle kwaye uqale konke.

Indlela echanekileyo yokuqinisa "yisandla esidibanisa nesinye ukuya kwezimbini." Yijike ngokulula ivalve ngesandla ide ithothe, emva koko sebenzisa isikrufu ukuyinika ithuba elinye okanye ezimbini zokugqibela. Yima apho.

Ukuqiniswa kakhulu ngunobangela wokuqala wokungaphumeleli kwimisonto yeplastiki efakelweyo. Ngokungafaniyo nentsimbi, enokwelula kunye nokukhubazeka, i-PVC iqinile. Xa ukrazula kwivalve yePVC enemisonto, ubeka amandla amakhulu angaphandle kwiindonga zomfazi, uzama ukuyicanda ivuleke. I-“qinisa ngesandla udibanise isinye ukuya kwezimbini"Umgaqo ngumgangatho wegolide ngenxa yesizathu. Ukuqinisa isandla kuphela kwenza ukuba imicu ibandakanyeke ngokufanelekileyo. Ukujika kokugqibela okanye ezimbini kunye ne-wrench kwanele nje ukucinezela iileya zeTeflon tape, ukudala itywina eligqibeleleyo, elingenamanzi ngaphandle kokubeka uxinzelelo oluyingozi kwiplastiki. iminyaka.

Indlela yokudibanisa ivalve yokuvala kwi-PVC?

Kufuneka udibanise ukuvala kumgca wePVC okhoyo. Awuqinisekanga ukuba kufuneka usebenzise ivalve enemisonto okanye ivalve eqhelekileyo encamatheleyo kwesi sicelo sikhethekileyo.

Ukongeza ukuvala kumgca wePVC okhoyo, ivalve yebhola yomanyano lolona khetho lungcono. Ivumela ukugcinwa kwexesha elizayo. Sebenzisa i-solvent-weld (socket) uguqulelo kwiinkqubo zePVC ezisulungekileyo, okanye uguqulelo oludityanisiweyo ukuba ludityaniswa kufutshane nezixhobo zentsimbi.

Xa ufuna ukusika kumgca ukongeza ukuvala, ukucinga ngekamva kubalulekile. Ivalve yebhola yomanyano lolona khetho luphezulu apha. Ungawusika umbhobho, uncamathelise iziphelo ezimbini zomanyano, uze ufakele umzimba wevalvu phakathi kwawo. Oku kungcono kakhulu kunevalve eqhelekileyo kuba unokukhulula nje amandongomane omanyano ukuze ususe wonke umzimba wevalvu ukuze ucoceke okanye utshintshe ngaphandle kokuphinda usikwe umbhobho kwakhona. Ukuba inkqubo yakho yi-100% yePVC, ivalve ye-solvent-weld (isokethi) yenyani yomanyano igqibelele. Ukuba ukongeza ukuvala ecaleni kwempompo okanye isihluzi esinemisonto yesinyithi, ngoko ke i-threadedivelufa yomanyano lwenyaniyindlela yokuhamba. Uya kuncamathelisa iadaptha enentambo kumbhobho wePVC kuqala, emva koko ufake ivalve. Oku bhetyebhetye kungoko thina ePntek sigxininisa uyilo lomanyano lokwenyani.

Ukuqukumbela

Ukufakela kakuhle intamboIvalve yebhola yePVC, sebenzisa iteyiphu yeTeflon, ungancamathiseli. Qinisa ngesandla kuqala, emva koko yongeza enye okanye ezimbini ukujika ngaphezulu ngesitshixo setywina eligqibeleleyo.
