Ubona ukuvuza okungaguqukiyo kwivalvu yebhola yePVC. Oku kuvuza kuncinci kunokukhokelela kumonakalo omkhulu wamanzi, okubangela ukuba inkqubo ivalwe kwaye kufuneke umnxeba ongxamisekileyo kumcebisi wemibhobho.
Ungayilungisa ivalvu yebhola yePVC evuzayo ukuba yidizayini yokwenyani yeyuniyoni. Ukulungiswa kuquka ukuchonga umthombo wokuvuza—ngokuqhelekileyo isiqu okanye iinuts zeyuniyoni—uze uqinise uqhagamshelo okanye ufake ezinye izitywina zangaphakathi (ii-O-rings).
Le yingxaki eqhelekileyo abathengi baseBudi eIndonesia abajongene nayo.ivalvu evuzayokwindawo yokwakha okanye ekhayeni kunokuthintela umsebenzi kwaye kubangele ukukhungatheka. Kodwa isisombululo sidla ngokuba lula kakhulu kunokuba becinga, ingakumbi xa besebenzisa izinto ezifanelekileyo kwasekuqaleni. Ivalvu eyilwe kakuhle yivalvu elungisekayo. Masihambe ngamanyathelo okulungisa oku kuvuza kwaye, okubaluleke ngakumbi, indlela yokukuthintela.
Ngaba ivalvu yebhola evuzayo ingalungiswa?
Ivalvu iyavuza, kwaye ingcinga yakho yokuqala kukuba kufuneka uyinqumle. Oku kuthetha ukukhupha amanzi kwinkqubo, ukusika umbhobho, kunye nokutshintsha yonke iyunithi ukuze uthontsize nje.
Ewe, ivalvu yebhola ingalungiswa, kodwa kuphela ukuba yivalvu yokwenyani yomanyano (okanye ivalvu yomanyano oluphindwe kabini). Uyilo lwayo oluneziqwenga ezintathu lukuvumela ukuba ususe umzimba kwaye ufake ezinye izitywini zangaphakathi ngaphandle kokuphazamisa imibhobho.
Ukukwazi ukulungisa ivalvu sesona sizathu sikhulu sokuba iingcali zikhethe uyilo lokwenyani lwe-union. Ukuba unevalvu yebhola "encinci" enye evuzayo, ukhetho lwakho kuphela kukuyisika uze uyitshintshe. Kodwa iivalvu yomanyano lokwenyanievela kwi-Pntek yenzelwe ubomi obude benkonzo.
Ukuchonga uMthombo Wokuvuza
Ukuvuza kwamanzi phantse rhoqo kuvela kwiindawo ezintathu. Nantsi indlela yokukubona nokukulungisa:
| Indawo yokuvuza | Unobangela oQhelekileyo | Indlela Yokulungisa |
|---|---|---|
| Ejikeleze iHandle/Isiqu | I-nut yokupakisha ikhululekile, okanye isiquIindandatho ze-Ozinxitywe. | Okokuqala, zama ukuqinisa i-packing nut ngaphantsi nje kwesibambo. Ukuba isavuza, tshintsha ii-stem O-rings. |
| Kwi-Union Nuts | I-nut ikhululekile, okanye i-O-ring ethwalayo yonakele okanye ingcolile. | Khulula i-nut, coca i-O-ring enkulu kunye nemisonto, ujonge ukuba ayonakali na, uze uyiqinise kwakhona ngesandla. |
| Ukuqhekeka kwiValve Body | Ukuqiniswa kakhulu, ukubanda, okanye ukuchatshazelwa ngokomzimba kuye kwaqhekeka i-PVC. | Iumzimba wevalvukufuneka itshintshwe. Ngevalvu yomanyano yokwenyani, ungathenga umzimba omtsha, kungekhona yonke ikhithi. |
Ungayilungisa njani ipayipi yePVC evuzayo ngaphandle kokuyitshintsha?
Ufumana ithontsi elincinci kumbhobho othe tye, kude nokulingana. Ukutshintsha indawo eneenyawo ezili-10 ukuze kubekho ukuvuza okuncinci kwemingxuma kuvakala ngathi kukuchitha ixesha elininzi kunye nezinto zokwakha.
Ukuba kukho ukuvuza okuncinci okanye umngxuma omncinci, ungasebenzisa isixhobo sokulungisa irabha kunye ne-clamp ukulungisa ngokukhawuleza. Ukuze ufumane isisombululo esihlala sihleli kwi-crack, ungasika indawo eyonakeleyo uze ufake i-slip coupling.
Nangona sigxile kwiivalvu, siyazi ukuba ziyinxalenye yenkqubo enkulu. Abathengi bakaBudi bafuna izisombululo ezisebenzayo kuzo zonke iingxaki zabo zombhobho. Ukulungisa umbhobho ngaphandle kokutshintshwa ngokupheleleyo sisakhono esibalulekileyo.
Ukulungiswa kwexeshana
Kwindawo evuzayo encinci kakhulu, i-patch yexeshana ingasebenza de kubekho ukulungiswa okusisigxina. Ungasebenzisa i-specializedI-epoxy yokulungisa i-PVCokanye indlela elula ebandakanya isiqwenga se-gasket yerabha ebanjwe ngokuqinileyo phezu komngxuma nge-hose clamp. Oku kulungile xa kukho imeko engxamisekileyo kodwa akufuneki kuthathwe njengesisombululo sokugqibela, ingakumbi xa kucinezelwe.
Ulungiso olusisigxina
Indlela yobungcali yokulungisa icandelo elonakeleyo lombhobho kukusebenzisa i-“slip” coupling. Olu fakelo alunawo umqobo wangaphakathi, nto leyo evumela ukuba lutyibilike ngokupheleleyo phezu kombhobho.
- Sika iqhekeza lombhobho eliqhekekileyo okanye elivuzayo.
- Coca kwaye ucofe iziphelo zombhobho okhoyo kunye nangaphakathi kwawoukudibanisa okutyibilikayo.
- Faka isamente yePVC uze uslayide i-coupling yonke kwicala elinye lombhobho.
- Lungelelanisa imibhobho ngokukhawuleza uze uslayide i-coupling umva phezu kwesithuba ukuze ugqume amacala omabini. Oku kudala i-joint ehlala ihleli, ikhuselekile.
Ungayincamathisela njani ivalvu yebhola yePVC?
Ufake ivalvu, kodwa uqhagamshelo ngokwalo luyavuza. I-glue joint engafanelekanga ayihlali ihleli, nto leyo ekunyanzela ukuba usike yonke into kwaye uqale phantsi.
Ukuze uncamathisele ivalvu yebhola yePVC, kufuneka usebenzise inkqubo enamanyathelo amathathu: coca kwaye ucofe zombini umbhobho kunye nesokhethi yevalvu, ufake isamente yePVC ngokulinganayo, uze ufake umbhobho nge-quarter-turn twist ukuqinisekisa ukugquma ngokupheleleyo.
Uninzi lokuvuza aluveli kwivalvu ngokwayo, kodwa luvela kuqhagamshelo olubi.ukuwelda kwesinyibilikisiKubalulekile. Ndisoloko ndimkhumbuza uBudi ukuba abelane ngale nkqubo nabathengi bakhe kuba ukuyenza ngokuchanekileyo okokuqala kuthintela phantse zonke iingozi ezinxulumene nokufakelwa.
Amanyathelo Amane Okuya Kwi-Weld Egqibeleleyo
- Sika kwaye Ususe Izinto Ezingafunekiyo:Umbhobho wakho kufuneka usikwe ube sisikwere ngokugqibeleleyo. Sebenzisa isixhobo sokususa iimbumbulu ukuze ususe naziphi na iimbumbulu zeplastiki ezirhabaxa ngaphakathi nangaphandle kwesiphelo sombhobho. Iimbumbulu zinokubanjwa kwivalvu zize zibangele ukuvuza kamva.
- Ucoceko kunye nePrime:Sebenzisa isicoci sePVC ukususa ukungcola kunye negrisi kwisiphelo sombhobho kunye nangaphakathi kwesokhethi yevalvu. Emva koko, yifakeIprimer yePVCI-primer ithambisa iplastiki, nto leyo efunekayo kwi-weld enamandla yeekhemikhali.
- Faka iSamente:Faka isamente yePVC ethambileyo nelinganayo ngaphandle kombhobho uze ufake isamente encinci ngaphakathi kwesokhethi yevalvu. Musa ukulinda ixesha elide emva kokufaka iprimer.
- Faka kwaye Ujije:Tyhala umbhobho ngokuqinileyo ungene kwisokethi ude uphume ezantsi. Njengoko utyhala, yijike ngekota. Esi senzo sisasaza isamente ngokulinganayo kwaye sincede ekususeni nawuphi na umoya ovalelekileyo. Yibambe ngokuqinileyo endaweni yayo ubuncinane imizuzwana engama-30, njengoko umbhobho uza kuzama ukutyhala umva.
Ngaba iivalvu zebhola zePVC ziyavuza?
Umthengi ukhalaza ngelithi ivalvu yakho inesiphene kuba iyavuza. Oku kungonakalisa igama lakho, nokuba ingxaki ayikho kwimveliso ngokwayo.
Iivalvu zebhola zePVC ezikumgangatho ophezulu azivuzi rhoqo ngenxa yeziphene zokwenziwa. Ukuvuza kusoloko kubangelwa kukufakelwa okungafanelekanga, ukungcola okungcolisa izitywini, umonakalo emzimbeni, okanye ukuguga kwendalo kunye nokuguguleka kwee-O-rings ngokuhamba kwexesha.
Ukuqonda isizathu sokuba iivalvu zingasebenzi kakuhle kubalulekile ekunikezeni inkonzo egqwesileyo. KwaPntek, imveliso yethu ezenzekelayo kunye nolawulo oluqinileyo lomgangatho kuthetha ukuba iziphene aziqhelekanga kakhulu. Ngoko ke xa kuxelwa ukuvuza, unobangela uhlala ungaphandle.
Izizathu Eziqhelekileyo Zokuvuza KweeNkobe
- Iimpazamo zoFakelo:Le yeyona nto iphambili. Njengoko besixoxile, i-solvent weld engafanelekanga iya kuhlala ingaphumeleli. Ii-union nuts eziqina kakhulu zingonakalisa ii-O-rings okanye ziqhekeze umzimba wevalvu.
- Inkunkuma:Amatye amancinci, isanti, okanye iipayiphu ezifakwe ngendlela engafanelekanga zinokungena phakathi kwebhola kunye nesitywini. Oku kudala umsantsa omncinci ovumela amanzi ukuba adlule nokuba ivalvu ivaliwe.
- Nxibela ukuyikrazula:Ii-O-rings zenziwe ngerabha okanye izinto ezifanayo. Kwisithuba samawaka eminyaka yokujika kunye neminyaka yokuchatshazelwa ziikhemikhali zamanzi, zinokuba nzima, ziqhekeke, okanye zicinezelwe. Ekugqibeleni, ziya kuyeka ukutywina ngokugqibeleleyo. Oku kuqhelekile kwaye yingakho ukulungiseka kubaluleke kangaka.
- Umonakalo Womzimba:Ukuwisa ivalvu, ukuyibetha ngezixhobo, okanye ukuyivumela ukuba iqine ngamanzi ngaphakathi kunokubangela imingxunya yeenwele eza kuvuza xa ixinzelelekile.
Isiphelo
UkuvuzaIvalvu yebhola yePVCingalungiswa ukubauyilo lomanyano lokwenyaniKodwa ukuthintela kungcono. Ukufakela ngokufanelekileyo ngundoqo kwinkqubo engenamanzi kwiminyaka ezayo.
