Unevalvu nepayipi elifanele, kodwa iphutha elilodwa elincane ngesikhathi sokufakwa lingabangela ukuvuza okungapheli. Lokhu kukuphoqa ukuthi unqume konke bese uqala kabusha, uchithe isikhathi nemali.

Ukuze ufake i-ball valve epayipini le-PVC, kufanele uqale ukhethe uhlobo lokuxhuma olufanele: kungaba i-valve enentambo esebenzisa i-PTFE tape noma i-socket valve esebenzisa i-PVC primer kanye ne-samente. Ukulungiselela kanye nobuchwepheshe obufanele kubalulekile ukuze kuvikelwe kungavuzi.

Impumelelo yanoma yimuphi umsebenzi wokufaka amapayipi incike ekuxhumaneni. Ukuthola lokhu kahle kuyinto engixoxa ngayo njalo nabalingani abanjengoBudi e-Indonesia, ngoba amakhasimende akhe abhekana nalokhu nsuku zonke. I-valve evuzayo cishe ayikaze ibe ngenxa yokuthi i-valve ngokwayo imbi; kungenxa yokuthi i-joint ayenziwanga kahle. Izindaba ezinhle ukuthi ukudala uphawu oluphelele noluhlala njalo kulula uma ulandela nje izinyathelo ezimbalwa ezilula. Ukukhetha okubaluleke kakhulu ozokwenza ukunquma ukuthi uzosebenzisa imicu noma i-glue.

Ungayixhuma kanjani i-valve yebhola ku-PVC?

Ubona amavalvu anezintambo kanye namasokhethi atholakalayo. Ukukhetha okungalungile kusho ukuthi izingxenye zakho ngeke zilingane, okumisa iphrojekthi yakho uze uthole ivalvu efanele.

Uxhuma ivalvu yebhola ku-PVC ngenye yezindlela ezimbili. Usebenzisa ukuxhumeka okunezintambo (i-NPT noma i-BSP) kwezinhlelo ezingase zidingeke zihlukaniswe, noma ukuxhumeka kwe-socket (i-solvent weld) kwejoyinti elihlala njalo nelinamathelisiwe.

Isinyathelo sokuqala njalo ukufanisa ivalvu yakho nohlelo lwakho lwamapayipi. Uma amapayipi akho e-PVC esevele eneziphetho zentambo yesilisa, udinga ivalvu yesifazane enentambo. Kodwa emisebenzini eminingi emisha yokufaka amapayipi, ikakhulukazi yokunisela noma yokuchibi, uzosebenzisa amavalvu esokhethi kanye nesamente esinyibilikisayo. Ngikuthola kuwusizo njalo lapho ithimba likaBudi libonisa amakhasimende ithebula ukuze licacise ukukhetha. Indlela inqunywa yivalvu onayo. Awukwazi ukunamathisela ivalvu enontambo noma ukufaka intambo kuvalvu esokhethi. Indlela evame kakhulu nehlala njalo yokuxhumanisa i-PVC ne-PVC yi-isokhethinomaukushintshwa kwe-solvent, indlela. Le nqubo ayigcini nje ngokunamathelisa izingxenye ndawonye; ihlanganisa ngamakhemikhali ivalvu kanye nepayipi kube yingcezu eyodwa yepulasitiki engenamthungo, eqinile kakhulu futhi ethembekile uma yenziwe kahle.

Ukuhlukaniswa Kwendlela Yokuxhumana

Ingabe ikhona indlela efanele yokufaka i-ball valve?

Ucabanga ukuthi ivalvu isebenza ngendlela efanayo kunoma iyiphi indlela. Kodwa ukuyifaka ngendlela engafanele kungavimbela ukugeleza, kudale umsindo, noma kwenze kube nzima ukuyilungisa kamuva.

Yebo, ikhona indlela efanele. Ivalvu kufanele ifakwe ngesibambo esifinyeleleka kalula, ama-union nuts (kuvalvu yangempela ye-union) abekwe ukuze kube lula ukususa, futhi ahlale evulekile ngesikhathi sokunamathelisa.

Imininingwane emincane eminingana ihlukanisa ukufakwa kochwepheshe kokungena okungewona ama-amateur. Okokuqala,ukuqondisa isibamboNgaphambi kokuthi unamathisele noma yini, beka ivalvu bese uqinisekisa ukuthi isibambo sinendawo eyanele yokuguqula ama-degree angu-90 agcwele. Ngibone amavalvu efakwe eduze kodonga kangangokuthi isibambo singavuleka phakathi nendawo kuphela. Kuzwakala kulula, kodwa kuyiphutha elivamile. Okwesibili, kumavalvu ethu e-True Union, sifaka ama-union nuts amabili. Lawa aklanyelwe ukuze ukwazi ukuwavula bese uphakamisa umzimba wevalvu uphume epayipini ukuze isetshenziswe. Kufanele ufake ivalvu enesikhala esanele sokukhulula la ma-nuts. Isinyathelo esibaluleke kakhulu, nokho, isimo sevalvu ngesikhathi sokufakwa.

Isinyathelo Esibaluleke Kakhulu: Gcina Ivalvu Ivuliwe

Uma unamathisela i-valve yesokhethi nge-glue (ukushisela i-solvent), i-valvekumelekufanele kube sendaweni evulekile ngokuphelele. Izinyibilikisi eziku-primer kanye nesamente zenzelwe ukuncibilikisa i-PVC. Uma ivalvu ivaliwe, lezi zinyibilikisi zingabanjwa ngaphakathi komzimba wevalvu bese zinamathisela ibhola ngamakhemikhali emgodini wangaphakathi. Ivalvu izovalwa unomphela. Ngitshela uBudi ukuthi lena yimbangela yokuqala "yokwehluleka kwevalvu entsha." Akuyona inkinga yevalvu; yiphutha lokufakwa elingavinjelwa ngo-100%.

Unganamathisela kanjani i-valve yebhola le-PVC?

Ufaka inhlaka bese unamathisela izingxenye ndawonye, ​​kodwa ilunga liyahluleka uma licindezelwa. Lokhu kwenzeka ngoba “ukunamathela” empeleni kuyinqubo yamakhemikhali edinga izinyathelo ezithile.

Ukuze unamathelise kahle ivalvu yebhola le-PVC, kumele usebenzise indlela ye-primer enezinyathelo ezimbili kanye ne-samente. Lokhu kuhilela ukuhlanza, ukufaka i-primer ensomi kuzo zombili izindawo, bese usebenzisa i-samente ye-PVC ngaphambi kokuzihlanganisa ngokujika.

Le nqubo ibizwa ngokuthi ukushisela i-solvent, futhi idala isibopho esiqine kunepayipi uqobo. Ukweqa izinyathelo kuyisiqinisekiso sokuvuza kwesikhathi esizayo. Nansi inqubo esiqeqesha abasabalalisi beBudi ukuthi bayilandele:

1. Ukufaneleka Komile Kuqala.Qiniseka ukuthi ipayipi liphuma ngaphakathi kwesokhethi yevalvu.
2. Hlanza Izingxenye Zombili.Sebenzisa indwangu ehlanzekile neyomile ukuze usule noma yikuphi ukungcola noma umswakama ngaphandle kwepayipi kanye nangaphakathi kwesokhethi yevalvu.
3. Faka i-Primer.Sebenzisa i-dauber ukufaka i-liberal coat ye-PVC primer ngaphandle kwephayiphi kanye nangaphakathi kwe-socket. I-primer ihlanza ubuso ngamakhemikhali bese iqala ukuthambisa ipulasitiki. Lesi yisinyathelo esidlulelwe kakhulu nesibaluleke kakhulu.
4. Faka usimende.Ngesikhathi i-primer isemanzi, faka ungqimba olulinganayo lwesimende se-PVC ezindaweni ezi-primed. Ungasebenzisi kakhulu, kodwa qiniseka ukuthi imbozwe ngokuphelele.
5. Xhuma bese ujika.Faka ipayipi ngokushesha ebhodweni lize liphume phansi. Njengoba ucindezela, liphendule ngekota. Lokhu kunyakaza kusakaza usimende ngokulinganayo futhi kususe noma yimaphi amabhamuza omoya avalelekile.
6. Bamba bese Uphulukisa.Bamba ijoyinti liqine endaweni yalo cishe imizuzwana engama-30 ukuze uvimbele ipayipi ukuthi lingaphumi libuyele emuva. Ungalithinti noma uliphazamise ijoyinti okungenani imizuzu eyi-15, futhi ulivumele liphole ngokuphelele ngokwemiyalelo yomenzi wesimende ngaphambi kokucindezela uhlelo.

Uyenza kanjani i-PVC ball valve ibe lula ukuyijika?

Ivalvu yakho entsha sha iqinile kakhulu, futhi ukhathazekile ngokunqamula isibambo. Lokhu kuqina kungakwenza ucabange ukuthi ivalvu ayinasici kanti empeleni kuwuphawu lwekhwalithi.

Ivalvu entsha ye-PVC esezingeni eliphezulu iqinile ngoba izihlalo zayo ze-PTFE zakha uphawu oluqinile noluphelele ngokumelene nebhola. Ukuze ijike kalula, sebenzisa isikrufu esikweleni esisekelweni sesibambo ukuze uthole amandla angcono okuliphula.

Ngihlala ngithola lo mbuzo. Amakhasimende athola i-Pntek yethuamavalvufuthi bathi kunzima kakhulu ukuzijika. Lokhu kwenziwa ngenhloso. Amasongo amhlophe ngaphakathi, izihlalo ze-PTFE, abunjwe ngokunemba ukuze adale uphawu oluqinile njengebhamuza. Lokho kuqina yikho okuvimbela ukuvuza. Amavalvu ashibhile anezimpawu ezikhululekile aphenduka kalula, kodwa futhi ayahluleka ngokushesha. Cabanga ngakho njengezicathulo zesikhumba ezintsha; zidinga ukuphulwa. Indlela engcono kakhulu yokwenza lokhu ukusebenzisa i-wrench encane elungisekayo engxenyeni ebanzi, eyisikwele yeshaft yesibambo, khona kanye esisekelweni. Lokhu kukunika amandla amaningi ngaphandle kokufaka ingcindezi esibambeni se-T uqobo. Ngemva kokusivula nokusivala izikhathi ezimbalwa, sizoba bushelelezi kakhulu.Ungalokothi usebenzise i-WD-40 noma ezinye izinto zokugcoba ezisekelwe kumafutha.Le mikhiqizo ingahlasela futhi yenze buthaka ipulasitiki ye-PVC kanye nezivalo ze-EPDM O-ring, okubangela ukuthi ivalvu yehluleke ngokuhamba kwesikhathi.

Isiphetho

Ukufakwa okufanele, kusetshenziswa indlela efanele yokuxhuma, ukuqondisa, kanye nenqubo yokunamathisela, kuyindlela kuphela yokuqinisekisaI-valve yebhola ye-PVCinikeza impilo yesevisi ende, ethembekile, engenawo amanzi.
