Ufake ivalvu entsha, ulindele ukuvalwa okuphelele. Ukuconsa kancane, okuthule kungadala umonakalo wamanzi njengamanje, ngaphandle kokwazi kwakho futhi konakalise umsebenzi wakho onzima.

Ivalvu yebhola ye-PVC esezingeni eliphezulu akufanele ivuze. Ukuvuza cishe njalo kwenzeka ngenxa yokufakwa okungafanele, umonakalo ongokwenyama, noma ubudala obukhulu, hhayi ngenxa yephutha lokukhiqiza kuvalvu eyenziwe kahle.

Leli iphuzu elibalulekile lokwethembana phakathi komkhiqizi nochwepheshe. Uma ngixoxa ngekhwalithi yomkhiqizo wethu nabalingani abanjengoBudi e-Indonesia, lesi yisihloko esisixoxa ngokuningiliziwe. Amakhasimende akhe, osonkontileka nabakhi, bathembele ezingxenyeni abazifakile ukuze zingabi naphutha. Ukuvuza okukodwa kungalimaza idumela labo. Ngakho-ke, kubalulekile ukuqonda ukuthi ivalvu ngokwayo yenzelwe ukubaingavuziUkugxila kwangempela kudingeka kube yizimbangela ezivamile zokuvuza okwenzeka ensimini, cishe ezingavinjelwa ngaso sonke isikhathi.

Ingabe ama-valve ebhola le-PVC angavuza?

Unamathisele i-valve ye-PVC futhi umsebenzi usuphelile. Kodwa iphutha elincane ejoyintini lingabangela ukuvuza kamuva, okuphoqa ukuthi kwenziwe kabusha okukhungathekisayo nokubizayo.

Yebo, zingavuza. Izindawo ezivame kakhulu ukuvuza akuzona izivalo zangaphakathi zevalvu kodwa ukuxhumana kwangaphandle—kungaba amalunga e-solvent anganamatheli kahle noma ukuxhumana okunezintambo okungavalwanga kahle, hhayi umzimba wevalvu uqobo.

Ngisho nevalvu engcono kakhulu emhlabeni izovuza uma ingafakwanga kahle. Ukuqonda ukuthi ukuvuza kwenzeka kuphi kuyisinyathelo sokuqala sokukuvimbela. Ngokwami, kunezindawo ezintathu eziyinhloko lapho ukuvuza kungavela khona.

1. Ukuvuza Kwama-Connections(Okuvamile Kakhulu)

Yilapho ukuvuza okungaphezu kuka-90% kwenzeka khona.

• Amajoyinti Ahlanganisiwe Nge-Solvent:Ukuvuza lapha kusho ukuthi ukushintshwa kwamakhemikhali bekungaphelele. Lokhu kungenzeka uma kungasetshenziswanga usimende owanele, ipayipi lingafakwanga ngokuphelele kusokhethi yevalvu, noma ukujikwa okubalulekile kwekota-turn kungenziwanga ukuze kusabalaliswe usimende ngokulinganayo.
• Ukuxhumeka Okunemicu:Ukuvuza ezinhlanganisweni ezinezintambo kuvame ukubangelwa ukungasebenzisi i-PTFE thread seal tape eyanele noma ukuyisebenzisa kabi. Ukuqinisa kakhulu kungenye imbangela enkulu; kungadala ukuqhekeka okuncane ekufakweni kwabesifazane, okuholela ekuconseni kancane.

2. Ukuvuza Okuvela Esiqwini Sesibambo

Lokhu akuvamile, ikakhulukazi kuma-valve amasha. Ngaphakathi kwe-valve, isiqu esixhuma esibambweni sivalwe nge-EPDM O-rings eyodwa noma ngaphezulu. Uma kuvela ukuvuza ngaphansi kwesibambo, kusho ukuthi lesi sivalo siphazamisekile. Ku-valve yomanyano yangempela, ngezinye izikhathi ungaqinisa i-packing nut ukuze ucindezele lesi sivalo futhi umise ukuvuza. Ku-valve encane, lokhu kuvame ukudinga ukushintshwa.

3. Ukuvuza Nge-Valve (Ngaphakathi)

Lolu uhlobo olungavamile lokuvuza ku-valve esezingeni eliphezulu. Lokhu kusho ukuthi i-valve iyavuza uma isendaweni evaliwe. Lokhu kuvame ukwenzeka ngoba imfucumfucu efana nedwala elincane noma isihlabathi ibanjwa ngaphakathi, okuvimbela ibhola ukuthi livale ngokuphelele esihlalweni se-PTFE.

Ama-valve ebhola e-PVC athembeke kangakanani?

Udinga ivalvu ongayifaka futhi uyethembe iminyaka eminingi. Ukukhetha ivalvu eshibhile, engakaqinisekiswa kungaholela ekubuyiselweni emuva, kulimaze idumela lakho kanye nenzuzo emsebenzini.

Amavalvu ebhola e-PVC asezingeni eliphezulu athembeke kakhulu ngenxa yokwakheka kwawo okulula anezingxenye ezimbalwa ezihambayo. Ukuthembeka kwawo kuncike ngokuphelele kwikhwalithi yezinto zokwakha kanye nokukhiqizwa okunembile okusetshenziselwa ukuzenza.

Ukukhanya okulula kwe-ivalvu yebholayikho okwenza ithembeke kangaka. Umklamo uqinile ngokomshini: ibhola elinembobo lijikeleza ama-degree angu-90 liye endaweni evulekile noma evaliwe. Zimbalwa kakhulu izinto ezingahamba kabi. Kodwa-ke, akuwona wonke ama-valve ebhola e-PVC adalwe alingana. Umehluko phakathi kwe-valve ethembekile nengathembekile uncike ekhwalithini yezinto zokusetshenziswa kanye nenqubo yokukhiqiza. Lokhu kuyinto thina kwa-Pntek esiyithatha ngokungathi sína kakhulu. I-valve eshibhile ingase ibukeke ifana ngaphandle, kodwa yilokho okungaphakathi okubalulekile.

Ingxenye	I-Pntek Valve Esezingeni Eliphezulu	I-Valve Ejwayelekile Esezingeni Eliphansi	Umthelela Ekuthembekeni
Umzimba weValve	I-PVC engu-100% eyi-Virgin	I-PVC ephinde yasetshenziswa enezigcwalisi (i-calcium)	I-Virgin PVC iqinile futhi ayishayisani. Izinto eziphinde zasetshenziswa zingaphuka futhi ziqhekeke ngaphansi kwengcindezi noma ngesikhathi sokufakwa.
Ibhola	Kwenziwe ngomshini oqondile, obushelelezi	Ubuso obuqinile, usayizi ongaguquki	Ibhola elibushelelezi lidala uphawu oluhle futhi liphenduka kalula. Ibhola elinolaka lizoguga izihlalo futhi libangele ukuvuza.
Izihlalo	I-PTFE eyi-Virgin engu-100%	Ipulasitiki eshibhile	I-PTFE (Teflon) inikeza isivalo esingashayisani kahle, esihlala isikhathi eside, futhi esingamelani namakhemikhali. Izinto ezishibhile zinganamathela noma zonakale ngokushesha.
Ama-O-Rings	I-EPDM noma i-FKM (i-Viton)	Irabha eyisisekelo (i-NBR)	I-EPDM inikeza ukumelana okuhle kakhulu nokushisa namakhemikhali ezinhlelweni zamanzi. Irabha eyisisekelo ingavuvukala noma ibole ngokuhamba kwesikhathi.

I-valve ethembekile iwukutshala imali ekuthuleni kwengqondo.

I-valve yebhola ye-PVC izohlala isikhathi esingakanani?

Udinga ukwazi isikhathi sokuphila kwezingxenye ozifakile. Kodwa ama-valve awanayo idethi yokuphelelwa yisikhathi ecacile, okwenza ukuhlela isikhathi eside kube nzima futhi kudale ukungaqiniseki kumakhasimende ngezinkinga zesikhathi esizayo.

Ivalvu yebhola ye-PVC eyenziwe kahle, esetshenziswa ezimweni ezifanele, ingahlala iminyaka eyi-10 kuya kwengama-25 noma ngaphezulu. Isikhathi sokuphila sithinteka kakhulu yimisebe ye-UV, izinga lokushisa, ukuchayeka kumakhemikhali, nokuthi isetshenziswa kangaki.

Akukho usuku oluqondile lokuphelelwa yisikhathi kwevalvu ye-PVC ngoba isikhathi sayo sokuphila sincike kakhulu endaweni ezungezile kanye nendlela esetshenziswa ngayo. Ivalvu efakwe ngaphakathi entanjeni yamanzi abandayo esetshenziswa izikhathi ezimbalwa ngonyaka ingase ihlale amashumi eminyaka. Ivalvu efakwe ngaphandle entanjeni yamanzi ashisayo esebenza nsuku zonke izoba nesikhathi esifushane kakhulu. Ukuqonda izici ezifinyeza impilo yevalvu kubalulekile ekukhuliseni isikhathi sayo.

• Ukuvezwa kwe-UV:Lesi yisitha esikhulu se-PVC.Ukukhanya kwelanga okuqondile kwenza i-PVC ibe buthaka ngokuhamba kwesikhathiNoma yiliphi ivalvu elifakwe ngaphandle kufanele livikelwe elangeni, kungaba ngokulisonga noma ngokulipenda ngopende we-latex osekelwe emanzini.
• Izinga Lokushisa Eliphezulu: I-PVC iba thambile njengoba ishisa kakhulu, okunciphisa izinga layo lokucindezela. Ivalvu ehlala ivulekele emanzini ashisayo (eduze komkhawulo wayo omkhulu ongu-140°F / 60°C) ingaphansi kokucindezeleka okukhulu futhi izoguga ngokushesha.
• Amakhemikhali:Nakuba i-PVC imelana namakhemikhali amaningi, izinto ezinamandla zingahlasela ipulasitiki noma i-Izimpawu ze-EPDM/FKMHlola njaloukuhambisana kwamakhemikhaliishadi ukuthi ivalvu izosetshenziselwa yini enye into ngaphandle kwamanzi.
• Imvamisa Yokusetshenziswa:Ivalvu iyithuluzi elisebenza ngomshini. Uma iphendulwa kakhulu, izihlalo nezivalo zizoguga kakhulu. Ukuze kusetshenziswe ngebhayisikili ephezulu, kubalulekile ukukhetha ivalvu eyenzelwe leyo njongo.

Ungayivimba kanjani ivalvu yebhola ukuthi ingavuzi?

Ubone ukuvuza okwesabekayo okuvela ekuxhumekeni kwevalvu. Umcabango wakho wokuqala ukulungisa okunzima, ukusika ipayipi nokuchitha amahora amaningi esikhathi sakho nomzamo wakho.

Uma kuvuza esibambweni, zama ukuqinisa ama-union nuts noma i-packing nut. Uma kuvuza ngentambo, kufanele uvale kabusha izintambo. Uma kuvuza esibambweni esinamathelisiwe, i-valve kumele inqunywe bese ishintshwa.

Ukulungisa ukuvuza kuncike ngokuphelele ekutheni amanzi avelaphi. Isinyathelo sokuqala ukuvala amanzi bese ukhulula noma yikuphi ukucindezela emgqeni.

Ukulungisa Ukuvuza Okuvela Esiqwini Sesibambo

Lokhu kuvuza kuvela njengokuvuza lapho isibambo singena khona emzimbeni wevalvu. Ku-Pntek yethuama-valve e-union yangempela, lokhu kuvame ukulungiswa. Ungakhulula ama-union nuts amakhulu kuzo zombili izinhlangothi zomzimba we-valve. Lokhu kukuvumela ukuthi uphakamise umongo we-valve uphume epayipini. Kulo mongo, kukhona i-nut enkulu ezungeze isiqu. Ukuqinisa kancane le nut (ebizwa ngokuthi i-carrier noma i-packing nut) kungacindezela ama-O-rings futhi kumise ukuvuza. Kuma-valve amancane, ayisiqephu esisodwa, lokhu akunakwenzeka futhi i-valve kumele ishintshwe.

Ukulungisa Ukuvuza Okuvela Kuxhumano Olunezintambo

Lokhu kuvuza okungalungiseka kodwa okucasulayo. Kumelwe ukhiphe intambo ngokuphelele ku-valve ekufakweni. Hlanza kahle yonke i-tape endala yokuvala intambo noma unamathisele kuzo zombili izintambo zesilisa nezesifazane. Bese, phinda ufake okusha, kwekhwalithi ephezuluItheyiphu ye-PTFE(3-4 wraps bebheke ohlangothini lwezintambo). Hlanganisa kabusha ijoyinti, uliqinise ngokuqinile kodwa uqaphele ukuthi ungaliqinisi kakhulu futhi ungaliqhekezi i-fitting.

Ukulungisa Ukuvuza Okuvela Ku-Solvent Weld (Okunamathelisiwe) Joint

Lokhu ukuvuza okukodwa ongeke ukulungise. Akukho mkhiqizo noma indlela engalungisa ngokuthembekile ukuvuzaijoyinti elihlanganisiwe nge-solventIsixazululo sobungcweti nesihlala njalo kuphela ukusika ivalvu epayipini bese ufaka elisha. Yingakho kubaluleke kakhulu ukwenza inqubo yokunamathisela ibe yinhle okokuqala.

Isiphetho

IkhwalithiI-valve ye-PVCakufanele kuvuze. Ukuvuza cishe njalo kuvela emaphutheni okufakwa, hhayi ivalvu uqobo. Ukwazi imbangela kuyisihluthulelo sokulungisa okusheshayo nokuhlala njalo.
