Ususikiwe, kodwa uphawu oluvuzayo lusho ukuchitha isikhathi, imali, nezinto zokwakha. Ijoyinti elilodwa elibi emugqeni we-PVC lingaphoqa ukuthi usike sonke isigaba bese uqala kabusha.

Ukufaka i-valve yebhola kwipayipi ye-PVC, usebenzisa i-solvent welding. Lokhu kuhilela ukusika ipayipi ngokuhlanzekile, ukususa, ukusebenzisa i-PVC primer nosimende kuzo zombili izindawo, bese uziphusha ndawonye nge-quarter twist futhi ubambe ngokuqinile kuze kube yilapho ibhondi yamakhemikhali isetha.

Lokhu akukhona nje ukunamathelisa; kuyinqubo yamakhemikhali ehlanganisa ipulasitiki ibe ucezu olulodwa, oluqinile. Ukuyilungisa akuxoxiswana ngayo kochwepheshe. Kuyiphuzu engihlala ngigcizelela ngalo nozakwethu abafana no-Budi e-Indonesia. Amakhasimende akhe, kungakhathaliseki ukuthi osonkontileka abakhulu noma abathengisi bendawo, ancike ekuthembekeni. Ilunga elihlulekile alikona nje ukuvuza; ukubambezeleka kwephrojekthi futhi kuphazamisa isithunzi sabo. Ake siphendule imibuzo ebalulekile ukuze senze konke ukufakwa kube yimpumelelo.

Uxhuma kanjani i-valve kwipayipi le-PVC?

Uphethe i-valve, kodwa ubheke ipayipi elibushelelezi. Uyazi ukuthi kunezinhlobo ezahlukene zokuxhuma, kodwa iyiphi elungele umsebenzi wakho ukuze uqinisekise isistimu eqinile, engavuzi?

Uxhuma i-valve epayipini le-PVC ngendlela eyodwa yezindlela ezimbili: uxhumano lwe-solvent-weld (isokhethi) unomphela, olungcono kakhulu lwe-PVC-to-PVC, noma uxhumo lwentambo olusevisekayo, olulungele ukuhlanganisa i-PVC nezingxenye zensimbi njengamaphampu.

Ukukhetha indlela efanele kuyisinyathelo sokuqala sokufakwa kochwepheshe. Okwamasistimu angama-PVC ngokuphelele,ukushisela i-solventizinga lemboni. Kwakha ilunga elingenamthungo, elihlanganisiwe eliqine njengepayipi ngokwalo. Inqubo iyashesha, ithembekile, futhi ingunaphakade. Ukuxhuma okunemicu kusetshenziswa uma udinga ukuxhuma ulayini wakho we-PVC kokuthile ngemicu yensimbi ekhona, noma uma ulindele ukuthi udinga ukukhipha ivalvu kalula kamuva. Kodwa-ke, izifakelo zepulasitiki ezinentambo kufanele zifakwe ngokucophelela ukuze kugwenywe imifantu ukuthi ingaqini kakhulu. Ngamapayipi amaningi ajwayelekile e-PVC, ngihlala ngincoma amandla nobulula boxhumano lwe-solvent-weld. Lapho ukusebenza kubalulekile, ai-valve yebhola lenyunyana yeqinisoikunikeza okuhle kakhulu kuyo yomibili imihlaba.

Iyiphi indlela efanele yokufaka i-valve yebhola?

I-valve inamatheliswe kahle, kodwa manje isibambo sishaya odongeni futhi asikwazi ukuvala. Noma ufake i-valve yenhlangano yeqiniso eqine kakhulu endololwaneni kangangokuthi awukwazi ukuthola isikrufu kuyo.

"Indlela efanele" yokufaka i-valve yebhola ukuhlela ukusebenza kwayo. Lokhu kusho ukoma kuqala ukuze kuqinisekiswe ukuthi isibambo sinerediyasi egcwele yokuphenduka engu-90-degree nokuthi amantongomane enyunyana afinyeleleka ngokuphelele ukuze agcinwe esikhathini esizayo.

Ukufakwa okuyimpumelelo kudlulela ngale kwe-auphawu olungavuzi; imayelana nokusebenza kwesikhathi eside. Lapha yilapho umzuzu wokuhlela usindisa ihora lomsebenzi kabusha. Ngaphambi kokuthi uvule i-primer, beka i-valve endaweni oyihlosile bese uswayipha isibambo. Ingabe ihamba ngokukhululeka isuka ekuvulekeni ngokuphelele iye kokuvaleka ngokugcwele? Uma kungenjalo, udinga ukulungisa umumo wayo. Okwesibili, uma usebenzisa ikhwalithi ephezului-valve ye-union yeqinisonjengeyethu e-Pntek, kufanele uqinisekise ukuthi uyakwazi ukufinyelela amantongomane enyunyana. Inhloso yala ma-valve ukuvumela ukukhishwa komzimba we-valve ngaphandle kokusika ipayipi. Ngihlale ngikhumbuza uBudi ukuthi atshele amakhasimende akhe lokhu: uma ungakwazi ukuthola i-wrench kumantongomane, unqobe yonke inhloso ye-valve. Kucabange njengokufakela hhayi okwanamuhla kuphela, kodwa okomuntu okufanele ayisevise eminyakeni emihlanu kusukela manje.

Ingabe ama-valve ebhola e-PVC aqondise?

Usulungile ngosimende, kodwa uyama, ufuna umcibisholo ogelezayo emzimbeni wevalvu. Uyazi ukuthi ukunamathisela i-valve eqondisayo emuva kungaba yinhlekelele, iphutha elibizayo.

Cha, i-valve yebhola ye-PVC evamile ayiqondi; inama-directional amabili. Isebenzisa idizayini elinganayo enezimpawu ezinhlangothini zombili, ukuyivumela ukuthi ivale ukugeleza ngokulinganayo ukusuka kunoma iyiphi indlela. Okuwukuphela “kwenkomba” okufanele ukhathazeke ngayo ukuma kwayo ngokomzimba ukuze kufinyelele isibambo.

Lona umbuzo omuhle kakhulu futhi ojwayelekile. Ukuqapha kwakho kuyafaneleka ngoba amanye ama-valve, afanahlola ama-valvenoma amavalvu embulunga, aqondise ngokuphelele futhi azohluleka uma efakwe emuva. Banomcibisholo ohlukile emzimbeni wokukuqondisa. Ai-valve yebholaNokho, isebenza ngendlela ehlukile. Umnyombo walo yibhola elilula elinembobo phakathi kwalo, elizungezayo ukuze livale esihlalweni. Njengoba kukhona isihlalo ohlangothini oluphezulu nolungezansi lwebhola, idala ukuvala okuqinile kungakhathalekile ukuthi ingcindezi ivela ngayiphi indlela. Ngakho, ungakhululeka. Awukwazi ukufaka ivalvu yebhola ejwayelekile “emuva” ngokuya ngokugeleza. Lo mklamo olula, oqinile ngesinye sezizathu ezenza zidume kangaka. Vele ugxile ekuyibekeni ukuze isibambo nezinyunyana kube lula ukufinyelela kuzo.

Athembeke kangakanani ama-valve ebhola e-PVC?

Ubone i-valve ye-PVC eshibhile, engenagama iqhekeka noma ivuza ngemva konyaka kuphela, okukwenza ubuze into ngokwayo. Uyazibuza ukuthi kufanele yini usebenzise i-valve yensimbi ebiza kakhulu.

Amavalvu ebhola ekhwalithi ephezulu e-PVC athembeke ngokwedlulele futhi angahlala amashumi eminyaka. Ukuphila kwazo kunqunywa ikhwalithi yezinto ezingavuthiwe (i-virgin vs. PVC egaywe kabusha), ukunemba kokukhiqiza, nokufakwa okufanele. Ivalvu yekhwalithi ivamise ukwedlula isistimu ekuyo.

Ukwethembeka kwe-aI-valve yebhola ye-PVCyehlela kulokho eyakhiwe ngakho nokuthi yenziwa kanjani. Lona umnyombo wefilosofi yethu ePntek.

Yini Enquma Ukwethenjelwa?

• Ikhwalithi Yento:Sigcizelela ukusebenzisaI-100% ye-PVC emsulwa. Amavalvu amaningi ashibhile asebenzisa izinto ezigaywe kabusha noma zokugcwalisa, okwenza upulasitiki ube bushelelezi futhi uthambekele ekuhlulekeni ngaphansi kwengcindezi noma ukuchayeka kwe-UV. I-Virgin PVC inikeza amandla aphakeme kanye nokumelana namakhemikhali.
• Ukunemba Kokukhiqiza:Ukukhiqizwa kwethu okuzenzakalelayo kuqinisekisa ukuthi wonke ama-valve ayafana. Ibhola kufanele libe yindilinga ngokuphelele futhi izihlalo zibe bushelelezi ukuze kwakheke uphawu oluqinile. Sicindezela-sivivinya ama-valve ethu abe sezingeni eliphezulu kakhulu kunalokho azoke abone ensimini.
• Idizayini Yokuphila Isikhathi Eside:Izici ezifana nenhlangano yenyunyana yangempela, i-EPDM noma i-FKM O-rings, kanye nomklamo wesiqu esiqinile konke kunomthelela empilweni ende yesevisi. Lona umehluko phakathi kwengxenye yokulahla kanye nempahla yesikhathi eside.

I-valve ye-PVC eyenziwe kahle, efakwe kahle ayiyona isixhumanisi esibuthakathaka; iyisixazululo esiqinile, esingagqwali, futhi esingabizi kakhulu
