Udinga ukulawula ukugeleza kwamanzi ohlelweni olusha lwamapayipi. Ubona “i-PVC ball valve” ohlwini lwezingxenye, kodwa uma ungazi ukuthi iyini, awukwazi ukuqiniseka ukuthi iyisinqumo esifanele somsebenzi.
I-valve yebhola ye-PVC iyi-valve eqinile yepulasitiki evalayo esebenzisa ibhola elijikelezayo elinembobo kulo ukulawula ukugeleza koketshezi. Yenziwe nge-Polyvinyl Chloride, ishibhile futhi imelana kakhulu nokugqwala nokugqwala.
Lona umkhiqizo wokuqala engiwunikeza abalingani abasha njengoBudi e-Indonesia.I-valve yebhola ye-PVCkuyisisekelo sesimanjeukuphathwa kwamanzi. Kulula, kuthembekile, futhi kuyaguquguquka ngendlela emangalisayo. Kumphathi wokuthenga njengoBudi, ukuqonda okujulile ngalo mkhiqizo oyinhloko kubalulekile. Akukhona nje ukuthenga nokuthengisa ingxenye; kumayelana nokunikeza amakhasimende akhe ikhambi elithembekile lakho konke kusukelaukunisela ekhayakumaphrojekthi amakhulu ezimboni. Ubambiswano oluzuzisa bonke luqala ngokuqonda izinto eziyisisekelo ndawonye.
Iyini injongo yevalvu yebhola le-PVC?
Unepayipi futhi udinga ukulawula ukuthi yini egeleza kulo. Ngaphandle kwendlela ethembekile yokumisa ukugeleza, noma yikuphi ukulungiswa noma ukulungiswa kuzoba yinkathazo enkulu.
Inhloso eyinhloko yevalvu yebhola ye-PVC ukunikeza ukulawula okusheshayo nokuphelele kokuvula/ukuvala ohlelweni loketshezi. Ukujika okusheshayo kwesibambo kungamisa ngokuphelele noma kuvumele ukugeleza ngokugcwele.
Cabanga ngakho njengesibani sokukhanyisa amanzi. Umsebenzi waso oyinhloko akukhona ukulawula inani lokugeleza kwamanzi, kodwa ukuwuqala noma ukuwumisa ngokuqinile. Lo msebenzi ubalulekile ezinhlotsheni eziningi. Isibonelo, amakhasimende kaBudi asebenza ngokwakha asebenzisa wona ukuhlukanisa izingxenye zesistimu yamapayipi. Uma into eyodwa idinga ukulungiswa, angavala amanzi aye kuleyo ndawo encane esikhundleni sesakhiwo sonke. Ekuniseleni, bawasebenzisa ukuqondisa amanzi ezindaweni ezahlukene. Emachibini nasezindaweni zokuchelela, balawula ukugeleza kwamanzi kuya kumaphampu, ezihlungini, nasezifudumezini. Isenzo esilula nesisheshayo seivalvu yebholakwenza kube ithuluzi elibalulekile lokuqinisekisa ukuvala okuhle, ukuqinisekisa ukuphepha nokulawula lonke uhlelo. Kwa-Pntek, siklama amavalvu ethu ukuze kube nesivalo esiphelele, ngakho-ke uma ivaliwe, ihlala ivaliwe.
Kusho ukuthini ibhola le-PVC?
Uzwa igama elithi “ibhola le-PVC” futhi lizwakala lincane noma lidida. Ungase ucabange ukuthi libhekisela engxenyeni ehlukile, okwenza kube nzima ukuqonda umkhiqizo nokubeka i-oda elinembile.
“Ibhola le-PVC” lichaza izingxenye ezimbili eziyinhloko zevalvu uqobo. “I-PVC” yinto, i-Polyvinyl Chloride, esetshenziselwa umzimba. “Ibhola” liyindilinga ejikelezayo ngaphakathi evimba ukugeleza.
Ake sichaze igama, njengoba ngivame ukwenza kubathengisi abasha bakaBudi. Akuyona into eyinkimbinkimbi njengoba kuzwakala.
- I-PVC (i-Polyvinyl Chloride):Lolu uhlobo oluthile lwepulasitiki eqinile neqinile umzimba wevalvu owenziwe ngayo. Sisebenzisa i-PVC ngoba iyinto enhle kakhulu yezinhlelo zamanzi. Ilula, okwenza kube lula ukuyiphatha nokuyifaka. Iphinde imelane nokugqwala nokugqwala, ngokungafani namavalvu ensimbi angawohloka ngokuhamba kwesikhathi, ikakhulukazi ngamakhemikhali athile noma amanzi aqinile. Okokugcina, ingabizi kakhulu.
- Ibhola:Lokhu kubhekisela endleleni esebenza ngayo ngaphakathi kwevalvu. Kuyisiyingi esinembobo (i-port) ebholwe ngqo kuyo. Uma ivalvu ivulekile, leyo mbobo ihambisana nepayipi. Uma uphendula isibambo, ibhola lijikeleza ama-degree angu-90, kanti uhlangothi oluqinile lwebhola luvimba ipayipi.
Ngakho-ke, elithi “i-PVC ball valve” lisho nje i-valve eyenziwe ngezinto ze-PVC esebenzisa indlela yebhola.
Yiliphi i-brass noma i-PVC ball valve engcono?
Unquma phakathi kwethusi ne-PVC yephrojekthi. Ukukhetha izinto ezingalungile kungaholela ekuhlulekeni kwangaphambi kwesikhathi, ukweqisa isabelomali, noma ngisho nokungcola, okubeka idumela lakho engcupheni.
Akukho okungcono; kungenxa yemisebenzi ehlukene. I-PVC ilungele amanzi abandayo, izintambo zamakhemikhali, kanye namaphrojekthi azwela izindleko ngoba ayigqwali futhi ayibizi. Ithusi lingcono kakhulu emazingeni okushisa aphezulu kanye nokucindezela.
Lona umbuzo ovamile kumakhasimende kaBudi, futhi impendulo efanele ikhombisa ubuchwepheshe bangempela. Ukukhetha kuncike ngokuphelele ezidingweni ezithile zohlelo lokusebenza. Ngihlala ngincoma ukusebenzisa ithebula lokuqhathanisa elilula ukuze ngicacise isinqumo.
| Isici | I-PVC Ball Valve | I-Brass Ball Valve |
|---|---|---|
| Ukumelana Nokugqwala | Kuhle kakhulu. Ayikwazi ukugqwala. | Kuhle, kodwa kungaguguleka ngamanzi aqinile noma amakhemikhali. |
| Izindleko | Iphansi. Ingabizi kakhulu. | Iphakeme. Ibiza kakhulu kune-PVC. |
| Umkhawulo Wezinga Lokushisa | Ngaphansi. Ngokuvamile kufika ku-140°F (60°C). | Iphakeme. Ingaphatha amanzi ashisayo kanye nomusi. |
| Isilinganiso Sokucindezela | Kuhle kakhulu ezinhlelweni eziningi zamanzi. | Kuhle kakhulu. Iyakwazi ukumelana nokucindezeleka okuphezulu kakhulu. |
| Ukufakwa | Ilula. Isebenzisa usimende we-PVC olula. | Kunzima. Kudinga ukusonta kanye nezinkinobho zamapayipi. |
| Okuhle Kakhulu Kwaba | Ukunisela, amachibi okubhukuda, ukwelashwa kwamanzi, amapayipi ajwayelekile. | Imigqa yamanzi ashisayo, izinhlelo zezimboni ezinomfutho ophezulu. |
Emisebenzini eminingi yokuphathwa kwamanzi, i-PVC inikeza ibhalansi engcono kakhulu yokusebenza kanye nenani.
Iyini injongo yevalvu ye-PVC?
Ubona ivalvu ye-PVC njengengxenye eyodwa kuphela. Lo mbono omncane ungase ukwenze uphuthelwe umbono obanzi wokuthi kungani ukusebenzisa i-PVC ohlelweni lonke kuyisinqumo esihlakaniphile kangaka.
Inhloso yevalvu ye-PVC ukulawula ukugeleza kwamanzi kusetshenziswa into engabizi, elula, futhi engagqwali. Ihlinzeka ngesisombululo esithembekile nesihlala isikhathi eside ngaphandle kwezindleko noma ubuthakathaka bamakhemikhali bensimbi.
Nakuba umsebenzi wevalvu eyodwa ukuvimba amanzi, inhloso yokukhethaI-PVCngoba lelo valve liyisinqumo esibalulekile kulo lonke uhlelo. Uma iphrojekthi isebenzisa amapayipi e-PVC, ukuwahlanganisa nama-valve e-PVC kuyisinqumo esihlakaniphile kakhulu. Kwakha uhlelo olungenamthungo nolufanayo. Usebenzisa usimende ofanayo we-solvent kuzo zonke izixhumanisi, okwenza kube lula ukufakwa futhi kunciphise amathuba amaphutha. Ususa ingozi yokuthiukugqwala kwe-galvanic, okungenzeka uma uxhuma izinhlobo ezahlukene zensimbi epayipini. KuBudi njengomsabalalisi, ukugcina uhlelo lwamapayipi e-PVC, izinto zokufaka, kanye namavalvu ethu e-Pntek kusho ukuthi anganikeza amakhasimende akhe ikhambi eliphelele nelihlanganisiwe. Akukhona nje ukuthengisa ivalvu; kumayelana nokuhlinzeka ngezingxenye zesistimu yokuphatha amanzi ethembekile, engabizi, futhi ehlala isikhathi eside.
Isiphetho
A I-valve yebhola ye-PVCiyithuluzi elingagqwali, elingabizi kakhulu lokulawula ukugeleza kokuvula/ukuvala. Umklamo wayo olula kanye nezakhiwo ezinhle kakhulu ze-PVC kwenza kube ukukhetha okujwayelekile kwezinhlelo zamanzi zesimanje.
