Udidwe izinhlobo ezahlukene zama-valve? Ukukhetha engalungile kungasho ukuthi kufanele usike i-valve ekahle epayipini ukuze nje ulungise uphawu oluncane, olugugile.

I-valve yebhola eneziqephu ezimbili iwumklamo ojwayelekile wamavalvu owenziwe ngezingxenye ezimbili zomzimba ezikulungela ndawonye. Lesi sakhiwo sicupha ibhola futhi sivale ngaphakathi, kodwa sivumela i-valve ukuthi ihlakazwe ukuze ilungiswe ngokukhulula umzimba.

Lesi sihloko savela engxoxweni no-Budi, umphathi wokuthenga engisebenza naye e-Indonesia. Ubenekhasimende ebelikhungathekile ngenxa yokuthi i-valve kumugqa wokunisela obucayi waqala ukuvuza. I-valve yayiyimodeli eshibhile, enocezu olulodwa. Nakuba inkinga yayiwuphawu oluncane lwangaphakathi, kwakungekho okunye ababengakwenza ngaphandle kokuvala yonke into, banqamule i-valve yonke epayipini, bese benamathisela entsha. Kwashintsha ukwehluleka kwengxenye yama-dollar amahlanu kwaba umsebenzi wokulungisa owawuthatha isigamu sosuku. Lokho okuhlangenwe nakho kwambonisa ngokushesha ukubaluleka komhlaba wangempela kwe-ai-valve elungisekayo, okusiholele ngqo engxoxweni mayelana nomklamo oneziqephu ezimbili.

Uyini umehluko phakathi kwamavalvu ebhola ayisiqephu esi-1 neziqephu ezi-2?

Ubona ama-valve amabili abukeka afana, kodwa elilodwa libiza kancane. Ukukhetha eshibhile kungase kubonakale kuwukuhlakanipha, kodwa kungakubiza kakhulu ngokusebenza uma kwenzeka yehluleka.

Ivalvu yebhola eyisiqephu esingu-1 inomzimba owodwa, oqinile futhi iyalahlwa; ayikwazi ukuvulwa ukuze ilungiswe. A2-piece valveinomzimba onentambo evumela ukuthi ihlukaniswe, ukuze ukwazi ukufaka esikhundleni izingxenye zangaphakathi njengezihlalo nezimpawu.

Umehluko obalulekile wukusebenza kahle. A1-piece valveyenziwe ngocezu olulodwa lwensimbi. Ibhola nezihlalo zilayishwa ngesinye seziphetho ngaphambi kokuba kuxhunywe ipayipi. Lokhu kuyenza ingabizi kakhulu futhi iqine, ingabi nazimpawu zomzimba ezingavuza. Kodwa uma selakhiwe, livalwa unomphela. Uma isihlalo sangaphakathi siguga ngenxa yegrit noma ukusetshenziswa, i-valve yonke ingudoti. A2-piece valveibiza kancane ngoba inezinyathelo eziningi zokukhiqiza. Umzimba wenziwe izingxenye ezimbili ezihlanganisa ndawonye. Lokhu kusivumela ukuthi siyihlanganise nebhola nezihlalo ngaphakathi. Okubaluleke nakakhulu, ikuvumela ukuthi uyihlukanise kamuva. Kunoma yiluphi uhlelo lokusebenza lapho ukwehluleka kungabangela ubuhlungu bekhanda elikhulu, ikhono lokulungisa i-valve ye-2-piece yenza kube ukukhetha okuphezulu kwesikhathi eside.

1-Piece vs. 2-Piece At-a-Glance

Iyini i-valve enezicucu ezimbili?

Uyalizwa igama elithi “i-valve yeziqephu ezimbili” kodwa lokho kusho ukuthini ngempela? Ukungaqondi lokhu kukhethwa komklamo oyisisekelo kungaholela ekuthengeni i-valve engafanele izidingo zakho.

Ivalve enezicucu ezimbili imane iyivalvu umzimba wayo owakhiwe ezingxenyeni ezimbili eziyinhloko ezihlanganiswe ndawonye, ngokuvamile ngoxhumano olunentambo. Lo mklamo unikeza ibhalansi enkulu phakathi kwezindleko zokukhiqiza kanye nekhono lokusevisa izingxenye zangaphakathi zevalvu.

Kucabange njengendinganiso yemboni yevalvu yebhola elungisekayo, yenhloso ejwayelekile. Umklamo uwukuvumelana. Yethula indlela yokuvuza engase ibe khona endaweni lapho izingcezu ezimbili zomzimba zibophana ndawonye, into evinjwa i-valve yesiqephu esingu-1. Kodwa-ke, leli lungu livikelwe uphawu lomzimba oluqinile futhi lithembeke kakhulu. Inzuzo enkulu lokhu okukudalayo ukufinyelela. Ngokuqaqa leli lunga, ungakwazi ukuya ngqo “emathunjini” evalvu—ibhola kanye nezihlalo ezimbili eziyindilinga elivala ngazo. Ngemva kokuba ikhasimende likaBudi lithole lokho okudidayo, lanquma ukugcina ama-valve ethu aneziqephu ezimbili. Utshela amakhasimende akhe ukuthi ngemali encane eyengeziwe athenge umshwalense. Uma isihlalo sike sahluleka, bangathenga elulaikhithi yokulungisangamadola ambalwa futhi ulungise i-valve, kunokuba ukhokhe i-plumber ukuze abuyisele yonke into.

Iyini i-valve yamabhola amabili?

Wake wezwa igama elithi “two ball valve”? Ukusebenzisa amagama angalungile kungaholela ekudidekeni nasekuhleleni izingxenye ezingalungile, kubangele ukubambezeleka kwephrojekthi nokumosha imali.

“I-valve yebhola emibili” akulona igama lemboni elijwayelekile futhi imvamisa ukulibiza kabi elithi “i-valve yebhola eneziqephu ezimbili.” Ezimweni eziqondile zokusetshenziswa, kungase futhi kusho i-valve yebhola ephindwe kabili, okuyi-valve ekhethekile enamabhola amabili ngaphakathi komzimba owodwa wokuvala ukuvikeleka okuphezulu.

Lokhu kudideka kuvela ngezinye izikhathi, futhi kubalulekile ukucacisa. Amaphesenti angamashumi ayisishiyagalolunye nesishiyagalolunye esikhathi, uma umuntu ecela “i-valve yamabhola amabili,” ukhuluma ngei-valve yebhola eneziqephu ezimbili, ebhekise ekwakhiweni komzimba ebesixoxa ngakho. Nokho, kunomkhiqizo ongavamile kakhulu obizwa ngokuthi ai-valve yebhola kabili. Lona umzimba wevalvu owodwa, omkhulu oqukethe amaqoqo amabili ahlukene ebhola nesihlalo ngaphakathi kwawo. Lo mklamo usetshenziselwa izinhlelo zokusebenza ezibucayi (ngokuvamile embonini kawoyela negesi) lapho udinga khona "i-double block kanye nokopha." Lokhu kusho ukuthi ungakwazi ukuvala womabili ama-valve bese uvula ipayipi elincane phakathi kwawo ukuze uqinisekise ngokuphephile ukuvala okuphelele, okungu-100% okungavuzi. Kuzinhlelo zokusebenza ezijwayelekile ze-PVC ezifana nokufaka amapayipi nokunisela, awusoze wahlangabezana ne-valve yebhola ephindwe kabili. Igama odinga ukulazi lithi "iziqephu ezimbili."

Yiziphi izinhlobo ezintathu zama-valve ebhola?

Ufunde ngamavalvu anocezu olu-1 kanye neziqephu ezi-2. Kodwa kuthiwani uma udinga ukulungisa ngaphandle kokuvala uhlelo lonke amahora? Kukhona uhlobo lwesithathu lwalokho kanye.

Izinhlobo ezintathu eziyinhloko zama-valve ebhola, ezihlukaniswe ngokwakhiwa komzimba, ziyi-1-piece, 2-piece, kanye ne-3-piece. Bamele isikali esisuka ezindlekweni eziphansi kakhulu futhi akukho ukulungiseka (ucezu olu-1) ukuya ezindlekweni eziphakeme kakhulu kanye nokusebenza okulula (3-piece).

Sihlanganise ezimbili zokuqala, ngakho-ke ake siqedele isithombe ngohlobo lwesithathu. A3-piece ibhola valveiwumklamo okhokhelwayo, onesevisi kalula kakhulu. Iqukethe ingxenye yomzimba emaphakathi (ephethe ibhola nezihlalo) kanye namakepisi amabili ahlukene axhunywe epayipini. Lezi zingxenye ezintathu zibanjwe ndawonye ngamabhawodi amade. Umlingo walo mklamo yukuthi ungashiya ama-caps wokugcina ahlanganiswe nepayipi futhi umane uvule umzimba oyinhloko. Ingxenye emaphakathi ibe “iphuma,” ikunikeza ukufinyelela okuphelele ukuze ulungiseke ngaphandle kokusika ipayipi. Lokhu kubaluleke kakhulu ezimbonini noma kuzilungiselelo zezohwebo lapho ukungasebenzi kwesistimu kubiza kakhulu. Ivumela i-ukugcinwa okushesha kakhulu okungenzeka. Manje uBudi unikeza amakhasimende akhe zontathu izinhlobo, ewaqondisa ekukhetheni okufanele ngokusekelwe kubhajethi yawo kanye nokuthi isicelo sawo sibaluleke kangakanani.

Ukuqhathaniswa kwamavalvu ebhola angu-1, 2, kanye no-3-Piece

Isiphetho

Ai-valve yebhola eneziqephu ezimbiliinikeza ukulungiseka ngokuba nomzimba okhulula izikulufu. Kuyindawo emaphakathi enhle phakathi kwesiqephu esingu-1 esilahlwayo kanye namamodeli wamavalvu angama-3 aneziqephu ezi-3 asebenza ngokugcwele.
