Udidekile ngezinhlobo ezahlukene zamavalvu? Ukukhetha elingalungile kungasho ukuthi kufanele usike ivalvu enhle kakhulu epayipini ukuze ulungise uphawu oluncane, olugugile.

I-valve yebhola enezicucu ezimbili iwumklamo ovamile we-valve owenziwe ngezingxenye ezimbili zomzimba eziyinhloko ezihlanganisa ndawonye. Lokhu kwakhiwa kubopha ibhola bese kuvala ngaphakathi, kodwa kuvumela i-valve ukuthi ihlukaniswe ukuze ilungiswe ngokuyikhulula emzimbeni.

Lesi sihloko sivele engxoxweni noBudi, umphathi wokuthenga engisebenza naye e-Indonesia. Wayenekhasimende elalikhungathekile ngoba ivalvu emugqeni wokunisela obalulekile yaqala ukuvuza. Ivalvu yayishibhile, imodeli eyodwa. Ngisho noma inkinga yayiwuphawu lwangaphakathi oluncane, babengenakho okunye ngaphandle kokuvala yonke into, banqume yonke ivalvu epayipini, bese benamathisela entsha. Kwaguqula ukwehluleka kwezingxenye zamadola amahlanu kwaba umsebenzi wokulungisa isigamu sosuku. Lokho okuhlangenwe nakho kwambonisa ngokushesha inani langempela le-ivalvu elungisekayo, okwasiholela ngqo engxoxweni mayelana nomklamo wezingxenye ezimbili.

Uyini umehluko phakathi kwamavalvu ebhola angu-1 kanye namavalvu ebhola angu-2?

Ubona ama-valve amabili afanayo, kodwa elinye libiza kancane. Ukukhetha elishibhile kungase kubonakale kuhlakaniphile, kodwa kungabiza kakhulu ekuzaleni uma kwenzeka lehluleka.

Ivalvu yebhola enesiqephu esisodwa inomzimba owodwa, oqinile futhi ingasetshenziswa ngokuzenzakalelayo; ayikwazi ukuvulwa ukuze ilungiswe.ivalvu enezingcezu ezimbiliinomzimba onentambo ovumela ukuthi uhlukaniswe, ngakho-ke ungashintsha izingxenye zangaphakathi njengezihlalo nezivalo.

Umehluko oyinhloko ukulungiselelwa kwesevisi.ivalvu enesiqephu esisodwaKwenziwe ngengcezu eyodwa yezinto ezibunjiwe. Ibhola nezihlalo kulayishwa ngenye yezingxenye ngaphambi kokuba kuhlanganiswe ipayipi. Lokhu kwenza kube okungabizi kakhulu futhi kuqine, kungabi nazimpawu zomzimba ezivuzayo. Kodwa uma sekwakhiwe, kuvalwa unomphela. Uma isihlalo sangaphakathi siguga ngenxa yokungcola noma ukusetshenziswa, ivalvu yonke iwudoti.ivalvu enezingcezu ezimbiliIbiza kancane ngoba inezinyathelo eziningi zokukhiqiza. Umzimba wenziwe ngezigaba ezimbili ezihlangana ndawonye. Lokhu kusenza sikwazi ukuwuhlanganisa nebhola futhi sihlale ngaphakathi. Okubaluleke kakhulu, kukuvumela ukuthi uwuhlukanise kamuva. Kunoma yikuphi ukusetshenziswa lapho ukwehluleka kungadala ikhanda elikhulu, ikhono lokulungisa ivalvu enezingcezu ezimbili lenza kube ukukhetha okuhle kwesikhathi eside.

Ingxenye E-1 vs. Ingxenye E-2 Ngokubuka Nje

Iyini ivalvu enezicucu ezimbili?

Uzwa igama elithi “ivalvu enezicucu ezimbili” kodwa lokho kusho ukuthini ngempela? Ukungaqondi lokhu kukhetha okuyisisekelo kokuklama kungakuholela ekuthengeni ivalvu engayifanele izidingo zakho.

Ivalvu enezicucu ezimbili imane iyivalvu umzimba wayo owakhiwe ngezingxenye ezimbili eziyinhloko ezihlanganiswe ndawonye, ​​​​ngokuvamile ngokuxhumeka okunezintambo. Lo mklamo unikeza ibhalansi enhle phakathi kwezindleko zokukhiqiza kanye nekhono lokunakekela izingxenye zangaphakathi zevalvu.

Cabanga ngakho njengendinganiso yemboni yevalvu yebhola elungisekayo, esetshenziswa kabanzi. Umklamo uwukuvumelana. Wethula indlela engaba khona yokuvuza lapho izingxenye ezimbili zomzimba zihlangana khona, into ivalvu yesiqephu esisodwa eyigwemayo. Kodwa-ke, leli joyinti livikelwe uphawu lomzimba oluqinile futhi lithembekile kakhulu. Inzuzo enkulu edalwa yilokhu ukufinyelela. Ngokukhulula leli joyinti, ungafinyelela ngqo "emathunjini" evalvu—ibhola kanye nezihlalo ezimbili eziyindilinga elizibopha kuzo. Ngemva kokuba ikhasimende likaBudi libe nalolo lwazi olukhungathekisayo, lanquma ukugcina amavalvu ethu ezingxenye ezimbili. Utshela amakhasimende akhe ukuthi ngezindleko ezincane ezengeziwe kusengaphambili, bathenga inqubomgomo yomshuwalense. Uma isihlalo sike sehluleka, bangathenga elulaikhithi yokulungisangamadola ambalwa bese ngilungisa ivalvu, kunokukhokha umbhobho ukuze ashintshe yonke into.

Iyini ivalvu yamabhola amabili?

Wake wezwa igama elithi “ama-valve amabili”? Ukusebenzisa amagama angalungile kungaholela ekudidekeni nasekuhleleni izingxenye ezingalungile, okubangela ukubambezeleka kwephrojekthi kanye nokuchitha imali.

Igama elithi “Two ball valve” akulona igama elijwayelekile embonini futhi ngokuvamile liyigama elingalungile elithi “ivalvu yebhola enezingcezu ezimbili.” Ezimweni zokusetshenziswa okuqondile kakhulu, kungasho futhi ivalvu yebhola eliphindwe kabili, okuyivalvu ekhethekile enamabhola amabili ngaphakathi komzimba owodwa ukuze kuvalwe ngokuphepha okukhulu.

Lokhu kudideka kuvela ngezinye izikhathi, futhi kubalulekile ukucacisa. Amaphesenti angamashumi ayisishiyagalolunye nesishiyagalolunye esikhathi, lapho umuntu ecela “i-valve yamabhola amabili,” ukhuluma nge-ivalvu yebhola enezingcezu ezimbili, sibhekisela ekwakhiweni komzimba ebesixoxa ngakho. Kodwa-ke, kukhona umkhiqizo ongavamile kakhulu obizwa ngokuthiivalvu yebhola ephindwe kabili. Lona umzimba wevalvu owodwa, omkhulu oqukethe izinhlangano ezimbili ezihlukene zebhola nezihlalo ngaphakathi kuwo. Lo mklamo usetshenziselwa izinhlelo ezibalulekile (ngokuvamile embonini kawoyela negesi) lapho udinga khona "i-double block and bleeding." Lokhu kusho ukuthi ungawavala womabili amavalvu bese uvula ipayipi elincane phakathi kwawo ukuqinisekisa ngokuphephile ukuvalwa okuphelele, okungavumeli ukuvuza okungu-100%. Ezinhlelweni ze-PVC ezijwayelekile ezifana namapayipi kanye nokunisela, cishe awusoze wahlangana nevalvu yebhola eliphindwe kabili. Igama okudingeka ulazi lithi "izingxenye ezimbili."

Ukuhlanza Amagama Asetshenziswayo

Yiziphi izinhlobo ezintathu zama-ball valve?

Usufundile ngamavalvu angu-1 kanye nangu-2. Kodwa kuthiwani uma udinga ukulungisa ngaphandle kokuvala lonke uhlelo amahora amaningi? Kukhona uhlobo lwesithathu lwalokho kanye.

Izinhlobo ezintathu eziyinhloko zamavalvu ebhola, ahlukaniswe ngokwakhiwa komzimba, yi-1-piece, 2-piece, kanye ne-3-piece. Zimelela isikali kusukela ezindleko eziphansi kakhulu kanye nokungalungiseki (1-piece) kuya ezindleko eziphezulu kakhulu kanye nokulungiseka okulula (3-piece).

Sesihlanganise ezimbili zokuqala, ngakho-ke ake siqedele isithombe ngohlobo lwesithathu.I-valve yebhola enezingcezu ezintathuyiklamo esezingeni eliphezulu, elula kakhulu ukuyilungisa. Iqukethe ingxenye yomzimba ephakathi (ebamba ibhola nezihlalo) kanye nezimbobo ezimbili ezihlukene ezixhunywe epayipini. Lezi zingxenye ezintathu zibanjwe ndawonye ngamabhawodi amade. Umlingo walo mklamo ukuthi ungashiya izimbobo zokugcina zinamathele epayipini bese umane ukhulule umzimba oyinhloko. Ingxenye ephakathi bese "iphuma," ikunikeze ukufinyelela okuphelele kokulungisa ngaphandle kokudinga ukusika ipayipi. Lokhu kubaluleke kakhulu ezimbonini noma ezindaweni zezentengiselwano lapho isikhathi sokungasebenzi kwesistimu sibiza kakhulu. Kuvumelaukulungiswa okusheshayo ngangokunokwenzeka. UBudi manje unikeza amakhasimende akhe zonke izinhlobo ezintathu, ebaqondisa ekukhetheni okulungile ngokusekelwe kwisabelomali sabo nokuthi isicelo sabo sibaluleke kangakanani.

Ukuqhathaniswa kwama-valve ebhola angu-1, 2, kanye no-3-Piece

Isiphetho

Aivalvu yebhola enezingcezu ezimbiliinikeza ukulungiswa kalula ngokuba nomzimba ovulekayo. Kuyindawo ephakathi nendawo enhle phakathi kwe-1-piece elahlwayo kanye namamodeli e-valve e-3-piece angasetshenziswa ngokugcwele emgqeni.
