Udinga i-valve enamandla kunocezu olulodwa kodwa hhayi njengenani elilingana nocezu oluthathu. Ukukhetha engalungile kusho ukukhokha ngokweqile noma ukuthola i-valve ongeke ukwazi ukuyilungisa uma kubalulekile.

I-valve yebhola eneziqephu ezimbili iqukethe izingxenye ezimbili ezibalulekile zomzimba ezibophana ndawonye, zicuphe ibhola futhi zivale ngaphakathi. Lo mklamo unamandla kune-valve yesiqephu esisodwa futhi uvumela ukulungiswa, nakuba kufanele uqale ususwe epayipini.

I-valve yebhola eneziqephu ezimbili iyihhashi leqiniso emhlabeni wamapayipi. Kungolunye lwezinhlobo ezivame kakhulu engixoxa ngazo nozakwethu, njengo-Budi, umphathi wokuthenga e-Indonesia. Amakhasimende akhe, iningi lawo angosonkontileka abajwayelekile nabasabalalisi, adinga isisombululo esithembekile, esingabizi kakhulu semisebenzi yansuku zonke. Idizayini eneziqephu ezimbili ifinyelela leyo ndawo emnandi kahle. Inikeza ukuthuthukiswa okuphawulekayo kwamandla nokusebenza phezu kwama-valve ayisisekelo kakhulu ngaphandle kwezindleko eziphakeme zamamodeli ezimboni eziyinkimbinkimbi. Ukuze uqonde ukubaluleka kwayo ngempela, kufanele ubone lapho ingena khona esithombeni esikhulu.

Iyini i-valve enezicucu ezimbili?

Ungabona umthungo lapho umzimba we-valve uhlanganiswe khona, kodwa lokho kusho ukuthini? Ukuqonda ukwakhiwa kwayo kuyisihluthulelo sokwazi ukuthi ingabe kuyisinqumo esifanele sempilo yesikhathi eside yesistimu yakho.

Ivalvu enezicucu ezimbili inomzimba omkhulu kanye nocezu lwesibili, isixhumi sokugcina, esingena kuso. Lokhu kuxhumana okucushiwe kugcina ibhola nezihlalo, okwenza ivalvu isebenze futhi imelane nokucindezela kunomklamo wocezu olulodwa.

Ukwakhiwa kwe-ai-valve enezicucu ezimbiliisici sayo esiyinhloko. Cabanga ukuthi umzimba we-valve wenziwe ngezigaba ezimbili. Ingxenye enkulu ibamba isiqu nesibambo, kuyilapho ingxenye encane iyikepisi elinentambo. Uma zihlanganiswe ndawonye, zibambelela ebholeni nasezihlalweni ezithambile (ezivamise ukwakhiwa nge-PTFE) ezidala uphawu. Lo mklamo womzimba onentambo unamandla kakhulu kunevalvu yocezu olulodwa, lapho ibhola lifakwa khona ngembobo encane, ngokuvamile edinga ibhola elincane (imbobo encishisiwe). Ukwakhiwa kwezingxenye ezimbili kuvumela ibhola elikhulu, "imbobo egcwele", okusho ukuthi imbobo yebhola ilingana nepayipi, okuholela ekugelezeni okungcono nokulahlekelwa kwengcindezi encane. Uma uphawu luke luguge, ungakhulula umzimba, ubuyisele izingxenye, bese uwubuyisela emsebenzini. Kuyindawo ephakathi nendawo kumakhasimende amaningi e-Budi adinga ivalvu eqinile nelungisekayo.

Uyini umehluko phakathi kwe-valve yebhola yohlobo 1 nohlobo 2?

Uzwa amagama afana nokuthi “Uhlobo 1″ kanye “nohlobo 21” kodwa ungaqiniseki ukuthi asho ukuthini. Ukukhetha ngokusekelwe kule migomo ngaphandle kokuyiqonda kungase kusho ukuphuthelwa izici ezibalulekile zokuphepha.

Lawa magama awabhekiseli ekwakhiweni komzimba (njengezingcezu ezimbili) kodwa ekudizayineni izizukulwane, imvamisa yamavalvu amayunithi eqiniso. “Uhlobo 21″ luwukunqamulela komkhakha wedizayini yesimanje enezici ezithuthukisiwe zokuphepha nokusebenziseka.

Kubaluleke kakhulu ukuthi ungaphambanisi isitayela somzimba ngalezi zinombolo “zohlobo”. Ivalvu "eziqephu ezimbili" ichaza indlela umzimba owakhiwe ngayo ngokomzimba. Amagama afana nokuthi "Uhlobo 21," ngakolunye uhlangothi, achaza isethi ethile yezici zesimanje, futhi cishe atholakala njalo kumavalvu amayunithi eqiniso anezingxenye ezintathu. Kufanele ngikucacisele lokhu eqenjini likaBudi ngezinye izikhathi. Ikhasimende lingase licele a"I-valve yohlobo lwama-21 eneziqephu ezimbili,"kodwa lezo zici ziyingxenye yesigaba se-valve esihlukile. Isici esibaluleke kakhulu sesitayela se-Type 21 yi-i-block-safe union nut, okuvimbela i-valve ukuthi ingafihli ngengozi futhi ivuleke ngenkathi isistimu ingaphansi kwengcindezi. Lesi isici sokuphepha esibalulekile. Futhi ngokuvamile zihlanganisa i-double stem O-rings yokuvala isibambo kangcono kanye nephedi yokukhweza eyakhelwe ngaphakathi yokwengeza i-actuator. Lezi izici ze-premium zemisebenzi enzima kakhulu, kanti i-valve ejwayelekile eneziqephu ezimbili iyisinqumo esithembekile somsebenzi wenhloso evamile.

Isetshenziselwa ini i-valve yebhola elinezinhlangothi ezimbili?

Udinga ukumisa noma uqale ukugeleza kwamanzi. Ngazo zonke izinhlobo zama-valve eziyinkimbinkimbi ezitholakalayo, kulula ukwenza inkimbinkimbi yesixazululo futhi usebenzise ngokweqile izici ezingadingekile zomsebenzi.

I-valve yebhola enezinhlangothi ezimbili isetshenziselwa ukulawula okuyisisekelo kokuvula/ukuvala epayipini eliqondile. Inamachweba amabili—i-inlet ne-outlet—futhi inikeza indlela elula, ethembekile yokuvala ukugeleza kwezinhlelo zokusebenza ezingenakubalwa.

I-valve enezinhlangothi ezimbili iwuhlobo oluvame kakhulu lwe-valve ekhona. Yenza umsebenzi owodwa: ihlukanisa ukuhamba. Kucabange njengokushintsha ukukhanya kwamanzi—kungaba kuvuliwe noma kuvaliwe. Iningi lama-valve ebhola oyoke uwabone, okuhlanganisa cishe nawo wonke ama-valve aneziqephu ezimbili, angama-two-way valve. Ziwumgogodla wezinhlelo zamapayipi yonke indawo. Uwasebenzisela ukuvala amanzi endaweni yokufafaza, ukuhlukanisa ucezu lwesisetshenziswa ukuze lulungiswe, noma njengendawo yokuvala enkulu yesakhiwo. Ubulula bazo ngamandla abo. Lokhu kuhlukile kuma-valve anezimbobo eziningi, njenge-valve enezinhlangothi ezintathu, eklanyelwe ukuphambukisa ukugeleza, njengokuthumela amanzi phansi ngendlela eyodwa noma enye. Kumaphesenti angama-95 emisebenzi amakhasimende kaBudi abhekana nayo, i-valve elula, eqinile, enezinhlangothi ezimbili iyithuluzi elilungile. Idizayini eneziqephu ezimbili iyisinqumo esihle futhi esivame kakhulu kulo msebenzi obalulekile.

Uyini umehluko phakathi kwesiqephu esisodwa nevalve yebhola eneziqephu ezintathu?

Ukhetha phakathi kwevalve eshibhe kakhulu nebiza kakhulu. Ukwenza ukukhetha okungalungile kusho ukuthi awukwazi ukulungisa inkinga noma umoshe imali ezicini ongeke neze uzisebenzise.

Umehluko obalulekile wukusebenza. I-valve yocezu olulodwa iyiyunithi evaliwe, elahlwayo. I-valve enezicucu ezintathu ingalungiswa kalula ngenkathi isaxhunywe epayipini. I-valve enezicucu ezimbili ihlala phakathi.

Ukuqonda ucezu olulodwa kanye nezinketho zezingxenye ezintathu kukhombisa ngempela ukuthi kungani i-valve eneziqephu ezimbili idume kakhulu. Aucezu olulodwai-valve yenziwe ngomzimba owodwa, okwenza ingabizi kodwa ingakwazi ukuyivula ukuze ilungiswe. Kuyinto "yokusebenzisa futhi ubeke esikhundleni" ehamba phambili emigqeni engabalulekile. Ngakolunye uhlangothi yi-i-valve enezingxenye ezintathu. Inomzimba omaphakathi nezixhumi ezimbili ezihlukene eziphethwe ndawonye ngamabhawudi amade. Lo mklamo ikuvumela ukuthi ususe yonke ingxenye emaphakathi yevalvu ukuze ushintshe izimpawu ngaphandle kokusika ipayipi. Lokhu ukukhetha okuphezulu kwezitshalo zezimboni noma amachibi okuhweba lapho isikhathi sokuphumula sibiza kakhulu. Iiziqephu ezimbilii-valve inikeza ukuyekethisa okuphelele. Iqine kakhulu futhi ivamise ukuba nokugeleza okungcono kunocezu olulodwa, futhi iyalungiseka. Nakuba kufanele uyisuse emugqeni ukuze uyilungise, lokho kuwukuhwebelana okwamukeleka ngokuphelele ngentengo ephansi uma kuqhathaniswa nevalvu eneziqephu ezintathu.

I-Valve Body Ukuqhathanisa Ukuqhathanisa

Isiphetho

A i-valve yebhola eneziqephu ezimbiliiyihhashi elithembekile, elilungisekayo. Inikeza ibhalansi ephelele yamandla nezindleko phakathi kocezu olulodwa olulahlwayo kanye nensizakalo ephezulu, imiklamo eyizingcezu ezintathu yezinhlelo zokusebenza eziningi.
