Ucabanga ukuthi ivalvu yakho ivumela ukugeleza okuphezulu, kodwa uhlelo lwakho alusebenzi kahle. Ivalvu oyikhethile ingase ivimbe umugqa, inciphise ukucindezela nokusebenza kahle ngokuthula ngaphandle kokuthi wazi ukuthi kungani.

Akuwona wonke ama-valve ebhola e-PVC ane-port egcwele. Amaningi ayi-port ejwayelekile (ebizwa nangokuthi i-reduced port) ukuze kongiwe izindleko nendawo. I-valve egcwele inembobo enobukhulu obufana nobepayipi ukuze kugeleze amanzi ngaphandle kokuvinjelwa ngokuphelele.

Lena imininingwane ebalulekile ekwakhiweni kwesistimu, futhi yinto engixoxa ngayo njalo nabalingani bami, okuhlanganisa nethimba likaBudi e-Indonesia. Ukukhetha phakathi kwechweba eligcwele nechweba elijwayelekile kuthinta ngqo ukusebenza kwesistimu. Kumakhasimende kaBudi angamakhontrakthi, ukwenza lokhu kahle kusho umehluko phakathi kwesistimu esebenza kahle kanye nesistimu engahlangabezani nokulindelwe. Ngokuqonda lo mehluko, bangakhetha i-valve ye-Pntek ephelele yomsebenzi ngamunye, baqinisekise ukwaneliseka kwamakhasimende futhi bakhe idumela labo ngomsebenzi osezingeni eliphezulu.

Ingabe i-ball valve iyi-full port valve?

Udinga ukugeleza okuphezulu kakhulu ohlelweni lwakho olusha lwephampu. Kodwa ngemva kokufakwa, ukusebenza kuyadumaza, futhi usola ukuthi kukhona ukuvinjelwa endaweni ethile emgqeni, mhlawumbe kusuka ku-valve yokuvala oyisebenzisile.

I-valve yebhola ingaba yi-port egcwele noma i-port ejwayelekile. Imbobo ye-valve egcwele (umgodi) ifana nobubanzi bangaphakathi bepayipi ukuze kube nokuvinjelwa kokugeleza okungu-zero. I-port ejwayelekile incane ngosayizi wepayipi elilodwa.

Igama "imbobo egcwele"(noma i-full bore) isici esithile sokuklama, akuyona ikhwalithi ebanzi yawo wonke ama-ball valve. Ukwenza lokhu kuhluka kuyisihluthulelo sokukhetha ama-valve afanele. I-full port valve yenzelwe ukusebenza kahle okukhulu kokugeleza. Imbobo ebholeni inkulu kakhulu ukuze ifane nobubanzi bangaphakathi bepayipi elixhunywe kuyo. Ai-valve yembobo ejwayelekileNgokuphambene nalokho, inomgodi omncane kakhulu kunombhobho. Lokhu kudala ukuvinjelwa okuncane.

Ngakho-ke, kufanele uyisebenzise nini ngayinye? Nansi isiqondiso esilula engisinikeza ozakwethu.

Eziningi zezicelo zansuku zonke, njengomugqa wegatsha oya kusinki noma endlini yangasese, ivalvu ejwayelekile yokuvala igesi ilungile ngokuphelele futhi ingabizi kakhulu. Kodwa kumugqa wamanzi oyinhloko noma ukuphuma kwephampu, ivalvu egcwele yokuvala igesi ibalulekile ukuze kulondolozwe ingcindezi nokugeleza kwamanzi.

Iyini i-valve yebhola ye-PVC?

Udinga indlela elula nethembekile yokuvimba amanzi. Amavalvu esango akudala ayaziwa ukuthi ayabamba noma avuza uma uwavala, futhi udinga ivalvu esebenza njalo.

I-valve yebhola ye-PVC iyi-valve yokuvala esebenzisa ibhola elijikelezayo elinembobo phakathi kwalo. Ukujika okusheshayo kwesibambo kuqondanisa imbobo nepayipi ukuze liyivule noma kuyiphendulele ekugelezeni ukuze ivinjwe.

II-valve yebhola ye-PVCithandwa ngobulula bayo obuhle kakhulu kanye nokuthembeka kwayo okumangalisayo. Ake sibheke izingxenye zayo eziyinhloko. Iqala ngomzimba we-PVC oqinile ohlanganisa konke ndawonye. Ngaphakathi kuhlezi inhliziyo yevalvu: ibhola le-PVC eliyindilinga elinembobo ebholwe ngokunembile, noma "ibhobo," elidlula phakathi nendawo. Leli bhola lihlala phakathi kwezindandatho ezimbili ezibizwa ngokuthi izihlalo, ezenziwe ngeI-PTFE (into edumile ngegama layo lomkhiqizo, i-Teflon). Lezi zihlalo zakha uphawu olungangeni manzi ngokumelene nebhola. Isiqu sixhumanisa isibambo sangaphandle nebhola elingaphakathi. Uma uphendula isibambo ngama-degree angu-90, isiqu sijikeleza ibhola. Indawo yesibambo ihlala ikutshela ukuthi ivalvu ivuliwe noma ivaliwe. Uma isibambo sihambisana nepayipi, sivulekile. Uma siqondile, sivaliwe. Lo mklamo olula nosebenzayo unezingxenye ezimbalwa kakhulu ezihambayo, yingakho uthembeke kakhulu ezinhlotsheni eziningi emhlabeni jikelele.

Uyini umehluko phakathi kwama-valve e-L port nama-T port ball valve?

Iphrojekthi yakho idinga ukuthi uphambukise amanzi, hhayi nje ukuwamisa. Uhlela inethiwekhi eyinkimbinkimbi yamapayipi nama-valve, kodwa unomuzwa wokuthi kumelwe kube nesisombululo esilula nesisebenza kahle kakhulu.

Imbobo ye-L kanye nembobo ye-T zibhekisela esimweni sembobo ku-valve yebhola enezindlela ezintathu. Imbobo ye-L iphambukisa ukugeleza phakathi kwezindlela ezimbili, kuyilapho imbobo ye-T ingaphambukisa, ixube, noma ithumele ukugeleza ngqo.

Uma sikhuluma ngama-port e-L ne-T, sidlulela ngale kwama-valve alula okuvula/ukuvala bese singenaamavalvu anamachweba amaningiLezi zenzelwe ukuphatha indlela yokugeleza kwamanzi. Ziwusizo kakhulu futhi zingangena esikhundleni sama-valve amaningana ajwayelekile, zisindise isikhala nemali.

Amavalvu e-L-Port

Ivalvu ye-L-port inembobo efana no-“L.” Ine-inlet ephakathi nendawo kanye nezindawo ezimbili zokuphuma (noma izindawo ezimbili zokungena kanye nendawo eyodwa yokuphuma). Uma isibambo sisendaweni eyodwa, ukugeleza kusuka enkabeni kuye kwesobunxele. Ngokujika kwamadigri angu-90, ukugeleza kusuka enkabeni kuye kwesokudla. Indawo yesithathu ivimba konke ukugeleza. Ayikwazi ukuxhuma wonke ama-port amathathu ngesikhathi esisodwa. Umsebenzi wayo ukuphambukisa nje.

Amavalvu E-T-Port

A I-valve ye-T-portiguquguquka kakhulu. Imbobo yayo ibunjwe njengo-“T.” Ingenza konke okungenziwa yi-L-port. Kodwa-ke, inesikhundla esengeziwe sokubamba esivumela ukugeleza ngqo emachwebeni amabili aphikisanayo, njenge-valve yebhola ejwayelekile. Kwezinye izindawo, ingaxhuma wonke amachweba amathathu ngesikhathi esisodwa, okwenza kube kuhle kakhulu ukuxuba uketshezi olubili endaweni eyodwa.

Ingabe ama-valve epulaki agcwele imbobo?

Ubona olunye uhlobo lwevalvu yokujika kwekota ebizwa ngokuthi i-plug valve. Ibukeka njengevalvu yebhola, kodwa awuqiniseki ukuthi isebenza kanjani maqondana nokugeleza noma ukuthembeka kwesikhathi eside.

Njengama-valve ebhola, ama-valve epulagi angaba yi-port egcwele noma i-port encishisiwe. Kodwa-ke, ukwakheka kwawo kudala ukungqubuzana okwengeziwe, okwenza kube nzima ukuwajika futhi kube lula ukunamathela ngokuhamba kwesikhathi kune-valve yebhola.

Lokhu kuqhathanisa okuthakazelisayo ngoba kugqamisa ukuthi kunganiamavalvu ebholasezibe namandla kakhulu embonini.i-plug valveisebenzisa ipulaki eliyisilinda noma elicijile elinembobo kulo. Ivalvu yebhola isebenzisa imbulunga. Zombili zingaklanywa ngokuvuleka kwembobo egcwele, ngakho-ke ngaleyo ndlela, ziyafana. Umehluko oyinhloko usekusebenzeni kwazo. Ipulaki evalvu yepulaki inendawo enkulu kakhulu ebusweni exhumana njalo nomzimba wevalvu noma i-liner. Lokhu kudala ukungqubuzana okuningi, okusho ukuthi kudinga amandla engeziwe (i-torque) ukuze ijike. Lokhu kungqubuzana okuphezulu kwenza kube lula ukubamba uma ingasetshenziswa njalo. Ivalvu yebhola, ngakolunye uhlangothi, ivala ngezihlalo ezincane ze-PTFE eziqondiwe. Indawo yokuxhumana incane kakhulu, okuholela ekungqubuzaneni okuphansi nokusebenza okubushelelezi. Kwa-Pntek, sigxila ekwakhiweni kwevalvu yebhola ngoba inikeza ukuvala okuphezulu ngomzamo omncane kanye nokuthembeka okukhulu kwesikhathi eside.

Isiphetho

Akuwona wonke ama-valve ebhola e-PVC anezimbobo ezigcwele. Khetha njalo izimbobo ezigcwele zezinhlelo ezigeleza kakhulu kanye nezimbobo ezijwayelekile zokuvala okuvamile ukuze uthuthukise ukusebenza kanye nezindleko zezidingo zakho ezithile.
