Udinga ivalvu elula yokuvula/ukuvala umugqa wamanzi oyinhloko, kodwa izinketho zibonakala ziyinkimbinkimbi. Ukukhetha uhlobo olungalungile kungasho ukuthi awukwazi ukubona ukuthi ivuliwe noma ivaliwe, okuholela emaphutheni okusebenza.

Izinhlobo ezimbili eziyinhloko zamavalvu esango yisiqu esikhuphukayo kanye nesiqu esingavukiyo.ama-valve esiqu akhuphukayoIsibambo sihamba phezulu naphansi kanye nesango, sibonisa indawo yaso.isiqu esingavukiIsibambo sika-'s sijikeleza endaweni yaso kuphela.

Uma ngixoxa ngamaphrojekthi amanzi amakhulu nomlingani wami uBudi, isihloko sama-valve okuzihlukanisa ayinhloko sihlala sivela. Amakhasimende akhe e-Indonesia adinga izindlela ezithembekile zokuvala amanzi ukuze alungiswe ngaphandle kokuqagela. Ukukhetha phakathi kwesiqu esikhuphukayo ne-valve yesiqu engakhuphuki kuyisibonelo esiphelele sendlela umehluko omncane womklamo ongaba nomthelela omkhulu ngayo ekusebenzeni kwansuku zonke. Esinye sikunikeza uphawu olucacile olubonakalayo, kanti esinye sincane kakhulu. Ukuqonda lo mehluko oyisisekelo kuyisihluthulelo sokukhetha i-valve efanele yomsebenzi.

Yiziphi izinkinga zokusebenzisa ama-valve esango?

Ufake ivalvu yesango, kodwa manje udinga ukunciphisa ukugeleza, hhayi ukuyimisa. Ukuzama ukusebenzisa ivalvu yesango ngale njongo kungalimaza ivalvu ngokushesha futhi kubangele izinkinga epayipini lakho.

Amavalvu esango awakwazi kahle ukugeleza kwe-throttling. Angadlidliza futhi abangele ukuguguleka kwesihlalo kanye nediski uma evuliwe kancane. Abuye asebenze kancane futhi angaba sengozini yokubhajwa ngenxa yokwakheka kwenhlabathi.

Amavalvu esango aklanyelwe umsebenzi owodwa: ukuvuleka ngokuphelele noma ukuvalwa ngokuphelele. Asebenza kahle kakhulu kulokhu. Umaivalvu yesangoivuliwe ngokuphelele, “isango” lingaphandle ngokuphelele kwendlela yokugeleza, ngakho cishe akukhoukwehla kwengcindezi. Kodwa ngesikhathi uzama ukuyisebenzisa ukulawula ukugeleza ngokuyishiya ivulekile kancane, izinkinga ziyaqala. Amanzi ashesha kakhulu ageleza ngembobo encane adala ukuxokozela okukhulu. Lokhu kuxokozela kubangela ukuthi isango lidlidlize futhi liqhume esihlalweni salo. Ngokuhamba kwesikhathi, lokhu kukhukhuleka kuzolimaza unomphela izindawo zokuvala zesango kanye nomzimba. Uma ekugcineni uzama ukulivala ngokuphelele, ngeke lisakha isivalo esiphelele futhi lizovuza. Futhi lihamba kancane kakhulu. Ivalvu enkulu yesango ingathatha amashumi noma amakhulu amajika esibambo ukusuka ekuvulekeni ngokuphelele kuya ekuvalekeni ngokuphelele.

Izinkinga Eziyinhloko Zama-Gate Valve

Ububi	Kungani Kwenzeka	Umphumela
Ukubhoboza Okubi	Isango liyanyakaza kancane kancane.	Ukuguga okusheshayo kwesango nesihlalo.
Ukusebenza Okuhamba Kancane	Kudinga ukujika okuningi kwesondo lesandla.	Akufanelekile ukuvala okuphuthumayo.
Kuthambekele ekuqhumeni	Udaka lunganqwabelana emgodini ongezansi.	Ivalvu ingase ingavaleki ngokuphelele.
Ukungaqiniseki Kwesikhundla	Kunzima ukubona ukuthi i-stem valve engavuki ivuliwe noma ivaliwe.	Kungenzeka kube namaphutha okusebenza.

Ngingayisebenzisa yini ivalvu yesihlalo se-PVC?

Udinga ukusebenzisa umugqa wamanzi we-PVC okhona kakade ukuze uthole uxhumano oluncane. Ivalvu yesihlalo ibonakala iyisisombululo esisheshayo nesilula, kodwa ukhathazekile ukuthi ingase yonakalise ipayipi lepulasitiki.

Cha, akufanele neze usebenzise indinganisoivalvu yesihlalokumapayipi e-PVC. Amavalvu esihlalo asebenza ngokubhoboza ipayipi, okuzokwenza i-PVC iqhekeke futhi yehluleke, okuholela ekuvuzeni okukhulu.

Leli iphuzu elibalulekile lokuphepha engihlala ngigcizelela kuBudi. Ama-valve e-saddle aklanyelwe amapayipi ensimbi aqinile njengethusi. Anephini elibukhali oligoqa phansi ukuze ubhoboze udonga lwepayipi ukuze udale impompi yamanzi. Le ndlela iyinhlekelele ku-PVC. I-PVC inamandla, kodwa futhi iyinto ezwela ukuqhekeka. Lokhu kusho ukuthi uma udala iphuzu elibukhali lokucindezeleka, njengembobo evela ephini elibhobozayo, umfantu ungaqala kalula futhi uhambe odongeni lwepayipi. Ukucindezela okuqhubekayo kwamanzi kuzosebenzisa leli phuzu elibuthakathaka. Kungase kungavuzi ngokushesha, kodwa ngokuhamba kwesikhathi, ngokushintsha kwengcindezi kanye nokushisa, leyo mbobo encane izoba umfantu omkhulu futhi ipayipi lizoqhuma. Indlela efanele yokuthinta umugqa we-PVC ukusebenzisa "i-t-shirt yesihlalo"noma" umkhono wokuthinta." Lezi zinto zinamathela noma zibopha ipayipi, bese usebenzisa i-drill ukudala imbobo ehlanzekile, enikeza uxhumano oluphephile, olungavuzi ngaphandle kokuphazamisa isakhiwo sepayipi.

Iyiphi ivalvu yesango evame kakhulu futhi esetshenziswa kabanzi?

Udinga ukugcina uhlobo oluvame kakhulu lwe-valve yesango lokusabalalisa amanzi ajwayelekile. Ufuna ukunikeza leyo amakhasimende akho azoyicela njalo ukuze kube lula ukuqoqwa kwempahla yakho.

Uhlobo oluvame kakhulu nolusetshenziswa kabanzi yi-isiqu esingavuki (i-NRS), i-wedge eqinile,ivalvu yesango ehlala iqinile. Iyathandwa ngenxa yokwakheka kwayo okuncane, ukuqina kwayo, kanye nokufaneleka kwayo emisebenzini yamanzi engaphansi komhlaba kanye namapayipi ajwayelekile.

Lolu hlobo oluthile luyi-servitor yemboni yamanzi, futhi yi-valve amaklayenti kaBudi ajwayelene nayo kakhulu. Ake sichaze ukuthi kungani ithandwa kangaka. I-"Non-ringing stem" isho ukuthi incane kakhulu, efanelekile ukufakwa ezindaweni eziqinile noma egqitshwe ngaphansi komhlaba, njengoba ungadingi indawo eyengeziwe ukuze i-stem ihambe iye phezulu naphansi. I-"Solid wedge" ibhekisela esangweni elilula, eliqinile, elinengxenye eyodwa ngaphakathi, elithembekile futhi elingabizi kakhulu. Ingxenye ebaluleke kakhulu "ihlala phansi." Lokhu kusho ukuthi isango lensimbi limbozwe ngerabha (njenge-EPDM). Lapho i-valve ivala, le wedge yerabha icindezela emzimbeni wangaphakathi obushelelezi we-valve, idale uphawu oluqinile njenge-bubble. Lo mklamo ungcono kakhulu ekuvaleni kunezihlalo ezindala zensimbi kuya kwensimbi futhi uvimbela indle ukuthi ibambeke phansi, okuqinisekisa uphawu olungcono lwesikhathi eside. Yilokhu kuhlanganiswa komklamo oqinile, othembekile, nongavuzi okwenze kwaba yindinganiso yomhlaba wonke yezindawo zamanzi.

Yiziphi ezinye izindlela zokufaka esikhundleni se-valve yesango?

Udinga ivalvu yokuvula/yokuvala, kodwa ivalvu yesango ibonakala ihamba kancane noma ayilungele ukusetshenziswa. Udinga ukwazi ukuthi yiziphi ezinye izinketho ezitholakalayo ukuze wenze ukukhetha okungcono kakhulu.

Izindlela ezimbili eziyinhloko zokushintsha ama-valve esango ama-ball valve nama-butterfly valve. Ama-ball valve amahle kakhulu ekuvalekeni okusheshayo, okujika ngekota emapayipini amancane. Ama-butterfly valve ayisinqumo esingabizi kakhulu samapayipi amakhulu.

Ukukhetha phakathi kwala ma-valve kuncike ngokuphelele emsebenzini.ivalvu yebholaYisincomo sami engisithandayo kunoma yiliphi ipayipi elingaba ngu-4 inches ububanzi. Lisebenzisa ibhola lensimbi elinembobo kulo. Ukujika okulula kwesibambo ngamadigri angu-90 kuqondanisa imbobo nepayipi ukuze kugeleze ngokugcwele noma kuliphendule ngokumelene nokugeleza ukuze limiswe ngokuphelele. Lokhu kwenza lisebenze ngokushesha okukhulu, futhi ungabona indawo yalo ngokubheka isibambo. Liphinde libe ngcono kakhulu ekubhodleni ukugeleza kunevalvu yesango. Kumapayipi amakhulu kakhulu, njengepayipi lamanzi elingamasentimitha angu-12, ivalvu yesango iba nkulu futhi ibize kakhulu. Yilaphoivalvu yebhabhathaneiphelele. Isebenzisa idiski elincane phakathi kwepayipi elijikeleza ama-degree angu-90 ukuvula noma ukuvala. Zilula, zincane, futhi zingabizi kakhulu kunevalvu enkulu yesango, okwenza zibe ukukhetha okujwayelekile kwezindawo zamanzi ezinkulu nezitshalo zezimboni.

I-Gate Valve vs. Ezinye Izindlela

Uhlobo lwe-Valve	Okuhle Kakhulu Kwaba	Ochwepheshe	Ububi
I-Valve yeSango	Ukuhlukaniswa okuvulekile/okuvaliwe ngokuphelele	Ukugeleza okungavinjelwe, ukuvala okuhle	Kuhamba kancane, kubi ekucindezeleni
I-Ball Valve	Ukuvala okusheshayo, amapayipi amancane	Kuyashesha, kuthembekile, kuhle ukubhoboza	Kubiza kakhulu, ukwehla kwengcindezi okuphezulu
I-Butterfly Valve	Amapayipi amakhulu	Ilula, intengo ephansi, iyashesha	Idiski ihlala isebenza

Isiphetho

Amavalvu esangoziza njengezinhlobo zesiqu ezikhulayo noma ezingakhuphuki, zilungele ukulawula okulula kokuvula/ukuvala. Ngezinye izidingo,ibholafuthiamavalvu ebhabhathaneinikeza ukusebenza okusheshayo kanye nokusebenza okungcono kosayizi abahlukene bamapayipi.
