Izindaba - Yiziphi izinhlobo ezine zamavalvu ebhola?

Ukukhetha ivalvu yebhola kubonakala kulula uze ubone zonke izinketho. Khetha okungalungile, futhi ungase ubhekane nokugeleza okulinganiselwe, ukulawula okubi, noma ngisho nokwehluleka kwesistimu.

Izinhlobo ezine eziyinhloko zamavalvu ebhola zihlukaniswa ngemisebenzi kanye nomklamo wazo: ivalvu yebhola entantayo, ivalvu yebhola efakwe ku-trunnion, ivalvu egcwele imbobo, kanye nevalvu yembobo encishisiwe. Ngayinye ifanelekela ukucindezela okuhlukile kanye nezidingo zokugeleza.

Izinhlobonhlobo zezinhlobo ezahlukene zamavalvu ebhola, kufaka phakathi ama-floating, trunnion, kanye nosayizi abahlukene be-port

Ngivame ukukhuluma noBudi, umphathi wokuthenga komunye wabalingani bethu e-Indonesia, mayelana nokuqeqesha ithimba lakhe lokuthengisa. Esinye sezithiyo ezinkulu kubathengisi abasha ukuhlukahluka okukhulu kwama-valve. Bayaqonda umsebenzi oyisisekelo wokuvula/ukuvala, kodwa-ke bashaywa ngamagama anjengokuthi “i-trunnion^[1],” “I-L-port,” noma “ukuntanta^[2].” Ikhasimende lingase licele ivalvu yomugqa wokucindezela okuphezulu, futhi umthengisi omusha angase anikeze ivalvu ejwayelekile entantayo lapho ivalvu ye-trunnion iyiyona edingekayo ngempela. Ukuhlukanisa lezi zigaba zibe imiqondo elula neqondakalayo kubalulekile. Akukhona nje ukuthengisa umkhiqizo; kumayelana nokunikeza ikhambi elifanele ukuze iphrojekthi yekhasimende iphumelele.

Yiziphi izinhlobo ezine zamavalvu ebhola?

Udinga i-valve, kodwa ikhathalogi ikhombisa izinhlobo eziningi. Ukusebenzisa engalungile kungadala isithiyo ohlelweni lwakho noma kusho ukuthi ukhokha ngokweqile ngezici ongazidingi ngisho.

Ama-valve ebhola avame ukuhlukaniswa ngokwesakhiwo sawo sebhola kanye nosayizi webhore. Izinhlobo ezine ezivamile yilezi: ezintantayo nezifakwe ema-trunnion (ngokusekelwa kwebhola) kanye ne-full-port kanye ne-reduced-port (ngosayizi wokuvula). Ngayinye inikeza ibhalansi ehlukile yokusebenza kanye nezindleko.

Umbono oqondile oqhathanisa imiklamo yevalvu entantayo, e-trunnion, egcwele imbobo, kanye neye-reduced-port valve

Ake sichaze lokhu kalula. Izinhlobo ezimbili zokuqala zimayelana nendlela ibhola elisekelwa ngayo ngaphakathi kwevalvu.ivalvu yebhola elintantayo^[3]uhlobo oluvame kakhulu; ibhola libanjwe yizihlalo ezingezansi kanye nezingenhla komfula. Lihle kakhulu ezinhlelweni eziningi ezijwayelekile.ivalvu efakwe ku-trunnion^[4]inezisekeli ezengeziwe zemishini—isiqu phezulu kanye nesiqu phansi—esibamba ibhola. Lokhu kuyenza ifaneleke kakhulu kuma-valve anomfutho ophezulu noma amakhulu kakhulu. Izinhlobo ezimbili ezilandelayo zilingana nosayizi wembobo ebholeni.imbobo egcweleivalvu (noma egcwele imbobo) inomgodi olingana nowepayipi, okubangela ukuvinjelwa kokugeleza kwamanzi.imbobo encishisiweivalvu inembobo encane. Lokhu kulungile ezimweni eziningi futhi kwenza ivalvu ibe ncane futhi ithengeke kalula.

Ukuqhathanisa Izinhlobo Ezine Eziyinhloko

Uhlobo lwe-Valve	Incazelo	Okuhle Kakhulu Kwaba
Ibhola Elintantayo	Ibhola libanjwa ngokucindezelwa phakathi kwezihlalo ezimbili.	Ukusetshenziswa okujwayelekile, okuphansi kuya kokuphakathi kwengcindezi.
I-Trunnion Efakwe	Ibhola lisekelwa yisiqu esiphezulu kanye nesinqe esingezansi.	Insizakalo ecindezela kakhulu, enobubanzi obukhulu, nebalulekile.

Wazi kanjani ukuthi i-ball valve ivuliwe noma ivaliwe?

Usuzosika ipayipi, kodwa uyaqiniseka ukuthi ivalvu ivaliwe? Iphutha elilula lapha lingaholela ekuphazanyisweni okukhulu, ekulimaleni kwamanzi, noma ngisho ekulimaleni.

Ungabona ukuthiivalvu yebholaivuliwe noma ivaliwe ngokubheka indawo yesibambo maqondana nepayipi. Uma isibambo sihambisana nepayipi, ivalvu ivulekile. Uma isibambo siqondile (sakha isimo "sika-T"), ivalvu ivaliwe.

Isithombe esicacile esibonisa isibambo se-ball valve esihambisana nepayipi (evulekile) kanye nesinye esiqondile (esivaliwe)

Lolu ulwazi oluyisisekelo nolubaluleke kakhulu kunoma ubani osebenza ngama-ball valve. Indawo yesibambo iyisibonakaliso esiqondile sendawo yebhola. Lesi sici sokuklama esilula singenye yezizathu eziyinhloko ezenza ama-ball valve athandwe kangaka. Akukho ukuqagela. Ngake ngezwa indaba evela kuBudi mayelana nesisebenzi esincane sokulungisa esikhungweni esasiphuthuma. Wabheka i-valve wacabanga ukuthi icishiwe, kodwa kwakuyi-valve yesango endala eyayidinga ukujika kaningi, futhi wayengenakukwazi ukubona isimo sayo ngokubona. Wenza ukusika futhi wagcwalisa igumbi. Nge-ball valve, lelo phutha cishe akunakwenzeka ukulenza. Isenzo sokujika kwekota kanye nendawo yesibambo ecacile kunikeza impendulo esheshayo nengacacile: emgqeni "kuvuliwe," ngaphesheya "kuvaliwe." Lesi sici esilula siyithuluzi lokuphepha elinamandla.

Uyini umehluko phakathi kwama-valve ebhola ohlobo lwe-T nohlobo lwe-L?

Udinga ukuguqula ukugeleza kwamanzi, hhayi ukumane ukumise. Uku-oda i-valve ejwayelekile ngeke kusebenze, futhi uku-oda i-valve enamachweba amaningi okungalungile kungathumela amanzi endaweni engafanele nhlobo.

Uhlobo lwe-T kanye nohlobo lwe-L zibhekisela esimweni sembobo ebholeni levalvu enezindlela ezintathu. Uhlobo lwe-L lungaphambukisa ukugeleza kusuka endaweni eyodwa yokungena kuya kwenye yezindawo ezimbili zokuphuma. Uhlobo lwe-T lungenza okufanayo, futhi lungaxhumanisa wonke amachweba amathathu ndawonye.

Imidwebo ekhombisa izindlela zokugeleza kwamavalvu ebhola angu-L-Type kanye no-T-Type angu-3-way

Leli iphuzu elivamile lokudideka kubantu abathenga ivalvu yabo yokuqala enezindlela ezintathu. Ake sicabange ngevalvu enezimbobo ezintathu: phansi, kwesobunxele, nakwesokudla.I-L-Port^[5]Ivalvu inomgodi ogobile ngamadigri angu-90 obhobozwe ebholeni. Endaweni eyodwa, ixhuma imbobo engezansi nembobo engakwesokunxele. Ngokujika kwekota, ixhuma imbobo engezansi nembobo engakwesokudla. Ayikwazi ukuxhumanisa konke okuthathu. Iphelele ekudluliseni ukugeleza kusuka emthonjeni owodwa kuya ezindaweni ezimbili ezihlukene. AI-T-Port^[6]Ivalvu inesimo "sika-T" esibhobozwe ebholeni. Inezinketho eziningi. Ingaxhuma phansi ngakwesobunxele, phansi ngakwesokudla, noma ingaxhuma kwesobunxele ngakwesokudla (idlula phansi). Okubaluleke kakhulu, futhi inesikhundla esixhumanisa wonke amachweba amathathu ngesikhathi esisodwa, okuvumela ukuxuba noma ukuphambukisa. Ithimba likaBudi lihlala libuza ikhasimende: “Ingabe udinga ukuxuba ukugeleza, noma umane ushintshe phakathi kwawo?” Impendulo ibatshela ngokushesha ukuthi kudingeka i-T-Port noma i-L-Port.

Amakhono e-L-Port vs. T-Port

Isici	I-valve ye-L-Port	I-T-Port Valve
Umsebenzi Oyinhloko	Ukuphambukisa	Ukuphambukisa noma Ukuxuba
Xhuma Zonke Izimbobo Ezintathu?	No	Yebo
Isikhundla Sokuvala?	Yebo	Cha (Ngokuvamile, ichweba elilodwa lihlala livuliwe)
Ukusetshenziswa Okuvamile	Ukushintsha ukugeleza phakathi kwamathangi amabili.	Ukuxuba amanzi ashisayo nabandayo, gwema imigqa.

Uyini umehluko phakathi kwe-trunnion ne-floating ball valve?

Uhlelo lwakho lusebenza ngaphansi komfutho ophezulu. Uma ukhetha i-valve yebhola ejwayelekile, umfutho ungenza kube nzima ukuyijika noma ubangele ukuthi izivalo zihluleke ngokuhamba kwesikhathi.

Kuvalvu entantayo, ibhola "liyantanta" phakathi kwezihlalo, licindezelwa yingcindezi. Kuvalvu ye-trunnion, ibhola liqiniswa ngomshini yi-shaft ephezulu nephansi (i-trunnion), emunca ingcindezi futhi inciphise ukucindezeleka ezihlalweni.

Imidwebo yokusika eqhathanisa indlela yangaphakathi yevalvu yebhola entantayo kanye nevalvu yebhola efakwe ku-trunnion

Umehluko umayelana nokuphatha amandla. Ngokwezingaivalvu yebhola elintantayo^[7], lapho ivalvu ivaliwe, ingcindezi ephezulu isunduza ibhola kanzima esihlalweni esingezansi. La mandla adala uphawu. Nakuba isebenza kahle, lokhu kudala nokungqubuzana okuningi, okungenza kube nzima ukuyijika ivalvu, ikakhulukazi ngobukhulu obukhulu noma ngaphansi kwengcindezi ephezulu.ivalvu efakwe ku-trunnion^[8]ixazulula le nkinga. Ibhola liqiniswe endaweni yalo yizisekeli ze-trunnion, ngakho-ke alicindezelwa ukugeleza. Esikhundleni salokho, ingcindezi isunduza izihlalo ezigcwele intwasahlobo ngokumelene nebhola elingashukumi. Lo mklamo umunca amandla amakhulu, okuholela ekutheni i-torque ephansi kakhulu (kulula ukuyijika) kanye nokuphila isikhathi eside kwesihlalo. Yingakho ukusetshenziswa kwezimboni okunomfutho ophezulu, ikakhulukazi embonini kawoyela negesi, ama-trunnion valve kuyindinganiso edingekayo. Ezinhlelweni eziningi ze-PVC, ingcindezi iphansi ngokwanele ukuthi i-valve entantayo isebenza kahle.

Ukuntanta vs. I-Trunnion Ikhanda Liya Ekhanda
