I-Ball Valve vs. I-Gate Valve: Iyiphi Engcono Kakhulu Esicelweni Sakho?

Buka Isithombe Esikhulu
Kunamavalvu amaningi ezimboni atholakalayo emakethe.Izinhlobo ezahlukene zama-valve ezimbonini zisebenza ngendlela ehlukile.Abanye balawula ukuhamba kwemidiya kuyilapho abanye behlukanisa imidiya.Abanye balawula isiqondiso sabezindaba.Lezi futhi ziyahlukahluka ngomklamo kanye nosayizi.

Ama-valve amabili avame ukusetshenziswa ezimbonini ama-valve ebhola nama-valve esango.Zombili ziyaziwa ngokuhlinzeka ngezindlela zokuvala eziqinile.Lesi sihloko sizoqhathanisa ama-valve amabili ezintweni ezihlukahlukene njengezindlela zokusebenza, imiklamo, amachweba, nokunye okuthandwayo.

Iyini i-Ball Valve?

I-valve yebhola iyingxenye yomndeni we-valve yekota.Kuthatha kuphela ukujika okungu-90-degree ukuze ivuleke noma ivale.Idizayini ye-valve yebhola inebhola eligobile elisebenza njengediski elivumela ukuhamba kwemidiya.Ikakhulukazi kuma-non-slurry, ama-valve ebhola nawo afanelekele izinhlelo ezidinga ukuvala ngci.

Ukuvuleka nokuvala okusheshayo kwebhola kuyenza ibaluleke kwezinye izinhlelo zokusebenza ezidinga ukuhlukaniswa kwemidiya.Ama-valve ebhola avame ukusetshenziswa ezinhlelweni zokucindezela okuphansi.Kafushane, ama-valve ebhola angcono kakhulu ekulawuleni nasekulawuleni imidiya enokwehla kwengcindezi encane.

Iyini i-Gate Valve?

Ngakolunye uhlangothi, ama-valve esango ayingxenye yomndeni wama-valve ahambayo.Uma kungenjalo eyaziwa ngokuthi ivalvu yommese noma ivalve yesilayidi, ivalve yesango inediski eliyisicaba noma eliwuweji elisebenza njengesango.Leli sango noma i-disc ilawula ukugeleza koketshezi ngaphakathi kwe-valve.I-valve yesango isetshenziswa kangcono uma ukugeleza komugqa wemidiya enokwehla kwengcindezi encane kukhethwa.

Kuyi-valve evalayo enamandla okushaya ngamandla.Kuhloswe kakhulu ukugeleza kwezinto ezibonakalayo njengokulawulwa kokugeleza.Ifaneleka kakhulu imidiya yokugeleza eshubile, i-flat disc yamavalvu esango yenza kube lula ukunqamula uhlobo olunjalo lwemidiya.

I-valve yesango nayo iyingxenye yomndeni ojikelezayo njengoba isondo noma i-actuator idinga ukujikeleziswa ukuze i-wedge noma i-disc ivuleke.Ngendawo yalo yokuvala, isango liya phansi naphakathi kwezihlalo ezimbili ezitholakala engxenyeni engenhla yediski kanye nangaphansi njengoba kukhonjisiwe esithombeni esingenhla.

Isebenza Kanjani Ivalve Yebhola?

Amavalvu ebhola anendilinga engenalutho evumela ukudlula kwemidiya.Uma ubheka isigaba esiphambanayo se-valve yebhola ngezansi, ukusebenza kungokujikeleza kwe-shaft noma isiqu ngekota yokujika.Isiqu si-perpendicular engxenyeni yebhola ye-valve.

Uketshezi luvunyelwe ukuba ludlule lapho isiqu sikwi-engeli efanele ngokuqondene nediski yebhola.Ukunyakaza kwe-lateral kwabezindaba kudlala indima ebalulekile endleleni yokuvala.Amavalvu ebhola asebenzisa umfutho we-fluid ukuze asebenze phezu kwevalvu noma esihlalweni ukuze anikeze uphawu oluqinile, kuye ngokumiswa kwevalvu yebhola.

Ama-valve ebhola angaba imbobo egcwele noma imbobo encishisiwe.I-valve yebhola yembobo egcwele isho ukuthi ububanzi bayo buyafana nepayipi.Lokhu kuvumela i-torque ephansi yokusebenza kanye nokwehla kwengcindezi.Kodwa-ke, kukhona nohlobo oluncishisiwe lwembobo lapho ubukhulu be-valve buyisayizi eyodwa encane kunobukhulu bepayipi.

Isebenza kanjani i-Gate Valve?

Ama-valve esango asebenza ngokuphakamisa isango noma i-disc ukuvumela abezindaba ukuthi badlule ku-valve.Lezi zinhlobo zama-valve zivumela kuphela ukugeleza kwe-unidirectional kanye nokwehla kwengcindezi encane.Ubuvame ukubona amavalvu esango anamasondo ezandla.Isondo lesandla lihlanganiswe nokupakisha.

Kunezinhlobo ezimbili zemiklamo ye-valve stem yesango.Lapho leli sondo lesandla lijikeleza, isiqu sikhuphukela endaweni engaphandle futhi, ngesikhathi esifanayo, siphakamisa isango.Olunye uhlobo lwe-valve yesango i-valve yesango elingaphumi.Lokhu kubonakala ngesiqu esifakwe emkhawulweni, ngaleyo ndlela siveze kwabezindaba.

Lapho i-valve yesango ivuleka, indlela iba nkulu.Indlela yokugeleza ayiqondile ngomqondo wokuthi abezindaba bangakwazi ukuthatha isikhala njengoba kubonakala emfanekisweni ongezansi.Uma i-valve yesango isetshenziswa njenge-throttle, ingaba nesilinganiso sokugeleza esingalingani.Lokhu kuzodala ukudlidliza.Ukudlidliza okunjalo kungabangela umonakalo kudiski.

I-Valve Flow Direction

Amavalvu ebhola kanye namavalvu esango, ngokomthetho, ane-bi-directional.Lokhu kusho ukuthi ama-valve ebhola anamandla okuvimba imidiya kusukela ekupheleni komfula kanye nasekupheleni komfula.Bheka umfanekiso ongezansi.

Valve Seal Umthamo

Kumavalvu ebhola, izigxivizo zingalungiselelwa ukwakheka kwevalvu yebhola elintantayo futhi ingantanta kuvalvu yebhola efakwe ku-trunnion.Njengoba ama-valve ebhola evame ukusetshenziswa ezinhlelweni zokucindezela okuphansi, kucatshangelwa ubunjalo bendlela yokusebenza kwayo, izimpawu eziyinhloko zivame ukwenziwa nge-PTFE nezinye izinto ezihlobene.

Nakuba ukuvala okusheshayo nokuvulwa kwe-valve yebhola kungaba nenzuzo, lokhu kungabangela nezinkinga ezithile.Ama-valve ebhola athambekele kwisando samanzi noma ukuphakama okungazelelwe kwengcindezi lapho kuvalwa ivalvu.Lesi simo silimaza izihlalo ze-valve yebhola.

Ngaphezu kwalokho, isando samanzi singandisa ingcindezi ngaphakathi kwe-valve yebhola.Ezicelweni lapho izimo ezinjalo zingenzeka, okungukuthi impahla evuthayo, kunophawu lwesihlalo esiphuthumayo, ngokuvamile esakhiwe ngensimbi.Lesi isithiyo sesibili ezimeni lapho uphawu lwe-elastomeric lonakaliswa ezinsizeni zokucindezela okukhulu.Ukuze unciphise ukucindezela, ama-valve ebhola angaba nendawo yokucindezela efakwe.

Amavalvu esango anciphisa ukwehla komfutho lapho evulwe ngokugcwele.Lokhu kungenxa yokusetshenziswa kwe-design bore port design.Lokhu kusho ukuthi ubukhulu be-valve bulingana nobukhulu bepayipi.Kungenxa yalesi sici sama-valve esango abanika inzuzo ngaphezu kwama-valve ebhola.Ukushaywa kwamanzi akwenzeki kuma-valve esango.

I-downside ye-valve yesango ukuthi, umehluko wokucindezela okuphezulu uvame ukwenzeka lapho kuvaleka.Ukungqubuzana kungabangela ukuguga kwesihlalo nediski.

I-Valve Design kanye Nomehluko Wokwakha

Umehluko omkhulu phakathi kwama-valve ebhola nama-valve esango yisakhiwo sawo ngisho noma esebenza ngokufanayo.

Kuma-valve ebhola, ukunyakaza kwemidiya kugeleza mahhala.Ngaphandle kwalokhu, ukwakheka kwe-valve yebhola kuyivumela ukuthi ihlale isikhathi eside ngisho nangemva kokusetshenziswa kanzima.Yebo, umuntu kufanele acabangele nohlobo lwezinto ezisetshenziswayo ukuze azikhiqize.

Nakuba ama-valve ebhola enganikeli ukulawula okuhle, amandla awo okuvala okuqinile angenye yezinhlelo zokusebenza ezinomfutho ophansi.Ama-valve ebhola athembekile kulesi sici.Ukulahlekelwa kwengcindezi ephansi kungenye yekhwalithi yama-valve ebhola.Kodwa-ke, ngenxa yekhono lokujika kwekota lama-valve ebhola, kuthatha indawo eyengeziwe.

I-valve yesango, ngakolunye uhlangothi, isebenzisa isondo lesandla ukuvula noma ukuvala idiski.Umzimba we-valve nawo umncane kakhulu, ngakho-ke, kudingeka isikhala esincane kuphela.Ngokungafani nama-valve ebhola, ama-valve esango, anikeza isilawuli esicwengekile njengoba inamakhono okudonsa.Ingase ingabi nokuvala okusheshayo nekhono, kodwa ayikwazi ukulawula ukuhamba kwemidiya kuphela kodwa nokucindezela kwayo.
