1.0 Umehluko Phakathi Kwama-valve Esango le-OS&Y nama-valve Esango le-NRS

Okuvame ukubonakala kuma-valve esango yi-valve yesango lesiqu esikhuphukayo kanye ne-valve yesango lesiqu esingakhuphukiyo, ezifana ngandlela thile, okungukuthi:

(1) Amavalvu esango avala ngokuxhumana phakathi kwesihlalo sevalvu nediski yevalvu.

(2) Zombili izinhlobo zama-valve esango zinediski njengento yokuvula nokuvala, futhi ukunyakaza kwediski kuqonde ngqo ohlangothini loketshezi.

(3) Amavalvu esango angavulwa ngokugcwele noma avalwe ngokuphelele kuphela, futhi awakwazi ukusetshenziselwa ukulawula noma ukugoqa.

Ngakho-ke, umehluko phakathi kwazo uyini?I-TWSizochaza umehluko phakathi kwamavalvu esango lesiqu esikhuphukayo namavalvu esango lesiqu esingakhuphukiyo.

I-valve yesango le-OS&Y

Ukujikeleza isondo lesandla kuqhuba isiqu sevalvu enentambo phezulu noma phansi, kushukumise isango ukuze livule noma livale ivalvu.

I-Valve yeSango le-NRS

I-valve yesango le-Non-Rising Stem (NRS), eyaziwa nangokuthi i-valve yesango le-stem ejikelezayo noma i-valve yesango le-stem wedge engakhuphuki, ine-stem nut efakwe kwi-disc. Ukujikeleza isondo lesandla kuguqula i-valve stem, ephakamisa noma yehlisa i-disc. Ngokuvamile, intambo ye-trapezoidal ifakwa emshinini ekugcineni kwe-stem. Le ntambo, ehambisana nesiteshi sokuqondisa ku-disc, iguqula ukunyakaza kokujikeleza kube ukunyakaza okuqondile, ngaleyo ndlela iguqula i-torque yokusebenza ibe amandla okusunduza.

Ukuqhathaniswa kwama-NRS nama-OS&Y Gate Valve ekusetshenzisweni kwawo:

1. Ukubonakala Kwesiqu: Isiqu sevalvu yesango le-OS&Y sibonakala ngaphandle futhi siyabonakala, kanti esevalvu yesango le-NRS sivalelwe ngaphakathi komzimba wevalvu futhi asibonakali.
2. Indlela Yokusebenza: I-valve yesango le-OS&Y isebenza ngokusebenzisa ukuhlangana okunentambo phakathi kwesiqu kanye nesondo lesandla, okuphakamisa noma kwehlise i-stem kanye ne-disc assembly. Ku-valve ye-NRS, isondo lesandla liphendula isiqu, esijikeleza ngaphakathiidiski, futhi imicu yayo ihlangana ne-nut kudiski ukuze iyinyuse noma iye phansi.
3. Isibonakaliso Sendawo: Imicu yokushayela yevalvu yesango le-NRS ingaphakathi. Ngesikhathi sokusebenza, isiqu siyajikeleza kuphela, okwenza ukuqinisekiswa okubonakalayo kwesimo sevalvu kungenzeki. Ngokuphambene nalokho, imicu yevalvu yesango le-OS&Y ingaphandle, okuvumela ukuthi indawo yediski ibonwe ngokucacile nangokuqondile.
4. Isidingo Sesikhala: Amavalvu esango le-NRS anomklamo omncane kakhulu onokuphakama okungaguquki, adinga isikhala esincane sokufakwa. Amavalvu esango le-OS&Y anokuphakama okukhulu uma evuliwe ngokugcwele, okudinga isikhala esithe mpo.
5. Ukugcinwa Nokusetshenziswa: Isiqu sangaphandle sevalvu yesango le-OS&Y senza kube lula ukugcinwa kanye nokugcotshwa. Izintambo zangaphakathi zevalvu yesango le-NRS kunzima ukuzinakekela futhi zisengozini enkulu yokuguguleka kwemidiya eqondile, okwenza ivalvu ibe sengozini enkulu yokonakala. Ngenxa yalokho, amavalvu esango le-OS&Y anobubanzi bokusetshenziswa.

Imiklamo yesakhiwo se-valve yesango le-OS&Y kanye nama-valve esango le-NRS ihlukaniswe kanje:

1. I-valve yesango le-OS&Y:Isiqu se-valve nut sitholakala esembozweni se-valve noma esikhava. Uma uvula noma uvala idiski ye-valve, ukuphakamisa noma ukwehlisa isiqu se-valve kufezwa ngokujikeleza isiqu se-valve nut. Lesi sakhiwo siwusizo ekugcobeni isiqu se-valve futhi senza indawo yokuvula nokuvala ibonakale ngokucacile, yingakho sisetshenziswa kabanzi.
2. I-Valve yeSango le-NRS:I-nut yesiqu se-valve itholakala ngaphakathi komzimba we-valve futhi ixhumana ngqo ne-medium. Lapho uvula noma uvala i-valve disc, isiqu se-valve siyajikeleziswa ukuze kufezwe lokhu. Inzuzo yalesi sakhiwo ukuthi ukuphakama okuphelele kwe-valve yesango akushintshi, ngakho-ke kudinga isikhala esincane sokufaka, okwenza kufaneleke kuma-valve amakhulu noma ama-valve anesikhala esincane sokufaka. Lolu hlobo lwe-valve kufanele lufakwe isibonakaliso sokuvula/sokuvala ukukhombisa indawo ye-valve. Ububi balesi sakhiwo ukuthi izintambo zesiqu se-valve azikwazi ukugcotshwa futhi zivezwa ngqo ku-medium, okwenza zibe sengozini yokulimala.

Isiphetho

Kalula nje, izinzuzo zamavalvu esango lesiqu esikhuphukayo zisekulula ukuwabona, ukugcinwa okulula, kanye nokusebenza okuthembekile, okwenza avame kakhulu ekusetshenzisweni okuvamile. Ngakolunye uhlangothi, izinzuzo zamavalvu esango lesiqu esingakhuphukayo yisakhiwo sawo esincane kanye nomklamo wokonga isikhala, kodwa lokhu kuza ngezindleko zokuzwela kanye nokulula kokugcinwa, ngakho-ke avame ukusetshenziswa ezimweni ezinemikhawulo ethile yesikhala. Uma ukhetha, kufanele unqume ukuthi yiluphi uhlobo lwevalvu yesango ozolisebenzisa ngokusekelwe endaweni ethile yokufaka, izimo zokulungisa, kanye nendawo yokusebenza. Ngaphezu kwesikhundla sayo esiphambili emkhakheni wamavalvu esango, i-TWS iphinde yabonisa amakhono obuchwepheshe aqinile ezindaweni eziningi ezifanaamavalvu ebhabhathane, ama-valve okuhlola, futhiamavalvu okulinganisela. Singakusiza ukhethe uhlobo olufanele kakhulu lohlelo lwakho lokusebenza futhi samukele ithuba lokulwenza luhambisane nezidingo zakho eziqondile. Sizokunikeza incazelo eningiliziwe yomehluko phakathi kwama-valve esango le-stem elikhuphukayo kanye nelingakhuphuki esigabeni sethu esilandelayo. Hlala ubukele.
