1.0 Umehluko Phakathi Kwamavalvu Esango Le-OS&Y kanye Namavalvu Esango Le-NRS

Okuvame ukubonakala kuma-valve esango i-valve yesango ye-stem ekhuphukayo kanye ne-valve yesango ye-stem engakhuphuki, abelana ngokufana okuthile, okungukuthi:

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

(2) Zombili izinhlobo ze-valve zesango zine-disc njengesici sokuvula nokuvala, futhi ukunyakaza kwe-disc ku-perpendicular ekuqondeni koketshezi.

(3) Amavalvu esango angavulwa ngokugcwele noma avalwe ngokuphelele, futhi angeke asetshenziselwe ukulawula noma ukudonsa.

Ngakho, yimuphi umehluko phakathi kwabo?I-TWSizochaza umehluko phakathi kwamavalvu esango lesiqu akhuphukayo kanye namavalvu esango lesiqu angaphumi.

I-OS&Y Gate Valve

Ukuzungezisa isondo lesandla kushayela isiqu se-valve enentambo phezulu noma phansi, ukuhambisa isango ukuze livule noma livale ivalvu.

I-NRS Gate Valve

Ivalvu yesango ye-Non-Rising Stem (NRS), eyaziwa nangokuthi i-valve yesango lesiqu esizungezayo noma i-valve yesango le-stem wedge engaphumi, ifaka inadi le-stem eligxunyekwe kudiski. Ukuzungezisa isondo lesandla kuguqula isiqu se-valve, ephakamisa noma ehlise idiski. Ngokuvamile, intambo ye-trapezoidal yenziwa ngomshini ekugcineni okuphansi kwesiqu. Lolu chungechunge, olusebenzisana nesiteshi somhlahlandlela kudiski, luguqula ukunyakaza okujikelezayo kube ukunyakaza okulandelanayo, ngaleyo ndlela kuguqule i-torque yokusebenza ibe amandla okucindezela.

Ukuqhathaniswa kwe-NRS kanye ne-OS&Y Gate Valves ekufakeni isicelo:

1. Ukubonakala Kwesiqu: Isiqu se-valve yesango le-OS&Y sivezwa ngaphandle futhi siyabonakala, kuyilapho leso valvu yesango le-NRS sivalelwe ngaphakathi komzimba wevalvu futhi singabonakali.
2. Indlela Esebenzayo: Ivalvu yesango ye-OS&Y isebenza ngokuhlanganyela okunentambo phakathi kwesiqu nesondo lesandla, eliphakamisa noma lehlise isiqu nediski. Kuvalvu ye-NRS, isondo lesandla liphendula isiqu, esizungeza phakathiidiski, futhi imicu yayo isebenzisana nenadi kudiski ukuyihambisa phezulu noma phansi.
3. Inkomba Yesikhundla: Imicu yokushayela ye-valve yesango le-NRS ingaphakathi. Ngesikhathi sokusebenza, isiqu sijikeleza kuphela, okwenza ukuqinisekiswa okubonakalayo kwesimo se-valve kungenzeki. Ngokuphambene, imicu yevalvu yesango ye-OS&Y ingaphandle, okuvumela indawo yediski ukuthi ibonwe ngokucacile nangokuqondile.
4. Isidingo Sesikhala: Amavalvu esango le-NRS anomklamo ohlangene nobude obungaguquki, adinga indawo encane yokufaka. Amavalvu esango le-OS&Y anobude obuphelele uma evuleke ngokugcwele, okudinga isikhala esime ngaphezulu.
5. Ukugcinwa Nokusebenza: Isiqu sangaphandle se-valve yesango le-OS&Y sisiza ukugcinwa nokugcotshwa kalula. Izintambo zangaphakathi ze-valve yesango le-NRS zinzima kakhulu ukusevisa futhi zisengozini yokuguguleka kwemidiya eqondile, okwenza i-valve ibe lula ekulimaleni. Ngakho-ke, ama-valve esango le-OS&Y anobubanzi obubanzi bokusebenza.

Imiklamo yesakhiwo ye-OS&Y i-valve yesango kanye nama-valve esango le-NRS ahlukaniswe ngale ndlela elandelayo:

1. I-OS&Y Gate Valve:I-valve stem nut itholakala kukhava ye-valve noma ubakaki. Lapho uvula noma uvala i-disc ye-valve, ukuphakamisa noma ukwehlisa i-valve stem kufinyelelwa ngokuzungeza i-valve stem nut. Lesi sakhiwo sinenzuzo yokugcoba isiqu se-valve futhi senza indawo yokuvula nokuvala ibonakale ngokucacile, yingakho isetshenziswa kabanzi.
2. I-NRS Gate Valve:I-valve stem nut itholakala ngaphakathi komzimba we-valve futhi ithintana ngokuqondile nendawo. Lapho uvula noma uvala i-disc ye-valve, isiqu se-valve siyazungezwa ukuze kuzuzwe lokhu. Inzuzo yalesi sakhiwo ukuthi ukuphakama okuphelele kwe-valve yesango kuhlala kungashintshiwe, ngakho-ke kudinga indawo encane yokufaka, okwenza kube kuhle kuma-valve amakhulu noma ama-valve anendawo elinganiselwe yokufaka. Lolu hlobo lwe-valve kufanele lufakwe inkomba evulekile / evaliwe ukukhombisa indawo ye-valve. Ukungalungi kwalesi sakhiwo ukuthi izintambo ze-valve stem azikwazi ukugcotshwa futhi zivezwe ngokuqondile phakathi nendawo, okwenza kube lula ukulimala.

Isiphetho

Kalula nje, izinzuzo zokukhuphuka kwama-valve esango le-stem zilele ekubukeni kwawo kalula, ukunakekelwa okufanele, nokusebenza okuthembekile, okuwenza avame kakhulu ekusebenzeni okujwayelekile. Ngakolunye uhlangothi, izinzuzo zama-valve amasango e-stem angakhuphuki yisakhiwo sawo esihlangene kanye nomklamo wokulondoloza isikhala, kodwa lokhu kuza ngezindleko zokuqonda kanye nokulula kokugcinwa, ngakho-ke zivame ukusetshenziswa ezimweni ezinezingqinamba ezithile zesikhala. Lapho ukhetha, kufanele unqume ukuthi yiluphi uhlobo lwe-valve yesango ozoyisebenzisa ngokusekelwe endaweni ethile yokufaka, izimo zokugcinwa, kanye nendawo yokusebenza. Ngaphezu kwesikhundla sayo esihamba phambili emkhakheni wamavalvu esango, i-TWS iphinde yakhombisa amakhono aqinile ezobuchwepheshe ezindaweni eziningi njengeizivalo uvemvane, hlola ama-valve, futhiama-valve okulinganisa. Singakusiza ukuthi ukhethe uhlobo olufanele lohlelo lwakho lokusebenza futhi samukele ithuba lokulwenza luhambisane nezidingo zakho ngqo. Sizohlinzeka ngencazelo eningiliziwe yomehluko phakathi kwamavalvu esango lesiqu esikhuphukayo kanye nalawo angakhuphuki esigabeni sethu esilandelayo. Hlala ubukele.
