1.0 Umehluko Emkhatsini Wemavalvu Esango Le-OS&Y Nemavalvu Esango Le-NRS

Lokuvame kubonakala kumavalvu esango yi valve yesango lekhuphukako kanye ne valve yesango lelingakhuphuki, lehlanganyela lokunye lokufanako, lokungu:

(1) Emavalvu esango avala ngekutsintsana emkhatsini wesihlalo sevalvu kanye ne-disc yevalve.

(2) Totimbili tinhlobo temavalvu esango tine-disc njengentfo levulako nalevalako, futsi kuhamba kwale-disc kuhambisana nendlela lehamba ngayo le-fluid.

(3) Emavalvu esango angavulwa ngalokuphelele noma avalwe ngalokuphelele kuphela, futsi angeke asetjentiselwe kulawula noma kucindzetela.

Ngako-ke, ngumuphi umehluko emkhatsini wabo?TWSitawuchaza umehluko emkhatsini wemavalvu esango lesicu lekhuphukako kanye nemavalvu esango lesicu lelingakhuphuki.

Ivalvi yeLisango le-OS&Y

Kujikeleta lelisondvo lesandla kuhamba sicu se valve lenetintsambo etulu noma phansi, kuhambisa lisango kutsi livule noma livale le valve.

Ivalvi yeLisango le-NRS

Le valve yesango le Non-Rising Stem (NRS), lephindze yatiwe ngekutsi yi valve yesango lesicu lejikeletako noma ivalve yesango le wedge yesicu lesingakhuphuki, ifaka nati yesicu lefakwe kuleli diski. Kujikeleta lisondvo lesandla kujika sicu sevalve, lesiphakamisa noma sehlisa le disc. Ngalokuvamile, intambo ye trapezoidal yentiwa ngemshini ekugcineni lokuphansi kwesicu. Le thread, lehlanganyela nesiteshi sekucondzisa kule disc, igucula kunyakata lokujikeletako kube kunyakata lokusemgceni, ngaleyo ndlela igucula i-torque lesebentako ibe ngemandla ekucindzetela.

Kucatsanisa kwe-NRS kanye ne-OS&Y Gate Valves ekusebentiseni:

1. Kubonakala Kwesicu: Sicu se valve yesango le OS&Y sivulekile ngaphandle futsi siyabonakala, kantsi leso se valve yesango le NRS sivaliwe ngaphakatsi kwemtimba we valve futsi asibonakali.
2. Indlela Yekusebenta: Ivalve yesango le OS&Y isebenta ngekuhlangana lokunetintsambo emkhatsini wesicu kanye nelisondvo lesandla, lokuphakamisa noma kwehlisa sicu kanye nekuhlanganiswa kwe disc. Ku-valve ye-NRS, isondo lesandla lijika sicu, lesijikeleta ku- .idiski, futsi imicu yayo ihlangana ne-nut kule- disc kute iyihambise etulu nobe phansi.
3. Inkomba Yesikhundla: Imicu yekushayela ye-valve yesango le-NRS ingekhatsi. Ngesikhatsi sekusebenta, lesicu sijikeleta kuphela, kwenta kucinisekiswa lokubonwako kwesimo sevalve kungenteki. Ngalokwehlukile, imicu ye-OS&Y gate valve ingaphandle, kuvumela indzawo ye-disc kutsi ibonakale ngalokucacile futsi ngalokucondzile.
4. Sidzingo Sendzawo: Emavalvu esango le-NRS anesakhiwo lesincane kakhulu ngekuphakama lokungagucuki, kudzinga indzawo lencane yekufaka. Emavalvu esango le OS&Y anebudze lobukhulu jikelele uma avulekile ngalokuphelele, kudzinga sikhala lesiningi lesimile.
5. Kugcinwa & Kusebentisa: Sicu sangaphandle se-OS&Y gate valve senta kutsi kube lula kugcinwa kanye nekugcobisa. Imicu lengekhatsi ye valve yesango le NRS kumatima kuyisebenta futsi itsatseka kalula ngekuguguleka kwetindzaba leticondzile, kwenta le valve ibe nekulimala. Ngenca yaloko, OS & Y isango valves babe uhla ebanzi isicelo.

Lemiklamo yesakhiwo se-OS&Y gate valve kanye ne-NRS gate valve ihlukaniswe ngalendlela lelandzelako:

1. Ivalvi yeLisango le-OS&Y:I-nut yesicu sevalve isesimbonyweni sevalve noma kubakaki. Uma kuvulwa noma kuvalwa idiski yevalve, kuphakamisa noma kwehlisa sicu sevalve kufezwa ngekujikeleta nut yesicu sevalve. Lesakhiwo siyazuzisa ekugcobeni sicu se valve futsi senta indzawo yekuvula nekuvala ibonakale kahle, kungako isetjentiswa kakhulu.
2. Ivalvi yeLisango le-NRS:I-valve stem nut isekhatsi emtimbeni wevalve futsi itsintsana ngco ne-medium. Uma kuvulwa noma kuvalwa idiski yevalve, sicu sevalve siyajikeletwa kwentela kufeza loku. Inzuzo yalesakhiwo kutsi kuphakama konkhe kwevalve yesango kuhlala kungashintji, ngako-ke kudzinga indzawo lencane yekufaka, kwenta kutsi ilungele emavalvu lamakhulu-diameter noma emavalvu lanesikhala lesincane sekufaka. Loluhlobo lwe valve kumele lufakwe inkomba levulekile/levaliwe kukhombisa indzawo ye valve. Lokungakalungi kwalesi sakhiwo kutsi imicu yesicu sevalve ayikhoni kugcotjwa futsi ivulekele ngco kulendzawo lesemkhatsini, kwenta kutsi ibe nekulimala.

Siphetfo

Ngamafuphi, tinzuzo tekukhuphuka kwemavalvu esango lesicu tilele ekubukeni kwawo kalula, kugcinwa lokukahle, kanye nekusebenta lokutsembekile, kwenta kutsi kuvame kakhulu ekusebentiseni njalo. Ngakulolunye luhlangotsi, tinzuzo temavalvu esango le-stem langakhuphuki sakhiwo sawo lesincane kanye nekwakhiwa kwekonga sikhala, kepha loku kufika ngekucitsa kubonakala kanye nekunakekelwa kalula, ngako-ke kuvame kusetjentiswa etimeni letinesikhala lesitsite. Uma ukhetsa, kufanele uncume kutsi nguluphi luhlobo lwevalve yesango lokufanele ulusebentise ngekuya ngesikhala lesitsite sekufaka, timo tekunakekelwa, kanye nendzawo yekusebenta. Ngetulu kwesikhundla sayo sekuhola emkhakheni wemavalvu esango, i-TWS iphindze futsi yakhombisa emakhono lacinile ebuchwepheshe etindzaweni letinyenti letifana ne-emavalvu evivane, hlola emavalvu, futsiemavalvu ekulinganisa. Singakusita kutsi ukhetse luhlobo lolulungile lwesicelo sakho futsi semukele litfuba lekululungiselela tidzingo takho ngco. Sitawuniketa inchazelo leningilizako yemehluko emkhatsini wemavalvu esango lesicu lesikhuphukako kanye nesicu lesingakhuphuki esigabeni setfu lesilandzelako. Hlala ubukele.
