I-Valve njengethuluzi izalwe izinkulungwane zeminyaka

I-valveiyithuluzi elisetshenziswa ekudluliselweni nasekulawuleni igesi noketshezi okungenani iminyaka eyinkulungwane yomlando.

Njengamanje, ohlelweni lwamapayipi oketshezi, i-valve elawulayo iyisici sokulawula, futhi umsebenzi wayo oyinhloko ukuhlukanisa amathuluzi kanye nesistimu yamapayipi, ukulawula ukugeleza, ukuvimbela ukubuyela emuva, ukulawula nokukhipha ingcindezi. Njengoba kubaluleke kakhulu ukukhetha i-valve yokulawula efaneleka kakhulu yesistimu yepayipi, kubaluleke kakhulu ukuqonda izici ze-valve kanye nezinyathelo kanye nesisekelo sokukhetha i-valve.

Ukucindezela okujwayelekile kwe-valve

Ukucindezela okulinganiselwe kwe-valve kubhekisela kumklamo onikezwe ingcindezi ehlobene namandla omshini wezingxenye zamapayipi, okusho ukuthi, ingcindezi yokusebenza evumelekile ye-valve ezingeni lokushisa elishiwo, elihlobene nempahla ye-valve. . Ukucindezela kokusebenza akufani, ngakho-ke, ukucindezela okuzisholo kuyipharamitha encike ezintweni ze-valve futhi ihlobene nokushisa okuvumelekile okusebenzayo nokucindezela kokusebenza kwezinto.

I-valve iyisikhungo ohlelweni lokujikeleza okuphakathi noma uhlelo lokucindezela, olusetshenziselwa ukulungisa ukugeleza noma ukucindezela kwe-medium. Eminye imisebenzi ihlanganisa ukuvala noma ukuvula imidiya, ukulawula ukugeleza, ukushintsha isiqondiso sokugeleza kwemidiya, ukuvimbela ukugeleza kwemidiya, nokulawula noma ukukhipha ingcindezi.

Le misebenzi ifinyelelwa ngokulungisa indawo yokuvalwa kwe-valve. Lokhu kulungiswa kungenziwa ngesandla noma ngokuzenzakalelayo. Ukusebenza mathupha kuhlanganisa nokusebenza kokulawula mathupha idrayivu. Ama-valve asebenza ngesandla abizwa ngokuthi ama-manual valves. I-valve evimbela ukubuyela emuva ibizwa ngokuthi i-valve yokuhlola; lowo olawula ingcindezi yokusiza ubizwa ngokuthi i-valve yokuphepha noma i-valve yokusiza ukuphepha.

Kuze kube manje, imboni ye-valve ikwazile ukukhiqiza uhla oluphelele lweama-valve esango, ama-globe valves, ama-throttle valves, amapulaki ama-valve, ama-ball valves, ama-valve kagesi, ama-diaphragm control valve, ama-sheke ama-valve, ama-valve okuphepha, ama-valve okunciphisa ukucindezela, izicupho zesitimu kanye nama-valve okuvala okuphuthumayo. Imikhiqizo ye-valve yezigaba eziyi-12, amamodeli angaphezu kuka-3000, kanye nokucaciswa okungaphezulu kuka-4000; ukucindezela okukhulu kokusebenza ngu-600MPa, ububanzi bokulinganisa okuphezulu ngu-5350mm, izinga lokushisa eliphezulu lokusebenza ngu-1200℃, izinga lokushisa elincane lokusebenza ngu--196℃, futhi isisetshenziswa esisebenzayo Amanzi, isitimu, uwoyela, igesi yemvelo, imidiya edlayo enamandla (njenge-nitric acid egxilile, i-medium concentration sulfuric acid, njll.).

Naka ukukhetha ama-valve:

1. Ukuze kuncishiswe ukujula kwepayipi lokumboza inhlabathi,ivalve uvemvanengokuvamile ikhethelwa ipayipi elikhulu lobubanzi; ukungahambi kahle okuyinhloko kwe-butterfly valve yukuthi ipuleti ye-butterfly ithatha ingxenye ethile yesiphambano samanzi, okwandisa ukulahlekelwa kwekhanda elithile;

2. Ama-valve avamile ahlanganisaizivalo uvemvane, ama-valve esango, ama-valve amabhola nama-plug valves, njll. Ububanzi bama-valve asetshenziswa kunethiwekhi yokuphakelwa kwamanzi kufanele bucatshangelwe ekukhethweni.

3. Ukuphonswa nokucutshungulwa kwama-valve ebhola nama-plug valves kunzima futhi kuyabiza, futhi ngokuvamile afanele amapayipi amancane naphakathi nendawo. I-valve yebhola kanye ne-plug valve igcina izinzuzo ze-valve yesango elilodwa, ukumelana nokugeleza kwamanzi amancane, ukubekwa uphawu okuthembekile, isenzo esivumelana nezimo, ukusebenza okulula nokugcinwa. I-valve yepulaki nayo inezinzuzo ezifanayo, kodwa isigaba sokudlula amanzi akuwona umbuthano ophelele.

4. Uma inomthelela omncane ekujuleni komhlabathi wekhava, zama ukukhetha i-valve yesango; ukuphakama kwe-valve yesango likagesi ivelufu yesango elikhulu enobubanzi obume mpo kuthinta ukujula kwepayipi elimboza inhlabathi, futhi ubude be-valve yesango elivundlile enobubanzi obukhulu kukhulisa indawo evundlile ehlala ipayipi futhi kuthinta ukuhlelwa kwamanye amapayipi;

5. Eminyakeni yamuva, ngenxa yokuthuthukiswa kobuchwepheshe bokuphonsa, ukusetshenziswa kwe-resin sand casting kungagwema noma kunciphise ukucutshungulwa komshini, ngaleyo ndlela kunciphise izindleko, ngakho-ke ukuba nokwenzeka kwama-valve ebhola asetshenziswa kumapayipi anobubanzi obukhulu kufanelekile ukuhlola. Ngokuqondene nomugqa wokuklama wesayizi we-caliber, kufanele ucatshangelwe futhi uhlukaniswe ngokuvumelana nesimo esithile.
