I-valve njengethuluzi izalwe izinkulungwane zeminyaka

I-valveiyithuluzi elisetshenziswe ekudluliseleni nasekulawuleni igesi noketshezi okungenani okungenani iminyaka eyinkulungwane yomlando.

Njengamanje, ohlelweni lwePipeline Pipeline, i-valve elawula i-valve eyengeziwe, futhi umsebenzi wayo oyinhloko ukuhlukanisa imishini kanye nohlelo lwepayipi, lawula ukugeleza, uvikele futhi ukhiphe ingcindezi. Njengoba kubaluleke kakhulu ukukhetha i-valve efanelekayo kakhulu yohlelo lwamapayipi, kubalulekile futhi ukuqonda izici ze-valve nezinyathelo kanye nokukhetha i-valve.

Ingcindezi yokuqothuka ye-valve

Ingcindezi yokuqothuka ye-valve isho umdwebo onikezwe ingcindezi ohlobene namandla okusebenza kwezinto zamapayipi, okusho ukuthi, kuyingcindezi yokusebenza evunyelwe ye-valve ekushiseni okucacisiwe, okuhlobene nokuqukethwe kwe-valve. Ingcindezi yokusebenza ayifani, ngakho-ke, ingcindezi yokuphakama yipharamitha exhomekeke ngokuqukethwe kwe-valve futhi kuhlobene nokushisa okuvumelekile kokusebenza kanye nokucindezela kokusebenza kwezinto ezibonakalayo.

I-valve iyisikhungo kuhlelo lokujikeleza oluphakathi nendawo noma uhlelo lokucindezela, olusetshenziselwa ukulungisa ukugeleza noma ingcindezi ye-medium. Eminye imisebenzi ifaka ukuvala noma ukushintshela ku-Media, Ukulawula Ukugeleza, Ukushintsha Ukuholwa Kwemidiya, Ukuvimbela I-Media Backflow, nokulawula noma Ukulawula Ingcindezi.

Le misebenzi itholakala ngokulungisa isikhundla sokuvalwa kwe-valve. Lokhu kulungiswa kungenziwa ngesandla noma ngokuzenzakalelayo. Ukusebenza ngesandla kuhlanganisa nokusebenza kokulawula idrayivu. Ama-valves asebenza ngesandla abizwa ngokuthi ama-valves wezandla. I-valve evimbela i-backflow ibizwa nge-valve yesheke; Lowo olawula ingcindezi yokusiza ubizwa nge-valve yokuphepha noma i-valve yokuphepha.

Kuze kube manje, imboni ye-valve ikwazile ukukhiqiza uhla oluphelele lweama-gang valves, ama-valves we-threen, ama-throttle ama-valves, ama-valves we-plag, ama-valves kagesi, ama-valves e-diaphragm, ama-valves wokuhlola, ama-valves okuphepha, izicupho zesimo sezulu kanye nama-valve avaliwe aphuthumayo. Imikhiqizo ye-Valve yezigaba eziyi-12, amamodeli angaphezu kuka-3000, nezincazelo ezingaphezu kuka-4000; Ingcindezi yokusebenza ephezulu yi-600MPA, ububanzi obuphakeme obukhulu bungama-5350mm, izinga lokushisa eliphakeme lingu-1200℃, izinga lokushisa eliphansi lingu -196℃, futhi okuphakathi okusebenzayo kumanzi, umusi, uwoyela, igesi yemvelo, imidiya eqinile eqinile (njenge-nitric acid, i-sulfuric acid ehlanganisiwe, i-aulfuric acid ephakathi, njll.).

Naka Ukukhetha kwe-Valve:

1. Ukuze sinciphise inhlabathi emboza ukujula kwepayipi,I-valve yevemvanengokuvamile kukhethwe ngepayipi elikhudlwana elibanzi; ukungathandeki okuyinhloko kwe-butterfly valve ukuthi ipuleti levemvane lithatha ingxenye ethile yesiphambano samanzi, esandisa ukulahleka kwekhanda okuthile;

2. Ama-valves ajwayelekile afakaama-butterfly valves, ama-gang valves, ama-valves ebhola nama-valves ama-plug, njll. Ububanzi bama-valve asetshenziswa kunethiwekhi yokuhlinzekwa kwamanzi kufanele kubhekwe ekukhetheni.

I-3. Ukuphonsa nokucutshungulwa kwama-valves ebhola kanye nama-plex valves kunzima futhi kubiza kakhulu, futhi ngokuvamile alungele amapayipi amancane naphakathi nendawo. I-Ball valve ne-valve ye-plug Gcina izinzuzo ze-valueve eyodwa, ukumelana kwamanzi okuncane, ukubekwa uphawu okuthembekile, isenzo esiguqukayo, ukusebenza okulula nokulungisa. I-plug valve ibuye ibe nezinzuzo ezifanayo, kepha isigaba esiphasiswe amanzi akuyona indilinga ephelele.

4. Uma kungenamthelela omncane ekujuleni kwesembozo sekhava, zama ukukhetha i-valve valve; Ukuphakama kwesango kagesi i-valve enkulu-ububanzi obumile buthinta ukujula kwethanga lomhlabathi, kanye nobude be-cangve enkulu evundlile kukhulisa indawo evundlile ethathwe yipayipi futhi kuthinta ukuhlelwa kwamanye amapayipi;

I-5. Eminyakeni yamuva nje, ngenxa yokuthuthuka kobuchwepheshe bokuphonsa, ukusetshenziswa kwe-resin sand casting kungakugwema noma kunciphise ukucubungula imishini, ngakho-ke ukwehlisa izindleko, ngakho-ke kungenzeka ukuthi ama-valves webhola asetshenziswa kumapayipi amakhulu abuyisiwe kufanelekile ukuhlola. Ngokuqondene nomugqa wokulumaza wesayizi, kufanele ubhekwe futhi uhlukaniswe ngokwesimo esithile.
