Isingeniso
Ezinhlelweni zokulethwa koketshezi ezikhiqizwa yizimboni, ukwakhiwa kukamasipala kanye nempilo yansuku zonke, amavalvu enziwa ngesandla ayizingxenye ezibalulekile ezifinyelela ukulawula okunembile koketshezi ngokusebenza ngezandla. Kusukela kunethiwekhi eyinkimbinkimbi yamapayipi ezindaweni zokusebenzela zasefekthri kuya kompompi basemakhishini asekhaya, ama-valve asebenza ngezandla angabonakala yonke indawo. Njengamanje, imboni yomhlaba wonke iphokophele ekuhlakanipheni nasekusebenzeni kahle. Nakuba ama-valve okwenziwa ngesandla engokwesiko, ayaqhubeka nokwenza impumelelo ekusungulweni kwezinto ezibonakalayo kanye nokwenza kahle kwesakhiwo, futhi ayaqhubeka nokufaka isandla ekuthuthukisweni kwemikhakha ehlukahlukene.
Ukuhlaziywa okuyisisekelo kwe-valve ngesandla
I-valve eyenziwa ngesandla iyisisetshenziswa esisebenzisa amandla omuntu, njengesondo lesandla, isibambo, i-lever noma i-sprocket, ukulawula ukugeleza koketshezi (amanzi, umusi, uwoyela, igesi, imidiya ebolayo, njll.) epayipini. Ngokuyinhloko yakhiwe umzimba we-valve, isiqu se-valve, uphawu kanye nengxenye yokushayela. Ngesikhathi sokusebenza, isondo lesandla liphendulwa ngesandla ukuze lishayele isiqu se-valve, futhi isiqu se-valve sishayela umongo we-valve ukuze uhambe esihlalweni se-valve, sishintsha igebe phakathi kwe-valve core nesihlalo se-valve ukuze kuzuzwe ukuqhutshwa koketshezi, ukunqamuka noma ukulawula ukugeleza. .
Njengomzimba oyinhloko we-valve, umzimba we-valve udinga ukumelana nokucindezela kwamanzi, ukugqwala neminye imiphumela, futhi wenziwa ngezinto ezihlukahlukene. Ezivamile zihlanganisa insimbi ekhonjiwe, enezindleko eziphansi kanye nokumelana nokucindezela okuhle, futhi isetshenziselwa amapayipi avamile amanzi kanye nesitimu; insimbi engagqwali inokumelana nokugqwala okuqinile futhi ifanele izimboni ezifana nemboni yamakhemikhali nokudla okunezidingo eziphakeme zokuhlanzeka nokumelana nokugqwala; ama-alloys ethusi asetshenziswa kakhulu ukuhlinzeka ngamanzi kanye nokukhipha amanzi kanye namapayipi egesi ezakhiweni zomphakathi.
Izinhlobo eziyinhloko nezindlela zokusebenza
3.1 Amavalvu esango
Amavalvu esango avula-uketshezi ngokuphakamisa nokwehlisa isango ngendlela eqondile yesihlalo sevalvu. Lapho ivuliwe ngokugcwele, isango liphakanyiswa ngokugcwele, futhi uketshezi ludlula cishe ngokungavinjelwa, ngokumelana nokugeleza okuphansi. Ifanele izimo ezivuleke ngokuphelele nezivaleke ngokugcwele zamapayipi-amakhulu anobubanzi, njengamapayipi ahambisa amanzi emadolobheni, ukuze kuqinisekiswe ukulethwa okuzinzile kwamanzi amaningi. Kodwa-ke, isango nesihlalo se-valve kujwayele ukugqoka, futhi akufanelekile ukuvulwa njalo nokuvala nokulungiswa kokugeleza. .
3.2 Ama-valve wokumisa
I-valve yokumisa ilawula uketshezi ngokuphakamisa nokwehlisa i-disc ye-valve ngomugqa omaphakathi wesihlalo se-valve. I-valve disc isondelene nesihlalo se-valve, inokusebenza kahle kokuvala, ingalungisa kahle ukugeleza, futhi inokuqondisa. Lapho ufaka, udinga ukunaka isiqondiso sokugeleza koketshezi. Isetshenziswa kakhulu kumapayipi esitimu, amapayipi okuthutha amakhemikhali, njll., futhi ingalawula ngokunembile ukugeleza nokucindezela. Kodwa-ke, lapho uketshezi lugeleza nge-valve yokumisa, idinga ukushintsha isiqondiso sokugeleza, futhi ukumelana kukhulu kakhulu. .
3.3 Ama-valve amabhola
I-valve yebhola isebenzisa i-sphere njengomongo we-valve, futhi kunesiyingi embobeni endimeni. Uma i-sphere izungeziswe ngama-degree angama-90 futhi imbobo edlulayo ihambisana nepayipi, uketshezi luyaqhutshwa; uma ime mpo, iyanqunywa. Kulula ukuyisebenzisa, iyashesha ukushintsha, inokumelana nokugeleza okuncane, futhi ingakwazi ukuzivumelanisa nokucindezela okuphezulu, izinga lokushisa eliphezulu kanye nemidiya ebolayo. Isetshenziswa kakhulu ku-petrochemical, ezokuthutha igesi yemvelo nakweminye imikhakha, njengamaloli amathangi, ukunqanyulwa kwamapayipi egesi nokulawula. .
3.4 I-valve ye-Butterfly
I-butterfly plate ye-butterfly valve ine-disc-futhi izungeza i-axis yevalvu ukuze ivuleke futhi ivale. Inesakhiwo esilula, usayizi omncane, isisindo esilula, kanye nezidingo zesikhala sokufaka esiphansi. Inezinzuzo ezisobala kumapayipi-awububanzi obukhulu, njengezizinda zasemadolobheni zokukhuculula indle namapayipi amanzi ekwakheni amasistimu e-HVAC. Ingakwazi ukulungisa ngokushesha ukugeleza, kodwa ukusebenza kwayo kokuvala akunamandla uma kuqhathaniswa nama-valve esango kanye nama-valve okumisa.

Amathrendi Embonini Nokuqondisa Kwekusasa
Njengamanje, ama-valve enziwa ngesandla athatha ingxenye enkulu yemakethe yama-valve yomhlaba. Ngokwezibalo ezifanele, ezinhlelweni zamapayipi anobubanzi obuncane naphakathi nendawo kanye nemvamisa yokusebenza ephansi, ama-valve asebenza ngesandla athatha ngaphezu kuka-60% wesabelo semakethe, futhi kunesidingo esinamandla kumaphrojekthi wokwakhiwa kwengqalasizinda emazweni asathuthuka. .
Imboni igxile ekusungulweni kwezinto ezintsha, ukusebenzisa izitsha zobumba ezintsha,{0}}amapulasitiki asebenza kahle, njll. njengezinto zokuvala ukuze kuthuthukiswe ukumelana nokuguga, ukumelana nokugqwala kanye nokuvala amavalvu; ukwenza kahle ukwakheka kwesakhiwo, njengokwakha izakhiwo zesango elisha, ukunciphisa ukungezwani phakathi kwamasango nezihlalo zamavalvu, nokwelula impilo yesevisi. Ngokuzayo, ama-valve okwenziwa ngesandla azothuthukela ekukhanyeni, esebenzisa izinto ezifana nama-alloys angasindi ukunciphisa izindleko zokufaka nezokuthutha; ngokobuhlakani, kuhlanganiswe nezinzwa kanye nobuchwepheshe be-inthanethi Yezinto ukuze kuzuzwe ukubhekwa kwesimo esikude nesixwayiso samaphutha; izinsizakalo ezenziwe ngokwezifiso nazo zizophelela kakhulu, futhi izixazululo ze-valve ezikhethekile zizofanelana nezidingo zezimboni ezahlukene nezimo zokusebenza.
Izindawo zokusebenzisa ama-valve okwenziwa ngesandla kanye nesabelo semakethe
| Izindawo zokufaka izicelo | Isabelo semakethe | Imisebenzi esemqoka |
| Ukukhiqizwa kwezimboni | 40% | Lawula ukuhamba kwemidiya yezimboni futhi uqinisekise ukuzinza kwezinqubo zokukhiqiza |
| Ubunjiniyela bakamasipala | 25% | Phatha amanzi asemadolobheni, igesi namanye amapayipi asetshenziswa umphakathi |
| Ukwakhiwa komphakathi | 15% | Ukuhlangabezana nezidingo zokuhlinzekwa kwamanzi, ukugeleza kwamanzi kanye nokufudumeza ezindlini nezakhiwo |
| Inkambu yamandla | 10% | Ukusiza ekulawuleni abezindaba ekukhiqizeni amandla nasekuthuthweni |
| Eminye imikhakha (njengokudla nesiphuzo, imithi, njll.) | 10% | Hlangana nezidingo zezimboni ezikhethekile zokuhlanzeka koketshezi kanye nokulawula okunembayo |
Njengesisetshenziswa sokulawula uketshezi “esingumakadebona” ezimbonini nempilo yansuku zonke, ama-valve asebenza ngezandla athembele ekusungulweni okusha ukuze aqhubeke nokukhipha amandla ezimbonini ezihlukahlukene. Ngokuzayo, bazokhombisa inani eliyingqayizivele ezimweni ezintsha kanye nezidingo ezintsha.
