Iyini i-Triple Offset Butterfly Valve: Vs. Uhlobo lwe-Concentric

Iyini i-Triple Offset Butterfly Valve: umehluko phakathi kwama-butterfly agxilile nokusebenza okuphezulu

Emkhakheni wama-valve ezimbonini, ama-butterfly valves asetshenziswa kakhulu ekulawuleni uketshezi ngenxa yesakhiwo sawo esihlangene nokuvulwa nokuvala ngokushesha. Ngokuthuthuka kobuchwepheshe, ukuklanywa kwama-valve ovemvane kuye kwathuthukiswa ngokuqhubekayo, okuholela ezinhlotsheni eziningi ezifanai-centerline butterfly valve, i-valve ye-butterfly ephindwe kabilifuthitriple eccentric butterfly valve. Lesi sihloko sizoqala ngomgomo wesakhiwo, ukuqhathanisa ukusebenza kanye nezincomo zokukhetha, sihlaziye ngokujulile izinzuzo eziyinhloko zetriple eccentric butterfly valve, futhi uhlole indlela yokukhetha ikhwalithi ephezuluabakhiqizi be-butterfly valvefuthiabahlinzeki.

Ukwahlukaniswa Nezimo Zesakhiwo Samavavu Ovemvane

 1. I-Concentric Butterfly Valve

 - Izici zesakhiwo: I-valve plate i-coaxial nesiqu se-valve, indawo yokuvala iklanywe ngokulinganayo, futhi isihlalo sevalvu ngokuvamile senziwe ngezinto ezithambile (njengerabha).

- Izinzuzo: Izindleko eziphansi, isakhiwo esilula, esifanele ukucindezela okuphansi kanye nezimo zokushisa ezivamile.

- Ukubi: Ukumelana nokungqubuzana okukhulu, nokusebenza kokuvala kwehla ngokunyuka kwezinga lokushisa nokucindezela.

- Izimo zohlelo lokusebenza: izimo zokusebenza ezingezona ezinzima ezifana nokwelashwa kwamanzi, i-HVAC, njll.

2. I-Double Eccentric Butterfly Valve

- Izici zesakhiwo:

- I-eccentricity yokuqala: Isiqu se-valve siyachezuka phakathi nendawo ye-valve plate ukuze kuncishiswe ukungqubuzana kokuvula nokuvala.

- I-eccentricity yesibili: indawo yokuvala ipuleti ye-valve iyachezuka emugqeni ophakathi nendawo wepayipi ukuze kufinyelelwe ukuvala okungathinteki.

- Izinzuzo: i-torque encane yokuvula nokuvala, ukusebenza kangcono kokuvala kune-valve butterfly ephakathi nendawo.

- Ukubi: into yokuvala uphawu ijwayele ukuguga ngaphansi kokushisa okuphezulu nokucindezela okukhulu.

- Izimo zohlelo lokusebenza: amapayipi anengcindezi emaphakathi nephansi ezimbonini ze-petroleum namakhemikhali.

3. I-Triple Eccentric Butterfly Valve

- Izici zesakhiwo:

- I-eccentricity yokuqala: isiqu se-valve siyachezuka phakathi nendawo yepuleti levalvu.

- I-eccentricity yesibili: indawo yokuvala ipuleti ye-valve iyachezuka emugqeni omaphakathi wepayipi.

- I-eccentricity yesithathu: i-design ye-engeli ye-cone yokuvala ifinyelela ukutywinwa okuqinile kwensimbi.

- Izinzuzo:

- I-Zero friction ukuvula nokuvala: Ipuleti le-valve kanye nesihlalo se-valve kuxhumene kuphela uma kuvaliwe, okwandisa impilo yesevisi.

- Ukushisa okuphezulu nokumelana nokucindezela okuphezulu: Izigxivizo zensimbi zingamelana namazinga okushisa angaphezu kuka-400 ℃ kanye namazinga okucindezela e-Class 600.

- Ukubekwa uphawu kabili: Ifanele izimo zokusebenza ezinzima lapho okuphakathi kugeleza kuzo zombili izinkomba.

- Izimo zohlelo lokusebenza: Amasistimu angukhiye anezinga lokushisa eliphezulu nokucindezela okuphezulu okunjengamandla, i-petrochemical, ne-LNG.

4. Ukusebenza okuphezulu kwe-Butterfly Valve

- Incazelo: Ngokuvamile ibhekisela ku-valve ye-butterfly ene-eccentric ephindwe kabili noma isakhiwo se-eccentric kathathu, esinezici ze-torque ephansi, ukuvalwa okuphezulu nokuphila isikhathi eside.

- Izinzuzo eziyinhloko: Ingakwazi esikhundleni samavalvu esango kanye nama-valve ebhola futhi yehlise izindleko zezinhlelo zamapayipi.

Kungani ivalve yevemvane eyi-triple eccentric iyinketho yokuqala embonini

 1. Ukuhlaziywa kwezinzuzo zesakhiwo

- Metal hard seal design: Yenziwe ngensimbi engagqwali, i-alloy steel nezinye izinto zokwakha, ayikwazi ukugqwala futhi ayigugi.

- I-Conical sealing surface: ukuthintana okuqhubekayo kwakheka lapho kuvalwa, futhi uphawu luqinile.

- Idizayini yokuphepha komlilo: amanye amamodeli ahlangabezana nesitifiketi sokuvikela umlilo se-API 607 ​​futhi afanele izindawo eziyingozi.

2. Ukuqhathanisa ne-double eccentric butterfly valve

3. Amacala ezicelo zemboni

- Imboni yamandla: isetshenziswa ohlelweni lwamanzi okuphakelayo kubhayela, amelana nokushisa okuphezulu kwesitimu.

- I-Petrochemical: Lawula imidiya eyonakalisayo kumayunithi okuqhekeka kwe-catalytic.

- Isitoreji se-LNG nezokuthutha: Gcina ukuthembeka kokuvala ngaphansi kwezimo zokushisa eziphansi kakhulu.

Indlela yokukhetha abakhiqizi be-butterfly valve abasezingeni eliphezulu nabahlinzeki 

1. Bheka amandla obuchwepheshe

- Amalungelo obunikazi kanye nezitifiketi: Beka kuqalaabakhiqiziabanobuchwepheshe be-valve uvemvane onelungelo lobunikazi obuphindwe kathathu futhi obugunyazwe i-API 609 ne-ISO 15848.

- Amakhono okwenza ngokwezifiso: Ungakwazi yini ukunikeza ama-valve anosayizi abangajwayelekile nezinto ezikhethekile (njenge-Monel, Inconel).

2. Bheka ukulawula izinga lokukhiqiza

- Ukuhlolwa kwezinto: Imibiko yezinto ezibonakalayo (njengamazinga e-ASTM) iyadingeka.

- Ukuhlolwa kokusebenza: Kubandakanya ukuhlolwa kokuvala kanye nokuhlolwa komjikelezo wempilo (njengokuvuleka nokuvalwa okungu-10,000 ngaphandle kokuvuza).

3. Bheka intengo namandla okulethwa

- Izinzuzo zezimboni zaseShayina:

- Ukuncintisana kwentengo: IsiShayinabutterfly valve abahlinzekizithembele ekukhiqizeni okukhulu, futhi intengo iphansi ngo-30% -50% kunaleyo yemikhiqizo yaseYurophu neyaseMelika.

- Ukulethwa okusheshayo: Uhlu olwanele lwemikhiqizo ejwayelekile, esekela amaviki angu-2-4 okulethwa.

4. Bheka isevisi yangemuva kokuthengisa

- Nikeza isiqondiso sokufakwa esizeni, ukunakekelwa okuvamile kanye nokuhlinzekwa kwezingxenye ezisele.

Amathrendi wesikhathi esizayo wamavalvu evemvane ane-eccentric emithathu

1. Ukuthuthukiswa okuhlakaniphile: Izinzwa ezihlanganisiwe namamojula we-IoT ukuqapha isimo se-valve ngesikhathi sangempela.

2. Isicelo sezinto ezibonakalayo ezinobungani bemvelo: Yamukela idizayini engavuziyo kanye nezikhithi eziphansi zokubalekela (isitifiketi se-ISO 15848).

3. Ukunwetshwa kwenkambu yezinga lokushisa eliphansi kakhulu: Isebenza ezimeni zokusebenza ngokwedlulele njenge-liquid hydrogen (-253℃) ne-helium ewuketshezi.

Isiphetho 

I-valve yevemvane eyi-eccentric kathathuisiphenduke ivalvu ekhethwayo yamapayipi ezimboni anezinga lokushisa eliphezulu kanye nengcindezi ephezulu nesakhiwo sayo sensimbi esishintshashintshayo sophawu oluqinile nempilo yesevisi yesikhathi eside. Ukuthi uqhathanisa izinzuzo zokusebenza nei-valve ye-butterfly ephindwe kabilinoma ukuhlukanisa izimo zohlelo lokusebenza ngei-centerline butterfly valve, kubalulekile ukukhetha aumkhiqizi we-butterfly valvengobuchwepheshe obuthembekile namanani aphusile.Izimboni ze-Butterfly valvee-China isiba isisekelo esiyisisekelo sokuthengwa kwempahla emhlabeni wonke ngochungechunge lwabo lobuchwepheshe obuvuthiwe kanye nezinzuzo zezindleko. Uma ufuna ukwazi okwengeziweivalve uvemvane esebenza kahle kakhuluimingcele yezobuchwepheshe noma uthole isaphulelo, sicela usithinte - umhlinzeki wesisombululo se-valve ochwepheshe!
