Iyini i-Triple Offset Butterfly Valve: Uma kuqhathaniswa nohlobo oluyi-Concentric

Iyini i-Triple Offset Butterfly Valve: umehluko phakathi kwama-concentric kanye nama-high-performance butterfly valve

Emkhakheni wamavalvu ezimboni, amavalvu amavemvane asetshenziswa kabanzi ekulawuleni uketshezi ngenxa yesakhiwo sawo esincane kanye nokuvulwa nokuvalwa okusheshayo. Ngokuthuthuka kobuchwepheshe, ukwakheka kwamavalvu amavemvane kuye kwathuthukiswa njalo, okuholele ezinhlotsheni eziningi ezifanaivalvu yebhabhathane eliseceleni, ivalvu yebhabhathane ephindwe kabilifuthiivalvu yebhabhathane engavamile kathathuLesi sihloko sizoqala ngesimiso sokwakheka, ukuqhathanisa ukusebenza kanye nezincomo zokukhetha, sihlaziye ngokujulile izinzuzo eziyinhloko zalokhuivalvu yebhabhathane engavamile kathathu, futhi uhlole ukuthi ungayikhetha kanjani ikhwalithi ephezuluabakhiqizi bama-valve e-butterflyfuthiabahlinzeki.

Ukuhlukaniswa kanye Nezimpawu Zesakhiwo Sama-Butterfly Valve

 1. I-Concentric Butterfly Valve

 - Izici zesakhiwo: Ipuleti levalvu liyi-coaxial nesiqu sevalvu, indawo yokuvala iklanywe ngokulinganayo, futhi isihlalo sevalvu sivame ukwenziwa ngezinto ezithambile (njengerabha).

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

- Ukungalungi: Ukumelana okukhulu kokungqubuzana, kanye nokusebenza kokuvala kwehla ngokukhuphuka kwezinga lokushisa kanye nengcindezi.

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

2. I-Double Eccentric Butterfly Valve

- Izici zesakhiwo:

- Ukungajwayelekile kokuqala: isiqu sevalvu siyaphambuka enkabeni yepuleti levalvu ukuze kuncishiswe ukungqubuzana kokuvula nokuvala.

- Ukungafani kwesibili: ubuso bokuvala ipuleti le-valve buyaphambuka emgqeni ophakathi wepayipi ukuze kufezwe ukuvala okungathintani.

- Izinzuzo: i-torque encane yokuvula nokuvala, ukusebenza kokuvala okungcono kune-valve ye-butterfly engaphakathi.

- Ukungalungi: izinto zokuvala zithambekele ekugugeni ngaphansi kokushisa okuphezulu kanye nokucindezela okuphezulu.

- Izimo zohlelo lokusebenza: amapayipi omfutho ophakathi nendawo kanye nophansi ezimbonini zikaphethiloli kanye namakhemikhali.

3. Ivalvu Yebhabhathane E-Eccentric Ethathu

- Izici zesakhiwo:

- Ukungajwayelekile kokuqala: isiqu sevalvu siyaphambuka enkabeni yepuleti levalvu.

- Ukungafani kwesibili: ubuso bokuvala ipuleti le-valve buyaphambuka emgqeni ophakathi wepayipi.

- Ukungafani okwesithathu: umklamo we-angle yekhoni yokuvala ubuso ufeza ukuvalwa kwensimbi okuqinile.

- Izinzuzo:

- Ukuvulwa nokuvalwa kwe-zero friction: Ipuleti levalvu kanye nesihlalo sevalvu kuthintana kuphela uma kuvaliwe, okwandisa isikhathi sokuphila kwenkonzo.

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

- Ukuvalwa kwezinhlangothi ezimbili: Ifanele izimo zokusebenza ezinzima lapho i-medium igeleza khona kuzo zombili izinhlangothi.

- Izimo zohlelo lokusebenza: Izinhlelo ezibalulekile ezinezinga lokushisa eliphezulu kanye nomfutho ophezulu njengamandla, i-petrochemical, kanye ne-LNG.

4. I-valve ye-Butterfly Esebenza Kakhulu

- Incazelo: Ngokuvamile kubhekisela ku-valve yebhabhathane enesakhiwo esiphindwe kabili noma esiphindwe kathathu, esinezici ze-torque ephansi, ukuvala okuphezulu kanye nokuphila isikhathi eside.

- Izinzuzo eziyinhloko: Ingathatha indawo yama-valve esango nama-valve ebhola futhi inciphise izindleko zezinhlelo zamapayipi.

Kungani i-valve yebhabhathane e-eccentric kathathu iyisinqumo sokuqala embonini

 1. Ukuhlaziywa kwezinzuzo zesakhiwo

- Umklamo wophawu oluqinile lwensimbi: Yenziwe ngensimbi engagqwali, insimbi ye-alloy nezinye izinto, ayigqwali futhi ayigugi.

- Ubuso bokuvala obuyindilinga: ukuxhumana okuqhubekayo kwakheka lapho kuvalwa, futhi uphawu luqina kakhulu.

- Umklamo wokuphepha komlilo: amanye amamodeli ahlangabezana nesitifiketi se-API 607 ​​esingashisi futhi afaneleka ezindaweni eziyingozi.

2. Ukuqhathaniswa ne-valve yebhabhathane ephindwe kabili

3. Amacala okusetshenziswa embonini

- Imboni yamandla: isetshenziswa ohlelweni lwamanzi okuphakelwa kwebhoyila, imelana nomusi oshisayo ophakeme.

- Amakhemikhali e-Petrochemical: Lawula imidiya ebolile kumayunithi okuqhekeka kwe-catalytic.

- Isitoreji kanye nokuthuthwa kwe-LNG: Gcina ukuthembeka kokuvala ngaphansi kwezimo zokushisa eziphansi kakhulu.

Indlela yokukhetha abakhiqizi nabahlinzeki be-butterfly valve abasezingeni eliphezulu 

1. Bheka amandla obuchwepheshe

- Amalungelo obunikazi kanye nezitifiketi: Beka phambiliabakhiqiziabanobuchwepheshe be-valve ye-butterfly e-triple-eccentric enelungelo lobunikazi futhi abaqinisekiswe yi-API 609 kanye ne-ISO 15848.

- Amakhono okwenza ngokwezifiso: Ungawanikeza ama-valve anosayizi ongewona ojwayelekile kanye nezinto ezikhethekile (njengeMonel, Inconel).

2. Bheka ukulawulwa kwekhwalithi yokukhiqiza

- Ukuhlolwa kwezinto ezibonakalayo: Imibiko yezinto ezibonakalayo (njengezindinganiso ze-ASTM) iyadingeka.

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

3. Bheka intengo kanye nekhono lokulethwa

- Izinzuzo zezimboni zaseShayina:

- Ukuncintisana kwamanani: IsiShayinaabahlinzeki be-butterfly valvebathembele ekukhiqizweni okukhulu, futhi intengo iphansi ngo-30%-50% kuneyemikhiqizo yaseYurophu naseMelika.

- Ukulethwa okusheshayo: Uhlu olwanele lwemikhiqizo ejwayelekile, olusekela amasonto ama-2-4 okulethwa.

4. Bheka isevisi yangemva kokuthengisa

- Nikeza isiqondiso sokufakwa endaweni, ukulungiswa njalo kanye nokuhlinzekwa kwezingxenye ezisele.

Izitayela zesikhathi esizayo zamavalvu ebhabhathane anezinhlangothi ezintathu

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

2. Ukusetshenziswa kwezinto ezinobungani nemvelo: Yamukela umklamo ongenawo amanzi kanye nokukhishwa okuphansi komoya okusabalalayo (isitifiketi se-ISO 15848).

3. Ukwandiswa kwensimu yokushisa okuphansi kakhulu: Isebenza ezimweni zokusebenza ezimbi kakhulu njenge-hydrogen ewuketshezi (-253℃) kanye ne-helium ewuketshezi.

Isiphetho 

Ivalvu yebhabhathane eliyi-eccentric kathathuisibe yivalvu ekhethwayo yamapayipi ezimboni anokushisa okuphezulu kanye nomfutho ophezulu ngesakhiwo sayo sokuvala insimbi esiqinile esishintshashintshayo kanye nokuphila kwayo isikhathi eside kakhulu. Ukuqhathanisa izinzuzo zokusebenza neivalvu yebhabhathane ephindwe kabilinoma ukuhlukanisa izimo zohlelo lokusebenza ngeivalvu yebhabhathane eliseceleni, kubalulekile ukukhethaumenzi wevalvu yebhabhathanengobuchwepheshe obuthembekile kanye nentengo efanelekile.Izimboni zamavalvu ezibhabhathaneeShayina seziba yisisekelo esiyinhloko sokuthengwa komhlaba wonke ngochungechunge lwazo lobuchwepheshe obuvuthiwe kanye nezinzuzo zezindleko. Uma ufuna ukwazi okwengeziweivalvu yebhabhathane esebenza kahle kakhuluimingcele yobuchwepheshe noma uthole isilinganiso, sicela uxhumane nathi - umhlinzeki wezixazululo zevalvu ochwepheshe!
