Umehluko phakathi kwamavalvu we-Butterfly wokuvala athambileko

1. Ukukhethwa kwepahla

Amavalvu aphasi

• Izinto zomzimba/Diski: Ngokuvamileko sebenzisa iinsimbi ezibizako ezifanainsimbinofana insimbi yekhabhoni engahlanganisiweko, engatlhoga ukujamelana nokugqwala eendaweni ezimbi.
• Iindandatho zokuvala: Yenziwe ngama-elastomers afana ne-NR (irabha yemvelo)nofana i-EPDM yezinga eliphasi, enokujamelana namakhemikhali okulinganiselweko nokubekezelela amazinga womtjhiso (isib., ≤80°C / 176°F).
• Shaft: Kanengi yakhiwa ngensimbi yekhabhoni ejayelekileko ngaphandle kokuhlanza indawo, ithambekele ekugqwaleni ebujameni obumanzi nofana obune-esidi.

Amavalvu aPhakathi-Phezulu 

• Izinto zomzimba/Diski: Sebenzisa izinto ezisezingeni eliphezulu ezifana ne-stainless steel (SS304/316), i-ductile iron, nofana i-aluminium bronze ukujamelana nokugqwala nokuqina kwemitjhini.
• Iindandatho zokuvala: Sebenzisa ama-elastomers asebenza kuhle khulu afana ne-EPDM, i-NBR, i-PTFE, nofana i-Viton®,ukunikela nge-brukuvumelana kwamakhemikhali (isib., ukujamelana namafutha, ama-asidi, nofana iinsombululo) kanye namazinga womtjhiso aphezulu (-20°C ukuya ku-150°C / -4°F ukuya ku-302°F).
• Shaft: Yenziwe ngensimbi engagqwali (SS410/316) eneendawo ezipholitjhiweko nofana ezigcotshiweko (isib., ukufakwa kwe-nickel) ukukhandela ukuguga nokuvuza.

1. Ukuklanywa kwezakhiwo nokukhiqiza

Amavalvu aphasi

• Idizayini elula: Izakhiwo ezisisekelo ezihlangeneko nofana ezihlangeneko ezinembileko yokuvala elinganiselwe. Idiski nesihlalo kungenzeka kube nokusetjenziswa okumbi, okurholela ekutheni kube nokuhlukunyezwa okuphezulu ne-torque.
• Umbuthano: Kanengi ikhiqizwa ngobunengi ngokulawulwa kwekhwalithi encani, okurholela ekubekezeleleni okungafaniko. Amazinga wokuvuza angabhalelwa kuhlangabezana namazinga aqinileko (isib., ukudlula iimfuneko ze-ANSI B16.104 zeKlasi VI).
• Ukusebenza:Ngokuvamileko ihlanganiswe nezibambo ezibizako ezibizako nofana ama-actuator kagesi asisekelo, angenamandla wokusebenza kanengi.

Amavalvu aPhakathi-Phezulu

• Idizayini ethuthukisiweko: Itshwayoizakhiwo eziphindwe kabili nofana eziphindwe kathathuukwehlisa ukutjhayisana, ukuthuthukisa ukusebenza kuhle kokuvala, nokunciphisa ukuguga. Ukwenza isibonelo, imiklamo ephindwe kabili yenza "umphumela wokugoqa" wokuvala okuqinileko.
• Ukukhiqiza ngokunembileko: Yenziwe ngemitjhini ye-CNC enembako ephezulu, ukuqinisekisa ukunyakaza kwediski okubushelelezi nokuthintana okuhle kwesivalo. Amazinga wokuvuza avamise ukuhlangabezana nofana ukudlula i-ISO 15848-1 (isib., i-Bubble-tight Class A).
• Ukusebenza: Ihambisana nama-actuator we-premium (ama-pneumatic, hydraulic, nofana ama-actuator kagesi ahlakaniphileko) weensetjenziswa ezinejubane elikhulu, ezinomjikelezo omkhulu. Amanye amamodeli afaka hlangana ama-positioner nofana iinzwa zempendulo zokwenza izinto ngokuzenzakalelako.

3. Ukusebenza nokuthembeka

Amavalvu aphasi

• Imikhawulo yokugandeleleka/yokutjhisa: Ilungele iinhlelo ezinomfutho ophasi (isib., ≤PN10 / Iklasi 125) kanye namazinga womtjhiso amancani. Ingabhalelwa eendaweni ezinomfutho omkhulu (isib., >PN16) nofana emazingeni womtjhiso aphezulu (-10°C ukuya ku-90°C).
• Ipilo yokuSebenza: Ifinyeziwe ngebanga lokuqina kwezinto ezimbi kanye namaphutha wokuklama, okutlhoga ukutlhogonyelwa njalo nofana ukutjhugululwa (isib., imijikelezo eli-10,000 ukuya ku-20,000).
• Ingozi yokuvuza: Ithuba eliphezulu lokutjhuguluka kwesivalo nofana ukugqwala kweshafu, okurholela ekuvuzeni kwebhoduluko nofana ukubhalelwa kwehlelo.

Amavalvu aPhakathi-Phezulu

• Imikhawulo yokugandeleleka/yokutjhisa: Yenzelwe amasistimu womfutho ophakathi ukuya phezulu (isib., PN16–PN40 / Iklasi 150–Iklasi 300) kanye namazinga womtjhiso abanzi (-30°C ukuya ku-200°C / -22°F ukuya ku-392°F).
• Ipilo yokuSebenza: Yenzelwe ukuthembeka kwesikhathi eside, ngempilo yomjikelezo edlula imisebenzi eyi-100,000. Amanye amamodeli wepremiyamu anikela ngewaranti yokuphila koke.
• Ukulawula ukuvuza: Iimvalo ezithuthukisiweko kanye namatjhafu wokuvikela ukuvuza kwehlisa ubungozi bokuvuza, okwenza bona zilungele ukusetjenziswa okuqakathekileko njengeenhlelo zegesi nofana ukuphatha uketshezi oluyingozi.

4. Iinsetjenziswa

Amavalvu aphasi

• Ilungele: Iinsetjenziswa ezingakaqakatheki, ezinengozi encani ezineemfuno ezisisekelo zokulawula ukugeleza, ezifana:
• Iinhlelo zokuphakelwa kwamanzi eendaweni zokuhlala
• Umsebenzi we-HVAC olula
• Ukuthelelela ngegandelelo eliphasi nofana ukukhipha amanzi
• Balekela ukusetjenziswa ngaphakathi: Amapayipi webubulo anegandelelo eliphezulu, iindaba ezibolako, nofana iindawo eziqakathekileko zokuphepha (isib., i-oli nerhasi, imithi).

Amavalvu aPhakathi-Phezulu

• Ilungele: Iinsetjenziswa ezifunako zebubulo nezokuthengisa, okufaka hlangana:
• Iintjalo zokusebenza ngamakhemikhali (uketshezi olubolako)
• Ukukhiqizwa kokudla neenselo (amazinga wokuhlanzeka)
• Ukukhiqizwa kwamandla (umtjhiso onokutjhisa okuphezulu)
• I-oli nerhasi (iimfuneko ezingaqhumi)
• Amazinga aqakathekileko: Kanengi aqinisekiswa yi-ISO, i-API, i-ASME, nofana i-ATEX ukuthobela imithetho yezokuphepha nekhwalithi yamazwe ngamazwe.

5. Iindleko nokugcinwa

Amavalvu aphasi

• Iindleko zokuthoma: Itjhiphile khulu (20-50% ngaphasi kwamamodeli aphakathi nendawo), okwenza bona akhange emaphrojekthini abucayi ngesabelomali.
• Ukutjheja: Iindleko eziphezulu zesikhathi eside ngebanga lokutjhugululwa kwesivalo kanengi, ukuthambisa ishafu, nofana ukulungisa ukugqwala.
• Ingozi yesikhathi sokuphumula: Kuvamise ukuhluleka okungalindelekileko, okurholela ekulahlekelweni mkhiqizo eendaweni zamabubulo.

Ukukhetha iValvu efaneleko (isib.I-TWS Valve)

• Okuphasi: Ilungele ukusetjenziswa kwesikhathi esifitjhani, okungakaqakatheki lapho iindleko ziyinto eqakathekileko.
• Phakathi-Phakathi-Phezulu: Tjala imali kizo ukuthembeka, ukuphepha, nokusebenza kwesikhathi eside eensetjenzisweni ezibudisi. Hlala ucabangela umhlobo wemidiya, ubujamo bokusebenza, kanye neemfuneko zokulandela lokha nawukhetha ivalvu.

 

Lokhu kuhlukaniswa kuveza bona kubayini amavalvu aphakathi nephezuluD371X-16Qzikhethwa emabubulweni aqakathekisa ukuphepha nokusebenza kuhle, ngesikhathi iinkhetho eziphasi zisebenzela iindingo ezisisekelo, eziqhutshwa ziindleko.

Isivalo esithambileko, ukusebenza okuqinilekoi-wafer butterfly valve, Ivalvu yevithamini ye-flange ephindwe kabili D34B1X-10Q, Ivalvu yesango, i-Y-strainer,I-wafer dual plate check valve,-Yenzelwe iinsombululo ze-Leak Fredd. Ukuvala okuqinileko, ukuthembeka okungalinganiswa, isazi sakho sokulawula ukugeleza.
