Umthelela Wezinga Lokushisa Nokucindezela Ku-Butterfly Valve Performance
Amakhasimende amaningi asithumelela imibuzo, futhi sizophendula sibacela ukuthi banikeze uhlobo oluphakathi, izinga lokushisa eliphakathi nokucindezela, ngoba lokhu akuthinti kuphela intengo ye-butterfly valve, kodwa futhi kuyisici esiyinhloko esithinta ukusebenza kwe-valve butterfly. Umthelela wabo ku-valve uvemvane uyinkimbinkimbi futhi ubanzi.
1. Umthelela Wezinga Lokushisa Ekusebenzeni Kwevaluvu Yevemvane:
1.1. Izinto ezibonakalayo
Ezindaweni ezinokushisa okuphezulu, izinto ezifana nomzimba we-butterfly valve kanye ne-valve stem zidinga ukumelana nokushisa okuhle, ngaphandle kwalokho amandla nobulukhuni kuzothinteka. Endaweni yokushisa ephansi, i-valve yomzimba izoba brittle. Ngakho-ke, izinto ze-alloy ezikwazi ukumelana nokushisa kumele zikhethelwe izindawo ezinokushisa okuphezulu, futhi izinto ezinokuqina okuhle kokumelana nokubanda kufanele zikhethelwe izindawo ezisezingeni eliphansi lokushisa.
Sithini izinga lokushisa lomzimba wevalvu uvemvane?
I-Ductile iron butterfly valve: -10 ℃ kuya ku-200 ℃
I-WCB butterfly valve: -29℃ ukuya ku-425℃.
SS uvemvane valveUkushisa: -196 ℃ kuya ku-800 ℃.
I-valve uvemvane LCBUkushisa: -46 ℃ kuya ku-340 ℃.
1.2. Ukuvala Ukusebenza
Izinga lokushisa eliphakeme lizokwenza ukuthi isihlalo se-valve ethambile, indandatho yokuvala, njll. ithambe, yande futhi ikhubazeke, inciphise umphumela wokuvala; kuyilapho izinga lokushisa eliphansi lingase lukhuni impahla yokuvala, okuholela ekwehleni kokusebenza kokuvala. Ngakho-ke, ukuze kuqinisekiswe ukusebenza kokuvala ezindaweni zokushisa eziphakeme noma eziphansi, kuyadingeka ukukhetha izinto zokuvala ezifanele izindawo zokushisa eziphezulu.
Okulandelayo yizinga lokushisa lokusebenza kwesihlalo se-valve ethambile.
• I-EPDM -46℃ – 135℃ I-Anti-aging
• I-NBR -23℃-93℃ Imelana Nowoyela
• I-PTFE -20℃-180℃ I-anti-corrosion nemidiya yamakhemikhali
• I-VITON -23℃ - 200℃ I-Anti-corrosion, ukumelana nokushisa okuphezulu
• I-Silica -55℃ -180℃ Ukumelana nokushisa okuphezulu
• I-NR -20℃ - 85℃ Ukunwebeka okuphezulu
• CR -29℃ – 99℃ I-Wear-resistant, anti-aging
1.3. Amandla esakhiwo
Ngikholwa ukuthi wonke umuntu uzwile ngomqondo obizwa ngokuthi "ukunwetshwa okushisayo nokufinyela". Ukushintsha kwezinga lokushisa kuzodala ukuwohloka kokucindezeleka okushisayo noma imifantu emalunga namavalvu evemvane, amabhawudi nezinye izingxenye. Ngakho-ke, lapho uklama futhi ufaka ama-valve e-butterfly, kuyadingeka ukucabangela umthelela wokushintsha kwezinga lokushisa esakhiweni se-butterfly valve, futhi uthathe izinyathelo ezihambisanayo zokunciphisa umthelela wokwandisa nokunciphisa okushisayo.
1.4. Izinguquko ezicini zokugeleza
Ukushintsha kwezinga lokushisa kungase kuthinte ukuminyana kanye ne-viscosity ye-fluid medium, ngaleyo ndlela kuthinte izici zokugeleza kwe-valve uvemvane. Ekusetshenzisweni okungokoqobo, umthelela wokushintsha kwezinga lokushisa ezicini zokugeleza udinga ukucatshangelwa ukuze kuqinisekiswe ukuthi i-valve uvemvane ingahlangabezana nezidingo zokulawula ukugeleza ngaphansi kwezimo ezihlukahlukene zokushisa.
2. Umthelela Wengcindezi Ekusebenzeni Kwevalve Yevemvane
2.1. Ukusebenza kokuvala
Lapho umfutho we-fluid medium ukhuphuka, i-valve uvemvane idinga ukumelana nomehluko omkhulu wengcindezi. Ezindaweni ezinomfutho ophezulu, ama-valve ovemvane kudingeka abe nokusebenza okwanele kokuvala ukuze kuqinisekiswe ukuthi ukuvuza akwenzeki lapho i-valve ivaliwe. Ngakho-ke, indawo yokuvala yama-valve emvemvane ngokuvamile yenziwa nge-carbide nensimbi engagqwali ukuze kuqinisekiswe amandla nokugqoka ukumelana nendawo yokuvala.
2.2. Amandla esakhiwo
I-Butterfly valve Endaweni enengcindezi ephezulu, i-valve yovemvane idinga ukumelana nokucindezela okukhulu, ngakho-ke impahla kanye nesakhiwo se-valve uvemvane kumele kube namandla anele kanye nokuqina. Isakhiwo se-valve uvemvane ngokuvamile sihlanganisa umzimba we-valve, i-valve plate, i-valve stem, isihlalo se-valve nezinye izingxenye. Amandla anganele anoma iyiphi yalezi zingxenye angabangela ukuthi i-valve uvemvane ihluleke ngaphansi kwengcindezi ephezulu. Ngakho-ke, kuyadingeka ukucabangela ithonya lokucindezela lapho uklama isakhiwo se-valve butterfly futhi wamukele izinto ezinengqondo kanye namafomu esakhiwo.
2.3. Ukusebenza kwe-valve
Indawo enengcindezi ephezulu ingase ithinte i-torque ye-valve uvemvane, futhi i-valve uvemvane ingase idinge amandla amakhulu okusebenza ukuze ivule noma ivale. Ngakho-ke, uma i-valve ye-butterfly ingaphansi kwengcindezi ephezulu, kungcono ukhethe ama-actuator kagesi, i-pneumatic nezinye.
2.4. Ingozi yokuvuza
Ezimweni ezinengcindezi ephezulu, ingozi yokuvuza iyanda. Ngisho nokuvuza okuncane kungaholela ekumoshweni kwamandla nasezingozini zokuphepha. Ngakho-ke, kuyadingeka ukuqinisekisa ukuthi i-valve ye-butterfly inomsebenzi omuhle wokuvala ezindaweni ezinengcindezi ephezulu ukunciphisa ingozi yokuvuza.
2.5. Ukumelana nokugeleza okumaphakathi
Ukumelana nokugeleza kuyinkomba ebalulekile yokusebenza kwe-valve. Kuyini ukumelana nokugeleza? Isho ukumelana okutholwa uketshezi oludlula kuvalvu. Ngaphansi kwengcindezi ephezulu, ingcindezi ye-medium ku-valve plate iyakhuphuka, idinga ukuthi i-valve uvemvane ibe namandla okugeleza aphezulu. Ngalesi sikhathi, i-valve ye-butterfly idinga ukuthuthukisa ukusebenza kokugeleza nokunciphisa ukumelana nokugeleza.
Ngokuvamile, umthelela wokushisa nokucindezela ekusebenzeni kwe-valve ye-butterfly kunezici eziningi, okuhlanganisa ukusebenza kokuvala, amandla esakhiwo, ukusebenza kwe-valve uvemvane, njll. Ukuze kuqinisekiswe ukuthi i-valve uvemvane ingasebenza ngokujwayelekile ngaphansi kwezimo ezihlukene zokusebenza, kuyadingeka ukukhetha izinto ezifanele, ukwakheka kwesakhiwo nokubeka uphawu, futhi uthathe izinyathelo ezihambisanayo ukuze ubhekane nezinguquko zokushisa nokucindezela.
