isimiso sokusebenza
A ivalvu yebhabhathaneuhlobo lwevalvu olulungisa ukugeleza kwe-medium ngokuyivula noma ukuyivala ngokujika emuva naphambili cishe ngama-degrees angu-90. Ngaphezu komklamo wayo oqondile, usayizi omncane, isisindo esincane, ukusetshenziswa kwezinto eziphansi, ukufakwa okulula, i-torque ephansi yokushayela, kanye nokusebenza okusheshayo,ivalvu yebhabhathanefuthi isebenza kahle ngokwemigomo yokulawula ukugeleza ngenkathi futhi inezimfanelo ezinhle zokuvala nokuvala. Enye yezinhlobo ezisheshayo zevalvu. Ukusetshenziswa kweamavalvu ebhabhathanekuvamile.

Ukusetshenziswa kwayo kuyaqhubeka nokuhlukahluka nokwanda, futhi kushintshela ekushiseni okuphezulu, umfutho ophezulu, ububanzi obukhulu, ukuvala okuphezulu, impilo ende, izici zokulungisa ezivelele, kanye nemisebenzi eminingi yevalvu. Manje inezinga eliphezulu lokuthembeka kanye nezinye izici zokusebenza.

Ukusebenza kwamavalvu e-butterfly kuthuthukile ngenxa yokusetshenziswa kwerabha yokwenziwa engamelani namakhemikhali. Njengoba irabha yokwenziwa inezimfanelo zokumelana nokugqwala, ukumelana nokuguguleka, usayizi ozinzile, ukuqina okuhle, ukwakheka okulula, kanye nezindleko eziphansi, irabha yokwenziwa enezakhiwo ezahlukahlukene ingakhethwa ngokuhambisana nezidingo ezahlukene zokusetshenziswa ukuze kwaneliswe izimo zokusebenza zamavalvu e-butterfly.

Njengoba i-polytetrafluoroethylene (PTFE) inokumelana okunamandla nokugqwala, ukusebenza okuzinzile, ukumelana nokuguga, i-coefficient ephansi yokungqubuzana, ukulula kokuma, kanye nokuqina kosayizi, ukusebenza kwayo konke kungathuthukiswa ngokugcwalisa nokwengeza izinto ezifanele ukuze kufezwe amandla nokungqubuzana okungcono. Irabha yokwenziwa inezinkinga ezithile, kodwa izinto zokuvala amavalvu e-butterfly ezine-coefficient ephansi ziyawazungeza. Ukuze kuthuthukiswe ukusebenza kwamavalvu e-butterfly, izinto ze-polymer ezinama-molecule amaningi, njenge-polytetrafluoroethylene, kanye nezinto zazo eziguquliwe zokugcwalisa ziye zasetshenziswa kabanzi. Manje isithuthukisiwe, futhi ivalvu ye-butterfly ikhiqizwe ngebanga lokushisa elikhulu kanye nengcindezi, ukusebenza kokuvala okuthembekile, kanye nokuphila isikhathi eside okuwusizo.

Amavalvu ebhabhathane avaliwe ngensimbi athuthuke kakhulu ukuze kuhlangatshezwane nezidingo zezicelo zezimboni ezifana nokushisa okuphezulu nokuphansi, ukuguguleka okunamandla, kanye nokuphila isikhathi eside. Amavalvu ebhabhathane avaliwe ngensimbi asetshenziswe kakhulu emikhakheni yezimboni efana nokushisa okuphezulu nokuphansi, ukuguguleka okunamandla, kanye nokuphila isikhathi eside ngenxa yokusetshenziswa kokumelana nokushisa okuphezulu, ukumelana nokushisa okuphansi, ukumelana nokugqwala okunamandla, ukumelana nokuguguleka okunamandla, kanye nezinto ze-alloy ezinamandla aphezulu. Ukuze kuthuthukiswe ubuchwepheshe bevalvu yebhabhathane, ububanzi obukhulu (9–750mm), umfutho ophezulu (42.0MPa), kanye nobubanzi bokushisa obubanzi (-196–606°C) amavalvu ebhabhathane aqala ukuvela.

Ivalvu yebhabhathane inokumelana okuncane kokugeleza uma ivuliwe ngokuphelele. Amavalvu ebhabhathane avame ukusetshenziswa emkhakheni wokulawula ububanzi obukhulu ngoba ayakwazi ukulawula ukugeleza okubucayi ezindaweni eziphakathi kuka-15° no-70°.

Iningi lama-valve e-butterfly lingasetshenziswa nge-media equkethe izinhlayiya eziqinile ezilengayo njengoba ipuleti le-butterfly lihamba ngendlela yokusula. Lingasetshenziswa futhi kwi-media ene-granular kanye ne-powdery, kuye ngamandla e-seal.

Amavalvu ebhabhathane ayasiza ekulawuleni ukugeleza. Lapho ukhetha ivalvu yebhabhathane, kubalulekile ukucabangela ngokugcwele umthelela wokulahlekelwa yingcindezi ohlelweni lwepayipi kanye namandla epuleti lebhabhathane ukuze limelane nengcindezi yendawo yomzila wepayipi lapho ivaliwe ngoba ukulahlekelwa yingcindezi yevalvu yebhabhathane epayipini kukhulu kakhulu, cishe kuphindwe kathathu kunevalvu yesango. Izinga lokushisa lokusebenza lezinto zesihlalo esinwebekayo emazingeni okushisa aphezulu nalo kufanele licatshangelwe.

Ivalvu yebhabhathane inesakhiwo esifushane kanye nokuphakama okuphansi. Iyavula futhi ivale ngokushesha futhi inezakhiwo ezinhle zokulawula uketshezi. Ukwenza amavalvu amakhulu kufaneleka kakhulu ekwakhiweni kwevalvu yebhabhathane. Isinyathelo esibaluleke kakhulu ekukhetheni ivalvu yebhabhathane ezosebenza kahle nangempumelelo uma isetshenziswa ukulawula ukugeleza kwamanzi ukukhetha uhlobo olufanele kanye nencazelo.

Amavalvu e-Butterfly avame ukwelulekwa ukuthi asetshenziswe ekucindezelweni, ekulawuleni ukulawula, kanye nasezindaweni zodaka lapho kudingeka khona ubude obufushane besakhiwo, isivinini sokuvula nokuvala okusheshayo, kanye nokunqanyulwa kwengcindezi ephansi (umehluko omncane wengcindezi). Amavalvu e-Butterfly angasetshenziswa ngezindawo zokucindezela ezihudulayo, iziteshi ezinobubanzi obuncishisiwe, umsindo ophansi, ukugoba kanye nokuhwamuka, inani elincane lokuvuza komoya, kanye nokulungiswa kwesikhundla esiphindwe kabili. Ukulungiswa kwe-throttle lapho usebenza ngaphansi kwezimo ezingavamile, njengalapho uvala ngokuqinile, ukuguguleka okukhulu, amazinga okushisa aphansi kakhulu, njalo njalo.
