Umehluko kanye nokusetshenziswa kwama-valve evemvane e-eccentric ephindwe kabili kanye ne-eccentric kathathu

Ama-valve evemvane ane-eccentric ephindwe kabili kanye nama-valve uvemvane ane-eccentric kathathu asetshenziswa kakhulu izinhlobo zamavalvu emkhakheni wezimboni. Adlala indima ebalulekile ekulawuleni uketshezi futhi asetshenziswa ezimbonini ezihlukahlukene ezifana ne-petroleum, amakhemikhali, ukucubungula ukudla, nokuhlanza amanzi. Ukwazi umehluko phakathi kwabo kubalulekile ekukhetheni okulungile nokusetshenziswa kwe-valve efanele.

Umehluko wedizayini yesakhiwo: Idizayini ye-valve uvemvane ene-eccentric ephindwe kabili ihlanganisa ama-eccentric shafts amabili, eyodwa yawo etholakala maphakathi nepuleti lovemvane kanti enye itholakala kumngcele wepuleti lovemvane. Lesi sakhiwo senza i-butterfly plate inciphise ukungqubuzana lapho ivula futhi ivala, ngaleyo ndlela inciphise amandla okusebenza. Ngokuphambene, umklamo we-valve uvemvane we-eccentric kathathu wengeza i-eccentric shaft yesithathu epuleti lovemvane, ukuze ipuleti uvemvane lihlukaniswe ngokuphelele neringi yesihlalo lapho livaliwe, ngaleyo ndlela kuncishiswe ingcindezi yokuvala futhi kuthuthukiswe ukusebenza kokuvala.

Umehluko esimisweni sokusebenza: Ivalve uvemvane eccentric kabili ilawula ukugeleza koketshezi ngokuzungezisa ipuleti lovemvane. Lapho ipuleti uvemvane livulwe ngokugcwele, kwakheka umzila omkhulu phakathi kwepuleti uvemvane nendandatho yokuhlala, ukuze uketshezi ludlule ngokushelela. Ngokuphambene nalokho, lapho ipuleti le-butterfly livaliwe, isiteshi sizovalwa ngokuphelele, sivimbele ukudlula kwamanzi.

Isimiso sokusebenza se-valve uvemvane eccentric kathathu siyefana naleyo ye-valve uvemvane ene-eccentric ephindwe kabili, kodwa ilungisa ukuma kwepuleti lovemvane ngokusebenzisa i-eccentric shaft yepuleti lovemvane ukuze likwazi ukuphuma ngokuphelele eringini yesihlalo lapho likhona. ivaliwe. Lo mklamo unganciphisa ukugqokwa kwendawo yokuvala, yelule impilo yesevisi ye-valve, futhi uthuthukise ukusebenza kokuvala nokumelana nokucindezela okuphezulu.Umehluko ezimeni zohlelo lokusebenza: Ama-valve butterfly eccentric kabili avame ukusetshenziswa ekucindezelweni okuphakathi nokuphansi kanye noketshezi olujwayelekile. lawula izinhlelo zokusebenza. Isakhiwo sayo esilula nokusebenza okuguquguqukayo kulungele izikhathi ezidinga ukuvulwa nokuvala njalo. Isibonelo, i-valve ivame ukusetshenziselwa izinhlelo zokuhlinzeka ngamanzi kanye ne-drainage, ukwelashwa kwamanzi angcolile kanye nezinhlelo zokupholisa umoya, njll.

Ngokuphambene, i-valve ye-butterfly eccentric kathathu ifanele ukucindezela okuphezulu nezimo zokusebenza ezinzima kakhulu. Ngenxa yokusebenza kahle kokuvalwa kwayo kanye nokumelana nokucindezela okukhulu, ivame ukusetshenziswa emkhakheni we-petroleum, imboni yamakhemikhali, igesi yemvelo kanye nokukhiqiza amandla ashisayo. Ngaphezu kwalokho, i-valve ye-butterfly eccentric kathathu nayo ifanelekile ekulawuleni imidiya edlayo kanye nemidiya yokushisa ephezulu.

Isiphetho: Kunomehluko osobala phakathi kwe-double eccentric butterfly valve kanye ne-triple eccentric butterfly valve ekwakhiweni kwesakhiwo, isimiso sokusebenza kanye nezimo zokusetshenziswa. Amavalvu ovemvane ane-eccentric kabili afanele umfutho ophakathi nendawo nophansi kanye nokulawula uketshezi olujwayelekile, kuyilapho amavalvu uvemvane eccentric kathathu afanele ukucindezela okuphezulu nezimo zesevisi ezinzima kakhulu. Ukukhetha kahle kanye nokusetshenziswa kwama-valve afanelekile kubalulekile ukuze kuqinisekiswe ukusebenza kahle nokuphepha kohlelo. Ngakho-ke, ekusetshenzisweni okusebenzayo, kuyisinqumo esibaluleke kakhulu ukukhetha uhlobo lwe-valve olufaneleka kakhulu ngokwezidingo ezithile kanye nezimo zokusebenza.
