Isingeniso kumavalvu e-Butterfly
Ama-valve e-Butterfly
I-Butterfly valve iyi-valve ejikelezayo ejikelezayo, esetshenziselwa ukumisa, ukulawula, nokuqala ukugeleza.
Ama-valve ovemvane kulula futhi ayashesha ukuwavula. Ukuzungezisa okungu-90° kwesibambo kunikeza ukuvala okuphelele noma ukuvulwa kwevalvu. Ama-valve amakhulu e-Butterfly ngokuvamile afakwe okuthiwa yi-gearbox, lapho isondo lesandla ngamagiya lixhunywe esiqwini. Lokhu kwenza kube lula ukusebenza kwe-valve, kodwa ngezindleko zejubane.
Izinhlobo ze-Butterfly valves
Amavalve ovemvane anomzimba oyisiyingi omfushane, idiski eliyindilinga, izihlalo zensimbi-kuya-zensimbi noma ezithambile, ama-shaft bearings aphezulu naphansi, kanye nebhokisi lokugxusha. Ukwakhiwa komzimba we-Butterfly valve kuyahlukahluka. Idizayini evame ukusetshenziswa wuhlobo lwewafer olulingana phakathi kwama-flange amabili. Olunye uhlobo, i-lug wafer design, lubanjwe phakathi kwama-flange amabili ngamabhawodi ahlanganisa ama-flange amabili futhi adlule ezimbotsheni ze-valve engaphandle. Ama-valve e-Butterfly ayatholakala ngisho namaphethelo e-flanged, e-threaded kanye ne-butt, kodwa awavamile ukusetshenziswa.
Amavalvu ovemvane anezinzuzo eziningi ngaphezu kwesango, iglowubhu, ipulaki, namavalvu ebhola, ikakhulukazi ekufakweni kwamavalvu amakhulu. Ukonga ngesisindo, indawo, kanye nezindleko kuyizinzuzo ezisobala kakhulu. Izindleko zokunakekela ngokuvamile ziphansi ngoba kunenombolo encane yezingxenye ezihambayo futhi awekho amaphakethe okubamba uketshezi.
Amavalvu ovemvane afaneleka kakhulu ukuphatha ukugeleza okukhulu koketshezi noma amagesi ukucindezela okuphansi ngokulinganayo kanye nokubamba ama-slurries noma uketshezi olunenani elikhulu lezinto eziqinile ezimisiwe.
Ama-valve e-butterfly akhiwe ngomgomo we-damper yepayipi. Isici sokulawula ukugeleza siyidiski cishe enobubanzi obufanayo nobubanzi bangaphakathi bepayipi elihlangene, elizungeza ku-eksisi eqondile noma evundlile. Lapho i-disk ilele ngokuhambisana nokugijima kwamapayipi, i-valve ivuleka ngokugcwele. Lapho i-disk isondela endaweni ye-perpendicular, i-valve ivaliwe. Izindawo ezimaphakathi, ngezinhloso zokudonsa, zingavikelwa endaweni ngamadivayisi okukhiya isibambo.
I-Butterfly valve Seat Construction
Ukuma kokugeleza kwenziwa ngokuvaleka kwediski ye-valve esihlalweni esingaphakathi komngcele womzimba we-valve. Amavalvu amaningi e-Butterfly anesihlalo se-elastomeric lapho idiski ivaleka khona. Amanye ama-valve e-Butterfly anohlelo lwendandatho yophawu olusebenzisa i-clamp-ring ne-backing-ring eringini yerabha ebukhali. Lo mklamo uvimbela ukukhishwa kwama-O-rings.
Emiklamo yokuqala, idiski yensimbi yayisetshenziselwa ukuvala isihlalo sensimbi. Lolu hlelo aluzange lunikeze ukuvala okungavuzi, kodwa lunikeze ukuvala okwanele kwezinye izinhlelo zokusebenza (okungukuthi, izintambo zokusabalalisa amanzi).
Butterfly valve Ukwakhiwa Komzimba
Ukwakhiwa komzimba we-Butterfly valve kuyahlukahluka. Eyonga kakhulu uhlobo lwewafer olulingana phakathi kwama-flange amapayipi amabili. Olunye uhlobo, i-lug wafer design, lubanjwe phakathi kwamapayipi amabili ama-flange ngamabhawodi ahlanganisa ama-flange amabili futhi adlule ezimbotsheni ze-valve engaphandle. Ama-valve e-Butterfly ayatholakala aneziphetho ezivamile ezine-flanged zokubopha ama-flange amapayipi, kanye nokwakhiwa kokuphela okunentambo.
IDiski Yesihlalo kanye Nesiqu se-Butterfly valve
Isiqu nediski yevalvu yeButterfly yizicucu ezihlukene. Idiski inesithukuthezi ukwamukela isiqu. Izindlela ezimbili zisetshenziselwa ukuvikela idiski esiqwini ukuze idiski ijikeleze njengoba isiqu siphenduka. Ngendlela yokuqala, i-disk ibhorekile futhi ivikelekile esiqwini ngamabholithi noma izikhonkwane. Enye indlela ihlanganisa ukubhora idiski njengakuqala, bese ubumba isiqu esiphezulu ukuze silingane nesiqu esiyisikwele noma esimise okwe-hex. Le ndlela ivumela idiski ukuthi "intante" futhi ifune isikhungo sayo esihlalweni. Ukubekwa uphawu okufanayo kufeziwe futhi izibophelelo zesiqu zangaphandle ziyasuswa. Le ndlela yokuhlanganisa inenzuzo esimweni samadiski amboziwe kanye nasezinhlelweni ezigqwalile.
Ukuze i-disk ibanjwe endaweni efanele, isiqu kufanele sidlulele ngaphesheya kwediski futhi singene esihlahleni esingaphansi komzimba we-valve. Isihlahla esisodwa noma ezimbili ezifanayo ziseduze nengxenye engenhla yesiqu. Lezi zihlahlana kumele zikwazi ukumelana nabezindaba eziphathwayo noma zivalwe ukuze imithombo yezindaba ebolayo ingakwazi ukuthintana nazo.
Izigxivizo ze-stem zifezwa ngokupakisha ebhokisini elijwayelekile lokugxusha noma ngokusebenzisa izigxivizo ze-O-ring. Abanye abakhiqizi bamavalvu, ikakhulukazi labo abangochwepheshe ekuphatheni izinto ezonakalisayo, babeka i-stem seal ngaphakathi kwe-valve ukuze kungabikho lutho oluphathwa yi-valve olungathintana nesiqu se-valve. Uma kusetshenziswa ibhokisi lokugxusha noma i-O-ring yangaphandle, uketshezi oludlula kuvalvu luzohlangana nesiqu se-valve.
Ukusetshenziswa okujwayelekile kwamavalvu e-Butterfly
I-valve ye-Butterfly ingasetshenziswa ezinsizeni eziningi ezihlukene zoketshezi futhi isebenza kahle ekufakweni kodaka. Okulandelayo ezinye zezinhlelo ezijwayelekile zamavalvu eButterfly:
- Amanzi okupholisa, umoya, amagesi, ukuvikela umlilo njll.

Ama-Gaskets kanye nokufakwa kwama-Butterfly valves
NgoSepthemba 14, 2012 ngathola i-imeyili enala mazwi alandelayo:
Nginesiphakamiso kuwe engingacabangi ukuthi sibhekiswe kusayithi lakho, okuwukuchaza ukuthi hlobo luni lwe-gasket okufanele lusetshenziswe kumavalvu e-Butterfly ahlukene (Uhlobo E noma F) nokuthi hlobo luni lwe-flange elingumngane okufanele lisetshenziswe (RF noma FF), futhi nalapho i-gasket ingadingekile ngoba ama-valve athile e-Butterfly anama-gaskets abalulekile. Ngithole ukuthi kuvame ukudideka ngalolu daba.
Ukubuka okuhle ngakho-ke okulandelayo:
Imiyalo yokufaka evela kumnikezeli wama-Butterfly valves:
I-valve yakhelwe ukusetshenziswa phakathi kwazo zonke izinhlobo zamaFlange oBuso obuyiFlethi noma obuphakanyisiwe.
UNGASEBENZISI AMAGASEKI E-FLANGE.Idizayini ye-Butterfly valve ikhawulela isidingo sama-gaskets. Ukuze kufakwe kahle, isikhala phakathi kwama-flange kufanele sanele ukuvumela ukufakwa kwe-valve ngaphandle kokuphazamisa uphawu lwe-flange. Qaphela ukuthi unqenqema lokuvala idayikhi luhambisana nefulethi le-shaft. Zungezisa isiqu ukuze ubeke idiski ngaphakathi komzimba, beka i-valve phakathi kwama-flange bese uqinisa ngesandla amabhawodi.
VULA KANCANEi-valve iphikisana newashi ukuze uhlole imvume yediski eyanele.
BUYISELA IDISCI KU-10% OKUVULEKILE& weqa uqinise wonke amabhawodi, uphinde uhlole ukugunyazwa kwediski okwanele.
Akulungile
I-Disc isendaweni evaliwe futhi ama-Gaskets afakiwe
phakathi kwama-valve nama-mating flanges
Kulungile
Awekho ama-gaskets e-flange asetshenzisiwe kanye ne-Disc ku
cishe indawo evaliwe.
Omunye umyalo wokufaka ovela kumnikezeli wama-Butterfly valves:
ISEXWAYISO
Lawa ma-gasket alandelayo kufanele asetshenziselwe ukufaka ama-valve kumapayipi.
- Uhlobo lwe-Gasket
I-PTFE gasket eqinisiwe (i-gasket enejakhethi, i-Spiral Wound gasket noma i-Metal gasket ayikwazi ukufakwa.) - Ubukhulu be-Gasket
Ubukhulu be-gasket kufanele buhambisane ne-ASME B16.21. (Ubukhulu obuncane be-gasket ngu-3mm.)
Ama-valve awakwazi ukufakwa ukuze aqine. I-valve kufanele ifakwe ngokomcibisholo, ohlinzekwe ohlangothini lwe-flange yokufaka u-opharetha. Umcibisholo kufanele ukhombe ukusuka ohlangothini lwengcindezi ephakeme ukuya ohlangothini oluphansi lwe-valve endaweni evaliwe.
Ngakho-ke, kunconywa ukuthi ulandele imiyalelo yomhlinzeki we-Butterfly valve!
Ukugwema izinkinga nge-Butterfly valves
Iningi lazo zonke izinkinga ezinamavalve e-Butterfly ensimini zihlobene ngokuqondile nezinqubo zokufaka ezingezinhle. Ngenxa yalesi sizathu, kuwukuhlakanipha ukucabangela umkhuba ongcono kakhulu lapho ubeka umsebenzi wamapayipi futhi ufaka i-valve ngokwayo.
Isihlalo esikuvalvu yeButterfly ehlezi eqinile ngokuvamile sidlulela kubo bobabili ubuso bevalvu. Ngenxa yalokho, awekho ama-gasket adingekayo njengoba lezi zihlalo zisebenza njenge-gasket. Impahla yesihlalo edlula ebusweni iyacindezelwa ngesikhathi sokufakwa futhi igeleza iqonde maphakathi nesihlalo sevalvu. Noma iluphi ushintsho kulokhu kucushwa ngenxa yokufakwa okungafanele luthinta ngokuqondile isilinganiso sokucindezela kanye nama-torque okuhlala/okweqa.
Ngokungafani nezinhlobo eziningi zama-valve, idiski ye-Butterfly valve idlulela ngalé kobuso bomzimba we-valve kuma-engeli anikeziwe wokuvula (ake athi, 30° noma ngaphezulu) lapho efakwe phakathi kwama-flange. Ngakho-ke, kubaluleke kakhulu ngaphambi kokufakwa ukuqinisekisa ukuthi i-disc iyakwazi ukuguqula ngokukhululekile futhi ifake ama-flanges kanye nomsebenzi wepayipi.
Ukuthunyelwa kanye Nesitoreji
- Beka ama-disc ngo-10% avuliwe ukuze angagxiliwe.
- Ubuso bevalvu ngayinye kufanele bumbozwe ukuvimbela ukulimala ebusweni besihlalo, i-disc edge, noma ingaphakathi levalvu.
- Gcina endlini, okungcono ngamazinga okushisa aphakathi kuka-5°C no-30°C.
- Vula futhi uvale amavalvu njalo ezinyangeni ezi-3.
- Umkhumbi kanye nama-valve esitolo ukuze kungabikho mithwalo esindayo efakwa emizimbeni.
Indawo yevalvu
- Amavalvu ovemvane kufanele afakwe uma kungenzeka okungenani amadayimitha amapayipi ayi-6 avela kwezinye izakhi zomugqa, okungukuthi izindololwane, amaphampu, amavalvu, njll. Ngezinye izikhathi lokhu akwenzeki, kodwa kubalulekile ukufinyelela ibanga elide ngangokunokwenzeka.
- Lapho i-valve ye-Butterfly ixhunywe ku-valve yokuhlola noma iphampu, gcina isikhala esanele phakathi kwazo ukuze uqinisekise ukuthi idiski ayiphazamisi impahla eseduze.
I-Valve Orientation
Njengomthetho wesithupha, amavalvu e-Butterfly afakwa nesiqu endaweni eqondile ne-actuator efakwe phezulu ngokuqondile ngaphezu kwayo, nokho, kukhona izinhlelo zokusebenza lapho isiqu kufanele sivundlile. Ifayela elithi .pdf elingezansi likutshela ukuthi kungani isiqu ngezikhathi ezithile kufanele simiswe sivundlile.

Izinqubo zokufaka
- Qinisekisa ukuthi ipayipi nobuso be-flange buhlanzekile. Noma iyiphi impahla yangaphandle efana nokufiyilwa kwensimbi, isikali sepayipi, i-slag yokushisela, izinduku zokushisela, njll. kungakhawulela ukunyakaza kwediski noma kulimaze idiski noma isihlalo.
- Ama-gaskets awadingeki kuma-valve ahlezi aqinile ngoba anwebeka ebusweni bobubili be-valve.
- Qondanisa umsebenzi wepayipi, futhi usakaze ama-flanges ngokwanele ukuvumela umzimba we-valve ukuthi ufakwe kalula phakathi kwama-flange ngaphandle kokuxhumana nama-flange amapayipi.
- Hlola ukuthi idiski ye-valve isethwe ukuthi ivuleke cishe ngo-10% ukuze ingaminyanisi endaweni yokuhlala ngokugcwele.
- Faka i-valve phakathi kwama-flange njengoba kukhonjisiwe, uqaphele ukuthi ungalimazi ubuso besihlalo. Ngaso sonke isikhathi phakamisa ivalvu ngezimbobo zendawo noma ngokusebenzisa isihlilingi senayiloni entanyeni noma emzimbeni. Ungalokothi uphakamise i-valve nge-actuator noma i-opharetha efakwe ku-valve.
- Beka i-valve phakathi kwama-flanges, uyibeke phakathi, faka ama-bolts futhi uwaqinise ngesandla. Vula ngokucophelela i-disc, uqinisekise ukuthi i-disc ayixhumani nengaphakathi lamapayipi aseduze.
- Vala kancane kancane i-valve disc ukuze uqinisekise ukuphuma konqenqema lwe-disc kusukela ku-flange yepayipi eseduze.
- Vula ngokugcwele i-disc bese uqinisa wonke ama-flange bolt njengoba kukhonjisiwe.
- Phinda ukuvala okugcwele kokujikeleza okugcwele kwe-disc ukuze uqinisekise ukucaciswa okufanele.
