I-Butterfly Valve Isingeniso

Isingeniso:

Ivalve uvemvaneuvela emndenini wamavalvu okuthiwaama-valve e-quarter-turn.Lapho isebenza, i-valve ivuleka ngokugcwele noma ivaliwe lapho i-disc izungeziswa ngokujika kwekota.“Uvemvane” yidiski yensimbi efakwe endukwini.Lapho i-valve ivaliwe, i-disc ivuliwe ukuze ivimbe ngokuphelele umgwaqo.Uma i-valve ivuleke ngokugcwele, i-disc ijikeleziswa ikota ukuze ivumele ukudlula okungavinjelwe koketshezi.I-valve ingase ivuleke kancane kancane ukuze i-throttle flow.

Kunezinhlobo ezahlukene zamavalvu ovemvane, ngalinye lilungiselwe izingcindezi ezihlukene kanye nokusetshenziswa okuhlukile.I-valve uvemvane oyiziro-offset, esebenzisa ukuguquguquka kwenjoloba, inezinga lokucindezela eliphansi kakhulu.I-valve ye-butterfly ye-double offset esebenza kahle kakhulu, esetshenziswa ezinhlelweni zokucindezela okuphezulu kancane, isuswa emgqeni ophakathi nendawo yesihlalo sediski kanye ne-body seal (i-offset one), kanye nomugqa ophakathi we-bore (offset two).Lokhu kudala isenzo se-cam ngesikhathi sokusebenza sokuphakamisa isihlalo ngaphandle kwesigxivizo okuholela ekungqubuzaneni okuncane kunalokho okudalwe kumklamo we-zero offset futhi kunciphisa ukuthambekela kwaso kokugqoka.I-valve efaneleka kakhulu kumasistimu okucindezela okuphezulu ivalve yevemvane ephindwe kathathu.Kule valvu i-axis yokuxhumana yesihlalo sediski iyasuswa, esebenza ukuqeda ukuxhumana okuslayidayo phakathi kwediski nesihlalo.Endabeni yama-valve amathathu e-offset isihlalo senziwe ngensimbi ukuze sikwazi umshini njengokuthola ukuvala okuqinile kwebhamuza lapho uthintana nediski.

Izinhlobo

1. Ama-valve evemvane agxilile- lolu hlobo lwe-valve lunesihlalo serabha esiqinile esine-disc yensimbi.
2. Ama-valve uvemvane ane-eccentric kabili(ama-butterfly valves asebenza kahle kakhulu noma ama-butterfly ama-double-offset) - uhlobo oluhlukile lwezinto ezisetshenziselwa isihlalo kanye nediski.
3. Ama-valve uvemvane ane-triply-eccentric(ama-valve e-butterfly e-triple-offset) - izihlalo zingama-laminated noma izihlalo eziqinile zensimbi.

Ama-valve e-butterfly yesitayela se-wafer

II-valve ye-butterfly yesitayela se-waferyakhelwe ukugcina uphawu oluphikisana nomehluko wengcindezi e-bi-directional ukuvimbela noma yikuphi ukugeleza emuva kumasistimu aklanyelwe ukugeleza okukodwa.Ifeza lokhu ngophawu oluqinile oluqinile;okungukuthi, i-gasket, i-o-ring, ukunemba ngomshini, kanye nobuso bevalvu eyisicaba emaceleni akhuphuka nomfula kanye naphansi komfula.

I-valve ye-butterfly yesitayela se-Lug

Ama-valve wesitayela se-Lugbabe nokufaka imicu ezinhlangothini zombili zomzimba we-valve.Lokhu kuzivumela ukuthi zifakwe ohlelweni kusetshenziswa amasethi amabili amabhawodi futhi awekho amantongomane.I-valve ifakwe phakathi kwama-flange amabili kusetshenziswa isethi ehlukile yamabhawudi ku-flange ngayinye.Lokhu kusetha kuvumela noma yiluphi uhlangothi lwesistimu yamapayipi ukuthi lunqanyulwe ngaphandle kokuphazamisa olunye uhlangothi.

Ivalvu uvemvane wesitayela se-lug esetshenziswa enkonzweni yokuphela kwento ngokuvamile inesilinganiso sokucindezela esincishisiwe.Isibonelo, ivalve yovemvane yesitayela se-lug efakwe phakathi kwama-flange amabili inesilinganiso sokucindezela esingu-1,000 kPa (150 psi).I-valve efanayo efakwe nge-flange eyodwa, kusevisi yokugcina efile, inesilinganiso esingu-520 kPa (75 psi).Ama-valve ahlanganisiwe amelana ngokwedlulele namakhemikhali nezincibilikisi futhi angakwazi ukumelana nezinga lokushisa elifinyelela ku-200 °C, okulenza libe yisixazululo esisebenza ngezindlela eziningi.

Sebenzisa embonini

Ezimbonini zemithi, amakhemikhali, nezokudla, ivalve uvemvane isetshenziswa ukuphazamisa ukugeleza komkhiqizo (okuqinile, okuwuketshezi, igesi) ngaphakathi kwenqubo.Amavalvu asetshenziswa kulezi zimboni ngokuvamile akhiqizwa ngokweziqondiso ze-cGMP (umkhuba wamanje wokukhiqiza omuhle).Amavalvu ovemvane ngokuvamile ashintsha amavalvu ebhola ezimbonini eziningi, ikakhulukazi i-petroleum, ngenxa yezindleko eziphansi kanye nokufaka kalula, kodwa amapayipi anamavemvane awakwazi 'ukucwiliswa' ukuze ahlanzwe.
