2.1 Ulwakhiwo
Ingqungquthela yokuvala (i-butterfly plate) ye-valve ye-butterfly iphakathi phakathi, kwaye impembelelo yayo ekuchaseni ukuhamba kufuneka ithathelwe ingqalelo kuyilo.

Ingqungquthela yokuvala (i-butterfly plate) ye-valve ye-butterfly iphakathi phakathi, kwaye impembelelo yayo ekuchaseni ukuhamba kufuneka ithathelwe ingqalelo kuyilo.
Ngokubhekiselele kwisakhiwo sepleyiti yebhabhathane yevalve yebhabhathane enobubanzi obukhulu, iAWWA C504 (iAmerican Water Supply Engineering Association Standard) ichaza ukuba ipleyiti yebhabhathane ayifanele ibe neembambo ezinqamlezileyo, kwaye ubukhulu bayo bungabi ngaphezu kwama-2.25 ububanzi isiqu sevalvu.
Umgangatho ongenayo amanzi kunye nomgangatho wamanzi we-butterfly plate kufuneka ulungelelaniswe.
Izikrufu zangaphakathi azikwazi ukuphuma ngaphandle kwepleyiti yebhabhathane, ukuze unganyusi indawo ejongene namanzi.
2.2 Irabha etywiniweyo

Izikrufu zangaphakathi azikwazi ukuphuma ngaphandle kwepleyiti yebhabhathane, ukuze unganyusi indawo ejongene namanzi.
2.2 Irabha etywiniweyo
Ngamanye amaxesha ubomi benkonzo ye-rubber butterfly valve bufutshane, ehambelana nomgangatho we-rubber kunye nobubanzi bendawo yokutywinwa.Umsesane wokutywina we-valve ye-butterfly etywiniweyo kufuneka yenziwe ngezinto eziphezulu zerubha, kwaye imigaqo yenkqubo kufuneka ilandelwe ngexesha lokubunjwa koxinzelelo.Ukushisa kwe-vulcanization akufanele kunyuswe ngokungqongqo, kwaye ixesha lingancitshiswa, ngaphandle koko kuya kubangela ukuba i-ring yokutywina iguge kwaye iqhekeke ngokulula.Indawo yokutywina yentsimbi ehambelana nendandatho yokutywina yerabha kufuneka ibe nobubanzi obaneleyo, ngaphandle koko i-rubber yokutywina i-rubber ayilula ukuba ifakwe.Ukongeza, imilo kunye nokunyamezelana kwesikhundla, i-symmetry, ukuchaneka, ukugudiswa, kunye ne-elasticity yeringi yokutywina ye-valve yomzimba kunye ne-butterfly plate nayo ichaphazela ubomi benkonzo yeringi yokutywinwa kwerabha.
2.2 Ukuqina
Ukuqina ngumba obalulekileyo ekuyilweni kweevalve zebhabhathane, ezihambelana nezinto ezifana neepleyiti zebhabhathane, i-valve shafts kunye nokudibanisa.
Ukuqina ngumba obalulekileyo ekuyilweni kweevalve zebhabhathane, ezihambelana nezinto ezifana neepleyiti zebhabhathane, i-valve shafts kunye nokudibanisa.
(1) Ubungakanani beshafu yevalvu Ubungakanani beshafu yevalvu buchazwe kwi-AWWA C504.Ukuba ubungakanani be-valve shaft abuhlangabezani neemfuno, kunokubakho ukuqina okungonelanga, ukuvuza kwe-reverse seal, kunye ne-torque enkulu yokuvula.Ukuqina kwe-shaft kuhambelana ne-1 / EI, oko kukuthi, ukuphucula ukuqina kunye nokunciphisa ingxaki yokuguqulwa, kufuneka siqale ngokunyusa i-EI.I-E yimodyuli yokunwebeka.Ngokuqhelekileyo, umehluko wensimbi awukho mkhulu, kwaye izinto ezikhethiweyo zinempembelelo encinci ekuqineni.Ndingumzuzu we-inertia kwaye inxulumene nobukhulu becandelo le-shaft.Ubungakanani be-valve shaft ngokuqhelekileyo bubalwa ngokuhambelana nokugoba kunye nokunyanzeliswa.Ayinxulumene kuphela ne-torque, kodwa inxulumene kakhulu nomzuzu wokugoba.Ngokukodwa, umzuzu wokugoba wevalve yebhabhathane enobubanzi obukhulu mkhulu kunetorque.
(2) Ukulungelelaniswa komngxuma we-shaft Uhlobo oludala lwe-AWWA C504 lumisela ukuba i-valve yevalve ye-butterfly shaft yi-shaft ethe tye.Emva kwenguqulelo ka-1980, kwacetywa ukuba yenziwe ibe ziishafu ezimbini ezimfutshane.Ngokutsho kwe-AWWA C504 kunye ne-GB12238, ubude obufakwe kwi-shaft kunye nomngxuma kufuneka ube yi-1.5d.Umsantsa (ixabiso le-C) phakathi komphetho womzimba wevalve kunye nesiphelo senkxaso yepleyiti yebhabhathane kwidimension ye-axial yevalve yebhabhathane yaseJapan ichaziwe, ehambelana ngokubanzi nobungakanani bobubanzi, obuphakathi kwe-25 kunye ne-45mm. , oko kukunciphisa umgama phakathi kweenkxaso ze-shaft (ixabiso le-C), ngaloo ndlela ukunciphisa umzuzu wokugoba kunye nokuguqulwa kwe-shaft.
3Ngamafutshane, kukunyusa umzuzu we-inertia yecandelo ukunyusa ukuqina.
4Ngokuqhelekileyo, kukho iimbambo zeringi kunye neentambo ezinqamlekileyo.Enyanisweni, iimbambo zomnqamlezo zandisa kuphela ukuzinza kwaye akufanele zibe zininzi kakhulu.Ezona ziphambili ziimbambo zeringi.Ukuba unokongeza i-∩-shaped ribs, kuya kuba luncedo ngakumbi ekuqineni, kodwa kukho ingxaki yokwenziwa kakubi.
2.3 Iibheringi zokuzithambisa
Ininzi okanye yonke ingcinezelo ephakathi kwi-butterfly plate (reverse) idluliselwa kwi-bearing ngokusebenzisa i-shaft, ngoko ukuthwala kudlala indima ebaluleke kakhulu.Ezinye iivalvu zebhabhathane zasemzini zikhaphukhaphu kwaye ziluncedo, kwaye iivalve ezinomgangatho omncinci zinokujikwa ngomnwe omnye, ngelixa ezinye iivalve zebhabhathane zasekhaya zinzima.Ukongeza kwi-coaxiality, i-symmetry, ukuchaneka kokucubungula, ukugqiba kunye nomgangatho wokupakisha, kakhulu Into ebalulekileyo yi-lubricity yezinto eziphathekayo.Umgangatho we-AWWA C504 uphakamisa ukuba umkhono we-shaft okanye i-bearing efakwe kumzimba we-valve kufuneka ibe yimpahla yokuzithambisa, kwaye umkhono we-shaft unengxaki yokunciphisa ukuxutywa kunye nokuthambisa, kwaye ukubola akuvumelekanga.Ngaphandle komkhono we-shaft, nokuba i-valve shaft yintsimbi engenasici, umzimba wevalve unomhlwa kunye neengxaki zokubambelela.Ukusetyenziswa kwe-bushings kunokunyusa ukuqina.
