Iivalve yeplastiki yebhabhathaneidityaniswe nenkqubo yemibhobho ngezi ndlela zilandelayo:

Uxhulumaniso lwe-Butt welding: I-diameter yangaphandle yecandelo lokudibanisa ivalve ilingana nobubanzi obungaphandle bombhobho, kwaye isiphelo sobuso bendawo yokudibanisa ivalve ichasene nobuso besiphelo sombhobho wokudibanisa;

Uxhulumaniso lwe-socket bonding: inxalenye yokudibanisa i-valve ikwimo yesokhethi, edibeneyo kumbhobho;

Uqhagamshelo lwesokhethi ye-Electrofusion: inxalenye yokudibanisa i-valve luhlobo lwesokethi kunye nocingo lokufudumeza lombane olubekwe kwi-diameter yangaphakathi, kwaye ludibaniso lwe-electrofusion kunye nombhobho;

I-Socket hot-melt uxhumano: inxalenye yokudibanisa i-valve ikwimo yesokhethi, kwaye idibaniswe nombhobho nge-socket-melt socket;

Uxhulumaniso lwe-socket bonding: Inxalenye yokudibanisa i-valve ikwimo yesokhethi, edibeneyo kwaye ifakwe ngombhobho;

Ikhonkco lokutywinwa kwe-rubber ye-socket: Inxalenye yokudibanisa i-valve luhlobo lwe-socket kunye nendandatho yokutywinwa kwe-rubber ngaphakathi, egxininiswe kwaye idibene nombhobho;

Uxhumo lwe-Flange: Inxalenye yokudibanisa i-valve ikwimo ye-flange, edibaniswa ne-flange kumbhobho;

Uxhulumaniso lwentambo: Inxalenye yokudibanisa ivalve ikwimo yentambo, edityaniswe nentambo kumbhobho okanye ukufakwa kombhobho;

Uqhagamshelo oluphilayo: Inxalenye yoqhagamshelo lwevalvu lunxibelelwano oluphilayo, oludityaniswe naloimibhobho okanye izifakelo.

Ivalve ingaba neendlela ezahlukeneyo zokudibanisa ngexesha elinye.

umgaqo wokusebenza:

Ubudlelwane phakathi kokuvulwa kwevalve yebhabhathane yeplastiki kunye nesantya sokuhamba ngokusisiseko sitshintsha ngokulandelelana.Ukuba isetyenziselwa ukulawula ukuhamba, iimpawu zayo zokuhamba nazo zihambelana ngokusondeleyo nokumelana nokuhamba kombhobho.Ngokomzekelo, imibhobho emibini ifakwe kunye nobubanzi obufanayo bevalve kunye nefom, kodwa i-coefficient yokulahlekelwa kombhobho yahlukile, kwaye izinga lokuhamba kwevalve liya kwahluka kakhulu.

Ukuba i-valve ikwimeko enoluhlu olukhulu lwe-throttle, umva weplate ye-valve ixhomekeke kwi-cavitation, enokonakalisa i-valve.Ngokuqhelekileyo, isetyenziswe ngaphandle kwe-15 °.

Xa ivalve yebhabhathane yeplastiki ikwindawo ephakathi yokuvula, imilo yembobo eyenziwe ngumzimba wevalve kunye nencam yangaphambili yepleyiti yebhabhathane ibekwe embindini wevalufa yevalve, kwaye amacala omabini abunjwa ukuze agqibezele amazwe ahlukeneyo.Incam engaphambili yepleyiti yebhabhathane kwelinye icala iya kwicala lokuhamba kwamanzi, lize elinye icala lichasene necala lokuqukuqela kwawo.Ke ngoko, elinye icala lomzimba wevalve kunye nepleyiti yevalve yenza ukuvulwa okufana nombhobho, kwaye elinye icala lifana nokuvula i-throttle.Icala le-nozzle linesantya sokuhamba ngokukhawuleza kunecala le-throttle, kwaye uxinzelelo olubi luya kuveliswa phantsi kwevalve yecala le-throttle.Amatywina erabha ahlala ewa.

Iivalvu zebhabhathane zeplastiki kunye neentonga zebhabhathane azinasakhono sokuzivalela.Ukubeka ipleyiti yebhabhathane, isinciphisi segiya leentshulube kufuneka sifakwe kwintonga yevalve.Ukusetyenziswa kwe-worm gear reducer ayikwazi nje ukwenza i-butterfly plate self-locking kwaye imise ipleyiti yebhabhathane kuyo nayiphi na indawo, kodwa iphucula ukusebenza kwevalve.

I-torque esebenzayo yevalve yebhabhathane yeplastiki inexabiso elahlukileyo ngenxa yokuvula nokuvala okwahlukeneyo kwevalve.Ivalve yebhabhathane ethe tyaba, ngakumbi i-valve-diameter enkulu, ngenxa yobunzulu bamanzi, i-torque eveliswa ngumahluko phakathi kweentloko zamanzi eziphezulu kunye nezisezantsi ze-valve shaft ayikwazi ukuhoywa.Ukongezelela, xa i-elbow ifakwe kwicala lokungena kwi-valve, ukuhamba kwe-bias kwenziwa, kwaye i-torque iya kwanda.Xa i-valve iphakathi kokuvula, indlela yokusebenza kufuneka izivalele ngenxa yesenzo se-torque yamanzi.

I-valve ye-butterfly yeplastiki inesakhiwo esilula, esiquka iindawo ezimbalwa kuphela, kwaye igcina ukusetyenziswa kwezinto eziphathekayo;ubungakanani obuncinci, ubunzima obuncinane, ubungakanani obuncinci bokufaka, i-torque encinci yokuqhuba, ukusebenza okulula kunye nokukhawuleza, kufuneka kuphela ukujikeleza i-90 ° ngokukhawuleza ukuvula nokuvala;kwaye Ngexesha elifanayo, linomsebenzi wokulungelelanisa ukuhamba kakuhle kunye neempawu zokuvala kunye nokutywinwa.Kwintsimi yesicelo somgangatho omkhulu kunye nophakathi, uxinzelelo oluphakathi kunye oluphantsi, ivalve yebhabhathane yeyona ndlela iphambili yevalve.Xa ivalve yebhabhathane ikwindawo evuleleke ngokupheleleyo, ubukhulu bepleyiti yebhabhathane yeyona nto ixhathisayo xa i-medium iqukuqela kumzimba wevalve, ngoko ke ukuhla koxinzelelo okwenziwa yivalve kuncinci, ngoko ke ineempawu zokulawula ukuhamba kakuhle.Ivalve yebhabhathane ineentlobo ezimbini zokutywina: isitywina esilastiki kunye nesitywina sentsimbi.Ivalve yokutywina ethambileyo, umsesane wokutywina unokufakwa kumzimba wevalvu okanye uncanyathiselwe kumda wepleyiti yebhabhathane.Iivalvu ezinamatywina entsimbi zinobomi obude kuneevalvu ezinamatywina, kodwa kunzima ukufezekisa itywina elipheleleyo.Isitywina sentsimbi sinokuqhelana nobushushu obuphezulu bokusebenza, ngelixa itywina elilastiki linesiphene sokunqandwa bubushushu.Ukuba i-valve butterfly iyadingeka ukuba isetyenziswe njengolawulo lokuhamba, into ephambili kukuba ukhethe ngokuchanekileyo ubungakanani kunye nohlobo lwevalve.Umgaqo-siseko wevalve yebhabhathane ifanelekile ngokukodwa ukwenza iivalve ezinobubanzi obukhulu.Iivalvu zebhabhathane azisetyenziswa ngokubanzi kuphela kumashishini ngokubanzi afana nepetroleum, igesi, imichiza, kunye nonyango lwamanzi, kodwa zikwasetyenziswa kwiinkqubo zokupholisa zamanzi kwizikhululo zamandla obushushu.Iivalvu zebhabhathane ezisetyenziswa ngokuqhelekileyo ziquka iivalve zebhabhathane zohlobo lwe-wafer kunye ne-flange type butterfly valves.Iivalve zebhabhathane zeWafer ziqhagamshelwe phakathi kweeflange zemibhobho emibini eneebholiti.Iivalve zebhabhathane ezinamaphiko zixhotyiswe ngeeflange kwivalve.Iiflange kwiiphelo zombini zevalve zixhunywe kwiiflange zepayipi ngeebholiti.Ukusebenza kokuqina kwevalve kubhekiselele ekukwazini kwevalve ukumelana noxinzelelo lwesixhobo esiphakathi.I-valve yimveliso yomatshini ethwele uxinzelelo lwangaphakathi, ngoko kufuneka ibe namandla okwaneleyo kunye nokuqina ukuze kuqinisekiswe ukusetyenziswa kwexesha elide ngaphandle kokuqhekeka okanye ukuguqulwa.

Ngokusetyenziswa kwerubha yokwenziwa kwe-anti-corrosion kunye ne-polytetrafluoroethylene, ukusebenza kweevalve zebhabhathane kunokuphuculwa kwaye kuhlangabezane neemeko ezahlukeneyo zokusebenza.Kule minyaka ilishumi idluleyo, izivalo zebhabhathane ezitywina intsimbi ziye zavela ngokukhawuleza.Ngokusetyenziswa kokumelana nobushushu obuphezulu, ukuxhathisa ubushushu obuphantsi, ukuxhathisa okuqinileyo komhlwa, ukuxhathisa okuqinileyo kokhukuliseko, kunye nemathiriyeli ephezulu yealloy kwiivalvu zebhabhathane, iivalvu zebhabhathane zokutywina zisetyenzisiwe kubushushu obuphezulu, ubushushu obuphantsi, kunye nokhukuliseko olunamandla.Isetyenziswe ngokubanzi phantsi kwezinye iimeko zokusebenza kwaye ithathe indawo yevalve yehlabathi,ivalve yesangokunye nevalve yebhola.
