Iivalvu yokujonga ipleyiti ezimbini ye-waferikwaluhlobo lwevalvu yokujonga ene-rotary actuation, kodwa yidiski ephindwe kabini kwaye ivalwa phantsi kwesenzo sesipringi. Idiski ityhalwa ivuleke lulwelo oluvela ezantsi ukuya phezulu, ivalvu inesakhiwo esilula, i-clamp ifakwe phakathi kweeflanges ezimbini, kwaye ubukhulu obuncinci kunye nobunzima obuphantsi buphantsi.
Iivalvu yokujonga ipleyiti ezimbini ye-waferineediski ezimbini ezifakwe kwintwasahlobo ezifakwe kwi-ribbed shaft ejikeleze i-valve bore. Olu lwakhiwo lunciphisa umgama ohamba phakathi kobunzima bediski. Olu lwakhiwo lukwanciphisa ubunzima bediski ngama-50% xa kuthelekiswa nevalvu yokujonga i-swing-on yediski enye enobukhulu obufanayo. Ngenxa yomthwalo wentwasahlobo, ivalvu isabela ngokukhawuleza kakhulu kwi-backflow.
Ulwakhiwo olulula lwevalvu yokuhlola iipleyiti ezimbini ye-wafer lwenza ukutywinwa kwesihlalo kunye nokusebenza kube lula ngakumbi.
Isenzo sentwasahlobo esinengalo ende sebhabhathane eliphindwe kabiniivalvu yokujongaivumela idiski ukuba ivuleke ize ivalwe ngaphandle kokukhuhla isihlalo, kwaye intwasahlobo isebenza ngokuzimeleyo ukuvala idiski (DN150 nangaphezulu).
Umkhono oxhasayo oneehinji webhabhathane elineziphelo ezimbiniivalvu yokujongaiyanciphisa ukungqubana kwaye inciphisa ihamile yamanzi xa ingasebenzi ngediski eyahlukileyo (imbobo enkulu).
Xa kuthelekiswa neqhelekileyoiivalvu zokujonga ukujika,ivalvu yokujonga ipleyiti ezimbini ye-waferUlwakhiwo ludla ngokuba lomelele, lukhaphukhaphu, luncinci, lusebenza ngakumbi, kwaye alubizi kakhulu. Le valve ihlangabezana nomgangatho we-API 594, kwiidayamitha ezininzi, ubungakanani bobuso ngobuso bale valve yi-1/4 kuphela yevalvu eqhelekileyo, kwaye ubunzima yi-15% ~ 20% yevalvu eqhelekileyo, ngoko ke ikwabiza kancinci kunevalvu yokujonga i-swing. Kulula kakhulu ukuyifaka phakathi kwee-gaskets eziqhelekileyo kunye nee-flanges zepayipi. Ngenxa yokuba kulula ukuyiphatha kwaye ifuna iseti enye yeebholiti zoqhagamshelo lweflange, ikwagcina izinto ngexesha lokufakela, igcina iindleko zokufakela kunye neendleko zokulungisa zemihla ngemihla.
Ivalvu yokujonga ibhabhathane eneziphene ezimbini ikwanazo neempawu zokwakha ezikhethekileyo ezenza le valve ibe yivalvu yokujonga engenampembelelo esebenza kakhulu. Ezi mpawu ziquka ukuvulwa okungenaziphene, ukwakhiwa kwentwasahlobo okuzimeleyo kwiivalvu ezininzi zebhore, kunye neenkqubo zokuxhasa iidiski ezizimeleyo. Ezinye zezi mpawu azifumaneki kwiivalvu zokujonga. Ivalvu yokujonga ipleyiti ezimbini ye-wafer inokuyilwa ngeelugs, iiflanges ezimbini kunye nomzimba owandisiweyo.
Okokuqala, inkqubo yokuvula nokuvala
Ulwakhiwo lweediski ezimbini luneediski ezimbini ezineentwasahlobo (iidiski ezimfutshane) ezixhonywe kwiphini eneehinged ethe nkqo embindini. Xa ulwelo luqala ukuhamba, idiski ivuleka ngamandla avelayo (F) asebenza embindini womphezulu wokuvala. Amandla okuxhasa intwasahlobo asebenzayo (FS) asetyenziswa kwindawo engaphandle embindini womphezulu wediski, nto leyo ebangela ukuba ingcambu yediski ivuleke kuqala. Oku kuthintela ukungqubana komphezulu wokuvala okwenzeka xa idiski ivulwa kwiivalvu ezindala zesiqhelo, kususa ukuguguleka kwezinto.
Xa isantya sokuhamba kwamanzi sincipha, i-torsion spring isabela ngokuzenzekelayo, nto leyo ebangela ukuba idiski ivale ize isondele kwisihlalo somzimba, nto leyo enciphisa umgama wokuhamba kunye nexesha lokuvala. Xa ulwelo lubuyela umva, idiski isondela kancinci kwisihlalo somzimba, kwaye impendulo eguquguqukayo yevalvu ikhawuleza kakhulu, nto leyo enciphisa isiphumo sehammer yamanzi kwaye ifezekise ukusebenza okungenampembelelo.
Xa kuvalwa, isenzo sendawo yokusebenza yamandla entwasahlobo sibangela ukuba umphezulu wediski uvaleke kuqala, nto leyo ethintela ukuluma nokungqubana kwingcambu yediski, ukuze ivalvu ikwazi ukugcina ingqibelelo yesitywina ixesha elide.
2. Isakhiwo sentwasahlobo esizimeleyo
Ulwakhiwo lwentwasahlobo (DN150 nangaphezulu) luvumela ukuba kusetyenziswe i-torque enkulu kwidiski nganye kwaye idiski ivala ngokuzimeleyo njengoko ukuhamba kwemizi-mveliso kutshintsha. Uvavanyo lubonise ukuba esi siphumo sibangele ukonyuka kwe-25% kubomi beevalvu kunye nokwehla kwe-50% kwihamile yamanzi.
Icandelo ngalinye lediski ephindwe kabini linezipringi zalo ezibonelela ngamandla okuvala azimeleyo kwaye ziphantsi kwe-angle offset encinci ye-140° (umzobo 3) endaweni ye-350° yepringi eqhelekileyo enezibiyeli ezimbini.
3. Ulwakhiwo oluzimeleyo lokumiswa kwediski
Ulwakhiwo lwehinge ezimeleyo lunciphisa ukungqubana ngama-66%, nto leyo ephucula kakhulu ukusebenza kwevalvu. Isleeve yokuxhasa ifakwe kwihinge engaphandle ukuze ihinge ephezulu ixhaswe ngokuzimeleyo yihinge esezantsi ngexesha lokusebenza kwevalvu. Oku kuvumela zombini iidiski ukuba zisabele ngokukhawuleza kwaye zivaleke ngaxeshanye, zifezekisa ukusebenza okugqwesileyo okuguquguqukayo.
Okwesine, imo yoqhagamshelo nombhobho
Iivalvu zokujonga iipleyiti ezimbini zeWaferkwaye imibhobho inokudityaniswa nee-clamps, ii-lugs, ii-flanges, kunye nee-clamps.
