IIvalve yokujonga ipleyiti ephindwe kabiniluhlobo lwevalve yokukhangela ene-rotary actuation, kodwa idiski ephindwe kabini kwaye ivale phantsi kwesenzo sentwasahlobo. I-disc ityhilwa ivuleke nge-low-up fluid, i-valve inesakhiwo esilula, i-clamp ifakwe phakathi kwee-flanges ezimbini, kwaye ubungakanani obuncinci kunye nobunzima bokukhanya buphantsi.
IIvalve yokujonga ipleyiti ephindwe kabiniineecwecwe ezimbini ezimilise okwe-D ezibekwe kwi-ribbed shaft ngapha kwebhore yevalve. Esi sakhiwo sinciphisa umgama wokuba umbindi womxhuzulane wediski uhamba. Olu lwakhiwo lunciphisa ubunzima be-disc nge-50% xa kuthelekiswa ne-disc-swing-on check valve yobukhulu obufanayo. Ngombulelo kumthwalo wentwasahlobo, i-valve isabela ngokukhawuleza kakhulu kwi-backflow.
Ulwakhiwo lwevalvu ephindwe kabini yepleyiti yokujonga i-lobe-lobe lightweight yenza ukutywinwa kwesitulo kunye nokusebenza kakuhle ngakumbi.
Isenzo sentwasahlobo yengalo emide yebhabhathane eliphindwe kabinikhangela ivalveivumela i-disc ukuba ivule kwaye ivale ngaphandle kokuxubha isihlalo, kwaye intwasahlobo isebenza ngokuzimeleyo ukuvala i-disc (i-DN150 nangaphezulu).
Umkhono wenkxaso ohinjisiweyo webhabhathane eline-flap ephindwe kabinikhangela ivalvekunciphisa ukukhuhlana kunye nokunciphisa ihamile yamanzi xa ikhutshwe ngediski eyahlukileyo (ibhongo elikhulu).
Xa kuthelekiswa nesiqheloswing check valves,Ivalve yokujonga ipleyiti ephindwe kabiniulwakhiwo lukholisa ukuba namandla, khaphukhaphu, luncinci, lusebenza kakhulu, kwaye lungabizi kakhulu. Le valve idibana nomgangatho we-API 594, kuninzi lweediameters, ubukhulu bobuso ngobuso beli valve yi-1/4 kuphela yevalve yesiqhelo, kwaye ubunzima buyi-15% ~ 20% yevalve yesiqhelo, ngoko kunjalo. kwakhona zitshiphu kunevalve yokujonga ujingi. Kwakhona kulula ukuyifaka phakathi kwee-gaskets eziqhelekileyo kunye neeflange zepayipi. Ngenxa yokuba kulula ukuyiphatha kwaye ifuna enye kuphela isethi yokudibanisa i-flange, iphinda igcine amacandelo ngexesha lofakelo, ukugcina iindleko zofakelo kunye neendleko zokugcinwa kwemihla ngemihla.
Ivalve yokujonga ibhabhathane ephindwe kabini nayo ineempawu ezikhethekileyo zokwakha ezenza le valve ibe yivalve yokukhangela engasebenziyo. Ezi mpawu ziquka ukuvulwa okungacocekiyo, ukwakhiwa kwentwasahlobo ezimeleyo kwiivalvu ezininzi, kunye neenkqubo ezizimeleyo zenkxaso yediski. Ezinye zezi mpawu azifumaneki ngeevalvu zokutshekisha. Ivalve yokujonga ipleyiti ephindwe kabini inokuthi iyilwe ngeelugs, iiflange ezimbini kunye nomzimba owandisiweyo.
Okokuqala, inkqubo yokuvula kunye nokuvala
Ulwakhiwo lwe-disc oluphindwe kabini lune-disc ezimbini ezilayishwe entwasahlobo (i-semi-discs) zinqunyanyiswe kwisikhonkwane esinehenjisi esithe nkqo embindini. Xa i-fluid iqala ukuhamba, i-disc ivula ngamandla anesiphumo (F) esebenza embindini wokutywinwa komhlaba. I-counteractive spring support force (FS) isetyenziswe kwindawo engaphandle kwendawo yobuso bediski, ibangela ukuba i-disc root ivule kuqala. Oku kunqanda ukungqubuzana kwindawo yokutywinwa okwenzekayo xa i-disc ivulwa kwiivalvu ezindala eziqhelekileyo, ukuphelisa ukuguga kunye nokukrazula kumacandelo.
Xa izinga lokuhamba linciphisa, intwasahlobo ye-torsion isabela ngokuzenzekelayo, ibangela ukuba i-disc ivale kwaye isondele kufuphi nesihlalo somzimba, ukunciphisa umgama wokuhamba kunye nexesha lokuvala. Xa i-fluid ibuyela ngasemva, i-disc isondela ngokuthe ngcembe kwisihlalo somzimba, kwaye impendulo eguquguqukayo ye-valve ikhawuleza kakhulu, inciphisa umphumo wesando samanzi kunye nokufezekisa ukusebenza okungenayo impembelelo.
Xa uvala, isenzo se-spring force point point sibangela ukuba i-disc ivalwe kuqala, ithintele ukubetha kunye ne-friction kwingcambu yediski, ukwenzela ukuba i-valve ikwazi ukugcina ingqibelelo yesitywina ixesha elide.
2. Isakhiwo esizimeleyo sentwasahlobo
Ukwakhiwa kwentwasahlobo (i-DN150 nangaphezulu) ivumela ukuba i-torque enkulu isetyenziswe kwi-disc nganye kwaye i-disc ivala ngokuzimeleyo njengoko utshintsho lwezoshishino lutshintsha. Iimvavanyo zibonise ukuba esi siphumo sibangele ukunyuka kwe-25% kubomi bevalvu kunye nokunciphisa i-50% kwihamile yamanzi.
Icandelo ngalinye le-disc ephindwe kabini linemithombo yalo enika amandla okuvala ngokuzimeleyo kwaye ixhomekeke kwi-offset encinci ye-angular ye-140 ° (umzobo 3) endaweni ye-350 ° yentwasahlobo eqhelekileyo enezibiyeli ezimbini.
3. Isakhiwo sokumiswa kwediski esizimeleyo
Isakhiwo sehinge esizimeleyo sinciphisa ukukhuhlana nge-66%, ephucula kakhulu i-reactivity ye-valve. I-sleeve yenkxaso ifakwe kwi-hinge yangaphandle ukwenzela ukuba i-hinge ephezulu inokuxhaswa ngokuzimeleyo ngumkhono ophantsi ngexesha lokusebenza kwe-valve. Oku kuvumela zombini iidiski ukuba zisabele ngokukhawuleza kwaye zivale ngaxeshanye, zifezekise ukusebenza okubalaseleyo.
Okwesine, indlela yokudibanisa kunye nombhobho
Iivalvu zokujonga iipleyiti ezimbinikunye nemibhobho inokudityaniswa ne-clamp, i-lugs, i-flanges kunye ne-clamp.
