Ivalve yebhabhathane ephakathi, ivalve yebhabhathane eneeccentric enye, ivalve yebhabhathane eccentric ephindwe kabini kunye nevalve yebhabhathane eccentric ephindwe kathathu, ezi ntlobo zeevalvu zebhabhathane zitshintsha indawo yokutywina kunye nokuvula ngokuseta indawo yepleyiti yevalve.
Ngaphantsi kweemeko ezifanayo, i-engile yokujikeleza efunekayo ukuze ipleyiti yevalve ikhutshwe kwisitywina xa ivalve ivuliwe incinci kunenye, kwaye ivalve iphantsi kwetorque enkulu kunomnye ekuvuleni ngakunye.
Ivalve yebhabhathane eccentric kathathu:
Ukumelana nokushisa okuphezulu, isitywina esinzima kufuneka sisetyenziswe, kodwa inani lokuvuza likhulu;Ukuvuza kwe-zero, itywina elithambileyo kufuneka lisetyenziswe, kodwa alikwazi ukumelana nobushushu obuphezulu.Ukoyisa ukuchasana kwevalve yebhabhathane ephindwe kabini, ivalve yebhabhathane ibiyeyona ndawo iphambili okwesithathu.Into ebizwa ngokuba yintliziyo yesithathu yimilo yesibini sokutywina asiyokhoni echanekileyo, kodwa ikhowuni ethambileyo.Isici esikhethekileyo se-valve ye-butterfly eccentric triple kukuba ivalve apho i-butterfly plate ifakwe khona i-shaft-shaft structure.Amacandelo amabini e-shaft ye-valve ye-valve yamacandelo amathathu agxininisekile, kwaye umgca ophakathi we-shaft yecandelo eliphakathi uhlanjululwe ukusuka kwiiphelo ezimbini ze-axis ngumgama ophakathi.Ipleyiti ifakwe kwicandelo le-shaft eliphakathi.Isakhiwo esinjalo se-eccentric senza ukuba i-disc ibe yi-double eccentric xa i-disc ivuleke ngokupheleleyo, kwaye ibe yi-eccentric enye xa i-disc ijikeleziswa kwindawo evaliweyo.Ngenxa yesenzo se-eccentric shaft, xa isondele ekuvaleni, ihambisa umgama kwindawo yokutywina ye-cone yesihlalo sevalve, kwaye ipleyiti yebhabhathane ihambelana nendawo yokutywina yesihlalo sevalve ukufezekisa ukutywinwa okuthembekileyo.
Ivalve yebhabhathane ene-eccentric ephindwe kabini:
Ngokusekwe kwivalve yebhabhathane ene-eccentric, yeyona isetyenziswa kakhulu ivelufa ephindwe kabini.Isici sayo sesakhiwo kukuba i-shaft center ye-valve stem iyaphambuka kumbindi we-disc kunye nombindi womzimba wevalve.Impembelelo ye-double eccentricity yenza ukuba i-disc ihlulwe ngokukhawuleza kwisihlalo se-valve emva kokuba i-valve ivuliwe, ephelisa kakhulu i-extrusion engafunekiyo kunye nokukrazula phakathi kwe-disc kunye nesihlalo se-valve, ukunciphisa ukuchasana kokuvula, ukunciphisa ukuguga, kunye nokuphucula i-valve. ubomi isihlalo ukusebenza.
Ivalve yebhabhathane enye eccentric:
Ukuze kulungiswe ingxaki ye-extrusion phakathi kwediski kunye nesihlalo sevalve yevalve yebhabhathane egxininisekileyo, iveliswa ivalve yebhabhathane eccentric.Iziko le-Axial, i-dispersion, ukunciphisa i-extrusion egqithisileyo yeendawo eziphezulu kunye nezisezantsi zeplate kunye nesihlalo sevalve.
Ivalve yebhabhathane yomgca osembindini
Isici sesakhiwo sevalve yebhabhathane yomgca ophakathi kukuba i-shaft center yesiqu, umbindi wediski kunye nombindi womzimba wevalve zikwindawo enye.Ngenxa yokuba ipleyiti yebhabhathane kunye nesihlalo sevalve zihlala zikwimo ye-extrusion kunye nokukhuhla, umgama wokumelana mkhulu kwaye ukunxiba kuyakhawuleza.Isakhiwo esilula nesifanelekileyo.Ukuze woyise i-extrusion kunye nokukrwela ukuqinisekisa ukusebenza kokutywinwa, isihlalo sevalve ngokusisiseko senziwe ngezinto ezilastiki ezifana nerabha okanye i-PTFE.
