Iivalvu zeBhola
0102030405
B367 Gr.C-2 Worm Gear Operated Trunnion Mounted Ball Valve
Ulwakhiwo lweevalvu zebhola ezenziwe ngezinto ze-titanium alloy ikakhulu zibandakanya amacandelo afana nemizimba yevalvu, izigqubuthelo zevalvu, iziqu zevalvu, iingqukuva, kunye nezihlalo zevalvu. Olona phawu luphambili lweevalvu zebhola ye-titanium alloy yi-corrosion resistance, enokuthi isebenze ngokwesiqhelo kumajelo eendaba ezonakalisayo anjengeeasidi ezomeleleyo, iialkali ezomeleleyo, kunye neetyuwa. Ukongeza, ikwanezibonelelo ezinjengokumelana nobushushu obuphezulu, ukuxhathisa ukunxiba, kunye nobunzima obulula, kuyenza isetyenziswe ngokubanzi kumashishini afana nepetroleum, imichiza, isinyithi, kunye namandla. Umgaqo wayo wokusebenza kukusebenzisa i-valve stem ukuqhuba ukujikeleza kwebhola, ukwenza iziteshi ezahlukeneyo phakathi kwebhola kunye nesihlalo sevalve, ngaloo ndlela ufezekise ukuvulwa, ukuvala, kunye nokulungelelaniswa kwendawo. Xa i-sphere ijikeleza i-90 degrees, i-medium idlula kwi-valve; Xa i-sphere ijikeleza i-180 degrees, i-medium inqunywe ngokupheleleyo. Ukusebenza kwayo kokutywinwa kuxhomekeke kwindawo yoqhagamshelwano phakathi kwesphere kunye nesihlalo sevalve kunye nokusebenza kwesixhobo sokutywina.

Iimpawu ezongezelelweyo
1. Ibhola ixhaswa ziibheringi eziphezulu nezisezantsi, ukunciphisa ukungquzulana kunye nokuphelisa i-torque egqithisileyo eyenziwe ngumthwalo omkhulu wokutywina owenziwe luxinzelelo lokungena olutyhala ibhola kunye nesihlalo sokutywina.
2. Iringi yokutywina ye-PTFE enye ifakwe kwisihlalo sevalve yensimbi engenasici, kwaye i-spring ifakwe ekupheleni kwesihlalo sevalve yesinyithi ukuqinisekisa ukuba umsesane wokutywina unamandla okwaneleyo okuqinisa kwangaphambili. Nokuba indawo yokutywina iyaphela ngexesha lokusetyenziswa, isenokuqinisekisa ukusebenza kakuhle kokutywinwa phantsi kwesenzo sentwasahlobo.
3. Ukuze kuthintelwe ukwenzeka komlilo, ikhonkco lokutywina lomlilo lifakwe phakathi kwe-sphere kunye nesihlalo sevalve. Xa umsesane wokutywina utshisiwe, phantsi kwesenzo samandla entwasahlobo, ikhonkco lokutywina isihlalo sevalve sityhalelwa ngokukhawuleza kwi-sphere, lenze isinyithi ukuya kwitywina lesinyithi, ifezekisa isiphumo sokutywinwa okuthile. Uvavanyo lokumelana nomlilo luhlangabezana neemfuno zemigangatho ye-APl6FA kunye ne-APl607.
4. Xa uxinzelelo lwendawo evalelekileyo kwigumbi levalvu lunyuka ngokungaqhelekanga ngaphaya koxinzelelo lwangaphambili lwentwasahlobo, isitulo sevalvu siya kurhoxa kwaye siqhawule kwisphere, siphumeze isiphumo sokukhululeka koxinzelelo oluzenzekelayo. Emva kokunciphisa uxinzelelo, isihlalo sevalve siya kubuya ngokuzenzekelayo
5. Imingxuma yokukhupha amanzi ifakwe kumacala omabini omzimba wevalvu ukujonga ukuvuza kwesitulo sevalvu. Ngethuba lokusebenza, xa i-valve ivuliwe ngokupheleleyo okanye ivalwe ngokupheleleyo, uxinzelelo olukwigumbi eliphakathi lunokususwa kwaye ukupakisha kunokutshintshwa ngokuthe ngqo; Iyakwazi ukukhupha izinto ezishiyekileyo kwigumbi eliphakathi kwaye inciphise ukungcoliseka kwendawo ephakathi kwivalve.
6.Ngenxa yezinto zangaphandle kwi-medium okanye umlilo obangela ukusilela ngengozi kwesitywina sesihlalo sevalve, ivalve yegrisi ibonelela ngonxibelelwano olukhawulezayo kunye nompu wegrisi, kunye nempompo ethunyelwa ngaphandle ngokufanelekileyo kwaye ngokukhawuleza ifake igrisi yokutywina kwindawo yokutywina isihlalo sevalve ukunciphisa ukuvuza.
7. Ukongeza kokumisela amakhonkco okutywinwa okusemgangathweni, izitywina ze-O-ring nazo zifakwe kwi-packing gland, ziqinisekisa ukuthembeka kwe-valve stem seal kunye nokutywinwa kabini; Ukongezwa kokupakishwa kwegraphite kunye nokutywinwa kwesitofu segrisi kunciphisa ukuvuza kwesikhondo sevalve emva komlilo. Iibheringi ezityibilikayo kunye neebheringi zokutyhala zesikhondo sevalve zenza ukusebenza kwevalve kube lula.
8. Izakhiwo zokubhoboza ngokupheleleyo okanye ezincitshisiweyo zinokukhethwa njengoko zifuneka. Umbhobho wokuhamba wevalve egcweleyo uyahambelana nedayamitha yangaphakathi yombhobho, nto leyo eyenza kube lula ukucoca umbhobho.
9. Ngokweemfuno zofakelo okanye zokusebenza, i-valve stem inokwandiswa. Ivalve yebhola yentonga eyandisiweyo, ilungele ngakumbi irhasi yasezidolophini kunye nezinye iziganeko ezifuna ukubekwa kwemibhobho engcwatyiweyo. Ubungakanani besikhondo sevalve eyandisiweyo buya kumiselwa ngokweemfuno zomthengi.
10. Ukusetyenziswa kwesihlalo kunye ne-stem bearings kunye ne-coefficient encinci ye-friction kunye ne-self-lubricating properties inciphisa kakhulu i-torque yokusebenza yevalve. Ngoko ke, nangaphandle kokubonelela ngegrisi yokutywina, i-valve inokusebenza ngokuguquguqukayo kwaye ngokukhululekileyo ixesha elide.
