E se e le lilemo tse fetang 50 esale ho hlahisoa valve ea serurubele sa eccentric triple, 'me esale e ntlafatsoa ka mokhoa o tsoelang pele lilemong tse 50 tse fetileng.Ho sebelisoa ha li-valve tsa serurubele ho atile liindasteri tse ngata.Belofo ea pele ea serurubele e sebelisoa feela bakeng sa ho kenella le ho hokahanya mecha ea litaba ea metsi.Moralo oa eccentric oa makhetlo a mararo o ntlafatsa ts'ebetso ea valve ea serurubele.E fetohile e 'ngoe ea li-valve tse nang le ts'ebetso e babatsehang tlas'a maemo a thata ka ho fetisisa tikolohong ea bohlokoa ea ts'ebetso ea lisebelisoa tsa lipeipi tsa indasteri.

Joalokaha lebitso le bontša, li-offsets tse tharo tse ikemetseng li entsoe e le li-valve.Triple eccentricity e bolela:

• Offset 1

Shaft e behiloe ka morao ho sefofane sa sebaka sa ho tiisa ho fana ka tsela e tsoelang pele ea setulo.

• Offset 2

Shaft e behoa ka lehlakoreng le leng la pipe / valve centerline ho felisa khohlano pakeng tsa tiiso le setulo

• Offset 3

Setulo le seal cone centerline li sekametse mabapi le pipe / valve centerline.Phetolelo ena ea boraro e felisa ho hohla ka ho feletseng.Khoune ena, hammoho le li-eccentric shaft offsets, li lumella disc hore e tiisetse setulong ntle le ho hohlana.

Moralo ona oa setulo o boetse o lumella ho tiisoa ha junifomo, 'me kahoo ho koaloa ka thata ka moralo oa setulo sa tšepe.Moralo ona ke theko e tlase, khetho e tlase ea torque (e bonolo ho e etsa), ho feta li-valve tsa tšepe tse lutseng.

Hangata li-offsets tse tharo li sebelisoa lits'ebetsong tsa ike high pressure steam (ho feta 150 PSI), mocheso o chesang haholo, likhase tse phahameng tsa mocheso le oli, lisebelisoa tsa mocheso o phahameng li loketse mofuta ona oa valve hobane ho hlokahala setulo sa tšepe holim'a setulo se bonolo.
