Ivalvu yebhabhathane esembindini inesakhiwo esilula nesilula ukuyenza, kodwa ngenxa yesakhiwo sayo kunye nemida yezinto ezisetyenzisiweyo, iimeko zokusetyenziswa zilinganiselwe. Ukuze kuhlangatyezwane neemfuno zeemeko zokusetyenziswa, kwenziwe uphuculo oluqhubekayo ngale ndlela, kwaye emva koko kwavela iivalvu zebhabhathane ezingaqhelekanga, iivalvu zebhabhathane ezingaqhelekanga ezimbini, kunye neevalvu zebhabhathane ezingaqhelekanga ezintathu. Uphawu olukhulu lolu hlobo lwesithathu kukuba lutshintsha ngokusisiseko isakhiwo sokutywina. Ayiseyiyo itywina yendawo, kodwa yitywina yokutsalwa, oko kukuthi, ayixhomekekanga kwi-elastic deformation yesihlalo sevalvu, kodwa ixhomekeke ngokupheleleyo kuxinzelelo lomphezulu woqhagamshelwano lwesihlalo sevalvu. Isiphumo sokutywina, ke ngoko, sisombulula ingxaki yokungavuzi kwesihlalo sevalvu yesinyithi kwi-swoop enye ewileyo, kwaye ngenxa yokuba uxinzelelo lomphezulu woqhagamshelwano luhambelana noxinzelelo oluphakathi, uxinzelelo oluphezulu kunye nokumelana nobushushu obuphezulu nako kusonjululwa ngokulula.

Iingenelo zoyilo oluphindwe kathathu

1. Uyilo olulodwa lwe-conical seal luqinisekisa ukuba idiski ayichukumisi umphezulu wokuvala ide ivalwe ivalvu- oku kukhokelela kwi-seal ephindaphindwayo kwaye kwandisa kakhulu ubomi be-valvu.

2. Imilo yepleyiti yevalvu yevalvu yebhabhathane engaqhelekanga kathathu yikhowuni eli-elliptical, kwaye umphezulu wayo udityaniswe nge-alloy eqinileyo, enokumelana okuhle nokuguguleka. Isihlalo sentsimbi engenasici esintantayo esinomfanekiso we-U sinomsebenzi wokulungisa ngokuzenzekelayo iziko. Xa ivalvu ivuliwe, idiski yevalvu yokutywina yekhowuni e-elliptical iqala yahlulwe kwisihlalo sevalvu ye-elastic enesimo se-U, ize ijikeleze; xa ivaliwe, idiski yevalvu iyajikeleza, kwaye idiski yevalvu ilungisa ngokuzenzekelayo iziko kwisihlalo sevalvu ye-elastic phantsi kwesenzo seshaft engaqhelekanga. Isihlalo sifaka uxinzelelo lokuguqula isihlalo sevalvu de isihlalo sevalvu kunye nomphezulu wokutywina wekhowuni e-elliptical wediski yevalvu zihambelane ngokusondeleyo. Xa ivalvu ivuliwe kwaye ivaliwe, idiski yebhabhathane ayikrweli isihlalo sevalvu, kwaye i-torque yesiqu sevalvu idluliselwa ngqo kumphezulu wokutywina ngeplate yebhabhathane, kwaye i-torque yokuvula incinci, ngaloo ndlela isusa into eqhelekileyo yokutsiba xa uvula ivalvu.

3. Ukutywinwa kwesinyithi kuqinisekisa ukuba amaqamza omoya avaliwe kakuhle ukuze kungabikho kuvuza

4. Ifanelekile kwiindawo eziqinileyo-isakhiwo esenziwe ngesinyithi sonke sibonelela ngomhlwa kunye nokumelana nobushushu okungenazo ezinye iivalvu zebhabhathane ezinezitywina ze-elastiki

5. Uyilo lwejometri lwezinto zokutywina lunokubonelela ngokuhamba ngaphandle kokungqubana kuyo yonke ivalvu. Oku kwandisa ubomi bevalvu kwaye kuvumela ukufakwa kwee-actuators ze-torque ezisezantsi.

6. Akukho mngxuma phakathi kwezinto zokuvala, ongenakubangela ukuvaleka, ukunciphisa iindleko zokugcina nokwandisa ubomi bevalvu.

7. Uyilo lwesihlalo sevalvu lunokuthintela ivalvu ukuba ingatyibiliki kakhulu
