Ivalve yebhabhathane etywiniweyo eqinile
Ukutywinwa okunzima kwevalve yebhabhathane kubhekiselele ekubeni omabini amacala esibini sokutywina enziwe ngezinto zentsimbi okanye ezinye izinto eziqinileyo.Ukutywinwa kolu hlobo lwesitywina kubi, kodwa kunokumelana nobushushu obuphezulu, ukumelana nokunxiba kunye nokusebenza kakuhle koomatshini.Umzekelo: intsimbi + yentsimbi;Intsimbi+ubhedu;Intsimbi+graphite;Intsimbi + yentsimbi yealloyi.Intsimbi apha isenokuba yintsimbi etyhidiweyo, intsimbi ekhandiweyo, intsimbi exutywe nengxubevange okanye ialloyi yokujonga phezulu nokutshiza.
Ivalve yebhabhathane ethambileyo
Isitywina esithambileyo sevalve yebhabhathaneibhekisa kwicala elinye lesibini sokutywina lenziwe ngezinto zentsimbi, kwaye elinye icala lenziwe ngelastiki engeyiyo isinyithi.Ukusebenza kokutywinwa kolu hlobo lwesitywina kulungile, kodwa akuxhathisi ukushisa okuphezulu, kulula ukunxiba, kwaye kunokusebenza kakubi komatshini, njengale: intsimbi + irabha;Intsimbi+PTFE, njl.
Isihlalo sotywino esithambileyo senziwe ngezinto ezingezona zetsimbi ezinamandla athile, ukuqina kunye nokumelana nobushushu.Ngokusebenza kakuhle, inokufikelela kwi-zero ukuvuza, kodwa ubomi bayo benkonzo kunye nokulungelelaniswa kobushushu bunzima.Isitywina esiqinileyo senziwe ngentsimbi, kwaye ukusebenza kokutywina kumbi kakhulu.Nangona abanye abavelisi bebanga ukuba ukuvuza kwe-zero kunokufezekiswa.Itywina elithambileyo alikwazi ukuhlangabezana neemfuno zenkqubo kwezinye izinto ezidlekayo.Ukutywinwa okuqinileyo kunokusombulula ingxaki, kwaye la matywina mabini anokuncedisana.Ngokubhekiselele ekusebenzeni kokutywinwa, ukutywinwa okuthambileyo kulungile, kodwa ngoku ukutywinwa kokutywinwa okuqinileyo nako kunokwanelisa iimfuno ezihambelanayo.Iingenelo zetywina elithambileyo kukusebenza kakuhle kokutywinwa, ngelixa izinto ezingeloncedo kukuguga lula, ukunxiba kunye nobomi obufutshane benkonzo.Itywina elinzima linobomi benkonzo obude, kodwa ukusebenza kwayo kokutywinwa kubi kakhulu kunoko kutywinwa okuthambileyo.
Umahluko kulwakhiwo ikakhulu ngolu hlobo lulandelayo:
1. Ukwahluka kwesakhiwo
Iivalvu zebhabhathane ezithambileyoubukhulu becala zezodidi oluphakathi, lo gama iivalvu zebhabhathane etywiniweyo ubukhulu becala ziyi-eccentric enye, i-double eccentric kunye ne-triple eccentric type.
2. Ukumelana nobushushu
Isitywina esithambileyo sisetyenziswa kwindawo yobushushu obuqhelekileyo.Ukutywinwa okuqinileyo kungasetyenziselwa ubushushu obuphantsi, ubushushu obuqhelekileyo, ubushushu obuphezulu kunye nezinye iindawo.
3. Uxinzelelo
Uxinzelelo oluthambileyo lwetywina oluphantsi - uxinzelelo oluqhelekileyo, isitywina esiqinileyo sinokusetyenziswa kwiimeko zokusebenza ezifana noxinzelelo oluphakathi kunye nophezulu.
4. Ukusebenza kokutywinwa
Ukusebenza kokutywina kwevalve yebhabhathane etywiniweyo kunye nevalve yebhabhathane eqinileyo etywinayo ingcono.Ivalve yebhabhathane ye-tri eccentric inokugcina ukutywinwa okulungileyo phantsi koxinzelelo oluphezulu kunye nokusingqongileyo kobushushu obuphezulu.
Ngenxa yezi mpawu zingasentla, iivalve yebhabhathane yokutywina ethambileyoilungele ukuvulwa kunye nokuvala iindlela ezimbini kunye nohlengahlengiso lwemibhobho yokuphuma komoya kunye nokususa uthuli, unyango lwamanzi, imboni yokukhanya, i-petroleum, imboni yeekhemikhali kunye namanye amashishini.Ivalve yebhabhathane etywiniweyo isetyenziswa ikakhulu ukufudumeza, unikezelo lwerhasi, irhasi, ioyile, iasidi kunye nokusingqongileyo kwealkali.
Ngokusetyenziswa ngokubanzi kwevalve yebhabhathane, iimpawu zayo zofakelo olufanelekileyo, ukugcinwa okufanelekileyo kunye nesakhiwo esilula sibonakala ngakumbi nangakumbi.Iivalvu zebhabhathane ezithambileyo zombane, iivalve zebhabhathane ezithambileyo zomoya, iivalve zebhabhathane eziqinileyo, njl.njl. ziqala ukutshintsha iivalvu zesango zombane, iivalvu zeglowubhu, njl. njl.
