Kwintsimi yeevalvu zoshishino, iivalve zebhabhathane zisetyenziswa kakhulu kumashishini ahlukeneyo afana neoyile negesi, unyango lwamanzi, ukusetyenzwa kweekhemikhali, njl.njl. Phakathi kweentlobo ezahlukeneyo zevalve yebhabhathane, iivalve ezimbini zikhokele: ivalve yebhabhathane ephindwe kabini kunye ne-triple eccentric. ivelufa butterfly.Kolu thelekiso lubanzi, siya kujonga nzulu kuyilo, iingenelo, izinto ezingeloncedo kunye nokusetyenziswa kwezi valves zimbini.
Ivalve yebhabhathane ephindwe kabini
Njengoko igama libonisa, iivalvu zebhabhathane eziphindwe kabini zineendlela ezimbini zokulinganisa: eyokuqala yi-shaft eccentricity, oko kukuthi, ukushenxiswa kwe-axis ye-shaft ukusuka kumgca osembindini wombhobho, kwaye eyesibini i-offset yi-eccentricity yetywina, oko kukuthi, ijometri yesitywina sediski yevalve.Olu luyilo lunenzuzo ebalulekileyo kunye nokungalunganga.
Izinto eziluncedo zevalve yebhabhathane eccentric ephindwe kabini
1. Ukunxiba okucuthiweyo
Injongo yoyilo lwe-shaft eccentricity kukunciphisa ukukhuhlana phakathi kwepleyiti yevalve kunye nesitulo sevalvu ngexesha lokuvula kunye nenkqubo yokuvala, ngaloo ndlela ukunciphisa ukuguga kunye nokunciphisa umngcipheko wokuvuza.Inokwandisa ubomi bevalve yebhabhathane kunye nokunciphisa iindleko zokugcinwa.
2. Ukutywinwa okuphuculweyo
I-eccentricity yesibini yenza indawo yokutywina idibanise isihlalo se-valve kuphela kwinqanaba lokugqibela lokuvala, elingaqinisekisi nje isitywina esiqinileyo, kodwa lilawula ngokufanelekileyo i-medium.
3. Itorque encitshisiweyo
Uyilo oluphindwe kabini lwe-offset lunciphisa i-coefficient ye-friction, enciphisa amandla afunekayo ukuvula nokuvala ivalve yebhabhathane.
4. Ukutywinwa kwamacala amabini
Iivalvu zebhabhathane ezineeccentric eziphindwe kabini zinokutywina ngokuphindwe kabini, zivumela ukuhamba kwe-bidirectional, kwaye kulula ukuyifaka kunye nokusetyenziswa.
Ukungalungi kweevalvu zebhabhathane eccentric kabini:
1. Iindleko eziphezulu
Uyilo oluphucukileyo kunye nemathiriyeli yeevalvu zebhabhathane eccentric eccentric ngokubanzi zikhokelela kwiindleko eziphezulu zokwenziwa xa kuthelekiswa neevalvu zebhabhathane ezisembindini.
2. Uxinzelelo oluninzi lwamanzi lulahlekelwa
Ngenxa yokuqina kwepleyiti yevalvu ephindwe kabini, isitulo sevalve ephumayo, kunye neendlela ezimxinwa, uxinzelelo lwamanzi oluphulukana nevalve yebhabhathane lunokwenyuka.
3. Uluhlu lobushushu obulinganiselweyo
Iivalvu zebhabhathane eccentric kabini zinokuthintelwa xa uphethe ubushushu obuphantsi kakhulu okanye imidiya ephezulu yobushushu kuba izixhobo ezisetyenzisiweyo zisenokungamelani namaqondo obushushu agqithisileyo.
Ivalve yebhabhathane ye-Offset kathathu
Ivalve yebhabhathane ephindwe kathathu imele uphuhliso olongezelelekileyo loyilo lwevalvu yebhabhathane eneendlela ezintathu.Kwisiseko se-double eccentric, i-eccentricity yesithathu yi-offset ye-axis xa kuthelekiswa nombindi womzimba wevalve.Olu lwakhiwo luyinzuzo ekhethekileyo ngaphezu kwevalve yebhabhathane yesiqhelo.
Izinto eziluncedo kwi-triple eccentric butterfly valves
1. Ukuvuza kweZero
Ubume obukhethekileyo bento yokutywina yevalve yebhabhathane ene-eccentric eccentric isusa ukukhuhlana kunye nokunxiba, okukhokelela ekutywineni okuqinileyo kubo bonke ubomi bevalve.
2. Ukushisa okuphezulu kunye nokuchasana noxinzelelo oluphezulu
Zombini ivalve yebhabhathane enentsimbi ephindwe kathathu eccentric kunye nevalve yebhabhathane enamaleko amaninzi amathathu inokumelana nobushushu obuphezulu kunye noxinzelelo oluphezulu lolwelo.
3. Uyilo olungatshiyo
Zonke izixhobo zevalve yebhabhathane ye-eccentric eccentric inokuhlangabezana nemigangatho engqongqo yokumelana nomlilo, iyenze ibalasele kwizicelo ezingatshiyo.
4. I-torque ephantsi kunye ne-friction
Ivalve yebhabhathane ye-eccentric eccentric inokunciphisa ngakumbi ukusebenza kwe-torque kunye ne-friction, ngaloo ndlela ifezekisa ukusebenza kakuhle, ukunciphisa i-torque kunye nokwandisa ubomi benkonzo.
5. Uluhlu olubanzi lwezicelo
I-valve ye-butterfly eccentric kathathu ifanelekile kwizicelo ezahlukeneyo, kubandakanywa ioli kunye negesi, i-petrochemical, ukuveliswa kwamandla kunye namashishini okucoca.
Ukungalungi kweevalvu zebhabhathane eccentric kathathu
1. Iindleko eziphezulu
Ivalve yebhabhathane ye-eccentric eccentric ithande ukuba neendleko eziphezulu zokuqala zokwenziwa ngenxa yoyilo nolwakhiwo olukwinqanaba eliphezulu.
2. Ilahleko yentloko encinci
I-offset eyongezelelweyo kwi-triple eccentric design inokubangela ukulahlekelwa kwentloko ephezulu kancinane kune-valve eccentric ephindwe kabini.
Ivalve yebhabhathane ene-eccentric ephindwe kabini VS ivalve yebhabhathane ephindwe kathathu eccentric
1. Isihlalo seValve
Isihlalo sevalve yevalve yebhabhathane eccentric ifakwe kwigroove kwipleyiti yevalve kwaye yenziwe ngerabha efana ne-EPDM, ukuze ifikelele isitywina esingangeni moya, kodwa ayifanelekanga kwizicelo zobushushu obuphezulu.Isihlalo sevalvu yevalve yebhabhathane ephindwe kathathu iyintsimbi yonke okanye inamaleko amaninzi, ngoko ke ifanelekele kakhulu ubushushu obuphezulu okanye ulwelo oludlekayo.
2. Iindleko
Nokuba ziindleko zoyilo okanye ukuntsonkotha kwenkqubo yokwenziwa, iivalvu zebhabhathane eziphindwe kathathu ziphezulu kuneevalve zebhabhathane eziphindwe kabini.Nangona kunjalo, ukuphindaphinda emva kokugcinwa kweevalvu ezintathu ze-eccentric zingaphantsi kunezo ze-eccentric valves.
3. Itorque
Injongo yokuqala yoyilo lwevalve yebhabhathane eccentric kukunciphisa ngakumbi ukuguga kunye nokukhuhlane.Ke ngoko, itorque yevalve yebhabhathane eccentric kathathu incinci kunaleyo yevalve yebhabhathane ephindwe kabini.
