Umahluko phakathi kweValve yeBhola kunye neButterfly Valve
Owona mahluko mkhulu phakathi kweevalve zebhabhathane kunye neevalve zebhola kukuba ivalve yebhabhathane ivuleke ngokupheleleyo okanye ivalwe ngokusebenzisa idiski ngelixa ivalve yebhola isebenzisa umngxuma, oqholiweyo kunye nebhola ejikelezayo ukwenza oko.Zombini idiski yevalve yebhabhathane kunye nombindi wevalve yevalve yebhola zijikeleza iaxis yazo.Ivalve yebhabhathane inokulawula ukuhamba ngeqondo layo elivulekileyo ngelixa ivalve yebhola ingafanelekanga ukwenza oku.
I-valve ye-Butterfly ibonakaliswe ngokuvula ngokukhawuleza kunye nokuvala, isakhiwo esilula kunye neendleko eziphantsi, kodwa ukuqina kwayo kunye nomthamo wokuthwala akulungile.Iimpawu zeebhola zebhola zifana nezo ze-valve zesango, kodwa ngenxa yokunciphisa umthamo kunye nokuvula kunye nokuvala ukuchasana, kunzima ukuba i-valve yebhola ibe yi-diameter enkulu.
Umgaqo wokwakhiwa kweevalve zebhabhathane ubenza ukuba bafaneleke ngokukodwa ukuba zenziwe zibe yi-diameter enkulu.I-disc yevalve yebhabhathane ifakwe kumda wecala lombhobho.Kwi-cylindrical passage ye-butterfly valve body, i-disc ijikeleza i-axis.Xa ijikeleziswa ikota, ivalve ivuleke ngokupheleleyo.Ivalve yebhabhathane inesakhiwo esilula, ixabiso eliphantsi kunye noluhlu oluguquguqukayo olubanzi.Iivalvu zebhola zidla ngokusetyenziselwa ulwelo kunye neegesi ngaphandle kwamaqhekeza kunye nokungcola.Ezi zivalo zinelahleko encinci yoxinzelelo lwamanzi, ukusebenza kakuhle kokutywinwa kunye neendleko eziphezulu.
Xa kuthelekiswa, ukutywinwa kwevalve yebhola kungcono kunevalve yebhabhathane.Ukutywinwa kwevalve yebhola kuxhomekeke kumphezulu we-spherical ngesihlalo sevalve ixesha elide, eliqinisekileyo lokunxiba ngokukhawuleza kunevalve ye-semi-ball.Ivalve yebhola ngokuqhelekileyo yenziwe ngezinto zokutywina eziguquguqukayo, kwaye kunzima ukuyisebenzisa kwiqondo lokushisa eliphezulu kunye nemibhobho yoxinzelelo oluphezulu.Ivalve yebhabhathane inesihlalo serabha, esikude nentsimbi eqinileyo yokutywina ukusebenza kweevalve zesemi-ball, iivalve zebhola kunye neevalvu zesango.Emva kokusetyenziswa kwexesha elide levalve ye-semi-ball, isihlalo sevalve siya kunxitywa kancinci, kwaye sinokusetyenziswa ngokuqhubekayo ngohlengahlengiso.Xa isiqu kunye nokupakishwa kuvulwa kwaye kuvaliwe, isiqu sidinga kuphela ukujikeleza ikota.Xa kukho naluphi na uphawu lokuvuza, cofa ibholithi yedlala lokupakisha ukuze uqonde ukuba akukho kuvuza.Nangona kunjalo, ezinye iivalve zisasetyenziswa ngokuncinci ukuvuza okuncinci, kwaye iivalvu zitshintshwa ngokuvuza okukhulu.
Kwinkqubo yokuvula nokuvala, i-valve yebhola isebenza phantsi kwamandla okubambisa izihlalo zevalve kuzo zombini iziphelo.Xa kuthelekiswa nevalve yesiqingatha sebhola, ivalve yebhola inetorque enkulu yokuvula nokuvala.Kwaye inkulu i-diameter ye-nominal, i-torque ecacileyo ngakumbi yokuvula kunye nokuvala i-torque.Ukuvulwa kunye nokuvalwa kwevalve yebhabhathane kufezekiswa ngokunqoba i-deformation yerubha.Nangona kunjalo, kuthatha ixesha elide ukusebenzisa iivalvu zesango kunye neevalvu zeglowubhu kwaye kukwangumsebenzi ukwenza oko.
Ivalve yebhola kunye nevalve yeplagi zezohlobo olufanayo.yivalve yebhola kuphela enebhola enomngxuma yokulawula ukuhamba kuyo.Iivalvu zebhola zisetyenziswa ikakhulu ukusika, ukusasaza kunye nokutshintsha indlela yokuhamba kwephakathi kwimibhobho.
