Umahluko phakathi kweValve yeBhola kunye neValve yeButterfly
Umahluko omkhulu phakathi kweevalvu zebhabhathane kunye neevalvu zebhola kukuba ivalvu yebhabhathane ivulwa okanye ivalwe ngokupheleleyo ngokusebenzisa idiski ngelixa ivalvu yebhola isebenzisa ibhola engenanto, eneembobo kunye nejikelezayo ukwenza loo nto. Zombini idiski yevalvu yebhabhathane kunye nomongo wevalvu yevalvu yebhola zijikeleza kwi-axis yazo. Ivalvu yebhabhathane inokulawula ukuhamba kwayo kwinqanaba layo elivulekileyo ngelixa ivalvu yebhola ingekho lula ukwenza oku.
Ivalvu yebhabhathane iphawulwa ngokuvula nokuvala ngokukhawuleza, isakhiwo esilula kunye nexabiso eliphantsi, kodwa ukuqina kwayo kunye nomthamo wokuthwala akulunganga. Iimpawu zeevalvu zebhola ziyafana nezo zeevalvu zesango, kodwa ngenxa yokunqongophala komthamo kunye nokumelana nokuvula nokuvala, kunzima ukuba ivalvu yebhola ibe yi-diameter enkulu.
Umgaqo wolwakhiwo lweevalvu zebhabhathane uzenza zifaneleke ngokukodwa ukwenziwa zibe zezo zinkulu ngobubanzi. Idiski yevalvu yebhabhathane ifakwe kwicala lobubanzi bombhobho. Kwindlela ye-cylindrical yomzimba wevalvu yebhabhathane, idiski ijikeleza i-axis. Xa ijikeleziswa ngekota, ivalvu ivuleke ngokupheleleyo. Ivalvu yebhabhathane inesakhiwo esilula, ixabiso eliphantsi kunye noluhlu olubanzi oluhlengahlengiswayo. Iivalvu zebhola zihlala zisetyenziselwa ulwelo kunye neegesi ezingenamasuntswana kunye nokungcola. Ezi valve zinokulahleka koxinzelelo lolwelo oluncinci, ukusebenza kakuhle kokuvala kunye nexabiso eliphezulu.
Xa kuthelekiswa, ukutywinwa kwevalvu yebhola kungcono kunevalvu yebhabhathane. Itywinwa yevalvu yebhola ixhomekeke ekucinezelweni komphezulu ongqukuva yisihlalo sevalvu ixesha elide, nto leyo ngokuqinisekileyo eza kugqitha ngokukhawuleza kunevalvu yesemi-ball. Ivalvu yebhola idla ngokwenziwa ngezinto eziguquguqukayo zokutywina, kwaye kunzima ukuyisebenzisa kwiipayipi zobushushu obuphezulu kunye noxinzelelo oluphezulu. Ivalvu yebhabhathane inesihlalo serabha, esikude kakhulu nokusebenza kwentsimbi eqinileyo yokutywina kweevalvu zesemi-ball, iivalvu zebhola kunye neevalvu zesango. Emva kokusetyenziswa ixesha elide kwevalvu yesemi-ball, isihlalo sevalvu siya kuguga kancinci, kwaye singasetyenziswa ngokuqhubekayo ngokulungiswa. Xa isiqu kunye nokupakisha zivuliwe kwaye zivaliwe, isiqu kufuneka sijikeleze kuphela ikota yokujika. Xa kukho naluphi na uphawu lokuvuza, cinezela ibolt yegland yokupakisha ukuze ubone ukuba akukho kuvuza. Nangona kunjalo, ezinye iivalvu azisetyenziswa kangako xa kuvuza kancinci, kwaye iivalvu zitshintshwa ngokuvuza okukhulu.
Kwinkqubo yokuvula nokuvala, ivalvu yebhola isebenza phantsi kwamandla okugcina izihlalo zevalvu kuzo zombini iziphelo. Xa kuthelekiswa nevalvu yesemi-ball, ivalvu yebhola inetorque enkulu yokuvula nokuvala. Kwaye okukhona ububanzi bayo bubukhulu, kokukhona umahluko phakathi kwetorque yokuvula nokuvala ubonakala ngakumbi. Ukuvulwa nokuvalwa kwevalvu yebhabhathane kuqatshelwa ngokoyisa ukuguquka kwerabha. Nangona kunjalo, kuthatha ixesha elide ukusebenzisa iivalvu zesango kunye neevalvu zeglobe kwaye kukwanzima ukwenza oko.
Ivalvu yebhola kunye nevalvu yeplagi zohlobo olufanayo. Yivalvu yebhola kuphela enebhola engenanto yokulawula ukuhamba kwayo. Iivalvu zebhola zisetyenziselwa ikakhulu ukusika, ukusasaza kunye nokutshintsha indlela yokuhamba kwesixhobo kwimibhobho.
