Umahluko phakathi kweValve yeButterfly eHlalisweyo neValve yeButterfly eHlalisweyo eneMetal
Iivalvu zebhabhathane, zinesakhiwo esincinci, uyilo olulula, ukusebenza kakuhle, kunye nokugcinwa okulula.
Zezinye zeevalvu zoshishino ezidumileyo.
Ngokwesiqhelo sineevalvu zeebhabhathane ezihlala ziqinile, okanye iivalvu zeebhabhathane ezifakwe ngerabha. Kule klasi, sineevalvu zeebhabhathane ezifakwe ngerabha yerabha ye-wafer, iivalvu zeebhabhathane ezifakwe ngerabha yelug, iivalvu zeebhabhathane ezifakwe ngerabha ye-U kunye neevalvu zeebhabhathane ezifakwe ngerabha yeflange ephindwe kabini.
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.
Ivalvu yebhabhathane ephindwe kathathu
Zombini iindawo zokutywina zevalvu zizinto zesinyithi okanye ezinye izinto eziqinileyo, ezingenawo umsebenzi omhle wokutywina, kodwa zineempawu ezintle zoomatshini, ezifana nokumelana nobushushu obuphezulu kunye nokungagugi.
Ngokubanzi, kukho umahluko olandelayo kwiivalvu zebhabhathane zezihlalo ezimbini ezahlukeneyo.
<1> Ulwakhiwo olwahlukileyo
Uyilo lomgca ophakathi wevalvu yebhabhathane ehleli phantsi ekwaziyo ukumelana nobunzima ngelixa uyilo oluphindwe kabini okanye kathathu oluyi-eccentric lwevalvu yebhabhathane ehleli phantsi yesinyithi.
<2> Ubushushu obahlukeneyo obufanelekileyo
Sisebenzisa ivalvu yebhabhathane ehleli phantsi ekwaziyo ukumelana nobushushu obuqhelekileyo, ngelixa ivalvu yebhabhathane ehleli phantsi esetyenziswa kwiqondo lobushushu eliphantsi, eliqhelekileyo neliphezulu.
<3> Uxinzelelo olwahlukileyo
Ivalvu yebhabhathane ehleli phantsi ekwaziyo ukumelana noxinzelelo oluphantsi noluqhelekileyo kwaye ivalvu yebhabhathane ehleli phantsi ensimbi ingafanela noxinzelelo oluphakathi noluphezulu.
<4> Ukusebenza okwahlukileyo kokutywina
Ivalvu yebhabhathane ehleli phantsi ekwaziyo ukumelana nemozulu kunye nevalvu yebhabhathane ehleli phantsi yentsimbi zisebenza kakuhle xa zitywinwa. Ivalvu yebhabhathane ehleli phantsi ingavalwa kakuhle xa kuxinezelekile kwaye kubushushu obuphezulu.
