Inzuzo
1. Kuyinto elula futhi esheshayo ukuvula nokuvala, ngokumelana okuphansi koketshezi nokusebenza okulula.
2. Isakhiwo esilula, usayizi omncane, ubude besakhiwo esifushane, ivolumu encane, isisindo esincane, esifanele i-valve enkulu esezingeni eliphakeme.
3. Ingahambisa udaka futhi igcine uketshezi oluncane emlonyeni wepayipi.
4. Ngaphansi kwengcindezi ephansi, ukubekwa uphawu okuhle kungatholakala.
5. Ukusebenza okuhle komthethonqubo.
6. Lapho isihlalo se-valve sivulekile ngokuphelele, indawo yokugeleza esebenzayo yesiteshi sesihlalo se-valve inkulu futhi ukumelana noketshezi kuncane.
7. I-torque yokuvula nokuvala incane, ngoba izingcwecwe zovemvane ezinhlangothini zombili zeshaft ejikelezayo ngokuyisisekelo ziyalingana komunye nomunye ngaphansi kwesenzo esiphakathi, futhi ukuqondiswa kwetorque kuyaphikisana, ngakho-ke kulula ukuvula nokuvala.
8. Izinto zokuvala uphawu ngokuvamile ziyirabha nepulasitiki, ngakho-ke ukusebenza kokufakwa uphawu kwengcindezi ephansi kuhle.
9. Kulula ukufaka.
10. Ukusebenza kuguquguquka futhi konga abasebenzi. Izandla ezenziwa ngesandla, ngogesi, nge-pneumatic nange-hydraulic zingakhethwa.
ukusilela
1. Ububanzi bokucindezela nokusebenza kokushisa okusebenzayo kuncane.
2. ukubekwa uphawu kabi.
I-butterfly valve ingahlukaniswa nge-offset plate, ipuleti emile, ipuleti ethambekele nohlobo lwe-lever.
Ngokuya ngefomu lokufaka uphawu, kungaba uhlobo lokuthambisa oluthambile nohlobo lokuvala kanzima. Uhlobo lwesithambile oluthambile ngokuvamile lisebenzisa uphawu lwenjoloba yenjoloba, kanti uhlobo lwensimbi elukhuni luvame ukusebenzisa uphawu lwensimbi.
Ngokuya ngohlobo lokuxhuma, lingahlukaniswa ngoxhumo lwe-flange nokuxhumeka kocingo; ngokuya ngemodi yokudlulisa, ingahlukaniswa ngebhukwana, ukuhanjiswa kwegiya, umoya womoya, umfutholuketshezi kanye nogesi.
