4, ivalvu yeglobhu: ibhekisa kwiindawo zokuvala (idiski) ecaleni komgca osembindini wentshukumo yesihlalo sevalvu. Ngokwemo yokuhamba kwediski, utshintsho lokuvulwa kwesihlalo sevalvu luhambelana ngqo nokubetha kwediski. Ngenxa yolu hlobo lwevalvu, i-open or close stem stroke imfutshane, kwaye inomsebenzi wokunqunyulwa othembekileyo kakhulu, kwaye ngenxa yotshintsho lokuvulwa kwesihlalo sevalvu kunye nokubetha kwediski kuyafana ngokuthe ngqo, kufanelekile kakhulu kulawulo lokuhamba. Ke ngoko, olu hlobo lwevalvu lunovelwano kakhulu ekusikeni okanye ekulawuleni nasekuqhobosheni.
Iingenelo:
(1) Kwinkqubo yokuvula nokuvala, ngenxa yokungqubana phakathi kwediski kunye nomzimba wevalvu, umphezulu wokutywina umzimba umncinci kunevalvu yesango, ngoko ke ukumelana nokuguguleka.
② Ukuphakama kokuvula ngokubanzi yi-1/4 yetshaneli yesihlalo sevalvu, ngoko ke incinci kakhulu kunevalvu yesango;
(3) Ngokuqhelekileyo kukho umphezulu omnye wokutywina emzimbeni wevalvu kunye nediski, ngoko ke inkqubo yokuvelisa ingcono, kulula ukuyigcina;
④ Njengoko isizalisi sidla ngokuba ngumxube we-asbestos kunye ne-graphite, sinomgangatho wokumelana nobushushu obuphezulu. Iivalvu zomphunga eziqhelekileyo zisetyenziswa yivalvu yeglobe.
Iingxaki:
(1) Ngenxa yokuba indlela yokuhamba kwesixhobo esidlula kwivalvu itshintshile, ngoko ke ukumelana nokuhamba okuncinci kwevalvu yehlabathi kuphezulu kunezinye iintlobo ezininzi zeevalvu;
② Ngenxa yokubetha ixesha elide, isantya sokuvula sicotha kunevalvu yebhola.
