Umgaqo osebenzayo wentsimbi yentsimbi eneendlela ezintathu zevalve yebhola

1. Inkqubo yokuvula:

A. Kwindawo evaliweyo, ibhola icinezelwe ngokuchasene nesihlalo sevalve ngoxinzelelo lomatshini lwesiqu sevalve;

B. Xa i-handwheel ijikwa ngokuphambene, i-valve stem ihamba kwelinye icala, kwaye indiza ye-angular ezantsi yenza ibhola ikhululeke kwisihlalo sevalve;

C. Isiqu sevalve siyaqhubeka siphakamisa kwaye sisebenzisana nephini yesikhokelo kwi-spiral groove yesiqu sevalve, ukuze ibhola iqalise ukujikeleza ngaphandle kokukhuhlana;

D. Ide ifike kwindawo evuleke ngokupheleleyo, isiqu sevalve siphakanyiselwe kwindawo yomda, kwaye ibhola ijikeleza kwindawo evuleke ngokupheleleyo.

2. Inkqubo yokuvala:

A. Xa uvala, jika ivili lesandla ngokwewotshi, isiqu sevalve siqala ukuhla kwaye ibhola ishiya isihlalo sevalve ukuze iqalise ukujikeleza;

B. Qhubeka ujikelezisa i-handwheel, kwaye isiqu sevalve siya kushukunyiswa sisikhonkwane sesikhokelo esifakwe kwi-spiral groove kuyo, ukuze isiqu sevalve kunye nebhola ijikeleze i-90 ° ngaxeshanye;

C. Xa sele iza kuvala, ibhola iye yajikeleza i-90 ° ngaphandle kokudibana nesitulo sevalve;

D. Kumajiko-jiko ambalwa okugqibela evili lesandla, inqwelo-moya engumbhoxo ezantsi kwesiqu sevalve ijikela ngoomatshini kwaye icinezele ibhola ukuze icinezele ngokuqinileyo kwisitulo sevalve ukuze ifikelele itywina elipheleleyo.
