Isiseko sokuKhetha iValve kunye neziKhokelo I

Kule mihla, kukho iivalvu ezininzi ngakumbi kwiimarike. Iindidi zeevalvu zinzima ngokukodwa, kwaye isakhiwo kunye nezinto eziphathekayo nazo zihluke. Ukukhethwa kweevalve kubaluleke kakhulu ekusebenzeni kwexesha elide lesixhobo kwiimeko zokusebenza. Ukukhetha okungafanelekanga kweevalvu kunye nokungazinzi kwabasebenzisi kwiivalvu ngumthombo weengozi kunye nezoyikiso zokhuseleko. Nangona kunjalo, kuluntu lwanamhlanje, imfuno yeemveliso zevalvu ixhaphake ngakumbi kushishino. Abasebenzisi kufuneka babe nokuqonda ngakumbi kunye nokuqatshelwa kolwazi lweevalvu kunye neminye imiba. Zimbini iindidi zeempawu zevalvu, iimpawu zenkonzo kunye neempawu zesakhiwo. Ukusetyenziswa kweempawu: Inquma ukusebenza okuphambili kunye nobubanzi bokusetyenziswa kwe-valve, ehambelana neempawu ze-valve: iindidi ze-valve (i-valve evaliweyo, i-valve elawulayo, i-valve yokhuseleko, njl.); iintlobo zemveliso (iivalvu zesango, iivalve zeglowubhu, iivalve zebhabhathane, iivalve zebhola, njl.); iindawo eziphambili zevalve (umzimba wevalve, isigqubuthelo, isiqu, idiski, umphezulu wokutywina) izinto; imowudi yothumelo lwevalvu, njl njl. Iimpawu zesakhiwo: Imisela iimpawu zesakhiwo sofakelo lwevalvu, ukugcinwa kunye nezinye iindlela. Kungokweempawu zesakhiwo se-valve: ubude kunye nobude obupheleleyo be-valve, ifom yokudibanisa kunye nombhobho (uxhulumaniso lwe-flange, uxhulumaniso lwe-threaded, uxhumano lwe-clamp, uxhulumaniso lwentambo yangaphandle, uxhumano lwe-welding end, njl.); imo yokutywina (isangqangi, isangqa esinentambo, i-surfacing, i-welding yokutshiza, i-valve body); Isakhiwo sentonga (intonga ejikelezayo, intonga yokuphakamisa) kunye nokunye.
