Isakhiwo
Ubume beI-Palve yesango: II-Palve yesangoyiivalveEsebenzisa iplate yesango kunye nesitulo sevali ukulawula ukuvulwa nokuvala. II-Palve yesangoIbandakanya ikakhulu i-valve, isitulo se-valve, iplate yesango, i-valve stem, ikhava ye-valve, ileta yokupakisha, isambatho-Isondo, njl njl kuxhomekeke kutshintsho lwesihlobo phakathi kwesango kunye nesihlalo sevali, ubungakanani besitayile sinokutshintshwa kwaye ijelo linganqunyulwa. Ukuze uvale ivalve yesango ngokuqinileyo, iplate yesango kunye nesitulo sevali.
Ngokwemo eyahlukileyo yesakhiwo se-valve, i-valve yesango inokwahlulwa yangamacandelo amabini: Wedge kunye ne-parallel.
Ipleyiti yesango ye-Wedge Valve yesango ikwimo, kwaye umphezulu wokutywina unomdla kumgca we-chart yejelo. Umtshato phakathi kweplate yesango kunye nesitulo sevali sisetyenziselwa ukutywina (vala). Iplate ye-Wedge inokuba lisango elinye okanye isango eliphindwe kabini.
Umhlaba wokutywina we-valve yesango elifanayo lihambelana nomnye kwaye ugqithile kumgca wesitishi wejelo. Yahlulwe yangamanyathelo amabini: indlela evulekileyo kunye nendlela engavuniyo. Kukho isabatha esiphinana nendlela evulekileyo. Xa isango lisehlisa, imitshato yamasango amabini efanayo ixhasa amasango amabini kwisitulo sevali kwithambeka kwaye sinqumle ijelo lokuhamba. Xa isango liphakama kwaye livula, ifosholo kunye nesango lisebenzisana, isango linyukela ekuphakameni okuthile, kwaye iSango liqhutywa yiplate yesango eliphindwe kabini. Xa isango leplates kwisihlalo se-valve ecaleni kwendawo yokuhlala ezimbini ezifanayo, ingcinezelo yolwelo isetyenziselwa ukucinezela iplate yesango kwi-valve ekhupha i-valve.
Ngokweentshukumo ezahlukeneyo ze-valve xa kuvulwa isango kwaye kuvaliwe, ivalve yesango yahlulwe yangamacandelo amabini: i-valve yesango evulekileyo kunye ne-valve emnyama ye-bear kunye ne-valve emnyama. Xa i-valve stem neplastikhi yesango ye-valve yesango evulekileyo ivuliwe okanye ivaliwe, zivuka zize ziwe kwangaxeshanye; Xa i-Vove ye-valve yesango emnyama ivuliwe okanye ivaliwe, i-valve ijikelezwe, ukunyuka nokuwela isiqu se-valve akunakubonwa, kwaye ipleyiti iphakanyisiwe okanye iphantsi. Inzuzo ye-valve yesango evulekileyo kukuba ikwazi ukugweba ukuphakama kwejelo malunga nokuphakama kwesithuba se-valve, kodwa kunokusiqinisa ukuphakama kwexabiso. Xa ujongene nesandla-Isondo okanye ukuphatha, jika isandla-Isondo okanye ukuphatha ixesha lokuphamba, kwaye ivalve ivaliwe.
