A: Ukuqala koku kusilela koku kusilela kwivalve. Ukuba i-disve ye-valve iwe ngaphakathi kwe heam verator ye-steam, iya kuthintela itshaneli yokuhamba kwegesi eshushu. Isisombululo kukuvula i-valve gland ukulungisa, okanye ukutshintsha ivalve engaphumelelanga. Ithuba lesibini kukuba kukho irhasi enkulu kwitanki yokuqokelela itanki, ebonisa umbhobho. Isisombululo kukuvula izixhobo zokuphelisa ezibekiweyo kwinkqubo yomoya, enjengomnyango we-radiator kwitanki yokuqokelelwa kwegesi, njl njl. Zimbini iindlela eziphambili zokufumana imibhobho evaliweyo: Toundanga kunye namanzi. Indlela yokuchukumisa ngesandla kukuba apho iqondo lobushushu liphantsi, kukho ingxaki. Indlela yokukhupha amanzi kukukhupha icandelo lamanzi ngecandelo, kwaye lidlule amanzi embindini wemibhobho eyahlukeneyo. Ukuba amanzi kwelinye icala ayaqhubeka nokuhamba phambili, akukho ngxaki malunga noku; Ukuba ibuyela emva emva kokuhamba okwethutyana, oko kuthetha ukuba esi siphelo sivaliwe, sidibanise eli candelo lombhobho kwaye likhuphe ibhloko.
IXESHA LOKUQALA: APR-21 ukuya kwi-2123
