¢ Ù Kuyesa mphamvu kwa valavu yachitetezo ndi yofanana ndi ma valve ena. Poyesa gawo lapansi la thupi la valve, kupanikizika kumayambitsidwa kuchokera ku I = I kutha, ndipo malo osindikizira amatsekedwa; Poyesa kumtunda kwa thupi la valve ndi chivundikiro cha valve, kupanikizika kumayambitsidwa kuchokera kumapeto kwa El, ndipo mapeto ena amatsekedwa. Thupi la valve ndi chivundikiro ndi oyenerera ngati palibe kutayikira mkati mwa nthawi yotchulidwa.
¢ Ú Kuyesa kusindikiza ndikuyesa kukakamiza kosalekeza, kugwiritsa ntchito sing'anga ndi: valavu yotetezera nthunzi yokhala ndi nthunzi yodzaza ngati njira yoyesera; Vavu ya ammonia kapena mpweya wina umagwiritsa ntchito mpweya ngati njira yoyesera; Mavavu amadzi ndi zakumwa zina zosawononga zimagwiritsa ntchito madzi ngati njira yoyesera. Kwa ma valve ena ofunikira otetezera, nayitrogeni imagwiritsidwa ntchito ngati njira yoyesera.
Mayeso osindikizira adzachitidwa ndi mtengo wamtengo wapatali monga kukakamiza kwa mayesero, ndipo chiwerengero cha nthawi sichidzakhala chocheperapo ziwiri, ndipo chimakhala choyenera ngati palibe kutayikira mkati mwa nthawi yotchulidwa. Pali njira ziwiri zowonera kutayikira: imodzi ndiyo kusindikiza zolumikizira za valavu yotetezera, kuyika chisindikizo chochepa kwambiri cha pepala pa El flange ndi batala, kuphulika kwa pepala kopyapyala ndikutuluka, ndipo winayo ndi woyenerera; Chachiwiri, gwiritsani ntchito batala kuti musindikize mbale yopyapyala ya pulasitiki kapena mbale zina pamunsi pa chotulukapo, mudzaze madzi kuti musindikize valavu ya valve, ndipo onetsetsani kuti madziwo sakuphulika ngati oyenerera. Chiwerengero cha kupanikizika kosalekeza ndi kuyesanso kuyesa kupanikizika kwa valve yotetezera sikungakhale kosachepera 3 nthawi, ndipo ndi yoyenerera ngati ikukwaniritsa zofunikira. Onani njira zoyesera za GB / T 12242 1989 zama mavavu otetezedwa pamayesero osiyanasiyana achitetezo
