l Varuvhu yetsono imhando yevharuvhu inogadziriswa, iyo inoshandiswa zvakanyanya, sekucheka kureba kwekucheka murazvo, uye knob yekugadzirisa kupisa kwemoto ivhavhavha yetsono. Tsono vharafu chikamu chakakosha chekuyera kwepipeline system, iyo inonyanya kusanganisira globe valve uye bhora vharafu. Basa rayo nderekuvhura kana kucheka pombi. Tsono vharafu spool ikoni yakapinza kwazvo, kunge tsono inopinzwa pachigaro, ndosaka zita.
l Stop valve, inozivikanwawo sevhavha yekuvhara-vhavha, ivhavha yekuvhara yakamanikidzwa, saka kana valve yakavharwa, kumanikidzwa kunofanira kushandiswa kune disc kudzivirira kubuda kwechisimbiso chekumanikidzirwa. Kana iyo yepakati ichipinda muvharuvhu kubva pasi pevhavha disc, kushorwa kunofanirwa kukundwa nesimba rekushanda ndiko kukakavara pakati pehunde uye kurongedza uye kukanda kunoitwa nekumanikidza kwepakati. Simba rekuvhara vharuvhu rakakura kudarika iro rekuvhura vharuvhu, saka dhayamita yetsinde inofanira kunge yakakura, kana zvisina kudaro dzinde richakotama.
l Kuisa precautions
1. Nzvimbo yekuisa, kureba uye nzira yekupinza uye yekubuda inofanira kusangana nezvinodiwa zvekugadzira. Nzira yekuyerera kwepakati ichaenderana negwara remuseve wakatarwa pamutumbi wevharuvhu, uye kubatana kuchave kwakasimba uye kwakasimba.
2. Ivhavha inofanira kuongororwa nemaziso isati yaiswa, uye ndiro yezita revhavha inofanira kuenderana nemitemo yemazuva ano yenyika "general valve marks" GB 12220. Nokuda kwevhavha ine simba rekushanda rinopfuura 1.0 MPa uye kucheka-kubvisa basa pane pombi huru, kuedza kwesimba uye kusimba kuchaitwa kusati kwaiswa, uye valve inogona kushandiswa chete mushure mokunge yakwanisa. Munguva yekuyedzwa kwesimba, kudzvanywa kweyedzo kuchave 1.5 nguva dzezita rekumanikidza, nguva yacho haingave isingasviki 5min, uye goko revhavha uye kurongedza zvichave zvinokodzera kana pasina kuvuza. Munguva yekuyedza kusimba, kudzvanywa kweyedzo ndeye 1.1 nguva dzezita rekumanikidza, uye nguva yekuyedza inosangana nezvinodiwa zveGB 50243.
