2. Tsinde la valve ndi ulusi wake wachikazi wokwera wawonongeka kapena mutu wa tsinde wathyoka kapenaMAVAVU A MPIRAtsinde lapindika:
Zifukwa: 1. Kugwiritsira ntchito molakwika, kukakamiza kwambiri pakusintha, kulephera kwa chipangizo chochepetsera, ndi kulephera kwa chitetezo chowonjezera. ; 2. Kuyika kwa ulusi kumakhala kotayirira kapena kothina kwambiri; 3. Kuchita zambiri komanso moyo wautali wautumiki
 
Chithandizo: 1. Sinthani ntchito, mphamvu yosapezeka ndi yayikulu kwambiri; yang'anani chipangizo chochepetsera, yang'anani chipangizo chotetezera chowonjezera; 2. Sankhani zinthu zoyenera, ndipo kulolerana kwa msonkhano kumakwaniritsa zofunikira; 3. Bwezerani zida zosinthira
 
Chachitatu, nsonga ya boneti imatuluka
 
Zifukwa: 1. Kusakwanira kwa bawuti kulimbitsa mphamvu kapena kupatuka; 2. Gasket sagwirizana ndi zofunikira kapena gasket yawonongeka; 3. Pamwamba pa olowa ndi cholakwika
 
Chithandizo: 1. Limbani mabawuti kapena pangani kusiyana kwa chivundikiro cha chitseko chofanana; 2. Bwezerani gasket; 3. Phatikizani ndi kukonza malo osindikizira a chitseko cha chitseko
Chachinayi, kutayikira kwamkati kwa valve:
 
Zifukwa: 1. Kutseka sikumangirira; 2. Malo olowa nawo awonongeka; 3. Kusiyana pakati pa valavu ndi tsinde la valavu ndi lalikulu kwambiri, zomwe zimapangitsa kuti valavu igwedezeke kapena kukhudzana bwino; 4. Zida zosindikizira ndizosauka kapena pakati pa valve ndi chodzaza.
 
Chithandizo: 1. Sinthani ntchito, kutsegulanso kapena kutseka; 2. Sulani valavu, pezaninso malo osindikizira apakati pa valve ndi mpando wa valve; 3. Sinthani kusiyana pakati pa pakati pa valavu ndi tsinde la valve kapena m'malo mwa disc valve; 4. Disani valavu kuthetsa kupanikizana; 5. Bwezeraninso kapena kuyika mphete yosindikizira
 
5. Pakati pa valve imasiyanitsidwa ndi tsinde la valve, zomwe zimapangitsa kuti kusinthaku kulephereke:
 
Zifukwa: 1. Kukonza kolakwika; 2. Zimbiri pamphambano ya valavu pachimake ndi valavu tsinde; 3. Mphamvu yosinthira yochulukirapo, yomwe imayambitsa kuwonongeka kwa mphambano pakati pa pachimake cha valve ndi tsinde la valve; 4. Vavu pachimake check gasket ndi lotayirira ndi kugwirizana gawo Valani
 
Chithandizo: 1. Samalani kuyang'anira panthawi yokonza; 2. Bwezerani ndodo yachitseko ya zinthu zosagwira dzimbiri; 3. Musatsegule valavu mwamphamvu, kapena pitirizani kutsegula valavu pambuyo poti ntchitoyo isatsegulidwe mokwanira; 4. Yang'anani ndikusintha zida zowonongeka
 
Chachisanu ndi chimodzi, pali ming'alu pakatikati pa valve ndi mpando wa valve:
 
Zifukwa: 1. Kusawoneka bwino kwa malo omangira; 2. Kusiyana kwakukulu kwa kutentha pakati pa mbali zonse za valve
 
Chithandizo: kukonza ming'alu, kutentha kutentha, kupukuta galimoto, ndikupera motsatira malamulo.
 
Zisanu ndi ziwiri, tsinde la valve sikugwira ntchito bwino kapena chosinthira sichisuntha:
 
Zifukwa: 1. Imatsekedwa molimba kwambiri pakazizira, ndipo imakula mpaka kufa ikatenthedwa kapena yothina kwambiri itatsegulidwa kwathunthu; 2. Kulongedza ndi kothina kwambiri; 3. Mpata wa tsinde la valve ndi wochepa kwambiri ndipo umakula; 4. Tsinde la valve lagwirizanitsidwa ndi nati Yolimba, kapena kuwonongeka kwa ulusi wofanana; 5. Chithokomiro chonyamula chimakondera; 6. Tsinde la khomo lapindika; 7. Kutentha kwapakati ndikwambiri, mafuta opaka ndi otsika, ndipo tsinde la valve lachita dzimbiri kwambiri.
 
Chithandizo: 1. Mutatha kutentha thupi la valve, yesetsani kutsegula pang'onopang'ono kapena kutsegula mokwanira ndi mwamphamvu ndikutsekanso; 2. Yesani tsegulani mutamasula chithokomiro; 3. Wonjezerani kusiyana kwa tsinde la valve moyenera; 4. Bwezerani tsinde la valve ndi waya Mkazi; 5. Konzani zonyamula zonyamula; 6. Wongola ndodo yachitseko, kapena isinthe; 7. Gwiritsani ntchito ufa woyera wa graphite ngati mafuta a ndodo ya pakhomo
 
Eyiti, kutulutsa kutayikira:
 
Zifukwa: 1. Zonyamula katundu ndizolakwika; 2. Chithokomiro chonyamula sichimakanizidwa kapena kukondera; 3. Njira yokhazikitsira kulongedza ndi yolakwika; 4. Pamwamba pa tsinde la valve ndi kuwonongeka
 
Chithandizo: 1. Sankhani zonyamula bwino; 2. Yang'anani ndikusintha chithokomiro cholongedza kuti muteteze kuponderezedwa; 3. Ikani zolongedzazo molingana ndi njira yoyenera; 4. Konzani kapena kusintha tsinde la valve
