Avalavundi gawo lowongolera mu dongosolo lobweretsera madzi, lomwe limagwira ntchito monga kusefukira, kusintha, kusinthasintha kosinthika, kupanikizika kapena kupsinjika kopitilira muyeso. Ma Vals omwe amagwiritsidwa ntchito poyendetsa madzi amadzimadzi osiyanasiyana kuchokera ku mavesi osavuta kwambiri ku mavuni osiyanasiyana omwe amagwiritsidwa ntchito mosiyanasiyana, ndi mitundu yosiyanasiyana yosiyanasiyana. Ma Valves angagwiritsidwe ntchito kuwongolera mitundu yosiyanasiyana yamadzi amlengalenga monga mpweya, madzi, nthunzi, zithunzi zotsika, matope, zitsulo zamadzimadzi ndi zojambula zamadzimadzi. Mafuta amagawidwanso ma valve ma valves, kuponyera ma valve achitsulo, mavalme achitsulo, chrome molybdenum chitsulo, mavuvu a mapulogalamu a mapulopulo, zinthu zina zokhala ndi zida malinga ndi zomwe zili. Zomwe zimafunikira kuyenera kukhala ndi chidwi ndi akagunda mavavu
1. Makina osokoneza bongo ndi magulu ayenera kukwaniritsa zofunikira za ma pipeliner
1.1 Chitsanzo cha valavu iyenera kuwonetsa zofunikira za mtundu wadziko lonse. Ngati ndi muyezo wokhazikika, malongosoledwe oyenera a mtunduwo ayenera kuwonetsedwa.
1.2 Kupanikizika kwamphamvu kwa valavu imafunikaChitaKupanikizika kwa mapaipi. Pansi pa malo osakhudza mtengo, kukakamizidwa komwe Valiva kumatha kupirira kuyenera kukhala kwakukulu kuposa kupanikizika kwenikweni kwa mapaipi; Mbali iliyonse ya valavu iyenera kuthana ndi 1.1 nthawi yogwira ntchito bwino kwambiri ngati valavu ikatsekedwa, osataya; Valavu ikatsegulidwa, thupi la valavu liyenera kupirira zofunikira za valavu.
1.3 Zopanga zopanga Vavvu, kuchuluka kwa dziko lapansi kumayenera kufotokozedwa. Ngati ndi muyezo wokhazikika, zolemba zakale ziyenera kulumikizidwa ndi mgwirizano wogula
2. Sankhani zinthu za valavu
2.1 Vomerezitsani zinthu zambiri, popeza matumbo achitsulo amalimbikitsidwa pang'onopang'ono, zomwe thupi la valavu limayenera makamaka chitsulo chowoneka, ndipo kalasi ndi kuyesa kwa mankhwala a kuponderezedwa kuyenera kuwonetsedwa.
2.2 avalavuZinthu za tsinde ziyenera kupangidwa ndi chitsulo chosapanga dzimbiri (2cr13), ndipo valavu yayikulu iyeneranso kukhala valve yolumikizidwa mu chitsulo chosapanga dzimbiri.
2.3 Mankhwala a mtedza amaponyera aluminiyamu mkuwa kapena kuponyera aluminimum thambo, ndipo kuuma kwake ndi nyonga zake ndizokulirapo kuposa gawo la valavu
2.4 Zinthu za valavu tsinde Bushing sikuyenera kukhala wopanda mphamvu komanso mphamvu zazikulu kuposa za stem ya valavu, ndipo siyiyenera kukhala yotupa ya valavu ya valavu, ndipo siyiyenera kukhala yotupa ya valavu ya valavu, ndi thupi la rave ndi thupi pansi pa kumiza madzi.
2.5 Zinthu za kusindikizidwa①Pali mitundu yosiyanasiyana yamavuvu, njira zingapo zosindikizira ndi zofunikira zakuthupi;②Ma vani wamba pachipata, njira, njira yosinthira, ndi njira yopukutira mphete yamkuwa iyenera kufotokozedwa;③Ma vani yachipata chofewa, zitsulo zopachikidwa pa valavu ya valavu yam'madzi, mankhwala ndi aukhondo;④Makunja a gulugufe ayenera kuwonetsa zinthu zomwe zili pamalo otetezera pachimake ndi zinthu za chipinda cha gulugufe; Malingaliro awo akuthupi ndi mankhwala, makamaka zofuna zaukhondo, magwiridwe antchito a arning ndikuvala kukana mphira; Eve rate ndi epdm mphira, etc.
2.6 Vath shaft①Chifukwa mavavu omwe ali paupakati nthawi zambiri amakhala otseguka ndipo atatsekedwa kangapo, kulongedza kumafunikira kuti tisagwiritse ntchito kwa zaka zingapo, ndipo kulongedza sikungakadali zaka zambiri, kuti tisunge zotsatira zanthawi yayitali;②Ma valve shaft kulongedza akuyeneranso kupirira kutseguka pafupipafupi ndikutseka, momwe mungasungireko ndi abwino;③Poona zofunikira pamwambapa, valavu yosanja yosanja siyiyenera kulowedwa m'malo mwa moyo kapena kupitilira zaka khumi;④Ngati kulongedwa kuyenera kusinthidwa, mapangidwe a valavu ayenera kuganizira njira zomwe zitha kusinthidwa motsogozedwa ndi madzi.
3. Bokosi losinthasintha
3.1 Zofunikira zapa thupi ndi zofunikira zakunja ndi zakunja ndizogwirizana ndi thupi la valavu. a
3.2 Bokosilo lizikhala ndi miyeso yoyang'ana, ndipo bokosilo limatha kupirira kumizidwa m'madzi atatu nditadutsa msonkhano. a

3.4 Kapangidwe ka nyumba yofalitsa ndi koyenera. Mukatseguka ndikutseka, imatha kuyendetsa shaft ya valavu kuti izungulira popanda kuyambitsa kusunthira mmwamba ndi pansi. a
3.5 Bokosi losinthika losinthika ndi chisindikizo cha valve sichingalumikizidwe munthawi yotsika. a
3.6 Palibe zinyalala m'bokosimo, ndipo zida zopondera zimayenera kutetezedwa ndi mafuta.
4.Valavumakina ogwiritsira ntchito
4.1 Malangizo otseguka ndi otseka a valavu ayenera kutsekedwa. a
4.2 Popeza mavamu omwe ali mu neipe ili nthawi zambiri amatsegulidwa ndikutsekedwa pamanja, kuchuluka kwa kutseguka ndi kutseka ndi kutsekeratu sikuyenera kukhala mkati mwa 200-600 kusinthana. a
4.3 Pofuna kuthandizira kutsegulidwa ndi kutsekedwa ndi munthu m'modzi, kutseguka kwakukulu ndi mtambo wotseka uyenera kukhala 240m-m pansi pa kupsinjika kwa mitengoyo.
4.4 Kutsegulidwa ndi kutseka kwa valavu kuyenera kukhala koloko ka lalikulu ndi miyeso yokhazikika ndikuyang'anitsitsa kuti anthu azitha kuziwongolera kuchokera pansi. Mavavu okhala ndi ma disc sayenera kuti ziweto zikhale zobisika. a
4.5 Sonyezani gulu la valavu yotseguka ndi digiri yotseka
①Mzere wa valavu yotseguka ndi kuyandikira kuyenera kuponyedwa pachikuto cha gearbox kapena pa chipolopolo cha ziwonetserozo pambuyo poti chitsogozo chizisinthidwa, ndipo mzere wozungulira uyenera kupakidwa ufa wa fluorests kuti uwonetsetse khungu; Pabwinobwino, mbale yachitsulo yopanda dzimbiri imatha kugwiritsidwa ntchito, apo ayi imapaka mbale yachitsulo, osagwiritsa ntchito khungu la aluminium kuti apange;③Singano yowoneka ndi maso ndikukhazikika mwamphamvu, pomwe kusintha kotseguka ndi kutseka ndikolondola, ziyenera kutsekedwa ndi ma Rivets. a
4.6 Ngativalavuamaikidwa m'manda, ndipo mtunda pakati pa makina ogwiritsira ntchito ndi gulu lowonetsera ndiChita15m Kuchokera pansi, payenera kukhala malo owonjezera, ndipo iyenera kukhazikitsidwa kuti anthu azitha kuwona ndikugwira ntchito kuchokera pansi. Ndiye kuti, kugwiritsa ntchito mavavuno mu network payipi sikuyenera kugwira ntchito.
5. ValavuKuyesedwa kwa magwiridwe antchito
5.1 Pamene valavu imapangidwa mumitundu ina, bungwe lovomerezeka liyenera kupatsidwa mwayi wochita izi:①Chimbudzi chotseguka komanso chotseka cha valavu yomwe ili ndi vuto lalikulu;②Pansi pa ntchito yogwira ntchito, nthawi zotseguka komanso zotsinditsera zomwe zingaonetsetse kuti valavu yatsekedwa mwamphamvu;③Kuzindikira kuti mumatha kuyamwa mu valavu yomwe ili pansi pamadzi obwera. a
5.2 Mayeso otsatirawa ayenera kuchitika valavu isanachotse fakitaleyo:①Valavu ikatsegulidwa, thupi la valavu imayenera kupirira kuyesa kwa kapangidwe kalikonse ka Valave;②Valavu ikatsekedwa, mbali zonse ziwiri ziyenera kukhazikika pa Valve, palibe kutaya; Koma valavu ya gulugufe wosindikizidwa, mtengo wopota si wokulirapo kuposa zofunikira
6. Anti wamkati ndi kunja kwa mavavu
6.1 mkati ndi kunja kwavalavuThupi (kuphatikiza bokosi losinthasintha liwiro) liyenera kuwombera kuti muchoke pamchenga ndi dzimbiri, ndipo yesetsani ma elercrostaly epoxy epoxy epoxy ya 0 ~ 3mm kapena kupitirira. Pakakhala zovuta kuzimitsa epoxy epoxy ya epoxy ya mavesi owonjezera, utoto wofanana wa epoxy uyeneranso kuthiridwa ndi kupopera mbewu.
6.2 mkati mwa thupi la valavu ndi ziwalo zonse za valavu imafunikira kuti ikhale yotsutsa. Mbali imodzi, si dzimbiri lomwe silidzanyowa m'madzi, ndipo palibe kuphukira kwamadzi komwe kumachitika pakati pa zitsulo ziwiri; Kumbali inayo, nkhope ndizosalala kuchepetsa madzi. a
6.3 Zofunikira za ukhondo wa anti-Corrosion epoxy remin kapena utoto mu thupi la valavu kuyenera kukhala ndi mbiri yoyeserera yolingana. Mankhwala ndi zinthu zakuthupi ziyeneranso kukumana ndi zofunikira
7. Makina oyendetsa ndi mayendedwe
7.1 mbali zonse ziwiri za valavu idzasindikizidwa ndi mbale zowunikira. a
Ziphuphu zamitundu iwiri kapena yaying'ono.
Zitsulo zazikuluzikulu zazitali zimaphatikizidwanso ndi mtengo wosavuta kuti mupewe kuwonongeka panthawi yoyendera
8. Onani buku la fakitale la valavu
8.1 Vala ndi zida, ndipo izi zili bwino ziyenera kuwonetsedwa mu buku la fakitale: Valani Valani Mavalidwe; chitsanzo; kukakamizidwa; muyezo wopanga; Valavuni thupi; valavu ya valavu; zinthu zosindikizira; Zipangizo zotchinga; valavu ya ngalande ya psem; Zonyansa zotsutsana; malangizo oyambira; kusintha; kutsegulira ndi kutsimikiza mtima mokakamizidwa;
8.2 Dzina laMasewera a TVwopanga; tsiku lopanga; chiwerengero cha fakitale: Kunenepa; mawonekedwe, chiwerengero cha mabowo, ndi mtunda pakati pa mabowo a pakati pa kulumikizananyamulaakuwonetsedwa mu chithunzi; Miyeso ya kutalika konse, m'lifupi, ndi kutalika; nthawi yotseguka komanso yotseka; Valavu ikukanika polimbana ndi kokwanira; Zambiri zoyenerera za valve ex-kufufuza kwa mafakitale ndi kusamala kuti mukhazikitsidwe ndikukonza, etc.
