Kufotokozera mwatsatanetsatane njira yolondola yogwiritsira ntchito valve

Kukonzekera musanayambe ntchito

Musanagwiritse ntchito valve, muyenera kuwerenga mosamala malangizo ogwiritsira ntchito. Musanagwiritse ntchito, muyenera kukhala omveka bwino za kayendedwe ka gasi, muyenera kusamala kuti muwone zizindikiro zotsegula ndi kutseka kwa valve. Yang'anani maonekedwe a valavu kuti muwone ngati valavu ndi yonyowa, ngati pali chinyontho choyanika chithandizo; ngati apezeka kuti pali mavuto ena omwe akuyenera kuthetsedwa munthawi yake, sizidzagwiritsidwa ntchito molephera. Ngati valavu yamagetsi ikugwira ntchito kwa miyezi yoposa 3, clutch iyenera kufufuzidwa musanayambe, onetsetsani kuti chogwiriracho chili pamanja, ndiyeno yang'anani kutsekemera, chiwongolero ndi magetsi a magetsi.

Kugwiritsa Ntchito Moyenera kwa Mavavu Amanja

Ma valve opangidwa ndi manja ndi ma valve omwe amagwiritsidwa ntchito kwambiri, ndipo magudumu awo kapena zogwirira ntchito zimapangidwira motsatira mphamvu zaumunthu wamba, poganizira mphamvu ya malo osindikizira ndi mphamvu yotseka yofunikira. Choncho, simungagwiritse ntchito lever yaitali kapena dzanja lalitali kusuntha mbale. Anthu ena anazolowera kugwiritsa ntchito mbale dzanja, ayenera kulabadira kwambiri kutsegula kwa valavu ayenera kugwiritsidwa ntchito kukakamiza yosalala, kupewa mphamvu mopitirira muyeso, chifukwa kutsegula ndi kutseka valavu, mphamvu ayenera yosalala, osati zimakhudza. . Zina zotsegula ndi kutseka kwa ma valve othamanga kwambiri zimaganiziridwa kuti ndizokhudzidwa ndipo ma valve ambiri sangakhale ofanana ndi Gang.

Vavu ikatsegulidwa kwathunthu, gudumu lamanja liyenera kutembenuzidwira pang'ono, kuti ulusi pakati pa zolimba, kuti musamasule kuwonongeka. Zakuchuluka kwa ma valve owonjezera,kukumbukira mokwanira lotseguka ndi kutsekedwa kwathunthu pamene tsinde udindo, kupewa mokwanira lotseguka pamene zimakhudza akufa pakati. Ndipo n'zosavuta kuona ngati zili zachilendo pamene chatsekedwa kwathunthu. Ngati ofesi ya valve yatsekedwa, kapena chisindikizo cha spool pakati pa zinyalala zazikulu, malo otsekedwa bwino ayenera kusinthidwa. Kuwonongeka kwa valavu yosindikiza pamwamba kapena valve handwheel.

Chizindikiro chotseguka cha valve: valavu ya mpira,valavu ya butterfly yokhazikika, pulagi valavu tsinde pamwamba poyambira motsagana ndi tchanelo, kusonyeza kuti valavu pamalo otseguka kwathunthu; pamene tsinde la valavu likuzungulira 90 ° kumanzere kapena kumanja, poyambira ndi perpendicular kwa njira, kusonyeza kuti valavu mu malo otsekedwa kwathunthu. Mavavu ena a mpira, mavavu agulugufe, mavavu a pulagi kuti azigwetsera ndi tchanelo chofananira kuti atseguke, oyimirira kuti atseke. Ma valve a njira zitatu, zinayi ayenera kugwiritsidwa ntchito molingana ndi chizindikiro cha kutsegula, kutseka ndi kubwerera. Opaleshoniyo ikamalizidwa, chogwirira chosunthika chiyenera kuchotsedwa.

Kuchita bwino kwa ma cheki ma valve

Pofuna kupewa mphamvu yayikulu yomwe idapangidwa panthawi yotsekavalavu yokhala ndi mphira, valavu iyenera kutsekedwa mwamsanga, motero kuteteza mapangidwe a liwiro lalikulu la backflow, lomwe ndilo chifukwa cha kupanikizika kwamphamvu komwe kumapangidwira pamene valve imatsekedwa mwadzidzidzi. Chifukwa chake, liwiro lotseka la valve liyenera kufananizidwa bwino ndi kuchuluka kwa kuwonongeka kwa sing'anga yakumunsi.

Ngati kuthamanga kwa sing'anga yothamanga kumasiyana mosiyanasiyana, kuthamanga kwapakati kochepa sikukwanira kukakamiza chinthu chotseka kuti chiyime mokhazikika. Pankhaniyi, kuyenda kwa chinthu chotseka kumatha kuchepetsedwa mkati mwamtundu wina wake. Kugwedezeka kofulumira kwa chinthu chotseka kungapangitse kuti mbali zosuntha za valavu zithe msanga, zomwe zimapangitsa kuti ma valve awonongeke msanga. Ngati sing'anga ikugwedezeka, kugwedezeka kofulumira kwa chinthu chotseka kumayambitsidwanso ndi kusokonezeka kwakukulu kwapakati. Kulikonse kumene izi zili choncho, ma valve owunika ayenera kukhala pomwe kusokoneza kwapakatikati kumachepetsedwa.
