Momwe mungagwiritsire ntchito valavu molondola ndiyenera kutolera!

Vavu ndi chipangizo chomwe chimagwiritsidwa ntchito poyang'anira njira, kuthamanga ndi kutuluka kwa madzimadzi mumadzimadzi.Ndi chipangizo chomwe chimapangitsa sing'anga (madzi, gasi, ufa) kuyenda kapena kuyimitsa mu mapaipi ndi zida ndipo imatha kuwongolera kuyenda kwake.Valavu ndi gawo lofunikira lowongolera mumayendedwe amadzimadzi.
Kukonzekera musanayambe ntchito
Werengani malangizo ogwiritsira ntchito mosamala musanagwiritse ntchito valve.Musanayambe kugwira ntchito, njira yoyendetsera gasi iyenera kukhala yomveka bwino, ndipo zizindikiro zotsegula ndi kutseka ziyenera kufufuzidwa.Yang'anani maonekedwe a valve kuti muwone ngati ili yonyowa.Ngati ili yonyowa, iyenera kuumitsidwa;ngati pali vuto lina lililonse, liyenera kuthetsedwa munthawi yake, ndipo palibe ntchito yolakwika yomwe imaloledwa.Ngati valavu yamagetsi yayimitsidwa kwa miyezi yoposa 3, clutch iyenera kufufuzidwa musanayambe, ndipo kutsekemera, chiwongolero ndi magetsi oyendetsa galimoto ayenera kufufuzidwa pambuyo potsimikizira kuti chogwiriracho chili pamanja.
Njira yolondola yogwiritsira ntchito valve yamanja
Valve yamanja ndi valve yogwiritsidwa ntchito kwambiri, gudumu lake lamanja kapena chogwirira chimapangidwa molingana ndi wamba wamba, poganizira mphamvu ya malo osindikizira ndi mphamvu yotseka yofunikira.Chifukwa chake, lever yayitali kapena sipinari yayitali singagwiritsidwe ntchito kusuntha.Anthu ena azolowera kugwiritsa ntchito sipinari, ndipo ayenera kusamala kwambiri.Potsegula valavu, mphamvuyo iyenera kukhala yokhazikika kuti ipewe mphamvu zambiri, zomwe zimapangitsa kuti valve itsegule ndi kutseka.Mphamvuyo iyenera kukhala yokhazikika osati kukhudza.Magawo ena a ma valve othamanga kwambiri omwe amatsegula ndi kutseka amawona kuti mphamvu yake sifanana ndi ma valve wamba.
Vavu ikatsegulidwa kwathunthu, gudumu la m'manja liyenera kutembenuzidwa pang'ono kuti ulusi ukhale wolimba kuti zisawonongeke komanso kuwonongeka.Pa ma valve okwera tsinde, kumbukirani momwe tsinde lilili lotseguka komanso lotsekedwa mokwanira, kuti musamenye chapakati chakufa mukatsegula.Ndikwabwino kuti muwone ngati zili zachilendo mukatsekedwa kwathunthu.Ngati valavu ikugwa, kapena chisindikizo cha valve pakati pa zinyalala zazikulu zomwe zaikidwa, malo otsekedwa bwino a valve adzasintha.Kuwonongeka kwa ma valve pamwamba kapena kuwonongeka kwa magudumu.
Chizindikiro chotsegulira valavu: pamene poyambira pamwamba pa tsinde la valavu ya valavu ya mpira, valavu ya butterfly ndi valavu ya pulagi ikufanana ndi njira, zimasonyeza kuti valavu ili pamalo otseguka;pamene tsinde la valve likuzungulira kumanzere kapena kumanja ndi 90. Groove ndi perpendicular kwa njira, kusonyeza kuti valavu ili pamalo otsekedwa kwathunthu.Vavu ina ya mpira, valavu ya butterfly, valavu ya pulagi yokhala ndi wrench ndi njira yofananira kuti itseguke, yoyima kuti itseke.Kugwira ntchito kwa ma valve a njira zitatu ndi zinayi kudzachitidwa molingana ndi zizindikiro za kutsegula, kutseka ndi kubweza.Chotsani chogwirizira chosunthika mukatha ntchito.
Njira yolondola yogwiritsira ntchito valve yotetezera
Valve yachitetezo yadutsa mayeso okakamiza komanso kupanikizika kosalekeza musanayike.Pamene valavu yotetezera imayenda kwa nthawi yaitali, wogwira ntchitoyo ayenera kumvetsera kuti ayang'ane valavu yotetezera.Poyang'ana, anthu ayenera kupeŵa kutulutsa valavu yotetezera chitetezo, kuyang'ana chisindikizo cha valavu yachitetezo, kukokera valavu yotetezera ndi wrench ndi dzanja, kutsegula kamodzi pakapita nthawi kuti achotse dothi ndikutsimikizira kusinthasintha kwa valve yotetezera.
Njira yoyenera yogwiritsira ntchito valavu ya drainage
Valavu yokhetsa ndiyosavuta kutsekedwa ndi madzi ndi zinyalala zina.Mukayamba, choyamba tsegulani valavu yothamangitsira ndikutsuka payipi.Ngati pali chitoliro chodutsa, valavu yodutsa imatha kutsegulidwa kuti iwonongeke kwakanthawi kochepa.Kwa valve yokhetsa popanda chitoliro chothamangitsira ndi chitoliro chodutsa, valavu yokhetsa imatha kuchotsedwa.Pambuyo potsegula zitsulo zodulidwa, tsekani valavu yotseka, ikani valavu yowonongeka, ndiyeno mutsegule valavu yodula kuti muyambe kukhetsa.
Kuchita bwino kwa valve yochepetsera kuthamanga
Musanayambe valavu yochepetsera kuthamanga, valavu yodutsa kapena valavu yothamanga iyenera kutsegulidwa kuti iyeretse dothi mupaipi.Pambuyo pothamangitsidwa, valavu yodutsa ndi valavu yothamanga idzatsekedwa, ndiyeno valavu yochepetsera mphamvu idzayambika.Pali valavu yotsegulira kutsogolo kwa valve yochepetsera mpweya, yomwe imayenera kutsegulidwa poyamba, kenaka mutsegule pang'ono valavu yotseka kumbuyo kwa valve yochepetsera mphamvu, ndipo potsiriza mutsegule valavu yodulira kutsogolo kwa valve yochepetsera mphamvu. .Kenako, yang'anani miyeso yamagetsi isanayambe komanso itatha valavu yochepetsera kuthamanga, ndipo sinthani chowongolera cha valavu yochepetsera mphamvu kuti chiwongolero chakumbuyo kwa valve chifike pamtengo wokonzedweratu.Kenaka mutsegule pang'onopang'ono valavu yotseka kumbuyo kwa valve yochepetsera kuthamanga kuti mukonze kupanikizika kumbuyo kwa valve mpaka kukhutiritsa.Konzani wononga yosinthira ndikuphimba chipewa choteteza.Mwachitsanzo
Ngati valve yochepetsera mphamvu ikulephera kapena ikufunika kukonzedwa, valavu yodutsa iyenera kutsegulidwa pang'onopang'ono, ndipo valavu yodulidwa kutsogolo kwa valve iyenera kutsekedwa nthawi yomweyo.Valavu yodutsa iyenera kusinthidwa pang'onopang'ono kuti ipangitse kupanikizika kumbuyo kwa valve yochepetsera mphamvu kukhala yokhazikika pamtengo wokonzedweratu.Kenaka tsekani valavu yochepetsera kuthamanga, sinthani kapena konzani, kenaka mubwerere mwakale.
Kuchita bwino kwa valavu yoyendera
Pofuna kupewa mphamvu yamphamvu yomwe imapangidwa panthawi yomwe valavu yotsekera yatsekedwa, valve iyenera kutsekedwa mwamsanga, kuti ateteze mapangidwe a backflow velocity, omwe ndi chifukwa cha kupanikizika kwamphamvu pamene valve imatsekedwa mwadzidzidzi. .Chifukwa chake, liwiro lotseka la valavu liyenera kufanana ndi kutsika kwa sing'anga yakumunsi molondola.
Ngati liwiro la sing'anga yotsika ndi yayikulu, liwiro locheperako silikwanira kukakamiza kutseka kuyimitsa mokhazikika.Pachifukwa ichi, kusuntha kwa gawo lotseka kumatha kuletsedwa ndi damper mkati mwamtundu wina wa sitiroko yake.Kugwedezeka kofulumira kwa zigawo zotsekera kumapangitsa kuti zigawo zosuntha za valve zizivala mofulumira, zomwe zimapangitsa kuti valve iwonongeke msanga.Ngati sing'anga ikuthamanga, kugwedezeka kofulumira kwa gawo lotseka kumayambitsidwanso ndi kusokonezeka kwakukulu kwapakati.Pachifukwa ichi, valve yowunikira iyenera kuikidwa pamalo pomwe kusokonezeka kwapakati kumakhala kochepa.
