Opanga ma valavu amakhulupirira kuti ma valavu wamba amatseka mwachangu ndipo amakonda nyundo yamadzi, zomwe zimapangitsa kuti pakhale kuthamanga kwadzidzidzi, kuwonongeka kwa mapaipi ndi zida, komanso phokoso lalikulu.Valavu yotsekera pang'onopang'ono imathetsa mavuto omwe amayamba chifukwa cha kutseka kofulumira kwa ma valve wamba.Amagwiritsidwa ntchito mwachindunji madzi ndi ngalande machitidwe a mafakitale ndi migodi mabizinezi ndi mkulu nyamuka nyumba, akhoza kuchepetsa zimachitika nyundo madzi ndi nyundo madzi ndi kukwaniritsa zotsatira za shutdown otetezeka.
1. Mapangidwe a valavu yotsekera pang'onopang'ono ya micro-resistance:
Valavu imodzi imayikidwa kutsogolo kwa valve, ndipo valavu imodzi imayikidwa kumbuyo kwa valve, yomwe ndi yabwino kukonza.Ikani fyuluta kutsogolo kwa valve kuti muteteze zonyansa mu dongosolo la mapaipi kuti zisalowe mu valve.Opanga ma valve amayang'ana amakhulupirira kuti valavu yotsekera pang'onopang'ono iyenera kuyikidwa mozungulira.Ngati valavu yaikidwa m'chitsime, payenera kukhala malo okonzekera.Valavu yotulutsa yokhayokha iyenera kuyikidwa papaipi molingana ndi zofunikira kuti zitsimikizire kuyenda kosalekeza kwa mzere wamadzi.
2. Mfundo yogwirira ntchito ya valavu yotsekera pang'onopang'ono yoletsa kukana:
Pampu yamadzi ikayambika: wopanga ma valve a cheke amakhulupirira kuti kukakamiza kwa valavu kumapangitsa kuti valavu ya valve itseguke mwachangu motsutsana ndi mphamvu ya masika, ndipo sing'anga panjira yayikulu ya valve imalowa m'chipinda chapamwamba cha diaphragm kudzera mu valavu ya singano. ndi valve check.Sinthani kutsegulira kwa vavu ya singano, kuti sing'anga yomwe imalowa m'chipinda chapamwamba cha diaphragm igwire ntchito pa mbale yothamanga ya diaphragm, ndipo mphamvu yowonjezera imapangidwa pa diski ya valve kuti iwonetsetse kuti valavu ya valve imatsegulidwa pang'onopang'ono.Sinthani kutsegulira kwa valavu ya singano polowera kwa valavu yayikulu, kuwongolera kuthamanga kwa valve, ndikuwonetsetsa kuti nthawi yotsegulira valavu yayikulu ndi yayitali kuposa nthawi yoyambira pampu, kuti pampu iyambe. pansi pa katundu wopepuka ndikuletsa injini yoyambira pano kuti ikhale yayikulu kwambiri.
Pamene pampu yamadzi imazimitsidwa: wopanga ma valve a cheke amakhulupirira kuti kupanikizika kwa valve kumalowa kumachepa mwadzidzidzi, ndipo phokoso la valve lidzatseka mwadzidzidzi pansi pa kukanikiza pamtunda, zomwe zimapangitsa kuti pakhale kuwonjezereka kwadzidzidzi pazitsulo za valve.Panthawiyi, nyundo yamadzi ndiyosavuta kuchitika, kuwononga payipi ndi zida kumbuyo kwa valve, ndikupanga phokoso lalikulu.
Wopanga valavu yoyang'ana amakhulupirira kuti chifukwa njira yobwerera imayikidwa kumapeto kwa valve, sing'anga pambuyo poti valavu ilowa m'chipinda chapamwamba cha diaphragm kupyolera mu valve ya mpira.Chifukwa cha cheke cha cheki cha valve, sing'anga siyingalowe kumapeto, ndipo chipinda chapansi cha diaphragm chimadzazidwanso ndi sing'anga.Ngakhale kupanikizika kwa sing'anga m'chipinda cham'mwamba kumalimbikitsa kutseka kwa valavu, sing'anga yomwe ili m'chipinda chapansi sichingatulutsidwe mwamsanga pansi pa kabowo kakang'ono ka mpando wa diaphragm, zomwe zimapangitsa kuti pakhale kutsekedwa, zomwe zimalepheretsa kutseka liwiro la valavu chotchinga ndi kukwaniritsa kutseka pang'onopang'ono.The osalankhula kwenikweni amalepheretsa madzi nyundo chodabwitsa.Mwa kusintha kutsegula kwa valve ya mpira, kuthamanga kwa valve disc (ie nthawi yotseka ya valve) ikhoza kuyendetsedwa bwino.
Wopanga valavu ya cheke amakhulupirira kuti valavu yotsekera pang'onopang'ono ili ndi mawonekedwe aukadaulo otsegula pang'onopang'ono ndikutseka pang'onopang'ono ndikuchotsa nyundo yamadzi, yomwe imazindikira kuyambika kwapampu ndikuletsa kuchitika kwa nyundo yamadzi pomwe mpope. ayimitsidwa.Pambuyo poyambitsa injini yapampu, valavu imatsegula ndi kutseka molingana ndi pulogalamu yogwiritsira ntchito mpope.Valovu yoyang'ana imatanthawuza valavu yomwe imatsegula ndi kutseka chitseko cha valve ndi kutuluka kwa sing'angayo kuti iteteze kubwerera kumbuyo kwa sing'anga.
Opanga ma valve amayang'ana amakhulupirira kuti valavu yoyang'anira ndi valavu yodziwikiratu, ndipo ntchito yake yayikulu ndikuletsa kubweza kwa sing'anga, kuteteza kusinthasintha kwa mpope ndi galimoto yoyendetsa, ndikumasula sing'anga mu chidebecho.Ma valve owunika atha kugwiritsidwanso ntchito popanga mapaipi opereka makina othandizira pomwe kupanikizika kumatha kukwera pamwamba pa kukakamiza kwadongosolo.Ma valve owunikira amatha kugawidwa kukhala ma valve oyendera (ozungulira molingana ndi pakati pa mphamvu yokoka) ndikukweza ma valve (akuyenda mozungulira).
