Valavu isanaikidwe, kuyesedwa kwamphamvu kwamphamvu ndi mayeso a Valave kuyenera kuchitika pa benchi. 20% ya mavuvu otsika othamanga ayenera kuyang'aniridwa mwachisawawa, ndipo 100% amayenera kuzolowera ngati alibe chochita; 100% ya ma valves apakatikati ndi akulu kwambiri amayenera kuwunikidwa. Makina ogwiritsira ntchito makanema omwe amagwiritsidwa ntchito ndi madzi, mafuta, mpweya, nthunzi, nayitrogeni, ndi zina zambiri zoyeserera za mavuni a mafakitale ndizotsatira:
Gulugufe wagunda
Kuyesa mphamvu kwa valavu ya chibayo ndi chinthu chomwe cha Globeb. Poyeserera kusindikizidwa kwa valavu ya gulugufe, sing'anga yoyeserera iyenera kutsegulidwa kuchokera kumapeto kwa sing'anga, Mapazi a gulugufe iyenera kutsegulidwa, kumapeto kwake kuyenera kutsekedwa, ndipo kupsinjika jakisoni kuyenera kufika mtengo; Pambuyo poyang'ana kuti palibe kutaya pa kunyamula ndi zisindikizo zina, kutseka mbalegule, tsegulani mbali inayo, ndikuyang'ana valavu ya gulugufe. PALIBE MALO OGULITSIRA MALO OGULITSIRA. Vewi la Gulugufe lomwe limagwiritsidwa ntchito pokonzanso zotuluka sizingayesedwe popewa.
Njira yoyesera yoyeserera
Chongani mayeso a Valuve: Axis ya kukweza valve disc ili pamalo opondera kuloza; The axis ya Swing Check Valve Checkve ndi ma axis axis ali pamalo pafupifupi pafupifupi mzere wopingasa.
Panthawi yoyesa, sing'anga ya mayeso imayambitsidwa kuchokera pamtengo wotsimikizika, ndipo mathero enawo amatsekedwa, ndipo ndi woyenera kuwona kuti thupi la valavu ndi Valve sizimataya.
Poyeserera kosindikizira, sing'anga ya mayeso imayambitsidwa kuchokera pa malo ogulitsira, ndipo malo osindikizira amafufuzidwa kumapeto, ndipo palibe kutaya pa kunyamula ndi gasket ndikoyenera.
Njira yoyesera yoyeserera ya pachipata
Kuyesa kwamphamvu kwa valavu yachipata ndi yofanana ndi valavu yapadziko lapansi. Pali njira ziwiri zoyeserera zolimba za valavu ya pachipata.
①Tsegulani chipata kuti musinthe mu valavu ikukwera pamtengo wotchulidwa; Ndiye tsekani chipata, chotsani valavu ya pachipatayo nthawi yomweyo, onani ngati pali dontho la ziwonetsero mbali zonse za chipatacho pachipata chotsimikizika cha chipata. Njira yomwe ili pamwambapa imatchedwa mayeso apakatikati. Njirayi siyenera kugwiritsidwa ntchito poyesa kusindikizidwa pachipata pachipata ndi mainchesi mwanyimbo pansipa DN32mm.
②Njira ina ndikutsegula chipata kuti zitheke kuti zikhale zoyeserera bwino; Kenako tsekani chipata, tsegulani kumapeto kwa mbale yakhungu, ndikuwona ngati malo osindikizira akungotaya. Kenako bwerera ndikubwereza mayeso omwe ali pamwambawa mpaka atayenerera.
Kuyesedwa kwamphamvu kwa kunyamula ndi gasket ya valavu ya pira ya chibayo idzachitika musanayesere chipata.
Njira yoyesera kukakamiza kuchepetsa valavu
①Kuyesa mphamvu kwa kupanikizika kumachepetsa valavu imaphatikizidwa pambuyo poyesedwa kamodzi, ndipo amathanso kuyesedwa pambuyo pa msonkhano. Kutalika kwa kuyesedwa kwamphamvu: 1min ya DN <50mm; Zoposa 2min ku DN65~150mm; oposa 3min a DN> 150mm.
Pambuyo pa minyewa ndi zigawo zomwe zimawombedwa, gwiritsani ntchito 1.5 maulendo 1.
②Mayeso a andirtighy adzachitika molingana ndi sing'anga kwenikweni. Mukamayesa ndi mpweya kapena madzi, yesani pa 1.1 kupsinjika mwadzina; Mukamayesa ndi nthunzi, gwiritsani ntchito zovuta zomwe zimaloledwa kuloledwa. Kusiyana pakati pa kupanikizika kwa itlet ndi kupanikizika kwa dzuwa kumafunikira kuti musakhale ochepera 0,2mpha. Njira yoyeserera ndi iyi: Kukakamizidwa kwa invot kumasinthidwa, kumasinthira pang'onopang'ono kusinthika kwa valavu, kotero kuti kupanikizika kwa extlet kungasinthe mawonekedwe okwanira komanso osasunthika kapena kukwiya. Kwa steam spring ochepetsa valavu, pomwe kupanikizika kwa itrat kumasinthidwa, valavu imatsekedwa ikatsekedwa, ndipo kukakamizidwa kwa extile ndikofunikira kwambiri komanso zochepa kwambiri. Pakati pa 2min, kuwonjezereka pakukopani kwa extilet kuyenera kukwaniritsa zofunikira pagome 4.176-22. Nthawi yomweyo, mapaipi kumbuyo ku Valuve ayenera kukhala vocy imagwirizana ndi zofunikira mu tebulo 4.18 kuti akhale oyenerera; Kwa madzi ndi mpweya kuthamanga kumachepetsa mavuvu, pomwe kupanikizika kwa insut kumakhazikitsidwa ndipo kupanikizika kwa extlet ndi zero, kupanikizika kochepetsa mavesi kumatsekedwa kuti muyesedwe kolimba, ndipo palibe nthawi yokwanira.
Njira yoyeserera yoyeserera kuti ikhale ndi valavu yamakono
Kwa kuyesedwa kwamphamvu kwa Globel Valve ndi valavu yazosonkhanitsidwa nthawi zambiri imayikidwa muyeso woyeserera, sing'angayo imalowetsedwa pamtengo wotsimikizika, ndipo thupi la valavu ndi kuthira. Kuyesedwa kwa mphamvu kumathanso kuchitika pachidutswa chimodzi. Kuyesedwa kwamphamvu kumangokhala ku valavu yotseka. Pa mayeso, valavu yamphamvu ya dziko lapansi ili mu malo ofukula, valavu imatsegulidwa, sing'anga imayambitsidwa kuchokera kumapeto kwa mtengo wake, ndipo kulongedza ndi gasket imayang'aniridwa; Pambuyo podutsa mayeso, valavu imatsekedwa, ndipo mathero enawo amatsegulidwa kuti awone ngati pali kutaya. Ngati mphamvu ndi kuyesedwa kwamphamvu kwa valavu ikuyenera kuchitidwa, kuyesa mphamvu kungachepetse koyamba, ndipo kulongedza ndi gasiketi ndi garket; Kenako disc yatsekedwa imatsekedwa, ndipo mathero ake amatsegulidwa kuti awone ngati malo osindikizira akungotaya.
Njira ya mpira
Kuyesa mphamvu kwa chibayo cha chibayo kuyenera kuchitika pakatikati pa valavu ya mpira.
①Mayeso owonda a mpira osindikizira: Ikani valavu pamalo otseguka theka, imbitsani kuyesa kwa mayeso kumapeto kwake, ndikutseka mbali inayo; Pindani mpira kangapo, tsegulani kumapeto pomwe valavu ili pamalo otsekedwa, ndikuyang'ana momwe masitepe amakhalira ndi masiketi nthawi yomweyo. Pasakhale kutaya. Woyesererayo akuyambitsidwa kuchokera kumapeto kwina ndipo mayeso omwe ali pamwambawa amabwerezedwa.
②Kuyesedwa kwa mpira wokhazikika: Pamaso pa mayeso, kuzungulira mpira kangapo popanda katundu, valavu yokhazikika ili pamalo otsekedwa, ndipo sing'anga wa mayeso amayambitsidwa kuchokera kumapeto kwa mtengo. Kugwirira koyambirira kwa malekezero kumayang'aniridwa ndi zovuta zomwe zimapanikizika, komanso kulondola kwa gauge. Mkati mwa nthawi yodziwika, ngati palibe chonyansa chodabwitsa, ndi oyenera; Kenako ingodziwitsani sing'anga ya mayeso kuchokera kumapeto ena, ndikubwereza mayeso omwe ali pamwambapa. Kenako, ikani valavuyo pakati pa theka lotseguka, tsekani malekezero onse, ndikudzaza mkati mwa mkati ndi sing'anga. Chongani kulongedza ndi garket pansi pa kukakamizidwa, ndipo sipadzakhala kutaya.
③Valavu yanjira zitatu idzayesedwa chifukwa cha malo aliwonse.
