Mavavu ndi zinthu zomwe zimakhala ndi phindu lochepa, ndipo mpikisano wamsika ndi woopsa kwambiri.Pankhani ya kugawidwa kwa msika wa ma valve, makamaka zimatengera ntchito yomanga zomangamanga.Ogwiritsa ntchito kwambiri ma valve ndi mafakitale a petrochemical, gawo lamagetsi, gawo lazitsulo, makampani opanga mankhwala ndi gawo la zomangamanga zamatawuni.Makampani a petrochemical makamaka amagwiritsa ntchito ma valve okhazikika a API, ma valve a globe ndi ma check valves;gawo lamagetsi makamaka limagwiritsa ntchito ma valve othamanga kwambiri, ma valve padziko lonse lapansi, ma valavu owunika ndi ma valve otetezera magetsi pamalo opangira magetsi ndi ma valve agulugufe otsika kwambiri ndi mavavu a pachipata popereka madzi ndi mavavu otayira;makampani opanga mankhwala makamaka amagwiritsa Stainless zitsulo pachipata mavavu, mavavu globe, mavavu cheke;makampani metallurgical makamaka ntchito otsika-anzanu lalikulu m'mimba mwake agulugufe mavavu, mpweya kutseka mavavu ndi mpweya mavavu mpira;madipatimenti omanga m'matauni makamaka amagwiritsa ntchito mavavu otsika, monga mapaipi amadzi apampopi am'tawuni makamaka amagwiritsa ntchito mavavu am'mimba mwake, ndipo zomangamanga zimagwiritsa ntchito mizere yapakatikati Kwa mavavu agulugufe, mavavu agulugufe osindikizidwa zitsulo amagwiritsidwa ntchito makamaka pakuwotcha kwamatawuni;mavavu lathyathyathya zipata ndi mavavu mpira zimagwiritsa ntchito mapaipi mafuta;zitsulo zosapanga dzimbiri mpira mavavu zimagwiritsa ntchito makampani mankhwala;zitsulo zosapanga dzimbiri mavavu mpira zimagwiritsa ntchito makampani chakudya.Mavavu amagwiritsidwa ntchito kwambiri m'makampani ochizira madzi, makamaka ma valve otsika kwambiri, monga mavavu agulugufe, mavavu a pachipata, ndi ma cheke.Zikumveka kuti pakali pano pali makampani oposa 2,000 a valve omwe ali ndi mlingo wina pamsika, ambiri omwe ali ku Jiangsu, Zhejiang ndi Central Plains.Chifukwa cha zofunikira zochepa zomwe zili ndi luso lazopangapanga, mpikisano umakhala wovuta kwambiri.

Kuyambira m'ma 1980, dziko langa linayamba kukonza mabizinesi ofunikira kuti adziwe luso lazopangapanga ndi zida zopangira zinthu monga mapangidwe ndi ukadaulo wazinthu zofanana kuchokera kumayiko ena, kotero kuti ukadaulo wopanga mavavu adziko langa ndi mtundu wazinthu zasinthidwa mwachangu, ndipo wafika mlingo wa mayiko akunja mu 1980s.Pakalipano, opanga ma valve ofunikira apakhomo atha kupanga ndi kupanga ma valve osiyanasiyana motsatira miyezo yapadziko lonse monga ISO international standards, DIN German standards, AWWA American standards, ndi mankhwala opanga ena afika pamtunda wapadziko lonse lapansi.Ngakhale kuti gawo lonse la mafakitale a valve mu Chaka Chatsopano lakhala likuyenda bwino kwambiri, khalidweli silili lokhazikika mokwanira, monga kuthamanga, kuthamanga, kuthamanga, kuthamanga, ndi kutuluka nthawi zambiri kumawoneka m'ma valve apakhomo.Kuphatikiza apo, pali kusiyana kwina pakati pa mphamvu zothandizira ma valve a dziko langa ndi mayiko otukuka.

Kumbali imodzi, zida za ma valve za dziko langa zikukumana ndi mwayi wotukuka.Ndi kusamutsidwa kwa chitukuko cha mafuta kupita ku minda yamafuta akumtunda ndi minda yamafuta akunyanja, komanso kukula kwamakampani opanga magetsi kuchokera kumagetsi otenthetsera pansi pa 300,000 kilowatts kupita kumagetsi otentha, mphamvu yamadzi ndi mphamvu ya nyukiliya kuposa ma kilowatts 300,000, zida za valve ziyeneranso kusintha magwiridwe antchito awo ndikusintha kofananira. m'munda wa zida ntchito.parameter.Makina omanga m'mizinda nthawi zambiri amagwiritsa ntchito mavavu otsika kwambiri, ndipo akupita patsogolo poteteza chilengedwe komanso kupulumutsa mphamvu, ndiko kuti, kusintha kuchokera ku mavavu achitsulo otsika kwambiri omwe amagwiritsidwa ntchito m'mbuyomu kupita ku mavavu a mbale a rabara ochezeka ndi chilengedwe. mavavu, zitsulo zosindikizira gulugufe mavavu, ndi centerline seal agulugufe mavavu.Kupititsa patsogolo ntchito zoyendera mafuta ndi gasi motsogozedwa ndi mapaipi kumafuna kuchuluka kwa mavavu a zipata ndi ma valve a mpira.Mbali ina yachitukuko cha mphamvu ndikusunga mphamvu, chifukwa chake, potengera kusungitsa mphamvu, misampha ya nthunzi iyenera kupangidwa ndikupangidwa kuti ikhale yocheperako komanso yapamwamba kwambiri.

Ntchito yomanga malo opangira magetsi ikupita patsogolo pakukula kwakukulu, kotero kuti ma valve akuluakulu otetezera chitetezo ndi ma valve ochepetsera mphamvu amafunikira, ndipo ma valve otsegula ndi kutseka amafunikiranso.Pazosowa zamapulojekiti athunthu, kuperekedwa kwa ma valve kwapangidwa kuchokera kumitundu yosiyanasiyana kupita kumitundu yambiri ndi mafotokozedwe.Pali chizoloŵezi chowonjezereka chakuti ma valve omwe amafunidwa ndi ntchito yaumisiri amaperekedwa ndi wopanga ma valve.

Koma kumbali ina, tiyenera kutenga zovuta zambiri pamsika wa valve mozama.Monga msika wa valavu wakudziko langa wapanga mgwirizano wamakampani aboma, gulu, mabizinesi, masheya ndi makampani apadera.Pampikisano woopsa wa msika, womwe umafunikira chitukuko chokhazikika, makampani akuyang'anitsitsa zinthu zotsatirazi: kugwira ntchito mwakhama kuti achepetse ndalama zopangira, kuyang'ana pa kupititsa patsogolo ntchito zamalonda ndi ntchito;kupanga zinthu zamakono zamakono kapena kupanga timagulu tating'ono tating'ono tating'ono tating'ono;kudutsa International khalidwe chitsimikizo cha mankhwala vavu;Zopangira ma valve ziyenera kukula motsata chitetezo cha chilengedwe komanso kupulumutsa mphamvu.Komabe, n'zosapeŵeka kuti opanga ena osakhulupirika omwe amafunafuna phindu monga cholinga chawo ndipo samazengereza kuvulaza zofuna za ena akusokoneza chitukuko cha msika wa valve.
