Valve ya dzikostandardization technical committee msonkhano wowunikiranso womwe unachitikira ku Zhejiang Cixi zokongoletsera mwangozi kugunda chitoliro chakale cha valve kuti athetse vutoli.
Pa Seputembala 26, msonkhano wapadziko lonse wa Valve Standardization Technical Committee unachitikira ku Cixi, Ningbo, m'chigawo cha Zhejiang. Msonkhanowo udawunikiranso ma valve a GB/T84642008 chitsulo ndi ulusi wamkuwa wolumikizana ndi ulusi ndi miyezo inayi ya dziko (Chingerezi Baibulo), ndikuwunikanso template yokonzekera ya miyezo yamankhwala a valve. Kuwunikiridwa kwa muyezo, kusintha ndi kukweza kwa makampani a valve ku China kuti atsogolere ndikugwira nawo ntchito.
Mavavu amagwiritsidwa ntchito kwambiri, kuphatikiza magawo osiyanasiyana monga chitetezo cha dziko, zomangamanga, mafakitale ndi ulimi, komanso kugwiritsa ntchito kunyumba ndi anthu wamba. Ma valve amagwiritsidwa ntchito m'malo onse omwe gasi amagwiritsidwa ntchito. Chifukwa cha izi, mankhwalawa amagawidwa padziko lonse lapansi kukhala kampu yapadera ya zida. Kwa zaka zambiri, China pang'onopang'ono wakhala lalikulu kwambiri padziko lonse processing chomera, chiwerengero cha China mavavu mabizinesi ndi khola mu dziko.
Zaka makumi angapo zapitazo, pamene luso la mafakitale linali lobwerera m'mbuyo, dziko la China linkadalira kuitanitsa kunja kwa ma valve otetezera ndi zinthu zina, ndipo ngakhale miyezo ya dziko lonse inali yochokera ku mayiko akunja. Mpaka 2007, moyang'aniridwa ndi zofunikira za National Development and Reform Commission, Zhejiang Chaochao Company ndi Hefei General Machinery Research Institute adalemba bwino za "Safety Valve for Compressor" JB/T 64412008. kukonza ndi kupanga zinthu za valve kudzayang'anizana ndi malo okulirapo a chitukuko. Vavu ngati chinthu chapadera, makampani ofunikira, zofunikira zamtundu ndizofunikira kwambiri. Kuwunikiridwa kwa miyezo inayi yamayiko amakampani opanga ma valve pamsonkhanowu kudzasinthanso ndikukweza makampani.
Mzinda wa Cixi nthawi zonse umakhala wofunikira pakuwongolera mabizinesi kuti atenge njira yachitukuko yamakampani okhazikika. Cixi City m'zaka zaposachedwa, kukhazikitsidwa kwa njira yokhazikika ngati chinthu chofunikira kwambiri, kulimbikitsa kusintha kwachuma ndi kukweza kwa chitukuko chokhazikika chautumiki, kukhala zatsopano monga mphamvu, * * * * boot, kutenga nawo mbali pagulu, kumanga bizinesi ngati gulu lalikulu la njira yokhazikika yogwirira ntchito, kuwongolera bwino komanso kuchuluka kwa zinthu, kulimbikitsa malonda ndi luso laukadaulo, kusintha mphamvu ndi kukweza kwa cixi. Mpaka pano, mabizinesi okwana 68 adatsogolera kukonzanso kwa 164 padziko lonse lapansi, mayiko ndi mafakitale, omwe adatsogolera pakukhazikitsa miyezo yadziko ndi mafakitale 74, chiwerengero chonse cha zigawo za Ningbo ndi madera akumatauni, mabizinesi awiri adatenga nawo gawo. pakupanga zoyatsira ndi ma hood osiyanasiyana pamiyezo yapadziko lonse lapansi, ndikupanga chitsanzo pamakampani apakhomo.
Kukongoletsa mwangozi kugunda chitoliro chakale mbuye valavu kuthetsa vuto ananena kuti pamene kukongoletsa madzi ndi magetsi ndi ** akhoza kupereka vuto, ** kumayambiriro kwa kalata yanga, mosayembekezereka chokongoletsera shawa yanga, chifukwa sanali chizindikiro payipi. pasadakhale, mwachindunji kugunda mng'alu chitoliro! Mbuye amene amakongoletsa kunyumba kwanga akuti, ngati asintha mawu, agwetse metope, muzu wonse umasintha kuthekera kopita, zovuta kwambiri. ***, mbuye wakale adayang'ana kumbuyo, adayika valve kuti athane ndi vutoli.
Onse ananena kuti pamene ulemerero wa madzi ndi magetsi ndi ** kungakhale vuto, ** kumayambiriro kwa kalata yanga, koma shawa kukongoletsa wanga, chifukwa palibe oyambirira chizindikiro chitoliro udindo, mwachindunji losweka chitoliro madzi! Mbuye amene amakongoletsa kunyumba kwanga akuti, ngati asintha mawu, agwetse metope, muzu wonse umasintha kuthekera kopita, zovuta kwambiri. ***, mbuye wakale adayang'ana kumbuyo, adayika valve kuti athane ndi vutoli.
wantchitoyo akuti ndi ine, perforation ayenera anagundidwa pasadakhale pamaso zokongoletsa, dikirani kukongoletsa mwinamwake m'tsogolo, akhoza kuoneka kugunda mng'alu ceramic matailosi kapena kugunda nkhani kuti ming'alu ngalande, lonse ngati kusintha chubu, ndi vuto kwambiri. Ndi bwino kuyang'ana valavu kuti alibe lophimba, kudula payipi kuti kudula ndi kugawanika pa malekezero onse odulidwa lotseguka, m'malo mawonekedwe ndi valavu, kusindikiza ndi madzi matope kachiwiri lotsatira, sitolo latsopano timitengo ceramic matailosi kupita.
Anthu ambiri amawopa kuti valavu ya mawonekedwe awa ichita dzimbiri, ndipo si vuto kugwiritsa ntchito simenti m'tsogolomu, ndi zaka khumi ndi ziwiri kapena makumi awiri. Ngati mukuda nkhawa, mutha kugula mwachindunji mawonekedwe a PPR. Komabe, kusowa kwa kukonza kumeneku ndikuti gawo la mawonekedwe ndi lopapatiza kwambiri, zomwe zingakhudze kuthamanga kwa madzi.
Pali Njira yokonzanso yodziwika bwino ndikugwiritsa ntchito dothi lachitsulo lapulasitiki, ndi abale abwino ofanana, A, B mbali ziwiri. Pokonza mapaipi amadzi ndi dothi lapulasitiki, ndikofunikira kutseka ma valve onse kuti muwonetsetse kuti palibe kuthamanga kwa madzi. Kenaka pakani mbali zonse ziwiri mofanana ndi madzi ofunda, kumbukirani kuti muyenera kuviika ndi madzi ofunda ndikulimbitsa pang'onopang'ono, mwinamwake sichidzamamatira.
Ndiye wokutidwa ndi yopyapyala, monga maola 24 pambuyo madzi kuona ngati pali vuto kutayikira. Ngati kutayikira, konzaninso, mpaka musatayike, mutha kupukuta simenti, kumamatira matailosi a ceramic mwatsopano, wamba mtundu uwu wa nthaka yachitsulo sichidzawoneka ngati vuto mkati mwa zaka 10. Ngati mukufuna kulimbitsa mofulumira, mungagwiritse ntchito chowumitsira tsitsi pamzere.
