Zofunikira pakuyika valavu yamagetsi pazabwino zamapangidwe ndi luso laukadaulo

Vavu ndi mu dongosolo madzimadzi, ntchito kulamulira malangizo a madzimadzi, kuthamanga, otaya chipangizo, ndi kupanga chitoliro ndi zipangizo sing'anga (zamadzimadzi, mpweya, ufa) kuyenda kapena kuima ndipo akhoza kulamulira otaya chipangizo. Valve ndi gawo lowongolera la kayendedwe ka mapaipi amadzimadzi, omwe amagwiritsidwa ntchito kusintha gawo la njira ndi njira yolowera pakati, ndi kuphatikizika, kudula, kugunda, cheke, shunt kapena mpumulo wa kusefukira kwamphamvu ndi ntchito zina. Mavavu owongolera madzimadzi amachokera ku mavavu osavuta a globe kupita ku omwe amagwiritsidwa ntchito m'makina ovuta kwambiri owongolera okha, okhala ndi mitundu yosiyanasiyana komanso mawonekedwe, kuyambira makulidwe odziwika kuchokera ku ma valve a zida zazing'ono kwambiri kupita ku ma payipi a mapaipi a mafakitale mpaka 10m. Angagwiritsidwe ntchito kulamulira otaya madzi, nthunzi, mafuta, gasi, matope, mitundu yonse ya TV zikuwononga, madzi zitsulo ndi radioactive madzimadzi ndi mitundu ina ya madzimadzi, valavu ntchito kuthamanga kungakhale kuchokera 0.0013mpa kuti 1000MPa mkulu kuthamanga, ntchito kutentha C-270 ℃ mpaka 1430 ℃ kutentha kwambiri. Kuwongolera mavavu kungagwiritse ntchito njira zosiyanasiyana zotumizira, monga manual, magetsi, hydraulic, pneumatic, turbine, electromagnetic, electromagnetic hydraulic, hydraulic hydraulic, pneumatic, spur gear, bevel gear drive, etc.; Pakukakamiza, kutentha kapena mawonekedwe ena pansi pa ma sensa a sensa, kuchitapo kanthu, malinga ndi kufunikira kwa kusungitsa kapena kusadalira ma sensor a sensor kuti atsegule kapena kutseka, kudalira pagalimoto kapena makina odziwikiratu amapanga valavu yotsegula ndi kutseka. kukweza, kutsetsereka, malo kapena kusuntha kozungulira, kuti musinthe kukula kwa doko kuti muzindikire ntchito yolamulira. Zofunikira pakuyika 1, musanayambe kuyika ma valve, muyenera kuyang'ana mosamala mtundu wa valve, mawonekedwe ndi kapangidwe; 2, malinga ndi chitsanzo cha valve ndi malangizo a fakitale kuti muwone ngati valavu ingagwiritsidwe ntchito pazochitika zofunika; 3. Pokweza valavu, chingwecho chiyenera kumangirizidwa ku mgwirizano wa flange wa thupi la valve ndi chivundikiro cha valve, osati kumangirizidwa ku handwheel kapena tsinde, kuti musawononge tsinde ndi handwheel; 4. Pamene valavu imayikidwa pa payipi yopingasa, tsinde la valve liyenera kukhala lokwera pamwamba, ndipo sililoledwa kuyikidwa pansi; 5, pakukhazikitsa valavu, musagwiritse ntchito njira yolumikizirana mokakamiza, kuti musawononge chifukwa cha mphamvu yosagwirizana; 6, valavu yachipata cha tsinde sayenera kuyikidwa pamalo onyowa pansi pa nthaka, kuti asawononge dzimbiri. Assembly zofunika mbali woyera ayenera losindikizidwa unsembe. Zofunikira pakuyikapo ndi izi: 1. Malo ochitirako unsembe ayenera kukhala aukhondo, kapena kukhazikitsa malo aukhondo kwakanthawi, monga nsalu zamitundu yongogulidwa kumene kapena filimu yapulasitiki, kuti fumbi lisalowe panthawi yoyika. 2, ogwira ntchito pamsonkhano ayenera kuvala zovala zoyera za thonje, kuvala chipewa choyera cha thonje, tsitsi silingatuluke, mapazi amavala nsapato zoyera, manja amavala magolovesi apulasitiki, amachotsa mafuta. 3, zida msonkhano ayenera degreased pamaso msonkhano, kuonetsetsa woyera. Zofunikira Zovomerezeka Kuvomerezedwa kuli molingana ndi HG 20202-2000 Code for Construction and Acceptance of Degreasing Engineering. Musanasonkhane, pukutani gawo lililonse ndi pepala loyera bwino, sankhani ngodya zakufa za magawo, ndipo pepala losefera lokhala ndi mtundu wosasinthika ndiloyenera. 1, mtundu wa valve uyenera kuwonetsedwa molingana ndi zofunikira za nambala ya NATIONAL. Ngati mulingo wabizinesi, uyenera kuwonetsa kufotokozera koyenera kwachitsanzo. 2, valavu yogwira ntchito, zofunikira ≥ payipi yogwira ntchito, popanda kukhudza mtengo wa malo, valavu imatha kupirira kupanikizika kuyenera kukhala kwakukulu kuposa kuthamanga kwenikweni kwa payipi. 3, miyezo yopanga ma valve, iyenera kufotokozera maziko a nambala ya NATIONAL, ngati muyezo wabizinesi, mgwirizano wogula uyenera kumangirizidwa ku chikalata chamakampani. Kuti mumve zambiri, chonde onani: Zofunikira pakuyika kwa valavu Yamapangidwe Ubwino ndi ukadaulo wa valavu yamagetsi "Power station valve", yomwe imadziwikanso kuti valavu yamagetsi, imagwira ntchito makamaka pamapaipi amagetsi osiyanasiyana amagetsi otenthetsera, kudula. kapena kulumikiza media media. Sing'anga yogwiritsidwa ntchito: madzi, nthunzi ndi sing'anga ina yosawononga. Poyerekeza ndi zinthu zina za valve, valavu yamagetsi imadziwika ndi kutentha kwakukulu ndi kupanikizika kwakukulu, mapangidwe apadera odzisindikiza, kuthamanga kwapamwamba, kusindikiza kodalirika kwambiri. Chifukwa cha magwiridwe antchito apadera, mawonekedwe aukadaulo ndi magwiridwe antchito, mankhwalawa apanga mawonekedwe omwe zinthu zina sizingasinthidwe. Mpando wa valve ndi kusindikiza kwa disc kumapangidwa ndi kuwotcherera kwa cobalt-based carbide plasma spray, ndi kukana bwino kwa abrasion komanso kukana abrasion.
I. Chidule cha valavu yamagetsi
"Vavu yamagetsi" imadziwikanso kuti valavu yamagetsi, makamaka yoyenera malo opangira magetsi pamapaipi osiyanasiyana, odulidwa kapena kupyola papaipi. Sing'anga yogwiritsidwa ntchito: madzi, nthunzi ndi sing'anga ina yosawononga. Poyerekeza ndi mankhwala ena a valve, valavu yamagetsi imadziwika ndi kutentha kwakukulu ndi kupanikizika kwakukulu, mapangidwe apadera odzisindikiza, kuthamanga kwapamwamba, kusindikiza kodalirika kwambiri. Chifukwa cha magwiridwe antchito apadera, mawonekedwe aukadaulo ndi magwiridwe antchito, mankhwalawa apanga mawonekedwe omwe zinthu zina sizingasinthidwe.
