Kodi mukuvutika kusankha valavu yoyenera ya polojekiti yanu? Kodi mukuvutitsidwa ndi mitundu yosiyanasiyana ya ma valve ndi mitundu pamsika? Mumitundu yonse yama projekiti aukadaulo, kusankha valavu yoyenera ndikofunikira kwambiri. Koma msika uli wodzaza ndi ma valve. Chifukwa chake taphatikiza chitsogozo chokuthandizani mosavuta komanso mwanzerusankhani chinthu choyenera cha valve kwa inu. Kaya mukufunika kuwongolera kuthamanga, kuwongolera kuthamanga kapena kutsika kwamadzimadzi, tili ndi malangizo ndi zidule za inu. Chitanipo kanthu molimba mtima kudzera munjira ya valve iyi ndipo sangalalani ndi mtengo komanso kupulumutsa nthawi mukugwira ntchito yomanga bwino.

1.Kudziwa cholinga cha valve mu zipangizo kapena chipangizo

Dziwani momwe ma valve amagwirira ntchito: chikhalidwe cha sing'anga yoyenera, kuthamanga kwa ntchito, kutentha kwa ntchito ndi kulamulira.

2.Sankhani mtundu wolondola wa valve

Kusankha koyenera kwa mtundu wa valavu kumatengera momwe wopanga amagwirira ntchito yonse yopangira ndi momwe amagwirira ntchito monga chofunikira, posankha mtundu wa valavu, wopangayo ayenera kudziwa kaye mawonekedwe ndi magwiridwe antchito a valve iliyonse.

3.Tsimikizirani kugwirizana kwa mapeto a valve

Polumikizana ndi ulusi, malumikizidwe a flange, ndi ma welded end kulumikizana, awiri oyambawa amagwiritsidwa ntchito kwambiri. Ma valve opangidwa ndi ulusi makamaka ma valve okhala ndi m'mimba mwake pansi pa 50mm, ngati kukula kwake kuli kwakukulu, kuyika ndi kusindikiza gawo logwirizanitsa ndilovuta kwambiri. Valavu yolumikizidwa ndi Flange, kuyika kwake ndi kuphatikizika kwake ndikosavuta, koma valavu yolumikizidwa ndi ulusi imakhala yokulirapo, mtengo wake ndi wokwera, chifukwa chake ndiyoyenera kusiyanasiyana kosiyanasiyana ndi kukakamiza kwa mayendedwe a payipi. The welded kugwirizana ndi oyenera zinthu apamwamba katundu kudula ndi odalirika kuposa kugwirizana flange. Komabe, disassembly ndi reinstallation wa mavavu welded ndi zovuta kwambiri, choncho ntchito yake ndi malire nthawi imene nthawi zambiri ntchito modalirika kwa nthawi yaitali, kapena kumene mikhalidwe ntchito ndi zolemba ndi kutentha ndi apamwamba.

4.Valve kusankha zinthu

Kusankhidwa kwa chipolopolo cha valve, ziwalo zamkati ndi kusindikiza pamwamba pa zinthu, kuwonjezera pa kulingalira zakuthupi za sing'anga yogwira ntchito (kutentha, kuthamanga) ndi katundu wa mankhwala (kudzimbirira), ayeneranso kudziwa ukhondo wa sing'anga (palibe tinthu tating'onoting'ono tolimba). ), kuwonjezera, komanso kutchula zofunikira za boma ndi kugwiritsa ntchito dipatimentiyo. Kusankhidwa koyenera komanso koyenera kwa zida za valve kumatha kupeza moyo wabwino kwambiri wautumiki komanso magwiridwe antchito abwino kwambiri a valve. Kusankhidwa kwa zida zamagulu a valve ndi: chitsulo choponyedwa - chitsulo cha carbon - chitsulo chosapanga dzimbiri, ndi mndandanda wosankhidwa wa zipangizo zosindikizira mphete ndi: rabara - mkuwa - alloy steel -F4.

5.izi

Kuonjezera apo, kuthamanga kwa kuthamanga ndi kuthamanga kwa madzi omwe akuyenda mu valve ayenera kutsimikiziridwa, ndipo valavu yoyenera iyenera kusankhidwa pogwiritsa ntchito zomwe zilipo (monga kabuku ka mankhwala a valve, zitsanzo za mankhwala a valve, etc.). 

 JinbinValvendi wopanga odzipereka kupereka mavavu apamwamba kwambiri, ndipo zogulitsa zake zimatumizidwa kumayiko ambiri ku Southeast Asia ndi America. Lumikizanani nafe tsopano ndipo tiloleni tisinthe njira yabwino kwambiri ya valve kwa inu!
