Valavu yowunikira ya bonnet yotsekedwa bwino kwambiri yamakampani opanga mafakitale ku China
Kodi valavu yoyezera boniti yotsekedwa ndi mphamvu ndi chiyani?
Ma valve owunikira, ma valve osabwezera, apangidwa kuti aletse kutembenuka kwa kayendedwe ka madzi mu dongosolo la mapaipi. Ma valve awa amayatsidwa ndi zinthu zomwe zimayenda mupaipi.Kupanikizika kwa madzi omwe amadutsa mu dongosolo kumatsegula valavu, pomwe kutembenuka kulikonse kwa kayendedwe ka madzi kudzatseka valavu.Kutseka kumachitika ndi kulemera kwa makina owunikira, ndi kupanikizika kwa msana, ndi kasupe, kapena kuphatikiza njira izi.
valavu yowunikira boniti yosindikizidwa, valavu yowunikira swing yopangidwa ndi kupangidwa molingana ndi ASME B16.34, yesani ndikuyang'ana API598, API6D.
Mpata umenewo uyenera kukhala wowonekera bwino kuti chilichonse chidutse. Disikiyo imalumikizidwa ku hinge, kotero disikiyo imatha kutseguka kapena kutsekedwa madzi akagunda diskiyo. Ili ngati chitseko chozungulira. Kulowera kwa madzi ndiye chinthu chofunikira kwambiri mukamagwiritsa ntchito ma valve awa.
Monga tanenera kale, valavu yowunikira swing ndi yoyenera ngati mukufuna madzi kuyenda mbali imodzi yokha. Chinthu china chofunikira chokhudza mavalavu awa ndichakuti safuna mphamvu yakunja, zomwe zimapangitsa kuti akhale abwino kwambiri pa ntchito zosiyanasiyana. Amalolanso madzi kudutsa popanda kuchepetsa kuthamanga kwa madzi nthawi zambiri akatsegulidwa kwathunthu.Ma valve oyesera ozungulira nthawi zambiri amaikidwa pamodzi ndi ma valve a chipata chifukwa amapereka madzi oyenda bwino.Amalimbikitsidwa pa mizere yomwe imayenda mofulumira kwambiri ndipo sayenera kugwiritsidwa ntchito pa mizere yomwe imayenda mofulumira kwambiri pamene kugwedezeka kosalekeza kapena kugwedezeka kungawononge mipando.Vutoli likhoza kukonzedwa pang'ono pogwiritsa ntchito chowongolera chakunja ndi kulemera.
Zinthu zazikulu za valavu yoyang'anira bonnet yotsekedwa ndi kupanikizika
Zinthu Zazikulu zavalavu yowunikira boniti yosindikizidwa:
- ● Thupi ndi chivundikiro: Ma castings opangidwa mwaluso. Tsinde sililowa m'thupi.
- ● Disiki: Yopangidwa ndi chidutswa chimodzi cholimba kuti ipirire kugwedezeka kwakukulu kwa ntchito yowunikira ma valve. Yolimba yokhala ndi 13Cr, aloyi ya CoCr, SS 316, kapena Monel, yaphwanyidwa ndikulumikizidwa mpaka kumapeto kwa galasi. Disiki ya SS 316 yokhala ndi aloyi ya CoCr ikupezekanso.
- ● Kumanga ma disc: Ma disc osazungulira amamangiriridwa bwino ku chitseko cha ma disc ndi nati yotsekera ndi pini ya cotter. Chitseko cha ma disc chimathandizidwa ndi pini yolimba yonyamulira ma disc yokhala ndi makhalidwe abwino kwambiri. Zigawo zonse zimapezeka kuchokera pamwamba kuti zikhale zosavuta kuzisamalira.
