Chofunikira pakuwunika kwa valve control ndi chiyani

Ma valve olamulira ndi gawo lofunika kwambiri pazochitika zina zomwe ma valve olamulira amateteza zipangizo panthawi yowonjezereka.Choncho ntchito yoyenera ya valavu yolamulira imafunika kuti pakhale chitetezo cha zipangizo.Kotero ngati tifunika kuonetsetsa chitetezo cha chipangizocho ndiye kuti valve yolamulira iyenera kuyang'aniridwa.Pali mitundu yosiyanasiyana ya ma valve olamulira monga valavu ya globe, valavu ya mpira, ndi zina zotero, ndipo aliyense wa iwo amagwira ntchito yofunika kwambiri mu ndondomeko kotero ngati ma valve sakugwira ntchito bwino ndiye kuti ndondomekoyi idzasokonezedwa kapena pangakhale kuwonongeka kwa zipangizo zomwe tikufunikira. kuonetsetsa kuti valavu yowongolera ikugwira ntchito bwino.Kuyang'anira mbali za valve yolamulira kuyenera kuchitidwa ndipo ngati pali zolakwika ndiye kuti ziyenera kusamalidwa.

Kuyang'ana pamaso pa unsembe
Valve yolamulira iyenera kuyang'aniridwa musanayike kuti tipeze ngati pali vuto lililonse mu valve yolamulira ndipo ikhoza kukonzedwa.Njira zoyendera valavu musanayike.
• Njira yoyendetsera kayendetsedwe kake iyenera kutsimikiziridwa kuti iwonetsetse kuyika koyenera, ma valve ena sali a bidirectional.Kotero pamene ma valve oyendetsa ma swing aikidwa ndiye kuti njira yothamanga iyenera kuyang'aniridwa
• Yang'anani valavu m'maso ndikuyang'ana chinthu china chilichonse chakunja mu valavu chifukwa chikhoza kuwononga valavu
• Malo a actuator adziwike

Mu kuyendera utumiki
Ma valve oyendetsa amawunikiridwa muutumiki kuti adziwe ngati pali vuto lililonse mu valve panthawi ya ntchito yake komanso kuyang'ana ngati zigawozo zikugwira ntchito bwino pansi pa machitidwe ogwira ntchito.Poyang'anira valavu panthawi yautumiki, tifunika kusintha zinthu zina monga kukonzanso kulongedza kuti valve ikhale yogwira ntchito bwino.Tiyenera kuyang'ana bokosi loyikapo zinthu ndi ma flanges kuti tidziwe ngati pali kutayikira kapena ayi.Chifukwa chake ngati pali zolakwika mu valavu ndiye tiyenera kuchitapo kanthu kuti tichitenso

Momwe mungayang'anire valavu yowongolera mukalandira kuchokera kwa wopanga?

• Kuwongolera kofananira pamwamba
• Yang'anani gudumu la m'manja
• Chomangira thupi la mpando ndi chiwongolero cha mpando ziyenera kufufuzidwa
• Kumaliza kwa ma flanges kuyenera kuyang'aniridwa
• Yang'anani madoko
• Yang'anani kukula kwa thupi la vavu
• Onani kukula kwa mapeto
• Mapeto a nkhope ya flange ndi mfundo za mphete ziyenera kufufuzidwa

• Kukula kwa vavu ya thupi
• Kutalika kwa tsinde ndi nsonga za ulusi ziyenera kufufuzidwa
Woyang'anira malo ayenera kuyang'ana zikalata zoyendera komanso kuwonongeka kwa makina komwe kungachitike panthawi yotumiza.Tiyenera kuyang'ana ngati valve imatumizidwa bwino kapena ayi.
Zinthu zotsatirazi ziyenera kufufuzidwa kuti zitsimikizire ngati valavu yolamulira imatumizidwa bwino
• Mavavu onse atsanulidwe ndi madzi oyezera ndipo ayenera kuyanika pambuyo poyezetsa madzi
• Mapeto ake ndi ma weld flanges a ma valve ayenera kukhala ndi zovundikira, ndipo kutalika kwake kukhale kofanana ndi m'mimba mwake wakunja kwa flange ndikukhalanso wandiweyani.
• Mbali yokwezeka ya nkhope ya flange ndi nkhokwe ya mphete iyenera kuphimbidwa ndi mafuta olemera.Disiki yolemetsa yoteteza chinyezi iyenera kuyikidwa pakati pa nkhope yopaka mafuta ndi chivundikirocho.Kutalika kwa disc kuyenera kukhala kofanana ndi mainchesi amkati a mabowo a bawuti
• Nsonga za mavavu okhala ndi ulusi ndi socket weld end ziyenera kutetezedwa ndi zisoti zapulasitiki zothina
