Corrosion chimwe chezvinhu zvakakosha zvinokonzeresabutterfly valve kukuvara. Inbutterfly valve kudzivirira,butterfly valve kudzivirira ngura inyaya yakakosha yekufunga nezvayo. Zvesimbibutterfly valves, kurapwa kwepamusoro pekuvhara ndiyo nzira yakanakisisa yekudzivirira inodhura.
Basa resimbibutterfly valve kupfeka kwepamusoro
01. Kudzivirira
Mushure mokunge nzvimbo yesimbi yakaputirwa nepende, simbi yesimbi inenge iri yoga kubva kune zvakatipoteredza. Izvi zvinodzivirira zvinogona kunzi shielding effect. Asi zvinofanirwa kutaurwa kuti pende yakaonda yepende haigone kuita mhedziso yekudzivirira. Nekuti iyo yakakwira polymer ine kumwe kupindira kwemhepo, kana iyo yekupfeka iri mutete kwazvo, ma pores ayo echimiro anobvumira mamorekuru emvura uye okisijeni kupfuura zvakasununguka. Yakapfava-yakavharwabutterfly valves vane zvakaomesesa zvinodikanwa pane ukobvu hweiyo epoxy coating pamusoro. Zvinogona kuonekwa kuti kune akawanda machira kukosha kwakakura kudarika simbi isina kuvharwa. Kuti uvandudze kusapindirana kwechifukidziro, iyo anti-corrosion coating inofanira kushandisa firimu-inogadzira chinhu nemhepo yakaderera permeability uye yakasimba filler ine pfuma huru yekudzivirira, uye panguva imwe chete, nhamba yezvipfeko zvekuputira zvinofanira kuwedzerwa. kuitira kuti kuvhara kunogona kusvika kune imwe hupamhi uye kuva dense uye kwete-porous.
02. Corrosion inhibition
Nekuita zvikamu zvemukati zvekuputira nesimbi, simbi yesimbi inopfuudzwa kana chinhu chinodzivirira chinogadzirwa kuti chivandudze maitiro ekudzivirira ekuvhara.butterfly valvesinoshandiswa kune zvakakosha zvinodiwa inofanirwa kutarisisa kuumbwa kwependi kuti udzivise mhedzisiro yakaipa. Mukuwedzera, simbi yakakandwabutterfly valve inoshandiswa mupombi yemafuta, zvigadzirwa zvekushatisa zvinogadzirwa pasi pekuita kwemamwe mafuta uye kuomesa sipo yesimbi zvinogona zvakare kuita basa re organic corrosion inhibitors.
03. Electrochemical protection
Electrochemical corrosion pasi pefirimu inoitika apo dielectric permeable coating inosangana nesimbi. Shandisa simbi dzine chiitiko chepamusoro pane simbi semazadza mumachira, senge zinc. Ichaita basa rekudzivirira rezvibairo anode, uye zvigadzirwa zvekuora zvezingi ndeye zinc chloride uye zinc carbonate, iyo inozadza gaka re membrane uye kuita kuti membrane ive yakasimba, iyo inoderedza zvakanyanya kuora uye inowedzera hupenyu hwesevhisi.butterfly valve.
Inowanzo shandiswa zvipfeko zvesimbibutterfly valves
01.butterfly valve muviri epoxy resin coating
Ine zvinotevera maitiro:
Corrosion resistance
Epoxy-coated simbi mabara ane yakanaka corrosion resistance, uye iyo bond simba nekongiri yakaderedzwa zvakanyanya. Inokodzera mamiriro eindasitiri munzvimbo dzine hunyoro kana hutsinye midhiya.
kunamatira kwakasimba
Kuvapo kwepolar hydroxyl uye ether bonds inherent in molecular chain of epoxy resins inoita kuti inamire zvakanyanya kune zvakasiyana zvinhu. Epoxy resin ine yakaderera shrinkage panguva yekurapa, uye kushushikana kwemukati kunogadzirwa kudiki, uye inodzivirira pamusoro pekuvhara haisi nyore kudonha nekutadza.
Magetsi zvinhu
Iyo yakaporeswa epoxy resin system ndeye yakanakisa insulating zvinhu ine yakakwira dielectric zvivakwa, pamusoro pekudonha kwekudzivirira uye arc kuramba.
Mold resistance
Yakarapirwa epoxy masisitimu inoshingirira kune akawanda mold uye inogona kushandiswa munzvimbo dzakaoma dzinopisa.
02.butterfly valve ndiro naironi ndiro zvinhu
Mashizha enylon anonyanya kusaita ngura uye akashandiswa zvinobudirira mukushandisa kwakawanda senge mvura, madhaka, chikafu, uye kubvisa munyu.
bonde rekunze
Iyo naironi bhodhi yekuputira inogona kupasa munyu bvunzo, uye iyo yekupfeka haina kusvuuka mushure mekunyudzwa mumvura yegungwa kweanopfuura makore makumi maviri nemashanu, saka hapana ngura kune zvikamu zvesimbi.
abrasion resistance
Iine yakanaka kwazvo kukuvara kusagadzikana.
kukanganisa kuramba
Iko hakuna chiratidzo chekusvuura pasi pesimba rakasimba.
