ASTM A995 6A dual plate check valve ivharuvhu yakagadzirwa neASTM A995 6A zvinhu.

ASTM A995 6A super duplex simbi isina tsvina yakaonekwa muchimiro chesimbi yakakandwa pakati pemakore ekuma1980. Chinangwa chekusimudzira ndechekugadzirisa midhiya yakaoma (ine chloride, CO2, H2S, nezvimwewo) zvinhu zvinoshandiswa muminda yemafuta epasi pegungwa uye gasi, pachinzvimbo chekusagadzikana kwenzvimbo uye yunifomu yekudzivirira ngura. Zeron25 isina kukwana (25Cr-6Ni-2Mo) duplex simbi isina tsvina. ASTM A995 6A simbi yakashandiswa muminda yakawanda, kunyanya nekuda kwesimba rayo repamusoro uye kuramba kune corrosion yemunharaunda uye kushushikana kwekuora kwechloride. Simbi ine yakakwira nitrogen, ine mhedzisiro yekudzikamisa austenite. Kunyangwe zviri mukati mechromium uye molybdenum zvinhu zvakakwirira, nekuda kwekuita kwenitrogen, kana tembiricha yakakwira kupfuura 1050 ℃, huwandu hweferrite huchiri pedyo ne50%.

Nekuda kwemaitiro ayo akanaka emuchina uye kushorwa kwemarara, duplex simbi isina tsvina yakashandiswa zvakanyanya muinjiniya yekumahombekombe uye kuvaka ngarava, senge gasi remugungwa remafuta, masisitimu emvura, pombi dzemvura yakadzika, mapuratifomu ekuchera ekunze, zvicherwa zvepasi pegungwa, zvikepe zvehondo uye ngarava dzakakosha Mira. Kunyange zvazvo ASTM A995 6A duplex Stainless steel material ine high corrosion resistance, ichiri biologically inert material, iyo inogona chete kudzikamisa mwero we microbial corrosion, uye haikwanise kugadzirisa kukuvadza kunokonzerwa ne microbial corrosion kubva pamudzi chikonzero.

Iyo mbiri-plate cheki chevhavha yekuvhura uye yekuvhara nhengo inovhurwa kana kuvharwa nepakati inoyerera uye simba rekudzivirira kuyerera kwemashure kwevharuvhu kunonzi cheki cheki. Cheki mavharuvhu mavharuvhu otomatiki, anonyanya kushandiswa pamapombi ane nzira imwe chete kuyerera kwenhau, achibvumira chete midhiya kuti ifambe munzira imwe kudzivirira tsaona.

Newsway Valve ASTM A995 6A mbiri plate cheki vharafu kuvhura/kuvhara zvikamu zvinovhurwa kana kuvharwa nepakati kuyerera uye simba kudzivirira yepakati kubva kuyerera ichidzoka. Dual plate cheki mavharuvhu ndeechikamu cheotomatiki mavharuvhu, ayo anonyanya kushandiswa mapaipi ane nzira imwe chete yekuyerera kwe media, uye inongobvumira midhiya kuyerera munzira imwe kudzivirira tsaona. Cheki vharuvhu butterfly ndiro maviri semicircles, uye chitubu inoshandiswa kumanikidza reset. Iyo yekuisa chisimbiso inogona kunge iri yemuviri welding inopfeka-inodzivirira zvinhu kana rubber lining. Iine huwandu hwakawanda hwekushandisa uye chisimbiso chakavimbika.

Kana uchida rumwe ruzivo nezve mavharuvhu ndapota taura nebazi rekutengesa reNSW(newsway valve).

Newsway Valves Materials

NSW valve body uye trim material inogona kupihwa muForged type uye Casting type. Pedyo nesimbi isina tsvina uye kabhoni simbi, isuwo tinogadzira mavharuvhu mune zvakakosha zvinhu zvakaita setitanium, nickel alloys, HASTELLOY®*, INCOLOY®, MONEL®, Alloy 20, super-duplex, corrosion resistant alloys uye urea giredhi zvinhu.
