Chii chinonzi Double Flange Butterfly Valve?

Iyovharafu yeshavishavi ine flange mbiriivharuvhu remashavishavi rakagara rakasimba rine maflange akabatanidzwa kumativi ese, zvichibvumira kubatana zvakananga nepaipi pasina mamwe maadaptha. Kufanana nemavharuvhu ese emashavishavi akagara akasimba, ivharuvhu rinotenderera nekota: dhisiki rakatenderera rakaiswa pakati pemuviri rinoshanda senzira yekuvhara, rakabatana neactuator kana mubato kuburikidza neshaft yepakati. Kutenderera kwakazara kwemadhigirii makumi mapfumbamwe kunovhura kana kuvhara vharuvhu zvizeresevhisi yekuzviparadzanisa nevamwe.

Kana dhisiki ikasatenderera kusvika pakutenderera kwekota, vharuvhu inenge yakavhurika zvishoma - zvichiita kuti ive nechokwadi chekutimutemo wekuyerera kwemvurapamakona akasiyana-siyana ekuvhura. Chigaro cherabha chakanyatsoiswa zvakananga mumuviri, zvichiita kuti chivhariso chive chakavimbika kumativi ese, kusanganisira kuomarara.mamiriro ekushanda kwevacuum.

Mavharuvhu eNortech double flange butterfly akagadzirwa ane saizi yakareba inoenderana neEN 558-1 Series 13, zvichiita kuti akwanise kushandiswa mumabasa akasiyana-siyana anosanganisira ma network ekugovera mvura, nzvimbo dzekuchenesa mvura, madhamu, nzvimbo dzemagetsi, uye masisitimu emapaipi ane dhayamita hombe. Vharuvhu iyi inogona kushandiswa sevharuvhu yekuparadzanisa, pombi yekubuditsa mvura pamucheto wepaipi, kana mudziyo wekudzora kuyerera kwemvura. Kune mapaipi ane dhayamita hombe, gadziriso yeflange mbiri ndiyo sarudzo yakajairika.

Chati yeCV/KV yevharuvhu reshavishavi rakagara rakapfava rine flange mbiri inowanikwa kana ukaikumbira.

Kutarisana kwenguva refu neEN 558-1 Series 13— dhizaini yeflange mbiri inopa kubatana kwakasimba, kunozvitsigira kwakakodzera zvakanyanya mapaipi ane dhayamita hombe uye mashandisirwo emagetsi anomhanya-mhanya uko kugadzikana uye kurongeka kwemavharuvhu kwakakosha.

Zvinhu zvikuru zvevharuvhu yeshavishavi ine flange mbiri

Kuvaka kudiki — huremu hushoma, nzvimbo shoma yekuchengetera zvinhu uye nzvimbo yekuisa

Mugodhi wepakati, 100% chisimbiso chakasimba chebubble-tight, chero nzira yekuisa

ISO 5211 flange yepamusoro - otomatiki iri nyore uye kugadzirisa actuator

Muviri wese une chibooreso — kuramba kuyerera kwemvura kwakaderera

Nzira yekuyerera isina maburi — iri nyore kuchenesa uye kuuraya utachiona, yakakodzera mvura yekunwa

Muviri wakaputirwa nerabha — mvura haimbobati muviri wesimbi

Dhizaini yedhisiki isina pin — inobvisa nzira dzekubuda kwemvura padhisiki

Torque inoshanda zvishoma — sarudzo yeactuator isingadhuri

Mabheringi ane PTFE — haana kugadziriswa, hapana mafuta anodiwa

Chigaro cherabha chakasungirirwa chakasungirirwa pamusoro pemuviri — chisimbiso chakasimba, chakakodzera kushandiswa kwevacuum uye basa rekupedzisira
