Vharuvhu yeBhabhatafura yeKubvisa Katatu DN150–DN500 Lug PN25/PN40 — CE-PED uye ATEX Certified Delivery kuMusika weEurope

Pfupiso yeChigadzirwa

Nortech Engineering Corporation yapedza kugadzira mavharuvhu matatu emhando ye "triple offset butterfly valve units" ane saizi DN150, DN250, DN400, uye DN500, mumhando dze "pressure classes" PN25 nePN40, ese ari mu "lug type end connection configuration". Dhizaini iyi ine 100% bi-directional tightness pasina kudonha kwemvura pasi pemamiriro ezvinhu akajairwa ekugara uye ekurerutsira kumanikidzwa - chiyero chekushanda chinodiwa neEuropean process plant specifications. "Lug body profile" inobvumira kuiswa kwe "dead-end service" pasina "downstream flange", ichipa ma "flexible piping configuration" evanjiniya vemafekitori.

Kutakura uku kwakagadzirirwa musika wekuEurope uye kunoenderana zvizere neCE-PED (Pressure Equipment Directive) uye zvinodiwa zvekuisa muzvikamu zveATEX kuti zvishandiswe munzvimbo dzine mhepo dzinoputika.

Magadzirirwo ehunyanzvi

Muviri nebhoneti zvinogadzirwa musimbi yekabhoni ye1.0619+N, yakagadzirwa kuti ive nechokwadi chekuti mativi ese akaenzana ne triple-offset geometry uye kuti zvigaro zvinosangana zvakanaka. Disk iyi inogadzirwa musimbi isina ngura ye1.4408 austenitic (CF8M yakaenzana), ichipa simba rekudzivirira ngura pamhando dzakasiyana dze process media. Dumbu rayo rinogadzirwa kubva kusimbi isina ngura ye17-4PH precipitation-hardening, yakasarudzwa nekuda kwesimba rayo guru uye simba rekudzivirira kuneta pasi pe cyclic torque loads.

Sisitimu yezvigaro zvesimbi yakagadzirwa neStellite yakasimba pamusoro pezvigaro kuti isakwekwe, isatsvedze, uye isakuvadzwe nekupisa kwakanyanya. Rin'i yechisimbiso inosanganisa simbi isina tsvina yeS32750 super duplex negraphite laminate layer, ichipa kushanda kwesevha kusingatsvedzeri moto uye yakasimba panguva yekushanda kwesevha. Kubatana kwekupedzisira kwakabatana neEN 1092-1 flanging dimensions; dhizaini yakajairika EN 593.

Kunyorera & Kutumira

Batch iyi yakapihwa kune muparidzi wekuEurope anoshanda muzvikamu zvekuchenesa, petrochemical, uye kugadzira simba. Chitupa cheATEX butterfly valve chinokodzera mayuniti aya kuti akwanise kuiswa munzvimbo dzine njodzi dzeZone 1 neZone 2 uko kudzora njodzi yekupisa kuri kudikanwa. Magadzirirwo akawanda evashandisi akabatanidzwa mukutumira - magiya emaoko eDN400 neDN500 saizi yakakura, uye mapakeji epneumatic actuator eDN150 neDN250 units - achifukidza huwandu hwese hwezvinodiwa zve otomatiki panzvimbo.

Semutengesi we triple offset butterfly valve, Nortech inopa mapakeji evharuvhu anoenderana neCE-PED ezvitoro zveEurope nemapurojekiti, pamwe nekugona kuteverwa kwezvinhu zvese uye kuongororwa kwevamwe vanhu kana zvikakumbirwa.
