EN545 Standard: Ductile Iron Socket uye Spigot Pipe & Socket Dimensions

1. Ductile Iron Sliding Flexible Joint

Rudzi rwemajoini rwakajairika kuneductile simbi pombi, T-joint inoshandisa simba rekubata pakati perin'i yerabha nesoketi nespigot (zvinokonzerwa nekudzvanywa kwemvura panguva yekuisa) kuti igadzire chisimbiso chinodzivisa mvura. Dhizaini yesoketi inotarisa nzvimbo uye kona yekutsauka kwerin'i yerabha, zvichibvumira kugadziriswa kune mamwe magadzirirwo ehwaro uye kupa mwero wakati wekudzivirira kudedera. Ine chimiro chiri nyore, kuiswa kuri nyore, uye hunhu hwakanaka hwekuvhara. Zvisinei, chinetso chayo ndechekusagona kwayo kudzivirira kutsvedza kwepombi, sezvo joini isingakwanise kumira masimba e axial. Saka, mapiers ekutsigira anodiwa pamakonhi epaipi kuti adzivirire masimba e axial.

Majoini emasokisi akaita seT anoshandiswa zvakanyanya mumapaipi esimbi ane ductile. Ari nyore kuisa, haadhuri zvakanyanya, uye anobvumira makona madiki ekutsauka. Kuisa kuri nyore: ingosundira spigot musoketi, uye chisimbiso cherabha chinovhara otomatiki. Izvi zvinokurumidzisa kuiswa uku zvichideredza zvinodiwa nehunyanzvi hwezvishandiso nevashandi. Mufananidzo unotevera ndiwo mucherechedzo wesokisi yesimbi ine ductile uye spigot fitting:

• DE ndiyo dhayamita yekunze yesokisi yepombi yesimbi ine ductile. d1 ndiyo dhayamita yekunze yesokisi yepombi yesimbi ine ductile.
• d2 ndiyo dhayamita yemukati megoroo rerubha rinovhara mudura repombi yesimbi ine ductile.
• d3 ndiyo dhayamita yemukati me soketi yepombi yesimbi ine ductile.
• d5 ndiyo dhayamita yemukati me soketi yesimbi ine ductile uye rin'i yerabha.
• d6 ndiyo dhayamita yemukati yesokisi repombi yesimbi ine ductile iri pamucheto wesokisi.

Munguva yekugadzira nekugadzira, socket end d3 inofanira kunge yakakura zvishoma pane spigot outer diameter DE kuti ive nechokwadi chekuti kuiswa kwacho kwakakodzera. Madhayamita emukati d2 ned3 anofanira kunge ari mukati mekutsungirira. Mhete dzerabha dziri pasocket nespigot dzakavakwa nemusanganiswa werabha rakaoma nerakapfava. Chikamu cherabha chakaoma chinopa rutsigiro rwakakosha uye pakati pepombi, zvichiita kuti rin'i yerabha iomerwe zvakanaka kuti igadzire preload ye 1-5 MPa, kudzivirira kubuda kwemvura mukati mepombi. Sezvo kumanikidzwa kwemvura mukati mepombi kuchiwedzera, rin'i yerabha inowedzera kushata, ichiwedzera kumanikidzwa kwekubatana kusvika 15-25 MPa, zvichigadzira simba rekuwedzera kumanikidzwa uye kusimbisa chisimbiso chepombi.

2. Ductile Iron PipeKureba

Hurefu hunoshanda hwemapaipi esimbi akagadzirwa nesimbi pasi peEN545 hunosvika mamita matanhatu, chiyero chakajairika chinoshandiswa nevagadziri vazhinji munyika nekunze kwenyika. Kuti zvive nyore kutakurwa kwemakontena, mapaipi akagadzirwa neChina anowanzo kuve akareba mamita 5.6 kana 5.7, sezvakabvumiranwa nevatengesi nevatengi. Mapaipi akagadzirwa neIndia anowanzove akareba mamita 5.5.
