Itondekanya ry'imiyoboro ifatanye:
NPT, PT, na G byose ni insinga.NPT ni umugozi wa 60 ° umuyoboro wa taper uri murwego rwabanyamerika kandi ukoreshwa muri Amerika ya ruguru.Ibipimo byigihugu murashobora kubisanga muri GB / T12716-2002m.
PT ni umugozi wa 55 ° ufunze umuyoboro wa pipe, ni ubwoko bwurudodo rwa Wyeth kandi rukoreshwa cyane mubihugu byu Burayi.Kaseti ni 1:16.Ibipimo byigihugu murashobora kubisanga muri GB / T7306-2000.(Ahanini ikoreshwa mubushyuhe bwinshi, sisitemu yumuvuduko mwinshi hamwe na sisitemu yo gusiga)
G ni 55 ° idafite urudodo rufunga imiyoboro, ni ubwoko bwumugozi wa Wyeth.Ikimenyetso nka G gisobanura umugozi wa silindrike.Ibipimo byigihugu birashobora kuboneka muri GB / T7307-2001 (ahanini bikoreshwa mumiyoboro y'amazi na gaze hamwe n'umuvuduko uri munsi ya 1.57MPa).G nizina rusange ryurudodo, rusanzwe ruzwi nkumuzingi.Nukuvuga, urudodo rutunganywa hejuru ya silindrike.ZG izwi cyane nka pipe cone, ni ukuvuga, urudodo rutunganyirizwa hejuru yubuso, kandi urwego rwigihugu rwaranzwe na Rc (umugozi wimbere wa cone).Byombi G umugozi na Rp ni 55 ° insinga ya silindrike.Rp nizina rya kode ya ISO.
Igice cya GB cyibipimo byubushinwa bihwanye na ISO mpuzamahanga.Ibisobanuro ni ibi bikurikira:
1. Guhuza urudodo rwimbere rwa silindrike (Rp) hamwe nu mugozi wo hanze (R1), byitwa "inkingi / cone ikwiye", numero isanzwe yigihugu cyanjye GB / T7306.1-2000, nayo ihwanye na ISO7-1 mpuzamahanga. : "Inkingi / cone ikwiranye" muri 1994 "umuyoboro w'umuyoboro ufunze n'umugozi";
2. Ihuza ryimbere yimbere (Rc) hamwe nu mugozi wo hanze (R2), bita "cone / cone fit", umubare wigihugu cyacu ni GB / T7306.2-2000, ibyo bikaba bihwanye na ISO7- 1 "" cone / cone ikwiranye "muri 1999" umugozi wumuyoboro ufunze kashe ";
3. Ihuza ry'umugozi w'imbere (G) hamwe na silindrike yo hanze (G) byitwa "inkingi / inkingi ikwiranye".Umubare usanzwe wigihugu cyacu ni GB / T7307-2001 "55 ° umugozi udafunze".Ibipimo ngenderwaho bihwanye Igice cya mbere cyurwego mpuzamahanga ISO228-1: 1994 "Urudodo rudafunze-rudodo rudasanzwe" ni "Kwihanganirana no kwerekana ibimenyetso", ariko amahame yigihugu cyanjye ntabwo asaba ko hakoreshwa insinga zifunze hamwe nududodo tudafunze. , ni (Rp / G);
1. Amazi akonje hamwe na sisitemu yo gufata imiyoboro ihuza umurongo mugihe diameter ya pipe iri munsi cyangwa ingana na 50mm.
2. Imashini ifata imiyoboro ikoreshwa mugutunganya urudodo kandi amavuta yimashini adasanzwe akoreshwa mumavuta.Amazi cyangwa andi mazi ntabwo yemerewe gusimbuza amavuta.
3. Amavuta ya firimu hamwe ninsinga zikoreshwa mugufunga imiyoboro no gupakira, naho kaseti ya Teflon ikoreshwa muguhuza ibikoresho.Ntabwo byemewe kuzana ipaki mu muyoboro mugihe uhambiriye umugozi.
4. Gukata umuyoboro bigomba gukorwa hakoreshejwe gukata cyangwa hackaw.Oxygene acetylene cyangwa imashini ikata ntibyemewe.Gutandukana kw'isura ya nyuma yo gukata ntibigomba kurenza 1% ya diameter yo hanze y'umuyoboro, kandi ntigomba kurenza 3mm.
5. Kugirango hamenyekane byibuze uburebure bwurukuta rwumuzi wurudodo, rugomba kuba rwibanze kumuzingi wimbere wubuso bwanyuma bwigice cyumuyoboro, kandi gutandukana kumutwe wa axial hamwe na axial tile yumutwe wumuyoboro bigomba kugenzurwa cyane, kuko yaba ari parallel parallel gutandukana cyangwa gutandukana kwa axial, Byombi bizagabanya cyane ubunini bwurukuta rwumuyoboro, bityo bigabanye imbaraga zumuyoboro.
Byemerewe gutandukana gutunganya imiyoboro
Diameter ya nominal (mm) Gutandukana kuburinganire (mm) Gutandukana (mm)
1 ≤32 0.3 0.3 / 100
2 40 ~ 65 0.4 0.4 / 100
3 80 ~ 100 0.5 0.5 / 100
4 125 ~ 150 0.6 0.5 / 100
6. Umuyoboro umaze gutunganywa umaze gutunganywa, genzura ukoresheje igikoresho cyo gupima.Niba hari imiyoboro ihuza imiyoboro imwe, nibyiza guhuza imiyoboro.Urwego rwo kwidegembya rugomba gukururwa gusa n'intoki, kandi ntirukwiye kurekurwa cyane niba ibyuma byujujwe byinjiye. Niba ugumye, ushobora gukomanga umuyoboro ukoresheje inzara y'ibiti.Niba idashobora gukururwa cyangwa umugozi urakomera, irashobora gukurwaho gusa.Kurekura ku gahato ntibyemewe.
7. Urudodo rudodo rugomba kuba rufite isuku kandi rusanzwe.Urudodo rwacitse cyangwa rwabuze ntirugomba kurenga 10% yumubare winyuzi.Igice cya galvanised hejuru yinyuma yumuyoboro kigomba kurindwa.Ibice byangiritse bigomba kuvurwa hakoreshejwe uburyo bwo kurwanya ruswa.
8. Guhuza urudodo Umuzi wumugozi wumuyoboro nyuma yo gushiraho umuyoboro ugomba kuba ufite insinga 2 ~ 3 zerekanwe, kandi insinga zirenze urugero zigomba guhanagurwa no kuvurwa hakoreshejwe uburyo bwo kurwanya ruswa.
