201 202 310S 304 316 Umutako wo gusudira wasizwe neza nu ruganda rukora ibyuma
Gutondekanya imiyoboro ihujwe:
NPT, PT, na G byose ni insinga.NPT ni umuyoboro wa 60 ° wa taper uhuza urwego rwabanyamerika kandi ukoreshwa muri Amerika ya ruguru.Ibipimo byigihugu murashobora kubisanga muri GB / T12716-2002m.
PT ni umugozi wa 55 ° ufunzwe neza, ni ubwoko bwurudodo rwa Wyeth kandi rukoreshwa cyane mubihugu byu Burayi.Ikariso ni 1:16.Ibipimo byigihugu murashobora kubisanga muri GB / T7306-2000.(Byinshi bikoreshwa mubushyuhe bwo hejuru, sisitemu yumuvuduko mwinshi hamwe na sisitemu yo gusiga)
G ni 55 ° idafite urudodo rufunga imiyoboro, ni ubwoko bwumugozi wa Wyeth.Ikimenyetso nka G kigereranya urudodo.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, ruzwi nkumuzingi.Nukuvuga, urudodo rutunganijwe hejuru ya silindrike.ZG ikunze kwitwa umuyoboro wa cone, ni ukuvuga, urudodo rutunganyirizwa hejuru yubuso, kandi urwego rwigihugu rwerekanwe nka Rc (umugozi wimbere wimbere).Byombi G urudodo na Rp ni 55 ° silindrike ya pipine.Rp nizina rya code 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 bikwiye", numero yigihugu cyanjye GB / T7306.1-2000, nayo ihwanye na ISO7-1 mpuzamahanga. : "Inkingi / cone ikwiranye" muri 1994 "insinga y'umuyoboro ifunze hamwe 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" insinga y'umuyoboro ifunze hamwe nuudodo ";
3. Guhuza urudodo rwimbere rwimbere (G) hamwe nu mugozi wo 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" 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 ya 50mm.
2. Imashini itanga imiyoboro ikoreshwa mugutunganya urudodo kandi amavuta yimashini yihariye akoreshwa mumavuta.Amazi cyangwa andi mazi ntibyemewe gusimbuza amavuta.
3. Amavuta ya firimu na hemp bikoreshwa mugufunga imiyoboro no gupakira, naho kaseti ya Teflon ikoreshwa muguhuza ibikoresho.Ntabwo byemewe kuzana ibipaki mu muyoboro mugihe uhambiriye umugozi.
4. Gukata umuyoboro bigomba gukorwa hakoreshejwe gukata cyangwa hackaw.Oxygene acetylene cyangwa imashini ikata ntibyemewe.Gutandukana guhindagurika kumaso yanyuma yo gukata ntibigomba kurenza 1% ya diametre yinyuma yumuyoboro, kandi ntigomba kurenza 3mm.
5. Kugirango hamenyekane byibuze uburebure bwurukuta rwumuzi wurudodo, rugomba kuba rwibanze kumuzingi wimbere wubuso bwanyuma bwigice cyumuyoboro, kandi gutandukanya umurongo wa axial hamwe nu murongo wa axe wumugozi bigomba kugenzurwa cyane, kuko yaba ari axial 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 utunganijwe, reba neza hamwe nigikoresho cyo gupima.Niba hari imiyoboro ihuza imiyoboro imwe, nibyiza guhuza imiyoboro.Urwego rwo kwidegembya rugomba gukururwa gusa n'intoki, kandi ntirukwiye kurekurwa mugihe imiyoboro ya pipine yashizwemo. Niba ugumye, urashobora gukubita umuyoboro ukoresheje inzara.Niba bidashobora gukururwa cyangwa umugozi urakomera, birashobora gukurwaho gusa.Kurekura ku gahato ntibyemewe.
7. Urudodo rudodo rugomba kuba rufite isuku kandi rusanzwe.Urudodo rwacitse cyangwa rwabuze ntirugomba kurenga 10% yumubare wuzuye.Igice cya galvanised hejuru yinyuma yumuyoboro kigomba kurindwa.Ibice byangiritse bigomba kuvurwa no 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 no kurwanya ruswa.
