I-Rubber Expansion Joint

Ijoyinti yokwandisa irabha, okwaziwa nangokuthi ijoyinti yenjoloba, iwuhlobo lwejoyinti lokunweba

1. Izikhathi zokufaka isicelo:

Ijoyinti lokunwetshwa kwenjoloba liwukuhlanganisa okuguquguqukayo kwamapayipi ensimbi, akhiwe yindilinga yenjoloba eqiniswe ngongqimba lwenjoloba yangaphakathi, indwangu yentambo yenayiloni, ungqimba lwerabha lwangaphandle kanye ne-flange yensimbi exekethile. Inezici zokumelana nengcindezi ephezulu, ukunwebeka okuhle, ukugudluka okukhulu, ukuchezuka kwepayipi elilinganiselayo, ukumuncwa kokudlidliza, umphumela omuhle wokunciphisa umsindo nokufakwa okulula; Ingasetshenziswa kabanzi ekunikezeni amanzi kanye nokukhipha amanzi, amanzi ajikelezayo, i-HVAC, ukuvikelwa komlilo, ukwenza iphepha, imithi, i-petrochemical, umkhumbi, iphampu yamanzi, i-compressor, fan kanye nezinye izinhlelo zamapayipi.

2.Ungagcina kanjani ijoyinti lokunwetshwa kwerabha:

I-transmission medium inquma impilo yejoyinti lokunwetshwa kwenjoloba. Ama-acids abolayo, izisekelo, amafutha namakhemikhali anomthelela kumpushana oqinile, insimbi nesitimu kugesi. Zingasetshenziselwa ukushintsha impahla ukulawula imidiya ehlukahlukene yokudlulisela, okuwukugcina i-valve ngezinkinga zezinto ezibonakalayo. Izinkinga zokufaka Ngesikhathi sokufakwa, indawo yokufaka izovezwa elangeni, elizolimaza irabha nobudala, ngakho-ke kuyadingeka ukumboza inhlanganisela yokwandisa irabha ngesendlalelo sefilimu ye-sunscreen. Ngokuphathelene nokufakwa, ijoyinti yokwandisa irabha ngokwayo inokufakwa okuphezulu kokuphakama, futhi imfuneko yokucindezela inkulu kakhulu, ngakho-ke i-joint yokwandisa irabha ingafakwa ngalesi sikhathi. Lezi zindlela ezimbili ziphinde zisebenzisa amandla angaphandle ukuze kugcinwe inhlanganisela yokwandisa irabha. Ngesikhathi sokusebenza, lapho i-joint yokwandisa irabha iqala ukusebenza, kuyadingeka ukuhlola njalo ukuqina kwe-bolt yengxenye yokufaka yejoyinti yokwandisa irabha. Uma isetshenziswe isikhathi eside, izikulufu zizogqwala futhi ziphule, ngakho-ke zidinga ukushintshwa. Le ndlela yesondlo ingeyokushintshwa kwezingxenye ezincane, ezingagcina kakhulu izingxenye ezinkulu.

3. Indlela yokufaka:

Imodeli, ukucaciswa nokucushwa kwepayipi lejoyinti yokunweba kufanele ihlolwe ngaphambi kokufakwa ukuze kuqinisekiswe ukuthi iyahlangabezana nezidingo zokuklama. Ngejoyinti lokunweba elinomkhono ongaphakathi, kuzoqashelwa ukuthi isiqondiso somkhono ongaphakathi kufanele sihambisane nesiqondiso sokugeleza kwe-medium, futhi indiza ezungezayo yehinge yohlobo lokunwebeka lwe-hinge izohambisana nendiza ezungezayo. Ngesinxephezelo esidinga "ukuqina okubandayo", izingxenye ezisizayo ezisetshenziselwa ukuguqulwa kwangaphambili akufanele zisuswe kuze kube yilapho ipayipi ifakiwe. Akuvunyelwe ukulungisa ukufakwa ngenxa yokubekezelela ipayipi ngokuguqulwa kwejoyinti lokunweba likathayela, ukuze kungathinti umsebenzi ojwayelekile wesinxephezelo, kuncishiswe impilo yesevisi futhi kwandise umthwalo wesistimu yamapayipi, izinto zokusebenza kanye namalungu asekelayo. . Ngesikhathi sokufakwa, i-welding slag ayivunyelwe ukuchaphaza phezu kwe-wave case, futhi i-wave case ayivunyelwe ukuhlupheka ngenxa yokulimala komshini. Ngemuva kokufakwa kwesistimu yepayipi, izingxenye ezisizayo zokumisa kanye nezinsimbi ezisetshenziselwa ukufakwa nokuthutha endaweni ehlanganisiwe yokwandisa zizosuswa ngokushesha ngangokunokwenzeka, futhi idivayisi yokumisa izolungiswa endaweni ecacisiwe ngokuvumelana nezidingo zokuklama, ukuze uhlelo lwamapayipi lunamandla okwanele okunxeshezelwa ngaphansi kwezimo zemvelo. Izakhi ezinyakazayo zejoyinti lokunweba ngeke zivinjwe noma zivinjelwe izingxenye zangaphandle, futhi ukusebenza okuvamile kwengxenye ngayinye ehambayo kuzoqinisekiswa. Ngesikhathi sokuhlolwa kwe-hydrostatic, ukwesekwa kwepayipi lesibili elingaguquki ekugcineni kwepayipi elihlangene lokunweba kuzoqiniswa ukuze kuvinjelwe ipayipi ukuthi linganyakazi noma lijikeleze. Ngesinxephezelo kanye nepayipi layo lokuxhuma elisetshenziselwa i-gas medium, qaphela ukuthi kudingekile yini ukwengeza ukwesekwa kwesikhashana lapho ugcwalisa amanzi. Okuqukethwe kwe-ion ye-96 yesisombululo sokuhlanza esisetshenziselwa ukuhlolwa kwe-hydrostatic akufanele kudlule i-25PPM. Ngemuva kokuhlolwa kwe-hydrostatic, amanzi anqwabelene kugobolondo lamagagasi azokhishwa ngokushesha futhi indawo engaphakathi yegobolondo lamagagasi izoshaywa umoya.

4.Izici zejoyinti lokunwetshwa kwerabha:

Izihlanganisi zokunweba zenjoloba zisetshenziswa ngaphambili nangemuva kwephampu yamanzi (ngenxa yokudlidliza); Ngenxa yezinto ezihlukahlukene, irabha ingafinyelela imiphumela ye-asidi ne-alkali ukumelana, kodwa izinga lokushisa layo lokusetshenziswa ngokuvamile lingaphansi kwe-160 ℃, ikakhulukazi lifika ku-300 ℃, futhi ingcindezi yokusebenzisa ayinkulu; Amalunga aqinile awanakho ukumelana ne-asidi ne-alkali. Ezikhethekile zingenziwa ngensimbi engagqwali. Izinga lokushisa lokusebenza nokucindezela kuphakeme kunamajoyinti okwandisa irabha. Amalunga okukhulisa irabha ashibhile kunamajoyinti aqinile. Kulula ukuzifaka ngenhla; Ijoyinti lokunwetshwa kwenjoloba lisetshenziselwa kakhulu ukunciphisa ukudlidliza kwepayipi.
