I-Metal Expansion joint is a compensator efakwe ngokuthe ngqo kumbhobho we-single-phase okanye i-multiphase fluid.Ubukhulu becala yenziwe ngomkhono (umbhobho ongundoqo), iqokobhe, imathiriyeli yokutywina, njl. njl. umngxuma wokutywina uvalwa ngokubanzi ngemathiriyeli yegraphite yobushushu obuphezulu, enezibonelelo zoku, ukuthambisa, ukutywinwa kobushushu obuphezulu, njl. njl. Buyekeza ukwandiswa kwe-axial kunye nokucutheka kombhobho kunye nembuyekezo ye-axial kuyo nayiphi na i-engile.Amalungu okwandisa isinyithi aneempawu zomthamo omncinci kunye nembuyekezo enkulu.Isetyenziswa ngokubanzi kwimibhobho yezothutho ekwakheni iinqanawa, ukufudumeza kwedolophu, isinyithi, imigodi, ukuveliswa kwamandla, i-petroleum, imboni yeekhemikhali, ukwakhiwa kunye namanye amashishini.
Umkhono ongaphakathi wodidi olutsha lwentsimbi yokwandisa idibaniso idityaniswe nombhobho, kwaye yamkele umgaqo kunye nolwakhiwo lokutywinwa koxinzelelo lwesiqu.Iyakwazi ukutyibilika ngokukhululekileyo kwiqokobhe kunye nokwandiswa kunye nokucutheka kombhobho, kwaye inokuhlangabezana neemfuno zokutywinwa kwanoma yimuphi umbhobho.Izinto ezintsha zokwenziwa zisetyenziselwa phakathi kwegobolondo kunye nomkhono wangaphakathi ukutywina, ezinokumelana nokushisa okuphezulu, ukuthintela ukubola kunye nokuxhathisa ukuguga.Iqondo lokushisa elisebenzayo li-40 ℃ ukuya kwi-400 ℃, elingenako ukumisela kuphela i-axial sliding, kodwa iqinisekisa ukuba i-medium kwipayipi ayivuzi.Isixhobo esitsha sokwandiswa kwesinyithi siyilwe kunye nesixhobo esichasene nokuqhekeka, esinokuthi siqinisekise ukuba asiyi kutsalwa ngaphandle xa sikhula kwindawo elinganiselweyo, ukuze kuphuculwe uzinzo lwenethiwekhi yonke yombhobho.Ikhonkco entsha yokwandisa isinyithi ayinayo imfuneko yomxholo we-chloride ion, kwaye ifaneleke ngokukodwa kwiinkqubo ezine-chloride ion ezigqithisileyo kwindawo ephakathi okanye engqongileyo.
Ukwandiswa kwesinyithi esidibeneyo sisebenza kuxinzelelo lobunjineli obuphakathi ≤ 2.5MPa, ubushushu obuphakathi -40 ℃ ~ 600 ℃.Umxhasi we-sleeve wamkela into entsha yokutywina ikhonkco yegraphite eguquguqukayo, eneempawu zamandla aphezulu, i-coefficient ephantsi ye-friction (0.04 ~ 0.10), akukho kuguga, isiphumo esihle, ukugcinwa kakuhle, njl njl. , kwaye ubomi bokudinwa bulingana nobombhobho.Emva konyango olukhethekileyo, indawo yokutyibilika inokusebenza kakuhle kwe-corrosion emanzini anetyuwa, isisombululo setyuwa kunye nezinye iindawo, ezingaphezulu kwamaxesha angama-50 ngaphezu kwe-austenitic stainless steel.
Izizathu zokuba kutheni iintsimbi zokwandiswa kweentsimbi zisetyenziswa ngokubanzi:
2. I-sleeve compensator ayinayo imfuneko yomxholo we-chloride ion, kwaye ifaneleke ngokukodwa kwiinkqubo ezine-chloride ion ezigqithisileyo kwindawo ephakathi okanye engqongileyo.
3. I-sleeve compensator yahlulwe yaba yindlela enye yembuyekezo kunye nesakhiwo sembuyekezo yeendlela ezimbini.Ulwakhiwo lwembuyekezo yeendlela ezimbini luphawulwa ngokuba imikhono yokutyibilika kwiziphelo zombini zombuyekezi ihlala isilayidi ngokukhululekileyo kungakhathaliseki ukuba i-medium iphuma kumbuyiseli, ukwenzela ukuba kuphunyezwe imbuyekezo yeendlela ezimbini kunye nokwandisa inani lembuyekezo.
