Iivalvu zihlala ziqhagamshelwa kwimibhobho ngeendlela ezahlukeneyo ezinjengeentambo, iiflange, i-welding, i-clamps, kunye ne-ferrules.Ke, ekukhetheni ukusetyenziswa, ungakhetha njani?
Ziziphi iindlela zokudibanisa iivalve kunye nemibhobho?
1. Uxhulumaniso lwemisonto: Uxhulumaniso lwemisonto yindlela apho iziphelo ezimbini zevalve zicutshungulwa zibe yimicu yangaphakathi okanye imicu yangaphandle ukuze idibanise nombhobho.Ngokuqhelekileyo, iivalve zebhola ezingaphantsi kwee-intshi ezi-4 kunye neevalve zeglowubhu, iivalve zesango kunye neevalvu zokujonga ngaphantsi kwee-intshi ezi-2 zitsalwa kakhulu.Isakhiwo soxhulumaniso esinentambo silula, ubunzima bulula, kwaye ukufakela kunye nokuqhaqha kukulungele ukugcinwa kunye nokutshintshwa.Ekubeni i-valve iya kwanda phantsi kweempembelelo zeqondo lokushisa eliphakathi kunye nobushushu obuphakathi ngexesha lokusetyenziswa, ukuqinisekisa ukusebenza kakuhle kokutywinwa, i-coefficients yokwandiswa kwezinto ezimbini ekupheleni kokudibanisa kufuneka iqwalaselwe ngokupheleleyo.Kusenokubakho amajelo avuzayo amakhulu kuqhagamshelo olunemisonto, ngoko ke izitywini, iiteyiphu zokutywina okanye izihluzi zingasetyenziselwa ukubhloka la matshaneli ukwandisa ukusebenza kokutywina.Ukuba inkqubo kunye nempahla ye-valve yomzimba inokudityaniswa, inokutywinwa emva kokudityaniswa kwentambo.Ukwabelana ngesondo kuya kuba ngcono.
2. Uxhulumaniso lweFlange: Uxhulumaniso lweFlange yeyona ndlela ixhaphakileyo yokudibanisa kwiivalvu.Ukufakela kunye nokuchithwa kulungeleka kakhulu, kwaye uxhumano lwe-flange luthembekile ekutywinweni, oluxhaphake kakhulu kwi-high-pressure kunye ne-diameter-diameter valves.Nangona kunjalo, isiphelo seflange sinzima, kwaye iindleko ziphezulu.Ngaphezu koko, xa iqondo lobushushu lidlula i-350 ℃, ngenxa yokunyuswa kweebholiti, iigaskets kunye neeflanges, umthwalo weebholiti uya kuncitshiswa kakhulu, kwaye uqhagamshelo lweflange noxinzelelo olukhulu lunokuvuza, olungafanelanga ukusetyenziswa.
3. Ukudibanisa okudibeneyo Ukudibanisa okudibeneyo ngokuqhelekileyo kuneentlobo ezimbini zezakhiwo: i-socket welding kunye ne-butt welding.Ngokuqhelekileyo, i-socket welding isetyenziselwa iivalve zoxinzelelo oluphantsi.Ukwakhiwa kwe-welding ye-socket welding valves kulula ukuyiqhuba kwaye kulula ukuyifaka.I-butt welding isetyenziselwa i-valve yoxinzelelo oluphezulu ineendleko eziphezulu, kwaye i-welding ifuna ukukhuliswa ngokomgangatho wepayipi, ekunzima ukuyiqhuba, kunye nenkqubo ye-welding kunye nofakelo nayo inzima kakhulu.Kwezinye iinkqubo, uvavanyo lwe-radiographic olungonakalisi luyafuneka kwakhona kwi-welding yoqhagamshelwano.Xa iqondo lokushisa lidlula i-350 ° C, umthwalo weebholiti uya kuncitshiswa kakhulu ngenxa yokuphumla kwe-creep of the bolts, i-gaskets kunye ne-flanges, kunye nokuvuza kunokuthi kwenzeke kwi-flange uxhumano noxinzelelo olukhulu.
4. Uxhulumaniso lwe-Clamp Isakhiwo sokudibanisa i-Clamp sifana ne-flange, kodwa isakhiwo sayo silula kwaye ixabiso eliphantsi lisetyenziswa ngokuqhelekileyo kwimibhobho yococeko kunye nezixhobo.Imibhobho yococeko kufuneka icocwe, kwaye akuvumelekanga ngokungqongqo ukuba kubekho iintsalela zokuvelisa iibhaktheriya, ngoko ke ukudityaniswa kwe-flange kunye noqhagamshelo olunemisonto alufanelekanga, kwaye ukudityaniswa kwe-welding kunzima ukuyifaka kunye nokuqhaqha.Ngoko ke, ukudityaniswa kweeclamp zezona zixhaphakileyo kwimibhobho ekrwada.indlela yoqhagamshelwano.
