Iindlela zokuhlanganisa i-valve ezisetyenziswa ngokuqhelekileyo
Iindlela zokuhlanganisa ezisetyenziswa ngokuqhelekileyo zinokuba neentlobo ezintathu, ezizezi, indlela epheleleyo yokutshintsha, indlela yokulungisa kunye nendlela yokudibanisa:
(1) indlela yokutshintshiselana epheleleyo: xa i-valve ihlanganiswe ngendlela epheleleyo yokutshintshiselana, inxalenye nganye yevalve inokuhlanganiswa ngaphandle kokugqoka kunye nokuzikhethela, kwaye imveliso inokuhlangabezana neemfuno zobugcisa ezichaziweyo emva kokuhlanganisana. Ngeli xesha, iinxalenye ze-valve kufuneka zicutshungulwe ngokupheleleyo ngokuhambelana neemfuno zokuyila ukwanelisa ukuchaneka kwe-dimensional kunye nesimo kunye nesicelo sokunyamezela isikhundla. Iinzuzo zendlela yokutshintshiselana epheleleyo yile: umsebenzi wendibano ulula, uqoqosho, abasebenzi abafuni iqondo eliphezulu lobuchule, ukuveliswa kwenkqubo yendibano kuphezulu, kulula ukuququzelela umgca wendibano kunye nombutho wemveliso ekhethekileyo. Nangona kunjalo, xa indibano epheleleyo yokutshintshwa yamkelwa, ukuchaneka komatshini kwamacandelo kufuneka kube phezulu. Ifakwe kwivalve yeglowubhu, ivalve yokukhangela, ivalve yebhola kunye nolunye uhlobo olulula lweklasi yevalve kunye nevalve encinci yedayamitha.
(2) Indlela yokufanisa: i-valve ithatha indlela ehambelanayo yokuhlanganisana, umatshini wonke unokucutshungulwa ngokuchaneka kwezoqoqosho, kwaye emva koko ukhethe ubungakanani kunye nohlengahlengiso kunye nembuyekezo ngexesha lokuhlanganisana, ukuze ufikelele ukuchaneka kwendibano echaziweyo. Umgaqo wendlela yokufanisa iyafana nendlela yokulungisa, kuphela indlela yokutshintsha ubungakanani bendandatho yembuyekezo iyahluka. Owokuqala kukutshintsha ubungakanani beringi yembuyekezo ngokukhetha izincedisi, kwaye lo mva kukutshintsha ubungakanani beringi yembuyekezo ngokunxiba izincedisi. Umzekelo, umbindi ophezulu kunye nohlengahlengiso lwe-gasket yevalve yesango le-wedge ephindwe kabini yemodeli yevalve yolawulo, kunye ne-gasket yokulungelelanisa phakathi kwemizimba emibini yevalve yebhola evulekileyo ikhethwa njengeendawo zembuyekezo kwikhonkco lomlinganiso onxulumene nokuchaneka kwendibano, kunye ukuchaneka kwendibano efunekayo kufezekiswa ngokulungelelanisa ubukhulu kunye nobukhulu be-gasket. Ukuqinisekisa ukuba iindawo zembuyekezo ezisisigxina zinokukhethwa phantsi kweemeko ezahlukeneyo, kuyimfuneko ukwenza iseti yeemodeli zevalvu yolawulo lwe-hydraulic ye-gasket kunye neengxenye zembuyekezo ye-sleeve ezinobukhulu obahlukeneyo bobukhulu kwangaphambili ukuze kukhethwe kwindibano.
(3) Indlela yokulungisa: ivalve ihlanganiswe ngendlela yokulungisa. Amalungu angacutshungulwa ngokuchaneka kwezoqoqosho. Ngethuba lokuhlanganisana, ubungakanani bohlengahlengiso oluthile kunye nomphumo wembuyekezo unokulungiswa ukufezekisa injongo yendibano echaziweyo. Ngokomzekelo, isango levalve yesango kunye nomzimba wevalve, ngenxa yokuba iindleko zokutshintshiselana kweemfuno zokutshintshiselana ziphezulu kakhulu, abaninzi abavelisi basebenzisa iteknoloji yendlela yokulungisa. Oko kukuthi, xa ulawula ubungakanani bokuvulwa kwesango lokutywinwa kobuso ekusileni ngasemva, ipleyiti kufuneka ihambelane nobukhulu bokuvula ubuso bokutywinwa bomzimba wevalve ukwenzela ukufezekisa iimfuno zokutywinwa. Le ndlela yongezwa kwinkqubo yepleyiti, kodwa ** yenza lula iimfuno zokuchaneka kwe-dimensional yenkqubo yokucubungula kwangaphambili, inkqubo yeplate yomntu onobuchule, ngokubanzi ayiyi kuchaphazela ukusebenza kwemveliso. Inkqubo yokudityaniswa kwevalve: Ivalve idityaniswe ngokukodwa kwindawo esisigxina. Ukuhlanganiswa kwamacandelo kunye namacandelo e-valve kuqhutyelwa kwi-workshop yendibano, kwaye zonke iinxalenye ezifunekayo kunye namacandelo zithunyelwa kwindawo yokusebenza yendibano. Ngokuqhelekileyo iinxalenye indibano kunye nendibano iyonke ukwahlula ukuba mangaphi na amaqela abasebenzi ngexesha elinye, nto leyo engafinyeleli nje kuphela umjikelo wendibano, kodwa iququzelele ukusetyenziswa kwezona zixhobo zibalaseleyo zokuhlanganisa, iimfuno zenqanaba lobugcisa babasebenzi nazo ziphantsi.
Abanye abavelisi bamanye amazwe okanye iivalvu zomgangatho ophezulu wetekhnoloji zikwasebenzisa umgca wokuxhoma wendibano okanye imowudi yetafile ejikelezayo:
(1) Umsebenzi wokulungiselela phambi kwendibano: Amalungu evalve aya kususa i-burr eyenziwe ngomatshini kunye nentsalela ye-welding, icoce kwaye inqumle ukupakisha kunye ne-gasket phambi kokudibanisa.
(2) ukucoca iindawo zevalve: njengofakelo lolawulo lombhobho wolwelo kwivalve, umngxuma ongaphakathi kufuneka ucoceke. Ngokukodwa amandla enyukliya, amayeza, iivalvu zeshishini lokutya, ukuze kuqinisekiswe ukucoceka okuphakathi kwaye kuthintelwe usulelo oluphakathi, iimfuno zococeko lomngxunya wevalve zibukhali ngakumbi. Coca Amacandelo e-valve PHAMBI KOKUHLANGABEZANA UKUSUSA INGXEKO, I-OLI EZISELELEYO, EZINGQALAYO, I-COOLANT NE-BURR, i-WELDING SLAG KUNYE NOBUCHULE KWI-PARS. Ukucocwa kweValve KUQHELEKILEYO NGENXA yokutshiza AMANZI okanye AMANZI atshisayo nge-ALKALI (KEROSENE ingasetyenziselwa ukucoca) okanye kwi-ultrasonic cleaner. Amalungu kufuneka ahlanjululwe emva kokusila kunye nokupholisha, kwaye ukucoca ngokuqhelekileyo ukuxubha indawo yokutywina ngepetroli, kwaye emva koko uvuthulule ngomoya ocinezelweyo kwaye usule ucoceko ngelaphu.
(3) ukupakisha kunye nokulungiswa kwe-gasket: ukupakishwa kwegraphite kusetyenziswe ngokubanzi ngenxa yeenzuzo zokuxhathisa ukubola, ukutywinwa kakuhle kunye ne-coefficient encinci ye-friction. Isigcwalisi kunye ne-gasket ukuthintela ukuvuza kweendaba ngesiqu kunye nesigqubuthelo kunye nobuso obudibeneyo beflange. Ezi zixhobo kufuneka zilungiselelwe ukusika kunye nokuphathwa ngaphambi kokuhlanganiswa kwevalve.
(4) I-valve ye-valve: ivalve idla ngokusekwe kumzimba wevalvu njengeenxalenye zesalathiso ngokomyalelo kunye nendlela echazwe yinkqubo yokudibanisa. Ngaphambi kokuhlanganisana, iinxalenye neenxalenye zifanele zihlolisiswe kwakhona ukuze kuthintelwe iinxalenye ezingatshitshwanga nezingahlambulukanga ukuba zingene kwindibano yokugqibela. Kwinkqubo yokuhlanganisa, iinxalenye kufuneka ziphathwe ngononophelo ukuphepha ukunkqonkqoza kunye nokukrwela abasebenzi abalungisayo. Iindawo ezisebenzayo zevalve (ezifana nesiqu sevalve, ukuthwala, njl. njl.) kufuneka zigqunywe ngebhotolo yeshishini. I-flange yesivalo sevalve kunye nomzimba wevalve udityaniswe neebholiti. Xa i-bolts yokuqinisa, impendulo ithi, idibeneyo, ngokuphindaphindiweyo kwaye iqiniswe ngokulinganayo. Kungenjalo, umphezulu odityanisiweyo womzimba wevalvu kunye nesigqubuthelo sevalvu iya kuvelisa ukuvuza kwevalvu yokulawula ukuhamba ngenxa yamandla angalinganiyo ayijikelezileyo. Isiphatho esisetyenziselwa ukuqinisa akufunekanga sibe side kakhulu ukunqanda ukulayishwa kwangaphambili kuchaphazele amandla ebholithi. Kwi-VALVES EZINEMIFUNO EZIQHELEKILEYO ZOKUQALA, izibambo zetorque ziya kusetyenziswa ukuqinisa iibholithi ngokweemfuno zetorque ezichaziweyo. Emva kokuhlanganiswa, indlela yokulawula kufuneka ijikelezwe ukuze kuhlolwe ukuba umsebenzi wokuvula i-valve kunye neendawo zokuvala zihamba kunye nokuba kukho indawo yokuvala. Ikhava ye-VALVE, inkxaso kunye nezinye iindawo zesalathiso sesixhobo ngokuhambelana neemfuno zemizobo, zonke iiphononongo ziye zadlula i-valve zinokuvavanywa.
Indlela yokudibanisa i-actuator yombane kunye ne-valve I-actuator yombane ihambelana kakhulu ne-valve, esetyenziswa kwinkqubo yokulawula ngokuzenzekelayo. Kukho iintlobo ezininzi zee-actuator zombane, ezahlukileyo kwindlela yokusebenza.
