Ivalvu yePlug yeDBB yeTywina eliBini eliNyulayo i-Orbit eNyulayo kabini
✧ Inkcazo
Umzimba wevalvu yeTwin Seal DBB Plug Valve Orbit Dual Expanding General Valve yethu uquka umzimba wevalvu, iplagi yevalvu, idiski yevalvu (efakwe kwiringi yokutywina ephambili), isigqubuthelo sokugqibela, itshasi, ukupakisha kunye nezinye izinto eziphambili. Umongo wevalvu kunye nediski zingundoqo wenxalenye yomzimba wevalvu. Iplagi yevalvu iqiniswe emzimbeni wevalvu ngee-trunnions eziphezulu nezisezantsi, ukuvulwa komjelo wendlela kuphakathi, kwaye amacala amabini amile okwe-wedge. I-wedge face mill inee-dovetail guide rails eziqhotyoshelwe kwiidiski ezimbini kumacala omabini. Idiski yeyona nto iphambili yokutywina kwaye inomphezulu we-cylindrical. Ukuchaneka kwe-Class B hard seal kunokufezekiswa. Umphezulu we-cylindrical ugoqwe ngesangqa se-groove, kwaye iringi yokutywina ephambili ifakwa ngokusisigxina ngerabha ye-fluorine okanye irabha ye-nitrile, njl. ngokubumba kunye ne-vulcanization, edlala indima yokutywina okuqinileyo kunye nokutywina okuthambileyo xa ivalvu ivaliwe.
I-DBB Plug Valve (i-valve ye-double block kunye ne-bleed plug) ekwabizwa ngokuba yi-GENERAL VALVE, i-Twin Seal plug valve. Oku kuguga rhoqo ngokusebenzisa iziliphu ezimbini zokuhlala ezifakwe ngokwazo kwi-plug enciphileyo yi-dovetails, ezirhoxa ngomatshini kumphezulu wesihlalo ngaphambi kokuba zijikeleze. Oku kubonelela nge-dual seal engqinisisekayo engenamaqamza ngaphandle kokukrazulwa kwe-seal.
I-manipulator yenziwe ikakhulu ziimpawu, ivili lesandla, ii-spindle bushings, ii-ball pin, ii-brackets kunye nezinye izinto, ezinamathele kwisiciko sokugqibela kwaye ziqhagamshelwe ngentonga ye-spool ngee-connecting pin. Icandelo le-manipulator liyi-actuator yesenzo. Vala i-valve ukusuka kwindawo evulekileyo, jika ivili lesandla ngokwewotshi, i-valve core ijikeleza i-90° kuqala, kwaye iqhube i-valve disc ukuba ijikeleze ukuya kwindawo ye-valve body flow channel. Emva koko i-valve core ihamba ngomgca othe tye, iqhube i-valve disc ukuba yande nge-radially kwaye isondele eludongeni lwangaphakathi lwe-valve de i-seal ethambileyo icinezelwe kwi-groove, ukuze umphezulu we-valve disc uqhagamshelane nodonga lwangaphakathi lwe-valve.
Vula ivalvu usuka kwindawo evaliweyo, jika ivili lesandla lijikeleze ngecala lewotshi, i-valve core iqale ihambe ngqo phezulu, ize ijikeleze i-90° emva kokufikelela kwindawo ethile, ukuze ivalvu ibe kwimeko yokuqhuba.
✧ Iimpawu zeTwin Seal DBB Plug Valve Orbit Dual Expanding General Valve
1. Ngexesha lenkqubo yokutshintsha ivalvu, umphezulu wokutywina umzimba wevalvu awunanxibelelwano nomphezulu wokutywina ipleyiti etyibilikayo, ngoko ke umphezulu wokutywina awunakungqubana, ukuguguleka, ubomi benkonzo ende bevalvu kunye ne-torque encinci yokutshintsha;
2. Xa ivalvu ilungisiwe, akufuneki ukuba uyisuse ivalvu kumbhobho, susa nje isigqubuthelo esisezantsi sevalvu uze ufake esinye isilayidi, esilungele kakhulu ukulungiswa;
3. Umzimba wevalvu kunye ne-cock ziyancitshiswa, nto leyo enokunciphisa iindleko;
4. Umngxuma ongaphakathi womzimba wevalvu ugqunywe nge-chromium eqinileyo, kwaye indawo yokutywina iqinile kwaye igudile;
5. Itywina le-elastic kwislayidi lenziwe ngerabha ye-fluorine kwaye libunjwe kwi-groove kumphezulu wesilayidi. Itywina lesinyithi ukuya kwisinyithi elinomsebenzi wokukhusela umlilo lisetyenziswa njengenkxaso yesitywina se-elastic;
6. Ivalvu inesixhobo sokukhupha ngokuzenzekelayo (ukhetho), esithintela ukunyuka koxinzelelo okungaqhelekanga kwigumbi levalvu kwaye sijonga impembelelo yevalvu emva kokuba ivalvu ivaliwe ngokupheleleyo;
7. Isalathisi sokutshintsha ivalvu sihambelana nendawo yokutshintsha kwaye sinokubonisa ngokuchanekileyo imeko yokutshintsha kwevalvu.
