UMGANGATHO WE-DBB Plug Valve

Iimpawu zoYilo lwe-DBB Plug Valve:

1. Isakhiwo somzimba seValve

Umzimba wevalvu ye-DBB Plug Valve yethu uquka umzimba wevalvu, i-valve core, i-valve disc (efakwe kwi-main sealing ring), i-end cover, i-chassis, ukupakisha kunye nezinye izinto eziphambili. I-valve core kunye ne-disc zingundoqo wenxalenye yomzimba wevalvu. I-valve core iqinile emzimbeni wevalvu ngee-trunnion eziphezulu nezisezantsi, ukuvulwa komjelo we-flow kuphakathi, kwaye amacala amabini amile okwe-wedge. I-wedge face mill inee-dovetail guide rails eziqhotyoshelwe kwiidiski ezimbini kumacala omabini. I-disc yeyona nto iphambili yokutywina kwaye inomphezulu we-cylindrical. Ukuchaneka kwe-Class B hard seal kunokufezekiswa. Umphezulu we-cylindrical ugoqwe ngesangqa se-groove, kwaye i-main sealing ring igxilwe ngokusisigxina nge-fluorine rubber okanye i-nitrile rubber, njl. ngokubumba kunye ne-vulcanization, edlala indima yokutywina okuqinileyo kunye nokutywina okuthambileyo xa ivalvu ivaliwe.

2. Ulwakhiwo lwe-manipulator

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.

3. Vala inkqubo.

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.

4. Umsebenzi we-DBB okanye we-DIB

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.
