Flange ea valve ea serurubele ea Triple offset ke eng?
Valo ea serurubele e sa tloaelehang e meraro,e tsejoang hape e levalve ea serurubele e habeli, ke mofuta o mong oa li-valve tsa serurubele tse sebetsang hantle, tse etselitsoeng maemo a ts'ebetso a khatello e phahameng, mocheso o phahameng, le maqhubu a phahameng a ho buleha le ho koala.
Valve ea serurubele e nang le rabara e kopantseng, e nang le moralo o hōlileng le theknoloji ea tlhahiso, e tšepahala ka boleng le litšenyehelo tse mosa. Empa bakeng sa lits'ebetso tse matla joalo ka mocheso o phahameng kapa maqhubu a holimo a ho bula le ho koala, ha hoa lumelloa ho sebelisa li-valve tsa serurubele tsa setulo se bonolo. Kahoo li-valve tsa serurubele tse tiileng, setulo sa tšepe kapa setulo sa ceramic, tse etselitsoeng mocheso o phahameng, khatello e phahameng kapa maqhubu a phahameng a ho koala ho bulehileng, li ile tsa sebelisoa, empa ts'ebetso ea ho koala ea valve ea serurubele ea setso e thata e ne e lula e le taba e kholo.
Valo ea serurubele e sa tloaelehang e meraro(e tsejoang hape e le valve ea serurubele e nang le li-triple offset) e qapiloe tabeng ena.

Likarolo tse ka sehloohong tsa flange ea valve ea serurubele ea Triple offset
- Sebaka se shebaneng le letheba la flange se netefatsa hore nate ea bolting le planarity ea washer lia tšoana, se eketsa ts'epo le polokeho ea manonyeletso.
- Mehele ea tiiso ea duplex le graphite e ka nkeloang sebaka habonolo.
- Shaft e matlafalitsoeng haholo ea karolo e le 'ngoe e etselitsoeng ho fetisetsa/ho boloka torque ka katleho.
- Litšireletso tsa graphite tse lohiloeng li thibela ho kena-kenana ha mobu, li netefatsa hore torque e sebetsa kamehla le hore li-valve lia sebetsa.
- Ho paka ha gland ea likarolo tse peli le ho paka ha graphite ho fokotsa kotsi ea ho ntša mosi o tsoang kantle.
- Kgokelo e tiileng ya shaft-to-disc bakeng sa botsitso bo phahameng ba shaft.
- Li-gasket tsa maqeba a spiral, li-seal le masale a ho paka li ka nkeloa sebaka ntle le lisebelisoa tse khethehileng.
- Li-bearing tse boima li mamella meroalo e phahameng ea khatello le ho tsofala.
- Ho sebetsana le kotsi ea ho ntša mosi ka hare le ka ntle ho latela maemo a machaba.
