Kenyelletso ea li-valve tsa Ball

Li-valve tsa bolo

Balofo ea Ball ke valve ea "quarter-turn rotational movement" e sebelisang disk e bōpehileng joaloka bolo ho emisa kapa ho qala ho phalla. Haeba valve e butsoe, bolo e potoloha ho ea moo lesoba le kenang ka har'a bolo le lumellanang le ho kena ha 'mele oa valve le ho tsoa. Haeba valve e koetsoe, bolo e pota-potiloe e le hore lesoba le pota-potile ho phallo ea phallo ea 'mele oa valve' me phallo e emisitsoe.

Mefuta ea li-valve tsa Ball

Li-valve tsa bolo li fumaneha ka mefuta e meraro: boema-kepe bo felletseng, boema-kepe ba venturi le boema-kepe bo fokotsehileng. Sephahla se tletseng koung se na le bophara ba ka hare bo lekanang le bophara bo ka hare ba phala. Liphetolelo tsa Venturi le li-port tse fokotsehileng hangata li nyane ka boholo ba phala e le 'ngoe ho feta boholo ba mohala.

Li-valve tsa bolo li entsoe ka litlhophiso tse fapaneng tsa 'mele mme tse atileng haholo ke:

• Li-valve tsa ho kena ka holimo li lumella ho fihlella ho ba ka hare ho li-valve bakeng sa tlhokomelo ka ho tlosa sekoahelo sa valve Bonnet. Ha ho hlokahale hore ho tlosoe valve ho tloha tsamaisong ea phala.
• Li-valve tsa 'mele tse arohaneng li na le likarolo tse peli, moo karolo e' ngoe e leng nyane ho feta e 'ngoe. bolo e kenngoa karolong e kholo ea 'mele,' me karolo e nyenyane ea 'mele e bokelloa ka ho hokahanya ka bolt.

Lipheletso tsa valve li fumaneha joalo ka welding butt, welding socket, flanged, threaded le tse ling.

Lisebelisoa - Moralo - Bonnet

Lisebelisoa

Hangata libolo li entsoe ka metallics tse 'maloa, ha litulo li tsoa linthong tse bonolo tse kang Teflon®, Neoprene, le metsoako ea lisebelisoa tsena. Tšebeliso ea thepa ea litulo tse bonolo e fana ka bokhoni bo babatsehang ba ho tiisa. Bothata ba lisebelisoa tsa setulo se bonolo (lisebelisoa tsa elastomeric) ke hore ha li khone ho sebelisoa ka mekhoa e phahameng ea mocheso.

Ka mohlala, litulo tsa polymer tse nang le fluorinated li ka sebelisoa bakeng sa mocheso oa tšebeletso ho tloha −200° (le ho feta) ho ea ho 230°C le ho feta, ha litulo tsa graphite li ka sebelisoa bakeng sa mocheso ho tloha ho ?° ho ea ho 500°C le ho feta.

Moralo oa stem

The stem e valve ea Ball ha e khomaretsoe bolo. Hangata e na le karolo e khutlonnetsepa holim'a bolo, 'me e lekana le sekotjana se sehiloeng ka har'a bolo. Ho atolosoa ho lumella ho potoloha ha bolo ha valve e buloa kapa e koaloa.

Bonnet ea valve ea bolo

Bonnet ea valve ea Ball e tlamahane le 'mele, e tšoarang kopano ea stem le bolo sebakeng sa eona. Tokiso ea Bonnet e lumella khatello ea ho paka, e fanang ka tiiso ea stem. Lisebelisoa tsa ho paka bakeng sa li-valve tsa Ball hangata ke Teflon® kapa Teflon-filled kapa O-rings sebakeng sa ho paka.

Lisebelisoa tsa li-valve tsa bolo

Tse latelang ke tse ling tsa lits'ebetso tse tloaelehileng tsa li-valve tsa Ball:

• Lisebelisoa tsa moea, khase, le metsi
• Lits'oants'o le lifensetere tsa metsi, tsa gase le lits'ebeletso tse ling tsa mokelikeli
