Ni ɲɔgɔndan fɛɛrɛ sugandili bɛ kɛ butterfly valve ni pipeline walima minɛnw cɛ, o bɛ bɛn walima ni a tɛ tiɲɛ ye, o bɛna nɔ bila pipeline valve bolicogo, a jigincogo, a jigincogo ani a bɔncogo la. Valve sirili fɛɛrɛ minnu bɛ kɛ tuma caman na, olu ye : flange ɲɔgɔndan, wafer ɲɔgɔndan, butt welding ɲɔgɔndan, threaded connection, ferrule connection, clamp connection, self-sealing connection ani jɛgɛncogo wɛrɛw.
A. Flange ka ɲɔgɔndan
Flange jɛgɛn ye aflanged butterfly valve ye min bɛ wele ko butterfly valveni flansɛw ye valve farikolo dakun fila bɛɛ la, minnu bɛ bɛn flansɛw ma pibiliki kan, wa u bɛ sigi pibiliki kɔnɔ ni flansɛw sirili ye. Flange connection ye jɛgɛncogo ye min bɛ kɛ ka caya valvew kɔnɔ. Flansɛw bɛ tila ka kɛ yɔrɔ ye min bɛ wele ko convex surface (RF), surface flat (FF), convexe ani concave surface (MF), wdfl.
B. Wafer ka ɲɔgɔndan
Valve bɛ sigi flansɛ fila cɛmancɛ la, ani valve farikolo kawafer butterfly ka bɔgɔdagaa ka c’a la, jɔyɔrɔ dingɛ bɛ a la walasa ka a sigili ni a bilali nɔgɔya.
C. Solder ka ɲɔgɔndan
(1) Butt welding connection: Valve farikolo kun fila bɛɛ bɛ baara kɛ ka kɛ butt welding grooves ye ka kɛɲɛ ni butt welding requirements ye, minnu bɛ bɛn pipeline welding grooves ma, wa u bɛ siri pipeline kan welding fɛ.
(2) Socket welding connection: Valve farikolo dakun fila bɛɛ bɛ baara kɛ ka kɛɲɛ ni socket welding wajibiyalenw ye, wa u bɛ siri ni pipeline ye socket welding fɛ.
D. Jɛɲɔgɔnya min bɛ kɛ ni jiri ye
Jɛɲɔgɔnya minnu bɛ kɛ ni jiri ye, olu ye ɲɔgɔndan fɛɛrɛ nɔgɔman ye, wa a ka ca a la, u bɛ kɛ ni jirisun misɛnninw ye. Valve farikolo bɛ baara kɛ ka kɛɲɛ ni jiri kelen-kelen bɛɛ sariya ye, wa kɔnɔna jiri ni kɛnɛma jiri suguya fila bɛ yen. A bɛ bɛn jiri ma min bɛ pipe kan. Jɛɲɔgɔnya minnu bɛ Kɛ ni jiri ye, olu suguya fla bɛ yen:
(1) Sigili tilennen: Kɔnɔna ni kɛnɛma jiriw bɛ sigili jɔyɔrɔ tilennen na. Walasa ka a jira ko ɲɔgɔndan kana bɔn, a ka ca a la, a bɛ fa ni plɔmu tulu ye, ni jiri kansɛri ani PTFE ka fɛnɲɛnamafagalan kasɛti ye; minnu cɛma, PTFE ka fɛnɲɛnamafagalan kasɛti bɛ baara kɛ kosɛbɛ; nin fɛn in bɛ se ka sɔgɔsɔgɔ ka ɲɛ ani a bɛ se ka datugu cogo ɲuman na. A baara ka nɔgɔn ani a marali. Ni a bɛ tigɛ, a bɛ se ka bɔ pewu barisa a ye filimu ye min tɛ nɔrɔ, o ka fisa kosɛbɛ ni plɔmu tulu ni jiri kansɛri ye.
(2) Dasirili siratigɛ la: jiri sirili fanga bɛ taa gazi la o pankurun fila ni ɲɔgɔn cɛ, walasa gazi ka se ka sigili jɔyɔrɔ ta.
E. ferrule ka ɲɔgɔndan
Ferrule jɛɲɔgɔnya in yiriwara n ka jamana kɔnɔ dɔrɔn nin san laban ninnu na. A jɛgɛncogo ni a datugucogo sariya ye ko ni nut sirilen don, ferrule bɛ degun, fo ferrule da bɛ kin ka don pipe kɛnɛma kogo la, ka ferrule kɛnɛma cone surface siri joint la degun kɔnɔ. Farikolo kɔnɔna bɛ ɲɔgɔn sɔrɔ kosɛbɛ ni a yɔrɔ nɔgɔlen ye, o la, ji bɔli bɛ se ka bali ni dannaya ye. I n’a fɔ minɛnw ka bɔlɔnw. O jɛɲɔgɔnya sugu in nafa ye :
(1) A bonya ka dɔgɔ, a girinya ka nɔgɔn, a jɔcogo ka nɔgɔn, a tigɛcogo ni a lajɛcogo nɔgɔn;
(2) Jɛɲɔgɔnya fanga barikama, baarakɛcogo caman, degunba kɛlɛli (1000 kg/cm 2 ), funteni caman (650 ° C) ani sɔgɔsɔgɔ ni yɛrɛyɛrɛ;
(3) Fɛn suguya caman bɛ se ka sugandi, minnu bɛnnen don ka sɔgɔsɔgɔninjɛ kɛlɛ;
(4) Wajibiya minnu bɛ kɛ walasa ka masinw kɛ ka ɲɛ, olu man bon;
(5) A bɛnnen don ka sigi yɔrɔ janw na.
Sisan, ferrule jɛgɛncogo kɛra fɛnɲɛnamafagalan dɔw la minnu janya ka dɔgɔn n ka jamana kɔnɔ.
F. Jɛɲɔgɔnya min bɛ kɛ ni jirisunw ye
Nin ye ɲɔgɔndan teliya fɛɛrɛ ye, a mago bɛ bololanɛgɛ fila dɔrɔn de la, waa laban na, butterfly valve min bɛ sɔgɔsɔgɔbɛ bɛn tansiyɔn dɔgɔyali mabutterfly valvew (wuluwuluw).minnu ka teli ka tigɛtigɛ. i n’a fɔ saniyalanw.
G. Kɔnɔna yɛrɛ-gɛlɛya jɛɲɔgɔnya
Sanfɛla jɛgɛncogo bɛɛ bɛ kɛnɛma fanga kɛ walasa ka fɛnɲɛnamafagalan degun kunbɛn walasa ka se ka sigili sɔrɔ. Ninnu bɛ yɛrɛ-gɛlɛya jɛgɛncogo ɲɛfɔ ni degun cɛmancɛ ye.
A datugulan bɛ Sìgi kɔnɔna na, wa a bɛ kɛrɛ dɔ Kɛ ni kɛrɛ ye min ɲɛsinnen bɛ fɛnɲɛnamafagalan ma. Fɛnɲɛnɛma in degun bɛ taa kɔnɔna na, o kɔfɛ ka taa sigilan bololanɛgɛ la. Kɔnɔ dɔ ka konnɛgɛ sanfɛ, yɔrɔ fanga fila bɛ bɔ, kelen ni The center line of the valve body is parallel to the outside, ani tɔ kelen bɛ digi valve farikolo kɔnɔna kogo kan. Fanga laban in ye yɛrɛ-gɛlɛya fanga ye. Ni degun cɛmancɛ ka bon, yɛrɛ-gɛlɛya fanga bɛ bonya. O la, nin jɛgɛncogo in bɛnnen don tansiyɔnba wulilanw ma.
Ni i y’a suma ni flansɛ ɲɔgɔndan ye, a bɛ fɛn caman ni baarakɛlaw kisi, nka a bɛ preload dɔ fana de wajibiya, walasa a ka se ka baara kɛ ni a ye ni dannaya ye ni degun min bɛ valve kɔnɔ, o ma caya. Valve minnu dilannen don ni yɛrɛsirili sariya ye, a ka c’a la, olu ye degunba ye.
Valve connection suguya caman bɛ yen, misali la, valve misɛnnin dɔw minnu man kan ka bɔ, olu bɛ welda ni pipew ye; fɛn dɔw minnu tɛ nɛgɛ ye, olu bɛ ɲɔgɔn sɔrɔ ni sosɛtiw ye ani o ɲɔgɔnnaw. Valve talikɛlaw ka kan ka furakɛ ka kɛɲɛ ni ko kɛrɛnkɛrɛnnen ye.
Nɔti:
(1) Jɛɲɔgɔnya fɛɛrɛw bɛɛ ka kan ka ɲɛsin sariyaw ma minnu bɛ bɛn o ma ani ka sariyaw ɲɛfɔ walasa ka valve sugandilen bali ka sigi.
(2) A ka c’a la, pibiliki ni valve min janya ka bon, olu bɛ ɲɔgɔn cɛ ni flange ye, ani pipeline ni valve min janya ka dɔgɔ, olu bɛ ɲɔgɔn cɛ ni jiri ye.
