Solenoid valve kelen min bɛ kɔrɔsi kuran fɛ, i n’a fɔ a tɔgɔ b’a jira cogo min na, o bɛ ni bobine kelen dɔrɔn ye. Ni fanga donna a la, a bɛna Changé ka don cogo wɛrɛ la. Ni fanga tigɛra, a bɛ segin a cogo kɔrɔ la a yɛrɛma. Nin baarakɛcogo in jiralen bɛ ja 5 kɔnɔ. Ni bobinew danfaralenw ka fanga cogoyaw kɔlɔsili ye, a bɛ se ka switch caman sɔrɔ ani ka a cogoya kɔrɔ mara hali bi fanga-bɔli kɔfɛ, i n’a fɔ a jiralen bɛ cogo min na ja 6. O baarakɛcogo danfara bɛ u ka sugandili danfaralenw ɲɛfɔ tigitigi baarakɛcogo ɲumanw na.

Ni a ka kan ka sisan cogoya mara kuran tiɲɛni kɔfɛ, solenoid valve fila-fila bɛ bɛn.
V. Danfara ni baarakɛcogo minnu bɛ solenoid valves pilotiw ni solenoid valves directs cɛ .
Solenoid valves suguyaw la, piloti-baara ni a kɛcogo tilennen ye suguya fila ye minnu bɛ sɔrɔ tuma caman na. U tɛ kelen ye baarakɛcogo sariyaw ni baarakɛcogo cogoyaw la. Piloti bɛ baara kɛ ni solenoid valves ye gazi ni jilama cɛ ka tɛmɛ piloti dingɛw fɛ, ka sɔrɔ ka solenoid valves kɛ ka ɲɛsin degun danfara ma walasa ka valve core lamagacogo kɔlɔsi. O danfara in b’a to solenoid valve suguya fila kelen-kelen bɛɛ bɛ nafa sɔrɔ n’u bɛ jaabi di izini ɲinini suguya wɛrɛw ma. Misali la, ko dɔw la minnu bɛ jaabi teliya ani ka sɛgɛsɛgɛli kɛ kosɛbɛ, solenoid valves directe bɛ se ka kɛ ka ɲɛ. Ni ko dɔw bɛ kɛ, ni a ka kan ka kɛ ni fanga dɔgɔyali ye ani fanga dɔgɔyali ye, pilotiw bɛ baara kɛ ni solenoid valves ye.
Solenoid valves direct-acting structurel (dafalenw) jɔcogo ka nɔgɔn kosɛbɛ. U ka baarakɛcogo bɛ tali Kɛ kɛrɛnkɛrɛnnenya la kuran-magnetiki fanga la walasa ka valve core (datugulan) Lawuli k’a Kɛ. Nka, nin dilan in fana bɛ ni dɛsɛba fila ye. A fɔlɔ, k’a sababu Kɛ kuran-magnetiki fanga ɲininiba ye, kuran-magnet bobine hakɛ bɛ bonya ka Kɛɲɛ n’o ye, o min bɛ Nà ni fanga caman sɔrɔli ye. Filanan, solenoid valves direct-acting bɛ sɛgɛn ka ɲɛsin degun ma. Ni tansiyɔn tɛmɛna dan dɔ kan (a ka c’a la, 0,7mpa ka ca ni 0,7MPa ye), solenoid valves caman bɛ se ka baara kɛ ka ɲɛ. O bɛ sɔrɔ kɛrɛnkɛrɛnnenya la degunba min bɛ baara kɛ valve core kan, o bɛ gɛlɛya sɔrɔ kuran fanga la ka valve core bila ka baara kɛ. O bɛɛ n’a ta, solenoid valves directe (solenoid valves) fana nafa bɛ u la: u jɔcogo nɔgɔman, u sɔngɔ ka nɔgɔn ani u ka dɛsɛ hakɛ ka dɔgɔ.
2. Solenoid valve min bɛ baara kɛ ni piloti ye, o dilannen don ni hakilitigiya ye. A bɛ laadala kuran-magnetiki fanga-taama bila ani o nɔ na, a bɛ fiɲɛ tansiyɔn Kɛ walasa ka valve core (valve core) Lawuli ka wale Kɛ. Solenoid valves minnu cɛmancɛ ka ca ni 4mm ye, a ka c’a la, u bɛ kɛ pilote valve ye ani valve principal. Solenoid valve (solenoid valve) kɛlen kɔ, pilote (piloti) bɛ da wuli ani k’a kunnafoni a ka bɔli taamasiyɛn fɛ. A ka kan ka kɔlɔsi ko tiɲɛ na, valve kunba ye pneumatic control valve ye, wa a baara bɛ fiɲɛ sɔrɔyɔrɔ fila ka baara kɛcogo ɲɛnabɔ: kelen ye valve fiɲɛ sɔrɔyɔrɔba ye, ani tɔ kelen ye pilote valve fiɲɛ sɔrɔyɔrɔ ye.
Ni fiɲɛ sɔrɔyɔrɔba bɛ fiɲɛ di piloti ka valve ma ka tɛmɛ solenoid valve kɔnɔna fiɲɛ fɛ, o dilan bɛ wele ko kɔnɔna piloti suguya. Ni piloti ka valve bɛ sɔrɔ ni gazi ye ka bɔ sɔrɔyɔrɔ la min tɛ gazi sɔrɔyɔrɔba la, a bɛ wele ko kɛnɛma piloti suguya. Jaa 8 kɔnɔ, numan fɛ, a bɛ misali jira kɛnɛma piloti-baarakɛ-solenoid valve la, k’a sɔrɔ kinin fɛ bɛ misali jira solenoid valve kɔnɔ min bɛ baara kɛ ni piloti ye.
Farikolo-ɲɛnajɛ min bɛ kɔnɔna-plosi ni kɛnɛma-yɔrɔ cɛ, o jiralen bɛ ja nata la.
Nin solenoid valves suguya fila, n’olu ye kɔnɔna piloti ni kɛnɛma piloti ye, olu bɛ to ka ɲɔgɔn sɔrɔ o cogo kelen na. A ka c’a la, kɔnɔna piloti bɛ se ka ko fanba mago ɲɛ kaban. Nka, ko kɛrɛnkɛrɛnnen dɔw la, kɛnɛma ɲɛmɔgɔya bɛ kɛ wajibi ye ka tɛmɛn fɔlɔ kan. Misali la, ni gazi sɔrɔyɔrɔ tansiyɔn bɛ wuli ka bɔ 0,2MPa duguma, walima ni a bɛ yɔrɔ la min bɛ kɛ ni vacuum ye, bawo gazi bɔyɔrɔ gazi bɔyɔrɔ tɛ se ka tila ni valve kunba ta ye, n’o tɛ, a bɛ se ka kɛ sababu ye ka valve kunba da wuli. Nin yɔrɔ in na, fiɲɛbɔyɔrɔ yɛrɛmahɔrɔnyalen min ka tansiyɔn tɛmɛna 0,2MPa kan, o de ka kan ka kɛ walasa ka pilote valve fanga di. Ka fara o kan, ni fiɲɛ dondaw ni bɔdaw cɛ degun danfara ka bon, walima ni fiɲɛbɔyɔrɔ tansiyɔnba tɛmɛna 1MPa kan, kɔnɔna na, a bɛ se ka kɛ ko a ka kan ka dɔ fara a jɔcogo hakɛ kan, a kɛtɔ ka fiɲɛbɔyɔrɔ tansiyɔn doni tilennen na sumanmugu kɔnɔna na. Kɛnɛma piloti bɛ gɛlɛya in ɲɛnabɔ ni gazi sira kelen donli ye piloti port kɔnɔ k’a sɔrɔ a ma kɛ ko kuran-magnetiki-minɛn dɔ farala a kan; Fiɲɛbɔlan dɔrɔn de ka kan ka fara a kan.
Kuncɛli la, solenoid valves minnu bɛ baara kɛ ni pilotiw ye, olu nafa ye kuran-magnetiki kunkolo misɛnninw ye ani fanga dɔgɔyali. A bɛ diya ɲɛnajɛko siratigɛ la wa a bɛ installation space kisi.

Min nafa ka bon kosɛbɛ, o ye ko funteni dɔgɔyali kosɔn, bobine ka teli ka jeni ka ban, wa a bɛ se ka fanga sɔrɔ a kan waati jan kɔnɔ. O nafa ka bon kosɛbɛ baarakɛcogo la min bɛ se ka kɛ. Misali la, solenoid valves dɔw fanga dɔgɔyara ka se 0,1W ma, o bɛ se ka kɛ sababu ye ka fanga sɔrɔ tuma bɛɛ k’a sɔrɔ a ma sumaya kojugu. Solenoid valves direct-acting fanga hakɛ ye 4-20W ye, fanga ni waati ka surun. Ka fara o kan, fanga bɛ to ka kɛ fɛn ye min bɛ se ka kɛ farati ye. O la, ko minnu na kuran sɔrɔli waati janw na walima ni a ka kan ka kɛ ni frequences caman ye, piloti-operated solenoid valves bɛ kɛ sugandili ɲuman ye. Tiɲɛ na, solenoid valve minnu bɛ kɛ ka caya bi, olu fanba ye piloti-baarakɛcogo ta. Solenoid valves (sɔgɔsɔgɔninjɛ) minnu bɛ ji dɔrɔn de tɛmɛ, olu dɔw bɛ hali bi u hakɛ dɔ jira.
