Valve positioner i xitirhisiwa xosungula xa ti pneumatic actuators. Yitirhisiwa xikan’we na ti pneumatic actuators ku antswisa ku pakanisa ka ndzhawu ya ti valve xikan’we naku hlula mbuyelo wa stem friction xikan’we na matimba lawa yanga ringaniseriwangiki kusuka eka medium, kutiyisisa leswaku valve yi vekiwa kahle kuya hi swikombiso leswi humaka eka controller.

Xitirhisiwa xo veka xiyimo xi fanele ku tirhisiwa eka swiyimo leswi landzelaka:

Loko ntshikelelo wale xikarhi wuri e henhla naswona kuri na ku hambana lokukulu ka ntshikelelo.

Loko vukulu bya valve byi ri byikulu (DN > 100).

Eka ti valve to lawula ta mahiselo yale henhla kumbe yale hansi.

Loko kuri na xilaveko xo engetela rivilo ra actuation ra valve yo lawula.

Loko ku tirhisiwa swikombiso swa ntolovelo na ku tirha ti spring ranges letingariki ta standard (springs ehandle ka range ya 20-100KPa).

Loko yi tirhisiwa eka vulawuri bya xiteji.

Loko ku fikeleriwa xiendlo xa valve yo tlhelela endzhaku (xikombiso, ku cinca exikarhi ka leswi pfaleriweke hi moya na leswi pfuriweke hi moya).

Loko kuri na xilaveko xo cinca swihlawulekisi swa ku khuluka ka valve (positioner cam yinga lulamisiwa).

Loko kungari na spring actuator kumbe piston actuator naswona proportional action ya laveka.

Loko ku tirhisiwa ti pneumatic actuators leti nga na swikombiso swa gezi, ku fanele ku tirhisiwa xitirhisiwa xo veka valve ya gezi-moya.

Valve ya Solenoid: .

Loko sisiteme yi lava vulawuri bya nongonoko kumbe vulawuri bya on-off, ku tirhisiwa ti valve ta solenoid. Loko ku hlawuriwa valve ya solenoid, handle ko tekela enhlokweni mphakelo wa gezi ra AC kumbe DC, voltage, na frequency, ku fanele ku nyikiwa nyingiso eka vuxaka bya ntirho exikarhi ka valve ya solenoid na valve yo lawula. Yi nga ha va ya muxaka lowu pfulekeke hi ntolovelo kumbe lowu pfalekeke hi ntolovelo. Loko swilaveka ku engetela vuswikoti bya valve ya solenoid kuva ku hungutiwa nkarhi wo hlamula, ti valve timbirhi ta solenoid tinga tirhisiwa hiku fambisana kumbe valve ya solenoid yinga tirhisiwa tani hi pilot valve hiku hlanganisiwa na large-capacity pneumatic relay.

Relay ya moya: .

Pneumatic relay i power amplifier leyi kotaka ku hundzisela swikombiso swa pneumatic eka tindzhawu tale kule, leswi herisaka ku hlwela loku vangiwaka hi tiphayiphi to leha ta signal. Yitirhisiwa ngopfu exikarhi ka ti field transmitters na ti central control rooms ta switirhisiwa swo lawula, kumbe exikarhi ka ti controllers na ti field control valves. Nakambe yi ni ntirho wo kurisa kumbe ku hunguta swikombiso.

Muhundzuluxi: .

Swihundzuluxi swi avanyisiwile hi swihundzuluxi swa gezi ra moya na swihundzuluxi swa gezi-moya. Ntirho wa tona i ku hundzula exikarhi ka swikombiso swa moya ni swa gezi hi ku ya hi vuxaka byo karhi. Ti tirhisiwa ngopfu loko ku tirhisiwa ti pneumatic actuators letingana swikombiso swa gezi, ku hundzula swikombiso swa gezi swa 0-10mA kumbe 4-20mA kuya eka swikombiso swa 0-100KPa swa pneumatic kumbe vice versa, ku hundzuriwa swikombiso swa gezi swa 0-10mA kumbe 4-20mA.

Mulawuri wa Xisefo xa Moya:

Ti regulators ta air filter i switirhisiwa leswi tirhisiwaka eka switirhisiwa swa automation swa ti indasitiri. Ntirho wa tona lowukulu iku sefa naku basisa moya lowu tshikeleriweke kusuka eka ti air compressor naku tiyisisa ntshikelelo eka nhlayo leyi lavekaka. Tinga tirhisiwa tani hi swihlovo swa gasi na switirhisiwa swo tiyisisa ntshikelelo eka switirhisiwa swohambana hambana swa moya, ti valve ta solenoid, ti cylinders, switirhisiwa swo fafazela, na switirhisiwa leswintsongo swa moya.

Valve yo Tipfalela (Valve yo Khiya ya Xiyimo): .

Valve yo tipfalela i xitirhisiwa lexi tirhisiwaka ku hlayisa xiyimo xa valve. Loko valve yo lawula moya yi kuma ku tsandzeka eka mphakelo wa moya, xitirhisiwa lexi xi nga tsema xikombiso xa moya, xi hlayisa xikombiso xa ntshikelelo eka kamara ra diaphragm kumbe silindara eka xiyimo xa le mahlweninyana ka ku tsandzeka. Leswi switiyisisa leswaku ndzhawu ya valve yi hlayisiwa eka xiyimo xale mahlweni ka ku tsandzeka, leswi tirhelaka xikongomelo xaku pfala ndzhawu.

Xihundzisi xa Xiyimo xa Valve:

Loko valve yo lawula yiri kule na kamara ro lawula naswona swilaveka kutiva kahle ndzhawu ya valve handle ko ya ensin’wini, kufanele ku vekiwa transmitter ya xiyimo xa valve. Yi hundzula ku rhurha ka muchini wo pfula valve ku va xikombiso xa gezi hi ku ya hi nawu wo karhi ivi yi yi rhumela ekamareni ro lawula. Xikombiso lexi xingava xikombiso lexi yaka emahlweni lexi kombisaka ku pfuleka kwihi na kwihi ka valve, kutani xinga tekiwa tani hi xiendlo xo hundzuluxela xa valve positioner.

Swiwitsi swa Maendzo (Xitirhisiwa xa Vuyelo bya Xiyimo):

Swiwitsi swa maendzo swi kombisa swiyimo swimbirhi swo tlula mpimo swa valve naswona hi nkarhi wun’we swi rhumela xikombiso xa xikombiso. Kamara ro lawula ri nga kumisisa xiyimo xa ku pfula ka valve hi ku ya hi xikombiso lexi naswona ri teka magoza lama fambelanaka.

Tianjin Tanggu Mati-Xisirhelelo xa Valve Co.,ltdva seketela thekinoloji ya xiyimo xa le henhla swinene ya tivalvu leti tshamaka leti tiyeke, ku katsa na leti tshamaka leti tiyekewafer valve ya phaphatani, Lug valve ya phaphatani, Double flange concentric valve ya phaphatani, Double flange eccentric valve ya phaphatani, Y-xigwitsirisi, valve yo ringanisela, Valve yo kambela tipuleti timbirhi ta Wafer, na swin’wana.
