Umhlahlandlela Wama-Valve Omoya | Kuchazwa Ama-Valve Ebhola, Uvemvane, Amasango kanye Nezi-Actuator

Iyini i-Pneumatic Valve?

Incazelo yeValvu Yomoya

A I-Velve Yomoyauhlobo lwevalvu yokulawula yezimboni eqhutshwa umoya ocindezelwe. Ngokuguqula ingcindezi yomoya ibe ukunyakaza komshini, i-actuator ivula, ivale, noma ilungise ivalvu ukuze ilawule ukugeleza koketshezi, amagesi, umusi, noma izinto ezibolile.
Imiklamo evamile ihlanganisa ama-valve ebhola asebenzisa umoya, ama-valve e-butterfly, ama-valve esango, kanye nama-valve okuvala asebenza ngokushesha.

Isimiso Sokusebenza Samavalvu Omoya

Umoya ocindezelwe ungena ekamelweni le-actuator, ucindezela i-piston noma i-diaphragm. Lokhu kunyakaza kuqhuba isiqu ukuthi sijikeleze noma sihambe ngendlela eqondile, okubangela ukuthi i-valve ivuleke noma ivale. Ezinhlelweni ezizenzakalelayo, i-actuator ilawulwa amasignali e-PLC noma e-DCS ukuze kulawulwe ukugeleza okunembile.

Imidiya Ejwayelekile

• Amagesi omoya kanye nalawo angasebenzi

• Cubungula amanzi kanye noketshezi lwezimboni

• Izinhlelo ze-steam

• Amakhemikhali ashisa kakhulu, agqwalisayo, noma ayingozi

Imisebenzi kanye nezinzuzo zamavalvu omoya

Imisebenzi Eyinhloko

Ukulawula Okuzenzakalelayo Kokuvula/Ukuvala

Ama-valve omoya avumela ukusebenza okude okuthembekile kumapayipi ezimboni, okususa isidingo sokungenelela ngesandla.

Ukulawula Ukulawula Okunembile

Uma ifakwe i-positioner, i-valve inganikeza ukulawula okuzinzile nokuphindaphindekayo kokugeleza, ingcindezi, noma izinga lokushisa.

Izinzuzo Eziyinhloko

Isikhathi Sokuphendula Okusheshayo (Ngokuvamile < 1 Sekondi)

Kuhle kakhulu ekuvalekeni okuphuthumayo kanye nezinhlelo zokuvikela.

Ukuphepha Okuphezulu Okunezakhiwo Ezingavimbeli Ukuqhuma Kwemvelo

Ngenxa yokuthi i-actuator isebenzisa umoya esikhundleni sikagesi, ingasetshenziswa ngokuphephile ezindaweni eziyingozi.

Impilo Yesevisi Ende kanye Nokulungiswa Okuphansi

Indlela yokusebenza ilula, kanti izingxenye ezimbalwa zingase zingasebenzi kahle.

Ifanelekela Amapayipi Anobubanzi Obukhulu Nanomfutho Ophezulu

Ama-valve ebhola lomoya kanye ne-butterfly asebenza kahle kakhulu kulezi zinhlelo zokusebenza ezidinga amandla.

Izingxenye Eziyinhloko Zamavalvu Omoya

I-Actuator Yomoya

I-Actuator Esebenza Ngodwa (Ukubuya Kwentwasahlobo)

Isebenzisa isipilingi ukubuyela endaweni ephephile yokuvala noma yokuvula ngesikhathi sokulahleka komoya.

I-Actuator Esebenza Kabili

Umoya unikezwa kuzo zombili izinhlangothi zepiston, okunikeza i-torque enkulu nokusebenza okubushelelezi.

Izinhlobo Zomzimba We-Valve

Ukuqhathanisa Phakathi Kwama-valve Omoya Nama-valve Esandla

Ukusebenza

Amavalvu omoya ahlinzeka ngokusebenza okuzenzakalelayo nangokude, kanti amavalvu esandla adinga ukuphathwa ngokomzimba.

Ukusebenza

Amavalvu omoya angashintsha njalo futhi asabela ngokushesha; amavalvu asetshenziswa ngesandla ahamba kancane futhi awafaneleki kangako emijikelezweni ezenzakalelayo.

Isicelo

Amavalvu omoya afanela imigqa yokukhiqiza ezenzakalelayo; amavalvu esandla ngokuvamile asetshenziswa emisebenzini elula, ephindaphindwayo.

Ukuqhathanisa Phakathi Kwamavalvu Omoya Namavalvu Kagesi

Umthombo Wamandla

• I-pneumatic: umoya ocindezelwe

• Ugesi: idrayivu yemoto

Isivinini

Ama-valve omoya ngokuvamile anikeza ukusebenza okusheshayo.

Ukuphepha

Ngenxa yokuthi akukho injini noma izinhlansi ezihilelekile, ama-valve omoya afanelekela izindawo eziqhumayo.

Ukulungiswa

Ama-actuator aqhutshwa umoya anezingxenye ezimbalwa ezihambayo futhi izidingo zokulungisa ziphansi.

Imibuzo Evame Ukubuzwa Mayelana Nama-valve Omoya

1. Ingabe ivalvu yebhola yomoya ingcono kunevalvu yebhabhathane yomoya?

Amavalvu ebhola ahlinzeka ngokuvaleka okungcono kakhulu, kuyilapho amavalvu ebhabhathane engabizi kakhulu kumapayipi amakhulu.

2. I-actuator yomoya ihlala isikhathi esingakanani?

Ngokuvamile phakathi kwemijikelezo engu-300,000 no-1,000,000, kuye ngekhwalithi yomoya kanye nezimo zokusebenza.

3. Ingabe ama-valve omoya adinga ukugcotshwa?

Ama-actuator amaningi ayazigcoba ngokwawo, kodwa ezinye izindlela zingadinga ukugcotshwa ngezikhathi ezithile.

4. Kufanele kusetshenziswe nini ivalvu yokuvala umoya?

Ekuvalekeni kwezimo eziphuthumayo (i-ESD), ukuhlukaniswa kwemidiya okuyingozi, noma izinhlelo zokusebenza zokuphepha eziphendula ngokushesha.

5. Uyini umehluko phakathi kwama-actuator asebenza kanye kanye nama-actuator asebenza kabili?

Ukusebenza okukodwa kunikeza isenzo esiphephile; ukusebenza kabili kunikeza i-torque ephezulu kanye nokulawula okuzinzile.
