Li-valve tsa ho hlahloba li fumaneha ka mefuta le litlhaloso tse fapaneng ho latela lintlha tse kang sebopeho sa sebopeho, thepa le ts'ebeliso. Kakaretso e qaqileng ea mefuta le litlhaloso tsa li-valve tsa ho hlahloba ke ena:
Taba ea pele, mofuta
1. Tlhophiso ka sebopeho
Valve ea ho hlahloba lifti: Valve ea ho hlahloba e nang le disc e thellang moleng o bohareng oa 'mele. Valve ena e ka kenngoa feela phaepheng e otlolohileng, coefficient ea ho hanyetsa mokelikeli e kholo. Ha media e le haufi le phallo, disc ea valve e buloa ka ho sutumelletsa media. Ha media e emisa ho phalla, disc ea valve e oela setulong ka boima ba eona ho thibela media ho tsoa ho countercurrent. Valve ea ho hlahloba lifti e na le mefuta e 'meli ea ho otloloha le e otlolohileng, valve ea ho hlahloba lifti e otlolohileng e tataisoa ke tsela e mahareng le ea ho tsoa le tataiso ea kanale ea setulo e otlolohileng, 'me valve ea ho hlahloba lifti e otlolohileng e tataisoa ke tsela e mahareng le ea ho tsoa le tataiso ea kanale ea setulo e tšoana, khanyetso ea eona ea phallo e nyane ho feta mofuta o otlolohileng.
Valve ea ho hlahloba ho tjheka: Valve ea ho hlahloba e nang le disc e bōpehileng joaloka disc le motsamao o potolohang ho potoloha shaft ea kanale ea setulo. Khanyetso ea eona hangata e tlase ho feta valve ea ho hlahloba ho phahamisa, e loketseng liketsahalo tse kholo tsa caliber. Valve ea ho hlahloba ho tjheka e ka boela ea aroloa ka valve e le 'ngoe, valve e habeli le valve e mengata ho latela palo ea li-valve, morero o ka sehloohong ke ho thibela seaplane ho emisa phallo kapa ho khutlela morao, ho fokolisa tšusumetso ea hydraulic.
Valve ea ho hlahloba serurubele: Valve ea ho hlahloba e nang le disc e potolohang phini setulong. Valve ea ho hlahloba disc e bonolo ka sebopeho, e ka kenngoa feela phaepheng e otlolohileng, 'me e na le ho koaloa ho fokolang.
Valve ea ho hlahloba liphaephe: Valve ea ho hlahloba e nang le disc e thellang moleng o bohareng oa 'mele. Ke valve e sa tsoa hlaha, e nyane, e bobebe, e na le theknoloji e ntle ea ts'ebetso, ke e 'ngoe ea litsela tsa nts'etsopele ea li-valve tsa ho hlahloba.
Valve ea ho hlahloba khatello: Valve ena e na le mosebetsi o kopaneng oa valve ea ho hlahloba lift le valve ea globe kapa valve ea Angle, 'me hangata e sebelisoa e le valve ea ho fepela metsi le mouoane ea ho khaola boiler.
Mefuta e meng: Hape e kenyelletsa valve ea ho hlahloba mofuta oa boima, valve ea ho hlahloba mofuta oa sekotlolo, valve ea ho hlahloba disc ea brake, valve ea ho hlahloba mofuta oa bolo, valve ea ho hlahloba mofuta oa diaphragm.
2. Hlopha ka thepa
Valve ea ho hlahloba tšepe: joalo ka valve ea ho hlahloba tšepe e lahliloeng, valve ea ho hlahloba koporo, valve ea ho hlahloba tšepe e sa hloekang, valve ea ho hlahloba tšepe ea carbon, valve ea ho hlahloba tšepe e entsoeng ka forged, jj.
Valve ea ho hlahloba e seng ea tšepe: joalo ka valve ea ho hlahloba ea polasetiki, valve ea ho hlahloba ea FRP, jj.
3. Hlopha ka mesebetsi
Valve ea ho hlahloba e khutsitseng: joalo ka valve ea ho hlahloba e khutsitseng ea DRVZ, valve ea ho hlahloba e khutsitseng ea DRVG, valve ea ho hlahloba e khutsitseng ea NRVR, jj.
Valve ea ho hlahloba e nang le sepheo se khethehileng: joalo ka valve ea ho hlahloba ea rabara ea SFCV, valve ea ho hlahloba ea double flap ea DDCV, jj.
Ea bobeli, litlhaloso
Litlhaloso tsa valve ea cheke hangata li hlahisoa ke bophara bo tloaelehileng (DN), 'me litlhaloso tse tloaelehileng ke DN15, DN25, DN50, DN80, DN100, DN150, jj. Ho phaella moo, ho na le litlhaloso tse kang maemo a khatello, mefuta ea khokahano (joalo ka likhokahano tse nang le khoele, tse nang le flange, tse welded le tse nang le clamp).
Mohlala, tlhaloso ea valve ea tlhahlobo ea selemo ea khoele ea H12W ke DN15-100mm, 'me sehlopha sa khatello ke 1.6-32MPa; Litlhaloso tsa li-valve tsa tlhahlobo ea lirurubele tsa H76H le H76W tse nang le li-disc tse peli ke DN50-1200mm, 'me sehlopha sa khatello ke 1.6-10MPa.
Sa boraro, khetha litlhahiso
Ha o kgetha valve ya ho hlahloba, ho hlokahala ho nahana ka dintlha tse kang sistimi e ikgethang ya diphaephe, dibopeho tse mahareng, kgatello ya ho sebetsa le mocheso. Dikgetho tse ding ke tsena:
Khetha mofuta o nepahetseng oa valve ea ho hlahloba le litlhaloso ho latela tataiso ea phallo le boholo ba phallo ea seaplane.
Nahana ka ho bola ha sekgahla, ho teteana le mocheso le mabaka a mang, kgetha thepa e loketseng.
Khetha mokhoa o nepahetseng oa khokahano ho latela litlhoko tsa sebaka sa ho kenya le tlhokomelo ea sistimi ea liphaephe.
Sheba lethathamo la lihlahisoa tsa moetsi le leqephe la litlhaloso tsa tekheniki ho netefatsa hore valve ea cheke e khethiloeng e fihlela litlhoko tsa sistimi.
Ka bokhutšoanyane, ho na le mefuta le litlhaloso tse fapaneng tsa li-valve tsa ho hlahloba, 'me khetho e lokela ho nahanoa ka botlalo ho latela litlhoko tsa sebele.
