Xana valve yi endla yini?

Valve i xihlanganisi xa tiphayiphi lexi tirhisiwaka ku pfula naku pfala tiphayiphi, ku lawula tlhelo ra ku khuluka, ku lawula naku lawula ti parameters (mahiselo, ntshikelelo na nhlayo ya ku khuluka) ya xitirhisiwa lexi hundziseriwaka. Hi ku ya hi ntirho wa yona, yi nga avanyisiwa hi tivalvu to pfala, .ti valve to kambela, tivalvu leti lawulaka, na swin’wana.

Ti valve i swiphemu swa vulawuri eka tisisiteme ta vutleketli bya mati, leswingana mintirho yo pfala, ku lawula, ku hambukisa, ku sivela ku tlhelela endzhaku, ku tiyisisa ntshikelelo, ku hambukisa kumbe ku hunguta ntshikelelo wa ku tala. Ti valve ta tisisiteme ta vulawuri bya mati ti sukela eka ti valve to olova swinene to pfala ku ya eka ti valve to rharhangana swinene leti tirhisiwaka eka tisisiteme ta vulawuri bya xiothomethi.

Ti valve tinga tirhisiwa ku lawula ku khuluka ka tinxaka tohambana hambana ta swihalaki swofana na moya, mati, steam, ti corrosive media to hambana hambana, slurries, oils, liquid metals na radioactive media. Hikuya hi swilo leswi, ti valve na tona ti avanyisiwile hitivalvu ta nsimbi leyi hoxiweke, tivalvu ta nsimbi leyi hoxiweke, tivalvu ta nsimbi leyi nga riki na swilo (201, 304, 316, na swin’wana), tivalvu ta nsimbi ya chrome-molybdenum, tivalvu ta nsimbi ya chromium-molybdenum vanadium, tivalvu ta nsimbi ya duplex, tivalvu ta pulasitiki, tivalvu leti nga riki ta ntolovelo leti endleriweke wena, na swin’wana.

Hi ntirho na ku tirhisiwa

(1) Valava yo pfala

Muxaka lowu wa valve wutirhisiwa ku pfula naku pfala. Yi vekiwa hilaha kunga heriki eka ndzhawu yo nghena na yo huma ya swihlovo swo titimela na kuhisa, laha ku nghenaka naku huma ka switirhisiwa, na layini ya marhavi ya tiphayiphi (kukatsa na ti risers), naswona yinga tlhela yitirhisiwa tani hi valve yo humesa mati na valve yo humesa moya. Ti valve to pfala leti tolovelekeke ti katsati valve ta gede, ti valve ta globe, ti valve ta bolo na ti valve ta phaphatani.

Tivalvu ta gedeyi nga avanyisiwa hi nhonga leyi pfulekeke na nhonga ya ntima, ram yin’we na ram yimbirhi, wedge ram na parallel ram, na swin’wana na swin’wana Ku tiya ka valve ya gede a hi kahle, naswona swa tika ku pfula valve ya gede ya dyayimeta leyikulu; Vukulu bya miri wa valve i byintsongo kuya hi tlhelo ra ku khuluka ka mati, ku tiya ka ku khuluka i kutsongo, naswona nominal diameter span ya gate valve i yikulu.

Kuya hi tlhelo ra flow ya medium, globe valve yi avanyisiwile hi tinxaka tinharhu: straight-through type, right-angle type na direct flow type, naswona kuna ti rods leti pfulekeke na ti dark rods. Ku tiya ka ku pfala ka valve ya globe swikahle kutlula swa valve ya gede, miri wa valve wu lehe, ku tiya ka ku khuluka i kukulu, naswona maximum nominal diameter i DN200.

Spool ya valve ya bolo i bolo leyi pfulekeke. Plate-operated valve stem yi endla leswaku bolo yi pfuleka loko yi langutane na pipeline axis, naswona yi pfariwile hiku hetiseka loko yi jika 90°. Valve ya bolo yina matirhelo yokarhi yo lulamisa naswona yi pfala swinene.

Xipululu xavalve ya phaphatanii disiki ya xirhendzevutani leyi rhendzelekaka hi shaft leyi yimisiweke ya vertical pipe axis. Loko plane ya valve plate yi fambisana na axis ya pipe, yi pfulekile hiku hetiseka; Loko ram plane yi perpendicular eka axis ya phayiphi, yi pfariwile hiku hetiseka. Ku leha ka miri wa valve ya phaphatani i kutsongo, ku tiya ka ku khuluka i kutsongo naswona nxavo wu le henhla ku tlula wa ti gate valve na ti globe valve.

(2) Valava yo kambela

Muxaka lowu wa valve wutirhisiwa ku sivela ku tlhelela endzhaku ka medium, naswona wutirhisa kinetic energy ya fluid kuva yi pfula naku pfala hiku tisungulela loko ya khuluka kuya eka tlhelo leri hambaneke. Ku yima laha ku humaka pompo, laha ku humaka kona ntlhamu, na tindhawu tin’wana laha ku khuluka ka mati hi ndlela yo tlhelela endzhaku ku nga pfumeleriwiki. Kuna tinxaka tinharhu ta ti check valves: muxaka wa rotary opening, muxaka wo tlakusa na muxaka wa clamp. Eka ti swing check valves, fluid yinga khuluka ntsena kusuka eximatsini kuya exineneni naswona ya pfala hiku tisungulela loko ya khuluka kuya eka tlhelo leri hambaneke. Eka ti lift check valves, spool yi tlakuka kuya e henhla kuva yi endla ndlela loko mati ya khuluka kusuka eximatsini kuya exineneni, naswona spool yi pfariwile loko yi tshikileriwa eka xitulu loko ku khuluka ku tlheriseriwa endzhaku. Eka clamp-on check valve, loko fluid ya khuluka kusuka eximatsini kuya exineneni, valve core yi pfuriwa kuva yi endla ndlela, naswona valve core yi tshikileriwa kuya eka xitulu xa valve naswona yi pfariwa loko reverse flow yi tlheriseriwa endzhaku.

(3) Ku lawulati- valve

Ku hambana ka ntshikelelo exikarhi ka le mahlweni na le ndzhaku ka valve swi tiyisile, naswona loko ku pfuleka ka valve leyi tolovelekeke ku cinca eka mpimo lowukulu, mpimo wa ku khuluka a wu cinci ngopfu, naswona loko wu fika eka ku pfuleka ko karhi, mpimo wa ku khuluka wu cinca swinene, leswi vulaka leswaku matirhelo yo lulamisa a ma cinci kahle. Valve yo lawula yinga cinca spool stroke ku cinca ku tiya ka valve kuya hi tlhelo na vukulu bya signal, leswaku kuta fikeleriwa xikongomelo xo lawula valve yo khuluka. Ti valve to lawula ti avanyisiwile hi ti manual control valves na ti automatic control valves, naswona kuna tinxaka totala ta ti manual kumbe automatic control valves, naswona matirhelo ya tona yo lulamisa na wona ya hambanile. Ti valve ta vulawuri bya otomatiki ti katsa ti valve to lawula ku khuluka leti ti tirhaka hi toxe na ti valve to lawula ntshikelelo wa ku hambana leti ti tirhaka hi toxe.

(4) Ku hlantswa swilo

Vacuum yi katsa ti valve ta vacuum ball, ti vacuum baffle valve, ti vacuum inflation valve, ti pneumatic vacuum valve, etc. Ntirho wa yona wu le ka vacuum system, elemente ya vacuum system leyi tirhisiwaka ku cinca tlhelo ra ku khuluka ka moya, ku lulamisa volume ya ku khuluka ka moya, ku tsema kumbe ku hlanganisa phayiphi yi vuriwa vacuum valve.

(5) Swiyenge swa swikongomelo swo hlawuleka

Swiyenge swa swikongomelo swo hlawuleka swikatsa ti valve ta tinguluve, ti vent valve, ti blowdown valve, ti exhaust valve, ti filter, na swin’wana.

Valve yo humesa moya i xiphemu xo pfuneta lexi nga lavekiki eka sisiteme ya tiphayiphi, lexi tirhisiwaka ngopfu eka ti boilers, ti air conditioners, oyili na gasi, mphakelo wa mati na tiphayiphi ta drainage. Yitala ku vekiwa eka commanding height kumbe elbow ku susa gasi leyi tlulaka mpimo eka phayiphi, ku antswisa vukorhokeri bya matirhiselo ya tiphayiphi xikan’we naku hunguta ku tirhisiwa ka eneji.
