Hi swihi swihoxo leswi talaka ku va na ku hoxiwa ka ti valve?

1. Swilo swa stomata

Lexi i xirhendzevutani lexintsongo lexi vumbiwaka hi gasi leyi endlelo ro tiya ra nsimbi ri nga balekiki endzeni ka nsimbi. Rirhangu ra yona rale ndzeni ri rhetela naswona rina gasi, leyingana reflectivity yale henhla eka ultrasonic wave, kambe hikuva kahle kahle yiri spherical kumbe ellipsoid, i point defect, leswi khumbhaka amplitude ya yona ya reflection. Xirhendzevutani xa moya eka ingot xi flattened kuya eka ndzhawu leyi nga na xihoxo endzhaku ko forging kumbe ku rhendzeleka, leswi pfunaka kuva swikumeka hiku kamberiwa hi ultrasonic.

2. Ku tlherisela endzhaku na ku ntshunxeka ka khumbi

Loko casting kumbe ingot yi titimela naswona yi tiya, volume yifanele kuhunguteka, naswona hollow defect ayi nge engeteriwi hi nsimbi ya mati. Ti vovities letikulu na leti hlanganisiweke ti vuriwa ti shrinkage holes, naswona ti voids letintsongo na leti hangalakeke ti vuriwa loose. Hikokwalaho ka nawu wa thermal expansion xikan’we na cold contraction, shrinkage hole yi boheke kuva kona, kambe kuna swivumbeko swohambana hambana, vukulu na tindzhawu letingana maendlelo yohambana hambana yo lulamisa, naswona yi hundzuka xihoxo loko yi anama kuya eka miri wa casting kumbe ingot. Loko ingot yinga tsemi shrinkage hole yi basile kutani yi tisa eka swiphemu swa forging, yita hundzuka residual shrinkage hole (residual shrinkage hole, residual shrinkage pipe).

3. Xiphemu xa slag

Slag eka maendlelo yo n’okisiwa kumbe refractory eka miri wa furnace yi rhurhumela eka nsimbi leyi nga mati, naswona yi kokiwa eka casting kumbe steel ingot loko yi cheriwa, leswi endlaka xihoxo xa slag clamp. Slag hi ntolovelo ayi vi kona yiri yoxe, yitala kuva yiri eka xiyimo xo enta kumbe yi hangalakile eka vuenti byohambana hambana, yifana na volume defects kambe yitala kuva na linearity yokarhi.

4. Ku hlangana

Switirhisiwa swa reaction eka maendlelo yo n’okisiwa (kufana na oxide, sulfide, na swin’wana) -swikatsa leswinga riki swa nsimbi, kumbe swilo leswi engeteriweke swa swiphemu swin’wana eka swiphemu swa nsimbi aswi n’oki hiku hetiseka naswona switshama swi endla swikatsa swa nsimbi, kufana na high density, high melting point components-tungsten, molybdenum, etc..

5. Ku hlamusela hi ndlela yin’wana

Ku hambanisiwa eka casting kumbe ingot ngopfu ngopfu swivula ku hambanisiwa ka swiphemu leswi vumbiwaka eka ku hangalasiwa lokunga ringaniki ka swiphemu eka maendlelo yo n’okisiwa kumbe endlelo ro n’oka ka nsimbi. Swihlawulekisi swa michini swa ndzhawu leyingana ku hambanisiwa swihambanile na swivumbeko swa michini swa matrix hinkwayo ya nsimbi, naswona ku hambana loku hundzaka eka standard range leyi pfumeleriwaka ku hundzuka xihoxo.

6. Ku hoxa swiphepherhele

Ku pandzeka eka casting swivangiwa ngopfu hi ntshikelelo wa shrinkage wa metal cooling solidification kutlula matimba yohetelela ya material, swifambelana na xivumbeko xa casting design na casting process, naswona switlhela swifambelana na cracking sensitivity ya thyaka rin’wana eka switirhisiwa swa nsimbi (kufana na sulphur yale henhla, cold brittleness, high phosphorus content, etc.). Eka spindle, kuta tlhela kuva na ku pandzeka eka shaft crystal, naswona eka billet forging leyi landzelaka, yita tshama eka forging tani hi ku pandzeka ka le ndzeni ka forging.

Handle ka sweswo, Tianjin Tanggu Water Seal Valve Co., Ltd. i thekinoloji ya xiyimo xa le henhla ya elastic seat valve leyi seketelaka mabindzu, swikumiwa irhaba xitulu wafer phaphatani valve, lug valve ya phaphatani, double flange concentric valve ya phaphatani, flange yimbirhivalve ya phaphatani ya eccentric, valve yo ringanisela, .wafer valve yo kambela tipuleti timbirhi, Y-Strainer na swin’wana. Eka Tianjin Tanggu Water Seal Valve Co., Ltd., hi tinyungubyisa hi ku nyika switirhisiwa swa xiyimo xo sungula leswi fikelelaka swiyimo swa le henhla swa indasitiri. Hi nxaxamelo wa hina wo anama wa tivalvu na switirhisiwa, u nga hi tshemba ku nyika ntlhantlho lowu hetisekeke eka sisiteme ya wena ya mati. Tihlanganisi na hina namuntlha ku dyondza swo tala hi switirhisiwa swa hina na ndlela leyi hi nga ku pfunaka ha yona.
