Ohlelweni lwamazinga okushisa aphezulu kanye ne-high-pressure steam yezitshalo zamandla afudumele, TheI-J61Y-320 High-Pressure Butt-Weldingyeka i-valveUye waba yingxenye esemqoka ukuqinisekisa ukusebenza okuphephile kwezimo eziphephile ezingama-540 ℃ izimo ze-Steam ngobuchwepheshe bayo bokubekwa uphawu okusha kanye nohlelo lwezinto ezibonakalayo. Le ndatshana izohlaziya ngokujulile inqubo yokuvuthwa kwe-valve ngaphansi kwezimo zokusebenza ezedlulele kusuka ezingxenyeni ezine: Ukukhethwa kwezinto ezibonakalayo, ukwakheka uphawu, ukwakheka kwe-welding, nokwakhiwa kwe-welding.

I. ingcindezi yokuqinisa uphawu lokuqiniseka

I-J61Y-320 ephezulu kakhuluI-butt-welding stop valveI-Adoduli i-Mail-Cavity Pressung Design Design Design, futhi ukusebenza kwalo kokubopha kuhlobene kahle nengcindezi ephakathi. Lapho ingcindezi yesistimu ifinyelela ku-32MPA, isilinganiso sengcindezi yokubekwa uphawu somzimba we-valve bese ikhava ye-valve inyuka ngo-40%, isinxephezela ngempumelelo ukuguqulwa kwegebe okubangelwa ukunwetshwa kwe-thermal. Isihlalo se-valve kanye nobuso be-valve disc surving buhlelwe nge-carbide esuselwa ku-cobalt esekelwe e-stellite, ubukhulu be-weld ungqimba, ubulukhuni bufinyelela i-HRC45-50, futhi izinga lokuvuza lisagcinwa ku-≤0.01% ngaphansi kwezimo ezingama-540 ℃ ngaphansi kwezimo ezingama-540

Ukuvalwa kwesakhiwo okusha:

1. I-Double Con Isikhala Seal: I-Valve Disc nesihlalo se-valve sifaniswe nesigaxa esingu-60 °, indawo yokuxhumana inyuswa ngophawu olungama-35% ngokuqhathaniswa nophawu olucaba, futhi isilinganiso sengcindezelo se-BATION sikhuphukile ku-220N / MM2

2. Indandatho yesinxephezelo se-Enwestic

I-3. Isistimu Yokubopha Kwesekondari: I-Graphite Evumelana Nezimo + 316l Insimbi Engagqwali Insimbi Engagqwali isethwe entanyeni yesiqu se-valve ukwakha umugqa wokuvikela uphawu kabili

II. Uhlelo oluphakeme lokumelana nokushisa kwezinto ezibonakalayo

Umzimba we-valve we-stop valve J61Y-320 wenziwe nge-chromium-molybdenum-vanadium yensimbi (njenge-15cr1mo1v), enomoya othosiwe. Ukujula kwengqimba ye-nitrided kungu-0.3mm, ukungqubuzana okunciphisiwe kuncishiswa ku-0,12, futhi impilo ye-anti-scratch inyuswa ngamahlandla ama-5. Amapharamitha asemqoka asemqoka anje:

Ubuchwepheshe bokucubungula ezibonakalayo:

- I-vacuum junching: Isiqu se-valve sicinywe endaweni ye-vacuum ngo-1050 ℃, ngobulukhuni be-HRC 35-40

- Ukufafaza kwe-Plasma: Ingaphezulu lokubekwa uphawu liphathwa ngenqubo ephezulu yokufafaza i-velofity flame (hvof), nge-porolity ye-≤0.5%

- Ukukhululeka kwengcindezi: Ukwelashwa okushisa okushisayo kwe-Post-Weld (PHTT) kugcinwa ku-650 ℃ ngo-2h ukuqeda ama-95% e-Welding Reside Recident stress

III. Inqubo ye-Welding nobuchwepheshe bokuxhumeka

I-Stop Verve J61Y-320 Adomets ASME B16.25 I-Standard Butt Welding uxhumano, i-Groove Angle 37.5 ° ± 2.5 °, Blunt Enqenqemeni ubukhulu Amaphoyinti okulawula asemqoka wenqubo yokufaka i-welding afaka ukwelashwa okwenziwa ngaphambi kwesikhathi: Preheating to 200-250 ℃ ngaphambi kokushiswa kwe-welding anganciphisa ingozi yokuqhekeka okubangelwa yi-hydrogen. Ukushisa kwe-interlayer kulawulwa kungakapheli i-300 ℃, kanye ne-E9018-B3 Welding Rod kusetshenziselwa ungqimba oluningi kanye nokuphangwa okuningi. Ngemuva kokushiswa, i-100% ye-radiographic fine detection detecting (RT) nokuhlolwa kokungena (PT) Ukuhlolwa okungeyona eyonakalisayo kwenziwa ngokuhambisana ne-ASME B31.1 Standard.

Ukusebenza okuhlangene kwe-Welding:

- Amandla we-Tensile: ≥620MPA

- Umthelela wamandla (-29 ℃): ≥54j

- Ukuhlolwa kokugoba: 180 ° ngaphandle kwemifantu

Ngokusebenzisa izinto ezinobukhulu bokwenziwa kwezinto zokwenziwa kwezinto zokwakha kanye nokulungiswa, i-j61y-320 High-Weld-Welded Stop Valve ithole ukusebenza okuphezulu kokuvuza konyaka <5ppm ngaphansi kokusebenza okuphephile kanye nokusebenza kwezomnotho kwezitshalo zamandla aphephile. Umzila wayo wezobuchwepheshe unesithenjwa esibalulekile ngokubaluleka kokuklanywa kwama-valve aphezulu okushisa nama-high-pressure.

Uma ufuna ikhwalithi ephezulu, ethembekile ama-valves e-Globabe, akungabazeki ukuthi ukhetha ukukhetha. Inkampani isebenza ngokukhethekile ekunikezeni imishini ehlukahlukene yamandla kubandakanya izesekeli ze-turbine, futhi ithole isimemezelo esibanzi ngemikhiqizo nezinsizakalo ezisezingeni eliphakeme. Ngeminye imininingwane noma imibuzo, sicela uxhumane nensizakalo yamakhasimende ngezansi:
