Kwiqondo lobushushu obuphezulu kunye nenkqubo yoxinzelelo oluphezulu lwezityalo ze-Thermal izityalo,I-J61y-320-I-320-I-SPRE-WOTT-Weldingyeka iValveiye yaba yinto ephambili ukuqinisekisa ukusebenza ngokukhuselekileyo kwe-540 ℃ iimeko zetekhnoloji yokutywina nenkqubo yokutywina nemveliso yemveliso kunye nenkqubo yezinto. Eli nqaku liza kuhlalutya ngokunzulu indlela yokulwa ivali yevali phantsi kweemeko zokusebenza ezivela kwimilinganiselo emine: Ukukhetha izinto ezibonakalayo, indawo yokutywina, inkqubo ye-welding, kunye noyilo loyilo.

I.

I-J61y-320-i-320I-Butt-Welting Stop Valveyamkela ingcinezelo yoxinzelelo lwe-cavity yokuziqiqa ngokuziqiqa, kwaye ukusebenza kwalo kutywina ngokuqinisekileyo nengcinezelo ephakathi. Xa uxinzelelo lwenkqubo ifikelela kwi-32MPA, umyinge woxinzelelo lwe-valve kunye neciko yevalve inyuswe nge-40%, ibuyisele ngokufanelekileyo utshintsho lwe-GAP olubangelwa kukwanda kwe-gap. Isitulo se-valve kunye ne-valve dic yokutywina i-Wellite esekwe kwi-carbide esekwe kwi-Stellide, ubukhulu be-Worlite ye-Wortite yi-HRC45-50mm, iqondo lokuvuza liqhubeka ne-¶0.01%.

I-STRAUVNTIONIT

I-1. Itywina eliphindwe kabini: I-Palve disf kunye nesitulo se-valve sihambelana ne-60 ° I-cone, indawo yoqhakamshelwano inyuke ngetywina, kwaye umlinganiso woxinzelelo unyuswe ukuya kwi-220n / mm2

I-2. I-tericasti yokuthengiswa kwempahla ye-Elastic: Intwasahlobo ye-Allol 718 Intwasahlobo isetwa ezantsi kwesihlalo sevalve sibuyekeze i-0.3mm

3. Inkqubo yokutywina kwesibini: Igrafu eguquguqukayo + 316l i-Staire yentsimbi yentsimbi ibeka i-pirve itreyini ye-valve ye-valve ye-valu

II. Inkqubo ephezulu yokunganyangekiyo

I-Valve iQu iVove yeVolve ye-G61y -y-320 yenziwa nge-chromium-molybdenum-dadim sentsimbi (njenge-15ccr1mo11v), enomgangatho ovuthayo kunye nomhlaba ovuthayo kunye nomhlaba ovuthayo. Ubunzulu becala le-nitriction yi-0.3mm, i-coultions ehleliweyo incitshisiwe kwi-0.12, kwaye ubomi obuchasene nobomi bunyuswe ngamaxesha ama-5. Iiparamitha eziphambili zezi zilandelayo:

Itekhnoloji yokuqhubela izinto ezibonakalayo:

I-valoum icinching: I-valve supt icinyiwe kwimeko ye-vacuum nge-1050 ℃, ngobulukhuni be-HRC 35-40

-Iplasma itshiza: Umhlaba wokutywina uphathwa ngefloome ephezulu yeflethi yokutshiza (i-Hvof), kunye ne-piresity ye-≤0.5%

-Umculo woxinzelelo: I-Post-Weld-Weld-Weld-Weld-Weld-Weld-Weld-Weld-Weld-Idy) igcinwa ngo-650 ℃ ye-2h ukuphelisa i-95% yoxinzelelo lwentsalela

III. Inkqubo ye-welding kunye netekhnoloji yoQhagamshelo

IValve ye-Stop J61Y-320 yamkela i-ASME B16.25 ye-Broot ye-Broove 37.5 ° ° 2mm.6mm, qinisekisa ukungena kwe-WOld ≥8mm. Amanqaku olawulo oluphambili lwenkqubo ye-Welding ibandakanya unyango olukhawulezileyo: Ukuhamba nge-200 ukuya kwi-50 ℃ ngaphambi kokuba i-welding ingayinciphisa umngcipheko wokuqhekeka kwe-hydrogen. Iqondo lokushisa ilawulwa ngaphakathi kwe-300 ℃, kunye ne-E9018-B3 idyling ye-rod isetyenziselwa i-milti-the the the kunye ne-welti-dlulise. Emva kwe-welding, i-100% yokuchongwa kwe-radiographic fivaw (RT) kunye novavanyo lwe-Penetion (PT) lovavanyo olungelulo lwenzakalisayo lwenziwa ngokungqinelana ne-ASTE B31.1 emiselweyo.

Umsebenzi we-welding:

-Inamandla e-thensle: ≥620MPA

-Izixhobo zefuthe (-29 ℃): ≥54J

-Ukuhla uvavanyo: I-180 ° ngaphandle kobuqhetseba

Ngobuchule bobutyebi abane Indlela yayo yobugcisa ibalulekile ukubaluleka koyilo lweqondo lobushushu obuphezulu kunye neevalva eziphezulu.

Xa ujonga i-valve ephezulu, ethembekileyo ye-globe ngokungathandabuzekiyo kukhetho olufanele ukuthathela ingqalelo. Inkampani ithathe inxaxheba ekunikezeleni ngezixhobo zamandla amandla kubandakanya izixhobo ze-turbine, kwaye iphumelele iingxowa-mali ngokubanzi kwiimveliso zayo eziphezulu kunye neenkonzo. Ngolwazi oluthe kratya okanye imibuzo, nceda tsalela inkonzo yabathengi engezantsi:
