Yini Okufanele Uyenze Uma Ivalvu Inokucindezela Kwangaphakathi Okuphezulu Futhi Kunzima Ukuyijika?

Okuqukethwe

1. Isimo semboni kanye namaphuzu obuhlungu

2. Ukuhlaziywa kobunzima bezobuchwepheshe

3. Izixazululo ezintsha

4. Idatha yecala kanye nokuqinisekiswa komphumela

5. Imibono yochwepheshe kanye nezitayela zesikhathi esizayo

6. Isithasiselo:{1}}Umfutho we-valve womfutho ophezulu{2}}ithebula lokuqhathanisa lesixazululo

1. Isimo semboni kanye namaphuzu obuhlungu

Emkhakheni we-petrochemical, amandla kagesi, isitoreji se-LNG nezokuthutha, inkinga yobunzima bokuzungezisa-amavalvu okucindezela aphezulu (10-42MPa) ngaphezu kwe-DN200 iya ngokuya igqama. Ngokwezibalo ze-China Valve Industry Association ngo-2024, ngaphezu kuka-63% wezingozi zezimboni zihlobene ngokuqondile nama-valve jam, lapho izimo zengcindezi ephezulu zibalelwa ku-78%. Le nkinga ayikhulisi nje kuphela izindleko zokusebenza zonyaka kanye nokugcinwa kwezindleko ngama-yuan ayizigidi eziyizinkulungwane eziyi-1.2-1.5, kodwa futhi iba umgoqo ovimbela ukukhiqizwa okuphephile.

2. Ukuhlaziywa kobunzima bezobuchwepheshe

2.1 Izimbangela zokumelana nokujikeleza kwe-valve yomfutho ophezulu

Umthombo wedatha: Umbiko Wokuhlola we-Beijing High and Medium Pressure Valve Research Institute 2024

3. Izixazululo ezintsha

3.1 Indlela yokwenza kahle idizayini

Ukuqamba okusha kwesakhiwo

Ubuchwepheshe be-Dual disc diversion: ngokusebenzisa-isakhiwo sokunciphisa ingcindezi yesiteji ezimbili, amandla{1}ephoyinti ancipha ngo-60% (idatha ekaliliwe)
I-Bellows sealing system: iqeda ukungqubuzana kokupakisha futhi inciphisa ukuvuleka nokuvala i-torque ye-valve ye-DN250 ibe ngu-35N·m

Ukuthuthukiswa kwezinto

Umthombo wedatha: Ukuhlolwa okuqhathanisayo kwe-Shanghai Valve Factory ngo-2024

3.2 Ukuthuthukiswa kokuphathwa kokusebenza nokulungisa

Isistimu yokulayisha kuqala ehlakaniphile: ukuqapha{0}}isikhathi sangempela sokucindezelwa kwesiqu se-valve ngokusebenzisa ama-strain gauge, ukulungiswa okuzenzakalelayo kwamandla okulayisha kuqala (iphutha<5%)

Ubuchwepheshe bokuhlanza i-ultrasonic: ukusula amakristalu e-valve cavity njalo ngekota, kunciphisa izinga lokunamathela ngo-82%

Imodeli yamawele edijithali: ukwakha i-algorithm yokubikezela ingcindezi{0}}ngokunemba okungu-±7%

4. Idatha yecala kanye nokuqinisekiswa komphumela

Iphrojekthi yokuvuselela isiteshi ethola i-LNG (2024)

Inhlanganisela yobuchwepheshe: I-Stellite alloy valve core + i-hydraulic booster mechanism + uhlelo lokuqapha oluku-inthanethi.

5. Imibono yochwepheshe kanye nezitayela zesikhathi esizayo

U-Li Ming, umqondisi we-Pressure Vessel Institute of China Special Inspection Institute, waveza: "Ngo-2025,{1}}amavalvu okucindezela aphezulu azobonisa amathrendi amathathu amakhulu:

I-Actuator ehlakaniphile: ubuchwepheshe obuhlanganisiwe be-piezoelectric ceramic drive, ukuminyana kwe-thrust kukhuphuke izikhathi ezi-5

I-Bionic surface engineering: ukufunda esakhiweni sesikhumba sikashaka ukuthuthukisa-i-hydrophobic valve cavity, izinga lokuguguleka lehle ngo-70%

Ukusebenza nokugcinwa kwamawele edijithali: qopha idatha yomjikelezo wempilo ephelele nge-blockchain, ukunemba kokubikezela kufinyelela ku-95%
