LCC stands rau Low Temperature Microalloyed Steel, siab -cov hlau tshwj xeeb zoo. Cov khoom siv no muaj lub siab tawv, siab zog, thiab zoo heev qis - qhov kub thiab txias, ua rau nws siv dav hauv kev thauj mus los ntawm cov roj av, marine engineering, metallurgy, thiab lwm yam. Tshwj xeeb tshaj yog nyob rau hauv qis-kub, qis- daim ntawv thov siab, LCC pob li qub qhia tau zoo tshwj xeeb.
Lub cev lub cev ntawm cov cam khwb cia hlau cryogenic pob valve feem ntau yog ua los ntawm ASTM A352 LCC cryogenic cam khwb cia hlau, uas tuaj yeem ua haujlwm ruaj khov hauv ib puag ncig xws li -46℃txog -196℃(saib rau ASME B16.34 tus qauv). Nws cov qauv sab hauv suav nrog lub pob, lub rooj zaum, qia, thiab cov khoom sib khi. Lub pob yog hollow los txo qhov txias txias, thiab lub rooj zaum siv reinforced polytetrafluoroethylene (PTFE) los yog hlau tawv foob kom sib npaug qis-kub elasticity thiab hnav tsis kam.
Txoj Cai Ua Haujlwm thiab Qis-Qhov Kev Ntsuas Kub tau piav qhia
1. Dynamics ntawm kev qhib thiab kaw
Thaum lub valve qhib, lub valve qia tig lub pob 90 degree, aligning lub pob ntawm - qhov nrog lub raj xa dej, tso cai rau cov xov xwm ntws. Thaum kaw, lub pob rotates yuav perpendicular mus rau lub pipeline kev taw qhia, cia siab rau lub compression deformation ntawm sealing nto los thaiv cov xov xwm. Nyob rau hauv qis- qhov kub thiab txias, qhov sib txawv ntawm qhov sib txawv ntawm thermal expansion ntawm cov ntaub ntawv yuav tsum tau muab xam kom raug (xws li, qhov sib txawv ntawm expansion coefficients ntawm cam khwb cia hlau thiab PTFE yog kwv yees li 1.5 × 10⁻⁵ /℃) kom tsis txhob foob tsis ua hauj lwm.
2. Kev ntsuas los tiv thaiv qis-Qhov kub thiab txias
- Khoom siv: Lub cev valve yuav tsum tau txais kev kho mob cryogenic (immersion hauv cov kua nitrogen ntawm -196℃rau ntau tshaj 2 teev) kom ruaj khov rau cov qauv metallographic.
- Fluid Compatibility: Haum rau kev tshaj tawm xws li liquefied natural gas (LNG) thiab kua oxygen; qhov tsim siab ntau yog feem ntau Class 150-Class 900 (raws li API 6D qauv).
