Marine Breakaway Coupling (MBC)
Kuj tseem hu ua: Offshore Breakaway Coupling los yog Marine Pull-Tshuaj sib txuas ceev. Cov cuab yeej no ua haujlwm raws li lub luag haujlwm tseem ceeb ntawm kev nyab xeeb rau kev hloov pauv dej (suav nrog roj, tshuaj, LNG, thiab lwm yam) ntawm cov nkoj thiab cov davhlau ya nyob twg lossis cov chaw tawm ntug dej hiav txwv. Nws yog feem ntau ntsia nruab nrab - hose los yog nyob rau hauv lub davhlau ya nyob twg kawg ntawm ib tug loading caj npab.
I. Core Functions
Tsis siv neeg sib cais thaum dhau-Ntxhais: Nyob rau hauv cov xwm txheej ntawm lub nkoj drift, nro los ntawm cua thiab nthwv dej, los yog mooring kab tsis ua hauj lwm, lub coupling yuav txiav cais thaum lub tensile quab yuam mus txog ib tug preset (piv txwv li, 1-5 tons).
Instantaneous Self- Kaw: Internal bi- cov lus qhia cov lus qhia kaw tam sim ntawd thaum sib cais, ua kom xoom xoom kom tsis txhob muaj kuab paug ib puag ncig, hluav taws kub nyhiab, thiab tawg.
Kev Tiv Thaiv Cov Khoom Siv: Tiv thaiv cov hoses, thauj cov caj npab, thiab cov kav dej los ntawm kev tawg lossis txhawb kev puas tsuaj vim muaj kev sib zog ntau dhau.
Passive Safety: Yuav tsum tsis muaj hluav taws xob sab nraud; kev khiav hauj lwm yog purely mechanically triggered, kom ntseeg tau siab.
II. Txoj Cai Ua Haujlwm (Peb Kauj Ruam)
Kev sib txuas ib txwm: Sab hauv li qub tau qhib tag nrho, tso cai rau cov kua dej ntws zoo; lub coupling yog ruaj los ntawm shear pins los yog ib tug locking mechanism.
Tshaj -Tension Trigger: Vessel drift generates axial nro; Thaum lub zog no dhau ntawm qhov pib ua ntej, lub shear pins raug txiav los yog lub tshuab xauv raug tso tawm.
Kev sib cais + Sealing: Lub caij nplooj ntoos hlav quab yuam tsav lub valve cores ntawm ob qho kawg kom kaw ib txhij, ua tiav kev foob; lub coupling sib cais, yog li tiv thaiv tag nrho cov system.
III. Hom qauv
Lub cev: Tsim los ntawm 316 stainless hlau, aluminium alloy, los yog tooj dag los xyuas kom meej tiv thaiv dej hiav txwv corrosion.
Valve Core: Nta lub pob valve lossis dual nrov plig plawg valve tsim kom ntseeg tau tias ob-kev taw qhia kev sib khi.
Trigger Mechanism: suav nrog shear pins (calibrated rau qhov tshwj xeeb ua kom nruj) thiab springs (muab lub hwj chim rau tus kheej - kaw).
Kev Sib Txuas Xaus: Muaj nrog flange lossis clamp txuas kom ntseeg tau tias muaj kev sib raug zoo nrog cov qauv hoses.
IV. Key Parameters (Common Specifications)
Loj: DN25-DN400 (1 "-16").
Kev ntsuas siab: PN16-PN40 (16-40 bar).
Khoom siv: 316 Stainless Hlau (nyiam dua rau kev siv dej hiav txwv), Aluminium Alloy, lossis tooj dag.
Tig Nrho: 1-10 tons (customizable raws li kev khiav hauj lwm tej yam kev mob).
Qhov kub thiab txias: -196℃(rau cov ntawv thov LNG) txog +200℃(rau cov ntawv thov roj kub). V. Application Scenarios
Nkoj - mus rau -Ncej: Kev thauj khoom thiab kev thauj khoom ntawm cov roj tanker thiab cov khoom siv tshuaj lom neeg.
Nkoj - mus rau - Nkoj: Offshore bunkering, lightering, thiab FPSO offloading.
Offshore Platforms: Kev sib txuas ntawm cov platforms thiab shuttle tankers.
LNG Bunkering: Hloov cov xov xwm cryogenic; tiv thaiv cov dej ntws thiab tawg.
VI. Distinction los ntawm Standard Couplings
Standard Quick Couplings: Los ntawm txhais tes xauv; tsis muaj zog-tso tawm mechanism; tsis siv neeg kaw -off.
Marine Emergency Release Couplings: Tsis siv neeg triggering + Bi-kev taw qhia tsis siv neeg kaw-tawm + Tsis kam mus rau qhov hnyav marine ib puag ncig; muaj kev nyab xeeb siab.
VII. Txoj Cai Xaiv
Media: Roj, tshuaj, LNG (cryogenic).
Pipe Diameter thiab Pressure: Yuav tsum phim cov hose specifications thiab system khiav hauj lwm siab.
Trigger Tension: xam raws li cua thiab yoj tej yam kev mob, hom nkoj, thiab hose ntev.
Khoom siv: 316 stainless hlau yog pom zoo rau cov dej hiav txwv ib puag ncig.
Cov Qauv: Ua raws li cov cai hauv hiav txwv xws li OCIMF thiab ISO 18758.
VIII. Kev Nyab Xeeb Tus Nqi
Kev Tiv Thaiv Leak: Tiv thaiv cov pa phem hauv hiav txwv, hluav taws kub, thiab tawg.
Kev Tiv Thaiv Cov Khoom Siv: Txo kev puas tsuaj rau cov hoses thiab thauj khoom caj npab, yog li txo tus nqi kho.
Kev Ua Raws Cai: Txaus siab rau thoob ntiaj teb kev cai maritime kev tiv thaiv kev ua qias tuaj.
