Nyob rau hauv ib puag ncig bustling ntawm chaw nres tsheb roj, peb feem ntau pom qhov tshwm sim ntawm "khiav roj nozzles." Qhov no tsis yog ntawv tseeb tab sis muaj kev nyab xeeb tiag tiag. Kev ruaj ntseg breakaway couplings tiv thaiv cov xwm txheej tshwm sim los ntawm cov neeg tsav tsheb tsis saib xyuas tsis nco qab txiav cov roj nozzles, txiav txiav thiab tus kheej - sealing kom ruaj ntseg refueling ua haujlwm. Lub luag haujlwm tseem ceeb hauv Chaw Nres Tsheb Nkoj Kev Nyab Xeeb
Lub breakaway valve tau txiav tawm, nrog rau ob qho kev sib txuas uas muaj tus kheej - muaj peev xwm sib khi. Feem ntau ntsia rau ntawm cov khoom siv roj, cov khoom siv roj, lossis cov khoom siv roj / roj, cov cuab yeej no tiv thaiv kev sib tsoo los ntawm cov kav dej ntau dhau, muab kev tiv thaiv tshwj xeeb.
Hom Breakaway Valves thiab Tensile Requirements
Lub breakaway valve, ib qho khoom siv kev nyab xeeb tseem ceeb, feem ntau yog ntsia rau ntawm cov roj hoses lossis ntawm qhov chaw sib txuas ntawm lub nozzle thiab hose. Nws lub luag haujlwm tseem ceeb yog los tiv thaiv cov xwm txheej uas tshwm sim los ntawm tsis nco qab tshem lub nozzle tom qab refueling lub tsheb. Breakaway li qub yog categorized rau hauv nozzle breakaway li qub thiab hose breakaway li qub. Lawv qhov sib cais quab yuam yuav tsum nyob nruab nrab ntawm 800N thiab 1500N kom tsis txhob ua rau cov roj xa hluav taws xob lossis lub hose, lossis cuam tshuam lawv txoj haujlwm tiv thaiv. Nyob ntawm lawv qhov chaw teeb tsa, cov khoom tawg tuaj yeem raug cais raws li nozzle breakaway li qub lossis hose breakaway li qub. Txawm li cas los xij, lub zog tawg yuav tsum raug ntsuas kom tsim nyog-tsis qis lossis siab dhau. Kev quab yuam tsis txaus yuav ua rau tsis muaj kev cuam tshuam thaum muaj xwm txheej xws li roj rauj dej, cuam tshuam kev tiv thaiv. Hloov pauv, kev quab yuam ntau dhau tuaj yeem ua tsis tau zoo tiv thaiv cov khoom siv roj, hose, thiab cov khoom sib txuas. Yog li ntawd, peb yuav tsum ua raws li cov kev cai ntawm lub teb chaws tus qauv GB22380.2-2010, "Explosion-Proof Safety Technology for Fueling Stations - Part 2: Safety Requirements for Structure and Performance of Safety Breakaway Valves for Fuel Dispensers," kom ntseeg tau tias muaj kev ruaj ntseg ntawm qhov kev sib tsoo ntawm 0.0. rau 1500N.
Kev teeb tsa thiab kev siv ceev faj rau Breakaway Valves
Thaum txhim kho thiab siv cov khoom tawg tawm, ua raws li cov qauv tsim nyog thiab cov lus qhia tshwj xeeb kom ntseeg tau tias lawv muaj kev nyab xeeb thiab kev tiv thaiv zoo. Kev txhim kho thiab kev ua haujlwm yuav tsum ua raws li cov qauv, suav nrog kev tshuaj xyuas thiab tu. Ntxiv cov cuab yeej tiv thaiv yog txwv nruj. Xyuas kom cov connectors nyob tsis tu ncua, tiv thaiv kom tsis txhob muaj kab mob, thiab tswj qhov kub thiab txias nyob rau hauv qhov chaw. Kev tshuaj xyuas tsis tu ncua thiab kev saib xyuas kuj tseem yog qhov tseem ceeb los ua kom cov valve tawg hauv qhov zoo. Tsis tu ncua tshuaj xyuas lub breakaway valve. Yog tias loosening tshwm sim, ua kev tu lossis hloov tam sim ntawd. Ntxiv cov khoom siv tiv thaiv rau lub valve breakaway yog nruj me ntsis txwv tsis pub, vim nws yuav ua rau tsis zoo rau kev ua haujlwm. Tsis txhob disassemble sai - txuas fittings arbitrarily. Xyuas kom cov hoses tsis zoo los tiv thaiv kom tsis txhob ntws los yog detachment vim tawg. Siv cov dej huv, tsim nyog uas tau dhau los ntawm cov lim dej. Kev khiav hauj lwm kub rau breakaway li qub yuav tsum tau nruj me ntsis tswj nyob rau hauv tej yam kev cai. Tiv thaiv kom txhob muaj kab mob los ntawm cov hmoov hlau, hmoov av, los yog lwm yam impurities uas yuav cuam tshuam kev ua tau zoo los yog ua rau xau. Thaum txhim kho threaded breakaway li qub, xyuas kom nruj torque tsis tshaj tus nqi siab tshaj plaws los tiv thaiv kev puas tsuaj.
