I. Keeb kwm thiab kev loj hlob ntawm Gas Pressure Regulators
Lub invention ntawm gas siab regulators stemmed los ntawm qhov kev xav tau ceev rau kev siv roj tom qab lub Industrial Revolution. Nyob rau hauv lub xyoo pua puv 19, nrog rau kev siv ntau lub zog ntawm lub zog, nws tau pom tias kev siv ncaj qha ntawm - roj cua siab tuaj yeem ua rau cov khoom tawg thiab kev ua haujlwm tsis zoo. Muaj ib qho kev xav tau ceev ceev rau cov cuab yeej uas tuaj yeem tswj tau cov roj siab ruaj khov - qhov no yog tus qauv ntawm lub siab tswj hwm. Thaum ntxov siab regulators tau yooj yim heev nyob rau hauv cov qauv, feem ntau muaj xws li ib tug cam khwb cia hlau valve lub cev thiab ib tug manually adjustable valve core. Lawv tsuas tuaj yeem ua tiav qhov hnyav txo qis, nrog kev hloov pauv loj, thiab tsuas yog tsim nyog rau cov roj av tsawg, feem ntau yog siv rau cov kua dej methane hauv cov mines.
Txij li thaum lub xyoo pua 20th, nrog kev nce ntawm kev lag luam xws li metallurgy, tshuaj, thiab tshuaj, cov neeg tswj xyuas siab tau ua tiav lawv thawj qhov kev txhim kho loj: ib zaug - theem siab txo cov qauv maj mam loj hlob, cov khoom siv lub cev tau hloov kho rau cov hlau cam, diaphragms tau ua los ntawm cov roj hmab, thiab kev tswj xyuas qhov tseeb tau nce mus rau ± 10%. Los ntawm nruab nrab- xyoo pua 20th, ob-theem siab txo cov thev naus laus zis tau tshwm sim, tswj kev hloov pauv siab nyob rau hauv ± 5% los ntawm cov kauj ruam-los ntawm- kauj ruam hloov ntawm ob lub siab-txo chamber, ua tau raws li qhov xav tau ntawm precision manufacturing. Nkag mus rau lub xyoo pua 21st, kev txawj ntse tau dhau los ua ib qho qauv tshiab. Kev txawj ntse tswj lub siab, nruab nrog lub siab sensors, cov lus qhia digital, thiab kev hloov kho tsis siv neeg, tau tshwm sim. Lawv tsis tsuas yog saib xyuas cov ntaub ntawv siab hauv lub sijhawm tiag tiag tab sis kuj tseem pab tswj cov chaw taws teeb ntawm Is Taws Nem ntawm Yam (IoT), txhim kho kev hloov pauv thiab kev nyab xeeb.
Zhejiang Bohong Intelligent Technology Co., Ltd., ua raws li lub sijhawm, tau tsom mus rau kev lag luam innovation thiab R&D hauv kev lag luam ntawm cov cuab yeej siv siab, cov twj tso kua mis siab, thiab siab - purity gas siab regulators. Lub hom phiaj ntawm kev faib khoom hauv tsev thiab OEM kev lag luam, nyob rau hauv kev coj noj coj ua ntawm nws CEO, lub tuam txhab tau loj hlob los ntawm tsis muaj dab tsi rau ib yam dab tsi, thiab los ntawm ib yam dab tsi mus rau qhov zoo, dhau los ua lub hnub qub nce hauv kev ua lag luam hauv tsawg dua ob xyoos, nyiam cov neeg ua haujlwm hauv kev lag luam.
II. Classification ntawm Gas Pressure Regulators
Cov neeg tswj xyuas qhov siab tuaj yeem muab faib ua ntau txoj hauv kev, txhua hom sib xws rau cov kev xav tau tshwj xeeb:
