Orifice flange taw qhia:
Orifice flange yog ib qho khoom siv ntsuas dej ntws hauv cov kav dej. Nws muaj qhov zoo ntawm cov qauv yooj yim, siv tau yooj yim thiab ntsuas qhov tseeb. Nws yog siv dav hauv kev lag luam xws li roj av, tshuaj lom neeg kev lag luam, thermal zog, kev txuag dej, thiab lwm yam. Orifice flange muaj cov qauv flange, orifice phaj thiab sealing gasket. Orifice flange yog cais raws li cov qauv sib txawv, cov uas feem ntau siv yog ISO tus qauv thiab ASME B16.36 tus qauv.
◢Structure: ib khub ntawm flanges, orifice daim hlau, bolts, ceev, sealing gaskets, jack screws thiab ntsia hlau plugs.
◢ Lub phaj phaj yog lub phaj tshwj xeeb nrog qhov. Cov qhov sib txawv ntawm cov duab sib txawv yog siv los ua kom cov kua dej ntws tawm hauv cov ntawv sib txawv ntawm lub phaj orifice.
Txoj haujlwm ua haujlwm ntawm orifice flange
Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm lub qhov flange yog ntsuas tus nqi ntws raws li cov duab thiab kev teeb tsa ntawm lub qhov ntawm lub qhov ncauj. Thaum cov kua dej nkag mus rau hauv lub qhov ncauj, cov duab thiab kev teeb tsa ntawm lub qhov yuav ua rau cov kua ntws los ntawm kev thaiv, yog li ua rau lub siab sib txawv. Qhov sib txawv siab sensor yog siv los ntsuas qhov loj ntawm qhov sib txawv ntawm qhov sib txawv, thiab tus nqi ntws ntawm cov kua yog xam raws li cov qauv sib thooj.

FAQ
Dab tsi yog qhov txawv ntawm txoj kev sib txuas ntawm orifice flange thiab zoo tib yam flange?
Ordinary flanges yog ob lub kav dej, cov yeeb nkab fittings lossis cov khoom siv uas tau kho ua ntej ntawm lub phaj flange, thiab tom qab ntawd cov flange gaskets ntxiv ntawm ob lub phaj flange, thiab lawv tau txuas nrog bolts kom tiav kev sib txuas.
Orifice flanges yog siv los txuas lub orifice phaj (qhov ntsuas ib feem ntawm lub orifice flowmeter) rau cov yeeb nkab ntawm lub orifice flowmeter. Ob lub flanges txhim kho lub orifice phaj nyob rau hauv nruab nrab, thiab coj mus rau qhov sib txawv siab transmitter los ntawm cov ntsiab lus siab ntawm flanges los ntsuas qhov ntws.
