Loj kab npauj npaim valve

Kev sib piv ntawm qhov loj kab npauj npaim valve thiab rooj vag valve:

Lub rooj vag valve muaj qhov ntim loj thiab siv qhov chaw loj. Nws tuaj yeem tiv taus siab heev.

Npauj npaim valve muaj me me ntim thiab occupies me me qhov chaw. Muaj peev xwm tiv taus lub siab yog me me.

Kev xaiv tshwj xeeb, tab sis kuj xav txog qhov kub ntawm qhov nruab nrab, valve sealing thiab packing.

Cov lus qhia tshwj xeeb qhia tias npauj npaim valve nrog nominal txoj kab uas hla ntau dua 50cm yuav tsum tau siv.

Loj kab npauj npaim valve yog lub teb chaws tseem ceeb cov khoom tshiab. Kev ua tau zoo ntawm phau ntawv npauj npaim valve txais yuav ob chav eccentric thiab tshwj xeeb inclined cone elliptical foob qauv. Nws daws qhov teeb meem uas lub sealing nto ntawm ib txwm eccentric npauj npaim valve tseem nyob rau hauv zawv zawg kev sib txhuam kev sib txhuam thaum lub sijhawm qhib thiab kaw ntawm 0 ° txog 10 ° thiab ua tiav cov txiaj ntsig ntawm kev sib cais ntawm qhov sealing nto ntawm lub sijhawm qhib thiab sealing ntawm lub sijhawm kaw, thiaj li ua kom lub neej ntev kev pabcuam thiab ua tiav qhov kev sib khi zoo tshaj plaws.

Daim ntawv thov ntawm loj kab npauj npaim valve:

Nws yog siv rau gas pipeline hauv kev lag luam sulfuric acid:inlet thiab qhov hluav taws xob ntawm lub tshuab hluav taws xob nyob rau hauv pem hauv ntej ntawm lub cub tawg, inlet thiab qhov hluav taws xob ntawm relay kiv cua, hluav taws xob demister series valve thiab txuas valve, inlet thiab qhov hluav taws xob ntawm S02 lub ntsiab blower, converter tswj, inlet thiab qhov hluav taws xob ntawm preheater, thiab lwm yam. Nws yog siv nyob rau hauv sulfur burning, hloov dua siab tshiab thiab qhuav absorption seem ntawm sulfur burning sulfuric acid system. Nws yog lub npe nyiam ntawm li qub rau leej faj hlawv sulfuric acid cog. Nws yog suav hais tias yog feem ntau ntawm cov neeg siv li npauj npaim li qub nrog kev ua haujlwm zoo sealing, lub teeb ua haujlwm, los ntawm cov khoom siv corrosion, kub tsis kam, yooj yim thiab hloov tau yooj yim, siv kev nyab xeeb thiab txhim khu kev qha, thiab tau siv dav. Nws kuj tseem siv dav hauv cov kav dej ntawm SO2, chav dej, cua, roj, ammonia, CO2, roj, dej, brine, alkali, seawater, nitric acid, hydrochloric acid, sulfuric acid, phosphoric acid thiab lwm yam khoom siv hauv tshuaj lom neeg, petrochemical, smelting, tshuaj, zaub mov thiab lwm yam lag luam raws li kev tswj hwm thiab kev cuam tshuam.

Nta ntawm lub taub loj npauj npaim valve:

① Cov qauv tsim tshwj xeeb ntawm peb txoj kev eccentricity ua rau lub sealing nto tsav yam tsis muaj kev sib txhuam thiab ncua kev pab cuam lub neej ntawm lub valve.

② Elastic foob yog tsim los ntawm torque.

③ Lub cuneiform sealing nto muaj kev ua haujlwm ntawm xoom xau them nyiaj.

④ Cov ntim me me, lub teeb yuag, lub teeb ua haujlwm thiab kev teeb tsa yooj yim.

⑤ Raws li cov neeg siv khoom xav tau, cov khoom siv pneumatic thiab hluav taws xob tuaj yeem teeb tsa kom tau raws li cov kev xav tau ntawm kev tswj chaw taws teeb thiab kev tswj hwm.

⑥ Cov khoom siv hloov pauv tuaj yeem siv rau txhua yam kev tshaj tawm, thiab tuaj yeem siv rau hauv ob sab phlu los tiv thaiv corrosion (F46, gxpp, Po, thiab lwm yam).

⑦ Nruam qauv sib txawv: clamp, flange, taub qab vuam.
