Nyob rau hauv Jinbin Rhiav, ib pawg ntawm peb-eccentric hard-sealed npauj npaim li qub yog hais txog yuav raug xa mus, nrog rau qhov ntau thiab tsawg ntawm DN65 txog DN400. Lub hard-sealedtriple eccentric npauj npaim valveyog ib tug high-performance kaw-off valve. Nrog nws cov qauv tsim tshwj xeeb thiab cov qauv kev ua haujlwm, nws tuav txoj haujlwm tseem ceeb hauv ntau qhov chaw ua haujlwm. Nws "peb eccentricities" qauv yog cov qauv tsim tseem ceeb: lubnyuaj sealing npauj npaim valveqia axis deviates los ntawm ob qho tib si hauv nruab nrab ntawm lub phaj npauj npaim thiab qhov chaw nruab nrab ntawm lub cev valve, thiab tib lub sijhawm, qhov nruab nrab ntawm lub sealing conical nto muaj qee lub kaum sab xis eccentricity txheeb ze rau qhov nruab nrab ntawm cov kav dej.

Cov qauv tsim no rhuav tshem txoj cai txav ntawm cov npauj npaim li qub. Thaum lub valve qhib, lub phaj npauj npaim thiab lub rooj zaum valve raug txiav tam sim ntawd. Thaum lub sijhawm kaw, lub phaj npauj npaim maj mam txav mus rau lub rooj zaum valve, thiab thaum kawg ua tiav kev sib khi los ntawm kev sib nrig sib sib zog nqus ntawm elastic lossis hlau sealing khub. Cov qauv no muaj txiaj ntsig zoo kom tsis txhob muaj kev sib txhuam ntawm lub phaj npauj npaim thiab lub rooj zaum valve thaum lub sijhawm qhib thiab kaw, ua kom lub neej ua haujlwm ntev ntawm lub sealing khub, thiab tib lub sij hawm txo qhov kev khiav hauj lwm torque, ua rau qhib thiab kaw ntawm lub valve ntau so thiab yooj yim.

Piv nrog rau lwm hom li qub, flanged nyuaj Seal npauj npaim valve muaj qhov zoo. Ua ntej, nws muaj kev sealing zoo heev. Cov hlau nyuaj sealing qauv tuaj yeem ua tiav xoom xoom thiab tiv taus siab txog li 1.6MPa - 10MPa, ua tau raws li qhov yuav tsum tau muaj ntawm ntau yam kev ua haujlwm siab. Secondly, nws muaj zog hnav thiab corrosion kuj. Nws yog tsim los ntawm cov khoom siv tawv tawv tshwj xeeb lossis cov hlau tsis muaj steel thiab tseem tuaj yeem ua haujlwm ruaj khov hauv qhov chaw hnyav xws li kub kub, siab siab thiab muaj zog corrosion. Thirdly, nws muaj lub neej ua haujlwm ntev. Vim tias qhov txo qis ntawm cov khoom siv, nws lub neej kev pabcuam tuaj yeem ncav cuag ntau dua 10 xyoo raws li kev ua haujlwm ib txwm ua, txo qis tus nqi kho. Plaub, nws yooj yim rau kev khiav lag luam thiab tuaj yeem tsav tau ntau txoj hauv kev xws li phau ntawv qhia, hluav taws xob thiab pneumatic, ua tau raws li qhov yuav tsum tau ua ntawm kev tswj tsis siv neeg hauv cov xwm txheej sib txawv.

Hauv kev siv tswv yim, nyuaj-sealed triple eccentric npauj npaim valve yog dav siv nyob rau hauv ntau yam lag luam. Hauv kev lag luam petrochemical, nws yog siv los tswj kev thauj mus los ntawm kev tshaj tawm xws li roj av, roj av thiab cov khoom siv tshuaj lom neeg; Hauv kev lag luam hluav taws xob, qhov ntws ntawm cov xov xwm xws li chav dej thiab dej txias tuaj yeem hloov kho kom ntseeg tau tias cov khoom siv hluav taws xob ruaj khov. Hauv kev lag luam metallurgical, nws muaj feem xyuam rau cov kav dej rau cov xov xwm xws li blast furnace gas, oxygen, thiab nitrogen. Hauv cov dej xa dej thiab cov dej ntws, nws feem ntau yog siv rau cov yeeb nkab txiav thiab kev khiav dej num hauv nroog cov dej hauv nroog thiab cov kav dej phwj.

Hais txog kev siv xov xwm, Tuam Tshoj triple eccentric npauj npaim valve muaj kev sib raug zoo. Nyob rau hauv cov nqe lus ntawm cov pa tawm, nws tuaj yeem siv rau cov pa roj carbon monoxide, thee gas, oxygen, nitrogen, chav dej, thiab lwm yam. Nyob rau hauv cov nqe lus ntawm cov kua xov xwm, nws muaj peev xwm tswj tau roj av, tshuaj tov, dej phwj tuaj, dej hiav txwv, thiab lwm yam. Tsis tas li ntawd, rau qee qhov roj-khoom los yog kua-khoom sib xyaw media uas muaj cov khoom thiab plua plav, lub valve no kuj tuaj yeem ua rau lawv ruaj khov, ua kom pom kev zoo.
