Pob Valve Muaj Sijhawm Sijhawm

Txij li thaum pob li qub feem ntau siv roj hmab, nylon thiab PTFE ua cov ntaub ntawv sib khi lub nplhaib, lawv qhov kev pabcuam kub yog txwv los ntawm lub rooj zaum sealing nplhaib khoom. Qhov kev txiav tawm ntawm lub pob valve yog ua tiav los ntawm cov khoom siv hlau sib tsoo ntawm lub rooj zaum hauv lub rooj zaum hauv qhov nruab nrab (floating pob valve). Nyob rau hauv qhov kev txiav txim ntawm ib qho kev sib cuag siab, lub valve lub tog raj sealing nplhaib yuav raug elastic-yas deformation nyob rau hauv cov cheeb tsam. Qhov deformation no tuaj yeem them nyiaj rau qhov raug thiab qhov roughness ntawm lub pob thiab xyuas kom lub sealing kev ua tau zoo ntawm lub pob valve.
Thiab txij li thaum lub rooj sib khi lub nplhaib ntawm lub pob valve feem ntau yog ua los ntawm cov yas, thaum xaiv cov qauv thiab kev ua haujlwm ntawm lub pob valve, qhov hluav taws kub tsis kam thiab kev tiv thaiv hluav taws ntawm lub pob valve yuav tsum raug txiav txim siab, tshwj xeeb tshaj yog nyob rau hauv roj av, tshuaj lom neeg kev lag luam, metallurgy thiab Lwm lub tuam tsev, hauv cov khoom siv hluav taws xob thiab cov khoom tawg thaum lub pob valve siv hauv cov khoom siv thiab cov kav dej, yuav tsum tau them nyiaj ntau dua rau kev tiv thaiv hluav taws thiab tiv thaiv hluav taws.
Feem ntau, nyob rau hauv ob txoj hauj lwm hloov, nruj sealing kev ua tau zoo, av nkos, hnav, shrinkage channel, ceev ceev qhib thiab kaw kev txiav txim (1/4 tig qhib thiab kaw), high-pressure cutoff (loj siab sib txawv), tsis tshua muaj suab nrov, cavitation thiab vaporization phenomena, Pob li qub tau pom zoo rau cov raj xa dej nrog me me ntawm cov pa tawm mus rau hauv qhov chaw, me me ua haujlwm torque, thiab cov kua dej me me.
Pob li qub kuj tseem tsim nyog rau cov kav dej nrog cov qauv teeb pom kev zoo, tsis tshua muaj siab txiav tawm (qhov sib txawv me me), thiab corrosive media. Pob li qub tuaj yeem siv tau hauv cov khoom siv cryogenic (cryogenic) thiab cov kav dej. Hauv cov pa oxygen pipeline hauv kev lag luam metallurgical, pob li qub uas tau ua tiav kev kho degreasing yuav tsum tau siv. Thaum cov kab tseem ceeb hauv cov kav dej thiab cov kav dej yuav tsum tau muab faus rau hauv av, tag nrho-bore welded pob li qub yuav tsum tau siv. Thaum tswj kev ua tau zoo, yuav tsum tau xaiv lub pob valve nrog cov qauv tshwj xeeb nrog V-shaped qhib yuav tsum tau xaiv. Hauv kev lag luam roj av, petrochemical kev lag luam, tshuaj lom neeg kev lag luam, hluav taws xob hluav taws xob, thiab kev tsim kho hauv nroog, hlau-rau-hlau sealing pob li qub tuaj yeem siv rau hauv cov kav dej uas muaj kev ua haujlwm kub siab tshaj 200 degrees.
