Vim tias lub pob valve feem ntau siv roj hmab, nylon thiab polytetrafluoroethylene ua cov khoom siv rau lub rooj zaum sealing, nws qhov kub thiab txias siv yog txwv los ntawm cov khoom siv rau lub rooj zaum sealing. Lub luag haujlwm txiav tawm ntawm lub pob valve yog ua tiav los ntawm kev nias lub pob hlau tawm tsam lub rooj zaum yas valve nyob rau hauv qhov kev ua ntawm qhov nruab nrab (floating ball valve). Nyob rau hauv qhov kev ua ntawm qee qhov kev sib cuag siab, lub rooj zaum sealing nplhaib deforms elastically thiab plastically nyob rau hauv qee qhov chaw. Qhov kev hloov pauv no tuaj yeem them rau qhov tseeb ntawm kev tsim khoom thiab qhov roughness ntawm lub pob, thiab xyuas kom meej tias lub pob valve sealing kev ua tau zoo.
Tsis tas li ntawd xwb, vim tias lub nplhaib kaw ntawm lub pob valve feem ntau yog ua los ntawm yas, thaum xaiv cov qauv thiab kev ua tau zoo ntawm lub pob valve, nws yog qhov tsim nyog los xav txog qhov tiv thaiv hluav taws thiab tiv thaiv hluav taws ntawm lub pob valve, tshwj xeeb tshaj yog hauv roj av, tshuaj lom neeg, metallurgical thiab lwm yam kev lag luam, hauv cov xov xwm flammable thiab explosive Lub pob valve siv rau hauv cov khoom siv thiab cov yeeb nkab system, thiab yuav tsum tau them sai sai rau kev tiv thaiv hluav taws thiab kev tiv thaiv hluav taws.
Feem ntau, nyob rau hauv ob-txoj hauj lwm kev hloov kho, kev ua tau zoo sealing nruj, av nkos, hnav, caj dab channel, qhib thiab kaw sai (1/4 tig qhib thiab kaw), siab siab txiav-tawm (qhov sib txawv siab loj), suab nrov tsawg, cavitation thiab vaporization, Hauv cov kav dej nrog me me ntawm qhov xau rau huab cua, me me ua haujlwm torque thiab me me kua tsis kam, lub pob li qub raug pom zoo.
Cov pob valve kuj tsim nyog rau cov kav dej uas muaj cov qauv sib dua, qhov txiav tawm siab tsawg (qhov sib txawv me me), thiab cov xov xwm corrosive.
Cov pob li qub kuj tseem siv tau rau hauv cov khoom siv kub qis (cryogenic) thiab cov kav dej.
Hauv cov txheej txheem oxygen piping ntawm kev lag luam metallurgical, cov pob li qub uas tau dhau los ua kev kho degreasing nruj heev yog qhov yuav tsum tau ua.
Thaum cov kab tseem ceeb hauv cov kav dej roj thiab cov kav dej roj yuav tsum tau faus rau hauv av, yuav tsum muaj cov pob valve uas muaj qhov loj tag nrho.
Thaum xav tau kev kho kom zoo, yuav tsum xaiv lub pob valve nrog cov qauv tshwj xeeb nrog lub qhov qhib V-puab.
Hauv roj av, petrochemical, tshuaj lom neeg, hluav taws xob, thiab kev tsim kho hauv nroog, cov hlau-rau-hlau kaw pob li qub tuaj yeem siv rau cov kav dej nrog qhov kub ua haujlwm siab dua 200 ° C.
Nortech yog ib qho ntawm cov chaw tsim khoom lag luam valve hauv Suav teb nrog daim ntawv pov thawj zoo ISO9001.
