Yuav ua li cas xaiv tus npauj txhim khu kev qha validfy valve?

Xaiv ib tug txhim khu kev qhaNpauj Npaim ValveYuav tsum muaj kev txiav txim siab ntawm nws cov qauv, khoom siv, thiab kev ua haujlwm.

Cov qauv hom yog lub hauv paus rau kev xaiv Npauj npaim li qub. Nruab nrab lub siab qis thiab chav nyob kub (xws li cov tshuab dej khoom (xws li cov khoom noj npauj npaim li qub, uas muaj tus nqi tsawg; Ob chav Eccentric npauj npaim li qub tuaj yeem siv rau hauv nruab nrab lub zog thiab nruab nrab ib puag ncig (xws li hauv nroog cua sov), nrog kev ua haujlwm kub tshaj plaws tshaj li cov kab hluav taws xob; Peb tus npauj npaim ib txwm yuav tsum raug xaiv rau qhov kub thiab txias thiab cov roj kub ua haujlwm hnyav (roj ntau dua, muaj lub neej muaj kev pabcuam siab ntev, thiab kev sib tw siab ntev, thiab kev sib cais ntev, thiab txhim kho lub neej ntev. Piv txwv li, thaum thauj cov corrosive media hauv cov kab hluav taws xob, 316 stainless hlau valve lub cev ntawm peb tus npauj npaim valve muaj peev xwm tiv thaiv kev fab tshuaj corrosion.

Cov khoom xaiv ncaj qha cuam tshuam txog lub durability ntawmNpauj Npaim Li QubCov. Cov khoom siv hluav taws xob yuav tsum sib phim ua haujlwm siab: cam khwb cia hlau valve lub cev tuaj yeem siv rau hauv cov pa dej qis thiab chav dej kub (xws li cua txias dej tshuab); Yuav tsum tau xaiv cov roj carbon lossis hlau steel lossis stainless hlau valve yuav tsum tau xaiv rau nruab nrab ib puag ncig (xws li roj pipelines); Muaj zog corrosion (xws li seasater desalination) yuav tsum muaj cov ntaub ntawv tshwj xeeb. Nyob rau hauv cov nqe lus ntawm cov khoom sealing, tsis yog corrosive media (xws li dej thiab huab cua) haum rau roj hmab sealing; Tshuaj lom neeg (xws li cov kua qaub thiab cov hauv paus) yuav tsum tau muab ntim nrog polytetrosraethylene (PTFE); Kev tuav hlau (xws li cov hlau stainless lossis tawv tawv nyias) yuav tsum tau siv rau hauv cov kev ntsuas kub thiab kub siab.

Ua hauj lwm kev yoog yog lub ntsiab cai tseem ceeb ntawmNpauj Npaim ValveXaiv. Nws yog ib qho tsim nyog los qhia meej hom nruab nrab (roj / kua / particle muaj nruab nrab), kub (pn10, thiab ntws tawm yam / hloov hom / kev tswj hwm hom / kev tswj hwm). Piv txwv li, yog tias cov dej phwj dej yuav xav tau kev tawm ntawm cov dej phwj tuaj ntau, nws yuav tsum xaiv lub cam ntawm DN300 lossis siab dua thiab roj hmab txoj hlua khau khiab; Thaum xa cov viscous media xws li syrup hauv cov khoom noj ua zaub noj, Eccentric Npauj Npaim yuav tsum tau siv los txo cov kev sib txhuam tsis kam.
