Tshawb nrhiav kev txo qis Valve Chaw tsim khoom: Kev tsim kho tshiab, thev naus laus zis, thiab cov thawj coj hauv kev lag luam

Introduction

Siab txo cov li qub (PRVs), tseem hu ua lub siab tswj hwm, yog cov khoom tseem ceeb hauv kev tswj cov dej hauv ntau qhov kev lag luam. Cov cuab yeej no cia li txo thiab tswj qhov siab ntawm cov kua dej-xws li dej, chav dej, roj, lossis huab cua-los ntawm lub siab nkag mus rau qis dua, predetermined qhov hluav taws xob siab. Qhov kev ua haujlwm no tseem ceeb heev rau kev tiv thaiv cov khoom siv qis qis, ua kom muaj kev ua haujlwm zoo, thiab tiv thaiv kev ua haujlwm tsis zoo vim muaj kev kub ntxhov ntau dhau.

Nyob rau hauv niaj hnub engineering, PRVs ua lub luag haujlwm tseem ceeb hauv kev siv xws li kev faib dej hauv nroog mus rau cov txheej txheem kev lag luam xws li kev tsim tshuaj lom neeg thiab kev tsim hluav taws xob. Qhov kev thov rau kev txhim khu kev qha PRVs tau tsav lub lag luam kev sib tw ntawm cov tuam txhab uas txuas ntxiv tsim kho tshiab kom ua tau raws li cov qauv nruj rau kev nyab xeeb, kav ntev, thiab kev ua haujlwm. Tsab ntawv xov xwm no piav qhia txog kev ua haujlwm ntawm PRVs, suav nrog lawv cov qauv kev ua haujlwm, hom, txheej txheem tsim khoom, cov neeg ua haujlwm tseem ceeb hauv kev lag luam, kev tsim kho tshiab, kev siv, thiab kev xaiv. Los ntawm kev tshuaj xyuas cov ntsiab lus no, peb tau txais kev nkag siab txog yuav ua li cas cov tuam txhab tsim kho lub neej yav tom ntej ntawm kev tswj cov kua dej.

Kev ua lag luam PRV thoob ntiaj teb tau cuam tshuam los ntawm cov khoom xws li nroog loj, kev nthuav dav, thiab kev tswj hwm cov cai rau kev siv hluav taws xob thiab kev nyab xeeb. Cov tuam txhab ua lag luam tau nqis peev ntau hauv kev tshawb fawb thiab kev tsim kho kom tsim cov li qub uas tiv taus huab cua thaum txo qis zog. Raws li peb tshawb nrhiav cov ncauj lus no, nws pom tseeb tias kev xaiv cov chaw tsim khoom tsim nyog suav nrog kev ntsuas cov kev qhia tshwj xeeb nrog cov kev xav tau zoo xws li tus nqi thiab kev ua raws cai.

 

Yuav Ua Li Cas Siab Txo Valves Ua Haujlwm: Kev piav qhia

Ntawm lawv lub hauv paus, PRVs ua haujlwm ntawm lub hauv paus ntsiab lus ntawm kev sib npaug, siv cov khoom siv tshuab kom nkag siab thiab kho qhov sib txawv ntawm qhov sib txawv. Ib qho PRV ib txwm muaj lub cev lub cev, lub diaphragm lossis piston, lub caij nplooj ntoos hlav, thiab kev hloov kho. Qhov chaw nres nkoj inlet tau txais cov kua dej siab, thaum lub qhov hluav taws xob xa cov kev txo qis.

Cov txheej txheem pib thaum cov kua nkag mus rau hauv lub valve. Lub downstream siab ua rau lub diaphragm los yog piston, uas yog counterbalanced los ntawm lub caij nplooj ntoos hlav. Yog tias lub qhov hluav taws xob siab tshaj qhov teeb tsa, lub diaphragm compresses lub caij nplooj ntoos hlav, ib nrab kaw lub valve kom txwv tsis pub ntws thiab txo qhov siab. Hloov pauv, yog tias lub qhov hluav taws xob qhov hluav taws xob poob qis dua qhov teeb tsa-vim qhov xav tau nce hauv qab-lub caij nplooj ntoos hlav txuas ntxiv, qhib lub valve dav kom tso cai ntau dua thiab rov ua kom lub siab xav tau.

Technically, qhov no tuaj yeem piav qhia siv Bernoulli cov ntsiab lus thiab cov dej sib npaug sib npaug. Lub siab poob thoob plaws lub valve yog tswj hwm los ntawm kev khiav coefficient (Cv), qhov twg Cv = Q / √ (ΔP / SG), nrog Q yog tus nqi ntws, ΔP lub siab sib txawv, thiab SG qhov tshwj xeeb lub ntiajteb txawj nqus ntawm cov kua. Cov neeg tsim khoom tsim PRVs kom tswj tau qhov ruaj khov Cv thoob plaws cov xwm txheej sib txawv, kom ntseeg tau tias tsawg kawg hysteresis (lag hauv teb).

Hauv kev tsav tsheb PRVs, tus tsav tsheb me me ua rau lub siab qis qis thiab tswj lub ntsiab valve qhib. Qhov kev tsim no tso cai rau kev tswj kom meej nyob rau hauv cov xwm txheej siab, raws li tus kws tsav dav hlau ua kom pom kev quab yuam. Direct-acting PRVs, ntawm qhov tod tes, cia siab rau lub caij nplooj ntoos hlav-diaphragm tshuab, ua rau lawv yooj yim dua tab sis tsis haum rau kev poob siab loj.

Kev tu yog qhov tseem ceeb; Cov khib nyiab tuaj yeem ua rau lub pob valve, ua rau lub siab hloov pauv. Cov neeg tsim khoom feem ntau suav nrog cov strainers lossis kev ntxuav tus kheej kom txo tau qhov no. Kev nkag siab txog cov tshuab ua kom pom tseeb yog vim li cas PRV tsim yog ib qho kev sib xyaw ntawm cov tshuab engineering thiab cov dej dynamics, nrog rau cov tuam txhab tsom rau cov khoom uas tiv thaiv corrosion thiab hnav.

 

Hom Lub Siab Txo Valves

Siab txo cov li qub tuaj nyob rau hauv ntau hom, txhua tus haum rau cov kev siv tshwj xeeb thiab kev ua haujlwm. Thawj qhov kev faib tawm yog nyob ntawm txoj kev ua kom raug thiab tsim qauv.

1. Direct-Acting PRVs: Cov no yog hom yooj yim tshaj plaws, siv lub caij nplooj ntoos hlav-loaded diaphragm los tswj lub valve qhib. Lawv yog qhov zoo tagnrho rau kev siv qis qis, qis qis xws li cov dej hauv tsev. Cov txiaj ntsig muaj xws li qhov loj me thiab cov lus teb ceev, tab sis lawv tuaj yeem ua rau muaj kev poob qis (siab txo qis nrog kev nce siab) hauv cov xwm txheej xav tau siab.
2. Pilot-Operated PRVs: Ntau txoj hauv kev, cov no siv lub valve los tswj lub ntsiab valve. Lawv ua tau zoo nyob rau hauv high-flow, high-pressure ib puag ncig, muab zoo dua qhov tseeb thiab tsawg kawg nkaus poob. Feem ntau hauv kev lag luam chav tshuab, lawv tuaj yeem tswj qhov sib piv siab txog 20: 1.
3. Balanced PRVs: Cov no suav nrog qhov ntsuas piston los tiv thaiv qhov cuam tshuam ntawm qhov nkag siab, txo cov quab yuam uas xav tau rau kev ua haujlwm. Lawv yog siv nyob rau qhov twg inlet siab sib txawv dav, kom ntseeg tau raws li qhov hluav taws xob siab.
4. Siab-Relieving lossis Drop-Tight PRVs: Cov no tuav xoom txaus thaum downstream siab mus txog qhov teeb meem, tiv thaiv cov xau. Lawv yog ib qho tseem ceeb hauv kev tiv thaiv hluav taws kom tsis txhob muaj dej pov tseg.
5. Electronic lossis Smart PRVs: Cov hom tshiab sib txuas cov sensors thiab actuators rau kev hloov kho tej thaj chaw deb, feem ntau txuas rau SCADA systems rau kev saib xyuas lub sijhawm.

Cov neeg tsim khoom sib txawv lawv cov khoom los ntawm cov hom no, nrog rau qee qhov tshwj xeeb hauv kev hloov pauv rau kev lag luam niche xws li kws tshuaj, qhov uas tsis muaj menyuam yog qhov tseem ceeb.

 

Kev tsim cov txheej txheem ntawm Kev Siv Siab Txo Valves

Kev tsim khoom ntawm PRVs suav nrog kev ua haujlwm siab ua haujlwm kom ntseeg tau tias muaj kev ntseeg siab. Cov txheej txheem feem ntau pib nrog kev xaiv cov khoom siv. Cov ntaub ntawv uas muaj xws li tooj dag rau corrosion kuj nyob rau hauv dej siv, stainless hlau rau high-temperature chav, thiab cam khwb cia hlau rau nqi-zoo industrial siv.
