Ib.Lub zog ua haujlwm
Lub zog ua haujlwm ntawm lub valve yog hais txog lub peev xwm ntawm lub valve los tiv thaiv lub siab ntawm qhov nruab nrab.Lub valve yog cov khoom siv kho tshuab uas muaj lub siab sab hauv, yog li nws yuav tsum muaj lub zog txaus thiab nruj kom ntseeg tau tias siv tau ntev yam tsis muaj kev tawg lossis deformation.
二.sealing kev ua tau zoo
Lub sealing kev ua tau zoo ntawm lub valve yog hais txog lub peev xwm ntawm txhua qhov kev sib khi ntawm lub valve kom tiv thaiv kom tsis txhob tawm ntawm qhov nruab nrab.Nws yog qhov tseem ceeb tshaj plaws kev ua haujlwm Performance index ntawm lub valve.Lub valve muaj peb qhov kev sib khi: kev sib cuag ntawm qhov qhib thiab kaw qhov chaw thiab ob qhov sib khi ntawm lub rooj zaum valve;qhov chaw sib txuam ntawm cov ntim khoom thiab lub valve qia thiab lub thawv ntim khoom;kev sib txuas ntawm lub cev valve thiab lub kaus mom.Cov dej xau qub yog hu ua Internal to, uas feem ntau hu ua lax kaw, uas yuav cuam tshuam rau lub peev xwm ntawm Taike valve los txiav tawm qhov nruab nrab.Rau kev kaw-off li qub, tsis tso cai rau sab hauv.Ob qho kev xau tom kawg yog hu ua sab nraud to, uas yog, qhov nruab nrab los ntawm sab hauv ntawm lub valve mus rau sab nraud ntawm lub valve.Cov dej xau tuaj yeem ua rau cov khoom poob, ua paug ib puag ncig, thiab ua rau muaj xwm txheej hnyav.Rau cov nplaim hluav taws, tawg, tshuaj lom lossis xov tooj cua, tsis tso cai rau sab nraud, yog li Taike li qub yuav tsum muaj kev sib khi zoo.
, ntws nruab nrab
Tom qab qhov nruab nrab ntws los ntawm lub valve, kev poob siab (qhov sib txawv ntawm lub hauv ntej thiab nram qab ntawm lub valve) yuav tshwm sim, uas yog, lub valve muaj qee yam tsis kam mus rau qhov nruab nrab, thiab qhov nruab nrab siv qee qhov nyiaj ntawm lub zog los kov yeej qhov tsis kam ntawm lub valve.Los ntawm qhov kev xav ntawm kev txuag hluav taws xob, thaum tsim thiab tsim cov valve, qhov tsis kam ntawm lub valve mus rau qhov nruab nrab ntws yuav tsum raug txo kom ntau li ntau tau.
Hoisting force thiab hoisting moment Hoisting force and hoisting moment refers to the force or moment that must be apply to the valve to open or close.Thaum kaw lub valve, nws yog ib qho tsim nyog los tsim ib qho kev sib khi tshwj xeeb ntawm qhov qhib thiab kaw qhov chaw thiab ob qhov chaw sib khi ntawm lub rooj zaum, thiab tib lub sijhawm kov yeej qhov sib txawv ntawm lub qia valve thiab cov khoom ntim, cov xov ntawm lub rooj zaum. valve qia thiab txiv ntseej, thiab kev txhawb nqa ntawm qhov kawg ntawm lub qia valve.Kev sib txhuam quab yuam ntawm lwm qhov kev sib txhuam, yog li ntawd, yuav tsum tau siv qee lub zog kaw thiab kaw torque.Thaum lub sij hawm qhib thiab kaw cov txheej txheem ntawm lub valve, qhov yuav tsum tau qhib thiab kaw lub zog thiab qhib thiab kaw torque raug hloov, thiab tus nqi siab tshaj plaws yog nyob rau qhov kawg ntawm kev kaw lossis qhib qhov pib tam sim ntawd.Thaum tsim thiab tsim cov li qub, siv zog los txo lawv lub zog kaw thiab kaw lub zog.
四, qhib thiab kaw ceev
Qhov qhib thiab kaw nrawm yog qhia los ntawm lub sijhawm xav tau rau lub valve kom ua tiav qhov qhib lossis kaw qhov haujlwm.Feem ntau, tsis muaj qhov yuav tsum tau nruj me ntsis ntawm qhov qhib thiab kaw ceev ntawm lub valve, tab sis qee qhov kev ua haujlwm muaj qhov tshwj xeeb rau kev qhib thiab kaw ceev.Yog tias qee qhov yuav tsum tau qhib lossis kaw kom ceev kom tsis txhob muaj xwm txheej, qee qhov yuav tsum tau kaw qeeb kom tsis txhob muaj dej rauj, thiab lwm yam. Qhov no yuav tsum tau xav txog thaum xaiv hom valve.
五.Action rhiab heev thiab kev ntseeg tau
Qhov no yog hais txog qhov rhiab heev ntawm lub valve los teb rau cov kev hloov pauv hauv xov xwm tsis.Rau cov li qub uas muaj cov haujlwm tshwj xeeb xws li lub tshuab nqus tsev, lub siab txo cov li qub, thiab tswj cov li qub, nrog rau cov li qub nrog cov haujlwm tshwj xeeb xws li kev nyab xeeb li qub thiab cov ntxiab, lawv cov kev ua haujlwm rhiab heev thiab kev ntseeg siab yog qhov tseem ceeb tshaj plaws kev ua tau zoo.
六, kev pab lub neej
Nws qhia tau hais tias lub durability ntawm lub valve, yog ib qho tseem ceeb Performance index ntawm lub valve, thiab muaj kev lag luam tseem ceeb.Nws yog feem ntau qhia nyob rau hauv cov nqe lus ntawm tus naj npawb ntawm qhov qhib thiab kaw uas tuaj yeem lav qhov yuav tsum tau sib khi, thiab nws kuj tuaj yeem qhia tau raws li lub sijhawm siv.
Hais txog hom li qub siv, tshuab, metallurgy, petrochemical, tshuaj lom neeg, kev tsim kho hauv nroog thiab lwm yam kev lag luam muaj ntau hom li qub.Tshwj xeeb tshaj yog nyob rau hauv kev lag luam machinery, txhua yam ntawm li qub tau pib siv.Ntxiv nrog rau kev lag luam tshuab, npauj npaim li qub yog siv hauv petrochemical thiab metallurgy;diaphragm li qub yog siv rau hauv metallurgy, hluav taws xob fais fab thiab kev lag luam tshuaj;check li qub yog siv nyob rau hauv metallurgy, tshuaj lom neeg kev lag luam thiab petrochemical;nres li qub yog siv rau hauv kev lag luam roj av thiab tshuaj lom neeg;pob li qub feem ntau yog siv roj av, tshuaj lom neeg kev lag luam thiab metallurgy;regulating valve yog tsuas yog siv nyob rau hauv chemical kev lag luam, metallurgy, hluav taws xob fais fab thiab zaub mov;Lub siab txo valve feem ntau yog siv rau hauv petrochemical, tshuaj lom neeg kev lag luam thiab metallurgy.
