Cov Hlau Ductile Valves vs. Cov Hlau Cast Iron Valves

1. Hlau Ductile yog dab tsi?

Hlau zas yog ib hom hlau uas muaj zog thiab yooj ywm dua piv rau cov hlau cam khwb ib txwm muaj. Qhov no ua tiav los ntawm kev ntxiv me ntsis ntawm cov khoom xws li magnesium rau hauv cov hlau thaum lub sijhawm smelting. Qhov tshwm sim yog cov khoom siv uas tuaj yeem tiv taus kev ntxhov siab ntau dua yam tsis tawg, ua rau nws zoo tagnrho rau cov ntawv thov uas qhov kev tiv thaiv kev cuam tshuam tseem ceeb.

2. Hlau cam khwb cia yog dab tsi?

Hlau cam khwb cia, ntawm qhov tod tes, yog ib qho sib xyaw ntawm hlau, carbon, thiab silicon. Feem ntau, nws yog brittle dua li hlau ductile thiab paub txog nws cov yam ntxwv zoo heev casting thiab hnav tsis kam. Txawm li cas los xij, nws tsis muaj tib theem ntawm kev tawv, uas tuaj yeem ua rau tawg thaum muaj kev ntxhov siab lossis kev cuam tshuam hnyav.

3. Qhov Txawv Tseem Ceeb Ntawm Cov Hlau Uas Ua Los Ntawm Yas Thiab Cov Hlau Uas Ua Los Ntawm Hlau Uas Ua Los Ntawm Yas Yog Dab Tsi?

Qhov sib txawv ntawm cov kav dej hlau ductile thiab cov kav dej hlau cam khwb cia yog qhov tseem ceeb heev. Nov yog cov ntsiab lus tseem ceeb uas yuav tsum xav txog:

Lub zog thiab kev ywj pheej:Cov li qub hlau ductile muaj zog dua thiab yooj ywm dua vim lawv cov txheej txheem tsim khoom. Qhov no ua rau lawv haum rau cov ntawv thov siab thiab thaj chaw uas muaj cov khoom thauj hloov pauv.

Kev Tiv Thaiv Kev Xeb:Cov hlau ductile muaj kev tiv thaiv xeb zoo dua thaum muaj txheej txheej txaus. Cov hlau cam khwb cia yooj yim raug xeb, uas tuaj yeem ua rau nws lub neej luv dua, tshwj xeeb tshaj yog nyob rau hauv qhov chaw ntub dej lossis noo noo.

Qhov hnyav:Cov li qub hlau ductile feem ntau sib dua li cov li qub hlau cam khwb uas muaj tib qhov loj. Qhov no tuaj yeem ua rau kev teeb tsa yooj yim dua thiab txo cov nqi xa khoom rau cov chaw tsim khoom.

Tus nqi:Feem ntau, cov li qub hlau ductile kim dua thaum xub thawj vim yog cov khoom siv zoo dua. Txawm li cas los xij, qhov kev ruaj khov zoo dua tuaj yeem ua rau lawv pheej yig dua hauv lub sijhawm ntev.

Cov ntawv thov:Cov li qub hlau ductile feem ntau siv rau hauv cov dej hauv nroog thiab cov dej khib nyiab thiab cov txheej txheem kev lag luam, thaum cov li qub hlau cam khwb cia zoo dua rau cov kab ke qis thiab cov kev siv dej sab hauv. 

4. Koj Yuav Tsum Xaiv Dab Tsi: Cov Kav Dej Hlau Uas Ua Los Ntawm Hlau Los Yog Cov Kav Dej Hlau Uas Ua Los Ntawm Hlau Uas Ua Los Ntawm Hlau?

Qhov kev xaiv ntawm cov hlau ductile thiab cov hlau cam khwb cia feem ntau nyob ntawm koj cov kev xav tau tshwj xeeb rau kev siv. Yog tias koj xav tau lub valve uas tuaj yeem tswj tau qhov siab thiab muaj kev tiv taus kev cuam tshuam, cov hlau ductile yuav yog qhov kev xaiv zoo dua. Rau cov ntawv thov uas tus nqi yog qhov teeb meem tseem ceeb thiab qhov xav tau qis dua, cov hlau cam khwb cia yuav txaus.

5. Qhov twg pheej yig dua, hlau ductile lossis hlau cam khwb cia?

Cov hlau cam khwb feem ntau pheej yig dua li cov hlau ductile nyob rau hauv cov xwm txheej ua haujlwm ib txwm muaj. Qhov no yog vim tias cov txheej txheem tsim cov hlau cam khwb yog laus dua thiab yooj yim, tsis tas yuav ntxiv cov neeg sawv cev nodularizing (xws li magnesium) rau kev kho spheroidizing, thiab cov nqi khoom siv raw thiab cov nqi tsim khoom qis dua. Txawm li cas los xij, qhov kev lag luam no los ntawm tus nqi ntawm lub zog, kev tawv, thiab kev cuam tshuam - hlau cam khwb yog brittle thiab muaj qhov ntsuas siab qis dua. Hauv kev sib piv, txawm hais tias hlau ductile kim dua ib chav tsev, nws lub zog siab thiab kev tiv thaiv tawg zoo heev txhais tau tias nws tuaj yeem tsim nrog cov phab ntsa nyias dua thiab qee zaum txo qhov hnyav tag nrho. Los ntawm lub neej voj voog tag nrho, cov hlau ductile valves feem ntau tuaj yeem txo cov nqi kho tom qab thiab hloov pauv vim lawv muaj kev nyab xeeb siab dua, kev ntseeg siab, thiab lub neej ua haujlwm ntev dua. Yog li ntawd, qhov kev xaiv yuav tsum ntsuas qhov nqi yuav khoom luv luv thiab cov txiaj ntsig siv ntev: rau cov xwm txheej tsis tseem ceeb nrog lub siab ruaj khov thiab cov xwm txheej ua haujlwm me me, hlau cam khwb yog qhov kev xaiv pheej yig dua; thaum nyob rau hauv cov xwm txheej nrog siab siab, kev co, lossis kev nyab xeeb xav tau, kev nqis peev ntxiv rau hauv hlau ductile yog qhov tsim nyog cov nyiaj.

6. Xaus Lus

TWSyog ib lub npe nrov valve hauv Tianjin. Nws cov kab khoom npognpauj npaim li qub, lub qhov rooj vag, xyuas cov li qub, thiab lwm yam. Thaum xaiv lub valve, yog tias qhov xwm txheej ua haujlwm siab thiab qhov yuav tsum tau tiv thaiv qhov tawg siab, TWS ductile hlau valves tuaj yeem xaiv tau; yog tias qhov xwm txheej ua haujlwm tsis hnyav thiab cov peev nyiaj tsawg, nws cov hlau cam khwb cia valves pheej yig dua.
