Globe li qub yog cov khoom tseem ceeb hauv ntau yam kev lag luam, tshwj xeeb hauv kev tswj cov kua dej. Lawv cov kev tsim kho muaj xws li intricate design thiab precision manufacturing, nrog casting yog ib qho tseem ceeb ntawm kev tsim cov li qub. Kab lus no tshawb txog cov txheej txheem, qhov zoo, daim ntawv thov, thiab cov ntsiab lus tseem ceeb ntawm lub ntiaj teb valve casting.

Dab tsi yog Globe Valve Casting?

Globe valve casting yog hais txog cov txheej txheem ntawm kev tsim lub ntiaj teb li qub los ntawm cov hlau molten rau hauv pwm, tso cai rau nws kom khov, thiab tom qab ntawd machining nws kom ua tau raws li cov qauv tsim tshwj xeeb. Txoj kev no yog xaiv rau nws lub peev xwm los tsim cov duab complex nrog siab precision thiab sib xws.

Globe Valve

Cov Cheebtsam tseem ceeb ntawm Globe Valves:

• Lub cev: Lub ntsiab casing uas tsev nyob rau hauv lub Cheebtsam.
• Bonnet: Ib daim npog uas kaw lub valve lub cev, feem ntau bolted los yog screwed rau.
• Disc: Cov khoom txav tau uas tswj kev ntws los ntawm kev nce lossis nqis.
• Rooj: Qhov chaw tiv thaiv uas lub disc seals.
• Qe: Txuas lub disc mus rau lub actuator los yog handwheel.

Cov txheej txheem Casting rau Globe Valves

Step-by-Step Casting txheej txheem:

1. Qauv Ua: Ib tug qauv, feem ntau yog ua los ntawm ntoo, yas, los yog hlau, yog tsim los replicate lub valve lub cev.
2. Pwm Tsim: Cov qauv yog muab tso rau hauv ib lub hwj, thiab xuab zeb lossis lwm yam khoom siv molding yog ntim rau ntawm nws. Tus qauv yog ces muab tshem tawm, tawm hauv kab noj hniav nyob rau hauv cov duab ntawm lub valve.
3. Core Ua: Yog hais tias lub valve muaj cov kab sab hauv lossis cov duab nyuaj, cores yog tsim los tsim cov yam ntxwv no.
4. Ncuav: Molten hlau, feem ntau yog hlau, stainless hlau, los yog tooj liab, yog nchuav rau hauv pwm.
5. Cooling thiab Solidification: Cov hlau txias thiab solidifies hauv pwm.
6. Caw tawm: Cov pwm yog sib cais, thiab cov ntxhib casting raug tshem tawm.
7. Ua tiav: Lub casting undergo ntxuav, sib tsoo, thiab machining kom ua tiav qhov kawg qhov ntev thiab nto tiav.

Rooj 1: Common Casting Materials rau Globe Valves

Qhov zoo ntawm Globe Valve Casting

• Lub zog: Castings tuaj yeem tsim los ua kom muaj zog thiab txo qhov hnyav.

Kev siv ntawm Globe Valves

Kev lag luam:

• Roj thiab Roj: Rau kev tswj qhov ntws ntawm cov roj crude, natural gas, thiab cov khoom ua kom zoo.
• Kev kho dej: Siv nyob rau hauv cov dej faib tshuab rau kev khiav thiab kaw.
• Kev ua tshuaj lom neeg: Los daws cov tshuaj corrosive kom zoo.
• Tshuaj: Rau kev tswj kom meej ntawm cov dej ntws hauv cov txheej txheem tsim tshuaj.
• Lub zog tiam: Hauv chav dej thiab chav dej kom tswj kev ntws thiab siab.

Daim ntawv thov ntawm Globe Valve

Cov ntawv thov tshwj xeeb:

• Flow Regulation: Globe li qub yog qhov zoo tagnrho rau kev siv throttling qhov twg xav tau kev tswj xyuas meej.
• Kev Tswj Siab: Siv los tswj lossis txo qhov siab hauv cov kav dej.
• kaw: Muaj peev xwm nres kiag li thaum kaw tag nrho.

Tsim Kev xav rau Globe Valve Casting

• Cov yam ntxwv ntws: Globe li qub muaj txoj hauv kev ncaj nraim, uas tuaj yeem ua rau lub siab poob. Kev txiav txim siab tsim qauv yuav tsum suav nrog txo qhov kev poob qis no.
• Foob thiab Rooj: Xyuas kom muaj kev sib khi nruj ntawm lub disc thiab lub rooj zaum kom tsis txhob muaj dej ntws tawm.
• Qhov loj thiab qhov hnyav: Optimizing qhov loj thiab qhov hnyav thaum tswj lub zog thiab kev ua haujlwm.
• Kev xaiv khoom: Xaiv cov khoom siv raws li cov kua dej ua haujlwm, kev ua haujlwm, thiab ib puag ncig yam.

Rooj 2: Tsim Parameters rau Globe Valves

Kev Tswj Xyuas Zoo hauv Globe Valve Casting

• Dimensional soj ntsuam: Xyuas kom cov khoom ua tau raws li qhov ntev uas siv cov cuab yeej ntsuas qhov tseeb.
• Kev kuaj khoom: Chemical composition thiab mechanical properties testing kom paub meej cov khoom siv.
• Kev ntsuas siab: Valves raug kuaj xyuas kom ntseeg tau tias lawv tuaj yeem tiv taus kev ua haujlwm siab.
• Kev Xeem Leak: Tshawb xyuas cov xau ntawm cov pob qij txha thiab cov ntsaws ruaj ruaj.
• Kev tshuaj xyuas qhov muag: Nrhiav qhov tsis xws luag xws li porosity, tawg, los yog suav nrog.
