Kev lag luam li qub yog cov khoom tseem ceeb hauv ntau qhov kev lag luam, los ntawm roj thiab roj mus rau kev tswj dej thiab kev ua tshuaj lom neeg. Kev nkag siab txog cov txheej txheem tsim khoom ntawm cov cuab yeej tseem ceeb no pab qhia txog kev txawj ntse, kev ua tau zoo, thiab thev naus laus zis koom nrog hauv lawv qhov kev tsim khoom. Hauv qab no, peb nthuav dav cov theem tseem ceeb ntawm valve ntau lawm.
1. Kev xaiv khoom
Thawj kauj ruam hauv kev tsim valve yog xaiv cov khoom tsim nyog. Qhov kev xaiv nyob ntawm lub valve lub hom phiaj daim ntawv thov, nrog rau qhov kub thiab txias, siab, thiab hom kua dej nws yuav lis. Cov ntaub ntawv uas muaj xws li:
- Carbon Steel: Haum rau cov tshuab ua haujlwm siab.
- Stainless hlau: Zoo tagnrho rau corrosive ib puag ncig.
- Bronze thiab tooj dag: Feem ntau yog siv rau cov dej haus.
- Cov khoom siv alloy: Tsim los rau cov xwm txheej hnyav xws li kub siab lossis tshuaj lom neeg.
2. Casting thiab Forging
Valve lub cev thiab cov khoom siv feem ntau yog ua los ntawm cov txheej txheem casting lossis forging:
- Casting: Molten hlau yog nchuav rau hauv pwm los tsim cov duab nyuaj. Xuab zeb casting, peev casting, thiab tuag casting yog ntau txoj kev.
- Forging: Cov hlau yog zoo li nyob rau hauv kev kub siab thiab kub, ua kom muaj zog thiab txo qhov porosity. Forging yog nyiam rau cov kev ua haujlwm siab.
3. Tshuab dhos
Thaum cov ntaub ntawv nyoos raug tsim, machining ua kom txhua yam ua tau raws li cov lus qhia meej. CNC tshuab yog dav siv los ua kom tiav qhov ntev thiab du nto. Cov txheej txheem tseem ceeb suav nrog:
- Tig: Rau cylindrical qhov chaw xws li valve stems.
- Milling: Ua kom cov duab tiaj tus lossis tsis sib xws.
- Drilling: Rau kev tsim cov qhov tseeb, xws li cov rau lub rooj zaum valve.
4. Kev sib dhos
Tom qab machining, cov khoom yog sib sau ua ke rau hauv lub valve ua haujlwm. Cov kauj ruam no suav nrog:
- Txhim kho lub qia, lub rooj zaum, thiab disc lossis pob.
- Ntxiv cov ntsaws ruaj ruaj, gaskets, lossis O-rings rau kev ua haujlwm tsis zoo.
- Sib dhos lub actuator lossis handwheel rau kev ua haujlwm.
5. Kev xeem zoo
Kev ruaj ntseg zoo yog ib theem tseem ceeb hauv kev tsim cov valve. Cov neeg tsim khoom ua qhov kev sim nruj kom ntseeg tau tias lub valve ua tau raws li cov qauv thoob ntiaj teb, xws li API, ANSI, lossis ISO. Cov kev ntsuam xyuas muaj xws li:
- Kev Ntsuas Hydrostatic: Tshawb xyuas lub valve lub zog thiab cov ntaub ntawv pov thawj muaj peev xwm nyob rau hauv siab.
- Kev kuaj Cryogenic: Ua kom muaj kev ua haujlwm hauv qhov kub tsis tshua muaj siab rau cov khoom tshwj xeeb li qub.
- Kev kuaj hluav taws: Txheeb xyuas cov qauv tsim hluav taws xob rau kev nyab xeeb-tseem ceeb.
6. Kev kho saum npoo
Valves raug kho los txhim kho durability thiab tsis kam mus rau ib puag ncig yam. Cov txheej txheem no suav nrog:
- Txheej: Siv epoxy lossis hmoov txheej los tiv thaiv corrosion.
- Polishing: Rau stainless hlau li qub siv nyob rau hauv ib puag ncig huv si.
- Galvanizing: Ntxiv cov zinc txheej rau cov khoom siv hlau rau kev tiv thaiv corrosion.
7. Ntim thiab Shipping
Thaum cov li qub dhau qhov kev kuaj xyuas zoo, lawv tau ntim los tiv thaiv kev puas tsuaj thaum caij tsheb npav. Daim ntawv lo kom raug suav nrog cov khoom tshwj xeeb, ntawv pov thawj, thiab cov txheej txheem saib xyuas.
Cov txheej txheem tsim valve yog kev sib xyaw ua ke ntawm cov cuab yeej siv siab heev, kev txawj ua haujlwm zoo, thiab kev tswj xyuas nruj. Txhua kauj ruam, los ntawm kev xaiv cov khoom siv mus rau qhov kawg tshuaj ntsuam xyuas, ua kom cov khoom ua tau raws li cov qauv kev lag luam siab tshaj plaws thiab ua tiav nws lub luag haujlwm hauv cov ntawv thov kev lag luam tseem ceeb.
Los ntawm kev nkag siab txog cov txheej txheem ntxaws ntxaws no, cov neeg muaj feem cuam tshuam tuaj yeem txaus siab rau qhov nyuaj thiab kev ntseeg siab ntawm cov khoom siv niaj hnub no.
