Cov Khoom Siv Txawv
Hlau Forged:
Cov hlau forged yog tsim los ntawm kev ua kom cov hlau billets sov thiab ua kom lawv zoo li qub hauv qab kev siab siab. Cov txheej txheem no ua kom cov qauv nplej zoo dua, ua rau muaj zog dua, tawv dua, thiab tiv taus qhov kub siab / kub ib puag ncig. Cov qib feem ntau suav nrogASTM A105 (cov hlau carbon)thiabASTM A182 (cov hlau tsis xeb).
Hlau cam khwb cia:
Cov hlau cam khwb cia yog tsim los ntawm kev nchuav cov hlau uas yaj rau hauv cov pwm. Txawm hais tias nws pheej yig rau cov duab nyuaj, nws yuav muaj qhov porosity lossis tsis sib xws, txwv nws siv rau hauv cov xwm txheej hnyav. Cov qib ib txwm muaj xws li ASTM A216 WCB (cov hlau carbon) thiab ASTM A351 CF8M (cov hlau tsis xeb).
Qhov Txawv Tseem Ceeb Ntawm Forged Steel Valve thiab Cast Steel Valves
| Cov Qauv | Cov Hlau Forged Valves | Cov Hlau Casting Valves |
| Qhov Loj Ntau Yam | Me dua (DN15–DN200, ½”–8″) | Loj dua (DN50–DN1200, 2″–48″) |
| Kev Ntsuas Siab | Qib Siab Dua (Chav Kawm 800–4500) | Nruab Nrab (Chav Kawm 150–600) |
| Kub | -29°C txog 550°C | -29°C txog 425°C |
| Cov ntawv thov | Cov kav dej siab, cov chaw ua roj av | Cov tshuab muaj zog qis/nruab nrab, dej |
Kev faib tawm ntawm Valve
Cov Hlau Forged Valves
1. Cov Rooj Vag Hlau Forged (Chav Kawm 800): Tsim qauv me me rau kev rho tawm qhov siab hauv cov roj / roj systems.
2. Forged Steel Globe Valves: Kev tswj xyuas qhov ntws kom meej hauv cov pa lossis cov kev pabcuam tshuaj.
3. Cov Hlau Forged Check ValvesTiv thaiv kom tsis txhob rov qab ntws hauv cov compressors lossis cov twj (hom swing/lift).
4. Forged Steel Ball ValvesKev kaw sai hauv cov kav dej hydrocarbon Class 800.
Cov Hlau Casting Valves
1. Cov Rooj Vag Hlau Uas Ua Los Ntawm Hlau (Chav Kawm 150–300)Kev rho tawm cov kua dej ntau hauv kev kho dej.
2. Cov Hlau Cam Khwb Cia HlauKev tswj hwm kev ntws dav dav hauv HVAC cov kab ke.
3. Cov Hlau Cam Khwb Cia: Cov kev daws teeb meem pheej yig rau cov kev pabcuam tsis tseem ceeb.
Vim Li Cas Thiaj XaivChav Kawm 800 Forged Steel Valves
Chav Kawm 800 forged steel li qub tiv taus qhov siab txog li 1380 bar (20,000 psi) ntawm 38 ° C, ua rau lawv zoo tagnrho rau:
- Cov chaw tsim roj av hauv hiav txwv
- Cov kav dej kub siab
- Cov nroj tsuag ua hydrogen
Xaus lus
Cov hlau forged valvesua tau zoo hauv cov chaw muaj kev ntxhov siab vim lawv txoj kev tsim kho ruaj khov, thaum cov hlau cam khwb cia muab cov kev daws teeb meem pheej yig rau cov kab ke loj dua, qis-siab. Kev xaiv hom zoo nyob ntawm cov kev xav tau ua haujlwm, peev nyiaj, thiab cov qauv kev lag luam xws li ASME B16.34.
