WCB, ASTM A216 Grade WCB he aa tlakmi carbon thir cawhnak thilri, nih a herhmi thilri sining, a tluknak fekmi le lumnak hnahnawhnak doh khawhnak hmuh khawhnak ding caah a tlarimi lumnak thlopnak kalning a tuah. A tanglei ah WCB caah a tlangpi in lumternak riantuannak kong fianternak a umYD7A1X-16 Butterfly Valvethletmi:
1. Hmasa tein lumternak
- Tinhmi: A lumnak a tlawmter i a hnu i a lum tukmi thlopnak ah a cheu lonak ding caah.
- Pehtlai in tuanmi rian: Casting pawl cu ukmi meiphu chungah tluk lumternak tiang zaangfah tein an lumter hna300–400°C (572–752°F).
- A biapimi Parameters: Lungthawhnak rate cu ah chiah a si50-100°C/suimilam (90-180°F/suimilam) lumnak tlukruang tein phawtzamh khawhnak ding caah.
2. Austenitizing (Normalizing)
- Tinhmi: Microstructure kha aa khatmi siter, rawl kung ngan le hme kha remh, le carbides kha cawh.
- Pehtlai in tuanmi rian :
- Casting pawl cu 890–940°C (1634–1724°F).
- Hi lumternak ah 25 mm (1 inch) a thuhnak ah suimilam 1-2 phase thlennak tling tein tuah khawhnak ding caah.
- A dai lomi thli ah (a tlarimi) khaan lumternak tiang lumter.
3. Lungthawhnak
- Tinhmi: A tangmi hnahnawhnak hna hloh awk, a fekmi ṭhanchoter awk le a hmete dirhmun fehter awkah.
- Pehtlai in tuanmi rian :
- A ttha tein a um hnu ah, thletmi hna cu 590–720°C (1094–1328°F).
- Hi lumnak ah 25 mm (1 inch) a thuhnak ah suimilam 1-2.
- Lungretheihnak thar a chuah lonak hnga thli ah lumter asiloah meiphu in lumtermi kha uk khawhmi rate in tuah.
4. Thlop hnu zohfelnak
- Tinhmi : ASTM A216 phunglam he aa tlak le tlak lo hngalh awk.
- Pehtlai in tuanmi rian :
- Seh thilri hneksaknak (tahchunhnak ah, hnuh khawhnak thazaang, hnuh khawhnak thazaang, harnak).
- A tlukruannak le tlamtlinlonak a um lonak hnga microstructural hlathlainak.
- Lungthawhnak thlopnak hnu ah a fekmi fehternak caah a ngan le a hme zohfelnak.
Thim khawhmi Step (Case-Specific)
- Lungretheihnak zorternak: A harmi geometries caah, a dang stress-relief cycle cu ah tuah khawh a si600–650°C (1112–1202°F) seh sernak asiloah hrennak in a tangmi hnahnawhnak hna hloh awkah.
- A ukmi lumternak: A thukmi tthencheunak caah, a tlawm deuhmi lumternak rate (tahchunhnak ah, meiphu lumternak) kha lumternak tuah lio ah hman khawh a si i cu nih cun a nemter.
Ruahchannak Biapi
- Meiphu thlihran: Decarburization hrial khawhnak dingah a tlawmmi asiloah tlawmpal a tlawmmi thli.
- Lungthawhnak aa khatmi: ±10°C tuar khawhnak nih aa khatmi phichuak hmuh khawhnak ding caah.
- Cazin: A tthatnak hngalh khawhnak caah lumternak thlopnak tahfung (caan, lum le lum lo, lumternak tlukruannak) tling tein zul khawhnak.
Hi thil kalning nih a hngalhterTWS aa khatmi hlinghro valvepumD341B1X-16WCB ah thletnak nih ASTM A216 nih a herhmi tthawnnak (≥485 MPa), tthawnnak (≥250 MPa), le sauhnak (≥22%) caah a tlinh, cu nih cun valve, pump le pipe system ah lum le hneknak hmannak caah aa tlakmi a siter.
Mah in hinTWS VALVE, chuahnak ah hmuhtonnak a ngeimirubber in a ummi aa fonhmi hlinghro valve YD37A1X, gate valve, Y-strainer sernak.
