Waa maxay Bellow Seal Globe Valve: Hagaha kama dambaysta ah

Fahamka Bellow Seal Globe Valves

Ashaabada globe valvewaa waalka xidhid gaar ah oo loogu talagalay in lagu baabi'iyo daadinta stem ee codsiyada muhiimka ah. Si ka duwan valves-ka caamada ah ee xirxiran, waxay isticmaashaa isku dhafka birta ah ee lagu alxanayo jirridda jireed iyo waalka labadaba, taasoo abuureysa shaabad hermetic ah. Naqshadani waxay lama huraan u tahay maaraynta sunta, daxalka, ama warbaahinta nadiifka ah ee qiiqa ka baxsan aan la aqbali karin.

Qaybaha muhiimka ah ee Bellow Seal Globe Valves

1. Golaha Bellows

• Qalab:Birta aan daahin (SS316/316L), Inconel 625, ama Hastelloy C276
• Naqshad:Isku-xidhka isku-xidhka badan (8-12 lakab) ee 10,000+ cimri dherer wareeg ah
• Shaqada:Cadaadis/ kordhiyaa inta lagu jiro hawlgalka waalka iyadoo la ilaalinayo daacadnimada shaabadda

2. Jirka Valve

• Qiimaynta Cadaadiska:Fasalka 150 ilaa 2500 (ANSI/ASME B16.34)
• Dhammaadka Xiriirinta:Flanged (RF/RTJ), alxanka godka, ama dabada
• Heerkulka Heerkulka:-196°C ilaa 550°C (cryogenic ilaa kulayl sare)

3. Jirrid & Disc

• Isku dhafka stem-disc-ka ee been abuurka ah ee isku toosinta
• Adkeynta dusha sare (daahan Stelite 6) ee caabbinta abrasion

4. Shaabadda Sare (kaabta)

• Xirmooyinka garaafyada ee giraangiraha ka hooseeya sariiraha sida guul-daro-ammaan

Sidee u Shaqeeyaa Qalabka Shaabadda ee Bellow Seal Globe Valve

Tallaabada 1: Furitaanka Valve-ka

Marka giraangiraha gacantu u wareego dhanka saacada:

• Jirriddu kor ayey u kacdaa, oo saxanka ka qaadaya fadhiga
• Bellows waxay isku cadaadiyaa axially, iyagoo ilaalinaya daacadnimada

Tallaabada 2: Xiritaanka Valve-ka

Saacado wareeg ah:

• Jirridu waxay xoog ku kala saartaa kursiga, joojinta socodka
• Hooska ayaa ku fidsan dhererka asalka ah

Tallaabada 3: Kahortagga daadinta

Tallaabo labanlaab ah oo xidhidh:

• Shaabadda aasaasiga ah: Bellows waxay xannibaysaa jidka daadinta stem
• Shaabadda labaad: Xirmooyinka garaafka (API 622 waafaqsan)

Faa'iidooyinka ka sarreeya Valves Standard Globe

Codsiyada Warshadaha

1. Habaynta Kiimikada

• Dhirta Chlor-alkali (kakoonka gaasta koloriin)
• Soo saarista Pharmaceutical API

2. Saliid & Gaas

• Unugyada alkylation HF
• wareejinta cryogenic ee LNG (-162°C)

3. Korontada

Shuruudaha Xulashada

1. Nooca Hooska

• Jaleecada been abuurka ah:Cadaadis sare (ASME Class 1500+)
• Gawaarida alxanka leh:Warbaahin qudhuntay (dhamays koronto leh)

2. Tilmaamaha socodka

• Boqolkiiba siman vs. socodka tooska ah ee codsiyada xakamaynta

3. Shahaadooyinka

• NACE MR0175 ee adeega dhanaan
• PED 2014/68/EU ee suuqyada Yurub

Soosaarayaasha Shiinaha Bellow Valve ee ugu sarreeya

Soosaarayaasha Shiinaha sida NSW Valve Manufacturer ayaa bixiya:

• API 602/BS 1873 nashqadaha waafaqsan
• 30% kaydinta kharashka vs. sumadaha Yurub
• Tijaabada caaga ah (helium leak test)

Hababka ugu Wanaagsan ee Dayactirka

• Kormeerka sanlaha ee jeexjeexyada daalka
• Saliid stem oo leh dufan heerkul sare leh
• Ka fogow qulqulka xad dhaafka ah (ugu badnaan 50 Nm ee valves DN50)
