Ingabe Ama-Ball Valve Angasetshenziswa Nge-Steam​: Umhlahlandlela Wokukhetha Ama-Pipeline Valve

Umhlahlandlela Wokukhetha Amavalvu Epayipi Elinomusi: Izidingo Zamavalvu Ebhola Nezinhlobo Ezivamile

Izinhlelo zomusi wezimboni zidinga ukukhethwa okuqondile kwamavalvu ukuze kuphephe futhi kusebenze kahle.Amavalvu ebholasebenza kumapayipi omusi kuphela uma uhlangabezana nezimo eziqinile: ukumelana nokushisa okuphezulu/ukucindezela, ukuvala okuqinile, kanye nemiklamo ethile yomusi (isb., ama-valve ebhola avaliwe aqinile anebhore eligcwele). Nasi incazelo yobuchwepheshe:

1. Izidingo Ezibalulekile Zama-Steam Ball Valve

◼ Izindinganiso Zezinto Nezakhiwo

• Izinto Ezishisa Kakhulu: Imizimba yamavalvu idinga insimbi ecijile ye-ASTM A216 WCB noma elinganayo.
• Umklamo Webhore Eligcwele: Uqinisekisa ukugeleza okungavinjelwe; ikilasi lokucindezela kumele lihambisane namapayipi (isb., Ikilasi 150 = 2.0MPa).

◼ Ukusebenza Kokuvala

• Izivalo Eziqinile Kuphela: Izivalo ezithambile ziyahluleka ngaphansi kwamazinga okushisa anomusi (>150°C).
• Ukujikeleza Okuzinzile: Imiklamo yebhola elintantayo/eliqinile kumele inciphise ukuguguleka.

◼ Izindlela Ezinhle Zokusebenza

• Ukufakwa Kwesiqu Esiqondile: Kuvumela ukushintsha okusheshayo okungu-90° kanye nokuvimbela ukuvuza.

◼ Izinyathelo Zokuqapha Eziyinhloko

• Izicelo: Kuhle kakhulu ekucimeni/ekulungiseni umusi ngokushesha ezitshalweni zikawoyela, zamakhemikhali kanye nezamandla.
• Imikhawulo Yokugeleza: Ijubane >40m/s libangela ukuguguleka - khetha amamodeli ngokusekelwe kumazinga okugeleza kwamapayipi.
• Ukugcinwa: Hlola izivalo njalo ngekota, susa amadiphozithi angaphakathi, bese ulandela iziqondiso ze-OEM.

2. Ama-valve amathathu aphezulu epayipi le-steam aqhathaniswa

3. Izidingo ze-Universal Steam Valve

Wonke ama-valve omusi kumele abe nalokhu okulandelayo:

1. Ukumelana Nokushisa Okuphezulu: Ukusebenza okuqhubekayo >150°C.
2. Ukuvikelwa Kokugqwala: Sebenzisa insimbi engagqwali engu-316L ukuze uthole umusi ogqwalayo.
3. Izivalo Ezingavuzi Kakhulu: Zivimbela ukulahleka kwamandla kanye nezingozi zokuphepha.

4. Izindinganiso Zokuthobela Nokukhetha

• Amakhodi Omhlaba Wonke: Landela i-API 600, i-ASME B16.34, i-DIN/EN ukuze uklame/uhlole.
• Izindlela Zokukhetha: Qondanisa imininingwane yevalvu nomfutho wombhobho, izinga lokushisa, izinga lokugeleza, kanye nemidiya.
• Ukufakwa: Namathela ku-ANSI B31.1 ukuze uthole ukuphepha kohlelo lomusi.

Isifinyezo:

Ama-valve ebhola ahambisanayo, i-Globe, kanye ne-ball ahambisanayo yizinketho eziyinhloko zamapayipi anomusi. Beka phambili ama-valve ebhola avaliwe ngokuqinile anemizimba ye-ASTM WCB, uqinisekise amazinga okugeleza (<40m/s), bese usebenzisa ukulungiswa okujwayelekile.
