Mapangidwe ndi Magwiridwe Antchito a American Standard Cast Steel Globe Valves

Mapangidwe ndi Magwiridwe Antchito a American Standard Cast Steel Globe Valves

M'makina opangira mapaipi aku America, mavavu aku America omwe amapangidwa ndi zitsulo amadziwika kwambiri chifukwa cha kulimba kwawo komanso kudalirika. Valve iyi idapangidwa ndikupangidwa mosamalitsa motsatira zomwe zidakhazikitsidwa ndi American National Standards Institute (ANSI) ndi American Petroleum Institute (API). Zotsatirazi zidzapereka kusanthula kwatsatanetsatane kwa mapangidwe a ma valve a American standard cast steel globe ndi machitidwe omwe amatsatira.

Zojambulajambula

1. Kusankha kwazinthu: Mavavu aku America opangidwa ndi zitsulo zotayidwa nthawi zambiri amaponyedwa pogwiritsa ntchito ASTM A126 giredi WCB (carbon steel castings), kuonetsetsa kuti valavu ili ndi mphamvu zamakina komanso kukana dzimbiri.
2. Mapangidwe osindikizira: Mpando wa valve ndi disc zidapangidwa kuti zigwirizane bwino ndi conical kapena zozungulira zosindikizira kuti zitsimikizire kuteteza kwapakatikati kutayikira kwapakati mu malo otsekedwa ndikukwaniritsa kutseka kolimba.
3. Mapangidwe a Valve stem anti blowout: Kuteteza tsinde la valve kuti lisaphulike ndi sing'anga panthawi yothamanga kwambiri, valavu yachitsulo yaku America yopangidwa ndi zitsulo zotayirira imapangidwa ndi chipangizo choletsa kuphulika, chomwe chimapangitsa chitetezo cha valve.
4. Kukonzekera kwachitetezo chamoto: Malinga ndi API 607 ​​chitetezo chamoto, ma valve ena a American standard cast cast steel globe amapangidwa ndi zida zolimbana ndi moto, zomwe zimatha kukhala ndi luso losindikiza ngakhale pakakhala moto, kuonetsetsa chitetezo cha dongosolo.
5. Chisindikizo cha tsinde la valve: Chigawo chosindikizira cha valve chosinthika chimagwiritsidwa ntchito, chomwe chimatsimikizira kugundana kochepa panthawi yotsegula ndi kutseka, komanso kumakhala kosavuta kusunga ndi kusintha.
6. Kugwira ntchito pamanja: Kuti zitheke kugwira ntchito pamanja, mavavu a American standard cast cast steel globe nthawi zambiri amakhala ndi gudumu lamanja, ndipo kukula ndi kapangidwe kamphamvu ka gudumu lamanja kumakwaniritsa zofunikira za ANSI kuti wogwiritsa ntchitoyo azigwiritsa ntchito mosavuta.

Miyezo yamachitidwe

1. Kupanikizika: Ma valve a American standard cast steel globe amaikidwa molingana ndi miyezo yoyenera monga ANSI / ASME B16.34, monga Class 150 ndi Class 300, kuti awonetsetse kuti akugwira ntchito motetezeka pansi pa zovuta zosiyanasiyana.
2. Kutentha kwamitundu yosiyanasiyana: Malingana ndi kutentha kwa zipangizo za ASTM, ma valve a American standard cast cast steel globe ndi oyenera kumalo osiyanasiyana ogwira ntchito kuchokera kutsika mpaka kutentha kwambiri.
3. Mulingo wotayikira: Malinga ndi mulingo wotayikira wa FCI-70-2 (Factory Mutual Research), mavavu aku America opangidwa ndi zitsulo zachitsulo amapereka magawo osiyanasiyana osindikiza kuti akwaniritse zofunikira zosiyanasiyana zamafakitale.
4. Kukana kwa corrosion corrosion: Njira yopangira mankhwala ndi kutentha kwa zinthuzo zimagwirizana ndi malamulo a ASTM, kuwonetsetsa kuti valavu ikhoza kukhalabe ndi mphamvu zowononga zowonongeka muzofalitsa zowononga.
5. Chitsimikizo Chazogulitsa: Mavavu aku America opangidwa ndi zitsulo zotayidwa nthawi zambiri amafunikira ziphaso zingapo zazinthu, kuphatikiza kuyesa kukakamiza, kuyesa magwiridwe antchito, komanso kuyesa kukana moto, kuti atsimikizire kuti akukwaniritsa zofunikira pamiyezo yoyenera.

Mwachidule, ma valve a American standard cast steel globe amayang'ana kwambiri momwe angagwiritsire ntchito komanso chitetezo pamapangidwe awo, ndipo amapangidwa motsatira miyezo ya dziko la America ndi miyezo yamakampani kuti atsimikizire kugwira ntchito mokhazikika pansi pamikhalidwe yovuta kwambiri. Kaya ndi mafuta, mankhwala, gasi, kapena mafakitale ena, mavavu aku America opangidwa ndi zitsulo zotayidwa awonetsa ntchito yawo yapamwamba komanso kudalirika kwambiri. Posankha ma valve oterowo, ogwiritsa ntchito ayenera kufufuza mosamalitsa miyezo yomwe amakumana nayo komanso zofunikira zenizeni za malo ogwirira ntchito kuti atsimikizire kulondola kwa kusankha ndi ntchito yotetezeka komanso yokhazikika ya dongosolo.
