Ma valve a Gulugufe a API 609: Buku Lonse Laukadaulo

Kodi Valve ya Gulugufe ya API 609 ndi Chiyani?

Ma Vavu a Gulugufe a API 609Ndi ma valve a mafakitale opangidwa motsatira miyezo ya American Petroleum Institute (API). Amapereka kutseka kwapadera, kukana dzimbiri, komanso kudalirika kwa kuthamanga kwa mafuta, gasi, mankhwala, ndi petrochemical mapaipi. Ma valve a gulugufe amenewa ogwira ntchito bwino amakwaniritsa miyezo yapadziko lonse lapansi yotetezeka komanso yogwira ntchito bwino.

Kumvetsetsa Miyezo ya API 609

API 609 ndiye muyezo wopangira ma valve a gulugufe aku America opangidwa ndiBungwe la Mafuta ku AmericaDzina lake lonse ndi “Ma Vavu a Gulugufe: Mtundu Wachiwiri Wopindika, Wonyamula ndi Wopanda Chidebe". Mtundu waposachedwa kwambiri pakadali pano ndi wa 2021."

Mtundu waposachedwa wa API 609 ndi ‌API 609-2021 (Kope la 8), lomwe limasintha miyezo ya kapangidwe ka valavu ya gulugufe, limakulitsa zofunikira za mavalavu a gulugufe a double flange, lug ndi wafer, ndikuwonjezera magawo a mavalavu a gulugufe a butt-weld.
Zomwe zili mu zosintha zachizolowezi

•Valavu ya gulugufe ya Butt WeldMtundu wa 2021 umawonjezera zofunikira pakupanga ma valve a gulugufe opangidwa ndi butt-weld pamaziko oyamba, zomwe zimapangitsa kuti zikhale zosavuta kugwiritsa ntchito njira zolumikizira ma valve a gulugufe.

‌•Kusintha kwa mawu aukadaulo: Mafotokozedwe ena aukadaulo akonzedwa bwino malinga ndi machitidwe amakampani, koma tsatanetsatane waukadaulowo sunawululidwe mwatsatanetsatane muzidziwitso za anthu onse.

Zomwe zili mu muyezo wa API 609 zimaphatikizapo mapangidwe a ma valavu a gulugufe okhala ndi flanges ziwiri, mtundu wa lug, ndi wafer. Muyezo uwu umatanthauzira:

1. Zofunikira pa Kapangidwe:Kukonza mphamvu zamadzimadzi kuti pakhale kukana kochepa kwa madzi ndi kuwongolera molondola.

2. Zipangizo ndi Kupanga: Mafotokozedwe a matupi a ma valavu, ma disc (mbale za gulugufe), ma tsinde, ndi zisindikizo.

3. Ma Protocol Oyesera:Mayeso okakamiza a kuthamanga, kutseka, ndi kuyenda kwa madzi kuti atsimikizire ubwino.

4. Malangizo Osamalira:Njira zowunikira, kudzola mafuta, ndi kukonza.

Momwe Ma Valves a Gulugufe Amagwirira Ntchito

A valavu ya gulugufeDiski ya 's imazungulira 90° mozungulira mzere wake kuti ilamulire kayendedwe kake. Makhalidwe ofunikira:

•Malo Otseguka: Chimbale chofanana ndi kuyenda (kutsika pang'ono kwa mphamvu).

•Malo Otsekedwa: Disiki yolunjika ku kayendedwe ka madzi (kutseka mwamphamvu ngati thovu).

•Kuchitapo kanthu: Imagwiritsa ntchito zogwirira zamanja, zida zoyendetsera, kapena makina odziyimira okha (pneumatic/electric).

Zigawo Zazikulu za Ma Valves a Gulugufe

1. Thupi la Vavu

Kapangidwe kakang'ono ka cylindrical; kamapezeka mumitundu ya wafer, lug, kapena flange.

2. Chimbale (Mbale)

Mbale yopyapyala, yozungulira (yomwe ndi chitsulo chosapanga dzimbiri) yowongolera kayendedwe ka madzi.

3. Tsinde

Chimbale cholumikizira shaft champhamvu kwambiri ku actuator.

4. Mphete ya Mpando (Yotseka)

Mipando ya EPDM, PTFE, kapena yachitsulo kuti isatuluke konse.

5. Woyambitsa

Ma drive amanja, a pneumatic, hydraulic, kapena amagetsi.

Mitundu ya Ma Vavu a Gulugufe

By Eccentricity

Valavu ya Gulugufe Yozungulira: Madzi/mpweya wochepa mphamvu.

Valavu ya Gulugufe Yokha Yopanda ChidwiKuchepa kwa kukangana; koyenera kwambiri pa chakudya/mankhwala.

Valavu ya Gulugufe Yachiwiri Yozungulira: Yotsekedwa ndi chitsulo; imagwirira nthunzi pa kutentha kwa 425°C.

Valavu ya Gulugufe Yozungulira Katatu: Kutaya madzi konse; imapirira kutentha kwa 700°C/25MPa.

Ndi Mtundu Wolumikizira

Valavu ya Gulugufe Wafer:Yaing'ono, yotsika mtengo.

Valavu ya Gulugufe:Kugwira ntchito kwapakati pa mzere.

Valavu ya Gulugufe Yopindika:Kukhazikika kwa kuthamanga kwambiri.

Ndi Zinthu Zofunika

Valavu ya Gulugufe Yosapanga Chitsulo:Yosagwira dzimbiri chifukwa cha mankhwala.

Valavu ya Gulugufe ya Chitsulo cha Mpweya:Thupi la valavu lopangidwa ndi Carbon Steel, Valve Disc ikhoza kukhala WCB, CF8, CF8M, CF3, CF3M.

Valavu ya Gulugufe ya Chitsulo:Thupi la valavu ndi Ductile Iron kapena Cast Iron, Valve Disc idzakhala Ductile Iron+Ni, CF8, CF8M, CF3, CF3M.

Vavu ya Gulugufe Yapamwamba Kwambiri:Mpando wa valavu ndi RPTFE/PTFE, ndipo mpando wa valavu umayikidwa pa mbale ya valavu ndipo ukhoza kuchotsedwa ndikusinthidwa pa payipi, nthawi zonse umakhala wofanana ndi Double Eccentric kapena Triple eccentric.

Ma Vavu a Gulugufe vs. Ma Vavu a Mpira vs. Ma Vavu a Chipata

Kusankha Valavu Yoyenera ya Gulugufe

• Zowononga:Valavu ya gulugufe yachitsulo chosapanga dzimbiri yokhala ndi PTFE.

•Kutentha Kwambiri/Kupanikizika:Valavu ya gulugufe ya API 609 yokhala ndi mawonekedwe atatu, yokhala ndi mipando yachitsulo.

•Kugwiritsa Ntchito Ukhondo:Vavu ya gulugufe yopukutidwa yokhala ndi zisindikizo za EPDM.

•Zokha zokha:Zoyendetsa zamagetsi/mpweya.

Mapulogalamu a Makampani

•Mafuta/Gasi:Ma valve a gulugufe a API 609 m'mapaipi oyeretsera.

•Malo Opangira Mphamvu:Ma valve ogwira ntchito bwino kwambiri owongolera nthunzi.

•Kuchiza Madzi:Ma valve a gulugufe a Wafer m'malo opopera madzi.

•Kukumba:Mapangidwe osatha kuvala onyamulira matope.
