Valavu Yoyenderana ndi Chipata Chotsetsereka: Chitsogozo Chomaliza cha Zinthu, Mitundu ndi Mapulogalamu

Kodi Valavu ya Chipata Chofanana ndi Slide ndi Chiyani?

Valavu ya Parallel Slide Gate ndi valavu yotsetsereka yomwe imalamulira kutseguka/kutseka kudzera mu ma disc a parallel gate. Chotsekera chake (gate disc) chili ndi malo opukutidwa bwino komanso osalala omwe amagwirizana bwino ndi mpando, makamaka omwe amagwiritsidwa ntchito kutseka kapena kulumikiza njira yolumikizirana.

Mfundo Yogwirira Ntchito

Valavu yolowera yofanana ndi slide imagwiritsa ntchito kapangidwe ka ma disc awiri ofanana. Makina oyendetsera amasuntha chipata molunjika kuti atsegule/tseke njira yamadzimadzi. Chipatacho chili ndi bore yofanana ndi m'mimba mwake wamkati wa chitoliro. Kuzungulira gudumu lamanja kapena kuyambitsa actuator kumakweza/kutsitsa tsinde ndi chipata. Bore ya chipata ikagwirizana ndi payipi, madzi amatuluka (valavu imatseguka). Chipata chikatseka njira yamadzimadzi (bore yobwerera m'chipinda cha valavu), valavu imatseka.

Zigawo Zofunika Kwambiri za Ma Valves a Parallel Slide Gate

Vavu Thupi & Chipata Disc

Thupi lake limapangidwa ndi chitsulo cha kaboni, chitsulo chosapanga dzimbiri, ndi zina zotero, ndipo limasunga ma disc a chipata chofanana. Kapangidwe ka ma disc awiri kamawonjezera kutseka. Kusuntha kwa ma disc oyima kumawongolera kuyenda.

Kumanga Tsinde ndi Kusindikiza

Tsinde (chitsulo chosapanga dzimbiri/chitsulo chosapanga dzimbiri) limalumikizana ndi chipata kudzera mu ulusi. Zigawo zotsekera zimaphatikizapo mipando yolimba ya aloyi, PTFE, kapena mphete za graphite zomwe zimaonetsetsa kuti zitsekeredwe mbali zonse ziwiri.

Njira Yoyendetsera

Ma actuator amatsatira miyezo ya API 6D, yothandizira kugwira ntchito ndi manja, zamagetsi, kapena pneumatic. Pali njira zina zopewera kuphulika.

Kapangidwe kosindikiza

Ili ndi mipando yoyandama yokhala ndi malo otsegulira zinthu kuti zitsekedwe mbali zonse ziwiri. Zipangizo: graphite yolimbikitsidwa, PTFE.

Zigawo Zina Zofunika Kwambiri

Yoke Sleeve: Aluminiyamu bronze imachepetsa mphamvu yogwirira ntchito.

Mphete ya Mpando: Yolumikizidwa kuti isavutike kukonza.

Ma Valves a Chipata Cholowera Mpweya Chosalowa ...

Kusiyana kwakukulu kuli mu kapangidwe kake, ntchito yake, ndi kagwiritsidwe ntchito kake. Ma valve otsegula mpweya ali ndi dzenje lochepetsera kupanikizika, kuyika ma pig, ndi chitetezo cha mipando m'mapaipi ataliatali. Ma valve otsegula mpweya sakugwirizana ndi makina otsekedwa popanda zofunikira pakuyika ma pig.

Kusiyana kwa Kapangidwe ndi Ntchito

• Kapangidwe ka Mabowo Otulukira Mpweya:

Mpweya wopumira:Bowo (lofanana ndi kukula kwake) mu diski yapansi. Lotseguka kwathunthu = bowo limagwirizana ndi mpando kuti lichepetse kuthamanga/kupanikizika.

Chopanda Mpweya:Palibe dzenje. Mzere wa mpando umaonekera pa malo otseguka.

• Chitetezo cha Chisindikizo:

Mpweya wopumira:Dzenje nthawi zonse limateteza mipando ku kuwonongeka kwa malo ozungulira mwachindunji, zomwe zimawonjezera moyo wawo.

Chopanda Mpweya:Mipando imatha kuwonongeka ikatsegulidwa; kudalirika kwake sikuchepa.

Zochitika Zogwiritsira Ntchito

Ubwino wa Kuchita Bwino

•Kuchepetsa Kupanikizika: Kumatsegula mpweya wotuluka m'mimba, kuteteza kupanikizika kwambiri kuchokera ku kukula kwa media.

•Kugwira Ntchito Moyenera: Kutsika kwa mphamvu pang'ono komanso njira yoyenda bwino (yabwino kwambiri pa mafuta osakonzedwa, gasi wachilengedwe).

•Kusamalira: Kukonza nkhumba kumachotsa mapaipi omwe asungidwa, zomwe zimachepetsa nthawi yogwira ntchito.

Makhalidwe a Kapangidwe

•Kapangidwe ka Kutseka: Zisindikizo za O-ring + mipando yoyandama yomwe yayikidwa kale imalola kutseka mbali zonse ziwiri. Mphamvu yogwiritsira ntchito ndi yotsika ndi 50% kuposa ma valve wamba.

•Kapangidwe ka Kulongedza: Kulongedza kodzitsekera kumafuna kusintha kochepa. Kugwira ntchito mopepuka komanso kutseka kodalirika. Kulowetsa mafuta othandizira kumaonetsetsa kuti palibe kutuluka kwa madzi.

•Kapangidwe ka Njira Yoyendera: Njira yoyenda yolunjika yokhala ndi mabowo athunthu imachepetsa kutayika kwa mphamvu. Imathandizira kukwera kwa mapaipi.

•Chitetezo: Kapangidwe kotsekedwa mokwanira kuti kagwiritsidwe ntchito nthawi zonse.

•Chipangizo Chothandizira Kupanikizika: Chimaletsa kuwonongeka kwa mkati mwa kupanikizika kwambiri.

•Gulu:

Ndi Drive:Manja, Pneumatic, Magetsi.

Ndi Ntchito:Malo Opumulirako, Osapumulirako, Malo Opaka Mafuta, Mapaipi, Gasi.

Minda Yofunsira

→Mafuta ndi Gasi: Ma valve akuluakulu otumizira mpweya wosaphika/wachilengedwe (mpaka 15.0MPa). Amagwiritsidwa ntchito mu makina opopera ndi kusungiramo. Amagwirizana ndi API 6D.

→Makampani Opanga Mankhwala: Amalamulira zinthu zowononga (ma acid, slurries) pogwiritsa ntchito PTFE/graphite seals.

→Makampani Opanga Mphamvu: Amayendetsa kayendedwe ka madzi ozizira/nthunzi m'mafakitale otentha, nyukiliya ndi madzi. Amawongolera kugwiritsa ntchito mphamvu moyenera.

→Maboma ndi Zachilengedwe: Amalamulira madzi otayira/mpweya m'makina oyeretsera/otulutsa madzi. Amagwiritsidwa ntchito popereka madzi/madzi otayira madzi.

→Makampani Ena: Kusamutsa zitsulo zoyera kwambiri (zitsulo), kusamutsa zinthu zoyera (mankhwala), kulamulira madzi a ukhondo (chakudya).

Ubwino ndi Zoyipa

Ubwino

1. Kukana Kuyenda Kochepa: Kapangidwe kowongoka kokhala ndi chitoliro chachifupi ≈. Kuthamanga kwakukulu.

2. Kutseka Kwabwino Kwambiri: Ma disc otseka kawiri (okhala ndi chitsulo + mipando yofewa) amatsimikizira kutsekedwa kosataya madzi. Amathandizira kusinthasintha kwa kuthamanga/kutentha.

3. Kapangidwe Kosavuta: Kupanga ndi kukonza kosavuta. Mtengo wotsika wa moyo wonse.

4. Kukana Kuvala: Mipando yolimba imawonjezera nthawi yogwira ntchito muzovala zowawa.

5. Kugwiritsa Ntchito Kwambiri: Kuyenera zinthu zosiyanasiyana (-196°C cryogenic mpaka +550°C nthunzi) - zopanda mafuta, gasi, asidi, ndi slurry.

6. Mphamvu Yochepa Yogwira Ntchito: Kugwiritsa ntchito pamanja mosavuta.

7. Kutseka Mbali Ziwiri: Chitetezo cha kutayikira kwa madzi.

Zoyipa

1. Sizoyenera Kutulutsa Madzi: Zimangofunika kuyikidwa pa ON/OFF. Kutseguka pang'ono kumawononga mipando.

2. Kusagwira bwino ntchito kwa madzi: Kusagwira bwino ntchito kwa madzi pafupifupi 50% yokha.

3. Kugwedezeka kwa Disiki: Kumakhala ndi kugwedezeka kosalekeza pamene kutseka motsutsana ndi kuyenda kwa liwiro/kuchuluka kwa mphamvu.

Malangizo Osankha

1. Kugwirizana kwa Zida: Gwirizanitsani zinthu za valavu ndi zida. Mwachitsanzo:

• Asidi/Alkalis → Chitsulo chosapanga dzimbiri / chokhala ndi PTFE.

• Madontho Osakhazikika → Disiki yokhala ndi tungsten carbide.

• Ntchito Yowunikira → Tsimikizirani kulimba kwa zinthuzo kutentha kochepa.

2. Kupanikizika ndi Kutentha: Onetsetsani kuti valavu ikukwaniritsa momwe ntchito ikuyendera:

• Kalasi 150: -29°C mpaka 425°C

• Kalasi 600: -196°C mpaka 550°C

• Kalasi 1500: -29°C mpaka 650°C

3. Mtundu wa Kapangidwe:

• Tsinde Lokwera:Kuti mupeze mwayi wochita ntchito/kunyamula nkhumba pafupipafupi.

• Tsinde Losakwera:Kwa ntchito zosachitika kawirikawiri/malo ochepa.

4. Njira Yogwirira Ntchito: Magawo Ena: TaganiziraniCv (kuchuluka kwa kayendedwe ka madzi), kalasi yotayikira, mwayi wokonza, ndi zosowa zogwirira ntchito.

• Manja: Ma valve ang'onoang'ono kapena othandizira.

• Magetsi/Maginito: Ma valve akuluakulu (DN300+).

• Malo Ophulika → Mphamvu yamagetsi ya Pneumatic/Hydraulic kapena yosaphulika.

• Ma valve amanja: Onjezani gearbox kuti mugwiritse ntchito mphamvu zambiri.
