Kodi Kuipa Kogwiritsa Ntchito Ma Globe Valves N'chiyani?

Mu kayendetsedwe ka kayendedwe ka mafakitale,valavu yapadziko lonsendi yankho lodalirika lomwe limagwiritsidwa ntchito kwambirimalamulo olondola a kayendedwe ka madzi, kugwedezandikutseka kwabwinom'machitidwe osiyanasiyana a mapaipi. Komabe, monga zipangizo zonse zamakina, ma globe valves si abwino pazochitika zonse. Ngakhale kuti ubwino wawo ndi wochuluka, kumvetsetsa zofooka zawo ndikofunikira kwa opanga makina, mainjiniya, ndi akatswiri okonza.

Ndiye, kodi vuto logwiritsa ntchito valavu yozungulira ndi lotani? Tiyeni tikambirane vuto lalikulu—ndi chifukwa chake lili lofunika—pamodzi ndi mfundo zothandizira kuti zikuthandizeni kusankha bwino valavu.

Choyamba, Kodi Valavu Yozungulira Ndi Chiyani?

Vavu yozungulira ndi mtundu wa valavu yoyenda molunjika yomwe imagwiritsa ntchito pulagi (disk) kuti iyende mmwamba ndi pansi kuti iyendetse kayendedwe kake. Dzina lake limatengedwa kuchokera ku mawonekedwe ake a thupi lozungulira. Mavavu awa amagwiritsidwa ntchito m'makina omwe amafuna:

• ①Kuthamanga pafupipafupi

• ②Kulamulira bwino kayendedwe ka madzi

• ③Kulekanitsa magawo m'mapaipi

Amagwiritsidwa ntchito kwambiri m'mafakitale amagetsi, makina a HVAC, mafakitale oyeretsera, ndi malo oyeretsera madzi.

Kuipa Kwakukulu kwa Ma Valves a Globe

Thevuto lalikuluma valve a globe ndikutsika kwa kuthamanga kwa magaziAmalowa mu payipi poyerekeza ndi mitundu ina ya ma valve monga ma gate valve kapena ma ball valve.

Chifukwa Chiyani Izi Zimachitika?

• ①Njira yoyendera madzi mu valavu yozungulira si yowongoka. Madzi ayenera kusintha njira (nthawi zambiri kupanga njira yooneka ngati Z) akamayenda m'thupi la valavu.

• ②Kusintha kumeneku kumawonjezera kugwedezeka ndi kukana, zomwe zimachepetsa kuthamanga kwa valavu pansi.

• ③Zotsatira zake n'zakuti, ma valve ozungulira sagwiritsa ntchito mphamvu zambiri ndipo si abwino kwambiri potsegula/kutseka kwathunthu komwe kumafuna kukana kochepa.

Zoyipa Zina za Ma Valves a Globe

Ngakhale kuchepa kwa kuthamanga kwa magazi ndiye vuto lalikulu, palinso zinthu zina zomwe muyenera kuganizira:

1. Mphamvu Yogwira Ntchito Yapamwamba

• ①Chifukwa cha kuyenda kwa pulagi molunjika motsutsana ndi kuthamanga kwa madzi, ma valve ozungulira nthawi zambiri amafunika mphamvu zambiri kuti atsegule kapena kutseka, makamaka pamene pali kuthamanga kwambiri.

• ②Izi zingapangitse kuti pakhale kufunika kwa ma actuator akuluakulu kapena mawilo amphamvu, zomwe zimawonjezera ndalama zoyikira komanso kufunikira kwa malo.

2. Kapangidwe Kolemera Komanso Kokulirapo

• ①Poyerekeza ndi ma valve a chipata ofanana kukula ndi kupanikizika, ma valve a globe nthawi zambiri amakhala olemera, okulirapo, komanso okwera mtengo.

• ②Izi zitha kukhala vuto m'makina okhala ndi zoletsa kulemera kapena mapangidwe ang'onoang'ono.

3. Kuvala Mpando ndi Ma disk

• ①Kugwedezeka kwa mphamvu ya throttling ndi flow turbulence kungayambitse kuwonongeka kwa mpando wa valavu ndi disk mwachangu.

• ②Kukonza kungafunike pafupipafupi, makamaka mumapulogalamu othamanga kwambiri.

4. Mtengo Wokwera wa Kukula Kofanana

• ①Ma valve a globe amakhala okwera mtengo kuposa ma valve a chipata ofanana kapena ma valve a mpira chifukwa cha kapangidwe kake ka mkati ndi mawonekedwe ake olondola owongolera kuyenda kwa madzi.

• ②Ngati kupopera sikofunikira, ndalama zowonjezera sizingakhale zoyenera.
