Mavavu a globe ndi gawo lofunikira m'mafakitale ambiri

Mavavu a globe ndi gawo lofunika kwambiri m'mafakitale ambiri, omwe amapereka kuwongolera bwino kwamadzi mu mapaipi ndi machitidwe. Ma valve awa ndi osinthika ndipo amatha kugwiritsidwa ntchito m'njira zosiyanasiyana, kuwapanga kukhala chisankho chodziwika bwino pakati pa mainjiniya ndi opanga makina.

Ubwino umodzi waukulu wa ma valve a globe ndi kuthekera kwawo kuwongolera kutuluka kwamadzimadzi molondola kwambiri. Izi zimatheka pogwiritsa ntchito chimbale chochotsa chomwe chingathe kukhazikitsidwa kuti chiwongolere kuthamanga kwa valve. Chifukwa chake, ma valve a globe amagwiritsidwa ntchito nthawi zambiri komwe kumayenera kuwongolera bwino kayendedwe ka madzimadzi, monga malo opangira madzi, malo opangira mankhwala, ndi magetsi.

Kuphatikiza pa mphamvu zawo zowongolera bwino, ma valve a globe amadziwikanso chifukwa cha kulimba kwawo komanso kudalirika. Ma valve awa amapangidwa kuti athe kupirira kupanikizika kwakukulu ndi kutentha, kuwapanga kukhala oyenera kugwiritsidwa ntchito m'madera ovuta a mafakitale. Amakhalanso ocheperako pang'onopang'ono kusiyana ndi mitundu ina ya ma valve, kupereka chitetezo chochuluka ku machitidwe omwe amaikidwa.

Mavavu a Globe amapezeka mumitundu yosiyanasiyana ndi zida, kuwapanga kukhala oyenera kugwiritsidwa ntchito mosiyanasiyana. Zitha kupangidwa kuchokera ku zipangizo monga zitsulo zosapanga dzimbiri, zitsulo za carbon ndi bronze ndipo zimagwirizana ndi madzi osiyanasiyana komanso ntchito. Kuonjezera apo, ma valve a globe amatha kupangidwa ndi mitundu yosiyanasiyana yolumikizira mapeto, monga flanged, ulusi, kapena welded, kuti agwirizane ndi zofunikira za dongosolo lopatsidwa.

Pankhani ya mapangidwe, valavu yapadziko lonse lapansi imadziwika ndi mawonekedwe ake ozungulira, motero amatchedwa. Kapangidwe kameneka kamapangitsa kuti pakhale njira yoyenda bwino kudzera mu valavu, kuchepetsa kutsika kwamphamvu ndi chipwirikiti mu dongosolo. Disiki mkati mwa valavu nthawi zambiri imatsogoleredwa ndi tsinde la valve, lomwe lingathe kuchitidwa pamanja, magetsi kapena pneumatic kuti liwongolere kutuluka kwa madzi. Kukonzekera kumeneku kumapangitsa kuti valavu igwire ntchito moyenera komanso yodalirika, kuonetsetsa kuti kuthamanga kwa kayendedwe kameneko kumasungidwa nthawi zonse.

Mavavu a globe nthawi zambiri amaikidwa m'makina momwe madzi amalowera kuchokera pansi ndikutuluka kuchokera pamwamba. Kukonzekera uku kumapangitsa kuti valavu igwiritsidwe ntchito ngati chipangizo chogwedeza, kuyang'anira kuchuluka kwa kayendedwe kake mwa kusintha malo a disk. Nthawi zina, ma valve a globe amathanso kuikidwa mu kachitidwe kotsutsana ndi kayendedwe ka kayendedwe ka kayendedwe ka kayendedwe ka kayendedwe ka kayendedwe ka kayendedwe ka kayendedwe ka kayendedwe ka kayendedwe ka kayendedwe ka kayendedwe ka kayendedwe ka kayendedwe ka kayendedwe ka kayendedwe kake, ndi kutuluka kolowera pamwamba ndi kutuluka pansi, malingana ndi zofunikira za dongosolo.

Mwachidule, ma valve a globe ndi zigawo zofunika kwambiri m'mafakitale ambiri, zomwe zimalola kuwongolera bwino kwa kayendedwe ka madzi ndi ntchito yodalirika m'madera ovuta. Chifukwa cha kusinthasintha kwawo, kulimba komanso zosankha zosiyanasiyana, ma valve padziko lonse lapansi ndi chisankho chodziwika bwino pakati pa mainjiniya ndi opanga makina omwe akufuna kuonetsetsa kuti machitidwe awo akugwira ntchito moyenera, motetezeka. Kaya amagwiritsidwa ntchito pochiza madzi, kukonza mankhwala, kupanga magetsi kapena ntchito zina, ma valve a globe amapereka mlingo wolamulira ndi wodalirika womwe ndi wofunikira kwambiri kuti ntchito zamakampani zitheke.
