Pulagi Vavu vs Mpira Vavu: Kumvetsetsa Kusiyanasiyana

Pankhani yolamulira kutuluka kwa madzi mu makina a mapaipi, njira ziwiri zodziwika bwino ndi valavu ya pulagi ndivalavu ya mpira. Mitundu yonse iwiri ya ma valve imakhala ndi zolinga zofanana koma imakhala ndi mawonekedwe omwe amawapangitsa kukhala oyenera kugwiritsidwa ntchito mosiyanasiyana. Kumvetsetsa kusiyana pakati pa valavu ya pulagi ndi valavu ya mpira kungakuthandizeni kupanga chisankho choyenera pa zosowa zanu zenizeni.

Ma Valves Design ndi Ntchito

A valavu ya pulagiimakhala ndi pulagi ya cylindrical kapena tapered yomwe imalowa mumpando wofananira mkati mwa thupi la valve. Pulagi imatha kuzunguliridwa kuti itsegule kapena kutseka njira yolowera, kuti igwire ntchito mwachangu komanso mophweka. Kapangidwe kameneka kamakhala kothandiza makamaka pamapulogalamu omwe amafunikira kuwongolera pafupipafupi.

Mosiyana ndi izi, valavu ya mpira imagwiritsa ntchito diski yozungulira (mpira) yokhala ndi dzenje pakati pake. Vavu ikatsegulidwa, dzenjelo limagwirizana ndi njira yolowera, zomwe zimapangitsa kuti madzi azitha kudutsa. Akatsekedwa, mpirawo umazungulira kuti uletse kuyenda. Ma valve a mpira amadziwika chifukwa cha kusindikiza kwawo kolimba ndipo nthawi zambiri amagwiritsidwa ntchito ngati kupewa kutayikira ndikofunikira.

Makhalidwe Akuyenda kwa Vavu

Ma valve onse a plug ndi mpira amapereka njira yabwino yoyendetsera bwino, koma amasiyana mumayendedwe awo. Ma valve omangika nthawi zambiri amapereka milingo yowongoka, kuwapangitsa kukhala oyenera kugwiritsa ntchito kugunda. Komabe, amatha kukumana ndi madontho apamwamba kwambiri poyerekeza ndi ma valve a mpira, omwe amapereka kutuluka kosalekeza pamene akutsegula kwathunthu.

Mapulogalamu a valve

Mavavu omangira amagwiritsidwa ntchito kwambiri popanga ma slurries, mpweya, ndi zakumwa, makamaka m'makampani amafuta ndi gasi. Ma valve a mpira, kumbali ina, amagwiritsidwa ntchito kwambiri m'makina operekera madzi, kukonza mankhwala, ndi ntchito za HVAC chifukwa cha kudalirika kwawo komanso kugwiritsa ntchito mosavuta.

Mapeto

Mwachidule, kusankha pakati pa valavu ya pulagi ndi valavu ya mpira kumadalira zofunikira za ntchito yanu. Ngakhale ma valve onsewa amapereka ubwino wapadera, kumvetsetsa kusiyana kwawo pakupanga, kugwira ntchito, ndi kayendedwe kake kudzakuthandizani kusankha valavu yoyenera kuti mugwire bwino ntchito.
