Valavu ya Pulagi vs Valavu ya Mpira: Kumvetsetsa Kusiyana

Ponena za kuwongolera kuyenda kwa madzi m'mapaipi, njira ziwiri zodziwika bwino ndi valavu yolumikizira ndivalavu ya mpiraMitundu yonse iwiri ya ma valve imagwira ntchito zofanana koma ili ndi makhalidwe osiyana omwe amawapangitsa kukhala oyenera kugwiritsidwa ntchito mosiyanasiyana. Kumvetsetsa kusiyana pakati pa valavu yolumikizira ndi valavu yolumikizira kungakuthandizeni kupanga chisankho chodziwikiratu malinga ndi zosowa zanu.

Kapangidwe ndi Kugwira Ntchito kwa Ma Valves

A valavu yolumikiziraIli ndi pulagi yozungulira kapena yopapatiza yomwe imalowa mu mpando wofanana mkati mwa thupi la valavu. Pulagiyo imatha kuzunguliridwa kuti itsegule kapena kutseka njira yoyendera, zomwe zimapangitsa kuti igwire ntchito mwachangu komanso mosavuta. Kapangidwe kameneka ndi kopindulitsa makamaka pakugwiritsa ntchito komwe kumafuna kulamulira nthawi zonse.

Mosiyana ndi zimenezi, valavu ya mpira imagwiritsa ntchito diski yozungulira (mpira) yokhala ndi dzenje pakati pake. Vavu ikatsegulidwa, dzenjelo limagwirizana ndi njira yolowera madzi, zomwe zimathandiza kuti madzi azidutsa. Ikatsekedwa, mpirawo umazungulira kuti utseke madziwo. Mavalavu a mpira amadziwika kuti ndi olimba kwambiri ndipo nthawi zambiri amagwiritsidwa ntchito pamene kupewa kutuluka kwa madzi ndikofunikira.

Makhalidwe Oyendera Valavu

Ma valve onse a pulagi ndi mpira amapereka mphamvu yabwino kwambiri yoyendetsera kayendedwe ka madzi, koma amasiyana mu mawonekedwe awo oyendetsera madzi. Ma valve a pulagi nthawi zambiri amapereka mphamvu yoyendetsera madzi yolunjika bwino, zomwe zimapangitsa kuti akhale oyenera kugwiritsa ntchito pobowola madzi. Komabe, amatha kutsika kwambiri mphamvu poyerekeza ndi ma valve a mpira, omwe amapereka mphamvu yoyendetsera madzi yosasunthika akatsegulidwa kwathunthu.

Mapulogalamu a Vavu

Ma valve olumikizira amagwiritsidwa ntchito kwambiri pazinthu zokhudzana ndi matope, 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 kugwiritsa ntchito HVAC chifukwa chodalirika komanso kugwiritsa ntchito mosavuta.

Mapeto

Mwachidule, kusankha pakati pa valavu yolumikizira ndi valavu ya mpira kumadalira zofunikira za pulogalamu yanu. Ngakhale mavalavu onsewa ali ndi ubwino wapadera, kumvetsetsa kusiyana kwawo pa kapangidwe, kagwiritsidwe ntchito, ndi makhalidwe a kayendedwe ka madzi kudzakuthandizani kusankha valavu yoyenera kuti igwire bwino ntchito.
