Kuyambitsa ndi kugawa kwa valve yotulutsa mpweya, komanso njira yosankhidwa

Chiyambi ndi kagawo ka valavu yotulutsa mpweya, komanso njira yosankha Valavu yotulutsa mpweya ndi valavu yomwe imagwiritsidwa ntchito potulutsa mpweya ndi mpweya wina wosasunthika kuchokera ku chitoliro. Ntchito yayikulu ya valavu yotulutsa mpweya ndikuchotsa mpweya wochuluka kapena mpweya mupaipi ndikuletsa mpweya wochuluka mkati mwa payipi kuti usatseke payipi ndi kuthamanga kwa madzi kosakhazikika. M'madzi, valavu yotulutsa mpweya imathanso kutulutsa ndi kuchepetsa mpweya wa okosijeni m'madzi, kuchepetsa mphamvu yogwiritsira ntchito mpope. Mitundu ya mavavu otulutsa mpweya makamaka imaphatikizapo ma valve otulutsa pamanja, ma valve otopa okha ndi ma vacuum inspirator. Ma valve otulutsa pamanja amafunika kutsegulidwa kapena kutsekedwa pamanja ndipo ndi oyenera kutulutsa zing'onozing'ono kapena machitidwe omwe amafunikira kutulutsa pafupipafupi. Valavu yotulutsa yokha (yomwe imatchedwanso kuti valavu ya mpweya) ndi valve yomwe imatha kutulutsa mpweya. Ndioyenerera machitidwe omwe ali ndi maulendo othamanga kwambiri ndipo amafuna kupuma pafupipafupi. Ma valve otopa okha amalola kuti mpweya utuluke kuti ukhazikitse kuthamanga kwa madzi m'mapampu ndi mapaipi akayamba kugwira ntchito isanayambe komanso itatha. Nthawi zambiri amaphatikiza ziwawa zomwe zimakhudzidwa ndi madzi zomwe zimangotseka polowera. Vacuum getter ndi valavu yomwe imatha kutulutsa mpweya pansi pazovuta. Ndioyenera kumapaipi otuluka, makamaka pamalo okwera mnyumba kapena popopera mpweya, kuti azitulutsa mpweya komanso kupewa kupanga vacuum mu mapaipi. Pakusankhidwa, muyenera kuganizira zinthu izi: ntchito nthawi, sing'anga makhalidwe, otaya osiyanasiyana, tolerable kuthamanga ndi kutentha osiyanasiyana, etc. yoyenera valavu yotulutsa mpweya ayenera kusankhidwa kuti agwirizane ndi makhalidwe a sing'anga. Posankhanso zitsanzo zenizeni, muyeneranso kuganizira: kutentha kwapakati, kuthamanga, kachulukidwe, kukhuthala, etc., kuonetsetsa kuti zipangizozi zimatha kugwira ntchito moyenera komanso moyenera. Mwachidule, ma valve otulutsa mpweya amagwira ntchito yosasinthika m'makampani, zomangamanga, kukonza madzi ndi zina. Choncho, kusankha ma valve otayira oyenera ndi gawo lofunika kwambiri poonetsetsa kuti kukhazikika kwa kupanga ndi kumanga.
