Kusiyana Pakati pa Valve ya Pulagi ndi Valve ya Mpira

Valavu ya Pulagi vs.Valavu ya Mpira: Magwiritsidwe Ntchito & Milandu Yogwiritsira Ntchito

Chifukwa cha kuphweka kwawo komanso kulimba kwake, ma valve a mpira ndima valve olumikizirazonsezi zimagwiritsidwa ntchito kwambiri m'njira zosiyanasiyana zopachikira mapaipi.

Ndi kapangidwe kake ka ma doko onse komwe kamalola kuti media iyende bwino, ma plug valve nthawi zambiri amagwiritsidwa ntchito kunyamula matope, kuphatikizapo matope ndi zimbudzi. Amaperekanso shutoff yolimba ngati thovu pamadzimadzi, gasi ndi nthunzi. Ngati atalimbikitsidwa, mphamvu zawo zotseka kale zimatha kupereka chisindikizo cholimba ngati madzi akutuluka. Kusavuta kwawo komanso makhalidwe awo oletsa dzimbiri zimapangitsa kuti zikhale zodalirika kwambiri pa ntchito zomwe kutseka mwachangu komanso kolimba ndikofunikira.

Ma valve a mpira amaperekanso njira yozimitsira madzi m'madzi monga mpweya, gasi, nthunzi, hydrocarbon, ndi zina zotero. Ma valve a mpira omwe amagwiritsidwa ntchito pochiza kuthamanga kwambiri komanso kutentha kwambiri amapezeka m'mizere ya gasi, m'mafakitale amafuta osakonzedwa bwino, m'mafamu a matanki, m'malo oyeretsera mafuta komanso m'malo ogwiritsira ntchito makina odzipangira okha. Ma valve a mpira omwe ali ndi mphamvu zambiri amapezeka m'malo osungiramo madzi pansi pa nthaka komanso pansi pa nyanja. Amatchukanso m'malo ogwiritsira ntchito ukhondo monga zamankhwala, zamankhwala, zamankhwala, zamankhwala, kupanga mowa komanso kukonza chakudya ndi zakumwa.

Ndi Mtundu Uti wa Valve Woyenera Kugwiritsa Ntchito Kwanu?

Ntchito ndi kapangidwe ka ma plug ndi ma ball valve — ndi kusiyana pakati pawo — n'zosavuta, koma nthawi zonse zimathandiza kulankhula ndi katswiri yemwe angakutsogolereni njira yoyenera.

Mwachidule, ngati mukufuna valavu yoyatsa/kuzima kuti mugwiritse ntchito mphamvu zochepa mpaka zochepa, valavu yolumikizira imakupatsani chisindikizo chofulumira komanso cholimba. Pa ntchito zochepa mpaka zapamwamba (makamaka zomwe kuchepetsa mphamvu ndikofunikira), mavalavu a mpira ndi njira yodalirika komanso yosavuta kugwiritsa ntchito. Pali zosiyana pazochitika zonse, koma kudziwa bwino makhalidwe awo ndi momwe amagwiritsidwira ntchito ndi malo abwino oyambira.
