Valavu yodula imagwiritsidwa ntchito makamaka kudula kapena kulumikiza kayendedwe kapakati.mavavu a chipata, ma valve a globe, ma valve a diaphragm,mavavu a mpira, ma valve olumikizira,mavavu a gulugufe, ma valve a plunger, ma valve a pulagi ya mpira, ma valve a zida zamtundu wa singano, ndi zina zotero.

Ma valve owongolera amagwiritsidwa ntchito makamaka kusintha kayendedwe ka madzi ndi kuthamanga kwa magetsi. Kuphatikiza valavu yowongolera, valavu yotulutsa mpweya, valavu yochepetsera kuthamanga kwa madzi, ndi zina zotero.

Ma valve oyesera amagwiritsidwa ntchito kuti aletse njira yolumikizirana kuti isabwerere m'mbuyo. Amaphatikizapo ma valve oyesera amitundu yosiyanasiyana.

Ma valve a shunt amagwiritsidwa ntchito kulekanitsa, kugawa kapena kusakaniza zinthu zolumikizira. Kuphatikiza mapangidwe osiyanasiyana a ma valve ogawa ndi misampha, ndi zina zotero.

Ma valve oteteza amagwiritsidwa ntchito poteteza chitetezo pamene chotetezeracho chili ndi mphamvu yochulukirapo. Kuphatikizapo mitundu yosiyanasiyana ya ma valve oteteza.

Yogawidwa ndi magawo akuluakulu

(1) Kugawidwa ndi kukakamizidwa

Valavu yomwe mphamvu yake yogwirira ntchito ndi yotsika kuposa mphamvu yokhazikika ya mlengalenga.

Valavu yotsika ndi valavu yomwe mphamvu yake ya PN ndi yochepera 1.6MPa.

Kupanikizika kwapakati pa valavu yokakamiza ndi PN2.5 ~ 6.4MPa.

Valavu yothamanga kwambiri ili ndi mphamvu yocheperako ya PN10.0 ~ 80.0MPa.

Valavu yothamanga kwambiri ndi valavu yomwe mphamvu yake ya PN yothamanga ndi yoposa 100MPa.

(2) Yogawidwa m'magulu malinga ndi kutentha kwapakati

Valavu yotenthetsera kwambiri ndi yayikulu kuposa 450C.

Valavu yotenthetsera yapakati 120C ndi yocheperako kuposa vavu yomwe t yake ndi yochepera 450C.

Valavu yotenthetsera yachizolowezi -40C ndi yochepera t yochepera 120C.

Valavu yotsika kutentha -100C ndi yochepera t ndi yochepera 40C.

Valavu yotsika kwambiri ya kutentha t ndi yochepera -100C.

(3) Kugawa malinga ndi zinthu za thupi la valavu

Ma valve osakhala achitsulo: monga ma valve a ceramic, ma valve achitsulo chagalasi, ma valve apulasitiki.

Ma valve achitsulo: monga ma valve a mkuwa, ma valve a aluminiyamu, ma valve a lead alloy, ma valve a titanium alloy, ma valve a Monel alloy

Ma valve achitsulo chopangidwa ndi pulasitiki, ma valve achitsulo cha kaboni, ma valve achitsulo chopangidwa ndi pulasitiki, ma valve achitsulo chopangidwa ndi pulasitiki chopangidwa ndi chitsulo ...

Ma valve okhala ndi ma valve achitsulo: monga ma valve okhala ndi lead, ma valve okhala ndi pulasitiki, ndi ma valve okhala ndi enamel.

Taxonomy yonse

Njira yogawayi imagawidwa malinga ndi mfundo, ntchito ndi kapangidwe kake, ndipo pakadali pano ndiyo njira yogwiritsidwa ntchito kwambiri padziko lonse lapansi komanso m'nyumba. Valavu ya chipata chachikulu, valavu yozungulira, valavu yopopera, valavu ya zida, valavu ya plunger, valavu ya diaphragm, valavu ya pulagi, valavu ya mpira, valavu ya gulugufe, valavu yowunikira, valavu yochepetsera kupanikizika, valavu yoteteza, msampha, valavu yowongolera, valavu ya phazi, fyuluta, valavu yogwetsa, ndi zina zotero.
