Valve ya mpirandi valavu ya pulagi ndi mtundu womwewo wa valavu, gawo lake lotsekera ndilo mpira, mpirawo umazungulira mzere wapakati wa thupi la valve kuti ukwaniritse kutseguka, kutseka valavu.Mpira valavu mu payipi makamaka ntchito kudula, kugawa ndi kusintha kayendedwe ka sing'anga.Valavu ya mpira imagwiritsidwa ntchito kwambiri m'zaka zaposachedwa ndi mtundu watsopano wa valavu ya valavu ndi valavu ya pulagi ndi mtundu womwewo wa valavu, gawo lake lotsekera ndilo mpira, mpira wozungulira pakati pa mzere wapakati wa thupi la valve kuti atembenuzire kutsegula ndi kutseka. valavu.

Valve ya mpiramu payipi makamaka ntchito kudula, kugawa ndi kusintha otaya malangizo sing'anga.Valavu ya mpira ndi mtundu watsopano wa valve womwe wagwiritsidwa ntchito kwambiri m'zaka zaposachedwa.Ili ndi zabwino izi:

1. Kukana kwamadzimadzi kumakhala kochepa, ndipo kukana kwake kumakhala kofanana ndi gawo la chitoliro chautali womwewo.

2. Mapangidwe osavuta, voliyumu yaying'ono, kulemera kopepuka.

3. Zolimba komanso zodalirika, zida zosindikizira za valve ya mpira zimagwiritsidwa ntchito kwambiri pulasitiki, kusindikiza bwino, ndipo zakhala zikugwiritsidwa ntchito kwambiri mu vacuum system.

4. Zosavuta kugwiritsa ntchito, kutsegula ndi kutseka mwamsanga, kuchokera kutseguka kwathunthu mpaka kutseka kwathunthu malinga ngati kuzungulira kwa 90 °, koyenera kulamulira kutali.

5. Kukonzekera kosavuta, mawonekedwe a valve ya mpira ndi ophweka, mphete yosindikizira nthawi zambiri imakhala yogwira ntchito, kusokoneza ndi kusinthanitsa kumakhala kosavuta.

6. Mukatsegula kwathunthu kapena kutsekedwa kwathunthu, malo osindikizira a mpira ndi mpando wa valve amasiyanitsidwa ndi sing'anga.Sing'anga ikadutsa, sichidzayambitsa kukokoloka kwa ma valve osindikiza pamwamba.

7. Yogwiritsidwa ntchito pamitundu yambiri kuchokera ku yaying'ono mpaka mamilimita angapo mpaka mamita angapo, kuchokera ku vacuum yapamwamba kupita ku kuthamanga kwambiri kungagwiritsidwe ntchito.

Valve ya mpirawakhala akugwiritsidwa ntchito kwambiri mu mafuta, makampani opanga mankhwala, kupanga magetsi, kupanga mapepala, mphamvu za atomiki, ndege, maroketi ndi madipatimenti ena, komanso moyo wa People's Daily.
