Vavu ya pulasitiki ya pulasitiki idasinthika kuchokera ku valavu ya pulagi.Gawo lake lotsegula ndi lotseka ndi gawo, lomwe limagwiritsa ntchito gawoli kuti lizizungulira madigiri a 90 mozungulira tsinde la valve kuti likwaniritse cholinga chotsegula ndi kutseka.Valavu ya mpira wa pulasitiki ndiyoyenera kutsata njira yoyendera ndi sing'anga yowononga.Malinga ndi zipangizo zosiyanasiyana, kutentha ntchito ndi PVC 0 ℃ ~ 50 ℃, C-Zithunzi za PVC0℃～90℃, PP -20℃～100℃, PVDF -20℃～100℃ .Vavu ya mpira wa pulasitiki imakhala ndi kukana kwa dzimbiri.Mphete yosindikiza imatenga EPDM ndi FKM;imakhala ndi kukana kwabwino kwa dzimbiri ndipo imatalikitsa moyo wautumiki.Kusinthasintha kosinthasintha komanso kosavuta kugwiritsa ntchito.Valavu ya mpira wa pulasitiki Chophatikizika cha mpira chimakhala ndi malo ochepa otayikira, mphamvu zambiri, ndipo valavu yamtundu wolumikizira ndiyosavuta kusonkhanitsa ndi kupasuka.

Valavu ya pulasitiki ya pulasitiki siyosavuta kupanga, yabwino pakusindikiza, komanso kukula kwake yaying'ono, kulemera kwake, kutsika kwa zinthu zakuthupi, kakulidwe kakang'ono kakuyika, ndi torque yaying'ono yoyendetsa mkati mwamtundu wina wamtundu wina.Ndizosavuta kugwiritsa ntchito komanso zosavuta kukwaniritsa kutsegulira ndi kutseka mwachangu.Imodzi mwa mitundu ya ma valve yomwe ikukula kwambiri m'zaka khumi zapitazi.Makamaka m’maiko otukuka monga United States, Japan, Germany, France, Italy, West, ndi Britain, kugwiritsiridwa ntchito kwa ma valve a mpira n’kokulirakulira, ndipo mitundu ndi kuchuluka kwake kogwiritsiridwa ntchito kukukulirakulirabe.

Mfundo yogwirira ntchito ya valavu ya mpira wa pulasitiki ndikupangitsa kuti valavu isatsekeke kapena kutsekedwa pozungulira tsinde la valve.Chosinthiracho chimakhala chonyamula, chaching'ono, chodalirika pakusindikiza, chosavuta pamapangidwe komanso chosavuta pakukonza.Malo osindikizira ndi ozungulira nthawi zambiri amakhala otsekedwa ndipo sawonongeka mosavuta ndi sing'anga.Amagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana.

Vavu ya mpira ndi mtundu watsopano wavalavuzomwe zakhala zikugwiritsidwa ntchito kwambiri m’zaka zaposachedwapa.Ili ndi zabwino izi:

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

2. Mapangidwe osavuta, kukula kochepa ndi kulemera kochepa.

3. Ndi yolimba komanso yodalirika.Pakalipano, zinthu zosindikizira za valve ya mpira zimagwiritsidwa ntchito kwambiri m'mapulasitiki omwe ali ndi ntchito yabwino yosindikiza, ndipo amagwiritsidwanso ntchito kwambiri m'makina a vacuum.

4. Kuchita bwino, kutsegula mofulumira ndi kutseka, kumangofunika kuzungulira 90 ° kuchokera kutseguka kwathunthu mpaka kutsekedwa kwathunthu, komwe kuli kosavuta kulamulira kutali.

5. Yabwino yokonza, yosavuta dongosolo lavalavu ya mpira, mphete yosindikizirayo nthawi zambiri imasunthika, ndiyosavuta kuichotsa ndikuyisintha.

6. Mukatsegulidwa kwathunthu kapena kutsekedwa kwathunthu, malo osindikizira a mpira ndi mpando wa valve amasiyanitsidwa ndi sing'anga, ndipo sing'angayo sichidzayambitsa kukokoloka kwa valve yosindikiza pamwamba pamene sing'anga ikudutsa.

7. Ili ndi ntchito zosiyanasiyana, zokhala ndi m'mimba mwake kuyambira mamilimita angapo mpaka mamita angapo, ndipo zingagwiritsidwe ntchito kuchokera ku vacuum yapamwamba mpaka kupanikizika kwambiri.
