Vavu ya mpira wa pulasitiki imapangidwa kuchokera ku valavu yamkuntho.Zida zake zothandizira komanso zotseka zimagwiritsidwa ntchito ngati bwalo.Mzere wa valavu yozungulira yozungulira imazungulira madigiri 90 kuti akwaniritse cholinga chotsegula ndi kutseka.Vavu ya mpira wa pulasitiki ndiyoyenera kutsata njira yopatsirana ndi media zowononga.Kutentha kwa ntchito ya kutentha kwa zinthu zosiyanasiyana PVC 0 ℃ ～ 50 ℃, C -PVC 0 ℃ ～ 90 ℃, PP -20 ℃ ～ 100 ℃, PVDF -20 ℃ ～ 100 ℃ valavu ya Plastics ℃ ili ndi kukana kwapulasitiki.Mphete yosindikiza imagwiritsa ntchito EPDM ndi FKM;ili ndi kukana kwambiri kwa dzimbiri ndikukulitsa moyo wautumiki.Kugwiritsa ntchito kosavuta komanso kosavuta.Mavavu a pulasitiki a mpira wonse amatuluka, mphamvu zambiri, komanso zosavuta kugawa mavavu olumikizira mpira.
Valve ya mpira wa pulasitiki sikuti imakhala ndi mawonekedwe osavuta komanso magwiridwe antchito abwino osindikiza, komanso imakhala ndi voliyumu yaying'ono, kulemera kwake, kugwiritsa ntchito zinthu zazing'ono, kakulidwe kakang'ono, kamphindi kakang'ono koyendetsa mum'mimba mwake, yaying'ono Imodzi mwamitundu yothamanga kwambiri zaka khumi zapitazi.Makamaka m'mayiko otukuka mafakitale monga United States, Japan, Germany, France, France, Italy, West, ndi Britain, ntchito mavavu mpira ndi lonse, ndipo ntchito mitundu ndi kuchuluka akadali kukula.
Mfundo yogwirira ntchito ya valve ya pulasitiki iyenera kutsegulidwa kapena kutsekedwa ndi tsinde la valve yozungulira.Kusinthako ndi kopepuka, kukula kwake ndi kochepa, chisindikizo ndi chodalirika, kapangidwe kake ndi kosavuta, kukonza ndi koyenera, chisindikizo ndi gawoli nthawi zambiri zimatsekedwa, sikophweka kuti ziwonongeke ndi atolankhani, ndipo zimagwiritsidwa ntchito kwambiri mafakitale osiyanasiyana.
Valve ya mpira ndi mtundu watsopano wa valve womwe wagwiritsidwa ntchito kwambiri m'zaka zaposachedwa.Ili ndi zabwino izi:
1. Kukaniza kwamadzimadzi kumakhala kochepa, ndipo ma coefficients ake otsutsa ndi ofanana ndi gawo la chitoliro cha kutalika kwake.
2. Mapangidwe osavuta, kukula kochepa, kulemera kopepuka.
3. Zolimba komanso zodalirika.Pakalipano, zipangizo zosindikizira za valve ya mpira zimagwiritsidwa ntchito kwambiri mu pulasitiki ndi kusindikiza, ndipo zakhala zikugwiritsidwa ntchito kwambiri m'machitidwe a vacuum.
4. Yosavuta kugwiritsa ntchito, kutsegula mwachangu ndi kutseka, malinga ngati mulingo wathunthu mpaka mulingo wathunthu, ingotembenuzani 90 ° kuti muthandizire kuwongolera mtunda wautali.
5. Kukonzekera kosavuta, mawonekedwe osavuta a valve valve, bwalo losindikizira nthawi zambiri limagwira ntchito, ndipo ndilosavuta kusokoneza ndikusintha.
6. Mukatsegula kapena kutsekedwa kwathunthu, chivundikiro cha chipinda ndi mpando wa valve chimasiyanitsidwa ndi sing'anga.Pamene sing'anga ikudutsa, sichidzayambitsa kukokoloka kwa chivundikiro cha valve.
7. Ntchito yogwiritsira ntchito ndi yotakata, kuyambira ang'onoang'ono mpaka mamilimita angapo mpaka mamita angapo, kuchokera ku vacuum yapamwamba mpaka kuthamanga kwambiri.
