Vavu ya mpira wa pulasitiki: kukula kochepa, ntchito yabwino!

Thevalavu ya mpira wa pulasitikizidachokera ku valavu ya pulagi. Gawo lake lotsegula ndi lotseka ndi gawo, lomwe limagwiritsa ntchito gawoli kuti lizizungulira madigiri a 90 kuzungulira 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 ndiZithunzi za PVC0℃~50℃, C-PVC 0℃~90℃, PP -20℃~100℃, PVDF -20℃~100℃ . Vavu ya mpira wa pulasitiki imakhala ndi kukana kwa dzimbiri. Mphete yosindikiza imatenga EPDM ndi FKM; ili 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 yayikulu, 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 mwamitundu ina yodziwika bwino. 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'mayiko otukuka monga United States, Japan, Germany, France, Italy, West, ndi Britain, kugwiritsa ntchitoma valve a mpirandi zochuluka kwambiri, ndipo mitundu ndi kuchuluka kwake zomwe zimagwiritsidwa ntchito zikukulirakulirabe.

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.

 

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 coefficient yake yotsutsa ndi yofanana ndi gawo la chitoliro cha kutalika kwake.

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. Kukonzekera bwino, kapangidwe kosavuta ka valve ya mpira, mphete yosindikizira nthawi zambiri imasunthika, ndiyosavuta kusokoneza ndikusintha.

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