Mfundo ya valavu ya mpira wa pneumatic

Mfundo ya valavu ya mpira wa pneumatic? Mfundo yogwira ntchito ya valavu ya mpira wa pneumatic ndiyo kupanga valavu kuyenda kapena kutsekeka pozungulira pakati pa valve. Valavu ya mpira wa pneumatic ndiyosavuta kusintha komanso yaying'ono kukula. Thupi la valve ya mpira likhoza kukhala lophatikizana kapena lophatikizidwa. Mavavu a mpira wa pneumatic amagawika kwambiri kukhala mavavu a mpira wa pneumatic, pneumatic-njira zitatu mpira mavavu, mavavu a mpira otsekedwa ndi pneumatic, ma valve a mpira okhala ndi fulorini ndi zinthu zina. Itha kupangidwa kukhala mainchesi akulu, osindikiza bwino, mawonekedwe osavuta, komanso kukonza bwino. Malo osindikizira ndi ozungulira nthawi zambiri amakhala otsekedwa, omwe si ophweka kuti awonongeke ndi sing'anga, ndipo amagwiritsidwa ntchito m'mafakitale ambiri.

Mfundo ya dongosolo pneumatic mpira valve

Valve ya mpira wa pneumatic palokha imakhala ndi mawonekedwe ophatikizika ndipo ndi osavuta kugwiritsa ntchito ndikuwongolera. Ndi oyenera ntchito wamba TV monga madzi, zosungunulira, zidulo ndi gasi, komanso ndi oyenera atolankhani ndi zinthu zovuta ntchito, monga mpweya, hydrogen peroxide, methane ndi ethylene. Thupi la valve ya mpira likhoza kukhala lophatikizana kapena lophatikizidwa.

Ubwino wa valavu ya mpira wa pneumatic

Mpweya valavu mpira ndi valavu ya pulagi ndi ya mtundu womwewo wa valavu, gawo lake lotsekera ndilo gawo, ndipo gawolo limazungulira kuzungulira pakati pa thupi la valve kuti likwaniritse kutsegula ndi kutseka.

Mavavu a mpira wa pneumatic amagwiritsidwa ntchito makamaka mu payipi kuti adule liwiro, kugawa ndikusintha njira yolowera pakati. Vavu ya mpira ndi mtundu watsopano wa valavu, Ubwino wa valavu ya mpira wa pneumatic:

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. Kuchita bwino kosindikiza. Pulasitiki imagwiritsidwa ntchito kwambiri ngati chosindikizira pamwamba pa mavavu a mpira, yomwe imakhala ndi ntchito yabwino yosindikiza ndipo imagwiritsidwa ntchito kwambiri pamakina opumulira.
4. Ndiosavuta kugwiritsa ntchito, kutsegulira ndi kutseka mwachangu, ndikuzungulira 90 ° kuchokera kutseguka kwathunthu mpaka kutsekedwa kwathunthu, komwe ndikosavuta kuwongolera mtunda wautali.
5. Kukonza kosavuta, kapangidwe ka valavu ya mpira wa pneumatic ndi yosavuta, mphete yosindikizira nthawi zambiri imasunthika, ndipo ndiyosavuta kusokoneza ndikuyika m'malo.
6. Mukatsegulidwa kwathunthu kapena kutsekedwa kwathunthu, malo osindikizira a mpira ndi mpando wa valve amasiyanitsidwa ndi sing'anga, ndipo pamene sing'anga ikudutsa, sichidzayambitsa kukokoloka kwa valve yosindikiza pamwamba.
7. Kuchuluka kwa ntchito ndi yotakata, m'mimba mwake ndi yaying'ono ngati mamilimita angapo, yaikulu ngati mamita angapo, ndipo ingagwiritsidwe ntchito kuchokera ku vacuum yapamwamba mpaka kuthamanga kwambiri.
8. Chifukwa gwero lamphamvu la valavu mpira ndi mpweya, kupanikizika nthawi zambiri ndi 0.4-0.7MPa. Ngati valavu ya mpira wa pneumatic ikutha, poyerekeza ndi hydraulic ndi magetsi, mpweya ukhoza kutulutsidwa mwachindunji.
9. Poyerekeza ndi mavavu ozungulira amanja ndi turbine, mavavu a mpira wa pneumatic amatha kukhazikitsidwa ndi mainchesi akulu (mavavu amanja ndi ma turbine ozungulira mpira nthawi zambiri amakhala pansi pa DN300, ndipo mavavu ampneumatic amatha kufika mainchesi akulu.)
