Udindo wa valavu ya mpira wa pneumatic muzochitika zogwirira ntchito

Mavavu a Taike - ntchito za mavavu a mpira wa pneumatic pakugwira ntchito ndi ziti

Mfundo yogwirira ntchito ya valavu ya mpira wa pneumatic ndikupanga valavu kuyenda kapena kutsekeka pozungulira pakati pa valve. Valavu ya mpira wa pneumatic ndiyosavuta kusintha komanso yaying'ono kukula. Thupi la valve la mpira likhoza kuphatikizidwa kapena kuphatikizidwa. Mavavu a mpira wa pneumatic amagawika makamaka kukhala mavavu a mpira wa pneumatic, mavavu a mpira wanjira zitatu, mavavu otsekereza ma pneumatic, mavavu a mpira wa pneumatic fluorine ndi zinthu zina. Itha kupangidwa kukhala mainchesi akulu, osindikizidwa bwino, osavuta kupanga, osavuta kukonzanso, malo osindikizira ndi ozungulira nthawi zambiri amakhala otsekedwa, ndipo sikophweka kuti awonongeke ndi sing'anga, ndipo amagwiritsidwa ntchito. mu ntchito zambiri. Ma valve a Taike pneumatic mpira ndi ophatikizika komanso osavuta kugwiritsa ntchito ndikukonzanso. Iwo ali oyenera ntchito TV ambiri monga madzi, zosungunulira, zidulo ndi gasi, komanso TV ndi zinthu zovuta ntchito, monga mpweya, hydrogen peroxide, methane ndi ethylene. Thupi la valve la valve ya mpira likhoza kukhala lathunthu kapena lophatikizana.

Vavu ya mpira wa pneumatic ndi valavu ya pulagi ndi mtundu womwewo wa valavu. Malingana ngati gawo lake lotseka ndi mpira, mpirawo umazungulira kuzungulira pakati pa thupi la valve kuti ukwaniritse kutsegula ndi kutseka.

Valavu ya mpira wa pneumatic imagwiritsidwa ntchito kwambiri papaipi kuti itseke mwachangu, kugawa ndikusintha njira yoyendetsera sing'anga. Vavu ya mpira ndi mtundu watsopano wa valve, ili ndi ubwino wotsatira:

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. Ntchito yosindikiza ndi yabwino, ndipo zida zosindikizira za valve ya mpira zimagwiritsidwa ntchito kwambiri m'mapulasitiki, ndipo ntchito yosindikizira ndi yabwino, ndipo imagwiritsidwa ntchito kwambiri muzitsulo zowonongeka.

4. Zosavuta kugwiritsa ntchito, kutsegula mofulumira ndi kutseka, 90 ° kuzungulira kuchokera kutseguka kwathunthu mpaka kutsekedwa kwathunthu, koyenera kuwongolera kutali.

5. Kukonzekera ndikosavuta, valavu ya mpira wa pneumatic ili ndi dongosolo losavuta, ndipo mphete yosindikizira nthawi zambiri imasuntha, ndipo ndi yabwino kusokoneza ndikusintha.

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 ma diameter kuchokera ku mamilimita angapo mpaka mamita angapo, ndipo zingagwiritsidwe ntchito kuchokera ku vacuum yapamwamba mpaka kupanikizika kwambiri.

8. Popeza gwero lamphamvu la valve ya mpira ndi gasi, kupanikizika nthawi zambiri kumakhala 0.4-0.7MPa. Ngati valavu ya mpira wa Taike pneumatic ikutha, poyerekeza ndi hydraulic ndi magetsi, mpweya ukhoza kutulutsidwa mwachindunji.

9. Poyerekeza ndi ma valve a manual ndi turbo rolling mpira, ma valve a pneumatic mpira amatha kukhala ndi ma diameter akuluakulu. (Mavavu a mpira wamanja ndi turbo nthawi zambiri amakhala pansi pa DN300 caliber, ndipo mavavu a mpira wa pneumatic amatha kufikira ma calibers akulu.)
