API Standard B367 Gr.C-2 Worm Gear Oprated Metal Seated Ball Valve

Mpira wa valavu ya mpira woyandama umayandama, ndipo pansi pa kukakamizidwa kwa sing'anga, mpirawo ukhoza kutulutsa malo enaake ndikukankhira mwamphamvu pamalo osindikizira kumapeto, kuonetsetsa kuti kusindikiza kutha. Valavu yoyandama ya mpira imakhala ndi mawonekedwe osavuta komanso osindikiza bwino, koma mpirawo umanyamula katundu wonse wa sing'anga yogwirira ntchito ndipo umaperekedwa ku mphete yosindikiza. Choncho, m'pofunika kuganizira ngati mphete yosindikiza ikhoza kupirira ntchito ya sing'anga ya mpira. Ukakumana ndi kuthamanga kwambiri, mpirawo ukhoza kupatuka. Kapangidwe kameneka kamakonda kugwiritsidwa ntchito ngati mavavu apakati komanso otsika.

Makhalidwe akuluakulu a valve ya mpira ndi mawonekedwe ake ophatikizika, kusindikiza kodalirika, kapangidwe kosavuta, kukonza kosavuta, ndi kusindikiza pamwamba ndi malo ozungulira nthawi zambiri amakhala otsekedwa, omwe sawonongeka mosavuta ndi sing'anga. Ndiosavuta kugwiritsa ntchito ndikusamalira, oyenera kugwiritsa ntchito wamba monga madzi, zosungunulira, ma acid, ndi gasi, komanso oyenera kugwira ntchito movutikira monga mpweya, hydrogen peroxide, methane, ndi ethylene. Zakhala zikugwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana. Thupi la valve la valavu ya mpira likhoza kukhala lofunikira kapena lofanana.

1. Kuthamanga kothamanga kwa valve ya mpira ndi kochepa. Pamene valavu ya mpira wam'mimba mwake imatsegulidwa, njira ya mpira, njira ya valavu, ndi kulumikiza chitoliro ndi m'mimba mwake zimakhala zofanana ndikupanga m'mimba mwake, ndipo sing'anga imatha kuyenda popanda kutaya kulikonse.

2. Valve ya mpira ikhoza kutsekedwa kwathunthu ndikutsegulidwa kwathunthu pozungulira 90 °, ndikutsegula mwachangu ndi kutseka. Poyerekeza ndi mavavu a pachipata ndi ma globe ofanana, ma valve a mpira amakhala ndi voliyumu yaying'ono komanso kulemera kopepuka, zomwe zimapangitsa kuti zikhale zosavuta kuziyika m'mapaipi.

3. Mpando wapamwamba kwambiri wa valve: Mpando wa valve umapangidwa malinga ndi zaka zambiri pakupanga valavu ya mpira, kuonetsetsa kuti kusindikiza kwa valve, kutsika kwapakati pa friction, torque yaing'ono yogwiritsira ntchito, zipangizo zogwiritsira ntchito ma valve angapo, ndi ntchito zambiri.

4. Chogwiritsira ntchito chopanda cholakwika chopanda cholakwika: pogwiritsa ntchito tsinde la valve lathyathyathya, kugwirizanitsa ndi chogwiriracho sikungasokonezedwe molakwika, kuonetsetsa kuti kusintha komwe kumasonyezedwa ndi chogwiriracho kumagwirizana ndi valavu.

5. Chipangizo chotsekera: Kuti muteteze kulephera kwa valve kutsegula ndi kutseka, pali mabowo otsekera m'malo otseguka ndi otsekedwa bwino a valve kuti atsimikizire kuti ali pamalo oyenera.

6. Mawonekedwe a valve anti-flying structure: Tsinde la valve limakhala pansi kuti liteteze kupanikizika kuti zisawuluke. Panthawi imodzimodziyo, imatha kupanga kukhudzana kwachitsulo ndi thupi la valve pambuyo pa moto, kuonetsetsa kuti tsinde la valve litsekedwa.
