Jacketed Insulation Ball Valve: Mayankho Ogwiritsa Ntchito Mphamvu Zamadzimadzi

Valavu ya mpira wokhala ndi jekete ndi mtundu wa valavu wokhala ndi zotsekemera zabwino komanso zoziziritsa. awiri ake n'zogwirizana ndi m'mimba mwake chitoliro, amene angathe kuchepetsa kutentha imfa ya sing'anga mu payipi. Valavu yamtunduwu imagwiritsidwa ntchito makamaka m'machitidwe osiyanasiyana monga mafuta, mankhwala, zitsulo, kupanga, ndi chakudya, ndipo amagwiritsidwa ntchito kunyamula mauthenga apamwamba a viscosity omwe amalimbitsa kutentha.

Makhalidwe a mavavu opangidwa ndi jekete a mpira amaphatikizanso mfundo izi:

1. Kukaniza kwamadzimadzi kumakhala kochepa, ndipo kukana kwake kumakhala kofanana ndi mapaipi a kutalika kwake;

2. Kapangidwe kosavuta, kakulidwe kakang'ono, ndi kulemera kopepuka;

3. Yolimba komanso yodalirika, yokhala ndi ntchito yabwino yosindikiza, pulasitiki imagwiritsidwa ntchito kwambiri ngati chinthu chosindikizira pamwamba ndipo imagwiritsidwanso ntchito kwambiri m'makina a vacuum;

4. Yosavuta kugwiritsa ntchito, yofulumira kutsegula ndi kutseka, ndi kuzungulira kwa 90 ° kuchokera kutseguka kwathunthu mpaka kutseka kwathunthu, kumathandizira kulamulira kwakutali;

5. Kukonza kosavuta, mawonekedwe osavuta a valve, komanso mphete zosindikizira zomwe zimasunthika, zomwe zimapangitsa kuti disassembly ndi m'malo zikhale zosavuta;

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

Mapangidwe ake, kutalika kwake, kuyezetsa kutentha kwa kutentha kwa flange ndi kuyang'anira ma valve otsekedwa ndi jekete amatsata mfundo monga GB/T9113, JB/T79, JB/T9092, GB/T12221, GB/T12224, GB/T12237, GB/T13927 , AP1598, HG/T20592, EN1092, ndi zina zotero.

Zida zazikulu za jekete zotetezedwa ndi mavavu a mpira zikuphatikizapo jekete (PTFE), mpando wa valve (WCB), thupi la valve (WCB), mphete yosindikizira (PTFE, alignment polystyrene), mpira (chitsulo chosapanga dzimbiri), tsinde la valve (1Cr13), kunyamula ( graphite flexible), ndi packing gland (WCB).

Ponseponse, ma valve opangidwa ndi jekete a mpira ndi mtundu wa valavu yokhala ndi magwiridwe antchito apamwamba, osavuta kugwiritsa ntchito, komanso kukonza kosavuta. Amagwiritsidwa ntchito kwambiri pamakina osiyanasiyana ndipo ndi njira yabwino yoperekera makanema apamwamba kwambiri.
