Miyendo yosindikizidwa ya globe valvendi valavu yapadziko lonse lapansi yokhala ndi mvuto zotanuka zachitsulo komanso moyo wautali wotopa wa telescopic. Kugwiritsa ntchito mvuto chisindikizo kamangidwe, kuthetsa kwathunthu wamba tsinde kunyamula chisindikizo kukalamba mofulumira kutayikira zofooka, osati kusintha ntchito mphamvu dzuwa, kuwonjezera chitetezo cha zipangizo kupanga, kuchepetsa ndalama yokonza ndi kukonza pafupipafupi, komanso kupereka ukhondo ndi otetezeka malo ogwira ntchito.

Makhalidwe a mapangidwe a

1. Mapangidwe osindikizira awiri (mavuvu + kulongedza) Ngati mvuvu ikulephera, kulongedza tsinde kudzapewanso.

2. Kukonzekera koyenera, kusindikiza kodalirika, kuchita bwino kwambiri, maonekedwe okongola.

3. Palibe kutaya madzimadzi, kuchepetsa kutayika kwa mphamvu, kukonza chitetezo cha zida za zomera.

4. The sealing surface surfacing Co based hard alloy, kuvala kukana, kukana dzimbiri, kukana kukangana, moyo wautali wautumiki, kuchepetsa kuchuluka kwa kukonza, kuchepetsa ndalama zogwirira ntchito.

5. Mapangidwe olimba a ma bellows osindikizira amaonetsetsa kuti tsinde itsike ndipo palibe kukonza.

6. Kuyimitsa tsinde la valve ndi chithandizo cha nitriding pamwamba, chimakhala ndi kukana kwa dzimbiri komanso kukana kukangana;

7. Chizindikiro chowoneka bwino cha malo okweza tsinde la valve.

 Ntchito zosiyanasiyana

Valavu ya Bellows seal globe ndiyoyenera mafuta, mankhwala, mankhwala, feteleza wamankhwala, mphamvu yamagetsi ndi mafakitale ena pansi pamikhalidwe yosiyanasiyana yapaipi, yomwe imagwiritsidwa ntchito podula kapena kuyika mapaipi.
