Anti-corrosive fluorine ali ndi valavu ya mpira

1. Mpira wa dzenje lozungulira umagwiritsidwa ntchito ngati magawo otsegulira ndi kutseka, ndipo mpira wa tsinde la valve umazungulira kuzungulira pakati pa thupi la valve kuti uzindikire kutsegula ndi kutseka kwa valve.

2. Kapangidwe kakang'ono komanso koyenera, malo ocheperako a thupi la valve, kuchepetsa kusungidwa kwapakati. Pogwiritsa ntchito njira yapadera yopangira, kotero kuti kusindikiza pamwamba kumakhala bwino, kuphatikizapo V PTFE kulongedza kusakaniza, kuti valavu ikwaniritse zero kutayikira.

3. Mpira wa magawo otsegulira ndi kutseka ndi tsinde la valve amaponyedwa ngati chimodzi, kuti athetse kuthekera kwa tsinde la valve kuchokera ku ziwalo zoberekera zomwe zimayambitsidwa ndi kusintha kwamphamvu, ndikuonetsetsa kuti chitetezo cha ntchitoyo chikugwiritsidwa ntchito.

4.PFA/FEP lining, yokhala ndi kukhazikika kwamankhwala, imatha kugwiritsidwa ntchito pazinthu zina zilizonse zowononga zowononga kupatula "chitsulo chosungunuka cha alkali ndi element fluorine".

5. Tengani m'mimba mwake, mawonekedwe a mpira woyandama. Mavavu amachotsa kutayikira panthawi yonse yokakamiza kuti asesa bwino mpira komanso kukonza mizere.

Kapangidwe kaukadaulo ndi ma spindle box fluorine okhala ndi ma valve a mpira amawongolera mitundu yosiyanasiyana yazambiri zowononga, zomwe zimagwiritsidwa ntchito kwambiri mumafuta, mankhwala, mankhwala ophera tizilombo, utoto, asidi ndi mafakitale opanga zamchere, ndiye valavu yabwino kwambiri yoletsa kuwononga.
