I. Flanged Nkitahodi ahorow

Amansan nkitahodi kwan no nya nsɔano denam bolted fastening of paired flanges.

Nsɔano ahorow a wɔtaa yɛ:

-Protruding surface: Nsusuwii a wɔtaa yɛ, a sealing surface protruding 2-3mm, a ɛfata ma nhyɛso a ɛtrɛw (PN10-PN25).

-Concave-convex soro: sealing adwumayɛ a eye, ɛfata ma ogya ne awuduru media.

-Groove soro: sealing a eye sen biara, wɔde di dwuma ma nsɛm ho amanneɛbɔ a ɛyɛ hu kɛse ne nhyɛso a ɛkorɔn tebea horow.

-Ring connection surface: Metal ring gasket, a wɔayɛ ama nhyɛsoɔ a ɛkorɔn ne ɔhyew a ɛkorɔn dwumadie. Mfaso: Nsɔano a wotumi de ho to so na ɛnyɛ den sɛ wobɛpaapae mu.

-Type: Butt welding: Ahoɔden a ɛkorɔn, nsu a ɛba fam a ɛko tia, ɛfata ma adwumayɛ tebea a emu yɛ den.

-Plug-in welding nkitahodi: Ɛnyɛ den sɛ wode besisi, ɛfata ma nketewa-diameter paipu. Mfaso a ɛwɔ so: Zero leakage, vibration-resistant.

Drawbacks: 5. Ɛyɛ den sɛ wobɛpaapae nneɛma mu. Nkitahodi ahorow afoforo: Nkitahodi a wɔde kyekyere nneɛma: Wɔde di dwuma wɔ ahotew adwumayɛbea ahorow mu ma ɛyɛ mmerɛw sɛ wɔbɛhohoro ho. Sleeve nkitahodi: Wɔde di dwuma wɔ nnwinnade ne nsu nhyehyɛe mu.

Nsɛntitiriw a wɔpaw:

1. Paw ɔkwan no sɛnea nhyɛso ne ɔhyew te: nhyɛso a ɛkorɔn ne ɔhyew a ɛkorɔn ɛsɛ sɛ wɔde weld anaa ring nkitahodi.

2. Egyina medium su so: Wɔ media a asiane wom ho no, wɔkamfo welding anaa tenon-joint surfaces kyerɛ.

3. Susuw nhyehyɛe ne nsiesie ho: Mpɛn pii disassembly of flange nkitahodi.

4. Ɛka ne Atenae: Wafer no yɛ nea ɛho ka sua na ɛyɛ ketewaa.
