Kugwiritsiridwa ntchito ndi mawonekedwe a valve yowunikira

一, Kugwiritsa ntchito:

Valavu yowunika ya didlink imayikidwa mu dongosolo la mapaipi, ndipo ntchito yake yayikulu ndikuletsa sing'angayo kuti isabwerere. Valve yowunikira ndi valavu yodziwikiratu yomwe imadalira kuthamanga kwapakati kuti mutsegule ndi kutseka. Wafer cheke valavu ndi oyenera mapaipi osiyanasiyana ndi kuthamanga mwadzina PN1.0MPa ~ 42.0MPa, Class150 ~ 25000, awiri mwadzina DN15 ~ 1200mm, NPS1/2 ~ 48, ntchito kutentha -196 ~ 540 ℃, kuteteza sing'anga umayenda mmbuyo. Posankha zinthu zosiyanasiyana, zitha kugwiritsidwa ntchito pazinthu zosiyanasiyana monga madzi, nthunzi, mafuta, nitric acid, acetic acid, media oxidizing media, ndi uric acid.

二、Mapangidwe:

1. Kutalika kwake ndi kochepa, ndipo kutalika kwake ndi 1/4 ~ 1/8 chabe ya valve yowunikira flange;

2. Kukula kwakung'ono ndi kulemera kwake, kulemera kwake ndi 1/4 ~ 1/20 yokha ya valve yowunikira flange;

3. Chovala cha valve chimatseka mwamsanga ndipo kuthamanga kwa nyundo yamadzi kumakhala kochepa;

4. Mapaipi onse opingasa ndi mipope yowongoka angagwiritsidwe ntchito, ndipo kukhazikitsa ndikosavuta;

5. Njira yothamanga imakhala yosasunthika ndipo kukana kwamadzimadzi kumakhala kochepa;

6. Kuchita mwachidwi ndi ntchito yabwino yosindikiza;

7. Disiki ya valve ili ndi sitiroko yaifupi ndi kutseka kochepa;

8. Mapangidwe onse ndi ophweka komanso osakanikirana, ndipo maonekedwe ndi okongola.

9. Moyo wautali wautumiki ndi ntchito yodalirika.
