1. Kuchuluka
Magawo a DN amaphatikizapo DN15mm ~ 600mm (1/2 ”~ 24”) ndi ma PN kuyambira PN1.6MPa ~ 20MPa (ANSI CLASS150 ~ 1500) yamphamvu, yolumikizidwa, BW ndi SW swing ndikukweza valavu.
2.Usage:
2.1 Valavu iyi ndiyoteteza kuyenda kwapakati m'mbuyo mu dongosolo la chitoliro.
2.2 Zinthu zamagetsi zimasankhidwa malinga ndi sing'anga.
2.2.1WCB valavu ndioyenera madzi, nthunzi ndi sing'anga mafuta etc.
2.2.2SS valavu ndi yoyenera pazenera.
2.3 Kutentha:
2.3.1Common WCB ndiyabwino kutentha -29 ℃ ~ + 425 ℃
2.3.2Alloy valve ndiyabwino kutentha≤550 ℃
Valavu ya 2.3.3SS ndiyabwino kutentha-196 ℃ ~ + 200 ℃
3. Kapangidwe ndi magwiridwe antchito
3.1 Kapangidwe kake kali pansipa:
3.2 PTFE ndi graphite yosinthika imavomerezedwa ku gasket yowonongeka kuti iwonetsetse kusindikiza.
(A) Kuwotcherera kumalumikiza kuthamanga kwambiri kudzisindikiza ndikutsegula valavu
(B) Kuwotcherera kwapadera kumakweza valavu yowunika
(C) BW Kukweza Check Valve (D) Flanged Check Valve
- Thupi 2. Disc 3. Shaft 4. Gasket 5. Bonnet
(E) BW Swing Check Valve
(F) Kuyang'ana Kwambiri

6. Kusunga & Kukonza & Kuyika & Ntchito
6.1 vavu ziyenera kusungidwa mu chipinda youma ndi mpweya wokwanira. Malekezero a ndimeyi ayenera plugged ndi chimakwirira.
Ma 6.2 mavavu omwe amasungidwa nthawi yayitali amayenera kuyesedwa ndikuyeretsedwa pafupipafupi, makamaka kukhala pansi kuti asawonongeke, ndipo nkhope yanu ikhale yokutidwa ndi dzimbiri loletsa mafuta
Kuyika cholozera cha 6.3 kuyenera kufufuzidwa kuti mugwiritse ntchito.
6.4 Valve patsekeke ndi kusindikiza pamwamba ayenera kufufuzidwa pamaso unsembe ndi kuchotsa dothi ngati pali.
6.5Arrow malangizo ayenera kukhala ofanana ndi njira yolowera.
6.6 Kukweza ofukula chimbale vavu cheke ayenera kuikidwa vertically kwa payipi ndi. Kukweza valavu yopingasa yoyeserera kuyenera kukhazikitsidwa mopingasa ku payipi.
6.7 Kugwedera kuyenera kuyang'aniridwa ndikusintha kwapayipi kwapakati pamagetsi kuti zisawonongeke kwa madzi.

8. Chitsimikizo
Valve itayamba kugwiritsidwa ntchito, nthawi ya valavu ndi miyezi 12, koma siyidutsa miyezi 18 kuchokera tsiku lobereka. Pakati pa nthawi ya chitsimikizo, wopanga amapereka ntchito yokonza kapena zida zina zaulere kwaulere pazowonongeka chifukwa chakuthupi, kapangidwe kake kapena kuwonongeka ngati ntchitoyi ndi yolondola.
