Ibikoresho byo gufunga ibikoresho ni igice cyingenzi cyo gufunga valve. Nibihe bikoresho byo gufunga valve? Turabizi ko ibikoresho bya valve bifunga impeta bigabanyijemo ibyiciro bibiri: ibyuma nibyuma. Ibikurikira nintangiriro ngufi yo gukoresha ibintu bitandukanye bifunga kashe, kimwe nubwoko bukoreshwa na valve.
Rubber
Imiterere yuzuye ya reberi yubukorikori nko kurwanya amavuta, kurwanya ubushyuhe no kurwanya ruswa biruta ibya reberi karemano. Mubisanzwe, ikoreshwa ryubushyuhe bwa reberi yubukorikori ni t≤150 and, nubushyuhe bwa reberi karemano ni t≤60 ℃ .Icyuma gikoreshwa mugushiraho ibimenyetso byisi,rubber yicaye kumarembo, diafragm valve,rubber yicaye ikinyugunyugu, rubber yicaye swing kugenzura valve (reba indanga), pinch valve nibindi byuma bifite igitutu nominal PN≤1MPa.
2. Nylon
Nylon ifite ibimenyetso biranga coefficient ntoya kandi irwanya ruswa. Nylon ikoreshwa cyane mumipira yumupira hamwe nububiko bwisi hamwe nubushyuhe t≤90 ℃ hamwe numuvuduko wizina PN≤32MPa.
3. PTFE
PTFE ikoreshwa cyane mububiko bwisi,amarembo, imipira yumupira, nibindi hamwe nubushyuhe t≤232 ℃ numuvuduko wizina PN≤6.4MPa.
4. Shira icyuma
Gukoresha ibyuma bikoreshwairembo, umubumbe wisi, gucomeka, nibindi byubushyuhe t≤100 ℃, umuvuduko wizina PN≤1.6MPa, gaze namavuta.
5. Babbitt alloy
Babbitt alloy ikoreshwa kuri ammonia globe valve hamwe nubushyuhe t-70 ~ 150 ℃ hamwe numuvuduko wizina PN≤2.5MPa.
6. Umuringa
Ibikoresho bisanzwe kumuringa wumuringa ni 6-6-3 amabati yumuringa na 58-2-2 umuringa wa manganese. Umuringa wumuringa ufite imbaraga zo kwihanganira kwambara kandi ubereye amazi namazi hamwe nubushyuhe t≤200 ℃ hamwe numuvuduko wizina PN≤1.6MPa. Bikunze gukoreshwa muriamarembo, umubumbe w'isi,reba indanga, Gucomeka,
7. Chrome ibyuma bitagira umwanda
Ibyiciro bikunze gukoreshwa mubyuma bya chromium bidafite ibyuma ni 2Cr13 na 3Cr13, byazimye kandi birashyuha, kandi bifite imbaraga zo kurwanya ruswa. Bikunze gukoreshwa mubibaya kubitangazamakuru nk'amazi, amavuta na peteroli hamwe n'ubushyuhe t≤450 ℃ hamwe n'umuvuduko w'izina PN≤32MPa.
8. Chromium-nikel-titanium ibyuma bitagira umwanda
Icyiciro gikunze gukoreshwa cya chromium-nikel-titanium ibyuma bitagira umuyonga ni 1Cr18Ni9ti, ifite imbaraga zo kurwanya ruswa, kurwanya isuri no kurwanya ubushyuhe. Irakwiranye na parike, aside nitricike nibindi bitangazamakuru bifite ubushyuhe t≤600 ℃ hamwe nigitutu cyizina PN≤6.4MPa, ikoreshwa kuri globe yisi, umupira wumupira, nibindi.
9. Icyuma cya Nitrid
Urwego rusanzwe rukoreshwa mubyuma bya nitride ni 38CrMoAlA, ifite imbaraga zo kurwanya ruswa no kurwanya ibishushanyo nyuma yo kuvura karburize. Bikunze gukoreshwa mumashanyarazi ya sitasiyo ya valve hamwe nubushyuhe t≤540 ℃ hamwe numuvuduko wizina PN≤10MPa.
10. Boronizing
Boronizing itunganya neza kashe hejuru yumubiri wa valve cyangwa umubiri wa disiki, hanyuma igakora ubuvuzi bwa boronizing, hejuru yikidodo gifite kwihanganira kwambara. Byakoreshejwe mumashanyarazi yamashanyarazi.
