Ibyiciro byingenzi nibikorwa bya serivise zifunga ibikoresho

Gufunga Valve nigice cyingenzi cya valve yose, intego nyamukuru ni ukurinda kumeneka,indangantegoicyicaro cyo gufunga nanone cyitwa impeta ya kashe, ni ishyirahamwe rihura neza nuburyo bwo mu muyoboro kandi bikabuza uburyo bwo gutemba. Iyo valve ikoreshwa, hari itangazamakuru ritandukanye mumuyoboro, nk'amazi, gaze, amavuta, itangazamakuru ryangirika, nibindi, kandi kashe ya valve itandukanye ikoreshwa ahantu hatandukanye kandi irashobora guhuza nuburyo butandukanye.

TWSValveikwibutsa ko ibikoresho bya kashe ya valve bishobora kugabanywamo ibyiciro bibiri, aribyo bikoresho byuma nibikoresho bitari ibyuma. Ikidodo kitari icyuma gikoreshwa mubisanzwe mu bushyuhe n'ubushyuhe busanzwe, mugihe kashe yicyuma ifite uburyo bwagutse bwo gukoreshwa kandi irashobora gukoreshwa mubushyuhe bwinshi. umuvuduko mwinshi.

1. Rubber

Rubber ya sintetike iruta reberi karemano mubijyanye no kurwanya amavuta, kurwanya ubushyuhe no kurwanya ruswa. Mubisanzwe, ubushyuhe bwimikorere ya reberi yubukorikori ni t≤150°C, reberi karemano ni t≤60°C.≤1MPa.

2. Nylon

Nylon ifite ibimenyetso biranga coefficient ntoya kandi irwanya ruswa. Nylon ikoreshwa cyane kumipira yumupira hamwe nisi yisi hamwe nubushyuhe t≤90°C n'umuvuduko w'izina PN≤32MPa.

3. Polytetrafluoroethylene

PTFE ikoreshwa cyane mubibumbe byisi, imipira yumuryango, imipira yumupira, nibindi hamwe nubushyuhe t≤232°C hamwe nigitutu cyizina PN≤6.4MPa.

4. Shira icyuma

Ibyuma bikoreshwa bikoreshwa mumarembo, isi yose, gucomeka, nibindi kubushyuhe t≤100°C, igitutu cyizina PN≤1.6MPa, gaze na peteroli.

5. Babbitt alloy

Babbitt alloy ikoreshwa kuri ammonia globe valve hamwe nubushyuhe t-70 ~ 150℃n'umuvuduko w'izina PN≤2.5MPa.

6. Umuringa

Ibikoresho bikunze gukoreshwa kumuringa wumuringa ni 6-6-3 amabati yumuringa na 58-2-2 umuringa wa manganese. Umuringa wumuringa ufite imbaraga zo kwambara kandi ukwiranye namazi hamwe nubushyuhe t≤200℃n'umuvuduko w'izina PN≤1.6MPa. Bikunze gukoreshwa mumarembo, mumibumbe yisi, kugenzura ububiko, gucomeka, nibindi.

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 kumibande yamazi, amavuta na peteroli hamwe nubushyuhe t≤450℃n'umuvuduko w'izina PN≤32MPa.

8. Chrome-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. Birakwiriye guhumeka nibindi bitangazamakuru bifite ubushyuhe t≤600°C hamwe nigitutu cyizina PN≤6.4MPa, kandi ikoreshwa mububiko bwisi, imipira yumupira, nibindi.

9. Icyuma cya Nitriding

Icyiciro gikunze gukoreshwa nicyuma cya nitriding ni 38CrMoAlA, ifite imbaraga zo kurwanya ruswa no kurwanya scratch nyuma yo kuvura karburize. Bikunze gukoreshwa mumashanyarazi ya sitasiyo yumuriro hamwe nubushyuhe t≤540℃n'umuvuduko w'izina PN≤10MPa.

10. Boronizing

Boronizing itunganya neza ikidodo kiva mubikoresho byumubiri wa valve cyangwa umubiri wa disiki, hanyuma ikora ubuvuzi bwa boronizing. Ubuso bwa kashe bufite imbaraga zo kwihanganira kwambara. Kumashanyarazi yamashanyarazi.

Iyo valve ikoreshwa, ibibazo bigomba kwitabwaho nibi bikurikira:

1. Kashe ya kashe ya valve igomba kugeragezwa kugirango irebe imikorere yayo.

2. Reba niba hejuru yikimenyetso cya valve yambarwa, hanyuma usane cyangwa uyisimbuze ukurikije uko ibintu bimeze.
