Itangira ry'ibikoresho bya valve y'umupira

Ibikoresho bya valve y'umupira biratandukanye kugira ngo bihuze n'imiterere itandukanye y'akazi n'ibisabwa mu buryo butandukanye. Ibi bikurikira ni bimwe mu bikoresho bya valve y'umupira isanzwe n'imiterere yayo:

1. Ibikoresho by'icyuma gikozwe mu cyuma

Icyuma cy'umukara: gikwiriye amazi, umwuka w'umwuka, umwuka, gazi, peteroli n'ibindi bikoresho bifite igitutu cya PN≤1.0MPa n'ubushyuhe -10℃ ~ 200℃. Ibirango bikunze gukoreshwa ni HT200, HT250, HT300, HT350.

Icyuma gishongeshwa: gikwiriye amazi, umwuka, umwuka n'amavuta hamwe n'umuvuduko wa PN≤2.5MPa n'ubushyuhe -30℃ ~ 300℃. Ibirango bikunze gukoreshwa ni KTH300-06, KTH330-08, KTH350-10.

Icupa rya Ductile: Rikwiriye PN≤4.0MPa, ubushyuhe -30℃ ~ 350℃ amazi, umwuka, umwuka n'amavuta n'ibindi bikoresho. Ibyiciro bikunze gukoreshwa ni QT400-15, QT450-10, QT500-7. Byongeye kandi, icyuma cya ductile cya silicone kidakira aside gikwiriye ibikoresho byangiza bifite igitutu cya nominel PN≤0.25MPa n'ubushyuhe buri munsi ya 120℃.

2. Icyuma kidasesagura

Valve y'icyuma kidashonga ikoreshwa cyane mu miyoboro y'umuvuduko uringaniye n'uw'ubushyuhe bwinshi, ifite ubushyuhe bwinshi, kandi ikoreshwa cyane mu nganda za shimi, peteroli, ishongesha n'izindi nganda. Ibikoresho by'icyuma kidashonga bifite ubushyuhe bwinshi kandi bikagira ubushyuhe bwinshi, bikwiranye n'ibintu bitandukanye byangiza n'ubushyuhe bwinshi.

3. Ibikoresho by'umuringa

Ifu y'umuringa: Ikwiriye amazi ya PN≤2.5MPa, amazi yo mu nyanja, ogisijeni, umwuka, amavuta n'ibindi bikoresho, ndetse n'ubushyuhe bwa -40℃ ~ 250℃. Ikoreshwa cyane ni ZGnSn10Zn2 (umuringa w'ibati), H62, Hpb59-1 (umuringa w'ibumba), QAZ19-2, QA19-4 (umuringa w'ibumba w'aluminiyumu) ​​n'ibindi.

Umuringa ushyushye cyane: ukwiriye gukoreshwa mu mwuka w'umwuka n'ibikomoka kuri peteroli bifite igitutu cya PN≤17.0MPa n'ubushyuhe bwa ≤570℃. Ibirango bikunze gukoreshwa ni ZGCr5Mo, 1Cr5Mo, ZG20CrMoV n'ibindi.

4. Ibikoresho by'icyuma cya karuboni

Icyuma cya karuboni gikwiriye amazi, umwuka w’umwuka, umwuka, hidrojeni, ammonia, azote n’ibikomoka kuri peteroli bifite igitutu cya PN≤32.0MPa n’ubushyuhe -30℃ ~ 425℃. Ibyiciro bikunze gukoreshwa ni WC1, WCB, ZG25 n’icyuma cyiza cyane 20, 25, 30 n’icyuma gito cyane 16Mn.

5. Ibikoresho bya pulasitiki

Valve y'umupira wa pulasitiki ikozwe muri pulasitiki ikoreshwa mu bikoresho fatizo, ikaba ikwiriye gukoreshwa mu gufata inzira yo gutwara hakoreshejwe ibikoresho byangiza. Plastike zikora neza nka PPS na PEEK zikunze gukoreshwa nk'intebe z'amarangi y'umupira kugira ngo sisitemu idatwarwa n'imiti ihari uko igihe kigenda gihita.

6. Ibikoresho bya ceramic

Valve y'umupira wa Ceramic ni ubwoko bushya bw'ibikoresho bya valve, ifite ubushobozi bwo kurwanya ingese no kwangirika. Ubunini bw'igishishwa cya valve burenze ibisabwa n'ibipimo ngenderwaho by'igihugu, kandi ibintu bya shimi n'imiterere ya mekanike by'ibikoresho by'ingenzi byujuje ibisabwa n'ibipimo ngenderwaho by'igihugu. Kuri ubu, ikoreshwa mu gukora ingufu zishyuha, ibyuma, peteroli, gukora impapuro, ubwubatsi bw'ibinyabuzima n'izindi nganda.

7. Ibikoresho byihariye

Icyuma gishyuha cyane: gikwiriye gukoreshwa mu gushyuha PN≤6.4MPa, ubushyuhe ≥-196℃ ethylene, propylene, gaze karemano y'amazi, azote y'amazi n'ibindi bikoresho. Ibirango bikunze gukoreshwa ni ZG1Cr18Ni9, 0Cr18Ni9, 1Cr18Ni9Ti, ZG0Cr18Ni9 n'ibindi.

Icyuma kidapfa gushonga: gikwiriye aside nitrike, aside asetiki n'ibindi bikoresho bifite igitutu cya nominel PN≤6.4MPa n'ubushyuhe ≤200℃. Ibirango bizwi ni ZG0Cr18Ni9Ti, ZG0Cr18Ni10 (ubudahangarwa bwa aside nitrike), ZG0Cr18Ni12Mo2Ti, ZG1Cr18Ni12Mo2Ti (ubudahangarwa bwa aside na urea) n'ibindi.

Muri make, guhitamo ibikoresho bya valve y'umupira bigomba kugenwa hakurikijwe imiterere yihariye y'akazi n'ibisabwa biciriritse kugira ngo imikorere isanzwe n'igihe kirekire ya valve ikomeze kuba myiza.
