Urutonde rw'ingenzi n'imiterere y'imikorere y'ibikoresho byo gufunga valve

Gufunga valve ni igice cy'ingenzi cya valve yose, intego yayo nyamukuru ni ukwirinda gusohoka,valveIntebe yo gufunga yitwa kandi impeta yo gufunga, ni ikigo gikorana neza n'icyuma kiri mu muyoboro kandi kikabuza icyo cyuma gutemba. Iyo valve iri gukoreshwa, hari ibyuma bitandukanye biri mu muyoboro, nk'amazi, gazi, peteroli, ibyuma bishonga, nibindi, kandi ibyuma bifunga by'ibyuma bitandukanye bikoreshwa ahantu hatandukanye kandi bishobora guhinduka mu bikoresho bitandukanye.

TWSValveIbi bikwibutsa ko ibikoresho by'imitako ya valve bishobora kugabanywamo ibyiciro bibiri, ari byo ibikoresho by'icyuma n'ibitari ibyuma. Imitako itari ibyuma ikoreshwa muri rusange mu miyoboro ku bushyuhe busanzwe n'umuvuduko usanzwe, mu gihe imitako y'icyuma ifite uburyo bwinshi bwo kuyikoresha kandi ishobora gukoreshwa ku bushyuhe bwinshi.

1. Rubber y'ubukorikori

Rubber y'ubukorikori ni nziza kurusha rubber karemano mu bijyanye no kurwanya amavuta, kurwanya ubushyuhe no kurwanya ingese. Muri rusange, ubushyuhe bw'imikorere ya rubber y'ubukorikori ni t≤150°C, umugozi karemano ni t≤60°C, na rubber ikoreshwa mu gufunga valves z'isi, valves z'irembo, valves za diaphragm, valves z'ibinyugunyugu, valves zo kugenzura, valves zo gukanda n'izindi valves zifite umuvuduko wa nominel PN.≤1MPa.

2. Nayiloni

Nayiloni ifite imiterere y'ubushyuhe buke kandi irwanya ingese neza. Nayiloni ikoreshwa cyane cyane ku mavali y'umupira n'amavali y'isi yose afite ubushyuhe bwa t≤90°C n'umuvuduko wa nominel PN≤32MPa.

3. Polytetrafluoroethylene

PTFE ikoreshwa cyane cyane ku mavali yo ku isi, amavali yo ku irembo, amavali y'umupira, n'ibindi bifite ubushyuhe bwa t≤232°C na PN y'igitutu cy'izina≤6.4MPa.

4. Icyuma gishongeshejwe

Icyuma gikoreshwa mu gufunga amadirishya, amadirishya yo mu bwoko bwa 'globe valves', amadirishya yo kuziba, n'ibindi.≤100°C, igitutu cy'amazina PN≤1.6MPa, gazi na peteroli.

5. Ingano ya Babbitt

Aloyi ya Babbitt ikoreshwa kuri vali y'umubumbe wa ammonia ifite ubushyuhe bwa t-70 ~ 150℃n'umuvuduko wa PN≤2.5MPa.

6. Ifu y'umuringa

Ibikoresho bikunze gukoreshwa mu gukora aloyi z'umuringa ni bronze ya 6-6-3 tin na manganese 58-2-2 brass. Aloyi y'umuringa ifite ubushobozi bwo kwangirika neza kandi ikwiriye amazi n'umwuka w'umwuka hamwe n'ubushyuhe bwa t≤200℃n'umuvuduko wa PN≤1.6MPa. Ikunze gukoreshwa mu mavali y'irembo, amavali y'isi yose, amavali yo kugenzura, amavali yo kuziba, n'ibindi.

7. Icyuma kitagira umugese cya Chrome

Ibyuma bita chromium stainless steel bikunze gukoreshwa ni 2Cr13 na 3Cr13, byazimye kandi bikonjeshwa, kandi bifite ubushobozi bwo kurwanya ingese neza. Akenshi bikoreshwa ku byuma by'amazi, umwuka n'amavuta bifite ubushyuhe bwa t≤450℃n'umuvuduko wa PN≤32MPa.

8. Icyuma kitagira umugese cya Chrome-nickel-titanium

Ikoreshwa cyane mu byuma bita chromium-nickel-titanium stainless steel ni 1Cr18Ni9ti, ifite ubushobozi bwo kurwanya ingese, kurwanya isuri no kurwanya ubushyuhe. Ikwiriye gukoreshwa mu mwuka w'umwuka n'ibindi bikoresho bifite ubushyuhe bwa t≤600°C na PN y'igitutu cy'izina≤6.4MPa, kandi ikoreshwa kuri vali zo ku isi, vali z'umupira, n'ibindi.

9. Icyuma gitera nitridi

Icyuma gikoreshwa cyane mu gusya nitride ni 38CrMoAlA, gifite ubushobozi bwo kurwanya ingese no gushwanyagurika nyuma yo gusukura kaburimbo. Akenshi gikoreshwa mu mavali y'irembo ry'imashini z'amashanyarazi afite ubushyuhe bwa t≤540℃n'umuvuduko wa PN≤10MPa.

10. Guhindura ibara ry'umuhondo (Boronizing)

Boronizing itunganya neza ubuso bwo gufunga uhereye ku bikoresho by'umubiri wa valve cyangwa disiki, hanyuma igatunganya ubuso bwa boronizing. Ubuso bwo gufunga bufite ubushobozi bwo kwangirika neza. Ku bijyanye na valve yo gusohora amashanyarazi.

Iyo valve ikoreshwa, ibintu bigomba kwitabwaho ni ibi bikurikira:

1. Imikorere yo gufunga ya valve igomba gupimwa kugira ngo harebwe imikorere yayo.

2. Reba niba ubuso bwo gufunga bwa valve bwashaje, hanyuma ubisane cyangwa ubisimbuze bitewe n'uko ibintu bimeze.
