Intangiriro y'ibikoresho byo gufunga valve—TWS Valve

Ibikoresho byo gufunga valve ni igice cy'ingenzi mu gufunga valve. Ni ibihe bikoresho byo gufunga valve? Tuzi ko ibikoresho byo gufunga valve bigabanyijemo ibyiciro bibiri: icyuma n'ibitari icyuma. Ibi bikurikira ni intangiriro ngufi ku mikoreshereze y'ibikoresho bitandukanye byo gufunga, ndetse n'ubwoko bwa valve bukunze gukoreshwa.

1. Rubber y'ubukorikori

Imiterere rusange ya rubber ikoze mu buryo bwa sintetike nko kurwanya amavuta, kurwanya ubushyuhe no kurwanya ingese ni byiza kuruta iya rubber isanzwe. Muri rusange, ubushyuhe bw'ikoreshwa rya rubber ikoze mu buryo bwa sintetike ni t≤150℃, naho ubushyuhe bwa rubber ikoze mu buryo bwa sintetike ni t≤60℃. Rubber ikoreshwa mu gufunga valve z'isi,valve yo kwinjira yicayeho karaba, uturindantoki tw'inyuma,rvalve y'ikinyugunyugu cyicayeho ubber, rvalve yo kugenzura swing yicaye ku giti cy'umuntu (valve zo kugenzura), valve zo gukanda n'izindi valve zifite umuvuduko wa nominel PN≤1MPa.

2. Nayiloni

Nayiloni ifite imiterere y’uburyo bwo gukururana buto kandi irwanya ingese neza. Nayiloni ikoreshwa cyane cyane ku mavali y’umupira n’amavali y’isi yose afite ubushyuhe bwa t≤90℃ n’umuvuduko wa nominel PN≤32MPa.

3. PTFE

PTFE ikoreshwa cyane cyane ku mavali yo ku isi,valve zo mu irembo, valve z'umupira, n'ibindi bifite ubushyuhe t≤232℃ n'umuvuduko wa nominel PN≤6.4MPa.

4. Icyuma gishongeshejwe

Icyuma gikoreshwa mu gucukuravalve y'irembo, valve y'isi, valve yo gushyiramo icyuma, nibindi. ku bushyuhe t≤100℃, igitutu cya nominel 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 nominel PN ≤ 2.5MPa.

6. Ifu y'umuringa

Ibikoresho bisanzwe bikoreshwa mu gukora umuringa ni umuringa wa 6-6-3 hamwe n'umuringa wa manganese wa 58-2-2. Uwo muringa ufite ubushobozi bwo kwangirika neza kandi ukwiriye amazi n'umwuka ufite ubushyuhe bwa t≤200℃ n'umuvuduko wa PN≤1.6MPa. Akenshi ukoreshwa muvalve zo mu irembo, valves z'isi,valve zo kugenzura, valve zo gushyiramo plug, n'ibindi.

7. Icyuma kitagira umugese cya Chrome

Ingano zikunze gukoreshwa za chromium stainless steel ni 2Cr13 na 3Cr13, zamaze kuzimwa no gushyuha, kandi zifite ubushobozi bwo kurwanya ingese. Ikunze gukoreshwa mu byuma bikoreshwa mu byuma nk'amazi, umwuka n'amavuta bifite ubushyuhe bwa t≤450℃ n'umuvuduko wa PN≤32MPa.

8. Icyuma kitagira umugese cya Chromium-nickel-titanium

Ikoreshwa cyane mu byuma bitagira umugese bya chromium-nickel-titanium ni 1Cr18Ni9ti, bifite ubushobozi bwo kurwanya ingese, kurwanya isuri no kurwanya ubushyuhe. Bikwiriye umwuka, aside nitrike n'ibindi bikoresho bifite ubushyuhe bwa t≤600℃ n'umuvuduko wa nominel PN≤6.4MPa, bikoreshwa mu gukora valve y'isi, valve y'umupira, nibindi.

9. Icyuma gikozwe muri nitride

Ibyuma bikunze gukoreshwa cyane ni 38CrMoAlA, bifite ubushobozi bwo kurwanya ingese no gushwanyagurika nyuma yo kuvurwa na carburizing. Bikunze gukoreshwa muri valve y'irembo ry'imashini y'amashanyarazi ifite ubushyuhe bwa t≤540℃ n'umuvuduko wa nominel 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. Ikoreshwa muri valve yo gusohora amashanyarazi.
