Nibihe bintu biranga ububiko bwa kashe ya valve?

Ubuso bwa kashe ya valve ikunze kwangirika, kwangirika no kwambarwa nuburyo, bityo rero ni igice cyangiritse byoroshye kuri valve. Nka pneumatic ball valve na butterfly yamashanyarazi nibindi byuma byikora, kubera gufungura no gufunga byihuse kandi gufunga, ubuzima bwabo nibikorwa bya serivisi bigira ingaruka kuburyo butaziguye. Ibisabwa byibanze byububiko bwa kashe ni uko valve ishobora kwemeza neza kandi yizewe mugihe gikwiye. Kubwibyo, ibikoresho byo hejuru bigomba kugira ibintu bikurikira:

(5) Kurwanya isuri, ubuso bwa kashe bugomba kuba bushobora kurwanya isuri yibitangazamakuru byihuta no kugongana kwingingo zikomeye;

Gukoresha imiterere n'amahame yo gutoranya ibikoresho bya valve bifunga ibikoresho byo hejuru. Ibikoresho byo hejuru bifunze bigabanijwemo ibyiciro bibiri: ibyuma nibyuma. Ibisabwa bikoreshwa mubikoresho bisanzwe bikoreshwa ni ibi bikurikira:

(1) Rubber. Ubusanzwe ikoreshwa muburyo bwo gufunga imiterere yumuvuduko muke woroshye-ufunze amarembo, ama diafragm valve, ikinyugunyugu, kugenzura indangagaciro nizindi.

(2) Plastike. Amashanyarazi akoreshwa mubuso bwa kashe ni nylon na PTFE, bifite ibimenyetso biranga ruswa nziza hamwe na coefficient ntoya.

(3) Babbitt. Bizwi kandi nko kwitwa alloy, ifite imbaraga zo kurwanya ruswa hamwe nubushobozi bwiza bwo kwiruka. Irakwiriye gufunga hejuru ya valve ifunga ammonia hamwe n'umuvuduko muke n'ubushyuhe bwa -70-150 ℃.

(4) Umuringa. Ifite imyambarire myiza yo kurwanya no kurwanya ubushyuhe runaka. Irakwiranye na valve yisi, guta ibyuma byinjira mumarembo no kugenzura valve, nibindi. Ikunze gukoreshwa mumazi hamwe na parike hamwe numuvuduko muke hamwe nubushyuhe butarenze 200 ℃.

(5) Chrome-nikel ibyuma bitagira umwanda. Ifite ruswa irwanya ruswa, irwanya isuri no kurwanya ubushyuhe. Birakwiriye kubitangazamakuru nka acide nitric aside.

(6) Chrome ibyuma bitagira umwanda. Ifite imbaraga zo kurwanya ruswa kandi ubusanzwe ikoreshwa mubibaya bifite umuvuduko mwinshi nubushyuhe butarenze 450 ℃ kumavuta, imyuka y'amazi nibindi bitangazamakuru.

(7) Icyuma kinini cya chromium igaragara. Ifite ruswa irwanya ruswa kandi ikora akazi gakomeye, kandi irakwiriye kumuvuduko mwinshi, amavuta yubushyuhe bwo hejuru, amavuta hamwe nibindi bitangazamakuru.

(8) Icyuma cya Nitrid. Ifite ruswa irwanya ruswa kandi irwanya gushushanya, kandi mubisanzwe ikoreshwa mumashanyarazi yumuriro wumuriro. Ibi bikoresho birashobora kandi gutoranywa kumurongo wumupira wumupira ufunze.

(9) Carbide. Ifite ibintu byiza byuzuye nko kurwanya ruswa, kurwanya isuri no kurwanya ibishushanyo, kandi bifite ubuzima burebure. Nibikoresho byiza byo gufunga. Bikunze gukoreshwa tungsten drill alloy hamwe na drill base alloy surfacing electrode, nibindi, birashobora gukora umuvuduko mwinshi cyane, hejuru yubushyuhe bwo hejuru cyane, bikwiranye namavuta, peteroli, gaze, hydrogen nibindi bitangazamakuru.

(10) Koresha amavuta yo gusudira. Hariho ibinyomoro bishingiye kuri cobalt, ibinyomoro bishingiye kuri nikel, hamwe na chine ishingiye ku binini, bifite imbaraga zo kurwanya ruswa kandi birwanya kwambara.

Kugirango hamenyekane umutekano n’ubwizerwe bwa kashe ya valve, ibikoresho byatoranijwe bigomba kugenwa ukurikije imiterere yihariye yakazi. Niba uburyo bubora cyane, muguhitamo ibikoresho, bigomba kuba byujuje imikorere yangirika mbere, hanyuma bikuzuza ibisabwa nibindi bintu; Ikidodo c'irembo ry'irembo kigomba kwitondera guhangana neza; Ibyingenzi byumutekano, ububiko bwa trottle hamwe na valve igenzura byangirika byoroshye nuburyo bworoshye, kandi hagomba gutoranywa ibikoresho bifite imbaraga zo kurwanya ruswa; Kuburyo bwubatswe bwimpeta yumubiri hamwe numubiri, ibikoresho bifite ubukana bwinshi bigomba gufatwa nkubuso bwa kashe; Imyanda rusange ifite ubushyuhe buke nigitutu igomba guhitamo reberi na plastike bifite imikorere myiza yo gufunga nkikimenyetso; Mugihe uhitamo ibikoresho bifunga kashe, twakagombye kumenya ko ubukana bwubuso bwintebe ya valve bugomba kuba burenze ubw'ubuso bwa kashe ya disiki.
