Valve nkigikoresho cyavutse imyaka ibihumbi

Umuyoboronigikoresho gikoreshwa mugukwirakwiza no kugenzura gaze namazi byibuze imyaka igihumbi.

Kugeza ubu, muri sisitemu y'amazi ya fluid, kugenzura valve nicyo kintu cyo kugenzura, kandi umurimo wacyo nyamukuru ni ugutandukanya ibikoresho na sisitemu y'imiyoboro, kugenzura imigendekere, kwirinda gusubira inyuma, kugenzura no gusohora umuvuduko. Kubera ko ari ngombwa cyane guhitamo valve ikwiranye na sisitemu ya pipine, ni ngombwa kandi gusobanukirwa ibiranga valve n'intambwe n'ifatizo byo guhitamo valve.

Umuvuduko w'izina rya valve

Umuvuduko wizina wa valve werekana igishushanyo cyatanzwe nigitutu kijyanye nubukanishi bwibikoresho bigize imiyoboro, ni ukuvuga ko ari igitutu cyemewe cyakazi cya valve kubushyuhe bwagenwe, bujyanye nibikoresho bya valve. . Umuvuduko wakazi ntabwo ari umwe, kubwibyo, igitutu cyizina nikintu gishingiye kubintu bya valve kandi bifitanye isano nubushyuhe bwemewe bwakazi hamwe nigitutu cyakazi cyibikoresho.

Umuyoboro ni ikigo muri sisitemu yo kuzenguruka hagati cyangwa sisitemu yumuvuduko, ikoreshwa muguhindura umuvuduko cyangwa umuvuduko wikigereranyo. Ibindi bikorwa birimo kuzimya cyangwa gufungura itangazamakuru, kugenzura imigendekere, guhindura icyerekezo cyitangazamakuru, gukumira itangazamakuru gusubira inyuma, no kugenzura cyangwa guhumeka igitutu.

Iyi mikorere igerwaho muguhindura umwanya wo gufunga valve. Iri hinduka rirashobora gukorwa nintoki cyangwa mu buryo bwikora. Imikorere yintoki nayo ikubiyemo imikorere yo kugenzura intoki. Intoki zikoreshwa nintoki zitwa intoki. Umuyoboro urinda gusubira inyuma witwa cheque valve; imwe igenzura umuvuduko wubutabazi yitwa valve yumutekano cyangwa valve yubutabazi.

Kugeza ubu, inganda za valve zashoboye gutanga umusaruro wuzuye waamarembo, umubumbe wisi, ububiko bwa trottle, plaque ya plaque, imipira yumupira, indangagaciro zamashanyarazi, igenzura rya diaphragm, kugenzura indangagaciro, indangagaciro z'umutekano, umuvuduko ugabanya umuvuduko, imitego yumuriro hamwe na byihutirwa byugara. Valve ibicuruzwa byibyiciro 12, moderi zirenga 3000, nibisobanuro birenga 4000; igitutu kinini cyakazi ni 600MPa, diameter ntarengwa ni 5350mm, ubushyuhe bwo gukora ni 1200℃, ubushyuhe buke bwo gukora ni -196℃, kandi uburyo bukoreshwa ni Amazi, amavuta, amavuta, gaze karemano, itangazamakuru ryangirika (nka acide nitricike yibanze, acide sulfurike yo hagati, nibindi).

Witondere guhitamo valve:

1. Kugirango ugabanye ubutaka butwikiriye ubujyakuzimu,ikinyugunyugumuri rusange byatoranijwe kumuyoboro munini wa diameter; imbogamizi nyamukuru ya valve yikinyugunyugu nuko isahani yikinyugunyugu ifata igice runaka cyambukiranya amazi, cyongera gutakaza umutwe runaka;

2. Indangagaciro zisanzwe zirimoikinyugunyugu, amarembo, imipira yumupira hamwe nugucomeka, nibindi. Urutonde rwimyanda ikoreshwa murusobe rwamazi rugomba kwitabwaho muguhitamo.

3. Gutera no gutunganya imipira yumupira hamwe nugucomeka kumashanyarazi biragoye kandi bihenze, kandi mubisanzwe birakwiriye imiyoboro mito nini ya diametre. Umupira wumupira hamwe nugucomeka neza bikomeza ibyiza byurugi rumwe, irwanya amazi mato, kashe yizewe, ibikorwa byoroshye, gukora neza no kubungabunga. Amacomeka ya plaque nayo afite ibyiza bisa, ariko igice cyanyuze mumazi ntabwo ari uruziga rwiza.

4. Niba bidafite ingaruka nke kuburebure bwubutaka butwikiriye, gerageza uhitemo irembo; uburebure bw'irembo ry'amashanyarazi valve nini ya diametre ihagaritse irembo rya valve bigira ingaruka kubutaka butwikiriye ubutaka bwumuyoboro, kandi uburebure bwa diameter nini ya diameter nini ya horizontal bwongera ubuso butambitse bufashwe numuyoboro kandi bigira ingaruka kumitunganyirize yindi miyoboro;

5. Mu myaka yashize, kubera iterambere ry’ikoranabuhanga rya casting, ikoreshwa ry’umusenyi wa resin rishobora kwirinda cyangwa kugabanya gutunganya imashini, bityo bikagabanya ibiciro, bityo rero bishoboka ko imipira y’imipira ikoreshwa mu miyoboro minini ya diameter ikwiye gushakishwa. Kubijyanye n'umurongo utandukanya ubunini bwa kalibiri, bigomba gusuzumwa no kugabanywa ukurikije ibihe byihariye.
