A ikinyugunyuguni ubwoko bwa valve ishobora gufungurwa cyangwa gufungwa uhindukirira inyuma nka dogere 90. Uwitekaikinyugunyuguikora neza mubijyanye no gutembera neza hiyongereyeho kugira ubushobozi bwiza bwo gufunga no gufunga, igishushanyo cyoroshye, ingano nto, uburemere bworoshye, gukoresha ibikoresho bike, kwishyiriraho byoroshye, moteri yo gutwara ibinyabiziga, no gukora byihuse. bumwe muburyo bwihuta bwa valve.Ibinyugunyugu bikoreshwa kenshi. Ubwoko nubugari bwimikoreshereze yabyo bigenda byiyongera, kandi biragenda bikoreshwa mubushyuhe bwo hejuru, umuvuduko mwinshi, diameter nini, gufunga hejuru, kuramba, kuranga bidasanzwe, hamwe nibikorwa byinshi. Ubu ifite urwego rwo hejuru rwo kwizerwa nibindi biranga imikorere.

Imikorere ya kinyugunyugu yarateye imbere bitewe no gukoresha reberi ya sintetike irwanya imiti. Kubera ko reberi yubukorikori ifite imiterere yo kurwanya ruswa, kurwanya isuri, ingano ihamye, kwihangana neza, koroshya imiterere, hamwe nigiciro gito, reberi yubukorikori ifite imitungo itandukanye irashobora guhitamo hakurikijwe ibisabwa bitandukanye kugirango ishobore guhaza imikorere yimibande yikinyugunyugu.

Kubera ko polytetrafluoroethylene (PTFE) ifite imbaraga zo kurwanya ruswa, imikorere ihamye, kurwanya gusaza, coefficient de fraisement, koroshya imiterere, hamwe nubunini bwubunini, imikorere yayo muri rusange irashobora kuzamurwa no kuzuza no kongeramo ibikoresho bikwiye kugirango bigere ku mbaraga nziza kandi guterana amagambo. Rubber ya sintetike ifite ibibi bimwe, ariko ibikoresho byo gufunga ikinyugunyugu bifunga coefficient yo hasi irabizenguruka. Mu rwego rwo kunoza imikorere ya kinyugunyugu, ibikoresho bya polymer bihanitse, nka polytetrafluoroethylene, hamwe nibikoresho byabo byahinduwe byakoreshejwe cyane. Ubu yarazamuwe, kandi ikinyugunyugu cyakozwe hamwe nubushyuhe bunini n’umuvuduko ukabije, imikorere yashyizweho ikimenyetso, hamwe nubuzima burebure.

Ibinyugunyugu bifunze bifunze byateye imbere cyane kugirango byuzuze ibisabwa ninganda nkubushyuhe bwo hejuru nubushyuhe buke, isuri ikomeye, nubuzima bwagutse. Ibibabi by'ikinyugunyugu bifunze cyane byakoreshejwe cyane mu nganda nk'ubushyuhe bwo hejuru n'ubushyuhe buke, isuri ikomeye, ndetse n'ubuzima burebure bitewe no gukoresha ubushyuhe bwo hejuru, ubushyuhe buke, kurwanya ruswa, kurwanya isuri, n'imbaraga nyinshi ibikoresho. Kugirango uteze imbere tekinoroji yikinyugunyugu, diameter nini (9-750mm), umuvuduko mwinshi (42.0MPa), hamwe nubushyuhe bwagutse (-196–606 ° C) ububiko bwikinyugunyugu bwa mbere.

Ikinyugunyugu gifite ikinyugunyugu gike iyo gifunguye neza. Imyanda y'ibinyugunyugu ikoreshwa kenshi murwego rwo kugenzura diameter nini kuko zishobora kugenzura neza imigezi ifunguye hagati ya 15 ° na 70 °.

Umubare munini wibinyugunyugu urashobora gukoreshwa hamwe nibitangazamakuru birimo uduce duto twahagaritswe kuva isahani yikinyugunyugu igenda ihanagura. Irashobora kandi gukoreshwa mubitangazamakuru bya granular na powdery, bitewe nimbaraga za kashe.

Ibinyugunyugu bifite akamaro ko kugenzura imigendekere. Iyo uhisemo ikinyugunyugu, ni ngombwa gusuzuma byimazeyo ingaruka zo gutakaza umuvuduko kuri sisitemu y'imiyoboro kimwe n'imbaraga z'isahani y'ibinyugunyugu kugira ngo uhangane n'umuvuduko w'ikigereranyo cy'umuyoboro iyo ufunze kuko gutakaza umuvuduko w'ikinyugunyugu. valve mu muyoboro ni nini cyane, hafi inshuro eshatu iy'irembo. Ubushyuhe bwo gukora bwibikoresho bya elastike ku bushyuhe bwo hejuru nabyo bigomba kwitabwaho.

Ikinyugunyugu gifite imiterere ngufi n'uburebure buke muri rusange. Ifungura kandi igafunga vuba kandi ifite ibintu byiza byo kugenzura amazi. Gukora ibipimo binini bya diameter nibyiza bikwiranye nigishushanyo mbonera cyibinyugunyugu. Intambwe yingenzi cyane muguhitamo ikinyugunyugu kizakora neza kandi neza mugihe gikoreshwa mugucunga imigendekere ni uguhitamo ubwoko bwiza nibisobanuro.

Ubusanzwe ibinyugunyugu birasabwa gukoreshwa mugukubita, kugenzura kugenzura, hamwe nibitangazamakuru byondo aho uburebure bugufi bwubatswe, gufungura byihuse no gufunga umuvuduko, hamwe no kugabanya umuvuduko muke (itandukaniro rito ryumuvuduko). Ibinyugunyugu birashobora gukoreshwa hamwe nibitangazamakuru byangiza, imiyoboro ya diametre yagabanutse, urusaku ruke, cavitation na vaporisation, akantu gato ko kumeneka kwikirere, no guhinduranya imyanya ibiri. Guhindura Throttle mugihe ukora mubihe bidasanzwe, nkigihe bifunze cyane, kwambara cyane, ubushyuhe buke cyane, nibindi nibindi.
