Intangiriro:

Mu ikoreshwa rya buri munsi ry'abakoresha valve nini y'ibinyugunyugu, akenshi tugaragaza ikibazo, ni ukuvuga valve nini y'ibinyugunyugu ikoreshwa mu gutandukanya igitutu ni nini cyane, nk'umwuka w'umwuka, amazi afite umuvuduko mwinshi n'indi mirimo ikoreshwa mu gufunga, akenshi biragoye cyane kuyifunga, uko byagenda kose kuyifunga bigoranye, byanze bikunze hazabaho ikintu cyo kuva amazi, biragoye kuyifunga cyane, bigatuma habaho ikibazo giterwa n'imiterere y'icyuma kandi ubushobozi bw'umuntu bwo gusohora ntibuhagije.

Isesengura ry'impamvu zitera ingorane mu guhinduranya valve nini

Ingufu rusange z'umuntu mukuru zishobora gusohora mu buryo butambitse ni 60-90kg, bitewe n'ingano zitandukanye z'umubiri.

Icyerekezo rusange cy'inzira y'ikinyugunyugu cyagenewe kuba hasi no hejuru, iyo umuntu afunze ikinyugunyugu, umubiri w'umuntu ushyira urukiramende mu buryo butambitse kugira ngo ruzenguruke, ku buryo ikinyugunyugu cy'ikinyugunyugu kimanuka kugira ngo kigere ku gufunga, ibyo bikaba bikenewe kugira ngo utsinde imbaraga eshatu, arizo:

1) Igitutu cyo hejuru cya Axial Fa;

2) imbaraga zo gupakira no gukururana kw'imitsi Fb;

3) Uduce tw'ingenzi duhuza inkingi n'igice cy'ingenzi cya valve Fc

Igiteranyo cy'umuvuduko ni ∑M=(Fa+Fb+Fc)R

Nkuko bigaragara, uko caliber iba nini, ni ko imbaraga zo gukurura umuyoboro ziba nyinshi, iyo zegereye imiterere yo gufunga, imbaraga zo gukurura umuyoboro ziba hafi y'umuvuduko nyakuri w'umuyoboro w'imiyoboro (kubera ifungwa rya P1-P2 ≈ P1, P2 = 0)

Iyo hakoreshejwe valve ya DN200 caliber butterfly ku muyoboro w'umwuka wa 10bar, gusa icyuma cya mbere cyo gufunga Fa = 10 × πr2 = 3140kg, kandi imbaraga zo kuzenguruka zikenewe kugira ngo zifungwe ziba zegereye umupaka w'imbaraga zo kuzenguruka zishobora gusohoka mu mubiri w'umuntu usanzwe, bityo biragoye cyane ko umuntu yafunga valve burundu muri ubwo buryo bw'akazi.

Birumvikana ko hari inganda zimwe zisaba gushyiraho ubwo bwoko bwa valve inyuma, ibyo bigakemura ikibazo cyo kugorwa no gufunga, ariko hanyuma hakavuka ikibazo cyo kugorwa no gufunga nyuma yo gufunga.

 

Uruganda rukora amashanyarazi rwa Tianjin Zhongfa Valve-ZFA rukora ishami ry'ikoranabuhanga, impamvu zo kuva kw'amashanyarazi rwa flange y'amashanyarazi rwa flange y'ibinyugunyugu zifite imiterere itandukanye bitewe na sisitemu zitandukanye, hari impamvu zitandukanye, izi zikurikira kugira ngo usesengure imanza ebyiri:

 

Ubwa mbere, igihe cyo kubaka giterwa n'ingufu nini z'amashanyarazi zituma valve y'ibinyugunyugu iva imbere mu buryo butunguranye: 

① gutwara no guterura nabi biterwa n'ibyangiritse muri rusange kuri valve nini y'amashanyarazi ya flange butterfly, bityo bigatuma valve nini y'amashanyarazi ya flange butterfly iva;

2. Uruganda, nyuma y’uko amazi atangiye kuzura, umuvuduko w’amazi wakozwe n’amashanyarazi, urufunguzo rw’ikinyugunyugu rudakora neza, kandi rugatuma habaho kwangirika kw’imbere mu gice cyo hejuru cy’urukuta;

③ Uburinzi bw'aho bubaka ntibuhari, imvange nini y'amashanyarazi y'ibinyugunyugu ntishyirwa ku mpera zombi z'imyanda idafite aho ihuriye n'amazi, imvura, umucanga n'indi myanda mu ntebe y'imvange, bigatuma amazi asohoka;

④ Mu gihe cyo gushyiraho, nta mavuta ashyirwa mu ntebe ya valve, bigatuma imyanda yinjira inyuma y'intebe ya valve, cyangwa ngo hatwikwe n'amazi asohoka imbere mu gihe cyo gusudira;

⑤ Valve ntabwo ishyirwa ahantu hose hafunguye, ibyo bikaba byangiza umupira. Mu gihe cyo gusudira, iyo valve idafunguye neza, icyuma gisuka umupira kizangiza umupira, kandi iyo umupira ufite icyuma gisuka umupira ufunguye kandi ukazimwa, bizongera kwangiza intebe ya valve, bityo bigatera kuvamo imyanda imbere;

⑥ Gusudira ibintu bisigaye n'ibindi bisigazwa by'ubwubatsi byatewe n'imivune yo gufunga ubuso;

Igihe cyo gushyiraho cyangwa igihe cyo kugishyiraho ntigikwiye bitewe n’aho kiva, niba agakoresho k’icyuma gitwara icyuma cyangwa ibindi bikoresho hamwe n’inguni yo guteranya icyuma, icyuma kinini cy’amashanyarazi cya flange kivamo amazi.

 

Icya kabiri, igihe cyo gukora giterwa n'impamvu zo kuva kw'imvange y'amashanyarazi y'ikinyugunyugu:

① Impamvu ikunze kugaragara ni uko umuyobozi w’ibikorwa azirikana ikiguzi gihenze cyo kubungabunga valve y’ibinyugunyugu by’amashanyarazi ifite umurambararo munini idakora isuku, cyangwa kutagira uburyo bwa siyansi bwo gucunga no kubungabunga valve y’ibinyugunyugu by’amashanyarazi ifite umurambararo munini idakora isuku yo kwirinda, bigatuma ibikoresho bipfa mbere y’igihe;

② imikorere idahwitse cyangwa idakurikije uburyo bwo kubungabunga buterwa no kuva kw'imbere mu nzu;

③ Mu mikorere isanzwe, ibisigazwa by'inyubako bikurura ubuso bufunga, bigatera amazi imbere;

④ Gusukura imiyoboro nabi byangiza ubuso bufunga bigatuma imbere hameneka;

⑤ Kudakora cyangwa kudakora neza kwa valve y'ibinyugunyugu ifite umurambararo munini, bigatuma intebe n'umupira bifatwa, bigatera kwangirika kw'ipfundikizo iyo uhinduye valve y'ibinyugunyugu ifite umurambararo munini kugira ngo ihinduke imbere;

⑥ Nta mashini yo gufunga icyuma cy'amashanyarazi ifite umurambararo munini ihari kugira ngo itume amazi yinjira imbere, icyuma cy'amashanyarazi gifite umurambararo munini iyo ari yo yose, uko umuntu afungura cyangwa agafunga, muri rusange uburebure bwa 2 ° ~ 3 ° bushobora gutuma amazi ava;

⑦ Ibyuma byinshi binini binini binini binini bikoreshwa mu gupima amashanyarazi ahanini bifite agace ko guhagarika inkingi, iyo bikoreshejwe igihe kirekire, bitewe n’ingese n’ubushyuhe n’izindi mpamvu hagati y’agace n’agace ko guhagarika inkingi bizakusanya ingese, umukungugu, irangi n’ibindi bisigazwa, ibi bisigazwa bizatuma ibyuma binini binini bidashobora kuzunguruka mu mwanya wabyo bigatuma biva - niba ibyuma binini binini bikoreshwa mu gupima amashanyarazi bishyinguwe, kongera uburebure bw’agace ko guhagarika amashanyarazi bizatera ingese nyinshi kandi imyanda ikabangamira uruziga rw’umupira w’ibyuma mu mwanya wabyo, bigatuma ibyuma binini biva mu gupima amashanyarazi.

⑧ Actuator rusange nayo ifite imipaka, niba impamvu y'igihe kirekire itera ingese, gukomera kw'amavuta cyangwa imipaka y'ibice biremereye birekuye bizatuma umupaka udakwiye, bigatuma imbere hasohoka amazi;

⑨ aho amashanyarazi atera imbere, ntaho bihuriye n'aho atera amazi imbere;

⑩ kutagira gahunda yo kubungabunga no kubungabunga buri gihe, bigatuma amavuta yumye kandi yumye afunga amavuta yumye kandi yumye afunga mu ntebe y'imashini irabagirana, bigatuma intebe y'imashini irangirika, bigatuma imashini inanirwa gukora neza.

Uruganda rwa ZFA Valve rufite amakipe y’abahanga mu by’ikoranabuhanga kugira ngo arebe ko buri vali y’imbere mu ruganda n’isura yayo ari nziza. Muri icyo gihe, dufite ikoranabuhanga ry’umwuga n’amatsinda akurikirana nyuma yo kugurisha kugira ngo afashe abakiriya gukemura ibibazo bitandukanye bahura nabyo mu gihe cyo kuyishyiraho no kuyikoresha.
