A valve y'iremboni valve izamuka ikanamanuka mu murongo ugororotse ku ntebe ya valve (ubuso bwo gufunga), igice cyo gufungura no gufunga (irembo) gikoreshwa n'inkingi ya valve.

1. Mbega ukuntuvalve y'iremboikora

Ubwoko bwa valve yo kuzimya yitwa valve y'irembo ikoreshwa mu guhuza cyangwa gukuramo icyuma kiri mu muyoboro. Valve y'irembo ifite uburyo bwinshi butandukanye. Valve z'irembo zikoreshwa cyane zikorerwa mu Bushinwa zifite imikorere ikurikira: igitutu cya nominel PN1760, ingano ya nominel DN151800, n'ubushyuhe bw'akazi t610°C.

2. Ibirangavalve y'irembo

① Akamaro k'ingufu zo mu irembo

A. Nta bushobozi buke bwo guhangana n'amazi. Iyi mashini ntabwo ihindura icyerekezo cy'amazi iyo inyuze muri valve y'irembo kuko umuyoboro w'amazi uri mu gice cy'irembo uba ugororotse, ibyo bikaba bigabanya ubushake bwo guhangana n'amazi.

B. Nta bushobozi buke bwo gufunga no gufungura. Ugereranyije na vali y'umubumbe, gufungura no gufunga vali y'irembo ntibigabanya imbaraga kuko icyerekezo cy'inzira y'irembo kiba giteganye n'icyerekezo cy'inzira.

C. Icyerekezo cy'amazi mu buryo bw'amashanyarazi nta mbogamizi kirimo. Kubera ko amazi ashobora gutembera mu cyerekezo icyo ari cyo cyose aturutse ku mpande zombi z'irembo, ashobora kugera ku ntego yagenewe kandi akwiriye cyane imiyoboro aho icyerekezo cy'amazi mu buryo bw'amashanyarazi gishobora guhinduka.

D. Ni imiterere migufi. Uburebure bw'imiterere ya valve y'umubumbe ni bugufi ugereranyije n'iya valve y'irembo kuko disiki ya valve y'umubumbe ishyizwe mu buryo butambitse mu gice cy'umubiri wa valve mu gihe valve y'umuryango wa valve y'irembo ishyizwe mu gice cy'umubiri wa valve.

E. Ubushobozi bwo gufunga neza. Ubuso bwo gufunga ntibugabanuka cyane iyo bufunguye neza.

② Ingaruka mbi za valve y'irembo

A. Biroroshye kwangiza ubuso bwo gufunga. Ubuso bwo gufunga bw'irembo n'intebe ya valve bigira ibibazo iyo bifunguye kandi bigafunga, ibyo bikaba byangirika byoroshye kandi bigabanya imikorere yo gufunga n'igihe cyo kubaho.

B. Uburebure ni bwinshi kandi igihe cyo gufungura no gufunga ni kirekire. Inzira y'icyuma cyo gufunga ni nini, hakenewe umwanya runaka wo gufungura, kandi ingano y'inyuma ni ndende kuko valve y'irembo igomba kuba ifunguye neza cyangwa ifunze neza mu gihe cyo gufungura no gufunga.

Imiterere igoye, inyuguti ya C. Ugereranyije na value y'umubumbe, hari ibice byinshi, biragoye kuyikora no kuyibungabunga, kandi ihenda cyane.

3. Imiterere y'imvange y'irembo

Igice cy'agapfunyika, agapfunyika cyangwa agapfunyika, agapfunyika ka valve, agapfunyika k'agapfunyika, isahani y'irembo, intebe y'agapfunyika, uruziga rwo gupakira, gufunga, agapfunyika ko gupakira, n'igikoresho cyo kohereza amakuru bigize igice kinini cy'agapfunyika k'irembo.

Valve yo gufunga (valve yo guhagarika) ishobora guhuzwa ku buryo bungana ku miyoboro y’amazi yinjira n’ayo gusohokera iruhande rw’imvange nini cyangwa ifite umuvuduko mwinshi kugira ngo igabanye imbaraga zo gufungura no gufunga. Fungura valve yo gufunga mbere yo gufungura valve y’irembo mugihe ukoresha kugira ngo ungane umuvuduko ku mpande zombi z’irembo. Umurambararo wa valve yo gufunga ni DN32 cyangwa irenga.

① Igice cy'umuyoboro w'amashanyarazi, ugizwe n'igice cy'umuyoboro w'amazi unyuramo hagati, ukaba ari wo mutwe w'ingenzi w'umuyoboro w'amashanyarazi, gifatanye neza n'umuyoboro cyangwa (ibikoresho). Ni ingenzi cyane mu gushyira intebe y'umuyoboro mu mwanya wayo, gushyiraho umupfundikizo w'umuyoboro, no guhuza umuyoboro. Uburebure bw'icyumba cy'umuyoboro w'amashanyarazi ni bunini cyane kuko irembo rifite ishusho ya disiki, rihagaze kandi rizamuka rikanamanuka, rigomba kwinjira mu gice cy'umuyoboro w'amashanyarazi. Igitutu cy'umuyoboro w'amashanyarazi ahanini kigena uburyo igice cy'umubiri w'umuyoboro w'amashanyarazi giteye. Urugero, igice cy'umuyoboro w'amashanyarazi w'umuyoboro w'amashanyarazi gishobora kunanurwa kugira ngo kigire uburebure bwacyo bugufi.

Mu gice cy'imashini, inzira nyinshi ziciriritse zifite igice cy'uruziga. Gufunga ni uburyo bushobora no gukoreshwa ku mavali y'irembo afite umurambararo munini kugira ngo agabanye ingano y'irembo, imbaraga zo gufungura no gufunga, ndetse n'imbaraga. Iyo hakoreshejwe gufunga, imbaraga z'amazi muri vali ziriyongera, bigatuma umuvuduko ugabanuka kandi ikiguzi cy'ingufu kikiyongera. Bityo rero, igipimo cyo kugabanya umuyoboro ntikigomba kuba kinini. Inguni y'umuyoboro ugabanya umuyoboro ku murongo wo hagati ntigomba kurenza 12°, kandi igipimo cy'umurambararo w'umuyoboro w'intebe ya vali ku murambararo wayo rusange gikwiye kuba hagati ya 0.8 na 0.95.

Isano riri hagati y'umubiri wa valve n'umuyoboro, ndetse n'umubiri wa valve n'agasanduku, rigenwa n'imiterere y'umubiri wa valve y'irembo. Gusudira, gusuka, gusuka, no gusudira plaque y'imiyoboro ni amahitamo yo gukaraba umubiri wa valve. Ku ngano iri munsi ya DN50, akenshi hakoreshwa imiyoboro ya valve, imiyoboro ya valve isanzwe ikoreshwa, imiyoboro ya valve isanzwe ikoreshwa, imiyoboro ya valve isanzwe ikoreshwa mu gusuka ibintu bifatika bidahuye n'ibipimo, kandi imiterere ya valve isanzwe irashobora gukoreshwa. Imiyoboro ya valve isanzwe ikoreshwa mu gusuka ifite ibibazo mu buryo rusange bwo gusuka.

②Umupfundikizo wa valve ufite agasanduku ko gushyiramo ibintu kandi ufatanye n'umubiri wa valve, bigatuma uba igice cy'ingenzi cy'icyumba cy'umuvuduko gitwara umuvuduko. Umupfundikizo wa valve ufite ibice bishyigikira ubuso bw'imashini, nk'imbuto z'umugongo cyangwa uburyo bwo kohereza, ku mpande zombi z'umurambararo wo hagati n'uwo hasi.

③Inkoko y'umugongo cyangwa ibindi bice by'igikoresho gitanga ubutumwa bishyigikiwe n'agakingirizo, gafatanye n'agakingirizo.

④Urufatiro rwa valve rufatanye neza n'igiti cy'umugozi cyangwa igikoresho cyo kohereza. Igice cy'inkoni ishaje n'aho ipakira bikora ibice bibiri bifunga, bishobora kohereza imbaraga no kugira uruhare mu gufungura no gufunga irembo. Dukurikije aho umugozi uri ku gice cy'umugozi, valve y'irembo ry'umugozi n'irembo ry'irembo ryihishe biratandukanye.

A. Valve y'irembo ry'umugongo izamuka ni iyo ifite umugozi wo kohereza ibintu uherereye hanze y'umubiri wayo kandi umugozi wayo wa valve ushobora kuzamuka no kumanuka. Umugozi w'umugongo uri ku gipfundikizo cyangwa ku iboneti ugomba kuzunguruka kugira ngo uzamure umugozi w'umugongo. Umugozi w'umugongo n'umugozi w'umugongo ntibihura n'icyo gipfundikizo bityo ntibigira ingaruka ku bushyuhe n'ingese by'icyo gipfundikizo, bigatuma bikundwa. Umugozi w'umugongo ushobora kuzunguruka gusa nta kwimuka hejuru no hasi, ibyo bikaba ingirakamaro mu gutuma umugozi w'umugongo ...

B. Ibyuma by'irembo ry'umukara bifite umugozi wo kohereza amakuru uherereye mu mwobo w'umubiri hamwe n'umugozi w'irembo uzenguruka. Kuzunguruka umugozi w'irembo bituma umugozi w'irembo ujya ku isahani y'irembo, bigatuma umugozi w'irembo uzamuka ukagwa. Umugozi w'irembo ushobora kuzunguruka gusa, ntuzamuke cyangwa ngo umanukane. Ibyuma biragoye kubyifatamo kubera uburebure bwabyo buto kandi bigoye gufungura no gufunga. Ibipimo bigomba gushyirwamo. Bikwiriye ahantu hatangiza kandi hari ikirere kibi kuko ubushyuhe n'ihungabana ry'umugozi w'irembo bigira ingaruka ku mikoranire hagati y'umugozi w'irembo n'umugozi w'irembo n'umugozi.

⑤Igice cya kinematic pair gishobora gushyirwa ku gikoresho gikwirakwiza amakuru n'imbaraga zo kohereza amakuru kigizwe n'umugozi w'ingufu za valve n'itsinda ry'umugozi w'ingufu za valve.

⑥Uduti twa valve cyangwa igiti gishobora guhabwa ingufu z'amashanyarazi, imbaraga z'ikirere, imbaraga za hydraulic, n'umurimo binyuze mu gikoresho gitanga ingufu. Gutwara amashanyarazi kure mu nganda zitanga ingufu akenshi bikoresha amapine y'intoki, ibifuniko bya valve, ibice bitanga ingufu, imigozi ihuza, n'imigozi ihuza abantu bose.

⑦Intebe ya valve Gufunga, gusudira, guhuza imigozi, n'ubundi buryo bukoreshwa kugira ngo intebe ya valve ifatanye n'umubiri wa valve kugira ngo ibashe gufunga n'irembo.

⑧Bitewe n'ibyo umukiriya akeneye, impeta yo gufunga ishobora gushyirwa ku mubiri wa valve kugira ngo habeho ubuso bwo gufunga. Ubuso bwo gufunga bushobora kandi gusukurwa ku mubiri wa valve hakoreshejwe valve zikozwe mu bikoresho nk'icyuma gishongeshejwe, icyuma kidashonga cya austenitic, na aloi y'umuringa. Kugira ngo hirindwe ko ubu buryo buva ku gice cy'urufatiro rwa valve, gupakira bishyirwa mu gasanduku ko gupfunyikamo (agasanduku ko gupfunyikamo).
