A iremboni valve izamuka ikamanuka kumurongo ugororotse ugana intebe ya valve (hejuru yikimenyetso), hamwe no gufungura no gufunga igice (irembo) rikoreshwa nigiti cya valve.

1. Icyo airemboikora

Ubwoko bwo gufunga valve bwitwa irembo ryakoreshejwe muguhuza cyangwa guhagarika imiyoboro mumiyoboro. Irembo ry'irembo rifite imikoreshereze myinshi itandukanye. Ibirindiro bikoreshwa cyane mumarembo bikozwe mubushinwa bifite imikorere ikurikira: umuvuduko w'izina PN1760, ubunini bw'izina DN151800, n'ubushyuhe bwo gukora t610 ° C.

2. Ibiranga airembo

Inyungu za valve valve

Igisubizo. Ikigereranyo ntigihindura icyerekezo cyacyo iyo kinyuze mumarembo yumuryango kuva umuyoboro uciriritse imbere mumarembo ya valve umubiri ugororotse, bigabanya kurwanya amazi.

B. Hano harikibazo gito mugihe cyo gufungura no gufunga. Ugereranije nukuvugana na valve yisi, gufungura no gufunga irembo ryirembo ntabwo bigabanya akazi cyane kuko icyerekezo cyimikorere y amarembo kinyuranye nicyerekezo gitemba.

C. Icyerekezo cyo kugendana icyerekezo ntigabanijwe. Kubera ko imiyoboro ishobora gutembera mu cyerekezo icyo aricyo cyose uhereye kumpande zombi z'irembo, irashobora gukora intego igenewe kandi ikwiranye n'imiyoboro aho icyerekezo cy'itangazamakuru gishobora guhinduka.

D. Nuburyo bugufi. Uburebure bwububiko bwa globe ni bugufi kurenza ubw'irembo ry'irembo kubera ko disiki ya globe ya globe ihagaze mu buryo butambitse mu mubiri wa valve mu gihe irembo ry'irembo ry'irembo ryashyizwe mu buryo buhagaritse mu mubiri wa valve.

E. Ubushobozi bwo gufunga neza. Ubuso bwa kashe ntibwangiritse iyo bufunguye byuzuye.

Ibibi byo kumarembo

Igisubizo. Biroroshye kwangiza hejuru yikidodo. Ubuso bwo gufunga irembo hamwe nintebe ya valve bigira ubushyamirane ugereranije iyo bifunguye kandi bifunze, byangiritse byoroshye kandi bigabanya imikorere ya kashe hamwe nigihe cyo kubaho.

B. Uburebure ni bwinshi kandi igihe cyo gufungura no gufunga ni kirekire. Inzira ya plaque nini nini, umwanya munini urakenewe kugirango ufungure, kandi igipimo cyinyuma ni kinini kuko valve y irembo igomba gukingurwa cyangwa gufungwa byuzuye mugihe cyo gufungura no gufunga.

Imiterere igoye, inyuguti C. Ugereranije na valve yisi, hariho ibice byinshi, biragoye gukora no kubungabunga, kandi bisaba byinshi.

3. Kubaka amarembo

Umubiri wa valve, bonnet cyangwa bracket, stem stem, valve stem nut, isahani y irembo, intebe ya valve, uruziga rwo gupakira, gupakira kashe, gupakira gland, hamwe nibikoresho byohereza bigizwe nubwinshi bwurugi.

Umuyoboro wa bypass (guhagarika valve) urashobora guhuzwa ugereranije numuyoboro winjira no gusohoka kuruhande rwa diameter nini cyangwa umuvuduko mwinshi wamarembo kugirango ugabanye itara ryo gufungura no gufunga. Fungura bypass mbere yo gufungura irembo mugihe ukoresha kugirango ugereranye igitutu kumpande zombi. Bypass valve ya diameter nominal ni DN32 cyangwa irenga.

Body Umubiri wa valve, ugize igice cyikorera umuvuduko wumuyoboro uciriritse kandi niwo mubiri nyamukuru wurugi rwinjiriro, uhujwe neza numuyoboro cyangwa (ibikoresho). Nibyingenzi gushira intebe ya valve mumwanya, gushiraho igifuniko cya valve, no guhuza umuyoboro. Uburebure bwicyumba cyimbere cyimbere ni kinini kuko irembo rimeze nka disiki, rihagaritse kandi rizamuka hejuru, rikeneye guhuza mumubiri wa valve. Umuvuduko wizina ugena ahanini uburyo umubiri wa valve wambukiranya. Kurugero, umuvuduko ukabije w irembo rya valve umubiri wa valve urashobora gutunganywa kugirango ugabanye uburebure bwimiterere.

Mu mubiri wa valve, ubwinshi bwinzira ziciriritse zifite uruziga rwambukiranya. Shrinkage nubuhanga bushobora no gukoreshwa kumatara yumuryango ufite diameter nini kugirango ugabanye ubunini bw irembo, imbaraga zo gufungura no gufunga, hamwe na torque. Iyo kugabanuka gukoreshwa, kurwanya amazi muri valve byiyongera, bigatera umuvuduko ukabije nigiciro cyingufu. Ikigereranyo cyo kugabanuka k'umuyoboro ntigomba kuba ikabije. Busbar yumuyoboro ugenda ugabanuka kumurongo wo hagati ntugomba kurenza 12 °, kandi ikigereranyo cyumurambararo wumuyoboro wa valve na diameter yacyo kigomba kuba hagati ya 0.8 na 0.95.

Isano iri hagati yumubiri wa valve numuyoboro, kimwe numubiri wa valve na bonnet, bigenwa nimiterere yumuryango wa valve. Gukora, guhimba, guhimba gusudira, gusudira, hamwe no gusudira isahani ya plaque byose ni amahitamo yo gukomera kumubiri. Kubijyanye na diametero munsi ya DN50, imibiri ya casting isanzwe ikoreshwa, imibiri ya valve yahimbwe ikoreshwa muburyo busanzwe, imashini zometseho imashini zikoreshwa muburyo bwo guteranya ibintu bitujuje ibisobanuro, kandi ibikoresho byo gusudira nabyo birashobora gukoreshwa. Imibiri ihimbwe-isudira yimibiri ikoreshwa mububiko bufite ibibazo nibikorwa rusange byo guhimba.

Cover Igifuniko cya valve gifite agasanduku kuzuyemo kandi kifatanije numubiri wa valve, bigatuma kiba igice kinini cyumuvuduko wicyumba cyumuvuduko. Igifuniko cya valve gifite ibikoresho byimashini ishigikira ibice, nkibiti byimbuto cyangwa uburyo bwo kohereza, kubirindiro bito na bito bya diameter.

NutIbiti by'ibiti cyangwa ibindi bigize igikoresho cyo kohereza bishyigikiwe na bracket, ifatanye na bonnet.

StemIkibaho cya valve gihujwe mu buryo butaziguye nimbuto cyangwa igikoresho cyohereza. Igice cy'inkoni gisennye hamwe no gupakira bigizwe na kashe, ishobora kohereza itara kandi ikagira uruhare rwo gufungura no gufunga irembo. Ukurikije umwanya wurudodo kuruti rwa valve, irembo ryurugi rwibiti hamwe na valve yihishe yikibaho.

A. Irembo ryizamuka ryikariso nimwe murwego rwohereza rwiherereye hanze yumwobo wumubiri kandi uruti rwarwo rushobora kuzamuka hejuru. Ibiti by'uruti kuri bracket cyangwa bonnet bigomba kuzunguruka kugirango uzamure igiti cya valve. Urudodo rwuruti nimbuto zuruti ntizihuza nuburyo bityo ntibigire ingaruka kubushyuhe bwikigereranyo no kwangirika, bigatuma bikundwa. Urubuto rwibiti rushobora kuzunguruka gusa hejuru no hasi kwimurwa, ibyo bikaba byiza muburyo bwo gusiga amavuta ya valve. Gufungura amarembo nabyo birasobanutse.

B. Irembo ryijimye ryijimye rifite urudodo rwihererekanyabubasha ruri imbere mu cyuho cyumubiri hamwe nigiti kizunguruka. Kuzenguruka uruti rwa valve rutwara ibiti byuruti ku isahani y amarembo, bigatuma igiti cya valve kizamuka kandi kigwa. Igiti cya valve gishobora kuzunguruka gusa, ntigishobora kuzamuka hejuru cyangwa hepfo. Umuyoboro uragoye gucunga kubera uburebure bwacyo buto kandi bigoye gufungura no gufunga inkoni. Ibipimo bigomba kubamo. Irakwiranye nuburyo budashobora kwangirika hamwe nibihe hamwe nikirere kitameze neza kubera ko ubushyuhe no kwangirika kwingaruka ziciriritse guhuza imiyoboro yumuti wikibabi nigiti cyimbuto hamwe nuburyo bwo hagati.

HeIgice cya kinematike gishobora guhuzwa neza nigikoresho cyohereza no kohereza torque kigizwe nimbuto ya stem stem hamwe nitsinda ryumutwe wa valve.

StemIkibabi cya valve cyangwa ibiti byimbuto birashobora gutangwa bitaziguye nimbaraga zamashanyarazi, ingufu zo mu kirere, ingufu za hydraulic, nakazi binyuze mubikoresho byohereza. Gutwara intera ndende mu mashanyarazi bikunze gukoresha intoki, igifuniko cya valve, ibice byohereza, guhuza ibiti, hamwe no guhuza isi yose.

Intebe yintebe Kuzunguruka, gusudira, guhuza imigozi, hamwe nubundi buryo bukoreshwa mukurinda intebe ya valve kumubiri wa valve kugirango ishobore gufunga irembo.

E Ukurikije ibyo umukiriya akeneye, impeta ya kashe irashobora kugaragara neza kumubiri wa valve kugirango habeho ubuso bwa kashe. Ubuso bwa kashe burashobora kandi kuvurwa muburyo butaziguye kumubiri wa valve kubibiko bikozwe mubikoresho nkibyuma bikozwe mucyuma, ibyuma bitagira umuyonga wa austenitike, hamwe nu muringa. Kugirango wirinde ko imiyoboro idatemba ku giti cya valve, gupakira bishyirwa imbere mu isanduku yuzuye (agasanduku kuzuza).
