A ahagararavalve ni [1] igororotse inyuze muri valve ifungura ikanafunga byihuse, kandi ikanakoreshwa mubitangazamakuru bifite uduce duto twahagaritswe bitewe ningaruka zo guhanagura kwimuka hagati yikimenyetso cya kashe hamwe nuburinzi bwuzuye bwo kwirinda guhura nigikoresho gitemba iyo gifunguye byuzuye. Ikindi kintu cyingenzi kiranga nuko byoroshye guhuza n'imiyoboro myinshi yubatswe, kugirango valve imwe ibone inzira ebyiri, eshatu, cyangwa enye zitandukanye. Ibi byoroshya igishushanyo cya sisitemu yo kuvoma, igabanya ingano ya valve yakoreshejwe, kandi igabanya amwe mumihuza isabwa mubikoresho.
Uburyo ikora Valves hamweahagararaimibiri hamwe nu mwobo nko gufungura no gufunga ibice. Gucomeka umubiri uzunguruka hamwe nigiti cya [2] kugirango ugere kubikorwa byo gufungura no gufunga. Gitoya, ipakiwe, plug valve nayo izwi nka "isake". Umubiri wacometse kumacomeka ya valve ahanini ni cone (hariho n'umubiri wa silindrike), ihujwe nubuso bwa orifice hejuru yumubiri wa valve kugirango bibe bifatanye. Gucomeka kumashanyarazi nubwoko bwambere bwa valve yakoreshejwe, hamwe nuburyo bworoshye, gufungura byihuse no gufunga, hamwe no kurwanya amazi make. Amashanyarazi asanzwe yishingikiriza kumikoranire itaziguye hagati yumubiri wicyuma urangije nu mubiri wa valve kugirango ushireho kashe, bityo gufunga ni bibi, imbaraga zo gufungura no gufunga nini, byoroshye kwambara, kandi mubisanzwe birashobora gukoreshwa gusa mumuvuduko muke (utarenze megapascal 1) na diameter nto (munsi ya mm 100).

Ukurikije imiterere yimiterere, irashobora kugabanywamo ubwoko bune: gucomeka neza, gucomeka kwifunga, gucomeka no gushiramo amavuta. Ukurikije imiyoboro y'umuyoboro, irashobora kugabanywamo ubwoko butatu: unyuze mu cyuma gicomeka, inzira-eshatu zihagarara hamwe ninzira enye zicomeka. Hariho kandi imiyoboro ya plaque.
Amacomeka ya plaque yashyizwe mubikorwa ukoresheje harimo: yoroshye ya kashe ya plaque yamashanyarazi, amavuta-yasizwe amavuta akomeye ya kashe ya plaque, poppet plug valve, inzira-eshatu ninzira enye.
Ibyiza
1. Gucomeka kumashanyarazi ikoreshwa mubikorwa kenshi, kandi gufungura no gufunga byihuse kandi byoroshye.
2. Kurwanya amazi ya plug ya valve ni nto.
3. Amacomeka ya plaque afite imiterere yoroshye, ugereranije ntoya, uburemere bworoshye no kuyitaho byoroshye.
4. Imikorere myiza yo gushiraho ikimenyetso.
5. Ntabwo bigarukira ku cyerekezo cyo kwishyiriraho, kandi icyerekezo cyo gutembera hagati gishobora kuba uko bishakiye.
6. Nta kunyeganyega, urusaku ruke.
Irembo ryoroshye-kashe
Irembo ryoroshye rya kashe ya valve, valve yinganda, icyuma cyoroshye cyo gufunga amarembo yo gufungura no gufunga ibice ni impfizi zintama, icyerekezo cyo kugenda kwintama ni perpendicular yerekeza ku cyerekezo cyamazi, valve y irembo irashobora gukingurwa no gufungwa gusa, ntishobora guhinduka no gutabwa. Impfizi y'intama ifite ibibanza bibiri bifunze, uburyo bukoreshwa cyane muburyo bw irembo rya valve ibice bibiri bifunze bifunga uruzitiro, inguni ya wedge iratandukanye nibipimo bya valve, diameter nominal ni DN50 ~ DN1200, ubushyuhe bwo gukora: ≤200 ° C.
Ihame ry'ibicuruzwa
Icyapa cy'iremboiremboe irashobora gukorwa muri rusange, yitwa irembo rikomeye; Irashobora kandi gukorwa mu mpfizi y'intama ishobora kubyara déformasiyo nkeya kugirango irusheho gukora neza kandi ikore neza kugirango itandukane ku mpande zifatika zifatika mugikorwa cyo gutunganya, bita impfizi y'intama.
Ikirango cyoroshyeamarembobigabanijwemo ubwoko bubiri: gufungura inkoniIrembo ryoroshye rya kashe ya valven'inkoni yijimyeirembo. Mubisanzwe hariho urudodo rwa trapezoidal kurubingo rwo guterura, ruhindura icyerekezo cyizunguruka mukigenda cyumurongo unyuze mumitiba hagati yintama hamwe na groove yo kuyobora kumubiri wa valve, ni ukuvuga itara rikora mumikorere ikora. Iyo valve ifunguye, iyo uburebure bwintama bwintama bingana ninshuro 1: 1 diameter ya valve, umuvuduko wamazi ntuburizwamo rwose, ariko iyi myanya ntishobora gukurikiranwa mugihe ikora. Mu mikoreshereze nyayo, irangwa na vertex yuruti, ni ukuvuga, umwanya udashobora gukingurwa, nkumwanya wuzuye wuzuye. Kugirango ubaze gufunga kubera ihinduka ryubushyuhe, mubisanzwe irakingurwa kumwanya wa apex hanyuma igasubira inyuma 1 / 2-1 ihinduka nkumwanya wa valve yuzuye. Kubwibyo, imyanya yuzuye ya valve igenwa numwanya wintama (ni ukuvuga inkoni). Ubu bwoko bwa valve bugomba gushyirwaho muburyo butambitse.
Ibisabwa muri rusange
1. Ibisobanuro n'ibyiciro byaIrembo ryoroshye rya kasheigomba kuba yujuje ibyangombwa byubushakashatsi.
2. Icyitegererezo cyoroshye cya kashe ya rugi valve igomba kwerekana umubare wigihugu usabwa ukurikije. Niba ari uruganda rusanzwe, ibisobanuro bijyanye nurugero bigomba kwerekanwa.
3. Umuvuduko wakazi waIrembo ryoroshye rya kashe ya valvebisaba umuvuduko wakazi wa ≥ umuyoboro, utagize ingaruka ku giciro, umuvuduko wakazi valve ishobora kwihanganira igomba kuba irenze umuvuduko wakazi wumuyoboro, kandi uruhande urwo arirwo rwose rworoshye rwa kashe ya rugi rugomba kuba rushobora kwihanganira inshuro 1.1 agaciro kakazi kakazi ka valve nta kumeneka;
4. Igipimo cyo gukora cyaIrembo ryoroshye rya kashe ya valveigomba kwerekana umubare rusange wigihugu ushingiye kuriwo, kandi niba ari urwego rwumushinga, inyandiko yumushinga igomba kwomekwa kumasezerano yamasoko.
Icya kabiri, ibikoresho byoroshye bya kashe ya valve ibikoresho
1.
2. Ibikoresho by'uruti bigomba guharanira icyuma kitagira umwanda (2CR13), kandi na valve nini ya diameter nayo igomba kuba icyuma kitagira ingese.
3. Ibinyomoro bikozwe mu muringa wa aluminiyumu cyangwa umuringa wa aluminiyumu, kandi ubukomezi n'imbaraga biruta ubw'uruti rwa valve.
4.
5. Ibikoresho byo hejuru
(1) Ubwoko bwa kashe yoroshyeirembos ziratandukanye, kandi uburyo bwo gufunga nibisabwa nibikoresho biratandukanye;
.
.
6. Gupakira ibiti
(1) Kuberako kashe yoroshyeirembomurusobe rwumuyoboro mubusanzwe gufungura no gufunga gake, gupakira birasabwa kuba bidakora mumyaka itari mike, kandi gupakira ntibisaza, kandi ingaruka zo gufunga bikomeza igihe kirekire;
(2) Gupakira valve nabyo bigomba guhoraho mugihe byakorewe gufungura no gufunga kenshi;
(3) Urebye ibisabwa haruguru, gupakira valve shaft iharanira kudasimburwa ubuzima cyangwa imyaka irenga icumi;
(4) Niba gupakira bigomba gusimburwa, igishushanyo mbonera cya pneumatike kigomba gusuzuma ingamba zishobora gusimburwa bitewe n’umuvuduko w’amazi.
Icya gatatu, uburyo bwo gukora bwa kashe yoroshyeirembo
3.1 Icyerekezo cyo gufungura no gufunga icyerekezo cyoroshye cya kashe ya valve mugihe cyo gukora kigomba gufungwa kumasaha.
3.2 Kuberako valve ya pneumatike mumiyoboro ya pipe ikunze gufungurwa no gufungwa, umubare wimpinduramatwara yo gufungura no gufunga ntugomba kuba mwinshi, ni ukuvuga ko valve nini ya diameter nayo igomba kuba muri revolisiyo 200-600.
3.3 Kugirango byorohereze imikorere yo gufungura no gufunga umuntu umwe, urumuri ntarengwa rwo gufungura no gufunga rugomba kuba 240N-m mugihe cyumuvuduko wumuyoboro.
3.4 Gufungura no gufunga ibikorwa byanyuma bya kashe ya kashe yoroheje igomba kuba ifite kare kare, kandi ingano igomba kuba isanzwe, kandi ikareba hasi, kugirango abantu bashobore gukora biturutse kubutaka. Imyanya ifite disiki ya disiki ntabwo ikwiriye gukoreshwa mumiyoboro yo munsi.
3.5 kwerekana icyerekezo cyo gufungura no gufunga urwego rwa kashe yoroshyeirembo
.

.
3.6 Niba irembo ryoroshye rya kashe ya valve yashyinguwe byimbitse, kandi intera iri hagati yuburyo bukoreshwa na panne yerekana nubutaka ni .5 1.5m, igomba kuba ifite ibikoresho byo kwagura inkoni, kandi igomba gukosorwa neza kugirango abantu babashe kwitegereza no gukorera hasi. Nukuvuga ko, gufungura no gufunga imikorere ya valve murusobe rwumuyoboro ntibikwiye kubikorwa byubutaka.
Icya kane, ikizamini cyo gukora kashe yoroshyeirembo
4.1 Iyo valve ikozwe mubice bimwe byihariye, ishyirahamwe ryemewe rigomba gushingwa kugerageza imikorere ikurikira:
(1) Gufungura no gufunga itara rya valve mugihe cyumuvuduko wakazi;
(2) Ukurikije imiterere yumuvuduko wakazi, irashobora kwemeza guhora gufungura no gufunga ibihe byaindangagufunga cyane;
.
4.2indangabigomba kugeragezwa ku buryo bukurikira mbere yo kuva mu ruganda:
(1) Iyo valve ifunguye, umubiri wa valve ugomba kwihanganira ikizamini cyimbere imbere inshuro ebyiri agaciro kakazi ka valve;
.
Icya gatanu, imbere ninyuma yo kurwanya ruswa ya kashe yoroheje ya kashe ya valve
5.1 Imbere no hanze yumubiri wa valve (harimo agasanduku kohereza umuvuduko uhindagurika), mbere ya byose, guturika kurasa, kuvanaho umucanga no kuvanaho ingese bigomba gukorwa, kandi ifu ya epoxy resin idafite uburozi igomba guterwa amashanyarazi, hamwe nubunini burenga 0.3mm. Mugihe bigoye gutera electrostatike gutera epoxy resin idafite uburozi kumibande minini-nini, irangi rya epoxy ridafite uburozi naryo rigomba guhanagurwa no guterwa.
5 Icya kabiri, hejuru iroroshye, kuburyo kurwanya amazi bigabanuka.
5.3. Imiterere yimiti niyumubiri nayo igomba kuba yujuje ibisabwa bijyanye.
