Imininingwane yokusebenza kwe-Steam valve

I-valve yokuphepha ye-steam generator ingenye yezinsiza eziyinhloko zokuphepha ze-steam generator. Ingakwazi ukuvimbela ngokuzenzakalelayo umfutho we-steam we-boiler ukuthi udlule ububanzi obuvunyelwe kusengaphambili, ngaleyo ndlela iqinisekise ukusebenza okuphephile kwe-boiler. Kuyidivayisi yokuphepha yokukhulula ingcindezi ngokweqile.

Isetshenziswa kabanzi empilweni yethu, futhi idlala indima ekuqinisekiseni ukuphepha kokusebenza kwamajeneretha omusi. Imvamisa, ukufakwa, ukulungisa, nokugcinwa kufanele kwenziwe ngokuhambisana nemithethonqubo.

Imininingwane yokusebenza kwe-Steam valve:

1. Ivalvu yokuphepha yesitimu kufanele ifakwe mpo endaweni ephakeme kakhulu yophawu lwentengiso lwe-steam generator kanye nesihloko. Awekho amapayipi akhipha isitimu noma amavalvu azofakwa phakathi kwevalvu yokuphepha nesigubhu noma unhlokweni.

2. I-valve yokuphepha ye-steam yohlobo lwe-lever kufanele ibe nedivaysi yokuvimbela isisindo ukuthi singahambi ngokwaso kanye nomhlahlandlela wokukhawulela ukuchezuka kwe-lever. I-valve yokuphepha yohlobo lwentwasahlobo kufanele ibe nesibambo sokuphakamisa kanye nedivaysi yokuvimbela isikulufu sokulungisa ukuthi singaphenduki nje ngokunganaki.

3. Kumabhayela anomfutho we-steam olinganiselwe ongaphansi noma olingana no-3.82MPa, ububanzi bomphimbo wevalvu yokuphepha yesitimu akufanele kube ngaphansi kuka-25nm; kumabhayela anengcindezi yesitimu elinganiselwe enkulu kuno-3.82MPa, ububanzi bomphimbo wevalvu yokuphepha akufanele ibe ngaphansi kuka-20mm.

4. Indawo ephambanayo yepayipi elixhumayo phakathi kwevalvu yokuphepha yesitimu kanye nebhayela akufanele ibe ngaphansi kwendawo ephambanayo ye-inlet ye-valve yokuphepha. Uma ama-valve amaningana okuphepha efakwe ndawonye epayipini elifushane elixhunywe ngqo kusigubhu, indawo enqamula ingxenye yepayipi elifushane akufanele ibe ngaphansi izikhathi ezi-1.25 endaweni yokukhipha wonke ama-valve okuphepha.

5. Ama-valve okuphepha umusi kufanele ngokuvamile afakwe amapayipi e-exhaust, okufanele aholele ngokuqondile endaweni ephephile futhi abe nendawo eyanele enqamula izingxenye ezithile ukuze kuqinisekiswe ukugeleza okushelelayo kwesitimu sokukhipha umoya. Indawo ephansi yepayipi yokukhipha i-valve yokuphepha kufanele yenziwe sengathi inepayipi lokudonsa elixhunywe endaweni ephephile. Ama-valve awavunyelwe ukufakwa kwipayipi le-exhaust noma ipayipi lokudonsa.

6. Amabhola anamandla okuhwamuka alinganiselwe angaphezu kuka-0.5t/h kufanele afakwe okungenani amavalvu okuphepha amabili; ama-boilers anesilinganiso sokuhwamuka esilinganiselwe esingaphansi noma esilingana no-0.5t/h kufanele afakwe okungenani ivalvu eyodwa yokuphepha. Amavalvu okuphepha kufanele afakwe lapho kuphuma khona i-economizer ehlukanisekayo kanye nokuphuma kwe-steam superheater.

7. I-valve yokuphepha ye-steam yomkhumbi wokucindezela ifakwe kangcono ngokuqondile endaweni ephakeme kakhulu yomzimba womkhumbi wokucindezela. Ivalvu yokuphepha yethangi lokugcina igesi eliwuketshezi kufanele ifakwe esigabeni segesi. Ngokuvamile, ipayipi elifushane lingasetshenziswa ukuxhuma esitsheni, futhi ububanzi bepayipi elifushane le-valve yokuphepha akufanele libe lincane kunobubanzi be-valve yokuphepha.

8. Amavalvu ngokuvamile awavunyelwe ukufakwa phakathi kwamavalvu okuvikela umusi neziqukathi. Eziqukathi ezinemithombo evuthayo, eqhumayo noma e-viscous, ukuze kube lula ukuhlanzwa noma ukushintshwa kwe-valve yokuphepha, i-valve yokumisa ingafakwa. Le valve yokumisa kufanele ifakwe phakathi nokusebenza okujwayelekile. Ivulwe ngokugcwele futhi ivalwe ukuvimbela ukuphazamisa.

9. Ngemikhumbi yokucindezela enemidiya evuthayo, eqhumayo noma enobuthi, imidiya ekhishwa i-valve yokuphepha yesitimu kufanele ibe nemishini yokuphepha kanye nezinhlelo zokubuyisela. Ukufakwa kwe-valve yokuphepha ye-lever kumele kugcine indawo eqondile, futhi i-valve yokuphepha yasentwasahlobo iphinde ifakwe kahle kakhulu ukuze igweme ukuthinta isenzo sayo. Ngesikhathi sokufakwa, ukunakwa kufanele futhi kukhokhwe ukulingana, i-coaxiality yezingxenye, nokucindezeleka okufanayo ku-bolt ngayinye.

10. Amavalvu okuvikela umusi asanda kufakwa kufanele ahambisane nesitifiketi somkhiqizo. Ngaphambi kokufaka, kufanele zilinganiswe kabusha, zivalwe futhi zikhishwe ngesitifiketi sokulinganisa i-valve yokuphepha.

11. I-outlet ye-valve yokuphepha ye-steam akufanele ibe nokumelana nokugwema ukucindezela emuva. Uma ipayipi yokukhipha ifakiwe, ububanzi bayo bangaphakathi kufanele bube bukhulu kunobubanzi bokuphuma kwe-valve yokuphepha. Indawo yokukhipha i-valve yokuphepha kufanele ivikelwe emakhazeni. Ayifanele isiqukathi esivutha umlilo noma esinobuthi noma esinobuthi obukhulu. Eziqukathi zemidiya, ipayipi elikhiphayo kufanele lixhunywe ngokuqondile endaweni engaphandle ephephile noma libe nezinsiza zokulahla ngendlela efanele. Awekho ama-valve avunyelwe epayipini lokukhipha.

12. Akukho valvu okufanele ifakwe phakathi kwezinto ezithwala umfutho kanye nevalvu yokuphepha yesitimu. Eziqukathi eziphethe imidiya evuthayo, eqhumayo, enobuthi noma i-viscous, ukuze kube lula ukushintshwa nokuhlanza, i-valve yokumisa ingase ifakwe, futhi ukwakheka kwayo nosayizi wobubanzi akumele kuhluke. Kufanele kuvimbe ukusebenza okuvamile kwe-valve yokuphepha. Ngesikhathi sokusebenza okuvamile, i-valve yokumisa kufanele ivuleke ngokugcwele futhi ivalwe.
