Valavu yochepetsera kupanikizika imatanthawuza valavu yomwe imachepetsa mphamvu yolowera kumalo olowera kuti ifike kumtunda wofunikira podutsa pa diski ya valve, ndipo imatha kugwiritsa ntchito mphamvu yapakati pawokha kuti mphamvu yotuluka ikhale yosasinthika pamene kuthamanga ndi kutuluka kwa mpweya kumasintha.
Malingana ndi mtundu wa valavu, kuthamanga kwa kutuluka kumatsimikiziridwa ndi kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka valve pa valve kapena ndi sensor yakunja. Ma valve ochepetsa kupanikizika amagwiritsidwa ntchito kwambiri m'nyumba zogona, zamalonda, zamakampani ndi mafakitale.
Kuwunika kwa ma valve ochepetsa kuthamanga-mawonekedwe ofunikira pakuwunika
Kuwunika kwapamwamba kwapamwamba kwa valve yochepetsera kuthamanga
Valavu yochepetsera kuthamanga sikuyenera kukhala ndi zolakwika monga ming'alu, kutsekeka kozizira, matuza, pores, mabowo a slag, shrinkage porosity ndi oxidation slag inclusions. Kuwunika kwapamwamba kwa ma valve kumaphatikizapo kuyang'anira gloss, flatness, burrs, scratches, oxide layer, ndi zina zotero. Kuyenera kuchitidwa pamalo owala bwino ndikugwiritsa ntchito.
zida zowunikira akatswiri pamwamba.
Malo osakhala opangidwa ndi valavu yochepetsera kuthamanga ayenera kukhala yosalala komanso yosalala, ndipo chizindikiro choponyera chiyenera kukhala chomveka. Pambuyo poyeretsa, kuthira ndi kukweza kuyenera kusungunuka ndi pamwamba pa kuponyera.
Kuchepetsa mphamvu ya valve kukula ndi kuwunika kulemera
Kukula kwa valavu kumakhudza mwachindunji kutsegula ndi kutseka kwa valve ndi ntchito yosindikiza. Chifukwa chake, pakuwunika mawonekedwe a valve, kukula kwa valve kumayenera kuyang'aniridwa mosamalitsa. Kuyang'ana kwa dimensional kumaphatikizaponso kuyang'ana m'mimba mwake, kutalika, kutalika, m'lifupi, ndi zina zotero.
Kuwunika kwa ma valve ochepetsa kuthamanga
Kuwunika kwa mawonekedwe a valve yochepetsera kupanikizika kumafuna kuyang'anitsitsa chizindikiro cha valve, chomwe chiyenera kukwaniritsa zofunikira zazitsulo zopangira valve. Chizindikirocho chiyenera kukhala chomveka bwino komanso chosavuta kugwa. Yang'anani chizindikiro cha valve yochepetsera kuthamanga. Thupi la valavu liyenera kukhala ndi zida za valve, kukakamiza mwadzina, kukula kwadzina, nambala yang'anjo yosungunuka, njira yoyendetsera, ndi chizindikiro; nameplate iyenera kukhala ndi media yogwira ntchito, kuchuluka kwa kuthamanga kwa inlet, kuchuluka kwa kutulutsa, ndi dzina la wopanga. Mafotokozedwe a zitsanzo, tsiku lopangidwa.
Kuwunika kwapang'onopang'ono kwa ma valve box label color box kuyendera
Ma valve ochepetsera mphamvu ayenera kuikidwa musanachoke ku fakitale kuti ateteze ma valve kuti asawonongeke panthawi yoyendetsa ndi kusunga. Kuyang'anira mawonekedwe a valve yochepetsera kuthamanga kumafuna kuyang'anitsitsa chizindikiro cha bokosi la valve ndi kuyika bokosi lamtundu.
Kuwunika kwa ma valve ochepetsa kupanikizika-kuwunika magwiridwe antchito
Kuchepetsa kuthamanga kwa ma valve kuwongolera magwiridwe antchito
Mkati mwa mayendedwe operekedwa, mphamvu yotulutsa imayenera kusinthidwa mosalekeza pakati pa mtengo wapamwamba ndi mtengo wocheperako, ndipo pasakhale chotchinga kapena kugwedezeka kwachilendo.
Kuwunika kwa mawonekedwe a ma valve ochepetsa kuthamanga
Pamene kutuluka kwa kutuluka kumasintha, valavu yochepetsera kuthamanga sikuyenera kukhala ndi zochitika zosazolowereka, ndipo kutayika kolakwika kwa mphamvu yake yotuluka: kwa ma valve ochepetsera molunjika, sikuyenera kukhala kwakukulu kuposa 20% ya kuthamanga kwa kutuluka; kwa mavavu ochepetsa kuthamanga kwa oyendetsa ndege, sikuyenera kupitilira 10% ya mphamvu yakutuluka.
Kuyang'ana makhalidwe a kuthamanga kwa valve kuchepetsa kuthamanga
Kuthamanga kolowera kukasintha, valavu yochepetsera kuthamanga sikuyenera kukhala ndi kugwedezeka kwachilendo. Kutsika kwake kwapang'onopang'ono kwapang'onopang'ono: kwa ma valve ochepetsa kuthamanga kwachindunji, sikuyenera kukhala kwakukulu kuposa 10% ya kuthamanga kwa kutuluka; kwa oyendetsa-oyendetsedwa ndi mavavu ochepetsa kuthamanga, sikuyenera kupitirira 5% ya kuthamanga kwa kutuluka.
| Kukula kwa ntchito DN | Kutsika kwakukulu kwa voliyumu (mathovu)/min |
| ≤50 | 5 |
| 65-125 | 12 |
| ≥150 | 20 |
Chisindikizo chokwera chokwera chamagetsi otulutsa mpweya chiyenera kukhala zero zitsulo - chisindikizo chachitsulo sichiyenera kupitirira 0.2MPa/min.
kupitiriza kugwira ntchito
Pambuyo pakuyesa kosalekeza kwa opareshoni, imatha kukumanabe ndi magwiridwe antchito komanso zoyendera.
