Anthu ambiri amadabwa kuti valve yodzilamulira yokha ndi chiyani. M'malo mwake, valavu yodzilamulira yokha imadalira kupanikizika kwa sing'anga yomwe ikuyenda kudzera mu valve yokha, ndipo kutentha kumakhala ngati gwero la mphamvu.
Valavu imagwira ntchito yokha popanda magetsi akunja ndi chida chachiwiri. Ndiye kodi valavu yodziyendetsa yokha ndi yotani?
1. Njira yogwiritsira ntchito
Ma valve odziyendetsa okha amadalira magetsi a digito omwe akuyenda kudzera mu sing'anga yokha mu intaneti. Celsius imagwiritsidwa ntchito ngati valavu yosuntha m'dera la mphamvu kuti igwire ntchito yokha. Mphamvu zamagetsi zakunja ndi ziwiri ndizofunikira.
Sekondale zida. Valavu yodzilamulira iyi imagwiritsa ntchito gwero la reverse sign (digital pressure gauge, differential pressure. Celsius) kumapeto kwa valavu kuti itumize ku bungwe la opareshoni kudzera mu chubu choyambira chizindikiro.
Disiki yoyendetsa galimoto imasintha kutsegulira kwa valve kuti isinthe mawonekedwe a digito, kuthamanga kwa mafunde ndi Celsius. Valve yowongolera imatha kugawidwa kukhala ntchito zolunjika komanso zosalunjika.
Mitundu iwiri.
Direct function self-operated control valve, yomwe imadziwikanso kuti mtundu wodzaza masika, imakhala ndi zigawo zotanuka monga masika, mavuvu, mavuvu, mapaketi a kutentha, ndi zina zotero.
Mfundo yoyezera pakati pa mphamvu yamphamvu ndi gwero lazizindikiro za mayankho ndikuti ngati valavu yowongolera ya digito ya eyeball_type regulating valve ikugwiritsidwa ntchito, gwero lazizindikiro ndi choyezera cha digito pakutuluka kwa valve.
Mapaipi oyambira amalowetsedwa mu bungwe logwira ntchito. Ngati valavu yodziyendetsa yokha ikugwiritsidwa ntchito, pali mbale ya orifice (kapena chipangizo china chotsutsana ndi jamming) pamtunda wa valve kuti muchotse kupanikizika kuchokera kumalekezero onse a mbale ya orifice.
Gwero lachidziwitso chosiyanitsidwa limalowetsedwa mu bungwe logwira ntchito. Ngati maukonde odzilamulira okha ndi a digiri ya Celsius, kutuluka kwa valavu kumakhala ndi sensa ya Celsius (kapena chipinda cha kutentha) kudzera pakuyambitsa sensa ya Celsius.
Gulu logwira ntchito lokulitsa matenthedwe ndi contraction drive.
2.Kuyika Notes
(1) malo oponderezedwa ayenera kukhala pamalo oyenera a valve yoyendetsera mphamvu. Kupsyinjika kuyenera kukhala kwakukulu kuposa 2 kuwirikiza kwa chitoliro pamaso pa valavu, ndipo kuthamanga pambuyo pa valve kuyenera kukhala kwakukulu kuposa 6 kuwirikiza kwake kwa chitoliro.
(2) Malinga ndi kuwerengera, valavu ya diso ikhoza kukhala yaying'ono kuposa ya payipi, pamene valavu yapadziko lonse lapansi, valavu ya mpira, valavu yodutsa ndi fyuluta sizingakhale zazing'ono kuposa izo. wa pipeline.
Chidule cha chidziwitso chomwe chili pamwambachi chokhudza momwe valavu yoyendetsera maso imagwirira ntchito, ndikukhulupirira kuti mwaphunzira zambiri mutayang'ana.
Chidziwitso ndi chothandiza kwambiri kwa anthu ambiri, ndiye tiyeni tiwone.
