Pneumatic Share Control Valve: Rererey Wothandizira Madzi oyenda

Pamunda wa ndondomeko ya mafakitale, valavu imodzi yolamulira ndi chipangizo chofunikira kwambiri chomwe chimapangitsa kuti madzi otuluka, kupsinjika, ndi kutentha, kuonetsetsa kukhazikika kwa njira.

Kapangidwe ka valavu iyi ndi yophatikizika, yopangidwa ndi thupi la valavu, pulagi imodzi, valavu, woyambitsa seaphragm, wogwira ntchito. Woyeserera wa diaphragm ndiye gulu loyendetsa valve, kutembenuza zizindikiro za chibayo (nthawi zambiri 0.02-0.1m) ku magetsi. Pulogalamu ya valavu imalumikizidwa ndi wochita setiototor kudzera pa stem ya valavu, ndipo malo ake m'chipindacho chimatsimikizira kukula kwa gawo.

Chizindikiro cha chibayo chikalowa cholowa ku seaphragm, wochita secrutor amapanga njira yolingana yomwe imayendetsa stem stem ndi valavu kuti musunthire kapena pansi. Ngati chizindikiro cha chizindikirocho chikuwonjezeka, pulagi ya valavu imachoka pampando wa valavu, ndikukulitsa malo oyenda ndikulola kuti madzi ambiri adutse. Mosiyana, kuchepa kwa chizindikirocho kumapangitsa plug ya valavu yoti isunthire pampando wa valavu, kuchepetsa malo ndikuletsa kuyenda kwamadzi. Ubwenzi wapakati pa chibayo ndi digiri yotseguka ya valavu imathandizira kuwongolera kolondola kwa madzi otsika.

Mavavu amodzi owongolera mipando amagwiritsidwa ntchito kwambiri m'mafakitale monga ukadaulo wamankhwala, mankhwala opatsirana, chakudya ndi chakumwa, ndi mankhwalawa. Amakhala oyenera kwambiri kwa machitidwe okhala ndi zovuta zapakatikati komanso zazing'ono kwa mitengo yaying'ono yoyenda, pomwe mawonekedwe amodzi amapereka magwiridwe antchito abwino, ndikuchepetsa kutaya. Kuphatikiza apo, liwiro lawo limathamanga kwambiri, ndikuwonetsetsa kuti kusintha kwa nthawi kusintha kwa kusintha kwa magawo.

Chimodzi mwazinthu zabwino kwambiri za valavu iyi ndi kuwongolera kwake kwakukulu, komwe kumatha kukwaniritsa zofunikira za mafakitale osiyanasiyana. Ilinso ndi kapangidwe kambiri, kumapangitsa kuti ikhale yosavuta kukhazikitsa, kusungitsa, ndi calibrate. Kuphatikiza apo, kugwiritsa ntchito kwa chibayo kumapangitsa kuti ikhale yotetezeka kugwiritsa ntchito malo ophukira, chifukwa palibe chiopsezo cha magetsi.

Valain imodzi yolamulira ya pampando, yomwe ili ndi luso lokhalokha ndikugwiritsa ntchito zodalirika, zimagwira ntchito yopanda mphamvu m'magulu a mafakitale, zimathandizira kwambiri pakutha kwazopanga komanso kusintha kwa malonda.
