Opanga Madzi Owongolera Mavavu

Ma valve oyendetsa madzi ndi valavu yoyendetsera madzi, yomwe imapangidwa ndi valavu yaikulu ndi njira yake yolumikizira, valavu yoyendetsa, valavu ya singano, valve ya mpira ndi kupima kuthamanga. Malingana ndi cholinga chogwiritsira ntchito, ntchito ndi malo, zikhoza kusinthidwa kukhala valavu yoyandama yakutali, valavu yochepetsera kuthamanga, valavu yotsegula pang'onopang'ono, valve yoyendetsa kayendedwe kake ndi valavu yothandizira. Ma valve ogwirira ntchito amadzi nthawi zambiri amakhala pamalo abwino, nthawi zambiri amakhala otseguka komanso oyandama. Zimadalira makamaka kusintha pakati pa valavu yaikulu ndi valavu ya singano kapena valavu yoyendetsa ndege kuti azitha kuyendetsa madzi.

Valavu yoyang'anira ma hydraulic ndi valavu yomwe imagwiritsa ntchito kuthamanga kwa madzi mu netiweki ya chitoliro kuwongolera kutseguka, kutseka ndi kutsegulira kwa valavu. Vavu yowongolera madzi imayendetsedwa ndi kusiyana kwapakati △ p pakati pa kumtunda ndi kumunsi kwa payipi. dongosolo ndi kulamulidwa ndi valavu woyendetsa kuti diaphragm (piston) hydraulically opareshoni m'njira yosiyana ndi kulamulidwa mokwanira ndi mphamvu hayidiroliki, kotero kuti valavu yaikulu valavu chitseko kutsegulidwa kwathunthu, kutsekedwa kwathunthu kapena mu boma lolamulidwa. Pamene mpweya woponderezedwa umalowa m'chipinda chowongolera pamwamba pa diaphragm (piston) umatulutsidwa kumlengalenga kapena kumunsi kwapansi-pansi-pansi, kupanikizika kwapadera komwe kumagwira pansi pa diski ya valve ndi pansi pa diaphragm ndi yaikulu kuposa kupanikizika pamwamba, ndipo chimbale chachikulu cha valavu chimakankhidwira pamalo otseguka kwathunthu ndi sing'anga yamapaipi: pomwe choponderezera cholowera muchipinda chowongolera pamwamba pa diaphragm (piston) sichingathe kutulutsidwa kumlengalenga kapena kumunsi kwapansi-pansi, Kutsika kwapakati diaphragm (pistoni) ndi yayikulu kuposa kupanikizika komwe kuli pansipa, ndipo sing'anga yomwe ili mupaipi imakanikizira diski yayikulu ya vavu kupita pamalo otsekedwa kwathunthu; Pamene kupanikizika mu chipinda chowongolera pamwamba pa diaphragm (pistoni) kuli pakati pa kukakamiza kwa anthu ndi kutuluka kwa mpweya, diski yaikulu ya valve ili m'malo olamulira, ndipo malo ake olamulira amadalira ntchito yogwirizanitsa ya valve ya singano ndi valavu yoyendetsa yosinthika mu dongosolo la mapaipi ophatikizidwa. Valavu yoyendetsa yosinthika imatha kusintha kutsegulira kwa doko lake la valve malinga ndi kutsika kwapansi ndi kusintha kwake, kuti asinthe kuchuluka kwa kuthamanga kwa chipinda chowongolera pamwamba pa diaphragm (piston) ndikuwongolera kusintha kwa valavu yayikulu. diski.

Valavu yoyendetsera madzi imatha kugawidwa m'mitundu yotsatirayi malinga ndi cholinga.

1) Valavu yoyendetsera madzi. Imawongolera kwambiri kuchuluka kwa madzi mu thanki yamadzi ndi nsanja yamadzi.

2) Valavu yochepetsera kuthamanga. Ndi valavu yomwe imachepetsa kuthamanga kwapamwamba kolowera kumtunda wofunikira ndipo imapangitsa kuti mpweyawo ukhale wolimba podalira mphamvu ya sing'anga yokha.

3) Valavu yoteteza madzi (kupumira / kuthamanga kwa valve). Kuthamanga kwa mapaipi operekera madzi kukadutsa mphamvu yokhazikitsidwa, valavu imatseguka kuti ichepetse kuthamanga kuti iteteze chitetezo cha payipi.

4) Chongani valve. Imayikidwa pamtunda wa mpope wamadzi wamadzimadzi kuti muteteze kubweza kwapakati ndikuchotsa nyundo yamadzi.

5) Valve yamagetsi yamagetsi. Valve ya solenoid imagwiritsidwa ntchito ngati valavu yoyendetsa kuti itsegule patali ndikutseka mapaipi operekera madzi molingana ndi chizindikiro chamagetsi, chomwe chingalowe m'malo mwa chipangizo chachikulu chamagetsi chomwe chimagwiritsidwa ntchito potsegula ndi kutseka valavu yachipata ndi valavu ya butterfly, ndikuzindikira kuwongolera kwakutali. .

6) Valve yowongolera kuyenda. Kuthamanga kwakukulu kumangokhala pamtengo wodziwikiratu ndipo kumtunda kwamtunda kumachepetsedwa mpaka kutsika kwapansi komwe kumafunikira.

7) Valavu yosiyana yodutsa malire. Amagwiritsidwa ntchito pakati pa chitoliro choperekera madzi, chitoliro chobwerera kapena chotolera madzi ndi wogawa madzi a mpweya wozizira kuti athetse kusiyana kwapakati pakati pa chitoliro cha madzi, chitoliro chobwezera kapena chosonkhanitsa madzi ndi wogawa madzi ku mtengo wokhazikitsidwa.

8) Valavu yotseka mwadzidzidzi. Amagwiritsidwa ntchito m'njira yoperekera madzi momwe madzi amoto ndi madzi apakhomo amalumikizidwa molingana, ndipo njira yoperekera madzi imasinthidwa zokha.

9) Mtundu wa diaphragm wotsegula mwachangu valavu yotulutsa matope. Amayikidwa kunja kwa khoma la thanki pansi pa thanki ya sedimentation kuchotsa zinyalala ndi dothi pansi pa thanki.

10) Valavu yotulutsa matope pansi pa diaphragm. Imayikidwa pansi pa thanki ya sedimentation kuchotsa zinyalala ndi dothi pansi pa thanki.

Valve yowongolera madzi ndi valavu yomwe imagwiritsa ntchito kuthamanga kwa madzi mu netiweki ya chitoliro kuwongolera kutsegula, kutseka ndi kutsegula kwa valve. Ndi valavu yodziwikiratu yomwe imapulumutsa anthu ndi mphamvu. Amagwiritsidwa ntchito kwambiri pamakina ophatikizira madzi amadzimadzi monga ulimi wothirira madzi, nyumba zokwera, zoteteza moto, zoperekera madzi mumsewu ndi ngalande, ndi mphamvu zamagetsi. Ntchito zake zimaphatikizira kuwongolera kwamadzi, kuchepetsa kuthamanga, kuchepetsa kuthamanga, kukakamiza, kuwongolera, cheke, kuchotsa nyundo yamadzi, kusinthana ndi ntchito zina. Ikhozanso kusintha mapaipi ophatikizidwa ndi ma valve oyendetsa ndege malinga ndi zosowa zosiyanasiyana kuti akwaniritse ntchito zofunika.
