ntchito

Pafupifupi ntchito zonse zoyendera mapaipi kapena zamadzimadzi, kaya zamafakitale, zamalonda kapena zapakhomo, zimagwiritsidwa ntchitoma valve owunikiraNdi gawo lofunika kwambiri pa moyo wa tsiku ndi tsiku, ngakhale kuti silioneka. Makampani oyeretsa zinyalala, osamalira madzi, osamalira mankhwala, okonza mankhwala, opanga magetsi, osamalira mankhwala, okonza chromatography, ulimi, magetsi ochokera m'madzi, okonza petrochemical ndi okonza chakudya ndi zakumwa amagwiritsa ntchito ma valve owunikira ntchito zawo za tsiku ndi tsiku kuti apewe kubwereranso kwa madzi. Chifukwa amaletsa kulephera kwa zinthu ndipo safuna kuyang'aniridwa panthawi yogwira ntchito, ma valve owunikira si ofunikira kokha, komanso nthawi zambiri amafunidwa ndi lamulo kuti atsimikizire kuti madzi, mpweya, ndi mphamvu zamagetsi zili bwino.

Kunyumba, zimathandiza kuyambitsa ndi kuletsa kuyenda kwa madzi. Amagwiritsidwa ntchito mu zotenthetsera madzi, mapaipi amkati, ma faipu ndi makina otsukira mbale, komanso zida zapamwamba kwambiri monga mapampu oyezera, zosakaniza, zosakaniza ndi zoyezera kuyenda kwa madzi. Ma valve owunikira mafakitale amawunika machitidwe mu nyukiliya, fakitale, fakitale ya mankhwala, makina a hydraulic a ndege (kutentha kwa kugwedezeka ndi zinthu zowononga), makina a mlengalenga ndi magalimoto oyambitsa (kuwongolera momwe zinthu zimayendera, kuwongolera ma propellant, kuwongolera kutalika), ndi machitidwe owongolera kuyenda kwa mpweya (kupewa kusakanikirana kwa mpweya)

Mawonekedwe

Ma valve oyesera akutchuka kwambiri chifukwa cha kapangidwe kake kosavuta komanso kosavuta kugwiritsa ntchito. Njira yake ndi yosavuta. Monga tanenera kale, ntchito ya valve yowunikira imatsimikiziridwa kwathunthu ndi kayendedwe ka njira, zomwe zikutanthauza kuti palibe chowongolera china chofunikira. Nthawi zambiri, valve imagwira ntchito ngati chipangizo chozungulira cholumikizidwa ku mutu wa pampu pa mizere yolowera ndi yotulutsira. Chipangizo chogwirira ntchito chokhala ndi mipata kumapeto onse awiri chimadula chipolopolo ndikugawa chipolopolocho m'zigawo zakumtunda ndi zakumunsi. Mpando wa valve umachokera pakhoma la silinda, koma uli ndi malo otseguka oyenera kuyenda kwa njira.

Mpira, kononi, diski kapena chipangizo china chachikulu chimakhala pampando wa valavu womwe uli pansi pa valavu yowunikira. Kuyenda kochepa kumaletsa chipangizo cholumikizira kuti chisagwedezeke pansi. Madzi akamayenda motsatira njira yodziwikiratu pansi pa kupanikizika kofunikira, pulagi imachotsedwa pampando wa valavu ndipo madzi kapena mpweya umaloledwa kudutsa m'malo omwe amachokera. Pamene kupanikizika kukutsika, pulagi imabwerera pampando kuti isabwererenso.

Makina okoka kapena oyika zitsulo zosapanga dzimbiri nthawi zambiri amachititsa kuti zinthu zibwererenso, koma nthawi zina, kupanikizika kwakukulu kumbali ya valavu kumakhala kokwanira kusuntha zidazo kubwerera pamalo ake oyambirira. Kutseka valavu kumalepheretsa zinthu zapansi kusakanikirana ndi zinthu zakumtunda ngakhale kupanikizika kukukwera. Mapulagi enieni omwe amagwiritsidwa ntchito amasiyana malinga ndi mtundu wa valavu yowunikira yomwe yayikidwa. Monga momwe dzinalo likusonyezera,kugwiritsa ntchito ma valve owunikira mpiramipira. Ma valve oyezera zinthu zokwezera zinthu amagwiritsa ntchito ma cone kapena ma disc omangiriridwa ku ndodo zowongolera kuti atsimikizire kuti abwerera pamalo oyenera pa mpando wa valavu. Ma valve ozungulira ndi ophimba zinthu amagwiritsa ntchito diski imodzi kapena zingapo kuti atseke mpata pa mpando.

Ubwino wa valavu yoyezera

Ma valve oyesera ali ndi ubwino wambiriChoyamba, amatha kuwongolera kuyenda kwa psi m'magawo osiyanasiyana amafakitale. Ndipotu, amatha kugwira ntchito ndi mphamvu ya psi yokwanira kuzimitsa moto, ndipo mphamvu ya psi imayendetsedwa mokwanira kuti igwire ntchito mu silinda ya scuba. Ubwino wina wa ma valve oyesera ndi wakuti amaletsa kuipitsidwa kwa madzi, kuphatikizapo madzi abwino.
