ntchito

Pafupifupi mapaipi onse kapena zoyendera zamadzimadzi, kaya zamakampani, zamalonda kapena zapakhomo, zimagwiritsidwa ntchitofufuzani ma valve. Ndi gawo lofunika kwambiri pa moyo watsiku ndi tsiku, ngakhale kuti ndi zosaoneka. Madzi onyansa, madzi, chithandizo chamankhwala, kukonza mankhwala, mphamvu zamagetsi, mankhwala, chromatography, ulimi, hydropower, petrochemical ndi mafakitale opanga zakudya ndi zakumwa amagwiritsa ntchito ma valve owunika pa ntchito zawo za tsiku ndi tsiku kuti ateteze bwino kubwerera. Chifukwa chakuti amalepheretsa kulephera kwa mankhwala ndipo safuna kuyang'aniridwa panthawi yogwira ntchito, ma valve owunika samangofunika, koma kawirikawiri amafunidwa ndi lamulo kuti atsimikizire chitetezo cha madzi, gasi, ndi ntchito zokakamiza.

Kunyumba, amathandizira kuyambitsa ndikuletsa kutuluka kwamadzimadzi. Amagwiritsidwa ntchito muzotenthetsera madzi, mapaipi amkati, mipope ndi zotsukira mbale, komanso zida zapamwamba kwambiri monga mapampu a metering, zosakaniza, zosakaniza ndi ma flow meters. Ma valve oyang'anira mafakitale amawunika machitidwe a nyukiliya, fakitale, malo opangira mankhwala, makina opangira ma hydraulic a ndege (kutentha kwa kugwedezeka ndi zida zowononga), ndege zam'mlengalenga ndi makina oyambitsa magalimoto (kuwongolera, kuwongolera, kuwongolera, kuwongolera), ndi machitidwe owongolera mpweya (kupewa kusakanikirana kwa gasi). )

Mawonekedwe

Ma valve owunika akukhala otchuka kwambiri chifukwa cha kapangidwe kake kosavuta komanso kosavuta kugwiritsa ntchito. Limagwirira ndi losavuta. Monga tanenera kale, ntchito ya valve yowunikira imatsimikiziridwa kwathunthu ndi kayendedwe kake, zomwe zikutanthauza kuti palibe chowonjezera chowonjezera chomwe chikufunika. Nthawi zambiri, valavu imagwira ntchito ngati chipangizo cha cylindrical cholumikizidwa ndi mutu wa pampu pamizere yolowera ndi potuluka. Chipangizo chogwirira ntchito chokhala ndi zitseko kumbali zonse ziwiri chimadutsa chipolopolocho ndikugawaniza chipolopolocho kumtunda ndi kumunsi kwa mtsinje. Mpando wa valavu umachokera ku khoma la silinda, koma uli ndi kutsegula koyenera kuyenda.

Mpira, cone, disc kapena chipangizo china chokulirapo chimakhazikika pampando wa valavu kumbali yakumunsi ya valavu. Kuyenda kochepa kumalepheretsa chipangizo cholumikizira kuti chisagwetsedwe pansi. Pamene madzimadzi akuyenda mu njira yokonzedweratu pansi pa kukanikiza kofunikira, pulagi imachotsedwa pampando wa valve ndipo madzi kapena mpweya amaloledwa kudutsa kusiyana kwake. Pamene kuthamanga kumatsika, pulagi imabwerera kumpando kuti iteteze kubwerera.

Mphamvu yokoka kapena zitsulo zosapanga dzimbiri zonyamula kasupe nthawi zambiri zimakhala ndi udindo pa kayendetsedwe kameneka kameneka, koma nthawi zina, kupanikizika kowonjezereka kumbali ya pansi pa valve ndikokwanira kusuntha zipangizo kubwerera kumalo ake oyambirira. Kutsekedwa kwa valavu kumalepheretsa zinthu zapansi kuti zisagwirizane ndi zinthu zakumtunda ngakhale pamene kupanikizika kumawonjezeka. Mapulagi enieni omwe amagwiritsidwa ntchito amasiyana malinga ndi mtundu wa valve yoyika. Monga dzina limatanthawuzira,kugwiritsa ntchito ma valve a mpiramipira. Ma valve okweza amagwiritsira ntchito ma cones kapena ma disc omwe amamangiriridwa ku ndodo zowongolera kuti atsimikizire kuti abwerera pamalo oyenera pampando wa valve. Ma valve opindika ndi opindika amagwiritsira ntchito diski imodzi kapena zingapo kuti atseke kusiyana pampando.

Ubwino wa cheki valve

Ma valve owunika ali ndi zabwino zambiri. Choyamba, amatha kuwongolera kuthamanga kwa psi m'magawo osiyanasiyana amakampani. Ndipotu, amatha kugwira ntchito pamtunda wokwanira wa psi kuti azimitsa moto, ndipo kuthamanga kwa psi kumayendetsedwa mokwanira kuti agwire ntchito mu scuba cylinder. Ubwino wina wa ma cheke ma valve ndikuti amalepheretsa kuipitsidwa kwamadzimadzi, kuphatikiza madzi abwino.
