Mwatsatanetsatane njira yoyendetsera bwino mavavu I

Valavu ndi chipangizo chomwe chimagwiritsidwa ntchito poyang'anira mayendedwe, kupanikizika ndi kutuluka kwa madzi mumadzimadzi, zomwe zimatha kupanga sing'anga (madzi, mpweya, ufa) muzitsulo ndi zida kuyenda kapena kuyimitsa ndi kuyendetsa kayendedwe kake. Valavu ndi gawo lofunikira lowongolera mumayendedwe amadzimadzi.

Kukonzekera musanayambe ntchito

Musanagwiritse ntchito valavu, werengani malangizo ogwiritsira ntchito mosamala. Musanagwiritse ntchito, onetsetsani kuti mukudziwa momwe gasi amayendera, ndipo samalani kuti muwone zizindikiro zotsegula ndi zotseka za valve. Yang'anani maonekedwe a valve kuti muwone ngati yanyowa. Ngati chanyowa, chiwume; ngati zipezeka kuti pali zovuta zina, zithetseni munthawi yake ndipo musagwire ntchito ndi zolakwika. Ngati valavu yamagetsi yatha miyezi yoposa 3, yang'anani clutch musanayambe. Pambuyo potsimikizira kuti chogwiriracho chili pamanja, yang'anani kutsekereza, chiwongolero ndi magetsi agalimoto.

Kuchita bwino kwa valve yamanja

Valve yamanja ndiye valve yogwiritsidwa ntchito kwambiri. Chingwe chake cham'manja kapena chogwirira chimapangidwa molingana ndi anthu wamba, poganizira mphamvu ya kusindikiza pamwamba ndi mphamvu yotseka yofunikira. Choncho, sikuloledwa kusuntha ndi lever yaitali kapena wrench yaitali. Anthu ena amazolowera kugwiritsa ntchito wrench, choncho ayenera kusamala kwambiri. Potsegula valavu, ayenera kugwiritsa ntchito mphamvu zokhazikika kuti apewe mphamvu zambiri, zomwe zidzayambitsa kutsegula ndi kutseka kwa valve. Mphamvuyo iyenera kukhala yokhazikika osati kukhudzidwa. Magawo ena a ma valve othamanga kwambiri okhala ndi kutsegulira ndi kutseka kwamphamvu amalingalira mphamvu yamphamvu ndi ma valve ambiri sangakhale ofanana.

Vavu ikatsegulidwa kwathunthu, tembenuzirani gudumu lamanja pang'ono, kuti ulusiwo ukhale wolimba kuti zisawonongeke komanso kuwonongeka. Pa mavavu a tsinde otseguka, kumbukirani momwe tsinde la valavu lilili lotseguka komanso lotsekedwa bwino kuti musamenye pakati pomwe pali tsinde lotseguka. Ndikwabwino kuyang'ana ngati ili yabwinobwino ikatsekedwa kwathunthu. Ngati ofesi ya valavu ikugwa, kapena valavu yaikulu imayikidwa pakati pa zisindikizo zapakati pa valve, malo a valve amatha kusintha pamene valavu yatsekedwa kwathunthu. Kuwonongeka kwa ma valve osindikiza pamwamba kapena ma valve handwheel.

Vavu yotsegulira chizindikiro: pamene poyambira pamwamba pa ndodo ya valavu ya valavu ya mpira, valavu ya butterfly ndi valavu ya pulagi ikufanana ndi njira, zimasonyeza kuti valavu ili pamalo otseguka; pamene ndodo ya valve imazungulira 90 kumanzere kapena kumanja. Pamene, poyambira ndi perpendicular kwa njira, kusonyeza kuti valavu ali pa malo otsekedwa kwathunthu. Mavavu ena a mpira, mavavu agulugufe ndi mapulagi mavavu amatsegula pamene wrench ikufanana ndi njira, ndi kutseka pamene wrench yaima. Ma valve a njira zitatu ndi zinayi adzagwiritsidwa ntchito molingana ndi zizindikiro za kutsegula, kutseka ndi kubwerera. Chotsani chogwirizira chosunthika mukatha ntchito.
