1. Maonekedwe
1.1.Vavu yoyandama ya mpira ndi valavu ya trunnion yokwera ndi yosavuta kusiyanitsa mawonekedwe.Ngati thupi la valavu lili ndi shaft yotsika yokhazikika, iyenera kukhala valavu yokwera mpira.(Mutha kunena za mawonekedwe a valve ya mpira kuchokera ku RXVAL Valves).
1.2.Ngati pali valavu yamafuta pa valavu ya mpira, ndiye kuti ndi valavu ya mpira.
Koma zosinthazo sizowona.Sikoyenera kukhala ndi valavu ya mpira yoyandama popanda valavu yamafuta, chifukwa kakulidwe kakang'ono monga 1″ 300LB trunnion wokwera valavu ya mpira nthawi zambiri alibe valavu yamafuta.(Mutha kunena za mawonekedwe a valavu ya mpira ya RXVAL)
2. Mfundo Yogwira Ntchito
2.1 Mpira wa valavu ya mpira woyandama uli ndi tsinde lapamwamba lokha, ndipo mpirawo ulibe tsinde lothandizira.Pansi pa kusiyana kwa kupanikizika, mpirawo ukhoza kusamutsidwa pang'ono, choncho umatchedwa valavu ya mpira yoyandama.
Palinso shaft yokhazikika pansi pa trunnion wokwera valavu ya mpira, yomwe imakonza malo a mpirawo, choncho sungathe kuchotsedwa, choncho imatchedwa trunnion wokwera mpira valve.
2.2 Mpira wa valve yoyandama umasunthidwa chifukwa cha kukakamizidwa kwa sing'anga, ndipo umamangirizidwa mwamphamvu kumpando wa valve kuti ukwaniritse kusindikiza.M'pofunika kuganizira ngati zinthu za mpando akhoza kupirira ntchito mavuto.
Mpira wa trunnion wokwera valavu ya mpira umakhazikika, ndipo mpando umasunthidwa ndi kukakamizidwa kwa sing'anga, ndipo umamangirizidwa mwamphamvu ku mpira kuti ukwaniritse kusindikiza.
3. Ntchito ndi Kugwiritsa Ntchito
3.1 Valavu yoyandama ya mpira ndi yoyenera kupanikizika kwapakatikati ndi kochepa, ndipo m'mimba mwake ndi yaying'ono;valavu ya trunnion yokwera imatha kupirira mpaka 2500LB, ndipo kukula kwake kumatha kufika mainchesi 60.Mwachitsanzo, valavu yayikulu kwambiri komanso yothamanga kwambiri ya RXVAL ndi trunnion wokwera valavu ya mpira.
3.2 valavu ya mpira wa Trunnion imatha kuzindikira ntchito ya Magazi awiri ndi Magazi, pomwe valve yoyandama imakhala yosindikizira njira imodzi.Valve ya mpira wokhala ndi trunnion imatha kutsekereza sing'anga kumtunda ndi kumunsi kumapeto nthawi yomweyo.Pamene kupanikizika kwapakati pa thupi la valve kuli kwakukulu kuposa mphamvu yomangirira ya kasupe wa mpando wa valve, mpando wa valve udzagwedezeka kuti utulutse kupanikizika muzitsulo kuti zitsimikizire chitetezo.
3.3 Mavavu a mpira okhala ndi Trunnion nthawi zambiri amakhala ndi moyo wautali kuposa ma valve oyandama.Malinga ndi ndemanga ya ogwiritsa ntchito, valavu ya mpira yokhazikika ya RXVAL yakhala ikugwiritsidwa ntchito kwa zaka 10 popanda vuto lililonse.
3.4 Makokedwe a valavu ya trunnion yokwera mpira ndi yaying'ono kuposa ya valve yoyandama, motero ntchitoyo imapulumutsa ntchito.
3.5 Vavu ya mpira wokwera pamwamba pa mainchesi 4 imakhala ndi valavu yamafuta, koma valavu ya mpira woyandama siyitero.
3.6 Kusindikiza kwa valavu ya trunnion yokwera mpira ndi yodalirika kwambiri: mphete yosindikizira ya PTFE imodzi imayikidwa mu mpando wa valve yachitsulo chosapanga dzimbiri, ndipo mapeto a mchira wa mpando wa valve wachitsulo amaperekedwa ndi kasupe kuti atsimikizire mphamvu yokwanira yolimba. wa mphete yosindikizira.Valve ikupitiriza kuonetsetsa kuti ntchito yabwino yosindikiza ikugwira ntchito pansi pa kasupe.
3.7 Valavu ya mpira yokhala ndi trunnion imakhala ndi valavu yamafuta, yomwe imakhala ndi ntchito yobaya mafuta osindikizira pamene valavu yatuluka.
3.8 RXVAL chikumbutso chochezeka, Ngati valavu ya mpira yofanana ndi yomweyi, valavu ya mpira yomwe imakhala ndi trunnion nthawi zambiri imakhala yokwera mtengo kuposa valavu yoyandama ya mpira.
