Kodi ndi chiyanivalavu ya mpira wamtundu woyandama?
Valavu ya mpira woyandama ndi mtundu wa valavu yomwe imagwiritsa ntchito mpira wokhala ndi dzenje pakati ngati gawo lalikulu. Mpirawo umapachikidwa mkati mwa thupi la valavu ndi tsinde, lomwe limalumikizidwa ndi chogwirira kapena lever chomwe chimagwiritsidwa ntchito kutsegula ndi kutseka valavu. Mpirawo ndi womasuka kuyenda kapena "kuyandama" mkati mwa thupi la valavu, ndipo umatsekedwa pamalo pake ndi mipando iwiri kapena zotsekera valavu ikatsekedwa. Vavu ikatsegulidwa, mpirawo umakwezedwa kuchokera pamipando, zomwe zimapangitsa kuti madzi aziyenda kudzera mu valavu. Mavavu a mpira woyandama nthawi zambiri amagwiritsidwa ntchito pa ntchito zopanikizika kwambiri komanso kutentha kwambiri chifukwa amatha kupirira mikhalidwe yosiyanasiyana ndipo ndi osavuta kusamalira.
Kodi kusiyana pakati pa ma trunnion ndi ma valvu oyandama a mpira ndi kotani?
Ma valve a mpira wa trunnion ndi ma valve a mpira woyandama ndi mitundu yonse ya ma valve a mpira omwe amagwiritsidwa ntchito kuwongolera kuyenda kwa madzi kudzera mu payipi. Kusiyana kwakukulu pakati pa awiriwa ndi momwe mpira umathandizira mkati mwa thupi la valve.
Mu valavu ya mpira wa trunnion, mpirawo umathandizidwa ndi ma trunnion awiri, omwe ndi ma projection ang'onoang'ono ozungulira omwe amatuluka pamwamba ndi pansi pa mpirawo. Ma trunnion ali mu ma bearing m'thupi la valavu, zomwe zimathandiza mpirawo kuzungulira bwino valavu ikatsegulidwa kapena kutsekedwa.
Mu valavu yoyandama, mpirawo suthandizidwa ndi ma trunnion. M'malo mwake, umaloledwa "kuyandama" mkati mwa thupi la valavu, motsogozedwa ndi mphete yotsekera. Vavu ikatsegulidwa kapena kutsekedwa, mpirawo umakwera kapena kutsika mkati mwa thupi la valavu, motsogozedwa ndi mphete yotsekera.
Ma valve onse a trunnion ball ndi ma valve oyandama ali ndi ubwino ndi kuipa kwawo. Ma valve a trunnion ball nthawi zambiri amakhala olimba kwambiri ndipo amatha kuthana ndi kupanikizika kwakukulu ndi kutentha, komanso ndi okwera mtengo kwambiri kupanga. Ma valve a rounding ball ndi otsika mtengo ndipo ndi osavuta kuyika, koma sali oyenera kugwiritsidwa ntchito pa kupanikizika kwakukulu kapena kutentha.
Kodi mitundu yosiyanasiyana ya ma valve oyandama ndi iti?
Pali mitundu ingapo ya ma valve oyandama, kuphatikizapo:
1.Valavu yoyandama ya mtundu wa Plunger: Mtundu uwu wa valavu yoyandama umagwiritsa ntchito plunger yomwe imalumikizidwa ku float. Madzi akakwera, float imakwera nayo, zomwe zimapangitsa plunger kukankhira mpando wa valavu, ndikutseka valavu. Madzi akatsika, float imagwa nayo, zomwe zimapangitsa kuti valavu itsegule.
2.Vavu ya Ballcock: Mtundu uwu wa valavu yoyandama umagwiritsidwa ntchito kwambiri m'zimbudzi kuti uzitha kuyendetsa bwino madzi kulowa mu thanki. Umakhala ndi choyandama chomwe chimalumikizidwa ku tsinde la valavu, lomwe limawongolera kuyenda kwa madzi.
3.Valavu yoyandama ya mtundu wa diaphragm: Mtundu uwu wa valavu yoyandama umagwiritsa ntchito diaphragm yosinthasintha yomwe imalumikizidwa ku float. Madzi akakwera, float imakwera nayo, zomwe zimapangitsa kuti diaphragm ikanikizire pa mpando wa valavu, ndikutseka valavu.
4.Valavu yoyandama yamtundu wa paddle: Mtundu uwu wa valavu yoyandama umagwiritsa ntchito paddle yomwe imalumikizidwa ku float. Madzi akakwera, float imakwera nayo, zomwe zimapangitsa kuti paddle ikankhire mpando wa valavu, ndikutseka valavu.
5.Valavu yoyandama yamagetsi: Mtundu uwu wa valavu yoyandama imagwiritsa ntchito maginito amagetsi kuti ilamulire kuyenda kwa madzi. Madzi akakwera, valavuyo imayambitsa maginito amagetsi, omwe nawonso amayambitsa valavu kuti atseke kuyenda kwa madzi.
Kodi cholinga cha valavu yoyandama ndi chiyani?
Cholinga chachikulu cha valavu yoyandama ndikuyendetsa yokha kayendedwe ka madzi kulowa kapena kutuluka mu chidebe kapena thanki. Mavalavu oyandama amagwiritsidwa ntchito m'njira zosiyanasiyana, kuphatikizapo:
1.Matanki a chimbudzi: Ma valve a ballcock amagwiritsidwa ntchito kulamulira kuyenda kwa madzi kulowa mu thanki.
2.Matanki amadzi: Ma valve oyandama amagwiritsidwa ntchito kusunga mulingo wokhazikika wa madzi m'matanki, mwa kulola madzi kulowa pamene mulingo uli wochepa ndikutseka madzi pamene mulingo uli wokwera.
3.Njira zothirira: Ma valve oyandama amagwiritsidwa ntchito polamulira kuyenda kwa madzi kupita kuminda kapena m'minda.
4.Matanki osungiramo mankhwala: Ma valve oyandama amagwiritsidwa ntchito kusunga mulingo winawake wamadzimadzi m'matanki osungiramo mankhwala, kuti atsimikizire kuti mankhwalawo sasungunuka kwambiri kapena kuti asasungunuke kwambiri.
5.Nsanja Zoziziritsira: Ma valve oyandama amagwiritsidwa ntchito kulamulira kuyenda kwa madzi m'nyumba zoziziritsira, kuti madzi azikhalabe okwanira.
Ponseponse, ma valve oyandama amagwiritsidwa ntchito kulamulira kayendedwe ka madzi m'njira zosiyanasiyana pomwe madzi amafunika kukhalabe okwanira nthawi zonse.
NORTECH Engineering Corporation Limitedndi m'modzi mwa opanga ma valve otsogola komanso ogulitsa mafakitale ku China, omwe ali ndi zaka zoposa 20 zokumana nazo muutumiki wa OEM ndi ODM.
