Hlavn\u00fd vinn\u00edk: Zaseknut\u00fd kol\u00edk termostatick\u00e9ho ventilu<\/h3>\n\n\n\n

Ak ste mali radi\u00e1tor dlho vypnut\u00fd (napr\u00edklad po\u010das leta), tesnenie vo vn\u00fatri ventilu sa m\u00f4\u017ee prilepi\u0165 k sedlu. Ke\u010f potom oto\u010d\u00edte hlavicou na maximum, plastov\u00fd mechanizmus vo vn\u00fatri hlavice sa s\u00edce pohne, ale mal\u00fd kovov\u00fd kol\u00edk<\/strong>, ktor\u00fd re\u00e1lne p\u00fa\u0161\u0165a vodu do radi\u00e1tora, zostane \u201evisie\u0165\u201c v zatvorenej polohe.<\/p>\n\n\n\n

\n\n\n\n

Ako to opravi\u0165 (Krok za krokom)<\/h3>\n\n\n\n
    \n
  1. Odmontujte termostatick\u00fa hlavicu:<\/strong> V\u00e4\u010d\u0161inou sta\u010d\u00ed rukou (alebo opatrne klie\u0161\u0165ami) odskrutkova\u0165 kovov\u00fa maticu (prstenec) na mieste, kde sa hlavica sp\u00e1ja s radi\u00e1torom. Nebojte sa, \u017eiadna voda nevyte\u010die \u2013 odkr\u00facate len ovl\u00e1dac\u00ed prvok.<\/li>\n\n\n\n
  2. N\u00e1jdite kovov\u00fd kol\u00edk:<\/strong> Po zlo\u017een\u00ed hlavice uvid\u00edte mal\u00fd strieborn\u00fd hrot (ihlu), ktor\u00fd tr\u010d\u00ed z ventilu. Sk\u00faste ho zatla\u010di\u0165 prstom alebo plochou stranou k\u013e\u00fa\u010da.\n
      \n
    • Spr\u00e1vne spr\u00e1vanie:<\/em> Kol\u00edk by mal pru\u017ei\u0165 \u2013 po zatla\u010den\u00ed by mal s\u00e1m vysko\u010di\u0165 sp\u00e4\u0165.<\/li>\n\n\n\n
    • Chyba:<\/em> Ak je kol\u00edk pevne zatla\u010den\u00fd dnu a ani sa nepohne, na\u0161li ste probl\u00e9m.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
    • Rozh\u00fdbte ho:<\/strong> * Opatrne poklepkajte po boku ventilu (nie priamo po kol\u00edku) kladivkom alebo r\u00fa\u010dkou skrutkova\u010da. Vibr\u00e1cie \u010dasto sta\u010dia na to, aby kol\u00edk vysko\u010dil.\n
        \n
      • Ak to nepom\u00f4\u017ee, chy\u0165te kol\u00edk do kombina\u010diek a jemne<\/strong> s n\u00edm h\u00fdbte smerom k sebe a od seba (ne\u0165ahajte ho von silou, len ho rozh\u00fdbte).<\/li>\n\n\n\n
      • M\u00f4\u017eete pou\u017ei\u0165 trochu spreja typu WD-40 na premazanie.<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n\n\n\n

        Akon\u00e1hle kol\u00edk vysko\u010d\u00ed, mali by ste po\u010du\u0165 \u0161umenie pritekaj\u00facej vody a radi\u00e1tor za\u010dne okam\u017eite hria\u0165. Potom sta\u010d\u00ed nasadi\u0165 hlavicu sp\u00e4\u0165.<\/p>\n\n\n\n

        \n\n\n\n

        In\u00e9 (menej \u010dast\u00e9) pr\u00ed\u010diny:<\/h3>\n\n\n\n
          \n
        • Zatvoren\u00fd spiato\u010dkov\u00fd ventil:<\/strong> Na opa\u010dnej strane radi\u00e1tora (dole) je \u010dasto pod plastovou krytkou druh\u00fd ventil. Ak je zatvoren\u00fd (napr. po rekon\u0161trukcii), voda nem\u00e1 kam odteka\u0165 a radi\u00e1tor zostane studen\u00fd. Skontrolujte ho imbusov\u00fdm k\u013e\u00fa\u010dom.<\/li>\n\n\n\n
        • N\u00edzky tlak v syst\u00e9me:<\/strong> Ak ste vypustili ve\u013ea vzduchu, tlak v kotli mohol klesn\u00fa\u0165 pod kritick\u00fa hranicu (zvy\u010dajne pod 1 bar). Skontrolujte manometer na kotli a v pr\u00edpade potreby dopustite vodu.<\/li>\n\n\n\n
        • Kal a usadeniny:<\/strong> Ak je radi\u00e1tor tepl\u00fd hore, ale \u00faplne studen\u00fd dole, je pravdepodobne zanesen\u00fd kalom. Vtedy odvzdu\u0161nenie nepom\u00f4\u017ee a radi\u00e1tor treba prepl\u00e1chnu\u0165.<\/li>\n<\/ul>\n\n\n\n

          Prevencia do bud\u00facnosti:<\/strong> Po skon\u010den\u00ed vykurovacej sez\u00f3ny (na jar) nechajte v\u0161etky termostatick\u00e9 hlavice otvoren\u00e9 na maximum (stupe\u0148 5). T\u00fdm udr\u017e\u00edte kol\u00edk v uvo\u013enenej polohe a zabr\u00e1nite jeho zaseknutiu po\u010das leta.<\/p>\n\n\n\n

          Chceli by ste vedie\u0165, ako spr\u00e1vne nastavi\u0165 tlak v kotli, ak v\u00e1m po odvzdu\u0161nen\u00ed klesol?<\/p>\n","protected":false},"excerpt":{"rendered":"
