Description
Przedmiotem wynalazku jest zawór odcinajacy, który w przypadku zaniku plomienia uniemozliwia doplyw gazu do urzadzenia grzewczego, znajdujacy zastosowanie zwlaszcza w instalacjach urzadzen grzewczych.The subject of the invention is a shut-off valve which prevents the flow of fire in the event of a flame failure gas for a heating device, which is used especially in the installation of heating devices.
Znane dotychczas zawory pracuja na zasadzie nagrzewania czujników termobimetalowych, które nagrzewajac sie od palnika zwiekszaja swoja dlugosc, naciskajac iglice zaworu co w efekcie umozliwia doplyw gazu do palnika.Previously known valves work by heating thermobimetallic sensors which heating up from the burner, they increase its length by pressing the valve needles, which in turn allows gas to the burner.
Celem wynalazku jest skonstruowanie zaworu, który odcina doplyw gazu do urzadzenia grzewczego w przypadku zaniku plomienia.The object of the invention is to construct a valve which cuts off the flow of gas to the heating device in case of flame failure.
Istote wynalazku stanowi zawór odcinajacy, skladajacy sie z korpusu z gniazdem, w którym znajduje sie grzybek osadzony na trzonie majacym z jednego konca walec oporowy, z drugiego popychacz, oraz z ukladu blokujacego, wspólpracujacego z czujnikiem temperatury i z walcem oporowym. Grzybek wspóldziala ze sprezyna, dociskajaca go do gniazda zaworu.The essence of the invention is a shut-off valve, consisting of a body with a seat in which it is located the mushroom is mounted on a stem with a thrust roller at one end, a pusher at the other, and a system locking, cooperating with a temperature sensor and with a support roller. Mrzybek cooperated with a spring that holds it against the valve seat.
Zaleta zaworu wedlug wynalazku jest to, ze znacznie zwieksza bezpieczenstwo osób obslugujacych urzadzenie grzewcze, jest prosty w budowie i latwy w obsludze.The advantage of the valve according to the invention is that it considerably increases the safety of the operators heating device, it is simple to build and easy to use.
Przedmiot wynalazku jest uwidoczniony w przykladzie wykonania na rysunku, który przedstawia schematycznie zawór w przekroju podluznym.The subject of the invention is illustrated in an exemplary embodiment in the drawing it shows schematically a valve in a longitudinal section.
Zawór odcinajacy zawiera korpus 1 z gniazdem 2', w którym znajduje sie grzybek 3, dociskany do gniazda 2 sprezyna 4, Grzybek 3 osadzony jest na trzonie 5, który na jednym koncu posiada walec oporowy 6, na drugim popychacz 7. Z walcem oporowym 6 wspólpracuje uklad blokujacy, skladajacy sie z zebatki 8, sprezyny 9 i elementu blokujacego 10. Pod walcem oporowym 6 znajduje sie czujnik temperatury 11, z.zaczepem 12, który laczy sie z elementem blokujacym 10 za posrednictwem zebatki 8. Czujnik temperatury 11 jest podtrzymywany sprezyna 13. Ponadto pod czujnikiem temperatury znajduje sie palnik kontrolny 14.The shut-off valve comprises a body 1 with a seat 2 ', in which there is a plug 3, pressed against the seat 2 spring 4, poppet 3 is mounted on a stem 5, which has a support roller 6 at one end, and a support roller 6 at the other pusher 7. The locking system 6 works with the support roller 6, consisting of a gear 8, a spring 9 and a locking element 10. Below the support roller 6 there is a temperature sensor 11, including a catch 12, which it connects to the locking element 10 via a gear 8. The temperature sensor 11 is supported spring 13. There is also a control burner 14 under the temperature sensor.
Zawór odcinajacy dziala w ten sposób, ze w wyniku przylozenia do popychacza 7 sily wiekszej od sily sprezyny 4, trzon 5 z grzybkiem 3 i z walcem oporowym 6 przesuwa sie. Przesuniecie sie walca oporowego 6 powoduje rozlaczenie zaczepu 12 od zebatki 8 i w wyniku zadzialania sprezyny 9 zablokowanie przez element2 94 394 blokujacy 10 ruchu walca oporowego 6 i równoczesnie trzonu 5 i grzybka 3. Czujnik temperatury 11, podgrzewany przez palnik kontrolny 14, wydluza sie, w wyniku czego zaczep 12 przesuwa sie po zebatce 8 ukladu blokujacego, nie powodujac jej ruchu.The shut-off valve works in such a way that by applying to the tappet 7 a force greater than the force the springs 4, the shank 5 with the poppet 3 and the thrust roller 6 move. Thrust roller displacement 6 causes the detachment of the catch 12 from the gear 8 and, due to the activation of the spring 9, it is blocked by the element 2 94 394 blocking the 10 movement of the support roller 6 and simultaneously the shaft 5 and the mushroom 3. Temperature sensor 11, heated by the control burner 14, it lengthens, as a result of which the catch 12 moves over the gear 8 locking system without causing it to move.
W przypadku zaniku plomienia, czujnik temperatury 11 zmniejsza swa dlugosc, a zebatka 8 zostanie wprawiona w ruch przez zaczep 12, przesuwajacy sie w odwrotnym kierunku, co spowoduje odblokowanie walca oporowego 6 wraz z trzonem 5 i grzybkiem 3. Grzybek 3 zostaje docisniety do gniazda 2 sprezyna 4, odcinajac doplyw gazu do urzadzenia.In the event of a flame failure, the temperature sensor 11 reduces its length and the gear 8 remains set in motion by the catch 12, which moves in the opposite direction, which will unlock the roller stop 6 with stem 5 and plug 3. Poppet 3 is pressed against seat 2 by spring 4, cutting off gas supply to the device.
