Description

Najdluzszy czas trwania patentu do 26 wrzesnia 1940 t.Glówna skladowa czescia przyrzadu do zbierania! zanieczyszczen z powierzchni wo¬ dy pracujacego kotla stanowi zawór do przedmuchiwania, przedstawiony na rysun¬ ku. Budowa zaworu jest o tyle prosta, ze sama wyjasnia jego dzialanie.Grzybek 1 wraz z trzpieniem 2 stanowi jedna calosc i zakrywa otwór zaworu od strony kotla. Na drugim koncu trzpienia nakrecona jest nasada 3, podtrzymujaca skret sprezyny 7 i przymocowana dodat¬ kowa nakretka 4. Do prowadzenia trzpib- nia znajduja sie skrzydelka 5 z jednego konca, oraz dlalwnilca 6 z drugiego konca. Za¬ wdzieczajac sprezynie 7, która naciska na nasade 3 i na dlawnice 6, zawór jest za^ wsze szczelnie zamkniety. Przy naciiakatalu palca dzwilgfri 9 na trzpien, zawór zostaje otwarty tak dlugo, dopóki dzialaj sie na dzwignie. Po odjeciu reki od dzwigni1 za¬ wór zamyka sie automatycznie i przyciska sie cisnieniem pary. Zawór posiada prze¬ wód odprowaldzajacy 8, skierowany nadól w tym celu, aby woda w nim nie mogla sie zatrzymywac. PLThe longest duration of the patent until September 26, 1940 t. The main component of the collector! contamination from the water surface of the operating boiler is the purge valve shown in the drawing. The construction of the valve is simple enough as it explains its operation. The plug 1 together with the spindle 2 is one whole and covers the valve opening on the boiler side. A cap 3 is screwed on the other end of the spindle, supporting the twist of the spring 7, and an additional nut 4 is attached. For guiding the spindle, there are wings 5 on one end and a tail 6 on the other end. Due to the spring 7 which presses against the head 3 and the glands 6, the valve is always tightly closed. When the finger is pressed against the stem, the valve is opened as long as the levers are acted upon. When you remove your hand from the lever, the valve closes automatically and is pressed with steam pressure. The valve has a drainage line 8 directed above it so that the water in it cannot be stuck.
