DE452615C - Waste flushing device with a valve chamber connected to the bottom of the air chamber - Google Patents

Description

The invention relates to a waste rinsing device with a bottom connected to the air chamber Valve chamber.

The novelty consists in the special design of the one arranged in the valve chamber Drain valve. This is designed so that it is so long after its opening remains locked in this position until all the water has drained from the air tank.

In the drawing, an embodiment of the new flushing device is shown.

Fig. Ι shows a vertical .Schnitt through an air chamber (cast iron) with the valve chamber connected below. The drain valve is shown here in the open position.

Fig. 2 illustrates a vertical section through the one made from stamped sheet metal Air chamber. The drain valve of the chamber is shown here in the closed position ao.

Fig. 3 shows in cross section the closure, guide and base plate with the valve.

Fig. 4 shows the locking flap of the drain valve in side view and top view.

The air chamber α is shown in Fig. 1 made of cast iron with cast-on fastening ears b and in Fig. 2 made of stamped sheet metal.

In the ceiling of the water tank a. an air valve 0 is installed, which closes in a known manner at a certain water level, so that the water tank forms a closed boiler. The valve chamber e for the drain valve connects to the bottom.

The valve chamber e is screwed directly into the air chamber α in a sealing manner. The valve chamber consists of a cylindrical part with a lateral drain opening e ¹ for connection to the water drain pipe through which the water is directed into the basin. The upper part of the cylindrical part of the valve chamber e is provided with a conically ground valve seat for the shut-off valve ν . The head of the shut-off valve is expediently rounded at the top, while its side edges drop conically in accordance with the inclination of the valve seat. The shut-off valve ν carries a central-axial valve stem v ^% , which is offset over part of its length at v ^2. On the valve stem v ¹ sits a guide sleeve f which, in its lower part, has an outwardly protruding edge flange Z ¹ . The valve chamber e is closed off by a base plate g which is fastened to the valve chamber e in any desired manner. This base plate g merges into an inwardly protruding cylindrical socket h , in which the stem v ^{1 of} the valve υ is inserted, while the socket in turn pushes into the annular gap between the offset valve stem v ^x and the guide sleeve / itself, in this way a making good watertight routing of valve ν. Two bearing lugs i are attached under the base plate g (Fig. 3), in which a weight-loaded cam-type lever k is ^{mounted on a pivot pin i 1,} which oscillates on the valve stem v ¹ protruding through the base plate g and the valve ν can lift. As can be seen from Fig. ¹ , the lever k has an upwardly projecting nose k 1 for this purpose. The lever k is held in the rest position by the counterweight. In order to ensure reliable emptying and to prevent the valve ν from falling back into its closed position during water drainage, a locking device is provided which consists of a double-armed flap I rotatably mounted on the inside of the base plate g , the two surfaces of which form an obtuse angle form. The cutout P present in the forked arm I ¹ receives the connector h of the base plate g , the forked arm V- engaging under the edge flange f ^{1 of} the sleeve f . Under the load of the shut-off valve ν , the double-armed flap I is usually pressed down on the base plate b , while the full plate part lies in front of the discharge opening e ^1. The double-armed flap I is rotatably mounted between bearing lugs g ¹ (Fig. 3) on the base plate g. For the water inlet, a connecting piece is provided laterally q from the valve through which an inlet tube extends into the container ¹ q. The operation of the waste rinsing device is as follows: After the air chamber α has been filled in a known manner, it is to be emptied, for which purpose the lever k , which is similar to a hub, is pulled. This lifts the valve ν η ° through its nose k ¹ , and the water under pressure in the air tank α initially plunges into the valve chamber e, where it hits the relieved full-walled part of the flap I and the flap L folds over in the outlet opening e and releases them. The forked arm of the flap I lies there ¹ : ei under the flange f ^{1 of} the valve sleeve f, so that when the lever k is released, the valve ν can no longer fall down. The air inlets of the air valve 0 of the "air chamber a are α with decreasing water level in the surge tank released so that the water nachströmt with great force and the air chamber α can empty completely. There is therefore achieved a strong flush. Once the water from the surge tank is a completely drained and the flap I relieved is exposed, is ν under the dead weight of the valve and f its sleeve and the ν of the valve directed beam of α in the air chamber built-tube of the pressurized water conduit, the valve subside and turn the flap I so that it lies in front of the outflow opening e ¹ , whereupon the air vessel α is filled again in a manner known per se.
