Waste flush valve Patented in the German Empire on February 21, 1926

Flushing valves with a settling effect, in which one pierced in its direction of movement and slider under the influence of the flow within the Slide chamber is reversed between stops are known and it work such settling as long as the influence of the flow on the slide persist remains, d. H. is not interrupted, i.e. locked.

With these valves, the flow can be interrupted by the slide itself take place, in which case the slide must be adjusted again by hand, should activate the valve again, or the valve will work continuously for as long the flow is not shut off. The subject of the invention is an improvement of the valves described above

ao by the fact that the slide is only positively reversed, that is, moves back and forth is if the flow is interrupted by an auxiliary double slide or time is passed, the auxiliary slide automatically returning to its starting position, which of the ready position of the valve, so the filling position of the drawn Device, corresponds. The movement of the auxiliary double slide can be done by hand or done mechanically, insofar as the valve is opened during the return movement can also be done positively in the initial position.

The valve can be used for all liquids and gases that are under pressure, and it can be used for automatic filling of measured amounts of filler, as Flushing device, as shown in the drawings, o.

In the drawing, the invention is shown, for example, on a flushing valve for drain flushing devices shown and described.

Fig. Ι shows such a valve in the closed position, that is, in the ready position for flushing. The filled container, which acts as an air vessel, is arranged vertically above the valve and connected to the inflow line g through the slide chamber d . For the play of the slide b, the slide chamber is provided with two stops e and a lateral ring opening h arranged between these stops, which is combined into an outflow ρ by the slide chamber casing. The slide b has a through hole c and at one end a check valve, represented by the chamber ν and the ball / fitting therein. The inflow line g is also secured against backflow from the container or from the slide chamber by a check valve. In the lower part of the slide chamber below the slide and its lower stop e is an auxiliary double slide /, which can also be designed as a three-way valve, installed so that it is inevitably at the same time when he is by hand through the

Claims (3)

Knee lever m is moved inwards, the slide chamber closes off against the inflow g and opens against the outflow ^ ¹ at ο. The return movement of the auxiliary double slide i takes place in a non-positive manner through the operating pressure from the supply line g ″ and can be supported by spring pressure. Fig. 2 shows the valve in the SteEung during flushing, ie during the emptying of the container α through the ring opening h to p. The mode of operation of the valve during this changeover or back to the initial position is as follows: If the auxiliary double slide is pressed inwards when the valve is in the position shown in Fig. I, the slide chamber d is opened at ο and at the same time the supply line g is shut off at k. As a result of the opening of the 2Q slide chamber at ο , the chamber below slide b is depressurized, and the latter is reversed into the position according to Fig. 2 by the operating pressure held by the check valve / in the container, and the container contents are emptied from a with expansion of the in the same enclosed compressed air through h to ρ and thus to the drainage bowl and flushes such. If the hand lever m released so the Help s double-shifting he / moved back to its initial position according to Fig. 1, characterized in that the operating pressure from the feed line g · the same as long forward sliding is applied, until the opening released k through which the direct connection between the valve chamber and the supply line is restored. With this flow from g to α, the slide b is moved in the direction of flow towards the upper An-40. blow »? moves so that the through-hole opposes the throughflow due to the cross-sectional constriction a corresponding resistance which is sufficient for this movement and thus also to overcome the friction of the slide on the walls of the slide chamber; accordingly, the through-hole in the slide δ is to be dimensioned in relation to the clear cross-section of the inflow line g. Fig. 3 "shows an otherwise identical design as in Fig. 1, but with a longer auxiliary slide z, which means that during the return movement the same a certain larger time is gained, which can be used for the flushing time is. Fig. 4 shows an embodiment, otherwise like Fig. I, but with a diversion t between the supply line g and the container a. The auxiliary slide is arranged in this embodiment so that he also the. Diversion t opens or closes, namely the same inevitably opens the slide chamber at dop and the diversion at gkta to the container, and it closes the slide chamber dkg at the same time. When the auxiliary double slide is moved back to its initial position as shown in Fig. 4, the flow is influenced in the opposite direction. The purpose of this design is to increase the amount of flushing water as desired, i.e. as long as the auxiliary double slide is held inward by pressing the button q , not only the amount of water contained in the container is expelled at ρ , but also that flowing from the supply line g at all flows Amount of water with through ρ . Ρλ τ ε ν τ λ χ propositions: ι. The outlet flush valve closes automatically due to the pressure of the inflow line and has a piston that can move freely in the lower cylindrical nozzle of the air chamber, characterized in that an auxiliary double slide (1) is arranged in the slide chamber below the slide (b) , which at the same time inevitably connects the supply line (0 ·) To the slide chamber (at K) and the slide chamber (d at o) opens, whereby a non-return valve (V) arranged on the slide (b) blocks the return flow from the container (a) through the slide. 2. Flush valve according to claim 1, characterized in that the supply line (g) through a diversion (V) alternately through the auxiliary slide (/) with the container (a) or the slide chamber (d) . connected or lockable against such. 3. Flush valve according to claim 1 and 2, characterized in that the slide (b) is inflated from the inside out by the operating pressure during the filling position (Fig. 1). 1 sheet of drawings
