Definitions
- the invention relates to a pump with tongue valves controlled by the pumped medium and accommodated in the pump head, which in the closed position rest against a valve sealing surface of the pump head and, in the open position, dodge in a recess of the valve head for the valve opening movement, the valves having one or more valve disks, in which valve tongues are delimited by, in particular, part-ring-shaped recesses, which are connected in an articulated manner to the rest of the valve disk via a web, and the valve disk is clamped between pump head parts in the area surrounding a valve.
- valves In order to achieve good self-priming and good volumetric efficiency in such liquid and gas pumps designed as diaphragm pumps, it is important that the valves perform their opening and closing movements as synchronously or congruently as possible with the diaphragm lifting and lowering movements and thus achieve the longest possible opening and closing times .
- the valve plate located therebetween which is made of rubber or a rubber-like material, is pressurized and that this leads to material displacement. Due to the proximity of the clamping point to the valve tongue, the displaced material also influences the valve tongue, since transmission via the bridge-like connecting web is possible.
- This material displacement can lead to an undesirable deformation of the web and also the valve tongue.
- Such a deformation of the web or the valve tongue results but an impairment in the sense that the opening and closing movement or the opening and closing speed is hindered. This results in a deterioration in the valve response time.
- the object of the present invention is to provide a pump with tongue valves of the type mentioned at the beginning, the reaction times of which are improved, so that the pump can also be used particularly well for high working speeds.
- the self-priming behavior and the volumetric efficiency should also be improved.
- the invention proposes in particular that at least one recess or interruption of the valve disk is provided in a connection area between the valve tongue, web and external clamping, adjacent to the web, facing away from the valve tongue. Material displacements originating from the clamping area no longer reach through the recess provided to the web and via this into the area of the valve tongue.
- the interruption or recess practically creates a buffer space in which material displacements can evade without having any further effect on the other side.
- the distance between the outer clamping and the valve tongue or the web could also be increased in order to reduce the effects of the material displacement that occurs, but this is practically impossible because of the limited space in the pump head.
- the effects of material displacement can be kept practically completely away from the valve tongue, although this is also possible under the given, restricted space.
- the width of the recess expediently corresponds to Direction of the connecting line between the valve tongue, the web and the outer clamping at least the measure of a material displacement resulting from the external clamping. This creates enough free space to keep material displacements or material displacements in the direction of the web and the valve tongue from the clamping of the valve disk.
- the recess in the valve disc which is in the extension of the valve tongue and web, preferably extends laterally and preferably symmetrically beyond the direct projection extension of the web.
- 1 is a longitudinal sectional view of a diaphragm pump with tongue valves
- Fig. 2 is a detailed view in the region of a valve in longitudinal section
- Fig. 3 is a partial supervision of a valve plate.
- a diaphragm pump 1 shown in FIG. 1 A diaphragm pump 1 shown in FIG.
- crankcase 2 on a crank mechanism 3, which is connected to a connecting rod
- the pump chamber 6 delimited on one side by the membrane 5 is on the opposite side. overlying side bounded by an intermediate plate 8 belonging to the pump head 7.
- a head plate 9 connects to the intermediate plate 8.
- An inlet valve 10 and an outlet valve 11 are located in the pump head 7. Both valves are designed as tongue valves which each rest on valve sealing surfaces 12 in the closed position. Opposite these valve sealing surfaces 12 there are recesses 13, into which the valve tongues 14 belonging to the valves can escape during a valve opening movement.
- valves have a preferably common valve disk
- valve disc 15 is clamped between the head plate 9 and the intermediate plate 8 of the pump head 7.
- the clamping points each delimit the area of the inlet valve 10 and the outlet valve 11 and also seal these areas from one another.
- FIGS. 2 and 3 there is a web 17 between the opposite ends of the partially annular recess 16 surrounding the valve tongues 14, on which the valve tongue 14 is held movably and is connected to the remaining valve disk 15.
- the valve disc 15 is clamped in the area delimited in FIG. 3 between the top plate 9 and the intermediate plate 8 (see also FIG. 2). This clamping inevitably displaces the material of the elastic valve disk 15 located in between. If the effects of such a material displacement reach the area of the bridge-like web 17 or also the area of the valve tongue 14, a corresponding deformation can take place.
- Such deformation can have the consequence that the bending stability changed in an uncontrolled manner in the region of the valve tongue and / or of the web 17, so that the intended sequence of movements when opening and closing the valve tongue 14 is no longer guaranteed to the desired extent.
- a recess 19 is provided in the valve disc 15 between the clamping area 18 adjacent to the web 17 and the web 17. This recess 19 forms in the connection area between the web 17 and the clamping area
- the recess 19 is designed as a slit in the form of a segment of a circle, which extends on both sides slightly beyond the area of the web width.
- the length 1 of this recess slot is dimensioned such that the deformations of the valve disk 15 resulting from the clamping area 18 cannot propagate to the web or to the valve tongue 14.
- the same also applies to the position of the recess 19 relative to the web 17, in particular also with regard to the distance to the web 17 and also with respect to the slot width b.
- the length of the recess slot 19 is preferably approximately five times the web width s.
- the distance of the recess 19 from the web 17 corresponds approximately to the web width.
- the circular section-shaped design of the slot-shaped recess 19 shown is particularly favorable given the available space.
- Figure 2 shows clearly that in the area of the recess
