Definitions
- the invention relates to a pump with at least one screen valve controlled by the pumped medium, which has a valve disk made of flexible material, which is clamped in a central area and can be moved between an open position and a closed position, in which closed position the valve disk closes at least one valve opening.
- a diaphragm pump is already known from DE 42 00 838 A1, the inlet and outlet valves of which are each designed as a screen valve controlled by the pumped medium.
- Each of these umbrella valves has a valve disk made of flexible material, which is clamped in a central area and is movable between an open position and a closed position. While the valve disc closes at least one valve opening in its closed position, in its open position it rests, at least in regions, on a valve contact surface arranged on its side facing away from the valve opening.
- valve disc Due to the opening and closing movements of the valve disc during pump operation, this valve disc can also strike the surface of the valve contact surface and suddenly displace the air present between the valve disc and valve contact surface, which produces a disturbing noise.
- the pump according to the invention has at least one screen valve, in which projections protrude on the valve disk and / or on the valve contact surface.
- projections protrude on the valve disk and / or on the valve contact surface.
- a preferred embodiment according to the invention provides that the projections provided on the valve disk protrude in a web-like manner over the disk peripheral edge of the valve disk and act on the area of the screen valve which delimits the valve contact surface.
- the valve disk contacts the valve contact surface at most in a wave motion, so that a sudden impact of the valve disk on the valve contact surface and thus a disturbing noise development is avoided.
- valve til disc has several projections that project approximately evenly over the circumference of the disc.
- valve contact surface can intercept the valve disc in its disc shape corresponding to the open position, it is expedient if the valve contact surface is approximately conical.
- a preferred embodiment according to the invention provides that the central region of the valve disk is centered by means of a pin which passes through a central perforation of the valve disk.
- valve disk is connected via at least one of the web-shaped projections to a sealing ring which delimits the valve disk and is tightly clamped between two housing parts.
- This further embodiment according to the invention has the advantage that an unintentional rotation of the valve disk during the opening and closing movements is avoided and corresponding wear on the valve disk is prevented.
- a preferred embodiment according to the invention which does not excessively impede the opening movement of the valve disk, provides that the at least one projection connecting the valve disk and the sealing ring runs at least in sections transversely to the disk radius and in particular in a spiral shape.
- At least one gap serving as a passage opening is provided between the sealing ring and the valve disk.
- FIG. 1 shows a diaphragm pump in a longitudinal section, the inlet and outlet valves of which are designed as screen valves,
- FIG. 2 shows the inlet valve of the diaphragm pump shown in FIG. 1 in its closed position
- FIG. 3 shows the inlet valve from FIG. 2 in its open position
- FIGS. 2 and 3 shows the valve disk of the screen valve shown in FIGS. 2 and 3 in a top view
- FIG. 5 an umbrella valve, the valve disc of which has a modified shape compared to FIGS. 2 and 3, the umbrella valve being shown in its closed position, 6 shows the screen valve from FIG. 5 in its open position, in which the valve disk is at least approximated to a valve contact surface, and
- FIG. 7 shows the valve disk of the screen valve shown in FIGS. 5 and 6 in a plan view.
- FIG. 1 shows a diaphragm pump 1, the inlet valve 2 and the outlet valve 3 of which are each designed as screen valves.
- the shielded valves 2, 3 of the diaphragm pump 1 shown in FIG. 1 have a valve disc 4 controlled by the pumped medium, which is clamped in a central area between a pump head cover 5 and an intermediate cover 6 and centered by means of a pin 7, which has a central perforation 8 in the valve disc 4 interspersed.
- valve disk 4 of the umbrella valves 2, 3 can be moved between a closed and an open position. While the valve disc 4 closes at least one valve opening 9 in its closed position, it moves in the direction of a valve contact surface 10 during its opening movement.
- valve disks 4 of the shielding valves which are shown in greater detail in FIGS. 1 to 4 on the one hand and FIGS. 5 to 7 on the other, are provided, which project in the form of a web above the peripheral edge of the valve disc 4.
- valve disc 4 of this screen valve provided projections 11 act on the area 12 of the screen valve bordering the valve contact surface 10 in such a way that a first contact between the projections 11 and the valve contact surface 10 during the opening movement of the screen valve before the valve disk 4 is applied to the valve Contact surface 10 takes place.
- the air located between valve disk 4 and valve contact surface 10 can thus escape. Since the valve disk 4 thereby makes a wave-like opening movement, clapping of the valve disk on the valve contact surface 10, which is associated with disturbing noises, is avoided.
- valve contact surface 10 is conical and is therefore essentially adapted to the shape of the valve disk 4 in the open position.
- valve disk 4 of the umbrella valves shown there has web-shaped projections 11 which connect the valve disk 4 on the one hand and a sealing ring 13 delimiting the valve disk 4 on the other hand.
- This sealing ring 13 is clamped between the pump head cover 5 and the intermediate cover 6 and seals the screen valve in the intermediate parting plane.
- the molded parts 11 connecting the valve disk 4 and the sealing ring 13 to one another are designed at least in sections transversely to the disk radius and in particular in a spiral shape. These requirements prevent a rotary movement of the valve disk 4 around the pin 7 and thus a corresponding wear and limit - as can be clearly seen in FIG. 3 - the valve opening movement in such a way that a noisy abrupt application of the Valve disc 4 on the valve contact surface 10 is avoided with certainty.
- At least one gap 14 serving as a passage opening is provided between the sealing ring 12 and the valve disk 4.
- a pump equipped with the screen valves shown in FIGS. 1 to 7 is characterized by particularly quiet operation.
