Low-noise throttle valve

The present invention is therefore based on the object

The present invention relates to a low noise
Throttle valve according to the preamble of the main claim.

Such throttle valves are found in a variety of \ household appliances, such as water heaters for utility ^; water. In some cases they are even required to be used in the
Service trap to disconnect the device from the water supply. When loading 'drive of the downstream domestic appliance but flows through these valves ^f continuously from the water here is often complained that these valves to strong Fließgeräu- |

see generate that via the aqueduct respectively |

Walls and air are carried over and disturb roommates. |

To propose a low-noise throttle valve with which you can not only shut off the water network, but also one can achieve more or less throttled water throughput, and in which the generation of noise is minimized both in the maximum opening area and up to the almost closed state is.

The solution to this problem succeeds with the characterizing features of the main claim =

The resulting technical port step is essentially in the combination of good adjustability of the water throughput with the lowest possible sound radiation to see.

Further refinements and particularly advantageous developments the innovation emerge from the subclaims and the following description, which is based on the figure Embodiment of the innovation explained in more detail.

The figure shows a cross-sectional view of a water angle valve .

A corner valve in the course of a water supply line to an electrical one The heated water heater has a valve housing 1 with an inlet-side connection 2 and an outlet-side Connection 3, through which process water flows in the direction of arrow 4. Between the inlet and outlet nozzles

2 or 3, a constriction 5 is provided which forms the narrowest point in the area of the housing 1 from sprayed or beaten metal.

In a further connection piece 6, a stuffing box 7 for receiving an actuator 8 is provided, which of a Handle 9 can be actuated.

A one-piece plastic injection-molded part 11 is located in the interior 10 in the area of the connecting piece 2 and the connecting piece 6 pressed in, which in turn has a constriction 12 in the area

of the outer jacket 13. In the constriction 12 of the outside

jacket 13 engages the constriction 5 of the housing 1 = thus the insert 11 can be snapped into place behind the constriction 5 are held. In the area of the inlet connection piece 2 is on part 11 an extension 14 in the form of a

Cone or a hemisphere provided, the slots 15 on- ϊ

shows. The axis 16 of the cone is aligned when trained as

Angle valve with the axis of the connecting piece 2. In the area of the constriction 12, there are no slots in the plastic injection-molded part. In the downstream space 17 expands the plastic injection molded part to a hollow cylinder 18, the same- '. if it has slots 19. An extension is thus formed here which is open at its downstream end. here the individual slots reach up to an annular collar which is formed by the end face of the stuffing box 7 on the water side is, while the slots end in the area of the extension 14 or the hemisphere 21, the webs of the cone

are therefore connected to each other here.

The plastic insert 11 delimits an interior 22 which is connected via the slots 15 of the cone 14 to the interior 10 of the inlet connection 2, which on the other hand with the Space 17 is connected via the slots of the hollow cylinder 18 and its interior.

In the interior 23 of the hollow cylinder, a valve body 24 is movable in the direction of the axis 16, to which it is also aligned, it is articulated by the actuator 8. When the handle 9 is actuated, the valve body 24 is moved in the direction of the axis 16 .

The outlet 3 is through the slots 19 with the interior 22 connected inside the hollow cylinder 20. The puncture of the described low-noise throttle valve is as follows :

In the closed state, the valve seat 24 lies with its closing surface 25 on valve seat 26 and seals.

By operating the handle 9, the valve body 24 is raised via the actuator 8, so that in the area between Surface 25 and valve seat 26 creates an annular gap. Thus, water can in the direction of arrow 4 from the connection piece 2 pass through the port set 14 via the multiplicity of hydraulically parallel-connected slots 15 and reach its interior 22. After passing through the valve seat 26, the water
