Low-noise water outlet fitting

The noises made by water drain fittings are one of the most common interfering with noise sources within a * house, e.g. a house, hotel or hospital. Various measures have become known, this gate everything reduce annoying noise at night. So you have a flow resistance, see B. in the form of tou screen plates, wire mesh, LArch or from spirally wound sheet metal strips arranged at the inlet or outlet of a valve. Solo resistances cause a reduction in the amount of water flowing through per unit of time and thus also a reduction in noise · However, this is only suitable to a limited extent «If you just want the familiar one If you reach a low noise level, the faucet lets through little water so that you can still, see B. for the enema of a bath, be useful ssu.

Other measures that are expedient per se have also become known, which, however, lead to a substantial reduction in noise of the fittings did not lead. (See K. Gusele and CA. Toigtsberger "Fundamentals of Noise Reduction at Vaeeerauslauf & ma doors ", Ges. Ing. 1970, Issue 4, pp. 108 - 117)

The invention is based on the knowledge that there are always several sources of noise in a valve. It after that, nothing helps, for example only running the actual tent quietly, if the inlet is not on the same side ma Tentil and the axial run out of the valve are low-noise are executed. That is why there are always

becomes because "Qeräusoh, since * from Ventileita comes up," a ao less. The larger the diameter of the veatil sltftos 1st. Therefore one should have the diameter as large as Böglioa aMeaeB. For aesthetic and economic reasons, the outer shape of the fitting is given.

Haotx of the invention is therefore seen that your Geraueoh binding the Dorohaesser of the valve tea equal or greater than 0.8 times the nominal width of the connection line is, but at least 13 bb.

A real feature of a low-noise faucet, of course The invention consists in a per se known, behind the valve part (in flow direction) arranged struungavid «r5tasd. Bisser limits the permanent water flow to one pre-bostimat value and thus reraalter at the same time daa Noisy For a single resistance - without the associated one Faucet - may according to the invention with a flow Sound?> 0 l / min that measured according to BIS 52 218, pre-standard 1968 Noise level should not exceed 15 dB (A).

A third necessary feature of the invention is a low-drainage facility Inflow of water sum Yentilsits · In some pallets this requirement is due to the simple structure of the valve has already been fulfilled. With other designs, such as i.B. Bath fittings, however, are special built-in components necessary. In the case of single faucets, the means must also be diverted to divert the water, sometimes to drain the tub, sometimes to total Shower head, designed to be aerodynamically favorable.

Finally, a final feature of the invention is that the hole for the water flow in the vicinity of the Ventllsitses widens in the direction of this funnel-like where the surface lines of the extension are either straight or slightly curved.

According to Fig. 1, the inflow to valve seats 1 with a diameter d_ takes place via a connection line 2, the diameter of which d _{r is the} same as that of the valve seat "B lot" which means that the requirement "d _{v is} equal to or greater than 0.8 ζ Hennveite der connection line * Hit 3 is the name of the valve disk which is moved via a spindle 4 and a handle 5. A perforated disk 6 is arranged at the Vaaser outlet, which acts as a low-noise flow resistance.

This perforated disk is provided with holes 7 according to FIG. 2 , the number and diameter of which result in the restricted flow rate limitation. (See the above-mentioned lit. «position)

In the case of the valve with swivel arm 8 according to Flg. 3 consists of Flow resistance from a tube 9, the diameter and length of which determine the desired flow rate. The-

This can only have a relatively small diameter, because otherwise the S-connection would be misshapen. In order to still obtain a valve seat of at least 13 in diameter, the bore or the channel 17 in the adjoining fitting part 18 is widened like a funnel in the direction of the seat 1. The surface lines of the enlargement are either straight or slightly moved.

The flush valve according to FIG. 5 has an inflow via a connecting line 2, which in its extension forms the valve seat »1.
