Mixing valve

The innovation relates to a mixing valve, especially for heating systems and return admixture, which consists of one Valve housing with at least three pipe connection pieces and a rotary valve arranged in the center with the relevant connection opening depending on the position of the turn pushes more or less releasing throttle flag.

Such mixing valves are well known and installed in every modern heating system, depending on the Conditions as a one-way or two-way mixer. It is also known that the rotary valve of such mixers with throttle vanes to provide that the inflow and outflow openings of the mixer depending on the position of the rotary valve more or cover less. _n

Since such mixers have to be provided for right and left connection, the equipping of the mixers with the Dopoeliaimen mentioned above means a ΛητνρΗίΐβ Fp-r + ip-imp ind Tingevune mir »- at least the rotary valve to meet all installation requirements to be able to suffice. Such double storage and different production is not only disadvantageous in this respect, but also never causes difficulties in delivery, because it happens again and again that mixers are either ordered incorrectly or incorrectly delivered.

The novelty is accordingly the reason for the problem, these disadvantages to be eliminated, i.e. a mixer should be created, of neither a different manufacturing north warehousing regarding the rotary valve is required, i.e. one that can be delivered and installed for both right and left connection.

This object is achieved with a mixing valve of the type mentioned, the nac> the innovation is characterized in that the rotary valve double the number of Droseelfannen in relation to the normally present flags in the opposite direction are cast breakable.

With this solution, there is no RoIDe for the mixer, whether it is to be installed in the left or right connection, since the throttle flags that are not required simply break off during installation The resulting break edge does not interfere with operation. The rotary valve is also not deformed by breaking off, because for such rotary valve as a rule

Non-ferrous metal alloys are used, which are raltively hard and can be broken easily ₀

The reference to "normally" existing flags means that with one-way mixers so far there is only one side flag, while with Dopr> same mixture on opposite edges of the Rotary valve on opposite sides each p-i.ne flag provided is.

The one-way mixer is now the rotary valve on one edge provided with two lanes that point to opposite sides and a total of four flags are cast on for two-way mixers. In consideration of a lower material loss, the mixing valve is advantageously designed so that the lugs with respect to the rotary valve body with a smaller wall thickness in such a way are designed so that the flow surfaces of the flags are in sliding contact with the sealing surfaces of the housing «

The mixing valve can also advantageously be designed in such a way that the lugs are broken off relative to the rotary valve body relieving longitudinal notches are offset.

The novel mixer is shown below in FIG Representation of exemplary embodiments explained in more detail.

In this illustration shows:

1 shows a one-way mixing valve in plan view; FIG. 2 shows an enlarged side view of the rotary slide valve in the mixer according to FIG. 1.

Pig. 3 another embodiment form of a rotary valve and Pig. 4 a further embodiment of a rotary valve.

In the figures, 1 or 1 ^f denotes different embodiments of rotary valves, which are rotatably arranged in the center of a mixer housing 5, which in the example shown is suitable for one-way admixture. 7 is the connection for the heating flow, 8 the connection for the heating return and 9 of the boiler flow. the sliders ^{(represented u.)} at abgedeekeltein housing from the handle 10, or if necessary with a servo motor set.

At slider 1 in Pig. 1, the valve shown is intended for right-hand connection, the breakdown 2 "(see Pig. 2) has already broken off along the K ^ aite 10.

In the rotary valve 1 according to FIG. 4, the lugs 2 'are kept thinner in their wall thickness compared to the rotary valve body, so that breaking notches 6 ¹ result automatically, as it were.

Such bridging notches 6 are advantageously provided on the other lugs 2

Claims (3)

School requirements: ^. Mixing valve, especially for heating systems and return admixing, consisting of a valve housing with at least three Roiir connection pieces and one in the center Rotary valve with the relevant connection opening depending on the position of the rotary valve more or less releasing throttle vanes, characterized in that on the rotary valve (1 * 1 ') twice the number of throttle pans (2) in Regarding the normally existing mishaps in each case opposite Are cast in the direction of breakaway, 2. Mixing valve according to claim 1, characterized in that the flags (2 ^! ) Are designed with a smaller wall thickness than the rotary valve body such that the inflow surfaces (3) of the flags (2) in sliding contact with the .- ^ sealing surfaces (4) of the housing (5). 3. Mixing valve according to claim 1 and / or 2, characterized in that the flags (2.2 ·) opposite the rotary valve body (1,1 ') are set off by longitudinal notches (6) which facilitate breaking off.
