The regulation concerns a thermostat-controlled flow control valve for heating radiators or air conditioning convectors, for the the desired room temperature is set with the help of a cark by turning an adjustment handle on a temperature scale can be.

iheriiiostat-controlled valves for radiator heating or As is well known, air conditioning systems have the task of influencing of the heating or coolant flow within a liaumes to maintain a desired temperature, which of course can vary from room to liauiri. Therefore, the mentioned valves an adjustment option for the setpoint of the Room temperature. Often a direct is used for the setpoint adjustment Used scale indicating temperature degrees, relative to the

With a single valve started, the degree to which the bulwark scale can be reduced consists in the fact that the scale attached to a Jinatellhanu handle of a valve can be displaced relative to that of a toothed crown. For this purpose, the land handle must be removed from a valve and attached to it as well, it has now been inclined to cause damage to the upper part of the valve, especially if it is made of plastic for reasons of insulation. Furthermore, the practice has shown that aaj aie schilaer'üe. «Rt aer liaci.calibration for laypeople, as this very often undertakes, is too complicated. Furthermore, the possibility of adjusting the setpoint value in this known valve is limited by the tooth pitch, so that in cases in which the characteristic of the thermostat is not linear as a function of the temperature range, in temperature ranges in which the temperature range

If the valves are manufactured in large series, then he _t :: ebc-, i throughc ^. the discovery still has additional advantages. It isc i: .B. possible for a series of valves with washers
to use the most varied of imprints, so that, for example, the scales can be either in ⁰ O (Celsius) or in ° I ⁽¹ (Fahrenheit))
the plastic discs, as is customary in the branch, are used to print the names of the various companies that have produced the heating or air conditioning system.

If wax elements are used as thermostats to control the valves, it happens that during the transition

The valve body 1o works to adjust the flow cross-section with de:.: Valve seat 21, which has been cast with the housing 3 in a btüctc. The housing 3 also has a connection opening 22 and 2 each for the supply and transfer of the heating medium.

The nut, 1, which is screwed onto the thread 4 of the lower valve plate, engages with its upper handle on a shoulder 25 of the insulating body α 2o (J ¹ Ig. 2) of the 'upper valve part. The insulating body 26 consists of a plastic with heat-insulating properties in order to protect the thermostat 27 placed on the valve from outside against temperature influences which are exerted by the lower valve part made of Iletall through which the heating medium flows. The openings 2y distributed on the circumference of the insulating body 2υ, which allow air to circulate in the cavity 33 of the insulating body 26, serve the same purpose. On its upper bark, the insulating body 26 has an external thread 28, into which a mating thread in the interior of the adjustment handle 30 engages. This thread is used to adjust the setpoint temperature by turning the adjustment handle 30,
