Current status teChnikv! im - 1 ... ·. ·· !. I I M «

In existing heating devices, valves are predominantly used in which a manual spindle rotation of 90 degrees about its own axis adjusts the spindle flow opening perpendicular to the flow direction, thereby closing the spindle.

Bactual room temperature control is not possible with these radiator valves. Therefore, the outdated, manually operated radiator valves have been replaced by thermostatically controlled valves.

Operation with thermostatically controlled radiator valves allows optimum control of the room temperature and incorporates an external temperature such as the influence of solar radiation on the room temperature. Thus, savings can be achieved which reduce energy consumption. These advantages are known and thermostatic valves themselves are well known in the development techniques.

Replacement of manually operated valves by thermostatic valves of known design tends to involve considerable labor costs and financial expense.

However, new valves generally have a greater construction length than old valves.

During replacement, it is not possible to avoid the necessity of separating the pipeline from the radiator, or even removing the radiator body. Further, it is often necessary to adapt a new valve, to make a more sealed and reconnected connection to the radiator body, which is often costly.

SUMMARY OF THE INVENTION

According to the invention, a radiator valve consisting of a valve housing with a flow-through valve and a thermostatically controlled valve closure removes the above-mentioned drawbacks. The body of the thermostatically actuated valve closure has external dimensions corresponding to the internal dimensions of the receiving device. The body is provided with inlet and outlet openings that point in the direction. hole. A valve seat is provided between the inlet opening and the outlet opening, and a thermostatically controlled closing part with a gasket is provided against it. The pin of the closure member is surrounded by a spring to maintain it in the open position; the thermostatic force is acting opposite to the pin.

The advantage of the solution is that no separation of the piping from the radiator is necessary for the conversion. All connections between the radiator, the valve and the pipe remain intact. The heating radiator must not be released from the wall. The possibility of reusing an existing valve housing avoids the expense of a new valve housing or possibly a whole new valve. Furthermore, labor costs associated with the installation of commonly used thermostatic valves will be reduced.

An overview of the figure in the drawings

The invention will now be described in more detail with reference to the accompanying drawings, in which: FIG. 1 shows an exemplary embodiment of a valve housing with a body mounted in elevation and overall section, FIG. 2 is a front sectional view of a radiator valve housing; FIG. 3 overall assembly. mounted, thermostatically controlled valve valve cap in front view and partial cut, built into the radiator valve housing.

Example, Embodiment of the Invention

As can be seen from FIG. 2, the radiator valve consists of a radiator valve housing 22 in which an internal thread 37 is formed perpendicular to the axis. The flow is provided by the inlet pipe 24 and the outlet pipe 25. According to FIG. 1 is a thermostatically controlled valve closure, the dimensions of which, in terms of connection threads, correspond to the valve housing dimensions of the original valve.

As can be seen from FIG. 1, the body J is provided with inlet openings 18, 19 and an outlet opening 3. Between the inlet openings

18, 19, and a valve seat 17 is disposed through the outlet opening 3, over which the closure part 13 with the seal 16 is located, the closure part 15 being held in the open position by the spring 11.

Body. The inner part of the body is provided with a through axial bore, which is narrowed twice in the course of the course of the bore. This narrowing of the bore forms a unit of body J of the three chambers, which they lie in the center line but have three different diameters.

The first shoulder 11 defines a first chamber having the largest diameter and having an internal thread 7. A spring chamber 13 is screwed along this chamber. The first shoulder 14 serves as a stop for the screwed-in spring chamber 15. The second shoulder, which narrows the body bore J again, forms a valve seat 17. The first shoulder 14 and the second shoulder constituting the valve seat 12 lie precisely at a specified distance from each other. This distance is so great that the closure part 15 closes the valve seat 17 during its stroke.

The chamber located between the first shoulder 14 and the valve seat 17 forms a valve chamber 2. In this valve chamber 2, a radial outlet opening 2 is also formed above the valve seat 17, and a valve seat 17 is also radially disposed on the opposite side of the outlet opening 3. entry

4 an opening 18 which opens into a further axial bore of the body 1. The inlet opening 18 may be provided at an angle of 90 γΛ or the outlet opening 3, or it may be parallel to it. Advantageously, the inlet orifice 18 may be formed by two orifices that cross in the flow direction upstream of the valve seat 17, and depending on the design of the valve housing, whether it is a corner valve or a through valve, one of the two orifices will be closed. The body J is terminated in the axial direction by the inlet bore 19. By arranging the two openings 18, it is achieved that the same body J can be fitted for both known valve shapes. The axial inlet bore 19 is for corner valves. The additional radial inlet port 18 is for through valves. The end face of the body J is provided with a groove 12, the radial direction of which coincides with the radial direction of the inlet port 18 and the outlet port 3. This indicates the flow direction, which is important for assembly. This groove 12 also serves to screw the body into the valve housing 27 of the radial valve by means of a suitable key. The closure part 15 is provided with a plurality 10 which opens into a spring chamber 15 screwed in the body J up to the first shoulder 14. The spring chamber 15 is formed of two cups. These fogs are screwed together by the open sides. Inside the spring chamber 13 there is a spring 11 which, when opened, moves the pin into movement. An opaque washer 21 is located in the groove of the pin 10. The spring 11 is preloaded between the support washer 21 and the bottom of the spring chamber 15. The preloaded spring 13 lifts the seal 16 from the valve seat 17 as long as pressure is not exerted on the pin 10 by the radiator thermostat. Spring preload J1. is selected so that the valve can be closed by beige thermostatic elements.

The pin 10 is actuated by a thermostatic device as shown in FIG. 5 and is attached to the body via the adapter ring 8. The thermostat moves axially by a plurality of 10 and thus presses the closure piece 15 with the seal 16 against the valve seat 17. This reduces the flow closure. The thermostatic device 25 consists of a housing 28 which, by an internal shoulder 26, is located in the annular groove 27 of the adapter ring 8.

The housing 23 is then attached to the valve housing 22 of the radiator valve. In the housing 28 is provided a rotary knob 29 with a thread 51 and screwed into the sleeve thread 50 and rotates in both directions 56. The rotation is determined such that the rotary knob 29 performs a minimum stroke 55 that corresponds to the stroke of the closure member 15 between the closed and fully open positions. The push rod 55 is used to transfer the rotary movement to the pin 10, which is; The push rod 53 is supported by a push plate 53 seated on the free end of the pin 10. The push rod 33 is surrounded by a waveguide 34 which is filled with an expandable mass which changes in volume depending on the temperature. The bellows 34 can expand in the axial direction, whereby the closure member 15 is pressed against the valve seat 17 when the room temperature reaches the desired height.
