Description

The invention relates to a radiator valve comprising a valve housing equipped with a flow valve for heating medium and a storage device for a removable and adjustable valve closure in order to convert manual controls to controlled operation using the original radiator valve housing.

BACKGROUND OF THE INVENTION

In current heating systems, valves are predominantly used where by manually rotating the valve spindle 90 degrees around its own axis, the spindle flow opening is set perpendicular to the flow direction, thereby closing the spindle.

Exact room temperature control is not possible with these radiator valves. Therefore, the old, manually operated radiator valves were replaced with thermostatically controlled valves.

Operation with thermostatically controlled radiator valves allows optimum control of the room temperature and includes the action of a foreign temperature, such as the influence of solar radiation on the room temperature. In this way, savings can be achieved that reduce energy consumption. These advantages are known and the thermostatic valves themselves have a known position in technical development.

The replacement of manually operated valves with thermostatic valves of known design is associated with considerable labor costs and financial expenses.

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

When replacing it is not possible to avoid the necessity of separating the pipeline from the radiator or even removing the radiator body. Furthermore, it is often necessary to adapt a new valve, seal and reconnect to the radiator body, which is quite expensive.

SUMMARY OF THE INVENTION

According to the invention, the above mentioned drawbacks are overcome by a radiator valve consisting of a valve housing with a flow-through valve and a thermostatically controlled valve closure. The body of the thermostatically actuated valve closure has external dimensions corresponding to the internal dimensions of the storage device. The body is equipped with an inlet and an outlet opening, in the direction of the flow opening. 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 hold it in the open position, and the thermostatic force acts on the pin.

The advantage of the solution is that it is not necessary to separate the pipeline from the radiator for the conversion. All connections between the radiator, valve and pipe remain intact. The heating radiator must not be released from the wall. The possibility of reusing the original valve housing avoids the expense of a new valve housing or possibly a whole new valve. Furthermore, the labor costs associated with the installation of commonly used thermostatic valves will be reduced.

BRIEF DESCRIPTION OF THE DRAWINGS

The invention is further described by way of example and 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 is an overall assembly of a mounted, thermostatically controlled valve closure in elevation and partial cross section, mounted in a radiator valve housing;

DETAILED DESCRIPTION OF THE INVENTION

As shown in FIG. 2, the radiator valve comprises a radiator valve housing 22 in which an internal thread 37 is formed 20 perpendicular to the axis. The flow is provided by the inlet pipe 24 and the outlet pipe 23. This radiator valve is shown in FIG. 1 is an associated mounted thermostatically operated valve closure whose dimensions in terms of connection threads correspond to the dimensions of the valve housing of the original valve.

As can be seen from FIG. 1, the body 1 is provided with inlet openings 18, 19 and an outlet opening 3. Between the inlet openings 18, 19 and the outlet opening 3 is a valve seat 17 over which there is a 30 closure part 15 with gasket 16, the closure part 15 being spring 11 held in the open position.

The body 1 is provided on the upper part with an external thread 6, under which a groove 4 for receiving the sealing ring 5 is formed. The inner part of the body 1 is provided with a through axial bore, which is tapered twice during its course. By this narrowing of the bore, three chambers are formed inside the body 1, which lie in one axis but have three different diameters.

The first shoulder 14 defines a first chamber having the largest diameter 40 and having an internal thread 7.

A spring chamber is screwed into this chamber

13. The shoulder 14 serves as a stop on the screwed-in spring chamber 13. The second shoulder, which narrows the body bore 1 again, forms the valve seat 17. The first shoulder 45 and the second shoulder forming the valve seat

17, lie at a precisely defined distance from each other.

This distance is such that the closure member 15, when lifted, closes the valve seat 17 tightly.

The chamber located between the first shoulder 50 14 and the valve seat 17 forms the valve chamber 2.

In this valve chamber 2 a radial outlet opening 3 is formed above the valve seat 3. Underneath the valve seat 17 also radially but on the opposite side of the outlet opening 3 is an inlet opening 55 18 which opens into a further axial bore of the body 1. Inlet opening 18 it may be arranged at an angle of 90 ° to the outlet opening 3, or it may be parallel to it. Advantageously, the inlet opening 18 may be formed by two orifices which cross in the flow direction 60 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 openings will be closed by the body wall 1. The body 1 is terminated in the axial direction by an inlet bore 19.

SK 278397 Β6

This arrangement of the two openings 18, 20 ensures that the same body 1 can be used for both known valve shapes. The axial inlet bore 19 is intended for corner valves. An additional radial inlet 18 is provided for through valves. The face of the body 1 is provided with a groove 12 whose radial direction coincides with the radial direction of the inlet opening 18 and the outlet opening 3. This indicates the flow direction, which is important for assembly. This groove 12 also serves to enable the body 1 to be screwed or unscrewed into the valve housing 27 of the radial valve by means of a suitable key. The closure part 15 is provided with a pin 10 which opens into a spring chamber 13 screwed in the body 1 up to the first shoulder 14. The spring chamber 13 is formed of two parts which are screwed together by the open sides. Inside the spring chamber 13 there is a spring 11 which, when opened, actuates the pin 10. A support washer 21 is provided in the groove of the pin 10. The spring 11 is biased between the support washer 21 and the bottom of the spring chamber 13. The biasing spring 13 lifts the seal 16 from the valve seat 17 for as long as the pressure is not applied to the pin 10 by the radiator thermostat. The spring bias 11c is selected so that the valve can be closed by conventional thermostatic elements.

The pin 10 is actuated by the thermostatic mechanism shown in FIG. 3 and is attached to the body 1 via the adapter ring 8. The thermostatic mechanism moves the pin 10 axially and thus presses the closure piece 15 with the seal 16 against the valve seat 17. This reduces or closes the flow. The thermostatic mechanism 25 comprises a housing 28, which is an internal shoulder 26 located in the annular groove 27 of the adapter ring 8. The housing 28 is then secured to the valve housing 22 of the radiator valve. In the housing 28, a rotary knob 29 is provided with a thread 31 and screwed into the sleeve thread 30 and rotates in both directions 36. The rotation is determined such that the rotary knob 29 performs at least a stroke 35 corresponding to the stroke of the closure member 15 between closed and fully open position. A pusher 3 is inserted between the rotary knob 29 and the protruding end of the peg 10 to convert the rotary movement to the pin 10. The pusher 33 is supported on the pusher 33 seated on the free end of the pin 10. The pusher 33 is surrounded by a bellows 34, which is filled with an expandable mass that changes its volume depending on the temperature. The bellows 34 can expand in the axial directions, whereby the closure member 15 is pressed against the valve seat 17 once the room temperature has reached the desired height.

Industrial usability

The invention is useful in converting existing heating systems with manual valve stem control to thermostatically controlled valves.
