Abstract

A radiator valve comprises a housing (1) on which are arranged a pipe union (11) for connection to the radiator and a screw socket (13) for receiving the first closure piece (4), which is arranged on a hollow valve spindle (3). The first closure piece (4), together with a valve seat (33) in the housing (1), forms a choke-like preset device for the throughflow. To allow the line or radiator to be emptied through the hollow valve spindle (3), the hollow valve spindle (3) contains a second valve closure piece (5), which can be actuated from the outside against the force of a spring and moved forward from the outside with regard to a corresponding valve seat in the valve spindle (3). The second hollow valve closure piece (5) is double acting and can be moved, with its end (52) opposite the discharge valve seat (33), through the first valve closure piece (4) toward the housing valve seat (14). A controller (9) which acts on the second valve closure piece (4) can be placed on the valve.

Description

Radiator valve

No content

The present invention relates to a radiator valve mainly used for backflow in a straight sheet or inclined sheet manner in a heating apparatus having a plurality of radiators and various tubes. Such a radiator valve used to shut off the pipe can drain the corresponding part of the installation.

Such a radiator valve is known from German Utility Model No. 71 11 825. In the case of the radiator valve, the hollow spindle used for presetting of the flow rate is tightened in the socket-like member of the housing, which is pushed against the valve seat in the housing by the spindle cap for blocking and presetting. Can lose. A ball valve is installed in the hollow valve spindle, and the ball valve can drain the pipe or the radiator. The ball is pushed against the pressure of the spring from the outside by a screwable drainage device from the outside, thereby separating it from the valve seat inside the valve spindle. The front part of the valve spindle is used for presetting.

By appropriately presetting with such a radiator valve, the necessary operating conditions in the tube are given. However, in larger installations, it is often not sufficient to pre-perset once perfusion because the operating conditions change. In this case, control valves, usually thin-film regulators, are usually installed in corresponding places. This additional installation requires a large assembly cost.

It is an object of the present invention to simply provide a radiator valve that can be combined with a pressure regulator.

This object is achieved by a radiator valve according to the invention.

The radiator valve of the present invention, which can be used as a shutoff valve with drainage function and presetting potential, can be provided with a regulator without assembling the valve housing or the upper part. The corresponding actuating member of the regulator is inserted into the hollow valve spindle and acts against the second closure member in the valve spindle. Thus, the radiator valve can be simply changed to a control valve.

According to a preferred embodiment of the invention, the regulator is installed at the outer end of the valve spindle. Thus, the regulator is independent of the housing, and preferably can be used for valves of different sizes having only the same shape of the valve spindle end and having different housings.

In another preferred embodiment of the present invention, the valve is formed so that the presetting can be seen from the outside. More specifically, the spindle cap and the indicator ring form a presetting indicator which can be seen from the outside.

Hereinafter, the present invention will be described in more detail with reference to the embodiments illustrated in the accompanying drawings.

FIG. 1 is a longitudinal sectional view of a radiator valve formed of a shut-off valve in which presetting is made, and FIG. 2 is a longitudinal sectional view showing a combination of a radiator valve according to FIG. 1 and a thin film regulator installed on the valve spindle.

1 shows a housing 1 of a radiator valve. In the housing 1 a connecting sleeve 11 and 12 face each other, the connecting sleeve 11 and 12 being a tube or radiator. Laid out. The socketed member 913 is used to receive the tightened valve top 2. The valve seat 14 is formed in the housing 1, and the 1st closing member 4 provided in the valve spindle 3 opposes the said valve seat 14. As shown in FIG. In principle, the position of the first closure member 4 relative to the corresponding valve seat 14 determines the presetting for perfusion. The radiator valve may be blocked by the first closing member 4. In the axial hollow part 31 of the valve spindle 2, the second closing member 5, which acts in duplicate, can be pushed against the pressure of the spring 6. The upper end 51 of the closing member 5 forms a drain valve together with the valve seat 33 in the hollow spindle 3. The upper end 51 of the second closing member 5 may be separated from the valve seat 31 by a drainage device not shown. For drainage, water enters into the hollow part 31 of the valve spindle 3 from the tube or radiator through the second closure member 5 and flows out of the drainage device therefrom. The hollow part 53 in the second closing member 5 is open toward the housing. Since the hollow part 53 ends below the upper end 51 of the second closing member, the valve seat 33 is closed in the state shown in FIG.

The opposite closing member end 52 protrudes outwards through the first closing member 4 and the protruding portion defines the contour of the first closing member 4 and the throttle gap with the closing member 4. Determine. At the end of the valve spindle 3, which protrudes from the valve upper part 2, a spindle cap 8 is provided on the rotary follower 32 and protected by a cap 82 provided thereon. The cap 82 simultaneously closes the hollow valve spindle 3.

Presetting takes place after the cap 82 and spindle cap 8 are removed. Upon removal, the valve spindles 3 do not move. Then, when the display ring 7 is rotated, the presetting nut 10 engaged with the display ring 7 and the adjustment ring 10a therein are pushed and the screw spindle 3 is driven in the axial direction. The section 21 in the upper part of the valve 2 is used for the corresponding rotary driven connection with the corresponding form of the valve spindle 3 in this section. A screw portion 22 is formed outside the upper valve portion 2, and the display ring 7 is engaged with the screw portion 22.

As shown in FIG. 2, a regulator, preferably a thin film regulator 9, may be installed on the outer end of the valve spindle 3 with the section 34 used for receiving the cap 82. . The cylindrical case 91 belonging to it is inserted into the shoulder 81 of the spindle cap 8. An actuating member 92 is fixed to the adjusting member, ie, in the case of a thin film regulator, in the form of a tube. The actuating member 92 is inserted into the hollow valve spindle 3 and the free end thereof has a second closing member. 5) to act against. By this actuating member, the end portion 52 of the second closure member 5 is pushed in the direction of the valve seat 14 in the housing 1 to regulate perfusion.
