Description
_1_ 2 0 01 2 2 7 Radiator Valve 1.~'itting The invention relates to a radiator valve fitting comprising a housing having a screw-in socket, a supply passage extending axially thereto and at least one discharge passage branching off between the screw-in socket and suppl;,r passage, and a valve insert housing having a bore, an inlet connecaion piece extending axially thereto and projecting into the supply passage, at least one radial outlet aperture and an external screwthread for screwing the valve insert into the screw-in socket, the end of the housing bore being provided with a valve seat between the inlet connection piece and outlet aperture and an axi~~lly movable closure element cooperating with the seat.
Such a radiator valve fitting is known from DE-PS 36 00 130. The outlet aperture is arranged near where the discharge passages branch off, so that the water can flow practically without hindrance from the supply passage when the valve is open, through the inlet connection piece and into l~he discharge passages. The spacing between the outlet aperture and the end of the valve insert housing projecting from the screw-in socket is relatively large. The valve insert housing is provided with a pin that can be actuated by a thermostat attachment. The fitting is fixed to the radiator or may even be part o:E it. The actual valve is disposed in the valve insert housing where the valve seat and valve closure member are provided.
~n~a ~qF' _2_ 20 01227 There is an increasing demand for bE~ing able to set the maximum flow through a radiator, the so-called k~ value, directly at the valve. Setting basically takes place during assembly of the radiator but subsequent adjustabilit:~ is an advantage.
Such a possibility of adjusting the k~ value is known from DE-PS
33 00 624. In this case, the flow section of the outlet aperture is changed by a pre-setting insert which can be operated from the end of the valve. In this known valve, however, the valve seat is provided in the housing of the fittin~~ and not in the valve insert housing. The screw-in socket is generally considerably shorter than in valves of the aforementioned kind. Such a valve will therefore always be useful if the flow is to be influenced in a more or less straight pipe. This valve is not, however, usable for so-called two plate radiators in which the supply line extends between the two plates up to the valvES, the discharge passages are perpendicular thereto and the valve with actuating attachment is at least partially arranged between the plates. For such radiators, a valve of the aforementioned kind will be necessary.
However, since in such a valve the screw-in socket is longer and also varies in length for different makes of radiators, the pre-setting inserts known from DE-PS 33 I)0 624 cannot be used in the valve inserts known from DE-PS 36 00 130.
It is therefore the problem of the present invention to provide a radiator valve fitting in which one cyan use a pre-setting insert ~n~a r of the kind used for radiator valves having a valve seat as part of the fitting. This problem is solved in a radiator valve fitting of the aforementioned kind in that the size of the outlet aperture is adjustable with the aid of a pre-setting insert, that the valve seat and outlet aperture are disposed at the level of the external screwthread, and that the valve insert housing is flattened near the outlet aperture, the external screwthread being interrupted.
One can thereby employ the known pre-setting insert. Since this is relatively short, the valve seat .and thus the outlet aperture are transposed deeply into the screw-in socket, namely into the region of the external screwthread. One thereby ensures that always the same pre-setting insert cyan be employed regardless of the length of the screw-in socket. 'This insert can therefore be manufactured in larger numbers, thereby reducing the production costs. The flattened region of the valve insert housing in which the outlet aperture is arranged provides an adequate discharge cross-section between the valve insert housing and the bore of the screw-in socket. This cross-section is considerably larger than in a bore that is simply led through the screwthread. The flat can, for example, be produced by milling or grinding. Naturally, there are limits as to how much screwt:hread can be removed and how closely one can approach the valve ;peat. However, it has been found that, despite the interruption of the screwthread for making an adequately discharge cross-section available, a sufficient s8n~a retaining force is applied by the screwthread. Depending on the form of the valve fitting, the inlet connection piece projects into the supply passage to a greater or lesser extent. The valve insert housing can therefore be emp:Loyed for different radiator valve fittings which vary in the length of the screw-in socket.
In every case, it is ensured that the supply passage is sealed from the discharge passage by the inlet connection piece which has a certain length.
In a preferred embodiment, a circumferential projection is provided on the side of the external screwthread remote from the inlet connection piece. This proje<aion fulfils two functions.
On the one hand, it brings about part of the seal to prevent the water or other heating liquid from flowing out of the valve fitting. On the other hand, the projection serves as an abutment to define the depth up to which the 'valve housing element can be screwed into the screw-in socket.
To make the discharge cross-section as large as possible, the outlet aperture is formed by a radial bore having part of its cross-section opening into the housin~3 bore, the remaining part of the radial bore cross-section comprising a base which is formed below the valve seat. Although a round drill is employed, this permits one to achieve a discharge aperture having a cross-section which is semicircular or a different part of a circle. The cross-sectional area of the discharge aperture is thus larger than ~n~a for a bore which is merely provided between the valve seat and the projection.
Advantageously, the base of the radial bore is curved outwardly.
The bounding line between the base of the radial bore and the housing bore preferably forms a section of a circle so that the valve seat is in its plane alway~~~ surrounded by a strip of substantially constant width. Closure members of different sizes can therefore be employed.
To reduce noise, the transition between the wall and base of the radial bore is rounded off. This provides better conditions for avoiding the sources of noise.
In a preferred embodiment, the pre-setting insert is formed by a skirt of which the lower edge rises circumferentially relatively to a plane perpendicular to the longii~udinal axis of the valve and which is rotatable about the longitudinal axis of the valve. This brings about a relatively simply way of adjustment. By turning the valve setting insert about the longitudinal axis of the valve, the discharge cross-section can be increased or reduced.
Preferably, the transition between the external diameter of the housing in the region of the screwthread and the smaller external diameter of the inlet connection piecE~ is adjacent to the external screwthread. For one thing, this saves material for the valve ~n~a w_ 20 0~22~
insert housing. For another, the largest possible discharge cross-section is made available for the water flowing through the valve into the radiator. Even if the constriction is still located in the inlet connection piece, the water is not excessively braked or throttled by the inlet connection piece.
Advantageously, the transition is Formed by a shoulder which directly adjoins the screwthread and has a directly adjoining cone. This ensures that the screwthread has a sufficiently large diameter over an adequately long 7Length whilst the cone can readily have a smaller maximum diameter without detrimentally influencing the valve seat which, of course, is disposed in the region of the external screwthread.
An example of the invention will now be described in conjunction with the drawing of which the single figure is a cross-section through the radiator valve fitting with valve insert housing.
A radiator valve fitting 1 comprises a housing with a screw-in socket 2, a supply passage 3 and two discharge passages 4, 5 which branch off between the screw-in sockei~ 2 and the supply passage 3.
The illustrated radiator valve fittin~~ serves to control a circuit for the heating liquid in a two-platE~ radiator in which a supply conduit is connected to the supply p<~ssage 3. The two plates of the radiator are connected to the two discharge passages 4, 5.
~n~a ._ ~ 20 01227 Screwed into the housing of the fitting, there is a valve insert housing 6 having a shank carrier 7 with a housing bore 8 and an inlet connection piece 9. The inlet connection piece 9 projects from the screw-in socket 2 into the supply passage 3. The inlet connection piece 9 is sealed from th~~ supply passage 3 by a seal 34. The shank carrier 7 is connected to the inlet connection piece 9, for example by a sealed s~~rew connection. The inlet connection piece comprises an external screwthread 11 with which the valve insert housing 6 is screwed into a complementary screwthread in the screw-in socket 2. Above the screwthread 11, i.e. on the side remote from the .supply passage 3, the valve insert housing is provided with a circumferential projection 35 which abuts a corresponding circumfe:rential projection 39 within the screw-in socket 2. The valve insert housing 6 is sealed in the screw-in socket 2 by a seal 33.
The bore 8 of the housing of the shank carrier 7 is extended by a bore 36 of the inlet connection piece 9. A valve seat 12 cooperating with a closure element 13 is disposed at the base of the housing bore 8, i.e. at the transition between the housing bore 8 and the bore 36 of the inlet connection piece 9. When the closure element 13 is pressed onto thE~ valve seat 12, the path for heating liquid from the supply passage 3 into the discharge passages 4, 5 is blocked. The valve seat 12 is substantially at the level of the external screwthread 11.
~n~a 20 0'!227 y _8_ Directly above the valve seat, there is an outlet aperture 10 through which the heating liquid can flow from the supply passage 3 to the discharge passages 4, 5 when the closure element 13 is retracted. The outlet aperture 10 is likewise disposed in the region of the external screwthread 11. To make an adequate discharge cross-section available for the heating liquid, the valve insert housing is provided with a flat 15 in the region of the external screwthread 11 at the ci.rcumferential position where the outlet aperture 10 emerges. Although this interrupts the screwthread il, the remaining part ensures adequate fastening of the valve insert housing 6 in the fitting 1. Through the flat 15, there is a bore 16 which at least partially opens into the housing bore 8. The remaining part of the bore 16 comprises a base 17 disposed beneath' the valve seat 12. This makes the outlet aperture 10 larger, namely broader, than if only one bore were to be provided with a diameter corresponding to the spacing between the valve seat and the projection 35. The base 17 of the bore is spherically rounded off so that the valve seat 12 is surrounded by an annular spherical surface having a substantially constant width over the entire circumference. This enables one to employ different closure elements 13 without: having to make a new valve seat 12 each time. The transition between the base 17 of the bore and the wall l9~of the bore is rounded off at 18 so that the outflowing heating liquid produces as little noise as possible.
The inlet connection piece converges directly adjoining the ~n~a _g_ external screwthread 11, on the one hand by a projection 20 and on the other by a cone 21. Since the inlet connection piece 9 projects to a certain extent into the screw-in socket 2, one thereby ensures that it will not excessively impede the outflowing heating liquid.
The closure element 13 is secured to a shank 22 which can be pressed with the aid of pin 32 onto t:he valve seat 12 against the force of a spring 23. The pin 32 ins actuated by a thermostatic valve attachment (not shown) which c<~n be secured to a neck 27 of the shaft carrier 7 of the valve insert 6.
As is usual, the valve insert 6 has ~;ecured to it a securing ring 24 having a lug 37 engaging in a groove 25 of the screw-in socket 2.
The valve closure, element 13 is surrounded by a pre-setting insert 14 which is rotatable about the longitudinal axis of the valve with the aid of a setting element ;Z6. It can be driven by a knurled wheel 29 which is pulled upw~~rdly against the force of a spring 28 so that its teeth 30 engage with corresponding teeth 38 of the setting element 26. In other respects, the construction of the actuating device of the setting ~slement is as shown in DE-PS
33 00 624.
The pre-setting insert 14 has a skirl: which is circumferentially ~n~a -1~-chamfered relatively to a plane perpendicular to the longitudinal axis of the valve. Thus, when the pre-setting insert is turned, it closes the outlet aperture 10 to a greater or smaller extent.
This enables one to determine the maximum throughflow for the heating liquid.
Depending on the length of the screw-in socket 2, the inlet connection piece 9 projects into the supply passage to a larger or smaller extent. Nevertheless, the elements necessary for actuating the valve closure member 13 and the elements necessary for actuating the pre-setting insert 14 will always have the same relatively short structural length. Although the heating liquid might therefore have to traverse a somewhat longer path, the latter is not impeded by the valve insert housing 6 because the flat 15 makes an adequate discharge cross-section available between the valve insert 6 and screw-in socket 2.
