Abstract

A radiator isolation valve component comprises a tubular member 1 having a longitudinal passage 2 therethrough and adapted to connect a radiator with an inflow pipe or an outflow pipe, said member having a valve 8 therein capable of permitting or restricting flow through said longitudinal passage and having external means (10, Fig. 3) for actuating said valve. <IMAGE>

Description

RADIATOR ISOLATION VALVE This invention relates to a radiator isolation valve, and more particularly to a valve component which can restrict and contain the existing water in radiators.
In existing central heating systems, radiators have flow and return fittings which can be adjusted to change the rate of flow of water in the system. If a radiator has to be dismantled, for example, for repair or in the course of decoration, the entire central heating system has to be drained and then refilled afterwards, together with any necessary adjustment of antifreeze and inhibiting agents in the water. This is a time consuming operation. An object of the present invention is to eliminate this requirement to drain the system down when a radiator is disconnected.
The present invention provides a radiator isolation valve component, comprising a tubular member having a longitudinal passage therethrough and adapted to connect a radiator with an inflow pipe or an outflow pipe, said member having a valve therein capable of permitting or restricting flow through said longitudinal passage and having external means for actuating said valve.
Preferably, the valve is a ball valve rotatable about an axis perpendicular to the longitudinal passage and an end of which is accessible from outside the tubular member. In one particular embodiment, the externally accessible end of the ball valve is provided with a slot for engagement with a screwdriver, so that the ball valve can readily be turned on or off.
Reference is now made to the accompanying drawings, in which: Figure 1 is a longitudinal section of a radiator isolation valve component according to a preferred embodiment of the invention; Figure 2 is a plan view of the valve component; Figure 3 is a side elevation of the valve component; and Figure 4 is a diagrammatic representation of part of a radiator having the valve component included in the flow and return fittings.
The valve component shown in the drawings comprises a tubular member 1 having a longitudinal passage 2 therethrough. A lip 3 is provided at one end for engagement with internal screw-threads 4 on part of a conventional radiator fitting 5. The opposite end of the tubular member is itself provided with external screw-threads 6 for engagement with a corresponding existing radiator fitting.
As shown in Figure 4, one valve component according to the invention is situated at the inflow connection of the radiator 7 between the radiator and the inflow pipe fitting, and another valve component is placed in the corresponding position between the radiator outflow connection and the return pipe.
A ball valve 8 is positioned in the longitudinal passage 2. The valve has a bore therethrough and is rotatable on its seating in the longitudinal passage as shown by the arrows in Figure 1. In the position shown in Figure 1, the valve is open, but if it is rotated through 90", the central bore abuts against the valve seating and the valve is then closed. An end member of the ball valve is rotatably located in a transverse passage through the wall of the tubular member 1, and its end face 9 is thus accessible from outside the tubular member as shown in Figure 3. This end face is provided with a slot 10 for engagement with a screwdriver, to assist in rotating the valve between the open and closed positions.
In normal use of the central heating system, the respective ball valves 8 are in the open position. Flow of water through the radiator is controlled by the inflow and return fittings in conventional manner. However, when the radiator is to be disconnected, the valves 8 are first rotatated using a screwdriver to their respective closed positions. If the inflow and outflow fittings of the radiator are also turned off, then the radiator can be disconnected with no significant loss of water from the system. In particular, the water within the radiator itself remains contained therein. When the radiator has been replaced, the respective valves 8 can then be turned on again in corresponding manner.
The present invention thus eliminates any requirement to drain the central heating system down. Time is saved when removing radiators from wall support brackets.
When disconnecting radiators, there is no loss of water from the central heating system and the integrity of the antifreeze and inhibiting agents in the water is maintained.
Any necessary bleeding of the system after re-installing the radiators is minimised. Individual radiators can readily be disconnected from a central heating system and then replaced, for example in the course of decoration. The spillage of water from the radiators in the course of such operations is minimised.

Claims (4)

1. A radiator isolation valve component, comprising a tubular member having a longitudinal passage therethrough and adapted to connect a radiator with an inflow pipe or an outflow pipe, said member having a valve therein capable of permitting or restricting flow through said longitudinal passage and having external means for actuating said valve.
2. A radiator isolation valve component according to claim 1, in which the valve is a ball valve rotatable about an axis perpendicular to the longitudinal passage and an end of which is accessible from outside the tubular member.
3. A radiator isolation valve component according to claim 2, in which the externally accessible end of the ball valve is provided with a slot for engagement with a screwdriver, so that the ball valve can readily be turned on or off.
