Abstract
When in an OFF position, a cam c is driven by motor e to where its profile applies pressure via a rod b to a valve stem z causing the valve v to close (Fig. 5). When in the ON position, the cam c is driven to where the combined length of the rods a, b plus the diameter of the cam c allows the thermostat t to operate upon the valve in a normal manner. In a second embodiment (Fig. 6), a compression caliper pushes down on a slotted rod which in turn closes valve v, and when driven in the opposite direction allows the thermostat t to take control of the valve v and operate as normal. The battery powered timer is fitted between a valve v and a thermostat t of a conventional thermostatic radiator valve allowing individual radiators to be controlled.
Description
DESCRIPTION
Thermostatic Radiator Valve Timer Insert The "Thermostatic Radiator Valve Timer Insert" is designed to be fitted to hot water heating system radiators that have thermostatic radiator valves already fitted.
A standard hot water heating system (central heating) has only one timer in the system which turns the whole system on and off as required. This means that any room in the house not being used is still being heated because other rooms in the house are in use and being heated.
The "Thermostatic Radiator Valve Timer Insert" is fitted to any radiator which already has a thermostatic radiator valve fitted and allows that individual radiator to be controlled separately from all others in the system by both temperature and time. This saves the cost of heating the unused room and makes more heat available to the remaining radiators.
There are no plumbing or electrical skills required to fit the "Thermostatic Radiator Valve Timer Insert" to a pre-existing thermostatic radiator valve.
The "Thermostatic Radiator Valve Timer Insert" is a battery powered device.
There are two embodiments to the invention.
The first embodiment of the invention will now be described with reference to the accompanying drawings which are: Fig 1 is a representation of a standard thermostatic radiator valve. This is used solely to demonstrate how and where the invention is to be installed.
Fig 2 is a representation of a standard thermostatic radiator valve separated as intended by the manufacturer. This is used solely to demonstrate how and where the invention is to be installed.
Fig 3 is a representation of the first embodiment of the invention fitted between the two separate parts of the original thermostatic radiator valve.
Fig 4 is a representation of the working parts of the first embodiment of the invention when it is in the ON position.
Fig 5 is a representation of the working parts of the first embodiment of the invention when it is in the OFF position.
The "Thermostatic Radiator Valve Timer Insert" is an insert device intended to be fitted between the valve (v) and the thermostat (t) of conventional thermostatic radiator valve (fig 1) which is generally supplied as two separate units (fig 2), the valve (v) and the thermostat (t) that normally fit together by means of a ring clamp (x).
The "Thermostatic Radiator Valve Timer Insert" is fitted to the thermostatic valve (fig 1) by first unscrewing the ring nut (x) and removing the thermostat (t) from the valve (v) then the "Thermostatic Radiator Valve Timer Insert" is placed onto the valve (v) and the ring nut (y) tightened to fix it to the valve (v) and finally the thermostat is fixed to the top plate (w) of the "Thermostatic Radiator Valve Timer Insert" and the ring nut (x) tightened to fix it to the "Thermostatic Radiator Valve Timer Insert" top plate (w).
The "Thermostatic Radiator Valve Timer Insert" when installed between the thermostat (t) and the valve (v) (fig 3) closes the valve Cv) independently of the thermostat (t) when the radiator is not needed without adverse effect on the rest of the heating system.
The first embodiment of the "Thermostatic Radiator Valve Timer Insert" (fig 4 and 5) consists of two rods (a) and (b) and a cam (c). The cam (c) is mounted on a square shaft (d) which is rotated by an electric motor (e) via a worm (f) and wheel drive (g), the wheel drive (g) being fixed to the square shaft. The cam (c) has a rectangular slot (h) cut in it through which the square drive shaft (d) passes this allows the cam (c) to move up and down on the square shaft (d) when the "Thermostatic Radiator Valve Timer Insert" is in the ON position (fig 4) as required by the operation of the thermostat but prevents such movement when the "Thermostatic Radiator Valve Timer Insert" is in the OFF position (fig 5) and holding the valve (v) closed.
The programmer (p) can be set to turn the radiator on allowing normal use of the radiator via its thermostatic radiator valve when required and off when the radiator is not required at all.
When the programmer (p) switches the "Thermostatic Radiator Valve Timer Insert" to the ON position (fig 4) the cam (c) is driven by the worm (f) and wheel (g) to where the slot in the cam (c) is vertical. With the cam (c) in this position any downward thrust from the thermostat (t) due to the room warming is transmitted via the rod (a) the cam (c) and the rod (b) to the valve stem (z) and closes the valve (v). When the room cools the return spring built into the valve (v) overcomes the downward thrust and moves the cam (c) and rods (a) and (b) upwards allowing the valve (v) to open and let hot water through the radiator to warm the room.
When the programmer (p) switches the "Thermostatic Radiator Valve Timer Insert" to the OFF position (fig 5) the cam (c) is driven by the motor (e) via the worm (f) and wheel (g) through 90 degrees to where it pushes down on rod (b) which in turn pushes down on the valve stem (z) thus closing the valve. In this position the rod (a) drops away from the thermostat (t) to prevent thermostat having any influence on the valves operation.
The important dimension in this the first embodiment of the invention is the lengths of the operating rods (a) and (b) and the diameter of the cam (c), when in the on position, which must be in total the same as the distance between the two connecting faces (qi) and (q2) (fig 4) of the invention and the free movement, in both directions, available to the operating rods (a) and (b) and the cam (c), when in the on position, which must be equivalent to the distance travelled by the valve stem (z) to close the valve (v) from the open position.
The second embodiment of the invention will now be described with reference to the accompanying drawings which are: Fig 1 is a representation of a standard thermostatic radiator valve. This is used solely to demonstrate how and where the invention is to be installed.
Fig 2 is a representation of a standard thermostatic radiator valve separated as intended by the manufacturer. This is used solely to demonstrate how and where the invention is to be installed.
Fig 6 is a representation of the second embodiment of the invention fitted between the two separate parts of the original thermostatic radiator valve.
Fig 7 is a representation of the working parts of the second embodiment of the invention when it is in the ON position.
Fig 8 is a representation of the working parts of the second embodiment of the invention when it is in the OFF position.
The "Thermostatic Radiator Valve Timer Insert" is an insert device intended to be fitted between the valve (v) and the thermostat (t) of conventional thermostatic radiator valve (fig 1) which is generally supplied as two separate units (fig 2), the valve (v) and the thermostat (t) that normally fit together by means of a ring clamp (x).
The "Thermostatic Radiator Valve Timer Insert" is fitted to the thermostatic valve (fig 1) by first unscrewing the ring nut (x) and removing the thermostat (t) from the valve (v) then the "Thermostatic Radiator Valve Timer Insert" is placed onto the valve (v) and the ring nut (y) tightened to fix it to the valve (v) and finally the thermostat is fixed to the top plate (w) of the "Thermostatic Radiator Valve Timer Insert" and the ring nut (x) tightened to fix it to the "Thermostatic Radiator Valve Timer Insert" top plate (w).
The "Thermostatic Radiator Valve Timer Insert" when installed between the thermostat (t) and the valve (v) (fig 6) closes the valve (v) independently of the thermostat (t) when the radiator is not needed without adverse effect on the rest of the heating system.
The second embodiment of the "Thermostatic Radiator Valve Timer Insert" (fig 7 and 8) consists of a drive shaft (I) that is threaded with a left handed thread from the middle of the shaft to one end of the shaft and a right handed thread from the centre of the shaft to the other end of the shaft Onto the bi-threaded drive shaft (I) two internally threaded calliper drivers (g) and (h) are fitted and to these are fitted calliper thrust rods (i) and (j) which are joined together at the thrust point (0), when the calliper drivers (g) and (h)converge the thrust point (o) moves downward and when the calliper drivers (g) and (h) diverge the thrust point moves upwards.
The operating rod (k) has a slot cut in it (fig 10) through which the compression calliper passes.
The programmer (p) can be set to turn the radiator on allowing normal use of the radiator via its thermostatic radiator valve when required and off when the radiator is not required at all.
When the programmer (p) switches the "Thermostatic Radiator Valve Timer Insert" to the ON position (fig 7) the drive shaft (I) is rotated by the motor (e) via the gear box (f) in such a direction as to cause the calliper drivers (g) and (h) to diverge thus moving the calliper pressure point (o) upwards away from its operating point on the operating rod (k) stopping it from influencing the normal operation of the thermostatic radiator valve.
When the programmer (p) switches the "Thermostatic Radiator Valve Timer Insert" to the OFF position (fig 8) the drive shaft (I) is rotated by the motor (e) via the gear box (f) in the opposite direction to previously causing the calliper drivers to converge, driving the pressure point (o) downward, pushing the operating rod (k) downward onto the valve stem (z) and closing the valve (v) preventing water flowing through the radiator.
The important dimension in this the second embodiment of the invention is the length of the operating rod (k) which must be the same as the distance between the two connecting faces (qi) and (q2) (fig 7) of the invention and the free movement, in both directions, available to the operating rod (k) which must be equivalent to the distance travelled by the valve stem (z) to close the valve (v) from the open position.
