Definitions
- This invention relates to valves for fluid temperature regulating systems and more particularly to water temperature regulating valves intended for use in hydronic heating systems, but the use of the invention is not restricted to that particular field.
- valve bodies configured to combine flaws of hot and cold fluids to provide mixed fluids having a controlled temperature are described in disclosures of patent specifications such as International Patent Application No. PCT/US02/27056 published as WO 03/019315.
- a water temperature regulating valve In hydronic heating systems the role of a water temperature regulating valve is to: (1) receive high temperature water from a boiler or similar heat source; (2) receive lower temperature water returning from the heating loops of the hydronic heating system; (3) output water at a constant temperature to the heating loops of the hydronic heating system by regulating the relative flow rates of the high and lower temperature water through the valve; and (4) ensuring that any additional water added to the hydronic heating system from the boiler or similar heat source is replaced by a corresponding amount of water being returned to the boiler or similar heat source (a requirement arising from the fact that the output water is going to a closed loop which returns the water temperature regulating valve). Additionally it is important that the water temperature regulating valve provide overall temperature control to the hydronic heating system so as prevent damage to floor structures or floor coverings. [0004] Regulation of the water temperature is achieved by a mechanism commonly used in tempering valves and thermostatic devices.
- the required flow passages to direct the high temperature water and lower temperature water to regulating gaps are formed by cast or mechanical channels within a brass valve body.
- a water temperature regulating valve including a valve body having a cavity in which mixing of fluids can occur, and provided with a hot fluid (or heated water) inlet adapted for communication with a source of hot (or heated) water, a cooled fluid inlet adapted for communication with an apparatus that has used the mixed fluid for heating, a mixed fluid outlet adapted for communication with an apparatus that uses the mixed fluid for heating, and a return fluid outlet adapted for communication with the source of hot (or heated) water, all inlets and outlets also being in communication with the cavity provided within the valve body, said cavity being provided with an insert in a sealing relationship with an inner surface of the said cavity, said insert having a central bore and also defining flow passages and being configured to direct the flows of hot fluid entering the cavity via the hot fluid inlet and cooled fluid entering the cavity via the cooled fluid inlet, the flow passages defined by the said insert interacting with moveable closure means to selectively permit, restrict or prevent the flows of hot fluid and cooled fluid into
- the required flow passages to direct the hot and cooled water to regulating gaps are formed by cast or machined channels within a brass valve body.
- casting is invariably the method chosen.
- a separate shell-like insert has been used to form or define all the flow passages within a simplified forged and machined valve body.
- the insert is shell-like.
- the flow passages are defined by ridges provided on the outer surface of the insert which ridges can enter into sealing relationships with the inner surface of the valve body. The ridges may be moulded onto or otherwise permanently affixed to the outer surface of the insert.
- the insert preferably is constructed of injection moulded thermoplastic moulded over with a thermo plastic elastomer (TPE) seal.
- TPE thermo plastic elastomer
- the TPE seal/thermoplastic valve combination allows for a dramatic reduction in weight, as the brass internals that would normally be used in the valve are replaced by a lightweight plastic insert.
- the brass valve body can then be a simple, thin shell with inlets and outlets. Further the invention allows for the application of a wider range of
- manufacturing technology is such as forging and the use of materials other than brass, such as plastics.
- the moulded TPE seal on the insert provides a static seal between the insert and an inner surface of the valve body.
- the general shape of the insert is a critical aspect of the invention.
- the static sealing face between the insert and the interior of the valve body preferably is tapered, instead of being a straight bore. This allows the insert to be placed almost into the fully assembled position before the TPE seal is compressed, thereby minimizing or preventing damage to the seal during assembly. Also, the taper results in a large amount of force pushing the seal into the interior of the valve body, which provides an improved seal, minimising the loss of sealing by compression set in the TPE material, as there will continue to be force pushing it against the interior of the valve body.
- the central bore of the insert is offset compared to the interior of the valve body which allows a greater outlet cross section for increased flow without affecting inlet flow, which is advantageous.
- the insert is provided with at least one cut-out, preferably a plurality of cut outs. communicating with the central bore of the insert, and at least one moulded recess, preferably a plurality of moulded recesses, on its outer surface, to permit communication between different inlets and outlets and the flow through of water during different phases of operation of the temperature regulating valve.
- the dimensions, positioning and orienting of the cut-out/s and moulded recess/es can vary according to desired behaviour or characteristics of the water temperature regulating valve.
- the overall design of water temperature regulating valves according to the present invention allows for more flexibility in effecting different outlet to inlet arrangements with the same valve body.
- the insert can have various shapes providing different inlet/outlet and performance characteristics while retaining the same valve body and other internal components.
- an O-ring In the course of assembling the valve, an O-ring is first positioned onto the insert, then an O-ring retainer is pushed into the insert and is held in place with a plastic snap fit.
- a dove tail groove is formed between the opposing faces of the insert and O-ring retainer.
- the dove tail groove for the O-ring prevents dislodgement of the O-ring during high flow velocity.
- Advantages include improved compression set, reduced sticking in the bore, replaceable components, full range of potable water approvals, greater range of temperatures, greater range of fluid resistance and cheaper to manufacture.
- the movable closure means preferably includes a thermostatic element cooperative with a piston, which is mounted on an upper surface of the thermostatic element and which piston can adopt a sealing relationship with the inner face of the insert and other parts of the valve.
- the piston is received within the insert and can move upwardly or downwardly with respect to the insert.
- the thermostatic element can be a known flat diaphragm element which expands and contracts in a known manner with changes in temperature. The interaction between the thermostatic element and piston is such that the expansion or contraction of the thermostatic element results in movement of the piston.
- the piston and the thermostatic element are constrained from displacement within the cavity of the valve body by a spring on the upper end of which the thermostatic element rides.
- the extent of upward movement of the thermostatic element is limited by the bottom end of a spindle passing through a cap mounted at the open end of the cavity of the valve body. Because of the advantageously increased flow resulting from the offsetting of the central bore of the insert with respect to the interior of the valve body, the amount of interaction between the upper end of the thermostatic element and the bottom end of the spindle is increased.
- a disc or button of material more durable than that of the spindle is provided in a recess provided in the bottom end of the spindle, to reduce wear on the bottom end of the spindle arising from interaction with the upper end of the thermostatic element.
- the spindle is connected to a temperature indicating knob assembly and passes through the cap, preferably via a cooperating screw thread arrangement.
- the extent of upward movement of the piston is limited by the bottom face of the cap.
- the knob of the knob assembly can be turned to indicate a particular temperature and the spindle rotates with the knob and, via the screw thread arrangement, moves upwardly or downwardly relative to
- the thermostatic element typically includes a non-expanding part and an expanding part, usually a wax, contained in a cup.
- a non-expanding part When the temperature of water surrounding the thermostatic element increases, the wax expands and pushes against a diaphragm within the thermostatic element which in turn transmits force and movement via an internal plug to a non-expanding internal piston. If the non-expanding internal piston is in contact with the bottom end of the spindle the thermostatic element and piston are pushed away from the underside of the cap. Conversely, when the temperature of the water surrounding the thermostatic element decreases, the wax contracts and the spring pushes the thermostatic element and piston towards the underside of the cap.
- the 4 port design of the water temperature regulating valve with integrated return to the boiler allows the valve to seal off the heated water inlet port while keeping the return from the manifold and supply to the manifold open. This allows the valve to seal off the hot water supply from the hot water system while leaving the pump running - therefore no additional pump protection cut off or pressure bypass valve is required when the hot (heated) water supply is closed off.
- the valve closes this automatically when the temperature increases above a certain level. This is a significant feature as it minimizes the risk of water spillage and/or heat damage to floors due to increased temperature levels.
- indexing flexible bumps on the locking ring provide protection against self-opening of the spindle as fluid pressure may cause it to self-open in extreme cases (due to unwinding of the screw thread).
- Plastic arms push bumps into corresponding grooves on the outer side of a hollow shaft descending from the underside of the knob resulting in additional force required to unscrew the spindle to the next groove on the knob.
- a temperature regulating valve according to the present invention may be used in other situations and with other fluids where temperature control in a closed fluid flow system is required.
- the materials used to construct such valves may have to be changed.

- FIGS 1 and 3 alone line H-H of Figure 3 showing the embodiment in operation when the hot water inlet has been shut off.
- valve body being identified by the numeral 12 and the insert by the numeral 24.
- the valve 10 includes a body 12 provided with an outlet (14) for supplying temperature regulated water to heating loops in a hydronic heating system (not shown), a cooled water inlet (16) for return of water from the aforesaid heating loops, a hot water inlet (18) for supply of heated water from a boiler (not shown), an outlet (20) for return of water to the aforesaid boiler, and a temperature control knob (22).
- valve 10 also includes a retaining nut
- the insert which is merely one embodiment of the insert of the present invention are shown in Figures 4a and 4e, inclusive.
- the insert preferably constructed from a thermoplastic material by injection moulding, is provided with a moulded over thermoplastic elastomer seal (40) (shown as cross-hatched in Figure 4). This seal (40) follows some of the contours of the insert (24).
- the insert (24) is also provided with a central bore (42), cut outs (44), (46) and recessed portions (48), (50) to permit communication between differing inlets and outlets and the flow-through of water during different phases of operation of the temperature regulating valve.
- the insert (24) is used to define all the flow passages within a simplified forged and machined valve body (12).
- Insert (24) is constructed of injection moulded thermoplastic moulded over with a thermoplastic elastomer (TPE) seal (40).
- TPE thermoplastic elastomer
- the brass valve body can then be a simple, thin shell with inlets and outlets, which provides savings in materials used.
- the static sealing face between the insert (24) and body (12) is tapered, instead of a straight bore (see figure 4e). This allows the insert (24) to be placed almost to its fully assembled position in the interior (13) of the valve body (12) before the TPE seal is compressed, preventing clamage to the seal during assembly. Also, the taper means there is a large amount of force pushing the seal into interior (13) of the body, which provides an improved seal, minimising the loss of sealing by compression set in the TPE material, as there will still be force pushing it against the internal face of the valve body (12).
- An offset central bore (42) of the insert (24) compared to the bore of body (12) allows a greater outlet cross section for increased flow without affecting inlet flow.
- the overall design allows for more flexibility in providing different outlet to inlet arrangements with the same body.
- the general shape of this design is a critical aspect of the temperature regulating valve.
- the insert (24) can have many different shapes providing different inlet/outlet and performance characteristics with the same valve body and internal components.
- the numeral 52 designates an O-ring which fits into the inside of insert 24, and the numeral 54 designates an O-ring retainer.
- a dove tail groove (56) for the O-ring (52) prevents dislodgement due to high flow velocity: The O-ring (52) is first assembled into the insert (24), then the retainer (54) is pushed into the insert and is held into place by cooperating parts (53), (55) of plastic snap fits.
- the dove tail groove (56) is formed between the faces for the insert and retainer (54) as shown in Figures 13, 14a and 14b. Using a standard elastomer O-ring and standard dove tail grove dimensions prevents many problems with using TPE/TPV overmoulded solutions.
- Advantages include improved compression set, reduced sticking in bore, replaceable components, full range of potable water approvals, greater range of temperatures of operation, greater range of fluid resistance, and reduced costs in manufacture.
- the 4 port design with integrated return to boiler allows the valve to seal off the hot water inlet port while keeping the return from the manifold and supply to the manifold open. This allows the valve to seal off the hot water supply from the hot water system while leaving the pump running - therefore no additional pump protection cut off or pressure bypass valve is required when the hot water supply inlet is closed. The valve closes this automatically when the temperature increase above a certain level.
- Indexing flexible projections (72) on the locking ring (36) provide protection against self-opening of the spindle (32) as fluid pressure may cause it to self-open in extreme cases (unwinding of the screw thread).
- Figures 12 and 14a shows how the projections (72) push into corresponding grooves (74) on the outer side of a hollow shaft (76) descending from the underside of temperature control knob (22) resulting in additional force required to unscrew the spindle to the next groove (74) on the hollow shaft (76).
- thermostatic element here a flat diaphragm element, expands and contracts in a known manner with changes in temperature.
- the non-expanding part (60) of the element (28) is screwed onto internal piston (70).
- the expanding part of the element (28) usually a wax (64) contained in a cup (62), is pushed by spring (26) toward the spindle (32).
- Button or disc (31) (of a more durable material than the spindle (32) is provided in a recess in the bottom end of spindle (32) to meet the upper end of internal piston (70) and reduce wear on the bottom end of spindle (32) arising from contact with internal piston (70).
- the button or disc (31) acts as a thrust bearing.
- Piston (30) can adopt a sealing, but not fixed, relationship with the inner face of insert (24) as can be seen in Figures 17, 19 and 21.
- the insert (24) forms a gap which regulates the amount of hot water passing through the valve.
- the piston (32) moves down towards the O-ring (52), and restricts the flow of hot water entering the valve.
- the piston moves all the way down, it creates a seal with the O-ring (52) and completely stops hot water from entering the valve.
- the valve is able to maintain a constant outlet temperature (within a few degrees of tolerance) even when the supply of hot and cooled water pressure and temperature varies.
- the normal set temperature of the valve is set by positioning the spindle (32) up and down.
- the spindle (32) and cap (34) are provided with cooperating threads (33), (35) so that the position of the spindle (32) relative to the cap (34) can be controlled by rotating the spindle (32) relative to the cap (34) by means of temperature control knob (22) which is secured to the upper end of spindle (32) by knob retaining screw (38).
- the thermostatic element (28) and piston (30) will sit at a specific height within the valve body (12) under stable inlet conditions which corresponds to specific temperature. If the spindle (32) is moved down (towards the hot inlet) the stable temperature will be relatively colder, and conversely if the spindle (32) is moved up, the stable temperature will be hotter.
- Figures 17 and 18 depict in cross-section the situation when both hot water inlet (18) and cooled water inlet (16) are open. This is typical of the valve in normal operation. The flow of water is indicated by the arrows.
- FIGs 19 and 20 depict in cross-section the situation when the wax in the thermostatic element (28) has shrunk due to the presence of cooled water.
- the cooled water inlet (16) is shut off by the piston (30) moving to meet with the underside of cap (34) and seal off the opening above the insert (24) for the entry of cooled water.
- the hot water inlet (18) remains open thereby admitting hot water to increase the temperature of the water in interior (1 ) of the valve body (12).
- the cooled water inlet (16) can also be shut off by winding the spindle (32) all the way up.
- Figures 21 and 22 depict in cross-section the situation when the wax in the thermostatic element (28) has expanded due to the presence of hot water.
- the hot water inlet (18) is shut off by the piston moving to seal off the hot water inlet opening in insert (24).
- the cooled water inlet (16) is open thereby admitting cooled water to lower the temperature of the water in the interior (13) of the valve body (12).
- the hot water inlet (18) can also be shut off by winding spindle (32) all the way down.
