Description

Technical Field

[0001] The utility model relates to an electronic valve for flow regulation and closing by coupling a piston with a seating part, the electronic valve having a linear drive of a piston rod, which linear drive displaces the piston by means of an electric system for regulating the flow rate of a liquid passing through the valve.

[0002] The utility model also relates to a liquid regulation and supply device including the above-mentioned electronic valve. Background Art

[0003] In the prior art, it is known to use an electronic valve for regulating the flow rate of a liquid passing through the electronic valve, which electronic valve adopts a flow regulation system by coupling a valve piston and its seating part and a corresponding passage part between the valve piston and the seating part.

[0004] These electronic valves generally have a configuration in which the position of the piston relative to the seating part of the piston is adjusted by the electric movement of a shaft and a piston rod to which the piston is attached, and the piston is moved between a closed position and a fully open position, in which the free passage cross-section between the piston and the seating part is the largest. Between these two positions, as the piston moves on the seating part towards full coupling and closing, the piston reduces the liquid passage cross-section.

[0005] When determining the position of the piston and thus the free passage cross-section for determining the fluid flow rate through the valve between the piston and the seating part, it is understood that different geometries of the piston and the seating part allow: when the electric shaft displaces the piston relative to the seating part, different characteristics in terms of the gradual change of the passage cross-section, and thus also different in terms of the liquid flow rate.

[0006] In this regard, the piston of this type of valve generally has a frustoconical configuration, while the seating part located in the valve body is configured to have at least a cross-section or geometry for receiving a part of the piston, which cross-section or geometry allows defining the end position of the stroke of the displacement of the piston rod to which the piston is attached. The watertight seal of the liquid passing through the opening part between the piston and the seating part is carried out in a conventional manner by an O-ring at a certain point on the forward path of the piston, before or at the end position of the stroke between the piston and the seating part, wherein this watertight seal can be carried out upstream or downstream of the regulation zone.

[0007] This type of valve, due to its configuration in which the piston is displaced by a shaft driven from one end by an electric system, has the disadvantages of potential mechanical vibrations and noise generated by the turbulent fluid when the turbulent fluid passes through the flow throttling zone at an open position within certain ranges between the piston and the seating part in known examples.

[0008] In the prior art, there are systems for introducing the end of the shaft closest to the piston into the valve wall for supporting and guiding this end, where the valve wall is formed by a blind receptacle, and the fluid in contact with the support and guide area is not renewed, such that impurities accumulate in said area. Summary of the Utility Model

[0009] The object of the present utility model is to provide an electronic valve with a linear drive motor, and a liquid regulation and supply device including such an electronic valve, which solves the above-mentioned drawbacks and provides additional advantages to be described below.

[0010] Therefore, in accordance with these objectives, in a first aspect, the present utility model is based on an electronic flow regulating valve having a seating portion and a motor-driven piston. The electronic valve of the present utility model includes a valve body coupled to a drive system, wherein the valve body includes a regulating area having at least one connection portion that connects a liquid inlet to the regulating area within the valve and a connection portion that connects to a liquid outlet of the regulating area within the valve.

[0011] The regulating area includes a flow regulating system formed by at least one displaceable piston that throttles the channel flow when the piston closes on the seating portion, wherein the piston is actuated by the drive system of the electronic valve from a closed position to a fully open position between two extreme positions. In the closed position, the piston is fully closed by being coupled to the seating portion, and in the fully open position, the cross-section of the liquid channel between the piston and the seating portion is the largest. This closing by coupling is achieved by the seal of a joint fixed to the piston and / or by the seal of the geometry of the connection between the piston and the seating portion.

[0012] Advantageously for the present utility model, the piston includes a profile body with a variable geometry and a front guide attachment fixedly attached to the profile body with a variable geometry, where the front guide attachment is a protrusion protruding forward at the downstream end of the piston, and the guide attachment is positioned coaxially with the displaced piston rod of the piston and passes through a guide receptacle.

[0013] Also advantageously for the present utility model, the valve body includes a guide receptacle downstream of the end portion of the valve body, wherein the guide receptacle is formed by at least one channel passing through a guide body, and the geometry of the channel is complementary to the geometry of the guide attachment; both the channel and the guide attachment are configured such that: throughout the process of the guide attachment being displaced between the extreme positions of adjustment by the support and sliding of the guide attachment within the guide receptacle, the guide receptacle and the guide attachment remain coaxial.

[0014] Furthermore and advantageously, the valve body includes a liquid outlet downstream of the regulating zone, the flow rate of which is regulated by the interaction between the piston and the seating portion such that the liquid outlet is achieved by one or more openings arranged at least substantially radially parallel to the displacement axis of the piston.

[0015] This configuration of the present utility model allows for an electronic valve that includes a flow rate regulating system formed by at least one displaceable piston that throttles the channel flow rate when the piston closes on the seating portion, where the piston is actuated by the drive system of the electronic valve according to the requirements of the conditions of the mixture regulated by a conventional control system not described in the present application, and where, when a turbulent liquid flow passes through the fluid throttling zone at certain open position ranges, the displacement of the piston is performed without the vibrations and noises generated by the turbulent liquid flow. This is achieved by, on the one hand, having the piston rod in a conventional manner with a first guiding and supporting portion of the piston rod to the drive system in the proximal region, and on the other hand, advantageously integrating the piston rod into a guiding receptacle in the distal portion relative to the drive system, which provides support at the end of the guiding attachment without an overhanging cross-section, improving the coaxiality of the piston.

[0016] In this configuration, the guiding receptacle arranged to support and guide the piston rod at the distal end of the piston rod relative to the drive system is in a position where it is immersed in the liquid flow from the valve, whereby the fluid in contact with the guiding receptacle is renewed and there is no accumulation of impurities.

[0017] According to a possible embodiment of the present utility model, preferably, the regulating zone includes: one or more openings arranged substantially parallel to the displacement axis of the piston, the one or more openings forming a radial liquid outlet from the regulating zone; and one or more openings arranged substantially transverse to the displacement axis of the piston, the one or more openings forming a liquid outlet for a flow rate substantially parallel to the displacement axis of the piston.

[0018] This configuration increases the axial component of the liquid flow at the outlet of the regulating zone, because the moment of a part of the flow rate remains unchanged, reducing the pressure loss in the valve.

[0019] In this regard, according to a possible embodiment of the above configuration, the liquid outlet of the regulating zone is mostly achieved radially. For a valve configuration with a reduced diameter of the regulating zone, this configuration allows for a larger size of the liquid outlet surface at the side wall of the part containing them, corresponding to the size of the outlet surface at the front wall or transverse wall where the guiding receptacle is located, so as not to require an increase in the outlet diameter of the regulating zone to obtain a larger axial water outlet cross-section when most of the part is occupied by the guiding receptacle.

[0020] According to a possible embodiment of the present utility model, the guiding and accommodating member is preferably formed by a guiding body, and the guiding body, the seating portion of the adjusting area and the liquid outlet opening of the adjusting area are formed as a single piece, wherein the single piece is independent and is connected to the remaining part of the valve body downstream of the adjusting area at the end of the adjusting area, and the single piece is configured such that: the channel opening of the guiding attachment passing through the piston remains coaxial with the displacement of the guiding attachment, and thus in all displacement positions of the piston, the channel opening remains coaxial with the assembly formed by the guiding attachment and the piston and the axis of the piston.

[0021] This embodiment allows for a simple and economical configuration to simplify the production and formation of the overall part of the valve body. Therefore, this configuration is based on two parts, including a first independent part of the guiding body, the seating portion of the adjusting area and the part including the outlet opening, and a second part to which the first part is connected to the drive system.

[0022] According to another possible embodiment of the present utility model, the guiding and accommodating member is formed by a guiding body, the guiding body, the seating portion of the adjusting area and the liquid outlet opening of the adjusting area are formed as a single piece, and the guiding body is further formed as a single piece with the remaining part of the valve body, and the single piece is configured such that: the channel opening of the guiding attachment passing through the piston remains coaxial with the displacement of the guiding attachment, and thus in all displacement positions of the piston, the channel opening remains coaxial with the assembly formed by the guiding attachment and the piston and the piston rod of the piston.

[0023] This alternative configuration allows for a compact solution of the valve body in a single piece, which only needs to be assembled into the engine system.

[0024] According to an alternative embodiment of the present utility model, for the first two configurations of how the different main parts of the valve body are constructed, the guiding and accommodating member is formed by a guiding body, and the guiding body forms a part separated from the part defining the assembly of the seating portion of the adjusting area and the liquid outlet opening of the adjusting area, wherein the part is connected to the part defining the seating portion of the adjusting area, and wherein such assembly is the same piece as the remaining part of the valve body or another independent piece integrally combined with the remaining part of the valve body at the downstream end of the adjusting area, and the assembly is configured such that: the channel opening of the guiding attachment passing through the piston remains coaxial with the displacement of the guiding attachment, and thus in all displacement positions of the piston, the channel opening remains coaxial with the assembly formed by the guiding attachment and the piston and the axis of the piston.

[0025] This configuration, starting from the possibility that the seating part of the regulating zone and the liquid outlet opening of the regulating zone can be a part separate from the rest of the valve body and connected to the rest of the valve body, or starting from the possibility that the seating part and the liquid outlet opening are integrated with the valve body into a single piece, introduces the configuration of the receiving part body formed by separate parts, which allows better tribology of the material, allows the selection of a specific material with better performance for the body, without having to associate the body with a larger overall part and different design requirements.

[0026] Preferably, although other configurations are alternative solutions, the guiding body is formed by a ring, which is configured to have an opening complementary to the geometry of the guiding attachment of the piston, and the ring allows the guiding attachment to be slidably supported through the ring. At the same time, the annular geometry of the ring allows the ring to be incorporated or connected in the part including the liquid outlet opening and the seating part of the regulating zone. As previously mentioned, other configurations are also possible, and a cylindrical body or a guiding body compatible with the displacement of the piston guiding attachment guided by them should be understood as equivalent to this ring configuration.

[0027] Regarding the position of the guiding body, the guiding body is positioned flush with the end downstream of the opening, so that no liquid accumulation tank is generated in the liquid outlet zone downstream of the liquid outlet. This avoids the accumulation of particles at the base that may occur in the prior art configurations using blind holes.

[0028] These existing embodiments of the valve body allow for an assembly configuration in several parts according to the described final function and make its manufacturing feasible using different techniques such as machining and thermoplastic injection, etc., thus reducing the production and assembly costs of the components. They also allow the selection of materials for each component, which ensures good tribological performance between the frictional torques under the operating conditions of the valve, minimizing the frictional force and wear during the service life of the valve.

[0029] Also optionally but preferably, according to the above embodiment, the piston guiding attachment is formed by a part separate from the profile body with variable geometry of the piston, and the guiding attachment is integrally connected to the profile body with variable geometry of the piston, so that the assembly of the piston and the guiding attachment remains coaxial with the displacement axis.

[0030] This possibility of making the piston independent of the guiding attachment but integrally connected to the guiding attachment allows for the most effective selection of materials in terms of the cost and performance of its function.

[0031] Thus, according to another possible embodiment of the present utility model, the guiding attachment mainly comprises stainless steel, while the piston coupled thereto mainly comprises plastic material. This allows a configuration that reduces costs but has the characteristics of the guiding attachment, which allows for reliable support and sliding function in the guiding receptacle. In these cases, the majority of the components must be understood as the majority proportion of the weight of the elements themselves.

[0032] As an alternative to the above embodiment, the guiding attachment is constituted by the same component as the geometrically variable profile body of the piston, wherein the components in the single piece of the piston and the guiding attachment are coaxial with the displacement axis of the components. This configuration allows for greater assembly simplicity and fewer variations in installation tolerances.

[0033] According to a possible embodiment of the present utility model applicable to any of the previous main configurations, the geometrically variable profile body of the piston has a conical geometry.

[0034] As an alternative to the above embodiment, the geometrically variable profile body of the piston has an elliptical geometry.

[0035] Also as an alternative to the previous two embodiments, the geometrically variable profile body of the piston consists of straight and / or curved sections without defining a specific geometric profile.

[0036] These embodiments are based on the geometric configuration of the geometrically variable profile, allowing the selection of a flow curve pattern for the piston stroke relative to the geometry of the same seating portion.

[0037] According to another possible embodiment of the present utility model, complementary to any of the previous embodiments, the geometrically variable profile body of the piston is configured such that the outer surface has a helical groove, and when the position of the piston relative to the seating portion and its position on the coupling surface of the seating portion allow liquid to flow towards the liquid outlet of the valve body, the helical groove is used to allow the liquid to pass through the helical groove.

[0038] This configuration of the outer surface of the piston body with the helical groove generates a pressure loss in the liquid flow through the groove, which is in addition to the pressure loss generated in the variable channel portion of the piston. Therefore, for a given piston size and compared with a piston body having a smooth outer surface without grooves, this additional pressure loss allows for improved flow regulation at very low flow rates that can be adjusted lower than those without the above characteristics.

[0039] For the above purposes, regarding the second aspect, the present utility model is based on a liquid regulation and supply device, wherein the device includes at least one electronic valve with a linear drive motor, the motor having a control system that controls the actuation of the regulation system of at least one electronic valve.

[0040] Advantageously, at least one electronic valve is configured to be the electronic valve shown in any of the embodiments shown in the first aspect of the present utility model.

[0041] Such a configuration of the liquid regulating and supplying device allows for the advantages of simplicity, compactness, configuration, effectiveness, operation, and cost of the electronic valve described in the first aspect of the embodiments of the present utility model.

[0042] According to a preferred embodiment of the present utility model, the liquid regulating and supplying device is configured as a mixing tank, and the mixing tank has an electronic valve as described in the embodiments of the first aspect of the present utility model for each liquid inlet of the liquid mixing tank.

[0043] According to another possible embodiment of the present utility model, the liquid regulating and supplying device is configured as an electronic faucet, and the electronic faucet has an electronic valve as described in the embodiments of the first aspect of the present utility model for each liquid inlet of the electronic liquid regulating and supplying faucet.

Detailed implementation mode

[0054] For the convenience of understanding the present disclosure, the following describes possible implementation modes of the technical solutions of the present utility model to facilitate a full understanding of the present disclosure.

[0055] However, it should be noted that the present utility model can be implemented in a different manner from that described in this application without restricting the specific protection scope of these implementation modes, because those skilled in the art can make similar changes without departing from the scope of the present disclosure.

[0056] In the first preferred implementation mode of the present utility model, as well as as shown in Figure 1a and Figure 1b and Figure 2 shown, the electronic valve 10 is formed by a valve body 11, and the valve body 11 is coupled to a drive system 12, and the drive system 12 displaces a piston rod 121 attached to a piston 13. In this preferred implementation mode, the drive system 12 is a stepper motor, and the stepper motor allows the displacement of the piston rod 121 to be adjusted in an accurate manner, thereby adjusting the position of the piston 13.

[0057] The valve body 11 is formed by two main parts. The first part 111 includes:

[0058] - a seating portion 14 of the regulating area 15 for liquid flow, where the piston 13 and its corresponding seal 131 couple and enclose the regulating area 15 and the seating portion 14;

[0059] - a liquid outlet opening 16 of the regulating area 15; and

[0060] - a guiding receptacle 17 for piston displacement 13.

[0061] The valve body 11 includes a second part 112, and the second part includes devices of the drive system 12 and a coupling area and a receptacle for the piston rod 121 to which the piston 13 is attached. The two parts 111, 112 are coupled to obtain a valve body assembly 11 having two components 111, 112.

[0062] As an alternative to the valve body configuration, as Figure 7 and Figure 8 shown in, there is a valve 40 in which the valve body 41 has a first part 411 that does not include a guiding receptacle 47 for the movement of the piston 43, the guiding receptacle 47 being an independent part that is specifically selected from different materials and has suitable and specific tribological properties for its function, different from other parts of the first part 411 of the valve body 41.

[0063] For additional alternatives not shown in the figures of this valve body configuration, the components and assemblies of the first and second parts of the valve body can be formed in a single part.

[0064] Continuing with the first preferred embodiment, the piston 13 is moved along an axial movement path by a drive system 12 from a maximum channel flow regulation position to a closed position. In the maximum channel flow regulation position, the liquid channel cross-section between the outer surface 132 of the piston and the seating portion 14 of the valve body 11 is the largest. In the closed position, the seal 131 of the piston closes over the area of the seating portion 14. Flow regulation occurs in the regulation zone 15, where the piston body 13 throttles the liquid flow through the free cross-section between the piston 13 and the seating portion 14 more or less according to the position of the piston body 13 relative to the seating portion 14. The actuation of the drive system 12 is controlled by a control system external to the drive system 12 itself, which modifies the displacement of the piston rod 121 according to the liquid flow rate through the valve 10 required for specific needs.

[0065] In such a regulation system, the geometry of the piston 13 and the geometry of the seating portion 14 define a characteristic pattern of each geometry of the liquid channel cross-section change, thus defining the change in the channel flow rate. In this embodiment, the geometry of the piston 13 has a conical shape with different inclination angle portions of the generatrix of the piston body 13. When the piston 13 moves relative to the seating portion 14, other geometrically variable profiles of the piston are also feasible, such as an elliptical profile, or a profile formed by straight and / or curved portions and not defining a specific geometry, as long as there is a change in the geometry of the piston profile or at least a change in the free channel cross-section between the piston body 13 and the seating portion 14.

[0066] The piston 13 includes a front guide attachment 133 integrally combined with the body of the piston 13, and the front guide attachment 133 is coaxial with the displaced piston rod 121 of the piston 13. In the present embodiment, the guide attachment 133 and the body of the piston 13 form a single piece, and the guide attachment 133 is inserted for the support and guidance of the guide attachment 133 in the guide receptacle 17 to maintain the coaxial movement of the piston 13 and the piston rod 121 of the piston 13 at any point of the displacement of the piston 13, avoiding the vibration and noise existing in the prior art. In the present embodiment, the guide receptacle 17 is formed by an annular body, but there may be other geometries complementary to the guide attachment, having a channel 171 passing through the guide attachment, wherein the geometry of the channel is complementary to the geometry of the guide attachment 133, and both the channel 171 and the guide attachment 133 are configured such that, as described above, through the support and sliding of the guide attachment 133 in the guide receptacle 17, during the displacement of the guide attachment between the extreme adjustment positions, the guide receptacle and the guide attachment remain coaxial.

[0067] As Figure 5 and Figure 6 shown in, as an alternative configuration of the guide attachment 333, the guide attachment 333 is a component of the piston 33 independent of the valve 30, wherein the material of the guide attachment 333 is different from the material of the piston body 33, so that the characteristics of the guide attachment 333 allow for more effective operation considering the friction with the guide receptacle 37. In this embodiment, it can be understood that the guide attachment 333 mainly includes stainless steel, while the piston 33 coupled to the guide attachment 333 mainly includes a plastic material, thereby enabling the cost of the components to be rationalized without the need for improved tribological properties.

[0068] The valve 10 has a liquid inlet 18 leading to the adjustment zone 15, wherein the flow rate of the liquid is throttled in the adjustment zone 15 by the position of the piston 13 relative to the seating portion 14, and the valve 10 has an outlet 19 for the liquid with the adjusted flow rate.

[0069] The liquid outlet 19 from the adjustment zone 15 is made radially, that is, through an opening radially arranged in the side wall 151, substantially parallel to the displacement axis of the piston 13.

[0070] This configuration prevents particles from accumulating in this region of the guide receptacles 17, 37 of the attachments 133, 333, because the guide receptacles 17, 37 are not arranged as blind holes, but as through openings adjacent to the liquid outlet zone 19 of the adjustment zone, thereby minimizing the possibility of any particle accumulation that the liquid may contain.

[0071] According to an alternative embodiment of the arrangement of the opening of the liquid outlet 19 of the regulating zone, a part of the opening must be arranged perpendicular to the axial configuration of the axis 12 of piston displacement, and part maintains the coaxial direction of the liquid passing through the regulating zone 15. This distribution of the opening of the liquid outlet 19 of the regulating zone 15 is configured such that the outlet surface is mostly located on the side wall forming the radial outlet.

[0072] As an alternative to the configuration of pistons 23, 33, as Figures 3 to 6 shown, the outer surfaces 232, 332 of pistons 23, 33 have helical grooves for the passage of liquid through the helical grooves, increasing the pressure drop of the liquid flow and allowing for more effective regulation in the low flow rate range.

[0073] As Figure 9a and Figure 9b shown, valves 10, 20, 30, 40 are integrated in a liquid regulating and supply device 100 of mixer box type, which liquid regulating and supply device includes electronic valves, such as the electronic valves as described in the above embodiments for each liquid inlet F, C leading to the mixer box, supplying a regulated flow rate in each liquid inlet F, C for mixing in the area M for the mixer box.

[0074] As an alternative to the above embodiments, the liquid regulating and supply device is configured as a device of electronic faucet type, which device includes valves 10, 20, 30, 40 for each liquid inlet leading to the faucet, not shown in the figures.

[0075] Although reference has been made to several specific embodiments of the present utility model, it will be apparent to those skilled in the art that the electronic valve with a linear drive motor and the water supply device including the electronic valve are susceptible to various changes and modifications, and all the above details can be replaced by other technically equivalent technical details without reducing the scope of protection defined by the appended claims.
