Description

Turbine-type flow inlet valve Technical Field

[0001] This application relates to the field of valve technology, and in particular to a turbine-type flow inlet valve. Background Technology

[0002] The flow sensor of a gas-fired wall-hung boiler is used in the boiler's bathroom system to sense the bathroom demand and size. When using a turbine-type flow sensor for a wall-hung boiler, different flow-limiting rings need to be configured for different power ratings.

[0003] In related technologies, the flow-limiting ring is installed at the front end of the turbine-type flow sensor, and the water inlet channel is directly opposite the flow sensor. The water flow directly impacts the turbine-type flow sensor, resulting in low detection accuracy of the flow sensor. Summary of the Invention

[0004] This application provides a turbine-type flow inlet valve, which solves the technical problem that the flow sensor's detection accuracy is low due to the direct impact of water flow on the turbine-type flow sensor.

[0005] To achieve the above objectives, the main technical solutions adopted in this application include:

[0006] This application provides a turbine-type flow inlet valve, which includes a valve body, a flow component, and a flow limiting ring. The valve body has an inlet channel, a flow stabilizing chamber, and an outlet channel connected in sequence. The flow component is disposed in the outlet channel and is used to measure the flow rate of the outlet channel. The flow limiting ring is disposed in the inlet channel. The flow stabilizing chamber has a first opening and a second opening. The first opening is connected to the inlet channel, and the second opening is connected to the outlet channel. When the turbine-type flow inlet valve transmits the medium, the first opening is connected to the second opening through a bend in the flow channel.

[0007] The turbine-type flow inlet valve proposed in this application has a first opening connected to a second opening through a bend in the flow channel when the turbine-type flow inlet valve transmits the medium. This avoids the water flow directly impacting the flow component after passing through the flow limiting ring. The bend in the flow channel can buffer and stabilize the water flow, reduce the impact force on the flow component, and ensure the accuracy and consistency of the flow measurement of the water flow of the flow component.

[0008] Optionally, the flow stabilizing chamber is cylindrical in shape and has a first peripheral wall and a first bottom wall. The first bottom wall is located at one end of the first peripheral wall in the axial direction, a first opening is located on the first peripheral wall, and a second opening is located on the first bottom wall.

[0009] The first opening is located on the first peripheral wall, and the second opening is located on the first bottom wall. This avoids the medium from directly impacting the flow component after entering the flow stabilization chamber through the first opening, thus improving the measurement accuracy of the turbine-type flow inlet valve.

[0010] Optionally, along the axial direction of the water inlet channel, the cross-sectional area of ​​the flow stabilizing chamber is larger than the cross-sectional area of ​​the water inlet channel.

[0011] The larger cross-sectional area of ​​the flow stabilizing chamber can reduce the flow velocity of the water, reduce the pressure of the water in the flow stabilizing chamber, and enhance the flow stabilizing effect of the flow stabilizing chamber.

[0012] Optionally, the water outlet channel includes a first flow channel and a turbine chamber, the flow component is disposed in the turbine chamber, along the axial direction of the first flow channel, one end of the first flow channel is connected to a second opening, the other end of the first flow channel is connected to the turbine chamber, and the cross-sectional area of ​​the flow stabilizing chamber is larger than the cross-sectional area of ​​the first flow channel.

[0013] Along the axial direction of the first flow channel, the cross-sectional area of ​​the flow stabilizing chamber is larger than that of the first flow channel. This can prevent the water flow from stratifying in the first flow channel and avoid the occurrence of different flow velocities in different areas of the first flow channel.

[0014] Optionally, along the axial direction of the first flow channel, the cross-sectional area of ​​the first flow channel is smaller than the cross-sectional area of ​​the turbine chamber.

[0015] The cross-sectional area of ​​the first flow channel is smaller than that of the turbine chamber. This reduces turbulence in the water flow within the turbine chamber, making the flow component rotate more evenly and improving the detection accuracy of the flow component.

[0016] Optionally, the flow assembly has a turbine structure located in a turbine chamber; the first flow channel has a first axis, the turbine structure has a second axis, the extension direction of the first axis is perpendicular to the extension direction of the second axis, and the first axis and the second axis do not intersect along the axial direction of the first flow channel.

[0017] The first axis and the second axis do not intersect, so the water flow will not rush towards the center of the turbine structure in the direction of the first flow channel. The water flow impact direction in the first flow channel is set at intervals from the center of the turbine structure, so that the water flow can exert a force on the turbine blades and drive the turbine blades to rotate, preventing the turbine structure from not rotating.

[0018] Optionally, the water outlet channel also includes a second flow channel, one end of which is connected to the turbine chamber, and the other end of which is connected to the drain port of the turbine flow inlet valve.

[0019] The second flow channel provides a passage between the turbine chamber and the drain port of the turbine flow inlet valve, making it easier to connect the drain port of the turbine flow inlet valve to other components and expanding the application range of the turbine flow inlet valve.

[0020] Optionally, the drain port of the turbine flow inlet valve is oriented to intersect the axis of the second flow channel.

[0021] This allows for the reversal of the water flow direction, making it easier for the turbine-type flow inlet valve and other components to change direction at corners or in confined spaces.

[0022] Optionally, the turbine-type flow inlet valve also includes a filter screen, which is disposed in the inlet channel along the axial direction of the inlet channel, on the side of the flow-limiting ring away from the flow-stabilizing chamber.

[0023] The filter screen can prevent impurities from entering the flow restrictor ring and flow components, reduce the chance of damage to the flow restrictor ring and flow components, and improve the stability and reliability of the turbine flow inlet valve.

[0024] Optionally, the turbine-type flow inlet valve also includes a first connector, a flow-limiting ring and a filter screen, both of which are located on the first connector, which is detachably located on the valve body.

[0025] The first connector is detachably mounted on the valve body, which improves the efficiency of maintenance or replacement of the filter screen and flow restrictor ring. Attached Figure Description

[0045] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

The terms "first," "second," etc., in the description, claims, or accompanying drawings of this application are used to distinguish different objects, not to describe a specific order or hierarchy.

[0047] In this application, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.

[0048] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "attachment" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0049] In this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, in this application, the character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0050] In this application, "multiple" refers to two or more (including two), and similarly, "multiple groups" refers to two or more (including two), and "multiple pieces" refers to two or more (including two).

[0051] The flow sensor in a gas-fired wall-hung boiler is a core component of its bathroom system, primarily used to sense the user's hot water demand and water flow rate. When the user turns on the hot water tap, water flows through the flow sensor, causing an internal turbine-like impeller to rotate. A Hall effect sensor linked to the impeller converts the impeller's rotational speed into an electrical signal, which is then fed back to the boiler's control system. Since the water flow rate directly affects the impeller's rotational speed, different flow rates correspond to feedback signals of varying intensity and frequency. Based on this, the boiler precisely adjusts the gas combustion power and hot water output to provide on-demand heating.

[0052] When using a turbine-type flow sensor for a wall-hung boiler, different flow-limiting rings are required for different power ratings. In related technologies, the flow-limiting ring is installed at the front end of the turbine-type flow sensor, with the water inlet channel directly facing the flow sensor. This causes the water flow to directly impact the turbine-type flow sensor, resulting in low detection accuracy.

[0053] In view of this, this application proposes a turbine-type flow inlet valve, which includes a valve body, a flow component, and a flow limiting ring. The valve body has an inlet channel, a flow stabilizing chamber, and an outlet channel connected in sequence. The flow component is disposed in the outlet channel and is used to measure the flow rate of the outlet channel. The flow limiting ring is disposed in the inlet channel. The flow stabilizing chamber includes a first opening and a second opening. The first opening is connected to the inlet channel, and the second opening is connected to the outlet channel. When the turbine-type flow inlet valve transmits the medium, the first opening is connected to the second opening through a bend in the flow channel.

[0054] In the above scheme, when the turbine-type flow inlet valve transmits the medium, the first opening is connected to the second opening through a bend in the flow channel. This can prevent the water flow from directly impacting the flow component after passing through the flow limiting ring. The bend in the channel can buffer and stabilize the water flow, reduce the impact force on the flow component, and ensure the accuracy and consistency of the flow measurement of the water flow of the flow component.

[0055] In this embodiment of the application, the axial direction of the first flow channel and the axial direction of the second flow channel can be parallel.

[0056] The turbine-type flow inlet valve disclosed in this application can be used not only for water flow detection, but also for testing the flow of other fluids such as liquid methanol.

[0057] For ease of explanation, the following embodiments will be described using a turbine-type flow inlet valve according to an embodiment of this application as an example.

[0058] Figure 1 is a schematic diagram of the turbine-type flow inlet valve provided in the embodiment of this application; Figure 2 is a front view of Figure 1; Figure 3 is a cross-sectional view of Figure 2 in the AA direction; Figure 4 is a top view of Figure 1; Figure 5 is a cross-sectional view of Figure 4 in the BB direction.

[0059] Referring to Figures 1 to 5, in this embodiment, the turbine-type flow inlet valve 1000 includes a valve body 100, a flow component 140, and a flow-limiting ring 150. The valve body 100 has an inlet channel 110, a flow-stabilizing chamber 120, and an outlet channel 130 connected in sequence. The flow component 140 is disposed in the outlet channel 130 and is used to measure the flow rate of the outlet channel 130. The flow-limiting ring 150 is disposed in the inlet channel 110. The flow-stabilizing chamber 120 has a first opening 121 and a second opening 122. The first opening 121 is connected to the inlet channel 110, and the second opening 122 is connected to the outlet channel 130. When the turbine-type flow inlet valve 1000 transmits the medium, the first opening 121 is connected to the second opening 122 through a bend in the flow channel.

[0060] Water can flow from the inlet channel 110 to the flow stabilizing chamber 120, and from the flow stabilizing chamber 120 to the outlet channel 130. The flow component 140 can be a turbine-type flow component, where the water flow impacts and rotates the turbine. The flow component 140 measures the flow rate in the outlet channel 130. A flow-limiting ring 150 is used to limit the maximum inlet flow rate. The flow-limiting ring 150 can limit the maximum inlet flow rate of the inlet channel 110 per unit time, avoiding excessive instantaneous flow. The water flows from the inlet channel 110 to the first opening 121 of the flow stabilizing chamber 120, and then from the second opening 122 of the flow stabilizing chamber 120 to the outlet channel 130. The flow stabilizing chamber 120 can stabilize and buffer the water flow, preventing the water flow limited by the flow-limiting ring 150 from directly impacting the flow component 140, thus reducing the impact force of the water flow on the flow component 140.

[0061] For example, water flows into the flow stabilizing chamber 120 through the first opening 121, flows through the bend channel, and then flows out of the flow stabilizing chamber 120 through the second opening 122. The orientation of the first opening 121 can intersect with the orientation of the second opening 122. The flow direction of the water changes after flowing through the bend channel, which can buffer the water flow, reduce the impact force of the water flow on the flow component 140, and improve the detection accuracy of the flow component 140.

[0062] When the turbine-type flow inlet valve 1000 transmits the medium, the fluid medium flows from the first opening 121 through the bend channel to the second opening 122. The flow direction of the fluid medium changes within the bend channel, reducing the impact force of the fluid medium on the flow assembly 140.

[0063] In addition, different models of gas wall-hung boilers require different models and specifications of flow-limiting rings 150. Different flow-limiting rings 150 result in different impact forces on the water flow after flow restriction. The flow stabilizing chamber 120 is located between the flow-limiting ring 150 and the flow component 140. This allows the turbine flow inlet valve 1000 to be compatible with a variety of flow-limiting rings 150, thereby enabling the turbine flow inlet valve 1000 to be adapted to different models of gas wall-hung boilers and expanding the applicability of the turbine flow inlet valve 1000.

[0064] Please refer to Figures 1 to 5. In this embodiment, the flow stabilizing chamber 120 is cylindrical. The flow stabilizing chamber 120 has a first peripheral wall 124 and a first bottom wall 123. The first bottom wall 123 is disposed at one end of the first peripheral wall 124 in the axial direction. The first opening 121 is disposed on the first peripheral wall 124, and the second opening 122 is disposed on the first bottom wall 123.

[0065] In this way, the medium enters the flow stabilizing chamber 120 through the first opening 121 and then impacts the first peripheral wall 124 of the flow stabilizing chamber 120. The direction and magnitude of the medium's flow velocity change, and then it flows out through the second opening 122 provided on the first bottom wall 123 and flows to the flow assembly 140. This avoids the medium directly impacting the flow assembly 140 after entering the flow stabilizing chamber 120 through the first opening 121, thus improving the measurement accuracy of the turbine-type flow inlet valve 1000.

[0066] In some embodiments, the orientation of the first opening 121 is perpendicular to the orientation of the second opening 122.

[0067] The orientation of the first opening 121 is perpendicular to the orientation of the second opening 122 at a 90° angle, and the axial direction X of the water inlet channel is perpendicular to the axial direction of the water outlet channel 130 at a 90° angle. For example, water can enter the flow stabilization chamber 120 from the first opening 121. The water can impact the inner wall of the flow stabilization chamber 120. After impacting the inner wall of the flow stabilization chamber 120, the water is dispersed, the flow velocity decreases, and the flow direction changes. The impact force of the water flowing from the second opening 122 to the flow component 140 is reduced, and the water can flow more evenly to the flow component 140, improving the measurement accuracy of the flow component 140.

[0068] In addition, the orientation of the first opening 121 is perpendicular to the orientation of the second opening 122, which enables the turbine-type flow inlet valve 1000 to switch between horizontal water inlet and vertical water outlet within a limited space, eliminating the need for additional elbow pipes and saving manufacturing costs.

[0069] Please refer to Figures 1 to 5. In this embodiment, along the axial direction X of the water inlet channel, the cross-sectional area of ​​the flow stabilizing chamber 120 is greater than the cross-sectional area of ​​the water inlet channel 110.

[0070] Water flows from the inlet channel 110 to the flow stabilizing chamber 120. The larger cross-sectional area of ​​the flow stabilizing chamber 120 can reduce the flow velocity of the water. The pressure of the water in the flow stabilizing chamber 120 is reduced, which enhances the flow stabilizing effect of the flow stabilizing chamber 120, reduces the impact force of the water flow on the flow component 140, and improves the detection accuracy of the flow component 140.

[0071] Please refer to Figures 1 to 5. In this embodiment, the water outlet channel 130 includes a first flow channel 131 and a turbine chamber 132. The flow component 140 is disposed in the turbine chamber 132. Along the axial direction Y of the first flow channel, one end of the first flow channel 131 is connected to the second opening 122, and the other end of the first flow channel 131 is connected to the turbine chamber 132. The cross-sectional area of ​​the flow stabilizing chamber 120 is larger than the cross-sectional area of ​​the first flow channel 131.

[0072] Water flows from the steady flow chamber 120 to the first flow channel 131, and then from the first flow channel 131 to the turbine chamber 132. The flow component 140 is disposed in the turbine chamber 132 and measures the flow rate of the water flowing from the first flow channel 131 to the turbine chamber 132.

[0073] Along the axial direction Y of the first flow channel, the cross-sectional area of ​​the flow stabilizing chamber 120 is larger than that of the first flow channel 131. This can also prevent the water flow from stratifying within the first flow channel 131 and avoid the occurrence of different flow velocities in different areas of the first flow channel 131.

[0074] Moreover, the cross-sectional area of ​​the flow stabilizing chamber 120 is larger than that of the first flow channel 131, which can increase the flow velocity of the water in the first flow channel 131 and increase the impact force of the water in the first flow channel 131, thereby making it easier to rotate the flow component 140.

[0075] Referring to Figures 1 to 5, in this embodiment, the cross-sectional area of ​​the first flow channel 131 along the axial direction Y is smaller than the cross-sectional area of ​​the turbine chamber 132.

[0076] Water flows from the first flow channel 131 to the turbine chamber 132. The turbine chamber 132 has a larger cross-sectional area and can absorb the kinetic energy of the water flow, reducing turbulence in the water flow and making the flow component 140 rotate more evenly, thereby improving the detection accuracy of the flow component 140.

[0077] Referring to Figures 1 to 5, in this embodiment, the flow assembly 140 has a turbine structure 141 located in the turbine chamber 132; the first flow channel 131 has a first axis 131A, and the turbine structure 141 has a second axis 141A. The extension direction of the first axis 131A is perpendicular to the extension direction of the second axis 141A. Along the axial direction Y of the first flow channel, the first axis 131A and the second axis 141A do not intersect.

[0078] The turbine structure 141 has turbine blades. Water flow impacts the turbine blades, causing them to rotate. Combined with components such as Hall effect sensors, this enables flow rate detection. For example, the turbine blades can rotate around a second axis 141A along the axial direction Y of the first flow channel. The first axis 131A and the second axis 141A do not intersect. That is, when water flows from the first flow channel 131 to the turbine chamber 132, the water flow does not directly impact the second axis 141A of the turbine structure 141. Furthermore, the water flow does not rush towards the center position of the turbine structure 141 in the extension direction of the first flow channel 131. The water flow impact direction in the first flow channel 131 is spaced apart from the center position of the turbine structure 141. This allows the water flow to exert a force on the turbine blades, driving them to rotate and preventing the turbine structure 141 from not rotating.

[0079] Referring to Figure 5, water flows from the first flow channel 131 to the turbine chamber 132, impacting the turbine blades of the turbine structure 141. The turbine structure 141 rotates clockwise as shown in the figure.

[0080] Please refer to Figures 1 to 5. In this embodiment, the water outlet channel 130 further includes a second flow channel 133. One end of the second flow channel 133 is connected to the turbine chamber 132, and the other end of the second flow channel 133 is connected to the drain port 170 of the turbine flow inlet valve 1000.

[0081] Water flows from the inlet 160 of the turbine flow inlet valve 1000 into the inlet channel 110, then flows from the inlet channel 110 to the flow stabilizing chamber 120, from the flow stabilizing chamber 120 to the first flow channel 131, from the first flow channel 131 to the turbine chamber 132, from the turbine chamber 132 to the second flow channel 133, and from the second flow channel 133 to the outlet 170 of the turbine flow inlet valve 1000.

[0082] The second flow channel 133 provides a passage between the turbine chamber 132 and the drain port 170 of the turbine flow inlet valve 1000, making it easier to connect the drain port 170 of the turbine flow inlet valve 1000 to other components and expanding the applicability of the turbine flow inlet valve 1000.

[0083] Please refer to Figures 1 to 5. In this embodiment, the orientation of the drain port 170 of the turbine flow inlet valve 1000 intersects with the axial direction of the second flow channel 133.

[0084] Water flows from the second flow channel 133 to the drain port 170 of the turbine flow inlet valve 1000, and then from the drain port 170 of the turbine flow inlet valve 1000 to other components. The orientation of the drain port 170 of the turbine flow inlet valve 1000 intersects with the axis of the second flow channel 133, which enables the flow direction of the water to be changed, making it easier for the turbine flow inlet valve 1000 and other components to be changed at corners or in narrow spaces.

[0085] Referring to Figures 1 to 5, in this embodiment, the turbine-type flow inlet valve 1000 further includes a filter screen 180, which is disposed in the inlet channel 110. Along the axial direction X of the inlet channel, the filter screen 180 is located on the side of the flow limiting ring 150 away from the flow stabilizing chamber 120.

[0086] The filter screen 180 can filter impurities in the water flow. For example, the filter screen 180 can intercept impurities such as mud and sand in the water flow, prevent impurities from entering the flow limiting ring 150 and the flow component 140, reduce the probability of the flow limiting ring 150 and the flow component 140 being damaged, and improve the stability and reliability of the turbine flow inlet valve 1000.

[0087] In some embodiments, the filter 180 may be configured as a metal mesh or a perforated plate structure.

[0088] Referring to Figures 1 to 5, in this embodiment, the turbine-type flow inlet valve 1000 further includes a first connector, and the flow limiting ring 150 and the filter screen 180 are both disposed on the first connector. The first connector is detachably disposed on the valve body 100.

[0089] The first connector is detachably provided on the valve body 100. For example, the first connector can be detachably connected to the valve body 100 by means of threads, snaps, etc. A sealing ring can be provided between the first connector and the valve body 100 to improve the sealing performance between the first connector and the valve body 100 and reduce water leakage.

[0090] The water inlet channel 110 can be located inside the first connector. The flow-limiting ring 150 and the filter screen 180 are located in the first connector. This way, when the flow-limiting ring 150 needs to be replaced with a different model or requires maintenance and replacement, the first connector can be removed to replace the flow-limiting ring 150, improving maintenance and replacement efficiency. When the filter screen 180 needs maintenance or replacement due to prolonged use, the first connector can be removed to replace or maintain the filter screen 180, improving maintenance or replacement efficiency.
