Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a connecting mechanism for valves and a valve assembly. Background Art

[0002] In existing valve technology, accurate monitoring of valve opening and closing status is crucial for preventing leakage. Therefore, the use of valve opening and closing sensors has become indispensable. These sensors provide real-time feedback on the valve's opening and closing status, helping operators to promptly understand the valve's operating status. This effectively prevents safety issues caused by accidental valve closure and leaks caused by partially closed or opened valves.

[0003] However, a significant technical challenge in practical applications lies in the often compact installation environments of valves. Due to space constraints, traditional position sensors can be difficult to locate. This not only increases installation complexity but can also negatively impact sensor performance due to improper placement.

[0004] Furthermore, even if the sensor can be installed in a compact space, it is susceptible to collisions with surrounding components or structures during operation. Such collisions can not only damage or fail the sensor but can also adversely affect the valve itself and other adjacent components. Therefore, how to properly install the sensor in a compact installation environment to prevent it from interfering with the operator's valve opening and closing or causing accidental impacts has become a pressing issue in existing technology.

[0037] As mentioned in the background, in environments where valve installation space is tight, the use of position sensors is crucial for ensuring accurate monitoring of valve opening and closing conditions. However, due to space constraints and the sensor's vulnerability to collision with surrounding components, effectively installing and protecting these sensors presents a significant technical challenge.

[0038] In order to solve the above technical problems, an embodiment of the present application provides a connecting mechanism and a valve assembly for a valve, wherein the connecting mechanism includes: at least one connecting unit connected in sequence, wherein each connecting unit includes a first surface and a second surface having a non-zero angle, the first surface of the previous connecting unit is detachably connected to the second surface of the next connecting unit, and the extension direction of the connecting mechanism changes with the deflection angle of the first surface of the previous connecting unit relative to the second surface of the next connecting unit; a first fixing portion, used to fix the first connecting unit of at least one connecting unit to the valve; a second fixing portion, connected to the last connecting unit of at least one connecting unit, and the second fixing portion is used to position a sensor.

[0039] Using the technical solution of the embodiment of the present application, the connection mechanism is composed of a plurality of detachable and deflectable connection units, so that the extension direction of the connection mechanism can be flexibly adjusted according to the specific space in which the valve is located. This design greatly improves the flexibility and adaptability during installation, allowing the sensor to find a suitable installation position even in a compact space. Due to the deflection connection between the connection units, the sensor can move away from potential collision points through a tortuous path, thereby avoiding direct contact with surrounding components. This not only protects the sensor from damage, but also reduces the risk of performance degradation or failure due to collision.

[0040] In order to make the above-mentioned objects, features and beneficial effects of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0041] Figure 1 It is a structural schematic diagram of a valve assembly 100 according to an embodiment of the present utility model.

[0042] refer to Figure 1 and Figure 2 The valve assembly 100 includes: a valve 20; a connecting mechanism 10, fixed to the valve 20 through the first fixing part 2; a sensor 30, positioned on the second fixing part 3, the sensor 30 moves synchronously with the valve 20 via the connecting mechanism 10 to collect the opening and closing degree of the valve 20, and the extension direction of the connecting mechanism 10 is determined according to the space where the valve 20 is located.

[0043] Specifically, the valve 20 can be applied in a variety of fields. For example, in the petroleum, chemical, and power industries, the valve 20 is used to control and regulate the flow of fluid media to ensure the smooth operation of production processes. Another example is the natural gas industry, where the valve 20 can be used in various aspects of natural gas collection, processing, storage, transportation, and use. For example, during the natural gas collection phase, the valve 20 can be used to control gas wells, water injection during drilling processes, and control gas production and pressure.

[0044] Furthermore, the sensor 30 can monitor the degree of opening and closing of the valve 20. The sensor 30 is precisely positioned on the second fixing portion 3 of the connecting mechanism 10. Because the connecting mechanism 10 and the valve 20 move synchronously, the sensor 30 also moves with the opening and closing of the valve. This allows the sensor 30 to collect the degree of opening and closing of the valve 20 in real time and provide this information to the operator, helping them to promptly understand the valve's operating status.

[0045] In some embodiments, the sensor 30 can detect the degree of opening or closing of the valve 20 based on the principle of geomagnetic induction. For example, the sensor 30 can use changes in the geomagnetic field to detect the position or motion of an object. In the valve assembly 100, when the valve 20 opens or closes, it drives the connecting mechanism 10 to move, which in turn drives the sensor 30 to move. During this process, the sensor 30 can capture subtle changes in the surrounding magnetic field and convert them into electrical signals for transmission and processing.

[0046] Furthermore, in the valve assembly 100, the sensor 30 can be mounted on the second fixing portion 3 of the connecting mechanism 10 to maintain synchronous movement with the valve 20. Because the sensor 30 utilizes the principle of geomagnetic induction and has the characteristic of non-contact measurement, the sensor 30 is not affected by mechanical friction or collision during the movement of the valve 20, thereby improving the accuracy and stability of the measurement.

[0047] Furthermore, one end of the connecting mechanism 10 is securely fixed to the valve 20 via the first fixing portion 2. The connecting mechanism 10 is designed to be highly flexible, consisting of multiple detachable and rotatable connecting units 1. This allows the extension direction of the entire connecting mechanism 10 to be flexibly adjusted based on the specific space within which the valve 20 is located. This ensures that a suitable installation location for the sensor 30 can be found even in compact installation environments.

[0048] Next, we will combine Figures 2 to 7 The specific structure and function of the connecting mechanism 10 will be described.

[0049] Figure 2 yes Figure 1 Schematic diagram of the connecting mechanism 10, that is, Figure 2 A connecting mechanism 10 for a valve 20 according to an embodiment of the present application is shown.

[0050] Specifically, the connecting mechanism 10 includes: at least one connecting unit 1 connected in sequence, wherein each connecting unit 1 includes a first surface 11 and a second surface 12 having a non-zero angle, the first surface 11 of the previous connecting unit 1 is detachably connected to the second surface 12 of the next connecting unit 1, and the extension direction of the connecting mechanism 10 changes with the deflection angle of the first surface 11 of the previous connecting unit 1 relative to the second surface 12 of the next connecting unit 1; a first fixing portion 2, used to fix the first connecting unit 101 in at least one connecting unit 1 to the valve 20; a second fixing portion 3, connected to the last connecting unit 102 in at least one connecting unit 1, and the second fixing portion 3 is used to position a sensor 30.

[0051] More specifically, the connection mechanism 10 may be composed of one or more connection units 1. Furthermore, for each connection unit 1, a non-zero angle may be formed between the first surface 11 and the second surface 12. This angle allows adjacent connection units 1 to be connected or spliced together at a certain angle in space, thereby achieving a flexible layout of the connection mechanism 10 in three dimensions.

[0052] Furthermore, the first surface 11 of the preceding connection unit 1 is detachably connected to the second surface 12 of the succeeding connection unit 1. This facilitates the connection mechanism 10 to increase or decrease the number of connection units 1 as needed, thereby adjusting the overall length and shape of the connection mechanism 10.

[0053] Furthermore, based on the angle design and detachable connection design between adjacent connection units 1, the extension direction of the connection mechanism 10 can be changed as the deflection angle of the first surface 11 of the previous connection unit 1 relative to the second surface 12 of the next connection unit 1 changes. This flexibility enables the connection mechanism 10 to adapt to different installation environments and space constraints. For example, the first surface 11 of the previous connection unit 1 and the second surface 12 of the next connection unit 1 are adjacent and form an obtuse angle, the second surface 12 of the previous connection unit 1 and the first surface 11 of the next connection unit 1 are face to face, and the third surface 13 of the previous connection unit 1 and the third surface 13 of the next connection unit 1 are adjacent and form an acute angle. At this time, the extension direction of the connection mechanism 10 at these two connection units 1 turns (such as Figure 2 For example, refer to Figure 5 , the first surface 11 of the front connecting unit 1 is parallel to the second surface 12 of the rear connecting unit 1, the second surface 12 of the front connecting unit 1 is in contact with the first surface 11 of the rear connecting unit 1, and the third surface 13 of the front connecting unit 1 is parallel to the third surface 13 of the rear connecting unit 1. At this time, the extension direction of the connecting mechanism 10 at the two connecting units 1 remains unchanged (such as Figure 2 the section where the straight line extends from the middle).

[0054] Further, combined Figures 3 to 5 , the shape and size of the at least one connecting unit 1 are the same. In other words, all the connecting units 1 used in the connecting mechanism 10 have the same shape and size, that is, each connecting unit 1 can adopt a standardized design.

[0055] In some embodiments, since all connection units 1 have the same shape and size, they can be interchanged. Consequently, when assembling or repairing the connection mechanism 10, there is no need to distinguish between different connection units 1, thereby simplifying the installation and replacement process. Standardized connection units 1 allow the user to easily adjust the length and shape of the connection mechanism 10 as needed. Furthermore, by simply increasing or decreasing the number of connection units 1, the connection mechanism 10 can adapt to different installation environments and space constraints. Furthermore, standardized connection units 1 can effectively simplify the production process and reduce production costs.

[0056] Continue to refer Figure 3 In some embodiments, the connection unit 1 further includes: a third surface 13, which together with the first surface 11 and the second surface 12 forms a columnar structure, and the third surfaces 13 of adjacent connection units 1 are not coplanar.

[0057] Specifically, each connection unit 1 includes, in addition to the first surface 11 and the second surface 12, a third surface 13. The columnar structure formed by the first surface 11, the second surface 12, and the third surface 13 forms a three-dimensional structure of the connection unit 1 in space, thereby increasing the rigidity and stability of the connection unit 1 and providing it with better resistance to torsion and bending.

[0058] Furthermore, when multiple connection units 1 are connected sequentially, the third surfaces 13 of adjacent connection units 1 do not lie on the same plane. This allows the connection mechanism 10 to form more complex and diverse shapes in space. Because the third surfaces 13 are not coplanar, the connection mechanism 10 can achieve more flexible layout and rotation in three-dimensional space, adapting to different installation environments and space constraints.

[0059] In some embodiments, the shape of the connection unit 1 can be, for example, a triangular prism, and the first surface 11, the second surface 12, and the third surface 13 can be three side surfaces of the triangular prism, respectively. Thus, the overall structural strength and stability of the connection mechanism 10 composed of at least one connection unit 1 can be further improved.

[0060] In some embodiments, continue to refer to Figure 3 and Figure 5 The connecting unit 1 further includes: a coupling portion 14, arranged on the first surface 11; a mating portion 15, arranged on the second surface 12, and the mating portion 15 is used to cooperate with the coupling portion 14 of the adjacent connecting unit 1 to connect two adjacent connecting units 1.

[0061] Specifically, the coupling portion 14 is used to provide a connection point or interface to facilitate cooperation with the cooperation portion 15 on the second surface 12 of the adjacent connection unit 1 , thereby achieving the connection between the two connection units 1 .

[0062] Correspondingly, the matching portion corresponding to the coupling portion 14 is provided on the second surface 12 of the connection unit 1. The shape, size and position of the matching portion 15 are corresponding to and matched with the coupling portion 14. Thus, it is possible to ensure that the two connection units 1 can be accurately and firmly connected together.

[0063] Furthermore, through the cooperation between the coupling portion 14 and the mating portion 15, two adjacent connection units 1 can be securely connected together. This connection method is not only simple and reliable, but also easy to disassemble and replace. When the length or shape of the connection mechanism 10 needs to be adjusted, simply add or replace a new connection unit 1.

[0064] In some embodiments, the coupling portion 14 includes a protrusion 141, which protrudes outward from the first surface 11; the mating portion 15 includes a recessed portion 151, which is recessed inward from the second surface 12 of the connecting unit 1, and the protrusion 141 can be inserted into the recessed portion 151 of the adjacent connecting unit 1.

[0065] In some embodiments, the protrusion 141 may be a cylindrical, conical, spherical or other shaped structure to provide an insertable connection point for mating with the mating portion 15 of the adjacent connection unit 1 .

[0066] Correspondingly, the recessed portion 151 is recessed inward from the second surface 12 of the connecting unit 1, corresponding to the protruding portion 141. The shape, size and position of the recessed portion 151 match the protruding portion 141 to ensure that the two connecting units 1 can be accurately and firmly connected together.

[0067] In a typical application scenario, when two adjacent connection units 1 are connected, the protrusion 141 of a connection unit 1 can be inserted into the recess 151 of the adjacent connection unit 1. This plug-in connection method is not only simple and reliable, but also provides a certain degree of connection strength and stability. At the same time, because the design of the protrusion 141 and recess 151 is standardized, the connection method between all connection units 1 is the same, which further simplifies the assembly and maintenance process of the connection mechanism 10.

[0068] Furthermore, when the protrusion 141 is inserted into the recess 151 of the adjacent connection unit 1 , the outer peripheral surface of the protrusion 141 can be in close contact with the inner wall of the recess 141 to increase the tightness and firmness of the connection between the two adjacent connection units 1 .

[0069] Furthermore, the cross-sectional shape of the protrusion 141 includes at least one vertex angle, thereby helping to stabilize the deviation angle between two adjacent connection units 1 and preventing accidental rotation between one connection unit 1 and an adjacent connection unit 1 during use of the connection mechanism 10, which could cause the sensor 20 to fail or even be damaged by collision.

[0070] The cross-sectional shape refers to the shape of the protrusion 141 along a plane perpendicular to its protruding direction. Furthermore, the cross-sectional shape of the protrusion 141 includes at least one vertex angle. This vertex angle can be a sharp point in the cross-sectional shape of the protrusion 141, or it can be an angle formed by the intersection of two or more edges. The presence of the vertex angle allows the protrusion 141 to provide a better locking effect when inserted into the recess 151, thereby increasing the firmness and stability of the connection.

[0071] In a typical application scenario, when the top corner of the protrusion 141 is inserted into the recess 151, due to the sharpness of the top corner or the design of the included angle, a certain extrusion effect will be generated on the contact surface, thereby increasing the locking force between adjacent connection units 1.

[0072] In some embodiments, as Figure 3 and Figure 4 As shown, the cross section of the protrusion 141 can be, for example, square or rectangular. Square and rectangle are common geometric shapes, and the cross section of square or rectangular shapes can be easily manufactured by die stamping, cutting or injection molding, thereby reducing production costs.

[0073] In other embodiments, the cross-sectional shape of the protrusion 141 may also be a polygon, such as a regular pentagon or a regular hexagon. This allows for more combinations of rotation angles between two adjacent connection units 1. Taking the example of a protrusion 141 having a regular hexagonal cross-sectional shape, the deflection angles between two adjacent connection units 1 may be 60°, 120°, 180°, 240°, and 300°. This provides a wider range of options for the extension direction of the connection mechanism 10.

[0074] In some embodiments, the coupling portion 14 and the mating portion 15 may each comprise a magnetic connector, through which adjacent connection units 1 are magnetically connected. Thus, when two adjacent connection units 1 need to be connected, their respective coupling portions 14 and mating portions 15 approach and attract each other, thereby achieving a secure magnetic connection. This connection method is not only simple and easy to implement, but also provides a stable connection, ensuring the stability and reliability of the connection mechanism 10 within the overall structure.

[0075] In some embodiments, the connection mechanism 10 further includes a fixing member 4, which is used to connect at least two adjacent connection units 1. This can further increase the firmness of the connection between the two adjacent connection units 1.

[0076] In some embodiments, the fixing member 4 may be, for example, a screw or a bolt.

[0077] Continue to refer Figure 5 The connecting unit 1 further includes: a first assembly hole 111, which is opened on the first surface 11; a second assembly hole 121, which is opened on the second surface 12; the fixing member 4 passes through one of the first assembly hole 111 and the second assembly hole 121 and extends into the other of the first assembly hole 111 and the second assembly hole 121 of the adjacent connecting unit 1.

[0078] In a typical application scenario, when two adjacent connection units 1 need to be detachably connected together, the fixing member 4 can first be passed through the first assembly hole 111 (or second assembly hole 121) of one connection unit 1 and then extended into the second assembly hole 121 (or first assembly hole 111) of the adjacent connection unit 1. Furthermore, the fixing member 4 is installed in place by rotating or other means, thereby achieving a physical connection between the two connection units 1. Thus, the fixing member 4 can provide a more stable and secure connection between the two adjacent connection units 1.

[0079] Furthermore, at least one of the first assembly hole 111 and the second assembly hole 121 is a through-hole structure to facilitate the installation of the fixing member 4 .

[0080] like Figures 3 to 5 As shown, in some embodiments, the second assembly hole 121 is configured as a through-hole structure. When the second surface 12 of the preceding assembly unit 1 and the first surface 11 of the succeeding assembly unit 1 are aligned, the second assembly hole 121 and the first assembly hole 111 are connected and connected. Furthermore, the fixing member 4 can be inserted into the second assembly hole 121 from the opening on the side of the second assembly hole 121 away from the first assembly hole 111 and then continue into the first assembly hole 111. In this way, the two adjacent connection units 1 are firmly connected together.

[0081] Furthermore, the through hole structure includes a first hole segment 1211 and a second hole segment 1212 that are connected, wherein the first hole segment 1211 is closer to the first surface 11 or the second surface 12 than the second hole segment 1212, and the aperture of the second hole segment 1212 is larger than the aperture of the first hole segment 1211.

[0082] In a specific embodiment, the first hole section 1211 and the second hole section 1212 are connected on the same axis to form a complete through-hole structure for the fixing member 4 to be inserted.

[0083] In some embodiments, the second assembly hole 121 can be, for example, a through-hole structure, further comprising a first hole segment 1211 and a second hole segment 1212. The first hole segment 1211 is closer to the second surface 12 than the second hole segment 1212. The diameter of the second hole segment 1212 is larger than the diameter of the first hole segment 1211. Thus, the fixing member 4 can enter the second assembly hole 121 through the second hole segment 1212 and further pass through the first hole segment 1211, at least partially inserting into the first assembly hole 111. The larger diameter of the second hole segment 121 facilitates installation of the fixing member 4.

[0084] Continue to refer Figure 5 The fixing member 4 may include a stopper 41 and an extension portion 42. When the fixing member 4 is installed, a portion of the extension portion 42 extends into the first assembly hole 111, while the other portion remains in the first hole section 1211 of the second assembly hole 121 of the adjacent connecting unit 1. The stopper 41 is located in the second hole section 1212 and abuts against the step structure formed between the second hole section 1212 and the first hole section 1211. This increases the tightness of the connection between the fixing member 4 and the two adjacent connecting units 1.

[0085] Furthermore, a threaded structure may be provided on the outer peripheral surface of the extending portion 42 and the inner walls of the first hole section 1211 and the second hole section 1212 , and the fixing member 4 is detachably connected to two adjacent connecting units 1 at the same time by threaded engagement.

[0086] In some embodiments, the included angle between the first surface 11 and the second surface 12 may be an obtuse angle, thereby avoiding mutual interference between the first assembly hole 111 and the second assembly hole 121 .

[0087] In some embodiments, combined Figure 1 、 Figure 2 and Figure 6 The first fixing portion 2 is connected to the second surface 12 of the first connecting unit 101 . The first fixing portion 2 is provided with a first adapting portion 201 . The first adapting portion 201 is used to adapt to the matching portion 15 .

[0088] Specifically, the first fixing portion 2 may include a first clamping plate 21 connected to the first connecting unit 101, with the first adapting portion 201 disposed on the first clamping plate 21; and a second clamping plate 22 disposed opposite the first clamping plate 21. The first clamping plate 21 and the second clamping plate 22 clamp at least a portion of the valve 20. Thus, the first clamping plate 21 and the second clamping plate 22 can stably clamp at least a portion of the valve 20, ensuring that the connecting mechanism 10 and the sensor 30 can stably and synchronously move with the valve 20.

[0089] In some embodiments, the first clamping plate 21 and the second clamping plate 22 may be connected by connecting members such as screws.

[0090] In some embodiments, the shape of at least one of the first clamping plate 21 and the second clamping plate 22 can be adapted to the portion of the valve 20 being clamped. For example, the first clamping plate 21 or the second clamping plate 22 can be bent to form a groove to accommodate the clamped portion of the valve 20. This can further enhance the stability of the connection between the first fixing portion 2 and the valve 20.

[0091] Furthermore, the first adapter portion 201 is provided on the surface of the first clamping plate 21 facing the first connecting unit 101 and is used to cooperate with the matching portion 15 of the first connecting unit 101. The structure and function of the first adapter portion 201 can refer to the above description of the coupling portion 14.

[0092] In some embodiments, combined Figure 1 、 Figure 2 and Figure 7 The second fixing portion 3 is connected to the first surface 11 of the last connecting unit 102. The second fixing portion 3 is provided with a second adapting portion 301, which is used to adapt to the coupling portion 14. The structure and function of the second adapting portion 301 can be referred to the above description of the matching portion 15.

[0093] In some embodiments, the fixing member 4 may be used to connect the first connecting unit 101 and the first fixing portion 2. Thus, the connection between the first connecting unit 101 and the first fixing portion 2 may be more stable.

[0094] In some embodiments, the fixing member 4 may be used to connect the last connecting unit 102 and the second fixing portion 3. Thus, the connection between the last connecting unit 102 and the second fixing portion 3 may be more stable.

[0095] As described above, using the technical solution of the present application, the connecting mechanism 10 is composed of a plurality of detachable and deflectable connecting units 1, so that the extension direction of the connecting mechanism 10 can be flexibly adjusted according to the specific space where the valve 20 is located. This design greatly improves the flexibility and adaptability during installation, allowing the sensor 30 to find a suitable installation position even in a compact space. Due to the deflection connection between the connecting units 1, the sensor 30 can move away from potential collision points through a tortuous path, thereby avoiding direct contact with surrounding components. This not only protects the sensor 30 from damage, but also reduces the risk of performance degradation or failure due to collision.

[0096] Furthermore, the detachable connection design between the connecting units 1 makes the installation process easier. At the same time, when the sensor 30 needs to be maintained or replaced, the connecting mechanism 10 can be easily disassembled, reducing the maintenance difficulty and cost.

[0097] Furthermore, at least one connection unit 1 has the same shape and size, which helps to achieve standardized production and reduce costs. In addition, the modular design allows the number of connection units 1 to be increased or decreased according to actual needs to meet the needs of valves 20 of different sizes and shapes.

[0098] Furthermore, the coordination of the protrusion 141 and the recess 151, the use of the magnetic connector, and the support of the fixing member 4 can enhance the stability and reliability of the connection mechanism 10, ensuring a secure connection between the sensor 30 and the valve 20 even in harsh working environments.
