Description

Technical Field

[0001] This utility model belongs to the field of valve-controlled water meter technology, and in particular relates to a sealing structure of a valve-controlled water meter intelligent module actuator. Background Technology

[0002] Valve-controlled water meters, as key devices for water metering and control, are widely used in residential and industrial water use scenarios. With the development of intelligent technology, valve-controlled water meters are gradually integrating intelligent modules, using actuators to achieve automatic on / off control of valves, thereby enabling functions such as remote meter reading and valve shut-off for overdue payments.

[0003] The core components of the intelligent module include the main control board and the actuator: the main control board is responsible for receiving instructions, processing data, and sending control signals to the actuator; the actuator then drives the water meter valve to operate according to the control signals. Since the water meter operates in a humid environment (such as basements, wells, etc.) for a long time and may come into contact with water, dust, and other impurities, the sealing performance of the main control board and the actuator directly affects the reliability and service life of the valve-controlled water meter.

[0004] The sealing structure of existing valve-controlled water meter smart module actuators has the following defects: 1. Limited Sealing Methods: Many systems rely on a single sealing ring or potting compound, making them ill-suited for complex, humid environments. For example, when relying solely on a sealing ring, the ring ages over time, allowing moisture to seep in; when relying solely on potting compound, air bubbles or gaps can easily appear if the potting area is poorly designed, resulting in ineffective sealing.

[0005] 2. Poor component assembly stability: The connection between the main control board and the actuator, and between the module box and the base lacks a reliable positioning and fastening structure. Misalignment is prone to occur during assembly, which not only affects the sealing performance but may also lead to poor electrical connection.

[0006] 3. Insufficient sealing of the transmission part between the actuator and the water meter valve stem: This part is a high-risk area for water vapor intrusion. Traditional structures often only have a single seal, which is difficult to effectively prevent water vapor from entering the actuator.

[0007] Therefore, there is an urgent need for a sealing structure for the actuator of the valve-controlled water meter intelligent module that has excellent sealing performance, stable assembly, and adaptability to complex environments, in order to solve the problems existing in the current technology.

[0013] As a preferred embodiment of this utility model, two third grooves are formed on the water meter valve stem, and a first sealing ring is assembled in the third groove.

[0014] In a preferred embodiment of this utility model, the inner wall of the connecting part is fitted to the outer wall of the base.

[0015] As a preferred embodiment of this utility model, a second groove is formed between the connecting part and the mounting part, the end of the base is built into the second groove, and a sealing gasket is fitted into the second groove.

[0016] As a preferred embodiment of this utility model, a plurality of guide blocks are formed on the outer side wall of the base, and correspondingly, a plurality of locking holes adapted to the guide blocks are formed on the connecting part. When the base is assembled with the module box, the guide blocks are built into the locking holes to fasten the base and the module box.

[0017] As a preferred embodiment of the present invention, a guide inclined surface is formed on the inner circumferential side of the bottom of the connecting part, and the distance between the guide inclined surfaces gradually decreases along the insertion direction.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0026] Example

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 7 and Figure 8 As shown, the present invention discloses a sealing structure for a valve-controlled water meter intelligent module actuator, including a base 4 and a module box 7 mounted on the base 4; the module box 7 includes a mounting part 70 and a connecting part 71 that are connected to each other; a mounting groove 72 is formed in the mounting part 70, and the main control board 8 is placed in the mounting groove 72; the connecting part 71 is sealed to the base 4; for fixing and sealing the module box 7 and the base 4.

[0028] The base 4 has a cavity 40, and the actuator 5 is assembled in the cavity 40. The actuator 5 is correspondingly arranged and connected to the main control board 8. The electrical connection is achieved through wires or connectors to ensure that the main control board can stably transmit control signals to the actuator. In this embodiment, the actuator 5 and the main control board 8 are connected by welding.

[0029] To achieve multiple seals, potting areas are formed between the mounting groove 72 and the main control board 8, between the accommodating cavity 40 and the actuator 5, and between the main control board 8 and the actuator 5. These potting areas are used to fill with sealant. The sealant can be epoxy resin sealant. After curing, the sealant can fill the gaps between the components, forming a continuous sealing barrier that effectively prevents moisture, dust, and other impurities from intruding.

[0030] This invention features multiple sealing methods and high reliability. It combines sealing with adhesive filling, sealing rings, and sealing gaskets to form a comprehensive sealing barrier: the sealant filling the injection area fills the gaps between components, achieving overall sealing; the first and second sealing rings enhance the seal between the water meter valve stem and the through hole, and between the actuator and the base, respectively; the sealing gasket strengthens the connection seal between the module box and the base. This synergistic effect of multiple seals effectively prevents moisture and dust intrusion, significantly improving sealing reliability.

[0031] like Figure 4 As shown, the bottom of the base 4 is provided with a through hole 41, and the bottom of the actuator 5 is provided with a control rod 50. The control rod 50 is located at the position opposite to the through hole 41 and extends into the through hole 41. The control rod 50 extends to the outside of the base 4 through the through hole 41 and is used to cooperate with the valve transmission structure of the water meter.

[0032] like Figure 2 , Figure 3 and Figure 5 As shown, the bottom of the actuator 5 is provided with a first groove 51, which is arranged circumferentially along the control rod 50. Correspondingly, the bottom of the base 4 is provided with a limiting sleeve 42 that is adapted to the first groove 51. The limiting sleeve 42 is arranged opposite to the through hole 41. A second sealing ring 3 is assembled in the first groove 51. The second sealing ring 3 can be selected such as a nitrile rubber sealing ring.

[0033] Specifically, the engagement of the limiting sleeve 42 with the first groove 51 can radially position the actuator 5, preventing the actuator 5 from shaking within the accommodating cavity 40; the second sealing ring 3 can enhance the sealing performance between the actuator 5 and the bottom of the base 4, preventing moisture from entering the accommodating cavity 40 through the gap between them.

[0034] like Figure 4 and Figure 6As shown, a water meter valve stem 2 adapted to the control rod 50 is installed in the through hole 41. The water meter valve stem 2 is used to drive the control rod 50. The cooperation between the control rod 50 and the water meter valve stem 2 is used for the valve transmission of the water meter, thereby realizing the on-off control of the valve.

[0035] Specifically, the water meter valve stem 2 can be connected to the control rod 50 by means of snap-fit, threaded connection or pin connection. When the actuator 5 drives the control rod 50 to rotate or move axially, the control rod 50 drives the water meter valve stem 2 to move synchronously, thereby controlling the opening or closing of the water meter valve.

[0036] like Figure 2 As shown, two third grooves 20 are formed on the water meter valve stem 2, and a first sealing ring 1 is installed in the third groove 20. The first sealing ring 1 can be a fluororubber sealing ring. The two first sealing rings 1 are spaced apart along the axial direction of the water meter valve stem 2, which can form a double seal between the through hole and the water meter valve stem, effectively preventing water or water vapor inside the water meter from entering the receiving cavity upward through the gap between the through hole and the water meter valve stem.

[0037] The inner wall of the connecting part 71 fits against the outer wall of the base 4; this structural design can increase the contact area between the connecting part 71 and the base 4, improve the stability of the connection between the two, and provide a reliable installation base for subsequent sealing structures (such as sealing gasket 6).

[0038] like Figure 7 and Figure 8 As shown, a second groove 74 is formed between the connecting part 71 and the mounting part 70. The end of the base 4 is built into the second groove 74, and a sealing gasket 6 is installed in the second groove 74. The sealing gasket 6 can be a silicone sealing gasket. The sealing gasket 6 is pressed between the second groove 71 and the end of the base 4, which can effectively prevent external moisture from entering from the connection gap between the module box 7 and the base 4. It works synergistically with the potting sealant to further improve the overall sealing performance.

[0039] like Figure 4 and Figure 8 As shown, multiple guide blocks 43 are formed on the outer side wall of the base 4. Correspondingly, multiple locking holes 75 that are adapted to the guide blocks 43 are formed on the connecting part 71. When the base 4 is assembled with the module box 7, the guide blocks 43 are built into the locking holes 75 to fasten the base 4 and the module box 7. The cooperation between the guide blocks 43 and the locking holes 75 can realize the quick positioning and reliable connection of the base 4 and the module box 7, avoid relative displacement between the two during use, and ensure the stability of the sealing structure.

[0040] like Figure 8As shown, a guide inclined surface 73 is formed on the inner circumferential side of the bottom of the connecting part 71. The distance between the guide inclined surfaces 73 gradually decreases along the insertion direction. The guide inclined surface 73 plays a guiding role when the module box 7 and the base 4 are assembled, which facilitates the guide block 43 to smoothly enter the locking hole 75, reduces the assembly difficulty, and improves the assembly efficiency.

[0041] This utility model features a stable structure and convenient assembly. The base and module box are fastened together by the guide block and locking hole. The fit design of the inner wall of the connecting part and the outer wall of the base ensures a stable connection between the two. The actuator achieves radial positioning through the cooperation of the limiting sleeve and the first groove. The main control board is fixed by the support component and the limiting component, ensuring accurate positioning of each component and preventing shaking or displacement. At the same time, the setting of the guide inclined surface reduces the assembly difficulty and improves the assembly efficiency.

[0042] like Figure 3 and Figure 7 As shown, the mounting groove 72 is provided with a support component 9 and a limiting component 10; the main control board 8 is detachably mounted on the support component 9 and the limiting component 10, and is locked by the locking component 11. The locking component 11 is a locking bolt, which is used to fasten the main control board 8.

[0043] The support component 9 is used to support the main control board 8, ensuring that there is a uniform glue gap between the main control board 8 and the mounting groove 72; wherein, the limiting component 10 includes a limiting block 12 and a limiting guide 13 with an L-shaped structure; the limiting block 12 and the limiting guide 13 are used to limit the displacement of the main control board 8 and prevent it from shaking during assembly or use; the detachable connection method facilitates the installation, maintenance and replacement of the main control board.

[0044] The assembly process in this embodiment is as follows: 1. Place the actuator 5 into the receiving cavity 40 of the base 4, so that the control rod 50 extends into the through hole 41, the limiting sleeve 42 is inserted into the first groove 51, and the second sealing ring 3 is pressed.

[0045] 2. Insert the water meter valve stem 2 into the lower end of the through hole 41, so that its upper end is connected to the control rod 50 through a spline, and the first sealing ring 1 is in contact with the inner wall of the through hole 41.

[0046] 3. The two first sealing rings 1 are fitted into the third groove 20 of the water meter valve stem 2 to form a double seal between the through hole and the water meter valve stem.

[0047] 4. Fix the main control board 8 to the support column of the mounting part 70 with screws, and then connect the main control board 8 to the actuator 5.

[0048] 5. Align the connecting part 71 of the module box 7 with the base 4 and insert it along the guide inclined surface 73 so that the guide block 43 enters the locking hole 75. The upper end surface of the base 4 presses the sealing gasket 6 to complete the assembly.

[0049] 6. Inject sealant into the three potting areas through the top of module box 7, and seal the actuator with the sealant.

[0050] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention; therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.

[0051] Although this document frequently uses reference numerals from the accompanying drawings, such as: first sealing ring 1, water meter valve stem 2, second sealing ring 3, base 4, actuator 5, sealing gasket 6, module box 7, main control board 8, support component 9, limiting component 10, locking component 11, limiting block 12, limiting guide 13, third groove 20, accommodating cavity 40, through hole 41, limiting sleeve 42, guide block 43, control rod 50, first groove 51, mounting part 70, connecting part 71, mounting groove 72, guide inclined surface 73, second groove 74, and locking hole 75, the possibility of using other terms is not excluded.
