[0001] The utility model relates to the technical field of instrumentation, in particular to a shell device for a pipe fitting with a valve and an intelligent control assembly thereof. Background Art

[0002] Smart instruments combine actuators with traditional valves to achieve the valve opening and closing functions of intelligent control instruments. An actuator is a combination of an actuator and a control valve in an automatic control system. Its role in an automatic control system is to receive signals from a regulator and, based on its position and characteristics in the process pipeline, adjust the flow of the process medium, thereby keeping the controlled quantity within the range required by the production process.

[0003] Prior art example 1, referring to patent document CN218121065U, discloses a smart water meter housing protective structure, relating to the field of smart water meter technology, comprising a central control housing, antifreeze glass, an adapter, and symmetrical front fixing holes. A battery compartment is mounted on the top of the central control housing, an actuator chamber is disposed on the inner side of the central control housing, a communication compartment is disposed on the top of the central control housing, a mainboard compartment is mounted on the inner side of the central control housing, a battery cover is mounted on the inner side of the central control housing, a rubber ring is disposed on the bottom of the battery cover, a double rubber ring is disposed on the bottom of the rubber ring, and the double rubber ring is connected to the bottom of the battery cover. An actuator positioning fixing hole is disposed within the actuator chamber. This utility model achieves an improved overall sealing effect for the smart water meter housing by isolating each chamber to achieve independent sealing of each unit. The circuit board is simultaneously encapsulated with immersion-type transparent silicone gel. An adapter is added between the actuator and the base meter valve stem, and multiple rubber ring seals are added to the rotating contact area. However, the defect of Example 1 is that it maintains stability by tightly fitting with the outer wall of the smart water meter, but can only be installed on smart water meters of a single size and model, and cannot protect most smart meters (water meters, pipe valve meters, etc.), and the installation is relatively loose and the stability is poor.

[0004] Prior art example 2, referring to patent document CN213368336U, discloses a waterproof smart meter housing and a smart meter, comprising the above-mentioned waterproof smart meter housing, and a circuit communication component, a battery component and an actuator component arranged in the second accommodating cavity of the waterproof smart meter housing; wherein the waterproof smart meter housing comprises a cover body, a main housing and a bottom housing arranged in sequence from top to bottom, a first accommodating cavity for accommodating external accessories is formed between the main housing and the bottom housing, and a first opening and a second opening communicating with the first accommodating cavity are provided on the bottom housing; the cover body is provided on the main housing and forms a second accommodating cavity, wherein the main housing also provides an output through hole communicating with the first accommodating cavity and the second accommodating cavity. Example 2 is an earlier research and development result of the applicant in this case. After a period of market testing, some minor problems were exposed, such as: 1. The power supply is entirely inside the box, and a better power supply requires the entire box to be opened, so the operation is more cumbersome; 2. The space between the bottom shell and the main shell is used to accommodate external accessories, but the shape and size of the bottom shell and the main shell are fixed, so the size of the external accessories will be greatly limited, and it cannot meet the needs of multi-shaped and large-sized accessories to be connected therein.

[0045] Example 1

[0046] Reference Figures 1 to 12 A housing device for a valved pipe fitting comprises: a main box body 1, which is composed of a bottom box 11, a top cover 12 and a side cover 13; the top cover 12 is detachably assembled to the upper end of the bottom box 11, so that a receiving cavity 14 is formed between the top cover 12 and the bottom box 11; the side of the bottom box 11 has a side opening 111, and the side cover 13 is detachably assembled to the side opening 111. During use, if it is necessary to remove or install a battery, it is only necessary to open the side cover 13 relative to the bottom box 11 separately to expose the side opening 111, and then the battery can be placed into or removed from the receiving cavity 14 through the side opening 111. After the battery is replaced, the side cover 13 is reassembled to the bottom box 11 to cover the side opening 111 and provide effective physical protection for the battery in the receiving cavity 14. The first adapter seat 2 has its upper end assembled to the lower end of the base box 11, and its lower end assembled to the upper end of the pipe fitting 4, and a through-type transmission through hole 21 is provided on the first adapter seat 2, and an output hole 112 is provided at the lower end of the base box 11. The output hole 112 and the transmission through hole 21 are aligned with each other and connected to provide a transmission space to realize the transmission cooperation between the actuator 6 and the valve stem 43 on the pipe fitting 4; the second adapter seat 3 has a buffer 321 at its upper end, and the buffer 321 abuts against the lower end of the base box 11, which can better fit the base box 11, eliminate the gap between the two, and adaptively form a tight fit, thereby reducing / eliminating the shaking caused by the fitting gap, making the overall structure more stable and reliable; the second adapter seat 3 has a plurality of support sections 311 at the lower end, and the support sections 311 are fixedly connected to the pipe fitting 4. In this embodiment, the first adapter 2 and the second adapter 3 can respectively form multi-point connection fixation with the pipe 4 and the bottom box 11, so that the shell device can form a stronger connection effect with the pipe 4 to ensure that there will be no loosening and other problems between the components during use, ensuring long-term and reliable use.

[0047] In some preferred embodiments of the present invention, Figure 3 The accommodating cavity 14 includes an independent battery chamber 141 and an actuator 6 chamber 142, and the lateral opening 111 is provided at the side end of the battery chamber 141; Figure 6The battery chamber 141 has a cable opening 143 formed in its wall. The battery chamber 141 is partially connected to the battery chamber 141 through the cable opening 143, facilitating cable routing. The use of an independent battery chamber 141 separates the battery chamber 141 from the actuator chamber 142. This provides better protection for the batteries installed within and prevents battery fluid from entering the actuator chamber 142 should a battery leak occur, thereby providing excellent protection for the components within the actuator chamber 142.

[0048] Optionally, a mounting bracket 144 is further provided at the upper end of the battery chamber 141 to provide support and mounting points to facilitate installation and use of the sampling circuit board 5 .

[0049] Example 2

[0050] Since the side cover 13 is installed laterally on the bottom box 11, it is impossible to completely avoid the external force during use, and the side cover 13 is at risk of loosening or falling off, causing water, dust and other impurities to enter the accommodating cavity 14, thereby affecting normal use.

[0051] In order to eliminate the above hidden dangers, based on the structure of the first embodiment, this embodiment also adds an optimized structural solution, specifically: Figure 1 、 Figure 6 The side wall of the top cover 12 is provided with a first lug 121, and the side cover 13 is provided with a second lug 131. The first lug 121 and the second lug 131 are provided with matching lug connecting holes 122; after the top cover 12 and the side cover 13 are respectively assembled to the bottom box 11, the first fasteners (such as screws, etc., not shown in the drawings) are inserted into the lug connecting holes 122 to connect the bottom box 11, the top cover 12 and the side cover 13 to each other.

[0052] By setting the first lug 121 and the second lug 131, a connection structure is provided, and then the first fastener is connected to each lug connection hole 122 to connect the bottom box 11, the top cover 12 and the side cover 13 to each other. The defect of the side cover 13 falling off or losing is completely eliminated to provide a stable and reliable accommodating chamber.

[0053] Preferably, refer to Figure 8The bottom box 11 has two lateral openings 111 distributed on both sides of the bottom box 11, and the side covers 13 have two corresponding to the lateral openings 111. The structure of double lateral openings 111 is applicable to more installation scenarios. Specifically, the environment of the installation location is not uniform. For example, there may be a wall 7 outside, and the wall 7 may be located on the left or right side. If a single lateral opening 111 structure is used, the lateral opening 111 will be blocked by the wall 7 in some scenarios and cannot be used normally, requiring other methods to replace the battery. Therefore, the double lateral openings 111 solve the above problem, making it more convenient and quick to use.

[0054] Example 3

[0055] In this embodiment, a preferred structural solution for the first adapter 2 and the second adapter 3 is provided, as follows:

[0056] First adapter 2: reference Figures 9 and 10 , including a cylindrical main body 22 and an extension portion 23 protruding on both sides of the cylindrical main body 22, wherein the transmission through hole 21 is arranged on the cylindrical main body 22; wherein the extension portion 23 is provided with an upper connecting hole 231 for cooperating with the bottom box 11, and the cylindrical main body 22 is provided with a lower connecting hole 221 for cooperating with the pipe 4.

[0057] Second adapter 3: refer to Figures 11 and 12 , including a rectangular frame 31 with an opening at the lower end, a raised portion 32 arranged at the upper end of the rectangular frame 31, the buffer 321 arranged at the upper end of the raised portion 32, the support section 311 arranged in the rectangular frame 31, and the support section 311 is provided with a number of support holes for matching the pipe 4. Among them, the rectangular frame 31 can provide a certain shielding and protection for the pipe 4. Optionally, the buffer 321 is a soft rubber pad or sponge, etc. During the assembly process, the buffer 321 at the upper end of the raised portion 32 contacts the bottom box 11, and the buffer 321 adaptively deforms after being subjected to force to fill the gap. During use, when the bottom box 11 or the pipe 4 is impacted, the impact force can be partially or completely offset (absorbed) when transmitted to the buffer 321, thereby eliminating the occurrence of shaking and structural instability, ensuring the continuous and stable use of the entire machine.

[0058] Example 4

[0059] Reference Figures 1 to 3The present invention also provides an intelligent control assembly, comprising the aforementioned housing device for the valved pipe fitting, an actuator 6, a battery (consistent with the prior art and not shown in the figures), a sampling circuit board 5, and a pipe fitting 4. The actuator 6, battery, and sampling circuit board 5 are all mounted in a housing 14, with the end of the battery facing the lateral opening 111. The output end 61 of the actuator 6 extends downward through the output hole 112 and into the transmission through hole 21. The pipe fitting 4 is connected to the first adapter 2 and the second adapter 3, respectively. The valve stem 43 of the pipe fitting 4 extends upward into the transmission through hole 21 and forms a transmission connection with the output end 61 of the actuator 6. More specifically, the pipe fitting 4 has a first positioning end 41 and a plurality of second positioning ends 42. The first positioning end 41 is connected to the first adapter 2, and the second positioning end 42 is connected to the support section 311 of the second adapter 3.

[0060] During assembly, the actuator 6, battery, and sampling circuit board 5 are sequentially assembled into the housing assembly. The pipe 4 is then connected and secured to the first adapter 2 and second adapter 3, respectively. Finally, the entire pipe 4 (including the pipe 4, first adapter 2, and second adapter 3) is assembled with the base box 11 (housing assembly). In this final step, only the first adapter 2 and base box 11 need to be connected using a second fastener (such as a screw), and the second adapter 3 is abutted against the base box 11 (no screw connection is required). This simplifies the overall assembly process, increases efficiency, and provides a stable and reliable assembly result.

[0061] When in use, the battery provides power, and the actuator 6 is started after receiving a signal, so that the output end 61 of the actuator 6 drives the valve stem 43 of the pipe fitting 4 to achieve the opening and closing of the pipe fitting 4 and the regulation and control of the flow rate.

[0062] It is worth noting that other technical solutions of the present invention belong to the existing technology and are therefore not described in detail.

[0063] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the concept of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
