Specific embodiments

[0048] To make the technical problems solved by the present utility model, the technical solutions adopted and the achieved technical effects clearer, the technical solutions of the embodiments of the present utility model will be further described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present utility model.

[0049] In the description of the present utility model, unless otherwise clearly defined and limited, the terms "connected", "connected", "fixed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection, an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the internal communication of two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0050] In the present utility model, unless otherwise clearly specified and defined, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features therebetween. Moreover, the first feature being "above", "over" and "on the top of" the second feature includes that the first feature is directly above and obliquely above the second feature, or merely indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature being "under", "beneath" and "underneath" the second feature includes that the first feature is directly below and obliquely below the second feature, or merely indicates that the horizontal height of the first feature is lower than that of the second feature.

[0051] An electric valve is an automated device that uses an electric device to control the opening and closing of the valve and regulate the flow rate and pressure of the valve. It drives the valve core (valve flap) of the valve through an actuator (also known as an electric device) to achieve the opening, closing, regulation and control of the valve.

[0052] In the prior art, a pressure sensor for monitoring the internal water pressure is generally provided on the water delivery pipe of the valve. The monitoring of the water pressure can intuitively reflect whether there are leakage problems in the valve and the pipeline system. While improving the reliability and stability of the system, it can also evaluate the opening and closing state and the opening degree of the valve according to the water pressure situation, so that the state of the valve can meet the usage requirements of the pipeline system.

[0053] As mentioned in the background art, in the related technology of valves, the pressure sensor is connected to the joint on the water delivery pipeline through a pressure conduit. As a device for connecting the water delivery pipe of the valve and the pressure conduit, the joint must be able to withstand the pressure and temperature of the fluid in the pipeline, maintain good sealing performance, and in order to adapt to more usage scenarios, the joint also needs to have a certain corrosion resistance. However, since the joint generally adopts a combination of multiple split structures to assemble in order to have good physical and chemical properties, it also leads to the situation of high production cost, large assembly difficulty and complex overall assembly structure of the joint, which is not conducive to the large-scale application of the pipeline system.

[0054] In view of this, the present embodiment provides a pipeline joint for a valve. It can be understood in combination with the above content that this pipeline joint can be applied to the valve in combination with a hydraulic detection device to transfer the pressure in the water delivery pipeline of the valve to the hydraulic detection device in the above usage scenario of the valve. This pipeline joint adopts an integrated design method to solve the problem of its redundant structure, and further opens a material-reducing groove on the basis of ensuring the structural strength of the pipeline joint, so as to achieve related purposes such as reducing the production cost and disassembly and assembly difficulty of the product.

[0055] For details, please refer to the attached drawings of the specification Figure 1 、 Figure 4The pipe joint includes a first connecting portion 10 and a mounting portion 20.

[0056] Among them, the first connection part 10 in this embodiment is used as one end of the pressure sensor, and is configured to be connected to the pressure sensor through the pressure conduit mentioned above. In some embodiments, the first connection part 10 and the pressure conduit can be assembled in a detachable connection to facilitate maintenance and replacement, and the assembly relationship between the first connection part 10 and the pressure conduit can be adaptively designed according to the specific use scenario of the valve, the design requirements of the pressure conduit, etc. The first connection part 10 and the pressure conduit can be connected by, but not limited to, threaded connection, flange connection, ferrule connection, plug-in connection and other connection methods, and accordingly, the structure of the first connection part 10 should also be adaptively adjusted according to the above connection methods.

[0057] Of course, the connection between the first connection portion 10 and the pressure conduit of this embodiment is not limited to the above-mentioned connection method. In other embodiments, the first connection portion 10 and the pressure conduit may also be connected in a non-detachable manner, such as welding, bonding, etc. This embodiment does not impose strict limitations and requirements on this.

[0058] Continuing with the above embodiment, the mounting portion 20 in this embodiment serves as a portion connected to the valve water supply pipeline of the above volume, and is used to provide a corresponding operating position for the disassembly and assembly tools or the hands of the operator during the disassembly and assembly of the pipe joint, so that the mounting portion 20 can control the pipe joint and allow it to be smoothly installed on the water supply pipeline. Therefore, the specific structure of the mounting portion 20 can be adaptively designed according to the disassembly and assembly method and connection structure between the pipe joint and the water supply pipeline, and this embodiment does not make corresponding limitations and requirements for the time being.

[0059] For example, in order to provide a corresponding operating position for disassembly and assembly tools, etc., the mounting portion 20 may be provided with, but not limited to, structures such as a wrench flat surface, a groove, and an anti-slip surface.

[0060] It can be understood from the above content that when a detachable connection is adopted between the pipe joint and the water supply pipeline, a second connection part 70 is further provided at the end of the mounting part 20 away from the first connection part 10. The second connection part 70 in this embodiment is used to cooperate with the mounting structure on the water supply pipeline, so that it can be matched with or detached from the water supply pipeline under the drive of the mounting part 20, and the second connection part 70, the mounting part 20 and the first connection part 10 are formed with sequentially connected delivery holes, and the first connection part 10 and the second connection part 70 are both provided with orifices connected to the delivery channel to ensure that the pressure in the delivery pipeline can be transmitted to the pressure sensor connected thereto through the delivery hole formed in the pipe joint.

[0061] According to the structural form provided above, in this embodiment, the installation part 20 and the first connection part 10 are set as an integral part, and the two can be specifically manufactured by an integral molding process. Moreover, the integral molding process can be selected according to the materials used for this pipeline joint, and is not limited to process methods such as injection molding, casting molding, 3D printing, etc. This embodiment does not make any restrictions on this.

[0062] The first connection part 10 and the installation part 20 are set as an integral part, so that no additional connectors or fasteners are required for secondary assembly during either the early production and manufacturing process or the later connection process with the water delivery pipeline or pressure conduit. This design method effectively reduces the number of component materials of the pipeline joint, thereby simplifying the production steps and assembly steps, and also making the overall structure of the pipeline joint simpler and more compact. The structural strength between the two depends on the material strength and the process method, without considering the assembly method, improving the overall strength and stability of the structure.

[0063] Moreover, due to the fact that the first connection part 10 and the installation part 20 are an integral part, the overall structure of the pipeline joint is also more compact, occupying less space and improving the applicability of the product to scenarios.

[0064] In addition, since this pipeline joint is mainly applied to valve products for transporting fluids and has high requirements for fluid tightness, therefore, due to the absence of assembly gaps between the integrally molded first connection part 10 and the installation part 20 (including the second connection part 70), the overall tightness of the pipeline joint is higher compared to joints using a modular design, thus avoiding the situation of fluid leakage due to the failure of the sealing structure after long-term use, and also reducing a series of risks caused by connection loosening or breakage.

[0065] Please continue to refer to the appendix Figure 1 On the basis of the integrally molded pipeline joint, a plurality of spaced-apart material reduction grooves 30 are formed in the installation part 20 in the direction of surrounding the first connection part 10. As the name implies, the material reduction grooves 30 are mainly used to reduce the weight of the installation part 20 and even the entire pipeline joint and reduce the materials consumed in production. In addition to being a groove structure formed in the installation part 20, it can also be a hole structure provided in the installation part 20. This embodiment does not make strict restrictions on this for the time being.

[0066] It can be understood that in this embodiment, the material reduction groove 30 is provided on the mounting portion 20. The main reason is to avoid the influence of the structure of the material reduction groove 30 on the structural strength of the first connecting portion 10 (and the second connecting portion 70), and to prevent the pressure conduit (or water pipeline) from interfering with the first connecting portion 10 (or the second connecting portion 70) when connecting to it. And, from the above content, since the mounting portion 20 is used to provide a corresponding operation position for disassembly and assembly tools and the like, the size of the mounting portion 20 is larger than that of the first connecting portion 10 (and the second connecting portion 70). Therefore, by opening the material reduction groove 30 on the mounting portion 20, the influence on the overall structural strength of the pipeline joint is relatively small, and its structural design is more reasonable.

[0067] It should be understood that while reducing the weight and cost of the mounting portion 20 through the material reduction groove 30, it is also necessary to ensure that the structural strength of the pipeline joint can meet its application requirements in the hydraulic detection device and even the valve. By arranging the material reduction grooves 30 at intervals along the direction around the first connecting portion 10, and in some embodiments, setting any two adjacent material reduction grooves 30 to have equal intervals and the same size, to avoid the situation that a certain area of the mounting portion 20 has a large groove or hole structure, the stress distribution on the pipeline joint can be optimized, so that the stress is more evenly distributed throughout the mounting portion 20, avoiding the problem of stress concentration, which helps to reduce material fatigue failure or crack propagation caused by stress concentration, and improve the durability and reliability of the pipeline joint.

[0068] It should be noted that the position of the material reduction groove 30 on the mounting portion 20 in this embodiment is not strictly limited. On the basis of not affecting the first connecting portion 10 and the second connecting portion 70, the material reduction groove 30 can be provided at various places on the mounting portion 20, as long as it satisfies the layout method that each material reduction groove 30 is arranged along the direction around the first connecting portion 10 and is spaced apart from each other.

[0069] Please refer to the appendix Figure 1, in this embodiment, the material-reducing groove 30 can refer to the first groove portion 31 in the drawing. The material-reducing groove 30 (the first groove portion 31) can be arranged close to the outer peripheral surface 22 of the mounting portion 20, and at least part of the notch of the material-reducing groove 30 is opened on the outer peripheral surface 22 of the mounting portion 20, so that the material-reducing groove 30 is located as far as possible from the first connecting portion 10. While ensuring that the connection strength between the mounting portion 20 and the first connecting portion 10 (and the second connecting portion 70) is not affected by the existence of the material-reducing groove 30, when the notch deforms due to the stress on the mounting portion 20, the deformation of the notch will not change the state of the first connecting portion 10 (and the second connecting portion 70), ensuring that the connection strength between the first connecting portion 10 and the pressure conduit and the connection strength between the second connecting portion 70 and the water delivery pipeline will not change with the change of the structural form of the mounting portion 20, and improving the stability of the pipeline structure under the pressure transmission state.

[0070] For a more comprehensive understanding of this solution, please refer to the attached Figure 1 , the mounting portion 20 has two opposite end faces and an outer peripheral surface 22 connecting the outer edges of the two end faces. When the second connecting portion 70 is provided on the mounting portion 20, when the first connecting portion 10 is provided on one of the end faces, the second connecting portion 70 is located on the other end face of the mounting portion 20 to avoid mutual interference in the assembled state.

[0071] Optionally, on the basis that at least part of the notch of the above material-reducing groove 30 is opened on the outer peripheral surface 22 of the material-reducing groove 30, in this embodiment, part of the notch of the material-reducing groove 30 is located on the outer peripheral surface 22 of the mounting portion 20, and the other part is located on one of the end faces of the mounting portion 20. In this way, the notch of the material-reducing groove 30 can be arranged to extend from one of the end faces of the mounting portion 20 towards the outer peripheral surface 22, so as to expand the radial extension dimension of the material-reducing groove 30 on the mounting portion 20 as much as possible.

[0072] Take the attached Figure 1Taking the first end face 21 as an example, the notch portion of the above-mentioned material reduction groove 30 is opened on the first end face 21, and the other portion is opened on the outer peripheral surface 22 of the mounting portion 20. When the pipe joint is used in the hydraulic sensor device and is installed in the valve, the first end face 21 of the mounting portion 20 is located on the upper side of the pipe joint. In this way, during the operation of the valve, the fluid in the water pipeline will enter the pressure conduit through the pipe joint. If in this case, leakage occurs between the pressure conduit and the first connection part 10, the fluid leaking from the first connector and the pressure conduit may flow to the first end face 21 of the mounting portion 20, thereby affecting the surface of the pipe joint in terms of top view and other aspects. Through the above-mentioned arrangement, the fluid located on the first end face 21 can enter the notch of the material reduction groove 30 located on the first end face 21, and further flow toward the outer peripheral surface 22 of the mounting portion 20, so that the material reduction groove 30 can play a certain exclusion function, avoid fluid leakage and long-term retention on the mounting portion 20, and play a certain protective role on the pipe joint, thereby effectively extending the service life of the pipe joint.

[0073] In one embodiment, please refer to the attached Figure 1 , the description that the mounting portion 20 has two end faces arranged opposite to each other and an outer peripheral face 22 connected to the outer edges of the two end faces, and the first connecting portion 10 is arranged on the first end face 21 of the mounting portion 20 is continued as a basis. The notch of the material reduction groove 30 in this embodiment is opened on at least one end face, and the material reduction groove 30 is arranged using the space provided by the end face of the mounting portion 20, which can provide more options for the opening method of the material reduction groove 30 on the mounting portion 20, so that the material reduction groove 30 can be reasonably selected and arranged according to different mounting portion 20 forms and other related requirements, thereby reducing the production cost of the pipe joint to a greater extent.

[0074] It can be understood from the above content that the opening of the material reduction groove 30 should minimize or even avoid the impact on the first connection part 10 and the second connection part 70 (if any) themselves, as well as the connection strength between the two and the mounting part 20 respectively. Therefore, in the case where the notch of the above-mentioned material reduction groove 30 is opened on the end face of the mounting part 20, the notch of the material reduction groove 30 is set to be spaced from the connection between the first connection part 10 (and the second connection part 70) on the mounting part 20, so as to reduce the impact of the material reduction groove 30 on the strength of the first connection part 10 and the second connection part 70.

[0075] The material reduction groove 30 in this embodiment can be attached Figure 1Taking the second groove portion 32 in the figure as a reference, the groove of the material reducing groove 30 (the second groove portion 32) is opened on the first end face 21, and the groove edge of the material reducing groove 30 is spaced from the first connecting portion 10 to ensure that there is enough connection position between the first connecting portion 10 and the first end face 21, so as to ensure that its structural strength on the mounting portion 20 can meet the use requirements of the pipe joint.

[0076] It is worth mentioning that the material reduction grooves 30 mentioned in the above two embodiments are (at least partially) opened on the first end face 21 provided with the first connecting portion 10. One of the main reasons is that the connection strength requirement between the pipe joint and the valve water supply pipeline is greater than the connection strength requirement between the pipe joint and the pressure conduit. Therefore, the size of the connection structure (second connecting portion 70) between the mounting portion 20 and the water supply pipeline is larger than that of the first connecting portion 10. Therefore, the installation space that can be provided by the second end face (not shown) of the mounting portion 20 away from its first end face 21 is relatively small. In order to reduce the influence of the material reduction groove 30 on the pipe joint and the water supply pipeline, the material reduction groove 30 is arranged on the side of the mounting portion 20 close to the first end face 21.

[0077] Please refer to the attached Figure 1 Taking the embodiment in which the material reduction groove 30 includes the first groove portion 31 and the second groove portion 32 mentioned above as an example, in this embodiment, the first groove portion 31 and the second groove portion 32 are both arranged on the mounting portion 20 along the direction surrounding the first connecting portion 10. In order to avoid mutual interference between the first groove portion 31 and the second groove portion 32, thereby affecting the structural strength of the pipe joint, the first groove portion 31 and the second groove portion 32 should be staggered in the direction surrounding the first connecting portion 10.

[0078] In one embodiment, the first groove portions 31 and the second groove portions 32 are alternately arranged along a direction surrounding the first connecting portion 10 to ensure that there are ribs between any two adjacent first groove portions 31, between any two adjacent second groove portions 32, and between any two adjacent first groove portions 31 and second groove portions 32 for ensuring the structural strength of the mounting portion 20 and the structural strength of the first connecting portion 10.

[0079] According to any of the above implementations, please refer to the attached Figure 1 A protective component 40 is also provided on the mounting portion 20. The protective component 40 is arranged at intervals on the circumferential side of the first connecting portion 10 along a direction surrounding the first connecting portion 10 to provide certain protection for the first connecting portion 10, protect the first connecting portion 10 from direct impact or scratch by external objects, prevent damage to the first connecting portion 10 and failure of the connection between the first connecting portion 10 and the pressure conduit, extend the service life of the first connecting portion 10, and also play a certain role in preventing leakage between the first connecting portion 10 and the pressure conduit.

[0080] It can be understood that, in order to avoid interference of the protection component 40 with the connection between the first connection part 10 and the pressure conduit, in this embodiment, the protection component 40 is arranged at intervals on the outer periphery of the first connection part 10, so as to form a space gap for the pressure conduit to be inserted between the protection component 40 and the first connection part 10.

[0081] It can be understood that although there are no strict limitations and requirements for the specific structural form of the protection component 40 in this embodiment, in order to enable the installation part 20 to provide more setting space for the material reduction groove 30, the protection component 40 can be set as a guard plate structure on the premise of ensuring good protection performance for the first connection part 10, so as to vacate more setting positions for the material reduction groove 30 by reducing the production material of the protection component 40.

[0082] It should be noted that an opening is formed at one end of the protection component 40 facing away from the installation part 20, so that the first connection part 10 can be exposed outside the protection component 40 through the opening, for the pressure conduit to connect with the first connection part 10 through the opening, avoiding interference of the protection component 40 with the connection between the pressure conduit and the first connection part 10, and ensuring that the pipeline joint can normally provide the pressure transmission function.

[0083] As an optional embodiment, a material reduction notch 41 is further arranged at the position where the protection component 40 is located on the circumferential side of the first connection part 10, so as to reduce the material consumed for forming the protection component 40 on the premise of protecting the first connection part 10, so as to achieve the purpose of weight reduction and cost reduction.

[0084] Optionally, on the basis that the protection component 40 is provided with the material reduction groove 30, the number of the material reduction notches 41 on the protection component 40 can be set to one or more according to actual design requirements, and in some embodiments, in order to reduce the forming difficulty of the protection component 40 and the material reduction notches 41 thereon, the material reduction notches 41 located on the protection component 40 can be set in a structural form connected to the opening.

[0085] Moreover, in the case where there are two or more material reduction notches 41 on the protection component 40, each of the material reduction notches 41 located on the protection component 40 is also set in a form spaced apart from each other along the direction around the first connection part 10, so as to ensure that the structural strength of the protection component 40 is sufficient to meet the requirement of protecting the first connection part 10. In this way, the protection component 40 will be separated by the material reduction notches 41 to form at least two surrounding plates 42 spaced apart from each other by the material reduction notch grooves.

[0086] Furthermore, when the material reduction groove 30 includes the above-mentioned first groove portion 31, and the mounting portion 20 is also provided with a protective component 40 with a material reduction notch 41, the present embodiment provides a material reduction notch 41 on the protective component 40 (located between the edges of each enclosure 42), so that part of the edge of the enclosure 42 forms the edge of the above-mentioned opening, and another part of the edge of the enclosure forms the edge of the material reduction notch 41, and the end face of the mounting portion 20 forms the bottom of the material reduction notch 41.

[0087] In the above embodiment, due to the existence of the material reduction notch 41, sufficient installation space is provided between each enclosure 42 on the end face (first end face 21) of the mounting portion 20. Therefore, the first groove portion 31 extends from the outer peripheral surface 22 of the mounting portion 20 toward the first connecting portion 10, and passes through between the two enclosures 42, so that the first groove portion 31 is at least partially located on the groove bottom of the material reduction notch 41. In addition to fully utilizing the installation space of the mounting portion 20, since the material reduction notch 41 is not directly opened on the mounting portion 20, there will be no mutual interference between the material reduction notch 41 and the first groove portion 31 that affects the structural strength of the pipe joint.

[0088] Please continue to refer to the attached Figure 1 , continuing to take the implementation method in which the mounting portion 20 is also provided with a protective component 40 as an example, when the material reduction groove 30 provided on the mounting portion 20 is a second groove portion 32, the groove opening of the second groove portion 32 is opened on the end surface of the mounting portion 20 on which the protective component 40 is provided, and the second groove portion 32 is located on the side of the protective component 40 close to the first connecting portion 10, and is arranged along the path extending from the protective component 40 on the periphery of the first connecting portion 10, staggered from the protective structure, ensuring the structural strength of the protective structure, and utilizing the space formed between the protective structure and the first connecting portion 10 to open the second groove portion 32, so as to achieve the corresponding purpose of reducing weight and reducing costs.

[0089] The above-mentioned protective component 40 is also provided with a material reduction gap 41, so that the protective part is divided into a plurality of enclosures 42. Since the enclosures 42 are not arranged to completely surround the first connecting part 10, the length dimension of the second groove portion 32 extending on the mounting portion 20 will also decrease as the size of the enclosures 42 decreases.

[0090] It can be understood that the number of the second groove portions 32 formed on the installation portion 20 can be determined according to the number of the enclosing plates 42. For example, as shown in the accompanying drawings, when the number of the enclosing plates 42 is two, the number of the second groove portions 32 is also two. The two second groove portions 32 are spaced apart on one side of the two enclosing plates 42 close to the first connecting portion 10. On the basis that the first groove portion 31 is further provided in combination with the above-mentioned installation portion 20 in this embodiment, since at least a part of the first groove portion 31 is located between the two enclosing plates 42, therefore, the manner of arranging the second groove portions 32 on the inner sides of the two enclosing plates 42 can also avoid the situation that the first groove portion 31 and the second groove portion 32 are connected and interfere with each other, meeting the requirement that the material-reducing grooves 30 are spaced apart from each other.

[0091] Please refer to the attached Figures 1-8 In addition, this embodiment further provides a valve, which includes a valve body 50 and a valve core (not shown in the figure). The specific structures of the valve body 50 and the valve core can be adaptively adjusted according to the type of the valve. This embodiment does not make strict limitations and requirements on this, and it can be but is not limited to a ball valve, a gate valve, a globe valve, a butterfly valve, etc.

[0092] In a general valve structure, a hollow valve cavity is formed inside the valve body 50. The valve body 50 further opens at least one water inlet pipe 51 and a water outlet pipe 52 communicating with the valve cavity according to the number of the passages of the valve. The water inlet pipe 51 and the water outlet pipe 52 can be understood as the water conveying pipelines mentioned in the above embodiment. And, the valve core is movably installed in the valve cavity to adjust the on-off and the opening degree of the water inlet pipe 51 and the water outlet pipe 52.

[0093] It should be noted that this valve adopts the pipeline joint as described in any of the above embodiments. The pipeline joint is arranged on the pipe wall of the water outlet pipe 52 and / or the water outlet pipe 52 through the installation portion 20, and the water outlet pipe 52 and / or the water inlet pipe 51 are provided with pipe orifices 53 for the pipeline joint to be arranged. When the pipeline joint is installed on the water outlet pipe 52 and / or the water inlet pipe 51 through the pipe orifice 53, the inside of the water inlet pipe 51 and / or the water outlet pipe 52 is communicated with the first connecting portion 10, that is, when the pipeline joint is installed on the water outlet pipe 52 and / or the water inlet pipe 51, the inside of the water outlet pipe 52 and / or the water inlet pipe 51 is communicated with the outside atmosphere through the first connecting portion 10.

[0094] On the basis of the above, this valve further includes a barometer 60 (not shown in the figure), and the barometer 60 is connected to the first connecting portion 10 through a gas guide pipe (not shown in the figure, which can also be understood as the above-mentioned pressure conduit).

[0095] Thus, when water flows from any water inlet pipe 51 through the valve cavity and out through any water outlet pipe 52, part of the water flow in at least one water pipe will enter the air guide pipe through the pipe joint. Due to the presence of air in the air guide pipe originally, the water flow entering the air guide pipe will compress the air in the air guide pipe. At this time, the water pressure is equivalent to the air pressure in the air guide pipe, allowing the air pressure to be detected by the barometer 60, so that the water pressure data in the water pipe can be obtained.

[0096] In one embodiment, the valve further includes a control box 80. As Figures 2-8 shown, a first connecting portion 82 is provided on the control box 80. Correspondingly, a second connecting portion 54 structurally adapted to the first connecting portion 82 is provided on the valve body 50. The control box 80 and the valve body 50 are installed and fitted through the first connecting portion 82 and the second connecting portion 54. The barometer 60 is disposed in the control box 80 and connected to the air guide pipe through an air pipe joint.

[0097] A transmission mechanism 83 is disposed inside the control box 80. The transmission mechanism 83 can be but is not limited to being set as a gear set. The valve core passes through the valve body 50 and has a transmission portion 55 that can rotate synchronously with the valve core. The valve core is in transmission connection with the transmission mechanism 83 through the transmission portion 55, and further, by means of arranging a driving device such as a motor 84 on the control box 80 that is in transmission connection with the transmission mechanism 83, the control box 80 is enabled to have the function of controlling the rotation of the valve core.

[0098] In one embodiment, in order to accurately collect the water pressure around each valve, an antenna 81 connected to the barometer 60 is further provided on the valve. The antenna 81 can be disposed on the control box 80 covering the outside of the valve, so that the water pressure data collected by the barometer 60 can be sent to the corresponding terminal device through the antenna 81. Moreover, the terminal device can also adjust and control the state of the valve core by sending a control signal to the corresponding valve through the antenna 81.

[0099] In addition, the present embodiment also provides an irrigation system. The irrigation system uses the valve described in the above embodiment, and the irrigation system includes all the functions of the above valve.
