Description

Technical Field

[0001] This application relates to the field of proportional valve technology, and in particular to a protocol proportional valve. Background Technology

[0002] With their high level of intelligence and integrated functions, protocol proportional valves are gradually replacing ordinary proportional valves in many fields, which has become a trend.

[0003] However, the protocol module in the protocol proportional valve has some unresolved issues. This module requires multiple PCBs to work together. When designing these PCBs, it's crucial to consider not only electrical, thermal, mechanical, and signal integrity distances, but also the spatial rationality of their structure to ensure better compatibility with the proportional valve. Therefore, the protocol proportional valve has room for further improvement. Utility Model Content

[0004] This application proposes a protocol proportional valve, which aims to improve the safety of protocol component design and optimize the spatial arrangement of protocol components.

[0005] Specifically, this protocol proportional valve uses a protocol bracket to space the three PCB boards axially. This method allows for the optimization of the safe design distances between the PCB boards and the adjustment of spatial rationality, thus facilitating their compatibility with the proportional valve.

[0006] The protocol proportional valve provided in this application adopts the following technical solution:

[0007] A protocol proportional valve includes a protocol component, which includes a protocol support, a first PCB board, a second PCB board, and a third PCB board, wherein the first PCB board, the second PCB board, and the third PCB board are spaced apart on the protocol support along an axial direction.

[0008] By adopting the above technical solution, the overall volume of a conventional proportional valve is generally small. Therefore, considering the volume of the conventional proportional valve and the area of ​​the PCB board required for the overall protocol module, a hierarchical arrangement of the PCB board is adopted. At the same time, three PCB boards are used according to the volume of the conventional proportional valve. The staff installs the first, second, and third PCB boards on the protocol bracket at intervals along the axial direction. This not only limits the installation position of the first, second, and third PCB boards by the protocol bracket, but also ensures that the first, second, and third PCB boards have at least a minimum electrical safety distance from each other. In addition, the axial spacing allows the protocol components to have a regular and effective spatial arrangement, thereby making the structure of the protocol proportional valve reasonable.

[0009] Preferably, the protocol bracket includes a bracket body, an upper support leg, and a lower support leg. The bracket body has an axial through hole. One end of the bracket body is connected to the upper support leg, and the other end is connected to the lower support leg. The first PCB board is connected to the end of the upper support leg away from the bracket body. The second PCB board is inserted into the upper support leg, and the third PCB board is inserted into the lower support leg.

[0010] By adopting the above technical solution, the user first inserts the third PCB board into the lower support of the protocol bracket, then inserts the second PCB board into the upper support of the protocol bracket, and then places the first PCB board on the upper end of the upper support of the protocol bracket. The protocol bracket axially divides the first, second, and third PCB boards into three levels, and also separates the protocol bracket from other structures below through the lower support, so that the PCB boards of the protocol components have sufficient space, ensuring electrical safety distance and optimizing the spatial arrangement of the protocol components.

[0011] Preferably, the second PCB board is located at one end face of the bracket body, the third PCB board is located at the other end face of the bracket body, and the bracket body has grooves on its two end faces.

[0012] By adopting the above technical solution, the second PCB board and the third PCB board are arranged close to each other on the bracket body. This makes the second PCB board not only limited by the position of the upper and lower support feet, but also by the position of the bracket body. This improves the stability of the installation of the second PCB board and the third PCB board. In addition, the groove allows air to circulate between the bracket body, the first PCB board and the second PCB board, which facilitates the heat dissipation of the PCB board.

[0013] Preferably, the bracket body includes a plate portion and a corner portion, the plate portion and the corner portion are connected alternately to form a hollow "+" shape, the upper support is located at the corner portion, and the second PCB board has a notch corresponding to the position of the corner portion, the second PCB board is located between the four upper support legs through the notch.

[0014] By adopting the above technical solution, after the third PCB board is installed, the second PCB board can be placed between the four upper support legs, allowing the second PCB board to slide down quickly for assembly, thus making the installation efficiency of the second PCB board higher.

[0015] Preferably, the lower support includes a cylindrical foot and a semi-circular foot. One end of the third PCB board has an elongated groove, and the other end has a semi-circular groove. The cylindrical foot is located in the elongated groove, and the semi-circular foot mates with the semi-circular groove.

[0016] By adopting the above technical solution, during installation, the staff first inserts the elongated groove at one end of the third PCB board into the cylindrical foot, and then mates the semi-circular groove at the other end of the third PCB board with the slightly deformed semi-circular foot. This allows for quick assembly. The elongated groove prevents the cylindrical foot from easily disengaging, while the semi-circular groove and semi-circular foot are easier to match. Moreover, the assembly after elastic deformation will press against each other and will not easily disengage. This makes the third PCB board not only highly efficient in assembly but also highly stable in assembly.

[0017] Preferably, it also includes a solenoid valve assembly, which has a slot that mates with the lower support leg.

[0018] By adopting the above technical solution, the protocol component is located on the solenoid valve assembly, and the lower support of the protocol component is inserted into the slot of the solenoid valve assembly. This not only ensures a stable connection between the protocol component and the solenoid valve assembly, but also ensures a safe distance between them. This effectively guarantees an electrical safety distance between the circuit board inside the solenoid valve assembly and the third PCB board, resulting in a better spatial layout for the protocol proportional valve.

[0019] Preferably, the solenoid valve assembly is further provided with a protrusion, which abuts against one end of the semi-circular groove of the third PCB board.

[0020] By adopting the above technical solution, since the assembly of the semi-circular groove and the semi-circular foot is easier than the detachment of the elongated groove and the cylindrical foot, the detachment of the third PCB board and the lower support will start from the semi-circular groove and the semi-circular foot. By using the protrusion on the solenoid valve assembly to hold the end of the third PCB board near the semi-circular groove, the detachment of the semi-circular groove and the semi-circular foot of the third PCB board can be effectively prevented.

[0021] Preferably, it also includes a valve assembly and a solenoid valve assembly, wherein one end of the solenoid valve assembly is connected to the valve assembly and the other end is connected to the protocol assembly.

[0022] By adopting the above technical solution, the valve assembly, solenoid valve assembly and protocol assembly are arranged in layers, which makes the structure clear, and the protocol proportional valve occupies less space and is relatively regular in shape.

[0023] Preferably, the protocol component further includes a protocol port located on the first PCB board.

[0024] By adopting the above technical solution, the end of the protocol proportional valve can be connected to a protocol socket, which facilitates the connection of the protocol proportional valve with other components.

[0025] Preferably, the assembly also includes a housing, the inner end of which is provided with a housing protrusion. The housing is connected to the valve assembly, and the first PCB board is located inside the housing, with the housing protrusion abutting against the first PCB board.

[0026] By adopting the above technical solution, the housing covers the protocol component and the solenoid valve component, so that the first PCB board can not only be connected and plugged in with the upper support through conventional screws, but also the upper support can squeeze the first PCB board from bottom to top and the housing protrusion can squeeze the first PCB board from top to bottom for positioning. At the same time, the housing also has the function of beautifying the appearance of the protocol proportional valve.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. Generally speaking, conventional proportional valves have a relatively small overall volume. Considering the volume of conventional proportional valves and the area of ​​the PCB board required for the overall protocol module, a hierarchical arrangement of the PCB board is adopted. At the same time, three PCB boards are used according to the volume of conventional proportional valves. The staff installs the first PCB board, the second PCB board, and the third PCB board on the protocol bracket at intervals along the axial direction. This not only limits the installation position of the first PCB board, the second PCB board, and the third PCB board through the protocol bracket, but also ensures that the first PCB board, the second PCB board, and the third PCB board have at least a minimum electrical safety distance from each other. At the same time, the axial spacing allows the protocol components to have a regular and effective spatial arrangement, thereby making the structure of the protocol proportional valve reasonable.

[0029] 2. The user first inserts the third PCB board into the lower support of the protocol bracket, then inserts the second PCB board into the upper support of the protocol bracket, and then places the first PCB board on the upper end of the upper support of the protocol bracket. The protocol bracket axially divides the first, second, and third PCB boards into three levels, and also separates the protocol bracket from other structures below through the lower support, so that the PCB boards of the protocol components have sufficient space, ensuring electrical safety distance and optimizing the spatial arrangement of the protocol components.

[0030] 3. During installation, the staff first inserts the elongated groove at one end of the third PCB board into the cylindrical foot, and then mates the semi-circular groove at the other end of the third PCB board with the slightly deformed semi-circular foot. This allows for quick assembly. The elongated groove prevents the cylindrical foot from easily detaching, while the semi-circular groove and semi-circular foot are easier to match. Moreover, the elastically deformed fit will cause the assembly to press against each other, preventing easy detachment. This makes the third PCB board not only highly efficient to assemble but also has strong assembly stability. Attached Figure Description

[0037] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0038] This application discloses a protocol proportional valve.

[0039] Reference Figures 1-5 From top to bottom, the assembly includes a protocol component 1, a valve component 3, a solenoid valve component 2, and a housing 4. One end of the valve component 3 is connected to the protocol component 1, and the other end is connected to the solenoid valve component 2. The housing 4 is bolted to the solenoid valve component 2 and covers the valve component 3 and part of the protocol component 1, resulting in a layered arrangement of the valve component 3, solenoid valve component 2, and protocol component 1. This makes the structure clear, and the protocol proportional valve occupies a small space and is a relatively regular elongated shape. (The connection method of the valve component 3 and the solenoid valve component 2 is common in the prior art, and their specific structure will not be described here.)

[0040] Protocol component 1 includes a protocol bracket 11, a first PCB board 12, a second PCB board 13, a third PCB board 14, and a protocol socket 15. The protocol bracket 11 includes a bracket body 111, an upper support leg 112, and a lower support leg 113. The bracket body 111 has an axial through hole 1111. One end of the bracket body 111 is integrally formed with the upper support leg 112, and the other end is integrally formed with the lower support leg 113. The third PCB board 14 is inserted into the lower support leg 113, the second PCB board 13 is inserted into the upper support leg 112, and the first PCB board 12 abuts against the upper end of the upper support leg 112. The protocol socket 15 is electrically connected to the upper side of the first PCB board 12, and the first PCB board 12, the second PCB board 13, and the third PCB board 14 are also electrically connected to each other, so that the first PCB board 12, the second PCB board 13, and the third PCB board 14 are spaced apart on the protocol bracket 11 in the axial direction.

[0041] Generally, conventional proportional valves are relatively small in size. Therefore, considering the volume of the conventional proportional valve and the area of ​​the PCB board required for the overall protocol module, a hierarchical arrangement of the PCB board is adopted. Three PCB boards are used based on the volume of the conventional proportional valve. The operator first inserts the third PCB board 14 into the lower support 113 of the protocol bracket 11, then inserts the second PCB board 13 into the upper support 112 of the protocol bracket 11. Then, the first PCB board 12 is placed on the upper support 112 of the protocol bracket 11. Because there are wiring connections between the three PCB boards, the first PCB board 12 will not fall off after being placed on the upper support 112. The protocol bracket 11 holds the first PCB board 12, the second PCB board 13, and the third PCB board 14 together. The PCB board 13 and the third PCB board 14 are axially spaced in three layers, ensuring that the first PCB board 12, the second PCB board 13, and the third PCB board 14 have at least a minimum electrical safety distance from each other. At the same time, the axial spacing allows the protocol component 1 to have a regular and effective spatial arrangement, thereby making the structure of the protocol proportional valve reasonable. Furthermore, the lower support 113 of the protocol component 1 is inserted into the slot 21 of the solenoid valve component 2, which not only ensures a stable connection between the protocol component 1 and the solenoid valve component 2, but also ensures a safe distance between the protocol component 1 and the solenoid valve component 2. This effectively guarantees an electrical safety distance between the circuit board inside the solenoid valve component 2 and the third PCB board 14, resulting in a more optimal spatial layout for the protocol proportional valve.

[0042] The upper end of the housing 4 has a through hole for the protocol socket 15 to pass through. The inner end of the upper side of the housing 4 also has an integrally formed housing protrusion, so that when the housing 4 is fitted with the protocol component 1, the protocol socket 15 of the protocol component 1 can protrude through the through hole. Therefore, the end of the protocol proportional valve can be connected to the protocol socket 15, which facilitates the connection of the protocol proportional valve with other components. Then the housing 4 gradually covers the protocol component 1 and the solenoid valve component 2. The housing protrusion at the inner end of the housing 4 abuts against the first PCB board 12, so that the first PCB board 12 can not only be connected with the upper support 112 by conventional screws, plugs, etc., but also be limited by the upper support 112 pressing the first PCB board 12 from bottom to top and the housing protrusion pressing the first PCB board 12 from top to bottom. At the same time, the housing 4 also has the function of beautifying the appearance of the protocol proportional valve.

[0043] Furthermore, in this embodiment, the second PCB board 13 is inserted into and located at the upper end face of the bracket body 111, and the third PCB board 14 is inserted into and located at the lower end face of the bracket body 111. The bracket body 111 has grooves 1114 on its end faces at both ends, so that the second PCB board 13 and the third PCB board 14 are arranged close to each other on the bracket body 111. The second PCB board 13 is not only limited by the positions of the upper support 112 and the lower support 113, but also by the position of the bracket body 111, thereby improving the stability of the installation of the second PCB board 13 and the third PCB board 14. In addition, the grooves 1114 allow air to circulate between the bracket body 111, the first PCB board 12, and the second PCB board 13, which facilitates the heat dissipation of the PCB boards.

[0044] Furthermore, in this embodiment, the bracket body 111 includes a plate portion 1112 and a corner portion 1113. The plate portion 1112 and the corner portion 1113 are integrally formed alternately to form a hollow "+" shape. The upper support 112 is located at the corner portion 1113. The second PCB board 13 has a notch 131 corresponding to the position of the corner portion 1113, so that after the worker installs the third PCB board 14, the second PCB board 13 is placed between the four upper support 112, so that the second PCB board 13 slides down quickly under the action of gravity and is limited by the four upper support 112, so that the installation efficiency of the second PCB board 13 is high.

[0045] Furthermore, in this embodiment, the lower support 113 includes a cylindrical foot 1131 and a semi-circular foot 1132. The third PCB board 14 has two symmetrical elongated grooves 141 at one end and a semi-circular groove 142 in the middle of the other end, so that the lower support 113 is arranged in a triangle. In the lower support 113, the cylindrical foot 1131 cooperates with the elongated groove 141, and the semi-circular foot 1132 cooperates with the semi-circular groove 142.

[0046] During installation, the workers first insert the elongated groove 141 at one end of the third PCB board 14 into the cylindrical foot 1131. Then, the semicircular groove 142 at the other end of the third PCB board 14 is matched with the slightly deformable semicircular foot 1132 for quick assembly. The elongated groove 141 prevents the cylindrical foot 1131 from easily disengaging, while the semicircular groove 142 and the semicircular foot 1132 are easy to match. Moreover, the semicircular foot 1132, after elastic deformation, will press against each other and will not easily disengage. This makes the third PCB board 14 not only highly efficient in assembly but also highly stable in assembly.

[0047] Furthermore, in this embodiment, the upper end of the solenoid valve assembly 2 also has a protrusion 22, which abuts against one end of the third PCB board 14 near the semi-circular groove 142. Since the assembly of the semi-circular groove 142 and the semi-circular foot 1132 is easier than the detachment of the elongated groove 141 and the cylindrical foot 1131, the detachment of the third PCB board 14 and the lower support 113 will first start from the semi-circular groove 142 and the semi-circular foot 1132. By abutting against one end of the third PCB board 14 near the semi-circular groove 142 by the protrusion 22 on the solenoid valve assembly 2, the detachment of the semi-circular groove 142 and the semi-circular foot 1132 of the third PCB board 14 can be effectively prevented.

[0048] Furthermore, in this embodiment, the present invention does not impose any particular restrictions on the specific connection structure between the PCB board and the protocol bracket 11. Any connection structure known to those skilled in the art that enables the PCB board to be spaced apart along the axial direction on the protocol bracket 11 can be used. Those skilled in the art can select and adjust the connection structure according to the specific application and product requirements.

[0049] It should be noted that the various embodiments of this application can be arbitrarily combined into new embodiments, provided that the solutions do not conflict and the technical solutions can coexist.

[0050] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
