Description

Technical Field

[0001] This utility model relates to the field of valve technology, and more specifically, to a control valve. Background Technology

[0002] Figure 1 This is a schematic diagram of a control valve in the background art. The control valve includes a valve body component 1' and a mounting plate 4'. The valve body component 1' includes an inlet 2' and an outlet 3'. When the control valve is installed in a refrigeration system, at least one of the inlet 2' and outlet 3' needs to be connected and fixed to the refrigeration system piping. The mounting plate 4' is connected to the valve body component 1'. However, during use in the refrigeration system, the valve body component 1' is still prone to vibration and swaying due to the impact force generated by fluid flow and frequent changes in pressure within the piping, thereby affecting the stability of the overall piping system. Therefore, how to improve the stability of the control valve and the overall piping system is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0011] The embodiments of this application will be further described below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0012] Figure 2 A three-dimensional schematic diagram of the control valve provided by this utility model; Figure 3 for Figure 2 Front view of the control valve in the image; Figure 4 for Figure 2 A three-dimensional schematic diagram of the support structure; Figure 5 for Figure 4 Front view of the bracket in the middle; Figure 6 for Figure 4 Top view of the bracket in the middle.

[0013] It should be noted that, with Figure 2 For example, the lateral direction of the control valve shown in the figure is the axial direction of the control valve, which is also the axial direction of the valve body 21 described below, and the longitudinal direction of the control valve is the thickness direction of the frame part 11 described below.

[0014] In this embodiment, a ball valve is used as an example to illustrate the control valve. The control valve includes a control valve body 2, which includes a valve body 21, a first connecting pipe 22, and a second connecting pipe 23. Along the axial direction of the control valve, the first connecting pipe 22 and the second connecting pipe 23 are located on opposite sides of the valve body 21. The first connecting pipe 22 is directly or indirectly connected to the valve body 21, and the second connecting pipe 23 is also directly or indirectly connected to the valve body 21. The first connecting pipe 22 includes an inlet end on the side away from the valve body 21, which is welded and fixed to a pipe in the refrigeration system. The second connecting pipe 23 includes an outlet end on the side away from the valve body 21, which is either welded and fixed to a pipe in the refrigeration system or not connected to a pipe in the refrigeration system. This control valve controls whether the refrigeration system flows at that location.

[0015] In this embodiment, the control valve body 2 also includes a first bushing 24 and a second bushing 25. The first bushing 24 connects the first connecting pipe 22 to the valve body 21, and the second bushing 25 connects the second connecting pipe 23 to the valve body 21, which facilitates the processing and manufacturing of the control valve body 2.

[0016] Among them, the valve body 21, the first connecting pipe 22, the second connecting pipe 23, the first bushing 24 and the second bushing 25 are made of stainless steel. After being made of stainless steel, the control valve has the characteristics of being lead-free, small in size and light in weight, which can reduce the weight of the control valve body 2 and the processing and manufacturing cost.

[0017] like Figure 2-6 As shown, the control valve in this embodiment also includes a bracket 1. The bracket 1 includes a frame portion 11 and a connecting portion 12. In the longitudinal direction of the control valve, the frame portion 11 is located below the control valve body 2. The frame portion 11 is plate-shaped. The connecting portion 12 includes a first support portion 121 and a second support portion 122. In the axial direction of the control valve, the first support portion 121 and the second support portion 122 are located on both sides of the frame portion 11. The first support portion 121 includes a first upper connecting end 1210 and a first lower connecting end 1211. The first upper connecting end 1210 is fixedly connected to the control valve body 2, and the first lower connecting end 1211 is connected to the frame portion 11. The second support portion 122 includes a second upper connecting end 1220 and a second lower connecting end 1221. The second upper connecting end 1220 is fixedly connected to the control valve body 2, and the second lower connecting end 1221 is connected to the frame portion 11. In this embodiment, the control valve has a plate-shaped frame 11 of the bracket 1. The first support 121 and the second support 122 of the bracket are located on both sides of the frame. The first support 121 and the second support 122 jointly support the control valve body 2. When the control valve body 2 is subjected to pressure or external impact, the frame 11 and the support share the load, thereby improving the stability of the control valve body 2 in the refrigeration system and ensuring the stability of the refrigeration system pipeline.

[0018] like Figure 3-4 As shown, the first support portion 121 and the second support portion 122 are located on both sides of the frame portion 11, forming a symmetrical structure. This symmetrical arrangement allows the force on the valve body 21 to be more evenly distributed across the first support portion 121 and the second support portion 122, thereby improving the stability of the control valve in the refrigeration system piping. When the control valve body 2 is subjected to significant pressure or external impact, the first support portion 121 and the second support portion 122 can share the load, effectively reducing the deformation and displacement of the valve body 21 and ensuring the normal operation of the refrigeration system.

[0019] It should also be noted that the first support 121 and the second support 122 can better distribute the weight and external force of the control valve body 2, making the stress distribution more uniform and reducing the phenomenon of local stress concentration, which helps to improve the reliability of the control valve body 2.

[0020] At the same time, such as Figure 5As shown, the frame 11 is connected to the mounting base (not shown) in the refrigeration system. The frame 11 can more evenly distribute the weight of the control valve body 2 and the pressure generated during operation, effectively reducing the risk of deformation or damage caused by local stress concentration, providing a more stable support base for the control valve body 2, and ensuring that it can maintain stable structural integrity under various working conditions.

[0021] Regarding the support portion of bracket 1 used to cooperate with the mounting base, specifically, the bracket body 11 includes a support surface 110 on the side away from the control valve body 2, the support surface 110 faces the mounting base, the support surface 110 is a plane, and the support surface 110 is used to contact the surface of the mounting base.

[0022] like Figure 4 As shown, the frame 11 is plate-shaped and includes a plate portion 111, a first mounting portion 112, and a second mounting portion 113. In the axial direction of the control valve, the first support portion 121 and the second support portion 122 are located on both sides of the plate portion 111, respectively. In the radial direction of the control valve, the plate portion 111 is located between the first mounting portion 112 and the second mounting portion 113. Through the first mounting portion 112 and the second mounting portion 113, on the one hand, the lateral impact forces generated by fluid flow on the control valve body 2 can be further effectively absorbed and dispersed. Since the mounting portion and the plate portion 111 are an integral plate structure, these forces can be evenly transmitted to the entire mounting bracket, reducing the risk of deformation or damage caused by excessive local stress and improving the lateral stability of the entire support structure. On the other hand, the frame 11 can have a better vibration damping effect, maintaining the operation of the control valve body 2 in a stable state and ensuring the stability of the refrigeration system piping.

[0023] Meanwhile, the first mounting portion 112 includes a first connecting hole 1120, which extends through the first mounting portion 112 in the longitudinal direction of the control valve. The second mounting portion 113 includes a second connecting hole 1130, which extends through the second mounting portion 113 in the longitudinal direction of the control valve. The first connecting hole 1120 and the second connecting hole 1130 are used to cooperate with connecting parts to achieve the connection and fixation between the bracket 1 and the mounting base, ensuring the stability and reliability of the control valve body 2 during use. Of course, bolts or screws are preferably used as the connecting parts.

[0024] Combination Figure 4 As shown, since the first mounting part 112 and the second mounting part 113 are located on both sides of the plate part 111 in the radial direction of the control valve, that is, the first connecting hole part 1120 and the second connecting hole part 1130 are located on the outside of the connecting part 12, it is easy to operate when the bracket 1 is fixed by bolts or screws, which helps to improve work efficiency.

[0025] like Figure 4 As shown, the first mounting portion 112 includes a first reinforcing portion 1121, which is located above the first mounting portion 112. A first connecting hole portion 1120 is a threaded hole or a straight hole, extending through the first mounting portion 112 and the first reinforcing portion 1121 in the longitudinal direction of the control valve. The second mounting portion 113 includes a second reinforcing portion 1131, which is located above the second mounting portion 113. A second connecting hole portion 1130 is a threaded hole or a straight hole, extending through the second mounting portion 113 and the second reinforcing portion 1131 in the longitudinal direction of the control valve. Thus, the reinforcing portion increases the mating dimension with the aforementioned connector in the thickness direction of the frame portion 11, making the connection between the connector and the frame portion 11 more stable and improving the stability of the control valve body 2 in the refrigeration system.

[0026] In this embodiment, the bracket 1 is a stamped plate, and the first reinforcing part 1121 and the second reinforcing part 1131 are formed by reverse punching and flanging during the processing of the plate using a mold.

[0027] In this embodiment, the frame portion 11 and the connecting portion 12 are an integral structure. Specifically, the first support portion 121 includes a first bent portion 1212, which serves as a first lower connecting end 1211. The first bent portion 1212 bends upward from the first side of the frame portion 11. The second support portion 122 includes a second bent portion 1222, which serves as a second lower connecting end 1221. The first bent portion 1212 bends upward from the second side of the frame portion 11. This ensures the connection strength between the frame portion 11 and the connecting portion 12, making it less prone to loosening or breakage of the connection when subjected to large external forces.

[0028] like Figure 6 As shown, the first mounting portion 112 includes a first expansion portion 1122, the width of which is greater than the width of the plate portion 111 (defined as L4 for the width of the first expansion portion 1122 and L5 for the width of the plate portion 111, i.e., L4 > L5). A first gap exists between the first expansion portion 1122 and the connecting portion 12 in the radial direction of the control valve, defined as X1. The second mounting portion 113 includes a second expansion portion 1132, the length of which is greater than the length of the plate portion 111 (defined as L6 for the width of the second expansion portion 1132 and L5 for the width of the plate portion 111, i.e., L6 > L5). A first gap exists between the first expansion portion 1122 and the connecting portion 12 in the radial direction of the control valve, defined as X1. A second gap exists between the second expansion portion 1132 and the connecting portion 12 in the radial direction of the control valve, defined as X2. Before bending the connecting part 12, the first gap and the second gap are reserved to facilitate the processing of the connecting part 12 during bending.

[0029] In this embodiment, the bracket 1 is made of stainless steel sheet, formed by stamping and bending, and the thickness of the frame body 11 and the connecting part 12 are relatively consistent. Specifically, the first support part 121 is plate-shaped and extends from the frame body 11 along the longitudinal direction of the control valve, that is, in the case of... Figure 3 From the perspective of the frame 11, the first support 121 is vertically arranged relative to the frame 11; the second support 122 is plate-shaped and extends longitudinally from the frame 11 along the control valve, that is, in the case of... Figure 3 From this perspective, the second support portion 122 is vertically arranged relative to the frame portion 11 to ensure the stability of the bracket 1. In this embodiment, the thickness of the bracket 1 is 1-2.5mm, preferably 1.5mm.

[0030] like Figure 2-3 As shown, the valve body 21 is cylindrical. The first support part 121 includes a first arc surface, which serves as the first upper connecting end 1210. The first upper connecting end 1210 is in contact with the outer surface of the valve body 21. The second support part 122 includes a second arc surface, which serves as the second upper connecting end 1220. The second upper connecting end 1220 is in contact with the outer surface of the valve body 21. This increases the contact area between the bracket 1 and the outer surface of the valve body 21, thereby ensuring the stability of the control valve body 2.

[0031] Here, the outer diameter of the valve body 21 is defined as D, and the length of the first upper connecting end 1210 is L3, satisfying 0.5D≤L3≤D. This provides a more stable support foundation for the control valve body 2, ensuring its stability under various operating conditions.

[0032] The first support part 121 is fixed to the outer surface of the valve body 21 by laser welding, and the second support part 122 is also fixed to the outer surface of the valve body 21 by laser welding.

[0033] In this embodiment, the length of the first lower connecting end 1211 is greater than the length of the first upper connecting end 1210, and the length of the second lower connecting end 1221 is greater than the length of the second upper connecting end 1220. This helps to ensure the stability of the bracket 1 on the control valve body 2.

[0034] like Figure 2-3 As shown, in the axial direction of the control valve, the distance between the first support 121 and the second support 122 is defined as L1, and the length of the valve body 21 is L2. This satisfies 3L2 / 10 ≤ L1 ≤ 3L2 / 4. This helps improve the stability of the control valve body 2 in the refrigeration system.

[0035] In this embodiment, the control valve body 2 includes a valve body 21, with the centerline of the valve body 21 defined as C. Along the axial direction of the control valve, the first support portion 121 and the second support portion 122 are located on either side of the centerline. Therefore, the bracket 1 can provide a stable support point for the control valve body 2, effectively resisting the impact force generated by fluid flow and the force transmitted from the pressure within the pipes during refrigeration system operation, thus reducing the vibration and swaying of the control valve body 2.

[0036] The above examples illustrate the principles and implementation methods of this application. The descriptions of the embodiments are merely for the purpose of helping to understand the technical solutions and core ideas of this application. It should be noted that those skilled in the art can make various improvements and modifications to this application without departing from its principles, and these improvements and modifications also fall within the protection scope of this application.
