Description

Technical Field

[0001] This application relates to the technical field of valves, and particularly to an installation structure of a ball valve. Background Art

[0002] A ball valve is an important type of valve used to control the connection or disconnection of pipelines, thereby changing the flow direction of fluids. Its working principle is to control and regulate fluids by rotating a sphere within the valve body.

[0003] When existing ball valves are connected to pipelines, they are usually not additionally fixed. When the pipeline is subjected to vibration or shaking, the ball valve will shake or vibrate, resulting in poor structural stability of the ball valve. In some current requirements, it is necessary to install the ball valve at the installation position to be installed, but the existing technology does not provide a relevant structure to solve the above technical problems. Summary of the Utility Model

[0004] Based on this, it is necessary to provide an installation structure of a ball valve to reduce the probability of vibration or shaking of the ball valve by reliably fixing the valve body of the ball valve.

[0005] This application provides an installation structure for fixing the valve body of a ball valve. The installation structure includes a connecting plate for fixedly connecting to the outer peripheral surface of the valve body and an installation member for connecting the connecting plate to the installation position to be installed. The area where the outer peripheral surface of the valve body is connected to the connecting plate is defined as the connection area, and the connecting plate has a fitting surface for fitting with the connection area.

[0006] In one embodiment, the connecting plate is fixed to the connection area by welding.

[0007] In one embodiment, the connecting plate is provided with a through hole for accommodating welding materials at a position corresponding to the fitting surface, and the through hole penetrates the connecting plate along the thickness direction of the connecting plate.

[0008] It can be understood that the existence of the through hole is for solder or solder paste to thoroughly penetrate between the fitting surface and the connection area. Then, the joint surface between the fitting surface and the connection area is completely filled and covered with solder, enabling the valve body and the connecting plate to be connected together. That is, the existence of the through hole can increase the effective welding area between the fitting surface of the connecting plate and the connection area of the valve body, ensure that the solder is filled as much as possible at the joint surface between the two, improve the welding effect, and further improve the reliability of the fixation of the connecting plate and the valve body.

[0009] In one embodiment, the through hole is located at the center position of the fitting surface.

[0010] In one embodiment, the welding method is furnace brazing, or a combined welding method of laser spot welding and furnace brazing.

[0011] It can be understood that the above-mentioned laser spot welding is to pre-fix the position first to facilitate subsequent direct furnace welding.

[0012] In addition, in another embodiment, the valve body can also adopt a spherical shape or other shapes.

[0013] In one embodiment, the connecting plate is substantially U-shaped and includes two oppositely arranged side plates and an intermediate plate located between the two side plates. The fitting surface is located on the intermediate plate. The side plates extend towards the direction away from the fitting surface of the intermediate plate, and the mounting member is connected to the side plates.

[0014] In one embodiment, at least a part of the intermediate plate protrudes towards the direction away from the valve body, thereby forming a groove with an opening facing the valve body, and the wall surface of the groove is the fitting surface.

[0015] In one embodiment, the direction of the line connecting the parts where the two side plates are connected to the intermediate plate is defined as the first direction, and the two side plates are arranged at intervals along the first direction. The mounting member is a mounting plate extending along the first direction, and each side plate is correspondingly connected with one mounting plate.

[0016] In one embodiment, the valve body is cylindrical, and both the fitting surface and the connection area are arc surfaces. The axial direction of the valve body is defined as the second direction, and the second direction is perpendicular or substantially perpendicular to the first direction.

[0017] In one embodiment, both of the two mounting plates extend away from each other from the connection with the side plates.

[0018] In one embodiment, the side edge of the side plate away from the intermediate plate is fixedly connected to the side edge of the corresponding mounting plate.

[0019] In one embodiment, the side plate, the intermediate plate and the mounting plate are integrally formed parts.

[0020] Compared with the prior art, the installation structure of the ball valve provided in this application realizes the connection between the valve body of the ball valve and the installation position to be installed. The connecting plate in the installation structure is fixedly connected to and fits with the outer peripheral surface of the valve body, that is, the outer peripheral surface of the valve body fits with the fitting surface of the connecting plate. By adopting the surface-to-surface contact method, the connection stability between the valve body and the connecting plate is improved. The installation part of the installation structure connects the valve body and the installation position to be installed, and the ball valve can be installed at the specified installation position to be installed. The entire installation structure reduces the possibility of the ball valve shaking or vibrating, avoids loosening or structural deformation caused by vibration or shaking in the pipeline, and improves the reliability of installation.

[0032] Please refer to Figures 1 to 4 , in order to reduce the probability of the ball valve shaking or vibrating and improve the stability of the ball valve, this application provides an installation structure for the ball valve. This installation structure is used to fix the valve body 1 of the ball valve. In one embodiment, the valve body 1 of the ball valve is cylindrical.

[0033] As Figures 1~4As shown in the figure, the above installation structure includes a connecting plate 2 and a mounting member 3. Among them, the connecting plate 2 is used to fixedly connect with the outer peripheral surface of the valve body 1. The area where the outer peripheral surface of the valve body 1 is connected to the connecting plate 2 is defined as the connection area 11, and the connecting plate 2 has a fitting surface 221 for fitting with the connection area 11. In addition, since the valve body 1 is cylindrical, both the fitting surface 221 and the connection area 11 are arc surfaces.

[0034] As Figure 2 and Figure 3 shown in the figure, the connecting plate 2 is fixed on the connection area 11 by welding, and a through hole 222 for accommodating welding materials is provided on the connecting plate 2. The through hole 222 is located on the fitting surface 221 and penetrates the connecting plate 2 along the thickness direction of the connecting plate 2. The above welding materials are solder or solder paste, etc. In one embodiment, the welding method is furnace brazing. In another embodiment, the welding method is a combined welding method of laser spot welding and furnace brazing.

[0035] It can be understood that laser spot welding is used to pre-fix the position first, which is convenient for subsequent direct furnace welding. The existence of the through hole 222 adds a position for accommodating welding materials, so that the solder or solder paste can thoroughly penetrate between the fitting surface 221 and the connection area 11. Then, the joint surface between the fitting surface 221 and the connection area 11 is completely filled and covered with solder, which can connect the valve body and the connecting plate together. That is to say, the existence of the through hole 222 can increase the effective welding area between the fitting surface 221 of the connecting plate 2 and the connection area 11 of the valve body 1, ensure that the solder is filled as much as possible at the joint surface of the two, improve the welding effect, and further improve the reliability of the fixation of the connecting plate 2 and the valve body 1. It avoids the problem that the edge of the fitting surface 221 and the connection area 11 is welded, and the melted solder cannot penetrate inward, resulting in the detachment of the connecting plate during use.

[0036] In one embodiment, the through hole 222 is located at the center position of the fitting surface 221. It can be understood that the above setting enables the solder to be better filled between the outer peripheral surface of the valve body 1 and the fitting surface 221, and better improves the welding effect.

[0037] The above through hole 222 can adopt any shape, such as a square hole, a circular hole, an oval hole, etc.

[0038] As Figures 2 to 4As shown, the connecting plate 2 is basically U-shaped and includes two oppositely arranged side plates 21 and an intermediate plate 22 located between the two side plates 21. The intermediate plate 22 is smoothly and transitionally connected to the side plates 21. The two side plates 21 are arranged at intervals along the first direction X, the axial direction of the valve body 1 is the second direction Y, and the first direction X and the second direction Y are perpendicular or substantially perpendicular to each other. The above-mentioned joint surface 221 is located on the intermediate plate 22. The side plates 21 extend in the direction away from the joint surface 221 of the intermediate plate 22, and this direction is defined as the third direction Z, that is, the side plates 21 extend along the third direction Z. It should be noted that "substantially perpendicular" includes but is not limited to being completely perpendicular, and there can be small deviations.

[0039] In one embodiment, at least part of the above-mentioned intermediate plate 22 protrudes in the direction away from the valve body 1, so as to form a groove 220 with an opening facing the valve body 1, that is, the opening faces the opposite direction of the third direction Z. The wall surface of the groove 220 is the joint surface 221. In addition, in one embodiment, the above-mentioned joint surface 221 can also be directly formed on the wall surface of the intermediate plate 22 facing the valve body 1.

[0040] The mounting member 3 is connected to the side plate 21 and is used to connect the connecting plate 2 to the position to be installed. As Figures 2~4 shown, the mounting member 3 is a mounting plate extending along the above-mentioned first direction X. Each of the above-mentioned side plates 21 is correspondingly connected with a mounting plate. The part where the side plate 21 is connected to the mounting plate is the connection part, and the two mounting plates both extend away from each other from the connection part, that is, the connecting plate 2 is located between the two mounting plates. The connection methods of the two side plates 21 and the corresponding mounting plates on the corresponding sides are the same. Specifically, the side edge of the side plate 21 away from the intermediate plate 22 is fixedly connected to the side edge of the corresponding mounting plate, and the side plate 21 and the mounting plate are smoothly and transitionally connected. In one embodiment, the side plate 21 is integrally formed on the side edge of the intermediate plate 22. In another embodiment, the side plate 21, the intermediate plate 22 and the mounting plate are integrally formed parts.

[0041] In one embodiment of the connection method between the above-mentioned mounting plate and the position to be installed, the mounting plate and the position to be installed are correspondingly provided with mounting holes 31 for the connecting member to be constrained therein. In another embodiment, a clamp can also be used to realize the connection between the mounting plate and the position to be installed.

[0042] The above-mentioned mounting structure realizes the connection between the valve body 1 of the ball valve and the position to be installed. The joint surface 221 of the connecting plate 2 is in contact with the connection area 11 of the outer peripheral surface of the valve body 1, and the surface-to-surface contact method is adopted, which improves the connection stability between the valve body and the connecting plate. The two mounting plates of the mounting structure install the ball valve at the designated position to be installed, increasing the reliability of the ball valve installation. After the ball valve is installed through the above-mentioned mounting structure, it is more reliable, reducing the possibility of the ball valve shaking or vibrating, and avoiding loosening or structural deformation caused by vibration or shaking in the pipeline.

[0043] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0044] The above-described embodiments only represent several implementation manners of the present application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the patent protection scope of the present application shall be subject to the appended claims.
