Description

Technical Field

[0001] This utility model relates to a valve hanger, belonging to the technical field of valve auxiliary facilities. Background Technology

[0002] A valve is a device used to control the flow of fluids (such as liquids, gases, and steam), and is widely used in industries such as construction, water supply, gas supply, heating, and petrochemicals. Based on different applications and working principles, valves can be classified into various types, such as gate valves for fully opening or closing fluid flow; ball valves for opening, closing, and regulating flow; butterfly valves that control fluid flow via a rotating disc, mainly used for flow control in large-diameter pipelines; and gate valves that control fluid flow via a rising gate, mainly used for fully opening or closing fluid flow. Valve hangers are required in the production and market for valves.

[0003] For example, Chinese utility model patent CN221257808U discloses "a valve hanger," which includes a hanging rod with a hook fixedly connected to the top. Support rods A are hinged to both sides of the bottom of the hanging rod, and a rotating column is fixedly connected to the other end of each support rod A. A horizontal head is rotatably connected to the surface of the rotating column, and a support plate is fixedly connected to the other end of the horizontal head. This utility model's hanger has the characteristic of being multi-adaptable.

[0004] The aforementioned patent uses the method of adjusting the distance between the support plates to hold the valve in place. However, the inner wall of the valve pipe is smooth, and the valve may fall due to its own weight during the hanging process. Therefore, this utility model proposes a valve hanger to solve the above problem. Utility Model Content

[0005] Based on the above background, the purpose of this utility model is to provide a valve hanger to solve the problems in the background art.

[0006] This utility model provides the following technical solution:

[0007] A valve hanger includes a circular top plate. A set of symmetrical connecting plates is provided at the bottom of the circular top plate. A hinge interface is provided at the bottom of the connecting plates. A telescopic hole is provided in the center of the circular top plate. A movable rod passes through the telescopic hole. A mounting plate is provided at the bottom of the movable rod. A positioning block is provided at the bottom of the mounting plate. A movable groove is provided in the center of the positioning block. Through grooves are provided on the front and rear inner walls of the movable groove. Corresponding through grooves, a set of rotating rods is movably arranged within each through groove. A connecting rod is welded to each of the rotating rods. The middle portion of the connecting rod on each rotating rod is hinged to the lower end of the hinge interface on the connecting plate.

[0008] Preferably, the movable rod is located on the upper part of the circular top plate and is provided with a limiting plate, and the top of the limiting plate is provided with a hook.

[0009] Preferably, a spring is fitted onto the movable rod, and the spring is located between the mounting plate and the circular top plate.

[0010] Preferably, the connecting rod has an extension rod on the inner side of the end away from the connection with the rotating rod.

[0011] Preferably, the inner side of the extension rod is provided with an arc-shaped limiting strip.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] This utility model discloses a valve hanger. In use, the hook moves upward, causing the movable rod to move upward within the telescopic hole. Simultaneously, this moves the mounting plate and the positioning block at the bottom of the mounting plate upward. As the positioning block moves upward, a set of rotating rods slightly rotate within the through groove and move away from each other. At this time, the end of the connecting rod away from the rotating rod moves closer together under the hinge action of the connecting rod and the hinge interface. Ultimately, this causes the limiting strips to move closer together and lock onto the inner side of the flange on the valve pipeline. Valves with valve pipeline specifications within the maximum distance between the limiting strips can be suspended. Furthermore, the limiting strips locking onto the inner side of the flange on the valve pipeline prevent the valve from falling during suspension. Attached Figure Description

[0017] The technical solution of this utility model will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings. It should be understood that the implementation of this utility model is not limited to the following embodiments, and any modifications and / or alterations made to this utility model will fall within the protection scope of this utility model.

[0018] In this invention, unless otherwise specified, all parts and percentages are by weight, and the equipment and raw materials used are commercially available or commonly used in the field. Unless otherwise specified, the methods in the following embodiments are conventional methods in the field. Unless otherwise specified, the components or equipment in the following embodiments are general standard parts or components known to those skilled in the art, and their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0019] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. In the following detailed description, many specific details are set forth to facilitate explanation and provide a comprehensive understanding of the embodiments of the present invention. However, one or more embodiments may be practiced by those skilled in the art without these specific details.

[0020] like Figure 1 As shown, a valve hanger includes a circular top plate 1. A set of symmetrical connecting plates 2 are provided at the bottom of the circular top plate. A hinge interface 3 is provided at the bottom of the connecting plates 2. A telescopic hole is provided in the center of the circular top plate 1. A movable rod 4 passes through the telescopic hole. A mounting plate 5 is provided at the bottom of the movable rod 4. A positioning block 6 is provided at the bottom of the mounting plate 5. A movable groove 7 is provided in the center of the positioning block 6. Through grooves are provided on both the front and rear inner walls of the movable groove 7. A set of rotating rods 8 are movably arranged within the through grooves. A connecting rod 9 is welded to each of the rotating rods 8. The middle part of the connecting rod 9 on each of the rotating rods 8 is hinged to the lower end of the hinge interface 3 on the connecting plates 2. A limiting plate 10 is provided on the upper part of the circular top plate 1, and a hook 11 is provided on the top of the limiting plate 10.

[0021] In the above technical solution, during use, the hook 11 moves upward, causing the movable rod 4 to move upward within the telescopic hole. Simultaneously, this causes the mounting plate 5 and the positioning block 6 at the bottom of the mounting plate 5 to move upward. As the positioning block 6 moves upward, a set of rotating rods 8 rotate slightly within the through groove and move away from each other. At this time, the end of the connecting rod 9 away from the rotating rod 8 moves closer together under the hinge action of the connecting rod 9 and the hinge interface 3. Ultimately, this causes the limiting strips 14 to move closer together and lock onto the inner side of the flange on the valve pipeline. Valves with valve pipeline specifications within the maximum distance between the limiting strips 14 can be suspended. Furthermore, by setting the limiting strips 14 to lock onto the inner side of the flange on the valve pipeline, the valve can be prevented from falling during suspension.

[0022] In this utility model, a spring 12 is sleeved on the movable rod 4. The spring 12 is located between the mounting plate 5 and the circular top plate 1. The weight of the circular top plate 1 and the connecting plate 2 is greater than the elastic force of the spring 12.

[0023] In the above technical solution, by setting spring 12, the elastic restoring force of spring 12 can ensure that the distance between the limit strips 14 is always at its maximum value when the valve is not being hung, which makes it convenient for the valve to be hung.

[0024] In this invention, an extension rod 13 is provided on the inner side of the end of the connecting rod 9 away from the connection point with the rotating rod 8. An arc-shaped limiting strip 14 is provided on the inner side of the extension rod 13.

[0025] In this utility model, by setting an extension rod 13 and setting a limiting strip 14 on the inner side of the extension rod 13, the valve can be supported when it is suspended, and the valve can be prevented from falling out of this utility model.

[0026] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
