Description

Technical Field

[0001] The invention relates to the technical field of pressure gauge spring tube production and processing equipment, in particular to a high-strength corrosion-resistant spring tube. Background Art

[0002] The spring tube of a pressure gauge usually refers to a hollow tube designed in a single-ring "C" shape or a similar shape, with a non-circular cross-section (such as an elliptical shape). It is the main sensitive element of a spring tube pressure gauge. When this tube is subjected to fluid pressure, it will deform, thereby converting the measured pressure into a measurable displacement.

[0003] The elasticity of traditional pressure gauge spring tubes is often fixed during production, and their scope of application is relatively limited, and they are only suitable for specific working environments. Summary of the invention

[0004] 1. Technical issues to be resolved In view of the deficiencies in the prior art, the present invention provides a high-strength corrosion-resistant spring tube, which solves the problem that the elasticity of the traditional pressure gauge spring tube is often fixed during production, and its application scope is relatively limited and is only suitable for specific working environments.

[0005] (II) Technical solution To achieve the above objectives, the present invention is implemented through the following technical solutions: a high-strength, corrosion-resistant spring tube, comprising a spring tube body, the spring tube body being in a crescent shape, a spring tube inner cavity being provided inside the spring tube body, two groups of auxiliary rebound mechanisms being arranged inside the spring tube inner cavity, the two groups of auxiliary rebound mechanisms being respectively fixedly connected to the two inner side walls of the spring tube inner cavity, the two groups of auxiliary rebound mechanisms each comprising a plurality of rebound auxiliary units, and the rebound auxiliary units in the two groups of auxiliary rebound mechanisms being intermittently distributed.

[0006] Preferably, the auxiliary rebound unit includes an adjusting shaft, which is fixedly connected to the inner wall of the spring tube body, and one end of the adjusting shaft away from the inner wall of the spring tube body is fixedly connected to a mounting plate, and both sides of the mounting plate are fixedly connected to elastic auxiliary parts, and one end of the elastic auxiliary part away from the mounting plate is fixedly connected to the same inner wall of the spring tube body as the auxiliary rebound unit.

[0007] Preferably, the adjusting shaft is an electric telescopic shaft.

[0008] Preferably, the elastic auxiliary member is a spring.

[0009] Preferably, the outer surface of the spring tube body is plated with an anti-corrosion tin layer.

[0010] Working principle: When in use, the elastic strength of the spring tube can be changed according to needs to adapt to different working environments. When different elastic coefficients need to be adjusted to adapt to different working environments, the elastic force of the elastic auxiliary parts can be changed by changing the extension length of the adjustment shafts of multiple auxiliary rebound units, thereby changing the elastic force of the entire spring tube to adapt to different work needs. After a certain period of use, when it is necessary to detect the elastic state of the spring tube, the adjustment shaft is placed in the initial state to check whether its elastic force is suitable for the current working state. When the elastic state of the spring tube does not meet the working state, the auxiliary rebound unit can also be used to compensate for the elastic force to achieve an adaptable state, thereby increasing the service life of the spring tube.

[0011] (III) Beneficial effects The present invention provides a high-strength corrosion-resistant spring tube. It has the following beneficial effects: 1. When the high-strength corrosion-resistant spring tube needs to adjust different elastic coefficients to adapt to different working environments, the elastic force of the elastic auxiliary parts can be changed by changing the elongation length of the adjustment shafts of multiple auxiliary rebound units, thereby changing the elastic force of the entire spring tube to adapt to different working requirements.

[0012] 2. After the high-strength and corrosion-resistant spring tube has been used for a certain period of time, when it is necessary to detect the elastic force state of the spring tube, the adjustment shaft is placed in the initial state to check whether its elastic force is suitable for the current working state. When the elastic force state of the spring tube does not meet the working state, the auxiliary rebound unit can also be used to compensate for the elastic force to achieve an adaptable state, thereby increasing the service life of the spring tube.
