Description

Technical Field

[0001] The present application relates to the field of valve regulation technology, and in particular to a valve regulation device. Background Art

[0002] With the rapid development of industrial technology, various types of industrial equipment are becoming more and more popular, and various types of valves are being used more and more widely in industrial equipment to simplify the design structure of industrial equipment. When the valve is manufactured, especially the expansion valve, the position of the valve adjustment rod will be relatively fixed. For some machines equipped with expansion valves, during the experimental verification process, there is a situation where the position of the adjustment rod needs to be adjusted so that the machine meets the experimental requirements, such as high and low temperature refrigeration, high and low temperature heating, soaking and cold start experiments, frequent start and stop, etc.

[0003] However, due to the different installation or use environments of various types of equipment, the expansion valve installation position of some equipment in special environments is in a relatively narrow environment, which makes it difficult to adjust the adjustment rod. And when the equipment is installed on the enthalpy difference table and the adjustment rod of the expansion valve needs to be adjusted, the panel needs to be opened, which will cause the air on the evaporator side or condenser side of the equipment to be blown out directly by the fan without passing through the heat exchanger, making the equipment prone to alarm failure.

[0004] Therefore, it is necessary to provide an improved valve regulating device to solve some or all of the above problems. Utility Model Content

DETAILED DESCRIPTION

[0029] like Figures 1 to 4 As shown, the valve regulating device of the present application is connected to the valve member 1, so that people can more conveniently and accurately regulate the valve member 1. Specifically, the valve regulating device includes a regulating mechanism 2 and a box body 3. The regulating mechanism 2 is arranged in the box body 3, and the regulating mechanism 2 is connected to the valve member 1, so that the valve member 1 is fixed to the box body 3 and the valve member 1 is regulated.

[0030] In one embodiment, part of the valve component 1 extends into the housing 3 to facilitate the connection between the regulating mechanism 2 and the valve component 1. The valve component 1 includes a valve body 11, a valve regulating rod 12, a first through pipe 13 and a second through pipe 14. The valve regulating rod 12 is rotatably disposed in the valve body 11, and part of the valve regulating rod 12 protrudes out of the valve body 11. The valve regulating rod 12 is used to adjust the flow rate of the medium flowing through the valve component 1. The first through pipe 13 and the second through pipe 14 are disposed on the valve body 11, and the first through pipe 13 and the second through pipe 14 are used for the medium to flow into and out of the valve component 1. Specifically, the first through pipe 13 and the second through pipe 14 are disposed back to back on the valve body 11. In this article, the valve component 1 is described as an expansion valve.

[0031] Further integration Figure 5 and Figure 6 As shown, in one embodiment, the adjustment mechanism 2 includes a drive assembly 21, a scale member 22, a scale indicator 23, a middle connection assembly 24 and a valve fixing assembly 25. The drive assembly 21 is disposed in the housing 3 and is used to drive the scale indicator 23 and part of the valve member 1 to rotate. Specifically, the drive assembly 21 is connected to the valve adjustment rod 12 through the middle connection assembly 24, and drives the valve adjustment rod 12 to rotate relative to the valve body 11. In this way, the valve adjustment device can adjust the valve member 1 more conveniently, accurately and quickly.

[0032] The driving assembly 21 includes a driving member 211 and a support frame 212. The driving member 211 is fixed on the support frame 212, and the support frame 212 is fixed in the box body 3. The driving member 211 is preferably a motor, so as to accurately and quickly drive the valve adjustment rod 12 to rotate, and no manual adjustment is required, which is convenient for remote control and improves work efficiency.

[0033] The support frame 212 includes a base 2121 and a mounting plate 2122. The mounting plate 2122 is protruded from the base 2121, the driving member 211 is fixed on the mounting plate 2122, and the base 2121 is fixed on the bottom plate of the box body 3. In order to make the driving member 211 conveniently docked with the valve regulating rod 12, the base 2121 can be adjusted in height relative to the bottom plate of the box body 3. In another embodiment, the mounting plate 2122 can be relatively movably arranged on the base 2121, so as to facilitate the adjustment of the position of the driving member 211 and facilitate the efficient docking of the driving member 211 with the valve regulating rod 12.

[0034] In one embodiment, the scale member 22 and the scale indicator 23 are located in the box 3, and the scale member 22 and the scale indicator 23 are protected by the box 3 to prevent dust and other impurities from adhering. The scale member 22 is fixed to the valve member 1. The scale indicator 23 is provided on the valve member 1 and can rotate relative to the scale member 22. In this way, when the valve adjustment device adjusts the valve member 1, the angle adjustment is more accurate and the angle value display is more obvious.

[0035] Specifically, the scale member 22 is fixed to the valve body 11, and the scale indicator 23 is relatively fixedly arranged on the valve adjusting rod 12. The scale indicator 23 is used to indicate the scale mark on the scale member 22, so as to facilitate the user to clearly understand the rotation angle of the adjusting rod 12 relative to the valve body 11. In the direction from the valve member 1 to the drive assembly 21, the scale indicator 23 is located between the drive assembly 21 and the scale member 22, so that the scale indicator 23 can more clearly indicate the scale mark on the scale member 22.

[0036] The scale markings on the scale member 22 can be Arabic numerals, Roman scales, bar scales, dot scales or scales of other shapes that can represent marks. The scale markings on the scale member 22 can be a single scale setting or a combination of multiple scales, which will not be repeated in this article.

[0037] The scale member 22 and the scale indicator 23 are both disc-shaped structures. Preferably, the scale member 22 is provided with scale values, and at least the scale member 22 is provided with scale values, and the scale indicator 23 is provided with an indication mark. When the valve member 1 is in the valve closed state, the indication mark on the scale indicator 23 preferably coincides with the zero scale value on the scale member 22.

[0038] In one embodiment, the indication mark on the scale indicator 23 may be Arabic numerals, Roman scales, bar scales, dot scales, or scales of other shapes that can represent marks. Preferably, the scale member 22 and the scale indicator 23 are both disc-shaped structures with scale values. And when the valve member 1 is in the valve closed state, the scale value on the scale indicator 23 coincides with the scale value on the scale member 22. Further, when the valve member 1 is in the valve closed state, at least the zero scale value on the scale indicator 23 coincides with the zero scale value on the scale member 22.

[0039] In this way, by comparing the scale values ​​on the scale member 22 with the scale values ​​on the scale indicator 23, the rotation angle of the valve adjusting rod 12 relative to the valve body 11 can be accurately displayed. At the same time, scale values ​​are provided on both the scale member 22 and the scale indicator 23, so that the rotation angle of the valve adjusting rod 12 can be determined by observing the scale values ​​on the scale member 22, and the rotation angle of the valve adjusting rod 12 can also be determined by observing the scale values ​​on the scale indicator 23.

[0040] In another embodiment, the scale indicator 23 may also be a pointer structure, and when the valve member 1 is in the valve closed state, the scale indicator 23 indicates the zero scale value on the scale member 22. Of course, the scale member 22 may also be fixed to the housing 3, and the scale member 22 and the valve member 1 are located on the same side plate of the housing 3; or the scale member 22 is fixed to the driving member 211, the support frame 212 or the valve fixing assembly 25 relative to the valve regulating rod 12; the scale indicator 23 may be fixed to the intermediate assembly 24 or the rotating shaft of the driving member 211.

[0041] Further integration Figure 7 and Figure 8 As shown, in one embodiment, the middle connection assembly 24 is disposed in the housing 3, and one end of the middle connection assembly 24 is connected to the valve member 1, and the other end is connected to the driving assembly 21. Specifically, one end of the middle connection assembly 24 is fixed to the valve regulating rod 12, and the other end is fixed to the driving member 211. The middle connection assembly 24 includes a universal coupling 241, a connecting column 242, and a coupling 243.

[0042] The universal coupling 241 is connected between the valve member 1 and the drive assembly 21. Specifically, the connecting column 242 is connected between the universal coupling 241 and the coupling 243, the other end of the coupling 243 is connected to the drive assembly 21, one end of the universal coupling 241 is connected to the valve adjustment rod 12, and the other end is connected to the connecting column 242. That is, in the direction from the valve member 1 to the drive member 211, the universal coupling 241, the connecting column 242 and the coupling 243 are arranged in sequence.

[0043] The two ends of the universal coupling 241 can be relatively swingable. Specifically, the universal coupling 241 includes a first connection end 2411 and a second connection end 2412. The first connection end 2411 is connected to the valve regulating rod 12, and the second connection end 2412 is connected to the connection column 242. The first connection end 2411 and the second connection end 2412 can relatively swing.

[0044] Such an arrangement ensures that when the rotating axes of the valve adjusting rod 12 and the driving member 211 are not in the same direction and there is an angle deviation, the driving member 211 can still be connected to the valve adjusting rod 12 through the universal coupling 241, and drive the valve adjusting rod 12 to rotate, thereby improving the convenience of assembling the valve adjusting device and the valve member 1.

[0045] While ensuring that the valve adjusting rod 12 and the rotating shaft of the driving member 211 can be smoothly connected, the universal coupling 241 can be a G-type precision cross universal joint coupling (single section) or a GD-type precision cross universal joint coupling (double section), etc., which is not limited in this article.

[0046] Further integration Fig. 9As shown, in one embodiment, the valve fixing assembly 25 is provided in the box body 3, and the valve fixing assembly 25 is used to fix and support the valve member 1. Specifically, the valve fixing assembly 25 includes an inner fixing member 251 and an outer fixing member 252. The inner fixing member 251 and the outer fixing member 252 are arranged opposite to each other on one side of the box body 3. Further, the inner fixing member 251 is provided in the box body 3, and is at least used to support the valve member 1. The outer fixing member 252 is located outside the box body 3, and is at least used to lock the valve member 1 to the box body 3.

[0047] The inner fixing member 251 includes a support plate 2511 and a first clamp 2512. The support plate 2511 is fixed to the bottom plate of the box body 3, and the first clamp 2512 is arranged on the support plate 2511. A portion of the valve body 11 extends into the box body 3, and the first clamp 2512 and the support plate 2511 are fixedly sleeved on the valve body 11 together, thereby supporting and fixing the valve member 1.

[0048] The external fixing member 252 includes a second clamp 2521 and a third clamp 2522. The second clamp 2521 is sleeved on the first through pipe 13, and the end of the second clamp 2521 is fixed to the box body 3. The third clamp 2522 is sleeved on the second through pipe 14, and the end of the third clamp 2522 is fixed to the box body 3. The second clamp 2521 and the third clamp 2522 jointly lock the valve member 1 in the direction toward the box body 3.

[0049] The box body 3 includes a box body 31 and a box cover 32. The valve member 1 is fixed to the box body 31, and the drive assembly 21, the scale member 22, the scale indicator 23, the intermediate assembly 24 and the inner fixing member 251 are located in the box body 31. The box cover 32 is detachably covered on the box body 31 to prevent dust and other impurities from entering the box body 3.

[0050] In the present application, the driving member 211 is preferably a motor. When the driving member 211 drives the valve adjusting rod 12 to rotate, in order to facilitate determining the rotation angle of the valve adjusting rod 12, the valve adjusting rod 12 rotates half a circle for every 200 steps executed by the driving member 211; the valve adjusting rod 12 rotates one circle for every 400 steps executed by the driving member 211.

[0051] The valve regulating device of the present application is provided with a driving assembly 21, so that the valve regulating device can adjust the valve member 1 more conveniently, accurately and quickly. At the same time, the scale member 22 is fixed to the valve member 1, and the scale indicator 23 can rotate relative to the scale member 22, so that when the valve regulating device adjusts the valve member 1, the angle adjustment is more accurate and the angle display is more obvious, thereby facilitating people to control the adjustment angle and improving work efficiency.
