[0002] Pressure systems and pressure equipment usually display the operating pressure through pressure gauges. A pressure gauge is an instrument that uses an elastic element as a sensitive element to measure and indicate the pressure higher than the ambient pressure, and is widely used in fields such as thermal pipelines, oil and gas transmission, and water and gas supply systems. In addition to selecting the pressure gauge according to the allowable pressure range, during actual operation, it is also necessary to set the yellow zone, green zone, and red zone indications according to the working conditions to indicate the warning, normal, and alarm intervals, and prompt the inspection personnel to judge the operating conditions of the device and process.
[0003] Generally, the interval indications painted on the dial of the pressure gauge itself cannot adapt to various devices and processes under different working conditions, and it is necessary to set additional interval indications according to the actual working conditions.

[0024] Next, the technical solution of the present utility model will be clearly and completely described in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative work shall fall within the protection scope of the present utility model.

[0026] In the description of the present utility model, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.
[0027] In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.
[0028] Such as Figure 1 、 Figure 2 、 Figure 4 As shown, it is a specific embodiment of the pressure gauge interval indicating device of the present utility model. The indicating device is installed on the pressure gauge to realize the indication of different pressure intervals, so as to facilitate the inspection personnel to judge the operating conditions of the device and the process.
[0029] Such as Figure 2 、 Figure 4As shown, the pressure gauge interval indicating device 100 includes at least two sleeves 10, and the sleeves 10 are adapted to be sleeved on the circumferential surface of the pressure gauge body 200. Among them, among the multiple sleeves 10, they can be directly sleeved on different circumferential surface areas of the pressure gauge body 200 respectively, or multiple sleeves 10 can be stacked and sleeved on the circumferential surface of the pressure gauge body 200. An indicating edge 20 covering a partial area of the dial of the pressure gauge body 200 is provided on each sleeve 10, and the colors of the indicating edges 20 of each sleeve 10 are different, and multiple different indicating intervals are formed by the indicating edges 20 of different colors.
[0030] When using the above-mentioned indicating device for pressure indication, the sleeve 10 can be sleeved on the pressure gauge body 200, and the sleeve 10 is rotated to make the indicating edge 20 rotate to the preset pressure interval to be indicated, so as to realize the indication function of multiple pressure intervals. For example, when two sleeves 10 are used to indicate three pressure intervals, the two sleeves 10 can be sleeved on the pressure gauge body 200, the indicating edge 20 of one sleeve 10 covers the low-pressure interval, and the indicating edge 20 of the other sleeve 10 covers the high-pressure interval, and the part between the two indicating edges 20 is the medium-pressure interval.
[0031] Specifically, in an optional implementation manner, the sleeve 10 is a thin-walled structure made of an elastic material, and the sleeve 10 and the indicating edge 20 are integrally bent and formed. The indicating edge 20 is located at one end region along the axial direction of the sleeve 10, which can make the indicating edge 20 located outside the sleeve 10 and not blocked by the sleeve 10, facilitating the user to observe the indicating edge 20 from different sides.
[0032] Specifically, in an optional implementation manner, the indicating edge 20 is formed into a fan-shaped fin structure, and its width along the radial direction is small to avoid blocking the position of the pressure pointer of the pressure gauge itself. When manufacturing, the circumferential range of the indicating edge 20 of the sleeve 10 can be made larger, and the indicating edges 20 of adjacent sleeves 10 are partially overlapped when in use. In this way, the indicating device can be adapted to the pressure ranges under different working conditions. At the same time, since the indicating edge 20 is a thin-walled fin structure made of an elastic material, when the range of the indicating edge 20 is too large, it can be adapted to the pressure indication range by cutting.
[0033] Specifically, in an optional implementation manner, as Figure 1 、 Figure 2 shown, the sleeve 10 is an annular sleeve 10, which includes a first sleeve 10a and a second sleeve 10b. The first sleeve 10a is adapted to be rotatably sleeved on the circumferential surface of the pressure gauge body 200, and the second sleeve 10b can be rotatably sleeved on the first sleeve 10a. By respectively rotating the circumferential positions of the first sleeve 10a and the second sleeve 10b, the indicating edges 20 located on both of them can be rotated to the pressure indication interval set according to the working conditions.
[0034] Under some working conditions, it is necessary to display three pressure ranges through three different color markings. Therefore, in an alternative embodiment, as Figure 2 shown, the sleeve body 10 further includes a third sleeve body 10c, and the third sleeve body 10c is rotatably sleeved on the second sleeve body 10b. In this way, by rotating the three sleeve bodies 10, the indicators 20 on the three sleeve bodies 10 can be respectively rotated into the set pressure indication ranges.
[0035] Specifically, the coverage area of the indicator 20 of the second sleeve body 10b is larger than the coverage area of the indicator 20 of the first sleeve body 10a or the third sleeve body 10c. For example, as Figure 2 shown, the central angle of the indicator 20 of the first sleeve body 10a is between 60° and 100°, the central angle of the indicator 20 of the second sleeve body 10b is between 150° and 180°, and the central angle of the indicator 20 of the third sleeve body 10c is between 60° and 100°. This can facilitate the indicator 20 of the second sleeve body 10b to cover part of the indicator 20 of the first sleeve body 10a, and the indicator 20 of the third sleeve body 10c to cover part of the indicator 20 of the second sleeve body 10b.
[0036] Specifically, in an alternative embodiment, as Figure 2 shown, the indicator 20 of the first sleeve body 10a is green, the color of the indicator 20 of the second sleeve body 10b is yellow, and the color of the indicator 20 of the third sleeve body 10c is red. According to industry habits, green usually represents the safe or normal range, red represents the range exceeding the safety range or the alarm range, and yellow represents the warning range or the intermediate range that needs attention. Displaying the three sleeve bodies 10 with the above three different colors can better play an indicating role.
[0037] Specifically, in another specific embodiment, as Figure 4 shown, the sleeve body 10 is an annular sleeve body with a notch, that is, the sleeve body 10 is sleeved on a partial circumferential surface of the pressure gauge body 200, as Figure 4 、 Figure 5As shown, the sleeve body 10 includes a first sleeve body 10a and a second sleeve body 10b. The first sleeve body 10a is adapted to be rotatably sleeved on a partial circumference of the pressure gauge body 200, and the second sleeve body 10b is adapted to be rotatably sleeved on a partial circumference of the pressure gauge body 200. The areas of the pressure gauge body 200 covered by the first sleeve body 10a and the second sleeve body 10b can be overlapped or separated. Among them, the indicating edge 20 of the first sleeve body 10a is green and is used to indicate the low-pressure range of the safe pressure, and the indicating edge 20 of the second sleeve body 10b is red and is used to indicate the high-pressure range exceeding the safe range. In this way, the area between the indicating edge 20 of the first sleeve body 10a and the indicating edge 20 of the second sleeve body 10b is the medium-pressure range for indicating a warning effect.
[0038] As Figure 3 , Figure 5 shown is a specific implementation manner of the pressure gauge provided by the present utility model. The pressure gauge includes a pressure gauge body 200 and a pressure gauge range indicating device 100. Figure 3 Shown is a pressure gauge with a pressure gauge range indicating device 100 of the first structural form sleeved on the pressure gauge body 200. Figure 5 Shown is a pressure gauge with a pressure gauge range indicating device 100 of the second structural form sleeved on the pressure gauge body 200. By sleeving the above pressure gauge range indicating device 100 on the pressure gauge body 200, the pressure range that needs to be warned can be clearly indicated.
[0039] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present utility model.
