Description

Technical Field

[0001] This application relates to the field of gas storage equipment, and in particular to a special wrench for disassembling and assembling the vacuum gauge of a high vacuum valve. Background Technology

[0002] Gas storage tanks are commonly used in industrial production to provide compressed gases. To maximize storage capacity, the gas is typically stored in a liquid state within the tank. During use, it is converted into gas by a vaporizer and supplied to downstream systems. To ensure the safety of the storage tank, its vacuum level frequently needs to be measured. This is done by connecting an external thermocouple vacuum gauge to the high-vacuum valve on the tank. However, when the vacuum gauge tube on the high-vacuum valve fails, the thermocouple vacuum gauge cannot perform a normal measurement. The conventional approach is to evacuate the medium from the tank and disrupt its vacuum environment, then replace the high-vacuum valve. After replacing the valve, the tank's interlayer must be evacuated and the internal medium replenished.

[0003] Because it is difficult to empty the gas storage tank during normal operation, and emptying it would waste resources, and the vacuum gauge tube on the high vacuum valve is a special type of union, ordinary wrenches cannot be used for online installation and removal. Therefore, it is necessary to develop a special wrench that can be used for online installation and removal of the vacuum gauge tube on high vacuum valves. Utility Model Content

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods.

This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0025] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0026] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0027] The following is in conjunction with the appendix Figures 1 to 3 The provided embodiments further illustrate the special wrench for disassembling and assembling the vacuum gauge tube of the high vacuum valve proposed in this application.

[0028] It should be noted that the vacuum gauge tube involved in this application is a sensor device installed on the gas storage tank through a high vacuum valve for measuring the vacuum degree of the gas storage tank. Common vacuum gauge tubes are mainly cylindrical with an outer diameter of 38mm-39mm. The side of the vacuum gauge tube is provided with six evenly distributed grooves with a groove depth of approximately 1mm.

[0029] like Figure 1 As shown, the first embodiment of this application provides a special wrench 100 for disassembling and assembling a vacuum gauge tube of a high vacuum valve, including a collar portion 110 and a handle portion 120, one end of which is connected to the collar portion 110. The collar portion 110 is annular, and a circular inner ring 111 is provided inside the collar portion 110. The collar portion 110 is fitted onto the vacuum gauge tube to be disassembled or assembled through the inner ring 111. Further, the diameter of the inner ring 111 is greater than or equal to the outer diameter of the vacuum gauge tube to be disassembled or assembled. In some embodiments, the diameter d of the inner ring 111 is 39mm to better fit the specifications of the vacuum gauge tube, so that the collar portion 110 can fit tightly against the vacuum gauge tube when it is fitted onto the outside of the vacuum gauge tube. The inner ring 111 has three protrusions 112, which are evenly distributed on the inner wall of the inner ring 111. The positions of the protrusions 112 match the positions of the grooves on the vacuum gauge tube to be disassembled. When the collar portion 110 is fitted onto the vacuum gauge tube to be disassembled, the protrusions 112 are embedded in the grooves on the vacuum gauge tube. In some embodiments, the length a of the protrusions 112 extending towards the center of the inner ring 111 is 1 mm, so as to better embed into the groove of the vacuum gauge tube and fit tightly with the groove; furthermore, the width of the protrusions 112 is in the range of 2.3 mm-2.6 mm, preferably 2.5 mm, so that the protrusions 112 can fit tightly with the groove.

[0030] Furthermore, such as Figure 1 As shown, the outer diameter D of the collar portion 110 is 46mm to 53mm, ensuring that the collar portion 110 has sufficient strength.

[0031] Furthermore, such as Figure 1 As shown, the length of the handle part 120 is 150mm to 300mm. When the operator holds the handle part 120, he can quickly operate the special wrench 100 for vacuum gauge tube disassembly and assembly, thereby realizing the quick disassembly and assembly of the vacuum gauge tube on the high vacuum valve.

[0032] In some embodiments, to adapt to more work scenarios, the handle 120 can be configured as a telescopic handle, and the length of the handle 120 can be adjusted according to the needs of the actual scenario to achieve the best use effect.

[0033] In some embodiments, the handle portion 120 can also be detachably connected to the collar portion 110. The handle portion 120 can be detached and replaced or a collar portion 110 of different specifications can be replaced to adapt to more working scenarios. When not in use, the collar portion 110 and the handle portion 120 can be separated and stored, which can effectively reduce the requirements for storage space.

[0034] In some embodiments, the handle portion 120 may also be covered with an anti-slip sleeve to prevent slippage during operation and further improve safety.

[0035] like Figure 2 As shown, the second embodiment of this application provides another special wrench 100' for disassembling and assembling vacuum gauge tubes of high vacuum valves. The structure of the special wrench 100' for disassembling and assembling vacuum gauge tubes in this embodiment is basically the same as that of the special wrench 100 for disassembling and assembling vacuum gauge tubes provided in the first embodiment. The difference between the two is that the inner ring 111 of the collar portion 110 in this embodiment is provided with six protrusions 112. The six protrusions 112 are evenly distributed on the inner wall of the inner ring 111 and can cooperate with the six grooves on the outside of the vacuum gauge tube.

[0036] like Figure 3 As shown, the third embodiment of this application provides another type of vacuum gauge tube disassembly and assembly wrench 100 for high vacuum valves. The structure of the vacuum gauge tube disassembly and assembly wrench 100 in this embodiment is basically the same as that of the vacuum gauge tube disassembly and assembly wrench 100 provided in the first embodiment. The difference between the two is that the inner ring 111 of the collar portion 110 in this embodiment is provided with only two bosses 112. The two bosses 112 are symmetrically distributed on the inner wall of the inner ring 111, which can achieve the same effect.

[0037] It should be understood that in other embodiments of this application, the number of protrusions 112 can also be set to four or five. As long as the number of protrusions 112 is two to six, the same effect can be achieved, satisfying the structural requirements of this application and falling within the protection scope of this application.

[0038] The process of disassembling and assembling the vacuum gauge tube using the special wrench for vacuum gauge tube disassembly and assembly of this application is as follows: First, remove the dust cover of the vacuum gauge tube on the high vacuum valve and clean the impurities in the groove of the vacuum gauge tube; then, adjust the angle of the collar part 110 of the special wrench 100 for vacuum gauge tube disassembly and assembly so that the boss 112 is aligned with the groove of the vacuum gauge tube, and then put the collar part 110 on the outside of the vacuum gauge tube, with the boss 112 embedded in the groove of the vacuum gauge tube, and the collar part 110 and the boss 112 tightly fitting with the vacuum gauge tube; operate the handle part 120 to loosen the vacuum gauge tube. During this process, it is necessary to fix the high vacuum valve to avoid damaging the vacuum of the gas storage tank when disassembling the vacuum gauge tube; after loosening the vacuum gauge tube, remove the vacuum gauge tube, and finally, as soon as possible, install the new spare part onto the high vacuum valve using the special wrench 100 for vacuum gauge tube disassembly and assembly to complete the replacement process.

[0039] The vacuum gauge tube disassembly and assembly wrench 100 of this application for high vacuum valves can tightly fit the vacuum gauge tube on the high vacuum valve, making operation convenient and efficient. It enables rapid online disassembly and assembly of the vacuum gauge tube without the need to empty the gas storage tank for maintenance, reducing operation and maintenance costs. It also ensures the vacuum level of the gas storage tank during disassembly and assembly, making it convenient and safe. The vacuum gauge tube disassembly and assembly wrench 100 of this application effectively solves the problem of the inability to measure the vacuum level of the gas storage tank due to abnormal vacuum gauge tube, ensuring smooth production.

[0040] It is understood that the above embodiments only illustrate preferred embodiments of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this application. It should be noted that, for those skilled in the art, without departing from the concept of this application, the above technical features can be freely combined, and several modifications and improvements can be made, all of which fall within the protection scope of this application. Therefore, all equivalent transformations and modifications made within the scope of the claims of this application should fall within the coverage of the claims of this application.
