Description

Technical Field

[0001] The utility model relates to the technical field of thermocouple temperature detection sensors, in particular to a detection instrument for the information industry. Background Art

[0002] Some industrial production processes are carried out continuously. Once interrupted, it will lead to a serious decline in product quality, damage to production equipment, and even safety accidents. For example, in some continuous reaction processes in the chemical industry, the reaction temperature needs to be strictly controlled, and thermocouple sensors are key equipment for monitoring temperature. In the production of some high-value products, stopping production may cause the workpieces being processed to be scrapped, resulting in huge losses. As we all know, the above-mentioned production equipment is generally equipped with a variety of detection equipment such as temperature detection instruments, pressure detection instruments, flow detection instruments and level detection instruments, and the above-mentioned detection equipment will inevitably fail due to various factors. For example, thermocouple detection temperature sensors are usually used for a long time in harsh environments such as high temperature, corrosion, and vibration. They are prone to problems such as aging, breakage, and insulation damage of thermocouple wires, resulting in inaccurate measurements or failures. For example, in high-temperature production processes such as metallurgy and chemical industry, thermocouples are often affected by the dual effects of high temperature and chemical corrosion, and their service life will be subject to certain restrictions.

[0003] However, thermocouple temperature sensors are generally connected to equipment through flanges or threaded caps, and the connection structure is relatively simple. When the thermocouple temperature sensor is damaged, the connecting pipe of the thermocouple temperature sensor is pulled out, and the connecting hole in the connecting equipment will be exposed, connecting the outside air and the inside of the connecting equipment. The exposed connecting hole will leak the pressure and heat inside the connecting equipment, scalding the maintenance personnel. Therefore, thermocouple temperature sensors cannot be replaced online. In view of this, this article proposes a detection instrument for the information industry. Utility Model Content

[0004] The purpose of the utility model is to solve the problem in the prior art that the thermocouple detection temperature sensor cannot be replaced online, and to propose a detection instrument for the information industry.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A detection instrument for the information industry, comprising an instrument wiring housing and a connecting pipe, wherein a flange is detachably fixedly mounted on the end of the connecting pipe;

[0007] A hole self-sealing component is coaxially arranged below the connecting hole in the flange.

[0008] Preferably, the hole self-sealing assembly includes a guide cylinder and three sliders, the top end of the guide cylinder is fixedly installed under the flange, the three sliders are interlocked with each other, and the three sliders are respectively slidably installed in the three slide grooves in the guide cylinder, the above three slide grooves are connected to each other, and the back sides of the three sliders are respectively installed on the inner walls of the three slide grooves through three high-temperature resistant springs in a compressed state.

[0009] Preferably, a bottom plate is fixedly installed below the guide cylinder, the upper surface of the bottom plate and the lower surfaces of the three sliders are in contact with each other, and a socket for connecting a connecting pipe is provided at the center of the bottom plate.

[0010] Preferably, an externally threaded pipe is coaxially fixedly installed above the flange, and a nut for connecting the externally threaded pipe is coaxially fixedly installed on the periphery of the connecting pipe.

[0011] Preferably, an anti-scalding cover is provided above the nut, and the anti-scalding cover and the connecting pipe are coaxially fixedly connected.

[0012] Preferably, an inclined guide surface is provided on the inner side of the upper end of the sliding block.

[0013] Compared with the prior art, the present invention provides a detection instrument for the information industry, which has the following beneficial effects:

[0014] The information industry detection instrument, through the hole self-sealing component, can enable maintenance personnel to replace the instrument wiring shell and connecting pipe online without damage, that is, complete the replacement of the thermocouple detection temperature sensor online. When the damaged instrument wiring shell and connecting pipe are pulled out and removed from the flange, the three sliders in the hole self-sealing component can automatically move close to each other along the three slide grooves through three high-temperature resistant springs in a compressed state, thereby automatically sealing the socket on the bottom plate. First, it is used to ensure the sealing of the connecting equipment under the flange to avoid pressure relief inside the connecting equipment. Second, it is used to avoid the high-temperature gas in the connecting equipment under the flange from overflowing to protect maintenance personnel. Then, the connecting pipe under the new instrument wiring shell is passed downward through the hole self-sealing group. The downward moving connecting pipe can simultaneously push the three inclined guide surfaces away from each other, pass through the socket, and then the nut of the connecting pipe can be sealed and tightened on the external threaded pipe to complete the online replacement of the instrument wiring shell and connecting pipe.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0022] Reference Figure 1-4 A detection instrument for the information industry includes an instrument wiring shell 1, which is a junction box for thermocouple temperature sensing. A connecting pipe 2 is fixedly connected to the bottom of the instrument wiring shell 1, and a nut 5 is coaxially fixedly installed below the connecting pipe 2. An externally threaded pipe 8 is threadedly connected to the bottom of the nut 5. The outer diameter of the connecting pipe 2 is the same as the inner diameter of the externally threaded pipe 8. A flange 4 is coaxially fixedly installed below the externally threaded pipe 8. The flange 4 is mainly fixedly installed on the continuous production process equipment that needs to detect high temperature by bolt sealing.

[0023] In this embodiment, a hole self-sealing assembly is coaxially provided below the connecting hole in the flange 4. The hole self-sealing assembly includes a guide cylinder 6 and three sliders 11. The top of the guide cylinder 6 is fixedly installed below the flange 4. The three sliders 11 are interlocked with each other. The three sliders 11 are respectively horizontally slidably installed in the three slide grooves 9 in the guide cylinder 6. The above three slide grooves 9 are connected to each other. Figure 3 It can be seen that the three cross-connected parts of the three chute grooves 9 in the guide cylinder 6 protrude inward to limit the moving distance of the slider 11. The backs of the three sliders 11 are respectively installed on the inner walls of the three chute grooves 9 through three high-temperature resistant springs 12 in a compressed state, that is, the two ends of the high-temperature resistant springs 12 are squeezed and installed on the inner walls of the chute 9 and the slider 11;

[0024] An inclined guide surface 13 is provided on the inner side of the upper end of the slider 11, and the inclined guide surface 13 gradually tilts outward from bottom to top. A base plate 7 is fixedly installed below the guide cylinder 6. The upper surface of the base plate 7 and the lower surfaces of the three sliders 11 fit together, and the upper end surface of the slider 11 and the lower surface of the flange 4 fit together, and a socket 10 for connecting the connecting pipe 2 is provided in the center of the base plate 7.

[0025] It should be added that when the lower end of the connecting pipe 2 contacts the three inclined guide surfaces 13 of the three sliders 11 and moves downward, the downwardly moving connecting pipe 2 can simultaneously push the three inclined guide surfaces 13 away from each other until the connecting pipe 2 passes downward through the insertion hole 10 in the bottom plate 7;

[0026] When the lower end of the connecting tube 2 is pulled out from the hole self-sealing assembly, the three sliders 11 in the hole self-sealing assembly are used to automatically approach each other along the three slide grooves 9 through three high-temperature resistant springs 12 in a compressed state, thereby automatically sealing the socket 10 on the base plate 7.

[0027] In this embodiment, a scalding protection cover 3 is provided above the nut 5. The scalding protection cover 3 and the connecting pipe 2 are coaxially fixedly connected. The scalding protection cover 3 is mainly used to block the hot air coming out from below to prevent the maintenance personnel from being scalded by the hot air when the connecting pipe 2 is pulled out.

[0028] In this utility model, the process of online replacement of the information industry detection instrument is as follows:

[0029] First, unscrew the damaged instrument wiring housing 1 and connecting pipe 2 from the external threaded pipe 8 above the flange 4, and then pull the instrument wiring housing 1 and connecting pipe 2 out of the flange 4 to complete the online disassembly of the instrument wiring housing 1 and connecting pipe 2. When the lower end of the connecting pipe 2 is pulled out from the hole self-sealing component, the three sliders 11 in the hole self-sealing component are used to automatically fit together along the three slide grooves 9 through three high-temperature resistant springs 12 in a compressed state, thereby automatically sealing the socket 10 on the bottom plate 7. First, it is used to ensure the sealing of the connecting equipment below the flange 4 to avoid pressure relief inside the connecting equipment. Second, it is used to prevent the high-temperature gas in the connecting equipment below the flange 4 from overflowing, thereby preventing the maintenance personnel from being scalded by hot gas.

[0030] Then, the new instrument wiring housing 1 and connecting pipe 2 are passed downward through the hole self-sealing group through the external threaded pipe 8. When the lower end of the connecting pipe 2 contacts the three inclined guide surfaces 13 in the three sliders 11 and moves downward, the downward-moving connecting pipe 2 can simultaneously push the three inclined guide surfaces 13 away from each other until the connecting pipe 2 passes downward through the socket 10 in the base plate 7. Then, the nut 5 on the connecting pipe 2 is sealed and tightened on the external threaded pipe 8. The online replacement of the instrument wiring housing 1 and the connecting pipe 2 can be completed.

[0031] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
