Description

Technical Field

[0001] The utility model relates to the technical field of bimetallic thermometer installation, in particular to a tank thermometer installation structure. Background Art

[0002] Existing tank structures generally use bimetallic thermometers for temperature monitoring. The bimetallic thermometer uses a spirally wound thermal bimetallic strip as a temperature sensing device and installs it in a protective sleeve. One end is fixed, called the fixed end, and the other end is connected to a thin shaft, called the free end. A pointer is installed on the free end spool. When the temperature changes, the free end of the temperature sensing device rotates accordingly, driving the pointer on the thin shaft to produce an angle change, indicating the corresponding temperature on the dial.

[0003] In order to meet the needs of actual production, the bimetallic thermometer has different installation and fixing forms: movable external thread pipe joint, movable internal thread pipe joint, fixed thread and ferrule thread joint, ferrule flange joint and fixed flange, which are easy to install and operate;

[0004] When installing a bimetallic thermometer, you need to pay attention to the following issues:

[0005] (1) In order to ensure sufficient heat exchange between the measuring end of the thermal resistor and the measured medium, the measuring point should be reasonably selected, and the thermal resistor should be installed as far as possible to avoid being installed near valves, elbows, pipes and equipment dead corners;

[0006] (2) Thermal resistors with protective sleeves have heat transfer and heat dissipation losses. In order to reduce measurement errors, thermocouples and thermal resistors should have sufficient insertion depth;

[0007] The existing bimetallic thermometer has a fixed installation depth, that is, the insertion depth of the bimetallic thermometer at the same installation position is fixed. However, during actual installation, due to different monitoring points, the bimetallic thermometer has different insertion depth installation requirements. The bimetallic thermometer with a fixed insertion depth has weak versatility. Based on this, a tank thermometer installation structure is provided. Utility Model Content

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] See also Figures 1 to 4 In an embodiment of the present invention, a tank thermometer mounting structure includes a bimetallic thermometer 1 consisting of a dial 101 and a protective sleeve 102, and a fixed nut seat 2. The protective sleeve 102 is fixed to the bottom of the dial 101, and the fixed nut seat 2 is welded and fixed to the tank mounting position. An adjustable mounting component 3 is provided on the outside of the protective sleeve 102. The adjustable mounting component 3 is used to achieve different insertion depths of the bimetallic thermometer 1.

[0034] The adjustable mounting assembly 3 includes a mounting unit and an adjustment unit;

[0035] The mounting unit is used to be threadedly connected to the fixed nut seat 2, so as to achieve the installation and fixation of the bimetallic thermometer 1 and the tank body;

[0036] The adjustment unit is used to adjust and fix the relative height position between the installation unit and the protective sleeve 102, thereby adjusting the depth of the protective sleeve 102 inserted into the tank body;

[0037] The mounting unit includes a Chinese-shaped sleeve 301, a limiting ring groove 304, a hexagonal rotating seat 308, a rotating ring groove 309, a mounting screw 310, a conical pressing groove 311, and a second I-shaped rubber seat 312;

[0038] The Chinese-shaped sleeve 301 is slidably sleeved on the outside of the protective sleeve 102, the limiting ring groove 304 is formed on the outside of the annular protrusion of the Chinese-shaped sleeve 301, the rotating ring groove 309 is formed on the inside of the hexagonal rotating seat 308, and the mounting screw 310 is fixed to the bottom of the hexagonal rotating seat 308. The hexagonal rotating seat 308 and the mounting screw 310 are rotatably connected to the Chinese-shaped sleeve 301 through the sleeve engagement of the rotating ring groove 309 and the limiting ring groove 304;

[0039] The bottom of the mounting screw barrel 310 extends and protrudes below the Chinese-shaped sleeve 301, and a conical groove 311 is formed on the inner bottom of the mounting screw barrel 310. The second I-shaped rubber seat 312 is distributed inside the conical groove 311 and is sleeved with the outer wall of the protective sleeve 102. The bottom of the second I-shaped rubber seat 312 extends and protrudes below the mounting screw barrel 310;

[0040] When the protective sleeve 102 is inserted into the tank body through the fixed nut seat 2, the mounting screw barrel 310 is threadedly connected to the fixed nut seat 2 and tightened. The second I-shaped rubber seat 312 is squeezed by the fixed nut seat 2 and moves upward along the inclined inner wall of the conical pressing groove 311 and shrinks to fit tightly against the outer wall of the protective sleeve 102, thereby achieving the installation, fixation and sealing of the bimetallic thermometer 1.

[0041] The adjustment unit includes an external thread 302, an inverted conical pressing groove 303, a first I-shaped rubber seat 305, a fastening nut 306, and a hexagonal block 307;

[0042] The external thread 302 is formed on the outer top of the Chinese-shaped sleeve 301, and the inverted conical groove 303 is opened on the inner top of the Chinese-shaped sleeve 301. The first I-shaped rubber seat 305 is distributed inside the inverted conical groove 303 and is sleeved on the outer wall of the protective sleeve 102. The top of the first I-shaped rubber seat 305 extends and protrudes above the Chinese-shaped sleeve 301.

[0043] The hexagonal block 307 is fixed to the outer top of the fastening nut 306. The fastening nut 306 and the hexagonal block 307 are integrally sleeved on the outer side of the protective sleeve 102. The fastening nut 306 is threadedly connected to the external thread 302 and squeezes the first I-shaped rubber seat 305 downward and shrinks, so that the first I-shaped rubber seat 305 is tightly fitted to the outer wall of the protective sleeve 102 to achieve the relative position fixation of the Chinese-shaped sleeve 301 and the protective sleeve 102.

[0044] The inner diameter of the conical groove 311 increases from top to bottom. The top of the inner wall of the conical groove 311 is flush with the bottom of the Chinese-shaped sleeve 301, and the diameter of the top of the inner wall of the conical groove 311 is larger than the outer diameter of the Chinese-shaped sleeve 301.

[0045] The outer side of the top annular portion of the second I-shaped rubber seat 312 is a tapered structure, and the outer wall inclination angle of the tapered structure matches the inner wall inclination angle of the tapered groove 311. The outer wall diameter of the bottom annular portion of the second I-shaped rubber seat 312 matches the inner wall diameter of the fixing nut seat 2, and the central aperture of the second I-shaped rubber seat 312 matches the outer wall of the protective sleeve 102.

[0046] The inner wall diameter of the inverted conical groove 303 increases from bottom to top. The outer side of the bottom annular portion of the first I-shaped rubber seat 305 is in an inverted conical structure, and the inclination angle of the outer wall of the inverted conical structure matches the inclination angle of the inner wall of the inverted conical groove 303.

[0047] The outer diameter of the annular portion at the top of the first I-shaped rubber seat 305 matches the inner diameter of the fastening nut 306 , and the central hole diameter of the first I-shaped rubber seat 305 matches the outer wall of the protective sleeve 102 .

[0048] In this embodiment, the bimetallic thermometer 1 is installed in the following steps:

[0049] The first I-shaped rubber seat 305 is manually pulled upward to release the mutual squeezing between the first I-shaped rubber seat 305 and the inverted conical groove 303. The first I-shaped rubber seat 305 is reset to its initial state under the action of its own elastic force. At this time, the first I-shaped rubber seat 305 and the protective sleeve 102 are released from the squeezed and fitted state. Similarly, the second I-shaped rubber seat 312 is pulled downward to release the squeezed and fitted state with the protective sleeve 102. At this time, the bimetallic thermometer 1 can be moved as a whole to adjust the position of the I-shaped sleeve 301 on the protective sleeve 102.

[0050] After the position of the Chinese-shaped sleeve 301 is determined, the fastening nut 306 is threadedly connected to the external thread 302 and tightened. The fastening nut 306 squeezes the first I-shaped rubber seat 305 downward. When the first I-shaped rubber seat 305 moves downward relative to the Chinese-shaped sleeve 301, it is squeezed by the inner wall of the inverted conical pressing groove 303 and deforms and shrinks. The shrunken first I-shaped rubber seat 305 fits tightly with the protective sleeve 102. The relative position of the Chinese-shaped sleeve 301 and the protective sleeve 102 can be fixed by the friction between the first I-shaped rubber seat 305 and the protective sleeve 102.

[0051] When the screw barrel 310 is screwed to the fixing nut seat 2 and the screw barrel 310 is screwed to the fixing nut seat 2, the second I-shaped rubber seat 312 is subjected to the extrusion force from the bottom of the fixing nut seat 2. This extrusion force can make the second I-shaped rubber seat 312 move upward relative to the middle-shaped sleeve 301. During this process, the second I-shaped rubber seat 312 is simultaneously subjected to the extrusion force from the inclined surface of the conical pressing groove 311 to shrink. The shrinking second I-shaped rubber seat 312 fits tightly against the outer wall of the protective sleeve 102, which not only further improves the relative fixing force between the middle-shaped sleeve 301 and the protective sleeve 102, but also provides a good sealing effect between the protective sleeve 102 and the fixing nut seat 2.

[0052] By cooperating with the above multiple parts, the bimetallic thermometer 1 can be installed at different depths, which effectively improves the versatility of the bimetallic thermometer 1 (it should be noted that the bimetallic thermometer 1 is a common bimetallic thermometer on the market, and its working principle technology is mature, so it will not be elaborated here).

[0053] Please refer to Figures 1 to 4 The inner diameter of the hexagonal swivel seat 308 is larger than the outer wall diameter of the fastening nut 306 .

[0054] In this embodiment: this structure can ensure that the fastening nut 306 will not come into contact with the hexagonal swivel seat 308 when the external thread 302 is fully tightened. In this way, when the hexagonal swivel seat 308 and the mounting screw barrel 310 are rotated and tightened or loosened as a whole by a tool, the connection between the fastening nut 306 and the external thread 302 will not be affected.

[0055] 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.
