Description

Technical Field

[0001] The utility model relates to the technical field of float level gauges, in particular to a vacuum heat insulation type float level gauge. Background Art

[0002] The float level gauge is a liquid level measuring instrument designed based on Archimedes' principle and the principle of magnetic coupling. Its working principle is to measure the liquid level through the interaction of components such as the float, lever, torque tube, and gauge shaft. When the liquid level is lower than the float, the entire weight of the float acts on the lever, causing the torque tube to produce the maximum torsion angle, which is the zero position of the instrument; when the liquid level is higher than the lower end of the float, the force acting on the lever becomes the difference between the float's gravity and the float's buoyancy; as the liquid level gradually rises, the torque moment gradually decreases, and the torsion angle generated by the torque tube also decreases accordingly. The pointer is driven by a mechanical transmission amplification mechanism to display the liquid level. The vacuum insulation float level gauge is a jacket installed at the outer end of the cylinder, and a vacuum treatment is performed to ensure the temperature insulation of the internal medium.

[0003] In the existing float level gauge, when the float inside the cylinder is disassembled for comprehensive cleaning, the torque tube and display at the upper end of the float must be removed first before the float can be removed. Since the torque tube and display are large and inconvenient to disassemble, it is also inconvenient to remove the float separately and easily for comprehensive cleaning and maintenance. Therefore, we propose a vacuum insulated float level gauge. Utility Model Content

It should be noted that the embodiments of the present invention and the features therein can be combined with each other unless there is any conflict.

[0024] The following describes the vacuum insulation float level gauges provided by some embodiments of the present invention with reference to the accompanying drawings.

[0026] Combine Figure 1-5 As shown, the vacuum heat-insulated float level gauge provided by the present invention includes: a float level gauge device 100, and a disassembly assembly 200; the float level gauge device 100 includes an outer cylinder 101 at the bottom, a torque tube 102 installed at the upper end of the outer cylinder 101, a jacket 103 fixedly installed at the outer end of the outer cylinder 101, and a vacuum joint 104 fixedly installed on one side of the jacket 103; the disassembly assembly 200 includes a float 201 movably installed in the outer cylinder 101, a torsion rod 202 connected in the torque tube 102, a disassembly opening 203 opened at the top of the outer cylinder 101, a sealing screw 204 movably installed in the disassembly opening 203, a connecting rod 205 fixedly installed on the top of the float 201, and a fixing screw 204 fixed on the top of the connecting rod 205. The installed mounting piece 206, the threaded mounting seat 207 fixedly installed at the front end of the torsion bar 202, the stud 208 movably installed in the mounting piece 206, the top of the stud 208 is also fixedly installed with an adjustment plate 209, the upper end of the torsion bar 202 is also fixedly installed with a plug 210, and both sides of the plug 210 are also fixedly installed with positioning protrusions 211, and the mounting piece 206 is also provided with a positioning slot 212, and the positioning slot 212 is integrally matched with the plug 210 and the positioning protrusion 211, the outer end of the stud 208 on the upper part of the mounting piece 206 is also fixedly installed with a restraining piece 213, and the outer end of the restraining piece 213 is also movably covered with a restraining cover 214, and the bottom of the restraining cover 214 is fixed on the mounting piece 206.

[0027] Specifically, the float level gauge is a liquid level measuring instrument designed based on Archimedes' principle and magnetic coupling principle. The vacuum insulation float level gauge is a type of float level gauge in which a jacket 103 is installed at the outer end of the cylinder and a vacuum treatment is performed to ensure the temperature insulation of the internal medium. In this float level gauge device 100, the outer cylinder 101 and the torque tube 102 are connected inside, and the connection structure between the top mounting plate 206 of the float 201 and the torsion bar 202 can be adjusted by rotating the top adjustment plate 209 of the stud 208. Adjustment is performed to realize quick disassembly of the buoy 201 in the outer cylinder 101, so that the buoy 201 in the outer cylinder 101 can be easily and conveniently taken out separately through the disassembly opening 203 at the top of the outer cylinder 101, so as to fully clean the buoy 201 and clean the attachments stuck on the outer end of the buoy 201 to ensure its measurement accuracy. In addition, the quick disassembly structure of the buoy 201 in the disassembly opening 203 at the top also makes it unnecessary to disassemble the torque tube 102 as a whole, thereby improving the convenience of disassembling the buoy 201. At the same time, the positioning slot 212 opened at the upper end of the mounting piece 206 also allows the buoy 201 to be quickly positioned and snap-fitted to the outer end of the plug 210 and the positioning protrusion 211 on the upper part of the torsion bar 202 when it is installed after cleaning. Then, the stud 208 at the bottom is rotated by the adjusting plate 209 to fix the mounting piece 206 on the top of the buoy 201 to the upper end of the torsion bar 202, ensuring the accuracy and convenience of the installation of the buoy 201 after cleaning. The sealing screw 204 installed in the disassembly and assembly port 203 is mainly used for the installation of the buoy 201. It is used for sealing and fixing the disassembly and assembly port 203 when it is not in use. The threaded mounting seat 207 fixedly installed at the front end of the torsion bar 202 is mainly used for positioning and fixing the stud 208 in the mounting piece 206. The adjustment plate 209 on the top of the stud 208 is mainly used for rotational adjustment of the mounting piece 206 during assembly and disassembly, and can also facilitate pulling the mounting piece 206 after disassembly. The restraining piece 213 and the stud 208 installed in the restraining cover 214 on the mounting piece 206 are mainly used for position restraint of the stud 208.

[0028] The working principle and use process of this utility model:

[0029] When the float 201 in the float level gauge device 100 is disassembled and cleaned separately, the sealing screw 204 on the top of the outer cylinder 101 is first unscrewed. After the sealing screw 204 is removed, the adjustment plate 209 on the top of the outer cylinder 101 is rotated through the disassembly port 203. After the adjustment plate 209 rotates, the stud 208 rotates synchronously and gradually disengages from the threaded mounting seat 207 at the front end of the torsion bar 202. After the stud 208 is unscrewed from the threaded mounting seat 207, the adjustment plate 209 can be pulled to remove the mounting piece 206 and the bottom of the float 201 separately from the outer cylinder 101 for comprehensive cleaning and maintenance of the float 201. After the comprehensive cleaning and maintenance of the float 201 is completed, it can be disassembled and reassembled. The opening 203 is inserted, and by moving the adjustment plate 209, the positioning slot 212 in the lower mounting piece 206 is installed to the plug 210 and the outer end of the positioning protrusion 211 on the torsion bar 202, so as to perform the positioning installation after the mounting piece 206 is disassembled. After the positioning slot 212 is fully engaged with the plug 210 and the outer end of the positioning protrusion 211, the adjustment plate 209 can be rotated to unscrew the bottom stud 208, so as to re-fix the stud 208 to the threaded mounting seat 207 at the front end of the torsion bar 202, thereby completing the installation and fixation of the float 201 after cleaning. After installing the sealing screw 204 in the disassembly opening 203, the float level gauge device 100 can be used.

[0030] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
