Abstract

This utility model relates to the field of liquid level gauge technology and discloses a low-density, high-pressure resistant liquid level gauge, including a measuring cylinder. Two connecting pipes are fixedly installed on the front end face of the measuring cylinder. An adsorption mechanism is fixedly installed on the upper end face of one of the two connecting pipes. A glass plate is fixedly installed on the front end face of the measuring cylinder. A first outer shell is fixedly installed on the rear end face of the measuring cylinder. A fixing mechanism is fixedly installed between the first outer shell and the measuring cylinder. A cleaning mechanism is slidably connected to the outside of the first outer shell. By installing an adsorption device on the upper end of the connecting pipe, iron filings in the liquid are adsorbed by a magnetic block inside the adsorption device, thereby effectively preventing iron filings from entering the measuring cylinder through the connecting pipe.

Description

Technical Field

[0001] This utility model relates to the field of liquid level gauge technology, specifically a low-density, high-pressure resistant liquid level gauge. Background Technology

[0002] Low-density, high-pressure resistant level gauges are instruments used for the accurate measurement of low-density liquid levels, particularly suitable for high-pressure environments. These level gauges are designed to withstand high-pressure operating conditions while providing accurate measurements of low-density media, such as gases or volatile liquids.

[0003] Most traditional steel and other metal containers contain iron. When liquids are stored for a long time, the inside of the container will corrode to varying degrees, producing a small amount of iron filings. During the use of the level gauge, the iron filings may be attracted to the surface of the magnetic float, changing the mass of the magnetic float and affecting the accuracy of the measurement. At the same time, the level gauge is exposed to the outside for a long time during use, so a lot of dust may accumulate on the surface, affecting the readings of the operator. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a low-density, high-pressure resistant liquid level gauge, which has the advantages of strong practicality and good cleaning effect, thus solving the problems mentioned in the background technology.

[0005] This utility model provides the following technical solution: a low-density, high-pressure resistant liquid level gauge, comprising a measuring cylinder, two connecting pipes fixedly installed on the front end face of the measuring cylinder, an adsorption mechanism fixedly installed on the upper end face of one of the two connecting pipes, a glass plate fixedly installed on the front end face of the measuring cylinder, a first outer shell fixedly installed on the rear end face of the measuring cylinder, a fixing mechanism fixedly installed between the first outer shell and the measuring cylinder, a drain valve fixedly installed on the lower end face of the measuring cylinder, sliding grooves opened on both sides of the first outer shell, a cleaning mechanism slidably connected to the outer side of the first outer shell, a protective spring fixedly installed on the inner top surface of the measuring cylinder, and a magnetic float slidably connected inside the measuring cylinder.

[0006] As a preferred technical solution of this utility model, multiple magnetic flip plates are rotatably installed on the rear end face of the first outer shell, and the rear end face of the first outer shell is provided with a scale.

[0007] As a preferred embodiment of this utility model, the fixing mechanism includes a fixing ring, an elastic block is fixedly installed on the rear end face of the fixing ring, and a No. 1 fixing bolt is threadedly connected to both sides of the fixing ring.

[0008] As a preferred technical solution of this utility model, the cleaning mechanism includes two sliders, each of the rear end faces of the two sliders is fixedly mounted with a No. 1 connecting block, the two No. 1 connecting blocks are snapped together with a No. 1 mounting plate, the rear end face of the No. 1 mounting plate is threadedly connected with two No. 2 fixing bolts, and the front end face of the No. 1 mounting plate is fixedly mounted with a cleaning block.

[0009] As a preferred embodiment of this utility model, the adsorption mechanism includes a second outer shell, a second mounting plate is snapped onto the upper surface of the second outer shell, a sealing ring is fixedly installed on the lower surface of the second mounting plate, a magnetic block is fixedly installed on the lower surface of the second mounting plate, and a handle is fixedly installed on the upper surface of the second mounting plate.

[0010] As a preferred technical solution of this utility model, a second connecting block is fixedly installed on both sides of the second outer shell, and a threaded rod is threadedly connected to the upper end face of each of the two second connecting blocks, and a limit block is fixedly installed on the upper end face of each of the two threaded rods.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This low-density, high-pressure resistant liquid level gauge uses an adsorption device installed at the upper end of the connecting pipe. The magnetic block inside the adsorption device adsorbs iron filings in the liquid, effectively preventing iron filings from entering the measuring cylinder through the connecting pipe. This avoids the iron filings being attracted by the magnetic float and affecting the measurement results. After the liquid level gauge has completed the measurement, the position of the limiting block can be rotated, and the magnetic block can be removed by the handle to clean the iron filings adsorbed on the surface of the magnetic block.

[0013] 2. This low-density, high-pressure resistant level gauge features a cleaning mechanism that slides on the outside of the second housing. When the scale at the rear of the second housing becomes unreadable due to the accumulation of dust and dirt, the cleaning block can be cleaned by sliding the first mounting plate up and down, ensuring accurate readings for the operator. If the cleaning effect of the cleaning block deteriorates, it can be replaced by removing the second fixing bolt to maintain the cleaning effect of the cleaning mechanism.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-6 A low-density, high-pressure resistant liquid level gauge includes a measuring cylinder 3. Two connecting pipes 1 are fixedly installed on the front end face of the measuring cylinder 3. An adsorption mechanism 8 is fixedly installed on the upper end face of one of the two connecting pipes 1. A glass plate 2 is fixedly installed on the front end face of the measuring cylinder 3. A first outer shell 5 is fixedly installed on the rear end face of the measuring cylinder 3. A fixing mechanism 4 is fixedly installed between the first outer shell 5 and the measuring cylinder 3. A drain valve 9 is fixedly installed on the lower end face of the measuring cylinder 3. Sliding grooves 6 are opened on both sides of the first outer shell 5. A cleaning mechanism 7 is slidably connected to the outside of the first outer shell 5. A protective spring 10 is fixedly installed on the top inner surface of the measuring cylinder 3. A magnetic float 11 is slidably connected inside the measuring cylinder 3. Multiple magnetic flip plates 13 are rotatably installed on the rear end face of the first outer shell 5. A scale 12 is opened on the rear end face of the first outer shell 5.

[0023] In the above structure, the measuring cylinder 3 and the liquid storage container are connected by the connecting pipe 1. The adsorption mechanism 8 adsorbs iron filings in the liquid to be tested, preventing the iron filings from being adsorbed on the surface of the magnetic float 11 and affecting the measurement results of the liquid level gauge. When the magnetic float 11 is pushed upward by the liquid to be tested, it will drive the magnetic flip plate 13 to reverse. Then, the operator can read the measurement result according to the number of times the magnetic flip plate 13 flips and the scale 12. When the scale 12 is contaminated by dust and dirt and cannot be read, it can be cleaned by the cleaning mechanism 7 to ensure that the operator can read the value accurately.

[0024] In a preferred embodiment, the fixing mechanism 4 includes a fixing ring 401, an elastic block 402 is fixedly installed on the rear end face of the fixing ring 401, and a fixing bolt 403 is threadedly connected to both sides of the fixing ring 401.

[0025] In the above structure, the first outer shell 5 is fixed to the outside of the measuring cylinder 3 by the fixing ring 401 and the first fixing bolt 403. The elastic block 402 can both protect the measuring cylinder 3 and increase the friction and the fixing effect.

[0026] In a preferred embodiment, the cleaning mechanism 7 includes two sliders 701, with a first connecting block 702 fixedly installed on the rear end face of each slider 701, a first mounting plate 704 snapped between the two first connecting blocks 702, two second fixing bolts 703 threadedly connected to the rear end face of the first mounting plate 704, and a cleaning block 705 fixedly installed on the front end face of the first mounting plate 704.

[0027] In the above structure, by sliding the first mounting plate 704, the slider 701 and the inside of the groove 6 are driven to slide up and down, so that the cleaning block 705 can clean dust and stains, so that the staff can read the reading accurately and ensure the accuracy of the liquid level gauge measurement results.

[0028] In a preferred embodiment, the adsorption mechanism 8 includes a second outer shell 801, a second mounting plate 806 is snapped onto the upper end face of the second outer shell 801, a sealing ring 807 is fixedly installed on the lower end face of the second mounting plate 806, a magnetic block 805 is fixedly installed on the lower end face of the second mounting plate 806, a handle 808 is fixedly installed on the upper end face of the second mounting plate 806, and second connecting blocks 803 are fixedly installed on both sides of the second outer shell 801. Threaded rods 804 are threadedly connected to the upper end faces of the two second connecting blocks 803, and limit blocks 802 are fixedly installed on the upper end faces of the two threaded rods 804.

[0029] In the above structure, the magnetic block 805 inside the adsorption mechanism 8 adsorbs iron filings in the liquid, thereby preventing iron filings from entering the measuring cylinder 3 and affecting the measurement results of the level gauge. By rotating the limiting block 802, the position of the magnetic block 805 can be fixed. With the help of the sealing ring 807, liquid leakage can be prevented during the measurement process. After the measurement is completed, the magnetic block 805 can be removed by the handle 808 for cleaning, ensuring the adsorption effect of the adsorption mechanism 8.

[0030] The working principle is to adsorb iron filings in the liquid by installing an adsorption mechanism 8 at the upper end of the connecting pipe 1, so as to prevent iron filings from entering the measuring cylinder 3 and affecting the measurement results of the hydraulic gauge. When there is dust or dirt on the surface of the scale 12 and the reading cannot be read, the first mounting plate 704 can be slid up and down to allow the cleaning block 705 to clean it, so that the staff can accurately read the measurement results.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
