Abstract
Description
Technical Field
[0001] This utility model relates to the field of liquid level gauge technology, specifically a large-diameter glass plate liquid level gauge. Background Technology
[0002] A level gauge is a tool used to measure the liquid level inside a container. Therefore, it needs to be connected to the inside of the container when in use. However, the existing standardized inner diameter value of the level gauge limits the temperature that it can measure, making it difficult to measure some high-temperature media. At the same time, because the standardized inner diameter value is relatively small, it is not accurate enough for some high-viscosity media. Therefore, a large-diameter glass plate level gauge is proposed. Utility Model Content
[0003] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.
[0004] Therefore, the technical solution adopted by this utility model is as follows:
[0005] A large-diameter glass plate level gauge includes a measuring tube, with connecting pipes extending through the upper and lower sides of the measuring tube. A connecting flange is connected to the outer side of the connecting pipe, and a cover plate is installed on the outer side of the measuring tube. A viewing window is mounted on the cover plate. A drain pipe is connected to the bottom end of the measuring tube, and a drain valve is connected to the bottom end of the drain pipe.
[0006] Preferably, a sign is provided on one side of the bottom of the cover plate.
[0007] Preferably, the inner diameter of the measuring tube is 60 mm.
[0008] Preferably, there are two connecting tubes, which are connected through each other at the top and bottom of the measuring tube.
[0009] Preferably, there are two viewing windows, each corresponding to one of the two connecting pipes.
[0010] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:
[0011] In this invention, by setting the inner diameter of the measuring tube to 60mm, which is three times the standard inner diameter of the measuring tube, it can be applied to measuring media at higher temperatures. At the same time, the three-fold inner diameter also allows for the measurement of media with higher viscosity, greatly improving the practicality of the device. Furthermore, the inclusion of a drain pipe and drain valve allows for the discharge of the first batch of media entering the measuring tube in environments with high standardization requirements, ensuring overall safety and preventing cross-contamination.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.
[0017] The following describes, with reference to the accompanying drawings, some embodiments of the large-diameter glass plate level gauge provided by this utility model.
[0018] Example:
[0019] Combination Figure 1-2 As shown, the large-diameter glass plate level gauge provided by this utility model includes a measuring tube 110 with an inner diameter of 60 mm. Two connecting pipes 120 are connected to the upper and lower sides of the measuring tube 110. The two connecting pipes 120 are connected to the top and bottom of the measuring tube 110. A connecting flange 130 is connected to the outside of the connecting pipe 120. A cover plate 140 is installed on the outside of the measuring tube 110. A sign 160 is provided on one side of the bottom of the cover plate 140. Two viewing windows 150 are installed on the cover plate 140, and the two viewing windows 150 correspond to the two connecting pipes 120 respectively. A drain pipe 170 is connected to the bottom end of the measuring tube 110, and a drain valve 180 is connected to the bottom end of the drain pipe 170.
[0020] Specifically, the sign 160 can be used to indicate the installed containers, avoiding confusion during installation, which could lead to usage errors, or even affect the quality of the medium inside the container and cause contamination, thus improving the safety of the device.
[0021] Simultaneously, two viewing windows 150 are used for measurement. The positions of the two viewing windows 150 can be aligned with the warning liquid level and the safety liquid level in the container as needed. This allows for a more direct determination of whether the liquid level in the container needs to be adjusted, such as discharge, thus improving the reliability of the device.
[0022] The working principle and usage process of this utility model are as follows: First, connect the two connecting pipes 120 to the container to be measured using the connecting flange 130, and open the drain valve 180. At this time, the air pressure balance begins, and the medium begins to enter the measuring pipe 110. The first batch of medium entering the measuring pipe 110 will be discharged to the outside. It can be used for sampling or directly discarded. After the air pressure balance is achieved, close the drain valve 180. At this time, the current liquid level will be displayed on the viewing window 150, and the measurement is completed. Finally, after use, it can be cleaned.
[0023] Although embodiments of the present invention have been shown and described, those skilled in the art will understand 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 claims and their equivalents.
