Abstract
Description
A float level gauge with a pressure-resistant structure Technical Field
[0001] This utility model relates to the field of float level gauge technology, specifically a float level gauge with a pressure-resistant structure. Background Technology
[0002] The float level gauge uses a magnetic float as the measuring element. Through magnetic coupling, the resistance inside the sensor changes linearly. The intelligent converter converts the resistance change into a 4-20mA standard current signal. It can display the percentage of liquid level, 4-20mA current and liquid level value on site, and transmit the data to the control room to realize the automatic detection, control and recording of liquid level.
[0003] Currently, in practical applications, float level gauges are subject to pressure when the internal pressure of the measured liquid is too high, as the pressure inside the liquid is uncertain. This pressure can cause the surface of the float level gauge to be squeezed and damaged. Summary of the Invention
[0004] The purpose of this invention is to provide a float level gauge with a pressure-resistant structure to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a float level gauge with a pressure-resistant structure, comprising:
[0006] The instrument has a vertical rod fixed to its bottom, a lifting block on its surface, an extension plate fixed to its surface, a screw ring and a threaded ring inside the extension plate, an elastic plate on its surface, and a rubber sheet on its surface.
[0007] Preferably, the lifting block is located on the surface of the vertical rod, and the lifting block can move up and down on the surface of the vertical rod. Two sets of extension plates are fixed to the top of the lifting block.
[0008] Preferably, the top surface of the extension plate is provided with threads, the threaded ring is threaded onto the surface of the extension plate, the screw ring is fixed on the top of the threaded ring, and both the screw ring and the threaded ring can be raised and lowered on the surface of the vertical rod.
[0009] Preferably, a plug ring is inserted into the bottom of the screw ring, the plug ring is rotatable on the surface of the screw ring, and a limiting ring is provided at the end of the plug ring, the limiting ring being located inside the screw ring.
[0010] Preferably, a lifting rod is fixed to the bottom of the insertion ring, and a push block is fixed to the bottom of the lifting rod, with the push block located inside the lifting block.
[0011] Preferably, the lifting block is provided with a spring inside, one end of the spring is connected to the surface of the elastic plate, and the other end is connected to the inside of the lifting block.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] This invention proposes that when the liquid pressure is high, the elastic plate, due to its elasticity, is squeezed into the interior of the lifting block, allowing the internal pressure of the lifting block to adapt to the external pressure, and the spring is compressed. After the lifting block is removed, the elastic plate returns to its original shape under the push of the spring. If the elastic plate cannot return to its original shape, the screw ring is turned, causing the screw ring to descend. The top surface of the extension plate is threaded. When the screw ring moves to the bottom of the extension plate, it is no longer screwed onto the surface of the extension plate. The screw ring moves down, and through the lifting rod, it drives the push block to move down. The push block holds the surface of the elastic plate, causing the elastic plate to return to its original shape. Attached Figure Description

[0020] Please refer to Figures 1 to 4. This utility model provides a technical solution: a float level gauge with a pressure-resistant structure, comprising: an instrument 1, a vertical rod 3 fixed to the bottom of the instrument 1, a lifting block 2 disposed on the surface of the vertical rod 3, a spring 11 disposed inside the lifting block 2, one end of the spring 11 connected to the surface of an elastic plate 7, and due to the elasticity of the elastic plate 7, the elastic plate 7 is squeezed into the interior of the lifting block 2, so that the pressure inside the lifting block 2 adapts to the external pressure, and the other end is connected to the interior of the lifting block 2. The lifting block 2 is located on the surface of the vertical rod 3 and can move up and down on the surface of the vertical rod 3. Two sets of extension plates 5 are fixed to the top of the lifting block 2, and the top surface of the extension plates 5 is provided with threads. A screw ring 13 is screwed onto the surface of the extension plates 5. Tightening the screw ring... 4. This causes the screw ring 13 to descend. The top surface of the extension plate 5 is provided with threads. When the screw ring 13 moves to the bottom of the extension plate 5, the screw ring 13 is no longer screwed to the surface of the extension plate 5. The screw ring 4 is fixed to the top of the screw ring 13, and both the screw ring 4 and the screw ring 13 can rise and fall on the surface of the vertical rod 3.

[0021] When the float level gauge is in use, the vertical rod 3 and the lifting block 2 are located in the liquid. The lifting block 2 floats on the top of the liquid. When the liquid pressure is high, due to the elasticity of the elastic plate 7, the elastic plate 7 is squeezed into the interior of the lifting block 2, so that the pressure inside the lifting block 2 adapts to the external pressure, and the spring 11 is compressed. After the lifting block 2 is removed, the elastic plate 7 returns to its original shape under the push of the spring 11. If the elastic plate 7 cannot return to its original shape, the screw ring 4 is turned so that the screw ring 13 descends. The top surface of the extension plate 5 is provided with threads.
