AI Technical Summary
Existing level gauge floats are prone to impacting the inner wall of the level gauge housing when subjected to bumps, and prolonged impact on the same spot can lead to leakage.
A structure was designed in which a float can rotate around a detection link. A guide sleeve is set in the middle of the float, and a lubricating bushing and a limiting plate are on the outer wall of the detection link. The guide sleeve contacts the lubricating bushing, and the limiting plate restricts the range of rotation of the float to avoid bumping the same position for a long time.
The rotating design of the float avoids prolonged contact between the float and the level gauge housing, reducing the risk of leakage and improving the durability and reliability of the equipment.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of level gauges, specifically to a level gauge float. Background Technology
[0002] Currently, the float of existing level gauges is fixed to the bottom of the detection link. When the level gauge is bumped, the float is prone to hitting the inner wall of the level gauge housing. If the same position is hit for a long time, leakage is likely to occur. There is a lack of a level gauge float that can avoid hitting the same position. Utility Model Content

[0004] This invention includes a detection link and a float. The float is movably installed at the bottom of the detection link and can rotate around the detection link.
[0005] A guide sleeve is provided in the middle of the float, and the guide sleeve is fitted onto the bottom of the detection link.
[0006] A set of lubricating bushings is provided on the outer wall of the detection link. When the float rotates, the inner wall of the guide sleeve contacts the lubricating bushings.
[0007] A pair of limiting plates are provided at the bottom of the detection link, and the lubrication bushing is located between the pair of limiting plates.
[0008] The limiting plate is welded to the outer wall of the detection link.
[0009] The guide sleeve is welded inside the float, and a hollow area is formed between the outer wall of the guide sleeve and the inner wall of the float.
[0010] The lubrication bushing is a polytetrafluoroethylene (PTFE) bushing.
[0011] The number of lubrication bushings in a set is two.
[0012] The limiting piece is an annular limiting piece, and the diameter of the limiting piece is larger than the diameter of the guide sleeve.
[0013] The advantages of this invention are: the float can rotate around the detection link, avoiding prolonged contact with the same position and preventing leakage. Attached Figure Description

[0021] As shown in the attached figure, the present invention includes a detection link 1 and a float 2. The float 2 is movably installed at the bottom of the detection link 1 and can rotate around the detection link 1.
[0022] A guide sleeve 3 is provided in the middle of the float 2, and the guide sleeve 3 is fitted onto the bottom of the detection link 1.
[0023] A set of lubrication bushings 4 is provided on the outer wall of the detection link 1. When the float 2 rotates, the inner wall of the guide sleeve 3 contacts the lubrication bushings 4.

[0029] The limiting piece 5 is an annular limiting piece, and the diameter of the limiting piece 5 is larger than the diameter of the guide sleeve 3.
[0030] Example 1: The installation process of float 2 is as follows: first, weld the upper limiting plate 5, install a set of lubrication bushings 4 on the outer wall of the detection link 1, put the guide sleeve 3 in the middle of float 2 on the detection link 1, and finally weld the lower limiting plate 5.
[0031] In use, the float 2 rotates around the detection link 1. A set of lubrication bushings 4 provides lubrication, making the rotation of the float 2 smoother. The float 2 is located between a pair of limit plates 5 to prevent the float 2 from moving up and down when rotating.
