Abstract
Description
Technical Field
[0001] The utility model relates to the relevant field of float ball liquid level gauges, in particular to a float ball liquid level gauge. Background Art
[0002] The float level meter uses a magnetic float as a measuring element. Through magnetic coupling, the resistance in the sensor changes linearly. The intelligent converter converts the resistance change into a 4~20mA standard current signal. The percentage of the liquid level, 4~20mA current and liquid level value can be displayed on site. Remote transmission to the control room can realize automatic detection, control and recording of the liquid level. The float level meter consists of a float, a rod, etc. It is designed based on the Archimedes buoyancy principle.
[0003] There are still certain deficiencies in the use of float level gauges in the prior art. The plug rods on traditional float level gauges are usually directly inserted and fixed in the center of the float, and the float is usually welded with two hemispherical bodies, so there will be welding marks on the surface of the float. Since the float is immersed in liquid for a long time, the welding point will be corroded to a certain extent, resulting in rust, making the float and the plug rod become awkward. In severe cases, the float is stuck, and the limiting structures on the commonly used plug rods are directly welded to the plug rod. The maximum height of the float can only be limited to one, and the use process has certain limitations. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a float level gauge, comprising a float level gauge body and a floating block, an insertion rod is provided at the bottom of the float level gauge body, a connecting flange is provided at the upper end of the outer ring of the insertion rod, guide rails are provided on both sides of the surface of the insertion rod, the floating block is connected to the guide rails through guide sliders and is arranged on the insertion rod, a right half-end bracket and a left half-end bracket are respectively provided on both sides of the floating block, a right float is provided at the lower part of the interior of the right half-end bracket, a left float is provided at the lower part of the interior of the left half-end bracket, an upper limit plate is provided at the upper end of the interior of the guide rail, a lower limit plate is provided at the lower end of the interior of the guide rail, and the lower limit plate is arranged above the bottom sealing cover.
[0006] In a further embodiment, the upper limit plate and the guide rail are fixedly connected via upper fixing screws and upper fixing screw holes, and there are two groups of upper fixing screw holes, and each group has no less than two.
[0007] In a further embodiment, the lower limit plate and the guide rail are fixedly connected via lower fixing screws and lower fixing screw holes, and there are two groups of lower fixing screw holes, and each group has no less than two screw holes.
[0008] In a further embodiment, the bottom sealing cover is inlaid and connected to the insertion rod via an inner sealing plug, and the cross section of the bottom sealing cover is set to a semicircular structure.
[0009] In a further embodiment, the left float is welded to the left half-end bracket, the right float is welded to the right half-end bracket, and the left float and the right float are configured as a centrally symmetrical structure.
[0010] In a further embodiment, the lower limiting plate and the bottom sealing cover are configured as an integral structure, and the lower limiting plate and the bottom sealing cover are connected to form a U-shaped structure.
[0011] Compared with the prior art, the beneficial effects of the utility model are:
[0012] The utility model divides a traditional float into two small floats, namely a left float and a right float. The center position of the float cannot have a socket reserved, but can be directly processed into a whole, so that the surface of the float is flat and smooth without joints, and the material is more corrosion-resistant and rust-free. The floats are arranged on both sides to increase the balance, so that the floating block has a good balanced floating state, and the floating block and the plug rod are connected with the guide slide rail through the guide slider and the guide slide rail. The guide slide rail can be used to locate the position of the guide slider moving up and down, so that the floating position of the floating block is always consistent, preventing the floating position from being offset, tilted, etc., avoiding the floating block from being stuck, and increasing the accuracy of measurement.
[0013] The utility model provides an upper limit plate at the upper end of the inner part of the guide slide rail, through which the maximum floating height of the float can be limited and positioned, and the upper limit plate is disassembled and fixed by screws. The upper limit plates of different lengths can be replaced according to the needs of use to meet the needs of different height restrictions, thereby increasing the flexibility of use.
