Description

Technical Field

[0001] This utility model belongs to the field of liquid level detection technology, and in particular relates to a stainless steel panel magnetic flip liquid level gauge. Background Technology

[0002] The stainless steel panel magnetic level gauge is a magnetic level gauge made of stainless steel panel. The magnetic level gauge uses the principle of magnetism to display the liquid level by the change of the flip plate. It has the advantages of high accuracy, strong stability and long service life. It is based on the principle of magnetic coupling and consists of a conduit with a magnetic float and multiple flip plates. In actual operation, the magnetic float moves up and down in the conduit as the liquid level changes, and the magnet inside the float will drive the flip plates outside the conduit to flip accordingly, so as to intuitively display the height of the liquid level. The existing stainless steel panel magnetic level gauge is fixed to the installation platform by a flange. However, the position of the flange and the conduit cannot be adjusted, which makes it inconvenient to install the stainless steel panel magnetic level gauge vertically, thus affecting the measurement accuracy of the stainless steel panel magnetic level gauge. In addition, the bottom of the conduit is equipped with a flange with a drain valve. This flange is fixed to the conduit by multiple bolts. However, when cleaning the inside of the conduit, multiple bolts need to be disassembled and reassembled, which is a cumbersome operation.

[0003] To address these issues, we provide a stainless steel panel magnetic level gauge. Utility Model Content

[0004] The purpose of this utility model is to provide a stainless steel panel magnetic level gauge, which facilitates vertical installation of the guide tube through the cooperation of the ball, adjusting bolt and metal bellows, and enables quick assembly and disassembly through the cooperation of the operating rod, L-shaped groove and annular plate. This solves the problems of existing technology which makes it inconvenient to install stainless steel panel magnetic level gauges vertically, thus affecting the measurement accuracy of stainless steel panel magnetic level gauges, and the existing technology which requires disassembling and assembling multiple bolts when cleaning the inside of the guide tube, making the operation steps cumbersome.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a stainless steel panel magnetic level gauge, comprising a magnetic level gauge body, which includes a guide tube. Metal corrugated pipes are fixed to the upper and lower sides of the rear peripheral wall of the guide tube. A U-shaped fixing frame is provided on the outer side of the upper end of the guide tube. Adjusting bolts are threadedly connected to the front and rear side walls and the left and right side walls of the fixing frame. A connecting rod is fixed to the rear wall of the lower side of the guide tube. A ball is fixed to the rear end of the connecting rod. A mounting post is provided on the rear side of the ball. A mounting cover threadedly connected to the mounting post is provided on the outer side of the front side of the ball. A quick-release assembly includes a bottom tube fixed to the lower end of the guide tube. An annular plate is provided inside the bottom tube with a clearance fit. L-shaped grooves are formed in a circular array on the peripheral wall of the bottom tube at the location of the annular plate. An operating rod is fixed inside the L-shaped grooves corresponding to the outer peripheral wall of the annular plate.

[0006] The present invention is further provided that a flange is fixedly provided at the rear end of the metal bellows, and mounting holes are provided in a circumferential array along the edge of the flange.

[0007] The present invention is further configured such that one end of the adjusting bolt is located inside the fixed frame and abuts against the guide tube, and a connecting plate is fixedly provided on the rear wall of the fixed frame, and the rear end of the connecting plate is fixedly connected to the corresponding flange.

[0008] The present invention is further provided that a semi-circular mounting groove is provided at the front end of the mounting column corresponding to the position of the sphere, and a mating groove that mates with the sphere is provided on the front wall of the mounting cover.

[0009] The present invention is further configured such that a magnetic float is provided inside the conduit, and a flap box is fixedly provided on the front side of the conduit's peripheral wall.

[0010] The present invention is further configured such that the lower wall of the conduit is provided with a sealing gasket fixed to the annular plate, and the lower wall of the annular plate is fixed with a drain valve.

[0011] The present invention is further provided that the bottom tube corresponding to the inner corner of the L-shaped groove has an inclined surface.

[0012] The present invention is further provided with a stop bar on one side of the operating lever, a limiting sleeve fixed to the bottom tube on the outside of the stop bar, and a boss fixed on the upper end of the stop bar.

[0013] This utility model has the following beneficial effects: This invention utilizes a corrugated metal tube, a sphere, a mounting post, a mounting cover, a fixing frame, and an adjusting bolt. Because the corrugated metal tube can deform slightly, and the sphere can rotate in its original position when adjusting the verticality of the conduit, the conduit can be fixed by placing the end of the adjusting bolt inside the fixing frame against the outer wall of the conduit after it is in a vertical position. Compared to existing technologies, the corrugated metal tube's deformable characteristic allows for adjustment of the conduit's verticality, and the sphere and adjusting bolt work together to fix the conduit in a vertical position, preventing measurement accuracy from being affected by verticality issues.

[0014] This invention uses an L-shaped groove, an annular plate, and an operating rod. The cooperation between the annular plate and the sealing gasket seals the lower end of the conduit. When disassembling or assembling the annular plate, the bottom of the conduit can be opened or sealed by controlling the operating rod to disengage from or enter the L-shaped groove. Compared with the prior art, the operation of opening or sealing the lower end of the conduit is simpler. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Example 1

[0023] Please see Figure 1 , Figure 2 and Figure 3 This is the first embodiment of the present invention, which provides a stainless steel panel magnetic level gauge, including a magnetic level gauge body 1. The magnetic level gauge body 1 includes a conduit 103. The interior of a metal bellows 103a communicates with the interior of the conduit 103. Metal bellows 103a are fixed on both the upper and lower sides of the rear peripheral wall of the conduit 103. The metal bellows 103a has deformable characteristics, which allows the conduit 103 to move relative to the flange 102, achieving the effect of adjusting the conduit 103 to a vertical installation. A U-shaped fixing frame 101 is provided on the outer side of the upper end of the conduit 103. The front and rear side walls of the fixing frame 101 and the fixing frame itself are also included. Adjusting bolts 101a are threaded onto both the left and right side walls of 101. The angle of the upper horizontal direction of the conduit 103 can be adjusted and locked by the cooperation of the four adjusting bolts 101a. A connecting rod 103b is fixedly installed on the rear wall of the lower side of the conduit 103. A ball 107 is fixedly installed at the rear end of the connecting rod 103b. A mounting post 105 is provided on the rear side of the ball 107. The mounting post 105 is fixedly connected to the corresponding flange 102. A mounting cover 106 is provided on the outer front side of the ball 107 and is threadedly connected to the mounting post 105. The ball 107 can rotate in its original position by the cooperation of the mounting post 105 and the mounting cover 106, so that the angle of the conduit 103 can be adjusted. Specifically, a flange 102 is fixed to the rear end of the metal bellows 103a. The flange 102 has mounting holes 102a arranged in a circular array along its edge. By passing bolts through the mounting holes 102a, the flange 102 can be fixed to the flange surface of the tank to be tested, thus fixing the stainless steel panel magnetic level gauge to the tank to be tested. The adjusting bolt 101a is located inside the fixed frame 101, and one end abuts against the guide tube 103. The rear wall of the fixed frame 101 is fixedly provided with a connecting plate 101b. The rear end of the connecting plate 101b is fixedly connected to the corresponding flange 102. The connecting plate 101b makes the fixed frame 101 and the corresponding flange 102 in a relatively fixed state. A semi-circular mounting groove 105a is provided at the front end of the mounting post 105 at the location of the sphere 107, and a mating groove 106a is provided on the front wall of the mounting cover 106 to cooperate with the sphere 107. The above configuration, through the cooperation of the mounting groove 105a and the mating groove 106a, allows the sphere 107 to rotate only in its original position. The conduit 103 is equipped with a magnetic float inside, and a flap box 104 is fixed on the front side of the conduit 103. The magnetic float moves up and down according to the liquid level, which drives the flap inside the flap box 104 to flip. The specific liquid volume can be viewed according to the specific value on the surface of the flap box 104. The magnetic float and the flap box 104 are both existing technologies and will not be described in detail here. The operation process of this embodiment is as follows: During installation, operate the stainless steel panel magnetic level gauge to align the flange 102 with the flange in the tank to be tested, then operate the bolt to pass through the mounting hole 102a and fix the flange 102 to the flange. Next, loosen the adjusting bolt 101a and use a vertical testing tool to test the verticality of the guide tube 103. During the test, rotate the adjusting bolt 101a in the corresponding direction to rotate and drive the upper end of the guide tube 103 to move. In this state, the ball 107 rotates in the original position until the upper end of the guide tube 103 is in a vertical state. Then tighten the adjusting bolt 101a to fix the guide tube 103. Example 2

[0024] Please see Figure 1 , Figure 4 and Figure 5 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but differs from the first embodiment in that: the quick-release component 2 includes a bottom tube 201 fixed to the lower end of the conduit 103. An annular plate 202 is provided inside the bottom tube 201 with a gap fit. When the operating rod 202b is located in the L-shaped groove 201a and the lower end of the conduit 103 is locked, the annular plate 202 squeezes the sealing gasket 202c so that the sealing gasket 202c is tightly fitted to the lower end of the bottom tube 201 to seal the lower end of the bottom tube 201 to avoid leakage. At the location of the annular plate 202, the circumferential wall of the bottom tube 201 is provided with an L-shaped groove 201a in a circular array. The lower end of the bottom tube 201 can be opened and sealed by the operating rod 202b disengaging from or entering the L-shaped groove 201a. The operating rod 202b is fixed inside the L-shaped groove 201a corresponding to the outer circumferential wall of the annular plate 202 to facilitate the movement of the annular plate 202. Specifically, the lower wall of the conduit 103 is provided with a sealing gasket 202c fixed to the annular plate 202. The sealing gasket 202c is annular and is used to seal between the annular plate 202 and the bottom pipe 201. The lower wall of the annular plate 202 is fixed with a drain valve 202a, which is used to discharge the sediment or impurities inside the conduit 103. An inclined surface 201b is provided on the bottom tube 201 corresponding to the inner corner of the L-shaped groove 201a. When the annular plate 202 is installed, the operating rod 202b is rotated after entering the L-shaped groove 201a. Under the action of the inclined surface 201b, the operating rod 202b is easily rotated. A stop bar 203 is provided on one side of the operating lever 202b. A limiting sleeve 201c fixed to the bottom tube 201 is provided on the outside of the stop bar 203. A boss 203a is fixed on the upper end of the stop bar 203. The diameter of the boss 203a is larger than the diameter of the stop bar 203. This prevents the stop bar 203 from moving downward and disengaging from the limiting sleeve 201c after being inserted into it. The stop bar 203 blocks the operating lever 202b, preventing the lower end of the guide tube 103 from accidentally opening due to the operation lever 202b rotating and disengaging from the L-shaped groove 201a caused by external force accidentally touching the operating lever 202b. The operation process in this embodiment is as follows: By opening the drain valve 202a, the sediment or impurities inside the conduit 103 can be discharged. With the lower end of the conduit 103 in a sealed state, the stop rod 203 is moved upwards by operating the boss 203a. Then, the operating rod 202b is controlled to move horizontally along the L-shaped groove 201a to its vertical opening, and then moves downwards, disengaging the operating rod 202b from the L-shaped groove 201a, thus opening the lower end of the conduit 103. The operating tool can then clean the inside of the conduit 103. After cleaning, the impurities on the lower wall of the conduit 103 and the upper wall of the sealing gasket 202c are wiped dry. The control lever 202b is used to insert the sealing gasket 202c into the bottom tube 201. After the sealing gasket 202c contacts the lower wall of the conduit 103, the control lever 202b is rotated to the right corner of the upper side of the L-shaped groove 201a. At this time, the annular plate 202 applies force to the sealing gasket 202c, and the sealing gasket 202c applies pressure to the lower wall of the conduit 103 to prevent leakage between the conduit 103 and the annular plate 202. Then, the boss 203a is operated to insert the stop rod 203 into the limiting sleeve 201c to achieve the limiting effect of the control lever 202b, so as to prevent the control lever 202b from rotating accidentally.
