Description

Technical Field

[0001] The utility model belongs to the technical field of liquid level gauges, in particular to a high-voltage magnetic flap liquid level gauge. Background Art

[0002] The magnetic flap level gauge is an instrument used to measure the liquid level of various towers, tanks, troughs, spherical containers and boilers. It is developed based on the buoyancy principle and magnetic coupling. It is mainly composed of the main body, local indicator, remote transmitter and upper and lower limit alarms. The magnetic flap level gauge is an instrument used to measure the liquid level of various towers, tanks, troughs, spherical containers and boilers. When the liquid level in the measured container rises or falls, the magnetic float in the main tube of the level gauge also rises or falls. The permanent magnet in the float is transmitted to the magnetic flip column indicator through magnetic coupling, driving the red and white flip columns to flip 180°. When the liquid level rises, the flip column changes from white to red, and when the liquid level drops, the flip column changes from red to white. The red and white junction of the indicator is the actual height of the liquid level inside the container, but it still has the following disadvantages in actual use:

[0003] 1. During the use of the magnetic flap level gauge, it is directly installed on the outside of the container being measured. When the air pressure in the container increases, the gas generated by the evaporation of the liquid is discharged through the pressure relief valve and thrown out directly, which will cause the total amount of liquid contained in the container to decrease, resulting in a large loss of container storage;

[0004] 2. During the use of the magnetic flap level gauge, the position of the indicator column is changed directly by the floating of the magnetic float. However, during the operation of the level gauge, the actual liquid storage is different, and different liquids have different densities, which may easily cause the indication accuracy of the level gauge to be insufficient during the operation. Utility Model Content

[0005] The purpose of the utility model is to provide a high-pressure magnetic flap liquid level gauge, which solves the problems that the magnetic flap liquid level gauge may cause a large loss of liquid stored in the measured container during use and the indication accuracy of the liquid level gauge is not high enough by arranging a cylinder, a nut, a closing disk and a fixing tube.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model discloses a high-pressure magnetic flap liquid level gauge, comprising a cylinder, a nut, a closing disk and a fixed tube, wherein a closing disk is arranged at the bottom end of the cylinder, a nut is arranged in the cylinder, the top end of the nut is open, an upper part of an inner wall of the nut is threadedly connected with an externally threaded cylinder, a magnetic suction sheet is fixed in the externally threaded cylinder, the top end of the cylinder is closed, the top end of the cylinder is fixedly connected with a fixing tube, the top end of the fixing tube is fixedly connected with a high-strength balloon, the middle part of the peripheral side of the fixing tube is fixedly connected with a bypass tube, and one end of the bypass tube away from the fixing tube is fixedly connected with a one-way pressure valve. When working, a communicating vessel is formed between the cylinder and a container to be measured, and the liquid level therein is assumed to be the same as the liquid level height in the container to be measured. When working through the nut, the counterweight disk is accommodated therein, the bottom end of the cylinder is closed by the closing disk, and the fixing tube is connected with the high-strength balloon and the bypass tube to prevent excessive pressure in the cylinder.

[0008] Furthermore, a mounting ring is fixed to the lower part of the peripheral side of the cylinder, and mounting bolts are inserted and connected in a circular array in the mounting ring and the closing disk, and the peripheral side of the mounting bolts at the bottom end of the closing disk is threaded with nuts. When the cylinder is working, the mounting ring and the closing disk are installed together with the cooperation of the mounting bolts and nuts.

[0009] Furthermore, the cylinder body has two corresponding upper and lower connecting tubes fixedly connected to its circumference, and mounting plates are fixed to the edges of the two connecting tubes away from the cylinder body. When the cylinder body is working, the connecting tube is connected to the container to be measured through the mounting plates on the connecting tubes, so that a communicating vessel is formed between the cylinder body and the container to be measured.

[0010] Furthermore, a flap indicator scale is fixed at a position symmetrical to the connecting pipe on the circumference of the cylinder, and connecting blocks are fixed at both ends of the flap indicator scale. The connecting blocks are fixed on the circumference of the cylinder, and the liquid level in the cylinder is determined by the color change on the flap indicator scale. The connection strength between the flap indicator scale and the cylinder is increased by the connecting block.

[0011] Furthermore, a counterweight plate is provided in the lower inner part of the nut, and a floating block is fixed to the top of the external threaded tube and the magnetic sheet. The nut adjusts the position of the magnetic sheet in the measured container by selecting a suitable weight of the counterweight plate before installation.

[0012] Furthermore, a connecting hole is opened through the center of the closed disk, a drain pipe is fixed at the center of the bottom end of the closed disk, the drain pipe is connected to the connecting hole, a drain valve is fixed in the middle of the peripheral side of the drain pipe, and the dirt on the closed disk is discharged through the drain pipe after the drain valve is opened.

[0013] The utility model has the following beneficial effects:

[0014] 1. The utility model solves the problem that the magnetic flap liquid level gauge may cause a large loss of liquid stored in the measured container during use by arranging a cylinder and a fixed tube. When the air pressure in the liquid and the measured container increases, the pressure is transmitted to the cylinder, transported to the fixed tube through the cylinder, and transported to the high-strength balloon through the fixed tube, and temporarily contained by the high-strength balloon. When the pressure in the cylinder drops, the gas in the high-strength balloon flows back into the cylinder to reduce waste. When the gas pressure is too high, the gas is transported to the one-way pressure valve through the bypass pipe, and the one-way pressure valve is opened to discharge the gas to prevent the cylinder from being damaged by excessive pressure. During the use of the magnetic flap liquid level gauge, the volume that can accommodate gas is increased, the situation that pressure relief is required due to excessive pressure is reduced, and the loss of liquid stored in the measured container is smaller.

[0015] 2. The utility model solves the problem of insufficient indication accuracy of the magnetic flap level gauge by setting a cylinder, a nut and a closing disk. Before installing the closing disk at the bottom of the cylinder, first select a suitable nut, put a counterweight disk of appropriate weight into the nut, and then align the nut with the external threaded cylinder at the bottom of the floating block, tighten the nut and the external threaded cylinder, and then put it into the cylinder. The bottom end of the nut is closed and faces the closing disk. After the installation is completed, it can work, so that when working, the top of the magnetic suction sheet is set at the junction of the liquid surface, accurately displaying the liquid level in the container on the flap indicator scale, and the liquid level display accuracy is higher.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment 1

[0027] See also Figure 1-6 The utility model is a high-pressure magnetic flap level gauge, comprising a cylinder 1, a nut 2, a closing disk 3 and a fixing tube 4. A closing disk 3 is arranged at the bottom end of the cylinder 1. When the cylinder 1 is working, the nut 2 is accommodated therein, and a communicating vessel is formed between the cylinder 1 and the container to be measured pressure, so that the liquid level in the cylinder 1 is flush with the liquid level in the container to be measured. A nut 2 is arranged in the cylinder 1, and a counterweight disk 204 is accommodated therein through the nut 2. The top end of the nut 2 is arranged with an opening, so that when working, an externally threaded cylinder 201 is threadedly connected therein, and the upper part of the inner wall of the nut 2 is threadedly connected with the externally threaded cylinder 201. When working through the externally threaded cylinder 201, a magnetic suction sheet 202 is fixed therein, and the magnetic suction sheet 202 is arranged and accommodated in the nut 2, and a magnetic suction sheet 202 is fixed in the externally threaded cylinder 201. Through the magnetic suction sheet 202 The magnetic force affects the indication on the flap indicator scale 102 to determine the liquid level in the cylinder 1 and display the liquid level in the container forming a communicating vessel with the cylinder 1. The top of the cylinder 1 is closed and fixedly connected to a fixed tube 4 at the top of the cylinder 1. A high-strength balloon 403 is fixedly connected to the top of the fixed tube 4. A bypass tube 401 is fixedly connected to the middle of the peripheral side of the fixed tube 4. An end of the bypass tube 401 away from the fixed tube 4 is fixedly connected to a one-way pressure valve 402. When the air pressure in the cylinder 1 increases, the pressure is transmitted to the high-strength balloon 403 through the fixed tube 4. When the pressure in the cylinder 1 drops, the air entering the high-strength balloon 403 is refluxed through the fixed tube 4 and transported to the cylinder 1. When the pressure is too high, the one-way pressure valve 402 on the bypass tube 401 opens, and the high-pressure air in the cylinder 1 is discharged through the opening of the one-way pressure valve 402.

[0028] Specifically, a mounting ring 103 is fixed to the lower part of the peripheral side of the cylinder body 1, and mounting bolts are inserted and connected in a circular array in the mounting ring 103 and the closing disk 3, and the peripheral side of the mounting bolts at the bottom end of the closing disk 3 is threaded with nuts. When installing the closing disk 3, the top end of the closing disk 3 is aligned and contacted with the bottom end of the mounting ring 103, and the mounting bolts are inserted into the mounting ring 103, inserted into the closing disk 3, and extended out of the closing disk 3, and then the nuts are screwed onto the mounting bolts. After tightening, the cylinder body 1 and the closing disk 3 are installed.

[0029] Furthermore, two upper and lower corresponding connecting tubes 104 are fixedly connected to the periphery of the cylinder 1, and mounting plates 105 are fixed on the periphery of the two connecting tubes 104 away from the edges of the cylinder 1. When the cylinder 1 is working, the mounting plate 105 is connected thereto through the connecting tube 104. When the mounting plate 105 is working, the connecting tube 104 is connected to the container whose liquid level needs to be detected, so that a communicating vessel is formed between the cylinder 1 and the container whose liquid level needs to be detected.

[0030] Furthermore, a flap indicator scale 102 is fixed on the circumferential side of the cylinder 1 at a position symmetrical to the connecting pipe 104, and connecting blocks 101 are fixed at both ends of the flap indicator scale 102. The connecting block 101 is fixed on the circumferential side of the cylinder 1. When the nut 2 is raised or lowered in the cylinder 1, the indication of the flap indicator scale 102 is changed, and the flap indicator scale 102 increases the connection strength through the connecting block 101.

[0031] The operation process of this embodiment is as follows: when working, first align the mounting disk 105 on the two connecting pipes 104 on the outside of the cylinder 1 with the mounting position of the mounting container, insert the bolts into the mounting disk 105, and then screw them into the corresponding mounting position of the container to complete the installation, so that a connecting vessel is formed between the container of the measured liquid level and the cylinder 1. When the container is filled with liquid, the liquid enters the cylinder 1. When the air pressure in the liquid and the measured container increases, the pressure is transmitted to the cylinder 1, and is transported to the fixed pipe 4 through the cylinder 1, and then transported to the high-strength balloon 403 through the fixed pipe 4, and temporarily contained by the high-strength balloon 403. When the pressure in the cylinder 1 drops, the gas in the high-strength balloon 403 flows back to the cylinder 1 to reduce waste. When the gas pressure is too high, the gas is transported to the one-way pressure valve 402 through the bypass pipe 401, and the one-way pressure valve 402 opens to discharge the gas to prevent the cylinder 1 from being damaged by excessive pressure. Specific embodiment 2

[0033] See also Figure 1 , 2, 3, 4, on the basis of the specific embodiment 1, a counterweight plate 204 is provided in the lower inner part of the nut 2, and a floating block 203 is fixed to the top of the external threaded tube 201 and the magnetic sheet 202. The nut 2 is weighted by the counterweight plate 204, and the floating block 203 floats, so that the position of the nut 2 in the cylinder 1 changes with the change of the liquid level.

[0034] Specifically, a connecting hole 301 is opened through the center of the closed disk 3, a drain pipe 302 is fixed at the center of the bottom end of the closed disk 3, the drain pipe 302 is connected to the connecting hole 301, and a drain valve 303 is fixed in the middle of the peripheral side of the drain pipe 302. After long-term use, impurities and dirt are accumulated on the top of the closed disk 3, and the drain valve 303 is directly opened. At this time, the dirt in the cylinder 1 at the top of the closed disk 3 climbs out through the drain pipe 302. The drain valve 303 is closed until the outflowing liquid is the liquid for normal use.

[0035] The operation process of this embodiment is as follows: when working, before installing the closing disk 3 at the bottom end of the cylinder 1, first select a suitable nut 2, put the counterweight disk 204 of appropriate weight into the nut 2, and then align the nut 2 with the external threaded tube 201 at the bottom end of the floating block 203, tighten the nut 2 and the external threaded tube 201, and then put it into the cylinder 1, with the bottom end of the nut 2 in a closed setting facing the closing disk 3. After the installation is completed, it can work, so that when working, the top end of the magnetic suction sheet 202 is set at the intersection position of the liquid surface, and the liquid level in the container is accurately displayed on the flip plate indicator scale 102.
