Description

Technical Field

[0001] The utility model belongs to the technical field of electromagnetic flowmeters, and particularly relates to an insertion type electromagnetic flowmeter. Background Technique

[0002] The insertion type electromagnetic flowmeter is a special type of electromagnetic flowmeter, mainly used for measuring the volume flow of conductive liquids in large-diameter pipelines. It realizes flow measurement by inserting a sensor into the pipeline without cutting off the pipeline or stopping the fluid flow.

[0003] At present, the existing insertion type electromagnetic flowmeters on the market mostly have the following deficiencies during use: long-term use of the insertion type electromagnetic flowmeter will cause the electrodes to become dirty or worn, etc., thus affecting the measurement accuracy. Therefore, in order to ensure the accuracy of the flowmeter measurement, regular maintenance is required. Most of the existing insertion type electromagnetic flowmeters are fixed by multiple screws. When performing maintenance, personnel need to disassemble multiple screws, which is very cumbersome, time-consuming and laborious, greatly reducing the work efficiency. If the screwdriver is lost, it cannot be disassembled. At the same time, when the screws rust, they will slip and the rusty screws cannot be removed. In view of this, we propose an insertion type electromagnetic flowmeter. Content of the Utility Model

[0004] The purpose of the utility model is to provide an insertion type electromagnetic flowmeter to solve the problems raised in the above background technique.

[0005] In view of this, the utility model provides an insertion type electromagnetic flowmeter, including an electromagnetic flowmeter body, a pipeline and a vertical pipe. The vertical pipe is fixedly installed on the top of the pipeline, and the electromagnetic flowmeter body is located above the pipeline. The adjustment measurement insertion rod and the sensor on the electromagnetic flowmeter body both penetrate through the vertical pipe and extend into the pipeline. It further includes:

[0006] A connecting pipe, the connecting pipe is fixedly installed on the adjustment measurement insertion rod of the electromagnetic flowmeter body, and the connecting pipe is sleeved on the vertical pipe;

[0007] A ring buckle, the ring buckle is sleeved on the connecting pipe and the vertical pipe, and an annular groove is opened in the ring buckle. A first fixing ring fixed to the connecting pipe is clamped and installed in the annular groove, and a second fixing ring fixed to the vertical pipe is also clamped and installed in the annular groove;

[0008] Two fixing blocks, the two fixing blocks are symmetrically and fixedly installed on the ring buckle. A rubber pad is fixedly installed on one of the fixing blocks. A pressing block is rotatably installed on one side of the rubber pad. A T-shaped cylinder is rotatably installed in the pressing block, and one end of the T-shaped cylinder penetrates through the pressing block, the rubber pad and one side of the two fixing blocks and is threadedly installed with a nut. A handle is fixedly installed on the side of the pressing block close to the ring buckle.

[0009] In the above technical solution, further, a threaded groove is provided in the connecting pipe, and the upper end of the vertical pipe is located in the threaded groove. The vertical pipe is threadedly connected to the threaded groove, and a sealing gasket is fixedly installed at the top of the vertical pipe and at the top of the threaded groove.

[0010] In this technical solution, it is ensured that the connecting pipe is properly threadedly connected to the vertical pipe through the threaded groove, and it is ensured that the vertical pipe can squeeze the sealing gasket, so that the sealing gasket can be in close contact with the vertical pipe and the connecting pipe, improving the sealing performance between the connecting pipe and the vertical pipe.

[0011] In the above technical solution, further, the pipeline, the vertical pipe and the second fixing ring are of an integrally formed structure, and the connecting pipe and the first fixing ring are of an integrally formed structure.

[0012] In this technical solution, the structural stability of the vertical pipe and the second fixing ring is ensured, and the structural stability of the connecting pipe and the first fixing ring is guaranteed.

[0013] In the above technical solution, further, the two fixing blocks and the ring buckle are of an integrally formed structure. The height of the annular groove is equal to the sum of the heights of the second fixing ring and the first fixing ring, and the thickness of the annular groove is equal to the thicknesses of the first fixing ring and the second fixing ring.

[0014] In this technical solution, the structural stability of the two fixing blocks and the ring buckle is ensured. When the second fixing ring contacts the first fixing ring, the annular groove can be sleeved on the second fixing ring and the first fixing ring at the same time, and it is ensured that the annular groove can just clamp the second fixing ring and the first fixing ring, so that the second fixing ring and the first fixing ring will not fall off in the annular groove.

[0015] In the above technical solution, further, it further includes:

[0016] A non-slip rubber, which is fixedly installed on the nut.

[0017] In this technical solution, the friction when turning the nut is increased, and it is ensured that the nut can be turned by hand.

[0018] In the above technical solution, further, the T-shaped cylinder has a T-shaped structure. One end of the T-shaped cylinder is slidably connected to the fixing block and the rubber pad, and the center of the T-shaped cylinder in the vertical direction deviates from the center position on the pressing block.

[0019] In this technical solution, it is ensured that one end of the T-shaped cylinder can slide normally in the fixing block and the rubber pad, and when the pressing block rotates on the T-shaped cylinder, it will squeeze the rubber pad and cause the T-shaped cylinder to move a certain distance in the direction of the handle.

[0020] In the above technical solution, further, the pressing block and the handle are of an integrally formed structure, and the rubber pad is fixedly installed on the fixing block.

[0021] In this technical solution, the structures of the pressing block and the handle are ensured to be stable, and the structures of the rubber pad and the fixing block are ensured to be stable.

[0022] The beneficial effects of the present utility model are as follows:

[0023] For this plug-in electromagnetic flowmeter, through the settings of the connecting pipe, the ring buckle, the gasket, the nut, the rubber pad, the T-shaped cylinder, the pressing block, the handle, the annular groove, the fixing block, the first fixing ring, and the second fixing ring, it is ensured that the entire device does not need to disassemble multiple screws during disassembly. The entire disassembly process saves time and effort, greatly improving work efficiency. Personnel can also disassemble the device without a screwdriver, and at the same time, it also avoids the occurrence of slipping when the screws rust. Description of the Drawings

[0041] Please refer to Figures 1-9 as shown in the figure, this embodiment provides an insertion type electromagnetic flowmeter, which includes an electromagnetic flowmeter body 1, a pipeline 3 and a vertical pipe 6. The vertical pipe 6 is fixedly installed at the top of the pipeline 3, and the electromagnetic flowmeter body 1 is located above the pipeline 3.

A first fixing ring 51 fixed to the connecting pipe 5 is snap-fitted in the annular groove 18, and a second fixing ring 61 fixed to the vertical pipe 6 is also snap-fitted in the annular groove 18;

[0044] Two fixing blocks 19, the two fixing blocks 19 are symmetrically and fixedly installed on the loop buckle 7. A rubber pad 11 is fixedly installed on one of the fixing blocks 19. A pressing block 13 is rotatably installed on one side of the rubber pad 11. A T-shaped cylinder 12 is rotatably installed in the pressing block 13, and one end of the T-shaped cylinder 12 penetrates through the pressing block 13, the rubber pad 11 and one side of the two fixing blocks 19 and is threadedly installed with a nut 9. A handle 14 is fixedly installed on the side of the pressing block 13 close to the loop buckle 7.

[0045] Wherein, under the action of the thread, rotate the connecting pipe 5 and screw the connecting pipe 5 onto the vertical pipe 6 until the bottom of the first fixing ring 51 contacts the top of the second fixing ring 61;

[0046] Subsequently, unscrew the nut 9 at one end of the T-shaped cylinder 12 by hand, and then remove the T-shaped cylinder 12 from the two fixing blocks 19 and the rubber pad 11. Subsequently, pull the two fixing blocks 19 outwards with both hands so that the electromagnetic flowmeter body 1 can pass between the two fixing blocks 19, and put the loop buckle 7 on the fixing ring one 51 and the fixing ring two 61. Then, pass one end of the T-shaped cylinder 12 through the two fixing blocks 19 and the rubber pad 11, and under the action of the thread, screw the nut 9 onto one end of the T-shaped cylinder 12 by hand, so that the two fixing blocks 19 approach each other and the loop buckle 7 fits on the surfaces of the connecting pipe 5 and the vertical pipe 6.

Subsequently, pull the two fixing blocks 19 outwards with both hands so that the loop buckle 7 is removed from the fixing ring one 51 and the fixing ring two 61. Then, rotate the connecting pipe 5 counterclockwise until the connecting pipe 5 is completely unscrewed from the vertical pipe 6. At this time, pull the connecting pipe 5 upwards and drive the electromagnetic flowmeter body 1 to be taken out from the vertical pipe 6 and the pipeline 3, and the operator can maintain the taken-out electromagnetic flowmeter body 1.

[0068] Subsequently, unscrew the nut 9 at one end of the T-shaped cylinder 12 by hand, and then remove the T-shaped cylinder 12 from the two fixed blocks 19 and the rubber pad 11. Subsequently, pull the two fixed blocks 19 outwards with both hands so that the electromagnetic flowmeter body 1 can pass between the two fixed blocks 19, and put the loop buckle 7 on the first fixing ring 51 and the second fixing ring 61.

[0069] During disassembly, rotate the handle 14 in the reverse direction by 90 degrees and drive the pressing block 13 to rotate. At the same time, the rubber pad 11 will lose the extrusion of the pressing block 13, so that the two fixed blocks 19 will drive the two fixed blocks 19 to move away from each other under the action of the self-toughness of the loop buckle 7. One of the fixed blocks 19 drives the rubber pad 11 to gently squeeze on the other end of the T-shaped cylinder 12, and the other fixed block 19 gently squeezes the nut 9. At this time, the operator can rotate the nut 9 by hand until the nut 9 is removed from one end of the T-shaped cylinder 12, and then remove the T-shaped cylinder 12 from the two fixed blocks 19 and the rubber pad 11. Subsequently, pull the two fixed blocks 19 outwards with both hands so that the loop buckle 7 is removed from the first fixing ring 51 and the second fixing ring 61. Subsequently, rotate the connecting pipe 5 in the reverse direction until the connecting pipe 5 is completely unscrewed from the vertical pipe 6.
