Electromagnetic pump inlet and outlet port pipeline butt joint structure

Abstract

This utility model relates to the technical field of electromagnetic pump auxiliary connection devices, and more particularly to a connection structure for the inlet and outlet pipes of an electromagnetic pump. This utility model provides such a connection structure for the inlet and outlet pipes of an electromagnetic pump, including an electromagnetic pump body, an inlet port, an outlet port, and a connecting sleeve. The inlet port is fixedly connected to the left side of the electromagnetic pump body, and the outlet port is fixedly connected to the right side of the electromagnetic pump body. Both the inlet and outlet ports are externally connected to the connecting sleeve by bolts. By pushing the delivery pipe towards the channel pipe, aligning the end of the channel pipe with the end of the support sleeve, and ensuring that the channel pipe and the delivery pipe are coaxial, rotating the rotating ring drives the threaded block to move along the channel pipe, gradually reducing the distance between the channel pipe and the delivery pipe until the connection is completed and locked.

Description

Technical Field

[0001] This utility model relates to the technical field of electromagnetic pump auxiliary connection device, and in particular to a connection structure for the oil inlet and outlet pipes of an electromagnetic pump. Background Technology

[0002] An electromagnetic pump is a type of pump that uses electromagnetic force to drive fluid flow. Its working principle is based on electromagnetic induction and the Lorentz force: when a conductive fluid carries an electric current in a magnetic field, it experiences a Lorentz force perpendicular to both the magnetic field and the current direction, thus propelling the fluid along the direction of the force to achieve the purpose of transportation. Electromagnetic pumps are characterized by no mechanical wear, excellent sealing, and suitability for transporting highly corrosive fluids and fluids requiring high purity. They are widely used in metallurgy, chemical industry, nuclear industry, and other fields.

[0003] As a core component of fluid transport systems, the reliability of the connection between the electromagnetic pump's inlet / outlet and the oil pipeline is crucial, directly affecting the sealing performance and operational stability of the entire system. However, existing connection structures have significant shortcomings: First, the sealing design often relies on a single O-ring, which, during long-term operation, can lead to aging and plastic deformation of the sealing material due to oil temperature fluctuations and equipment vibrations, thus increasing the risk of leakage. Second, the connection methods have drawbacks. Whether it's a threaded connection requiring the wrapping of PTFE tape or the application of sealant, or a flange connection requiring the disassembly and assembly of multiple bolts, both suffer from cumbersome operation and low maintenance efficiency, increasing system downtime and maintenance costs.

[0004] Therefore, it is necessary to design a connection structure for the inlet and outlet pipes of the electromagnetic pump. Utility Model Content

[0005] In order to overcome the shortcomings of existing electromagnetic pump oil port docking structures, such as poor sealing reliability, easy oil leakage, cumbersome connection method, low maintenance efficiency and high cost, this utility model provides an electromagnetic pump inlet and outlet pipe docking structure.

[0006] The technical implementation scheme of this utility model is as follows: an inlet and outlet pipe docking structure for an electromagnetic pump, comprising an electromagnetic pump body, an inlet port, an outlet port, a connecting sleeve, a channel pipe, a delivery pipe, a support sleeve, a threaded block, and a rotating ring. The inlet port is fixedly connected to the left side of the electromagnetic pump body, and the outlet port is fixedly connected to the right side of the electromagnetic pump body. Both the inlet port and the outlet port are externally connected to the connecting sleeve by bolts. The channel pipe is fixedly connected to the outside of the connecting sleeve. The channel pipe is threadedly connected to the outside of the channel pipe. The rotating ring is fixedly connected to the outside of the threaded block. There are two delivery pipes. The support sleeve is fixedly connected to the outside of each delivery pipe. The threaded block is threadedly connected to the support sleeve on the same side.

[0007] As a preferred technical solution of this utility model, it also includes a sealing ring, and the sealing ring is fixedly connected to the side of the channel pipe and the conveying pipe that are close to each other on the same side.

[0008] As a preferred technical solution of this utility model, it also includes a locking block, a return spring, and a lifting block. The locking block is slidably connected inside the support sleeve, and the lifting block is fixedly connected to the top of the locking block. The locking blocks are in contact with the threaded block on the same side. Multiple return springs are connected between the support sleeve and the locking block.

[0009] As a preferred technical solution of this utility model, it also includes a support frame, a torsion spring and a rotating disk. The support frame is fixedly connected to the outside of each conveying block, and the rotating disk is rotatably connected to the outside of each conveying block. The rotating disk is in contact with the corresponding lifting block, and the torsion spring is connected between the support frame and the rotating disk.

[0010] As a preferred technical solution of this utility model, grooves are provided on the threaded blocks.

[0011] As a preferred technical solution of this utility model, the rotating disk is provided with protrusions.

[0012] Beneficial effects: 1. By pushing the delivery pipe toward the channel pipe, aligning the end of the channel pipe with the end of the support sleeve, and ensuring that the channel pipe and the delivery pipe are coaxial, the rotating ring is rotated to drive the threaded block to move along the channel pipe, so that the distance between the channel pipe and the delivery pipe gradually decreases until the docking and locking are completed. This solves the problems of poor sealing reliability, easy oil leakage, cumbersome connection method, low maintenance efficiency and high cost of the existing electromagnetic pump oil port docking structure.

[0013] 2. This utility model, by setting a locking block, a return spring, and a lifting block, forms a stable mechanical interlock by automatically locking the locking block into the groove of the threaded block under the action of the return spring. This effectively resists the impact of vibration and pressure fluctuations, prevents the threaded block from accidentally loosening or rotating during operation, and ensures the long-term stability of the connection in high-pressure and vibration environments.

[0014] 3. This utility model, by setting a torsion spring and a rotating disk, allows the locking block to be lifted and the interlock to be released by turning the rotating disk, thereby easily loosening the threaded block. The torsion spring then resets it, effectively avoiding the problems of rusting, jamming, or the need for violent disassembly that are common in traditional connection methods. This extends the overall service life and reduces the difficulty of maintenance and subsequent replacement costs. Attached Figure Description

Detailed Implementation

[0021] Example: A connection structure for the inlet and outlet pipes of an electromagnetic pump, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the system includes an electromagnetic pump body 1, an oil inlet port 2, an oil outlet port 3, a connecting sleeve 4, a channel pipe 5, a sealing ring 6, a delivery pipe 7, a support sleeve 8, a threaded block 9, and a rotating ring 10. The oil inlet port 2 is welded to the left side of the electromagnetic pump body 1, and the oil outlet port 3 is welded to the right side of the electromagnetic pump body 1. Both the oil inlet port 2 and the oil outlet port 3 are connected to the connecting sleeve 4 by bolts. The channel pipe 5 is welded to the outside of the connecting sleeve 4. The channel pipe 5 is threadedly connected to the outside of the channel pipe 5. The threaded block 9 is provided with a groove. The rotating ring 10 is welded to the outside of the threaded block 9. There are two delivery pipes 7. The channel pipe 5 and the delivery pipe 7 on the same side are bonded with a sealing ring 6 on the side that are close to each other. The support sleeve 8 is welded to the outside of the delivery pipe 7. The threaded block 9 is threadedly connected to the support sleeve 8 on the same side.

[0022] like Figure 2 , Figure 4 and Figure 5 As shown, it also includes a locking block 11, a return spring 12, and a lifting block 13. The locking block 11 is slidably connected inside the support sleeve 8. The lifting block 13 is welded to the top of the locking block 11. The locking block 11 is in contact with the threaded block 9 on the same side. Two return springs 12 are connected between the support sleeve 8 and the locking block 11.

[0023] like Figure 1 , Figure 2 and Figure 5As shown, it also includes a support frame 14, a torsion spring 15 and a rotating disk 16. The support frame 14 is welded to the outside of each conveying block, and the rotating disk 16 is rotatably connected to the outside of each conveying block. The rotating disk 16 is provided with a protrusion, and the rotating disk 16 is in contact with the corresponding lifting block 13. The torsion spring 15 is connected between the support frame 14 and the rotating disk 16.

[0024] Initially, the channel pipe 5 and the delivery pipe 7 are not connected. When it is necessary to connect the oil inlet port 2 and the oil outlet port 3 of the electromagnetic pump, the operator first holds the delivery pipe 7 and slowly pushes it towards the channel pipe 5, aligning the end of the channel pipe 5 with the end of the support sleeve 8, ensuring that the channel pipe 5 and the delivery pipe 7 are coaxial. Then, the rotating ring 10 is rotated, which drives the threaded block 9 to rotate synchronously, making a linear movement along the channel pipe 5 away from the electromagnetic pump body 1. As the threaded block 9 moves linearly, its inner wall slope gradually contacts the bottom slope of the locking block 11. 9 continues to rotate and advance, thereby pushing the locking block 11 upward. The return spring 12 is compressed, and at the same time the threaded block 9 rotates, causing the distance between the channel pipe 5 and the delivery pipe 7 to gradually decrease. The sealing rings 6 at the ends of the two gradually come into contact and are initially squeezed, causing them to undergo elastic deformation and perfectly fill all the micro gaps, thus forming a reliable high-pressure sealing barrier. When the locking block 11 is engaged in the groove on the threaded block 9, the locking block 11 is quickly ejected downward under the action of the return spring 12 and engaged in the groove of the threaded block 9. At this time, a clear "click" sound will be emitted, thus completing the docking and locking process.

[0025] When disassembly, maintenance, or pipe replacement is required, the operator sequentially rotates the rotating disk 16. The rotating disk 16 rotates against the force of the torsion spring 15 until the protrusion on it contacts the locking block 11 and stops rotating. The protrusion pushes the locking block 11 to slide upward, and the return spring 12 is compressed again, allowing the rotating ring 10 to rotate in the opposite direction. The threaded block 9 rotates accordingly and moves along the channel pipe 5 towards the side closer to the electromagnetic pump body 1 to reset. During the reset process of the threaded block 9, the distance between the channel pipe 5 and the delivery pipe 7 gradually increases, and the two squeezed sealing rings 6 lose their squeezing force and gradually spring back to their naturally extended state. Then, the rotating disk 16 is released, the torsion spring 15 releases its elastic potential energy and returns to its original state, the rotating disk 16 returns to its original position, and the locking block 11, without the thrust of the rotating disk 16, returns to its original position under the action of the return spring 12. The return spring 12 returns to its original state, and finally, the delivery pipe 7 is pulled away from the electromagnetic pump body 1, so that the channel pipe 5 and the delivery pipe 7 are completely separated, returning to the initial non-connected state. The disassembly is complete. The above operation can be repeated when disassembly and assembly are required again.
