Description

Technical Field

[0001] The utility model relates to the technical field of magnetic fluid valves, in particular to a magnetic fluid valve which is easy to maintain. Background Art

[0002] A magnetic fluid valve is a valve device implemented using magnetic fluid technology, primarily used to control the flow of fluids. The core component of a magnetic fluid valve is magnetic fluid, a special magnetic fluid with both magnetic and fluid properties. A magnetic fluid valve typically consists of a valve body, a valve housing, a permanent magnet, a solenoid coil, and the magnetic fluid. When the solenoid coil is de-energized, the magnetic fluid is distributed along the inner wall of the valve body near the permanent magnet, allowing conduction between the two ends of the valve body. When the solenoid coil is energized, the magnetic fluid accumulates within the valve body between the permanent magnet and the solenoid coil, closing the valve body.

[0003] When using a magnetic fluid valve, the valve interface needs to be connected to the pipeline interface so that it can be used. However, when some magnetic fluid valves are damaged and need maintenance, it is inconvenient to block the connection for maintenance; therefore, it does not meet the existing needs. In this regard, we propose a magnetic fluid valve that is easy to maintain. Utility Model Content

[0004] The purpose of the utility model is to provide a magnetic fluid valve that is easy to maintain, so as to solve the problem that the magnetic fluid valve proposed in the above background technology needs to be connected to the interface of the valve and the interface of the pipeline when it is used, but when some magnetic fluid valves are damaged and need maintenance, it is inconvenient to block their connections for maintenance.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a magnetic fluid valve that is easy to maintain, comprising a valve body, both sides of the upper end of the valve body are fixedly connected with a connecting seat that is connected to the interior of the valve body, the upper ends of the connecting seats on both sides are threadedly connected with a threaded rod that extends into the interior of the connecting seat, one end of the threaded rod located inside the connecting seat is rotatably connected to a partition via a rotating shaft, and the partition movably extends to the interior of the valve body, grooves are provided on both sides below the partition and at the bottom end of the valve body, and sliding grooves are provided on both sides of the grooves near the bottom end, and a slide is slidably connected between the slides on both sides, the upper end of the slide is fixedly connected with a block, and the bottom end of the partition is movably contacted with the upper end of the block.

[0006] Preferably, the front and rear outer surfaces of the partition are in sealing contact with the inner wall of the valve body via a sealing gasket.

[0007] Preferably, a spring is fixedly connected between the bottom end of the slide plate and the bottom end of the inside of the groove.

[0008] Preferably, sealing rubber pads are fixedly connected above the two slide grooves and on the inner walls of the grooves, and the sealing rubber pads are in close contact with the left and right sides of the block.

[0009] Preferably, the width of the partition is consistent with the width of the block, and the left and right sides of the partition are in close contact with the sealing gasket when the partition moves downward.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] The utility model rotates the threaded rods on both sides so that the threaded rods are threadedly rotated on the top of the connecting seat, thereby pushing the partition toward the inside of the valve body. When the bottom end of the partition contacts the upper end of the block, the slide plate at the bottom end of the block is pushed to slide along the slide groove and squeeze the spring to compress, so that the partition is inserted into the inside of the groove, and the width of the partition is consistent with that of the block. When the partition is inserted into the inside of the groove, the sealing gaskets on both sides of the inner wall of the groove are in sealing contact with both sides of the partition, thereby blocking the connection between the valve and the pipeline, making it convenient to maintain the magnetic fluid valve.

A spring 7 is fixedly connected between the bottom end of the slide plate 6 and the bottom end of the inside of the groove 101. By rotating the threaded rods 3 on both sides, the threaded rods 3 are threadedly rotated on the top of the connecting seat 2, thereby pushing the partition 4 toward the inside of the valve body 1. When the bottom end of the partition 4 contacts the upper end of the block 8, the slide plate 6 at the bottom end of the block 8 is pushed to slide along the slide groove 1011 and squeeze the spring 7 to compress, so that the partition 4 is inserted into the inside of the groove 101.
