[0020] The names of parts referred to by the respective numeral designations in the drawings are as follows:

[0021] 100, pulling conduit; 200, sleeve; 300, water outlet conduit. DETAILED DESCRIPTION

[0022] In order to further understand the content of the utility model, the utility model is described in detail in combination with the drawings and embodiments. It should be understood that the embodiments are only used to explain the utility model and are not limited.

[0023] Embodiment 1

[0024] As shown in the drawings, Figure 1 A water-cooled silicate magnetic bar impedance device system is provided in the embodiment, which comprises a pulling conduit 100, a sleeve 200 and a water outlet conduit 300, wherein the pulling conduit 100 is connected with the first end of the sleeve 200, the water outlet conduit 300 is connected with the second end of the sleeve 200, so that the pulling conduit 100 and the water outlet conduit 300 are both in communication with the sleeve 200, and the pulling conduit 100 can also play a role of pulling the sleeve 200 while being connected with the sleeve 200.

[0025] Further, one end of the drawing pipe 100 is connected with an external water source, so that water can be drawn into the sleeve 200 through the drawing pipe 100. A magnetic rod (not shown in the figure) is placed in the sleeve 200, and after the water is drawn into the sleeve 200 by the drawing pipe 100, the water flows through the sleeve 200 as a cooling liquid and is discharged through the water outlet pipe 300.

[0026] It can be understood that when the water drawn into the sleeve 200 by the drawing pipe 100 flows through the sleeve 200 as a cooling liquid, the cooling liquid will come into contact with the magnetic rod placed in the sleeve 200. Through the direct contact between the cooling liquid and the magnetic rod, the heat on the magnetic rod can be transferred to the cooling liquid, thereby achieving cooling of the magnetic rod to prevent the temperature of the magnetic rod from exceeding its Curie point. After the cooling liquid absorbs part of the heat on the magnetic rod, the cooling liquid can be discharged through the water outlet pipe 300. In this process, the drawing pipe 100 continuously draws water with a lower temperature into the sleeve 200, so that the magnetic rod can be continuously cooled.

[0027] Further, since the magnetic rod is placed inside the sleeve 200, the sleeve 200 can play a certain protective role for the magnetic rod. Specifically, the sleeve 200 can isolate the magnetic rod from the external environment, so that the magnetic rod can be protected from the damage of high-temperature welding and high-temperature welding droplets.

[0028] In some embodiments, a water pump (not shown in the figure) can be provided on the drawing pipe 100. When the temperature of the magnetic rod inside the sleeve 200 is high, the water pump can be started to draw water from an external water source through the drawing pipe 100 and introduce it into the sleeve 200 through the drawing pipe 100, thereby providing water as a cooling liquid for the sleeve 200, so that the magnetic rod can be automatically and continuously cooled.

[0029] In some embodiments, the sleeve 200 is made of silicate material.

[0030] It can be understood that silicate has high hardness and high heat resistance, so that the sleeve 200 made of silicate material also has high hardness and high heat resistance, so that the sleeve 200 can have a more stable structural state and better protect the internal magnetic rod. When high-temperature droplets fall on the sleeve 200, they will not cause much damage to the sleeve 200, thereby avoiding the influence of high-temperature droplets on the magnetic rod. Of course, the sleeve 200 with high-temperature resistance can be stably sleeved on the magnetic rod with high temperature, and the sleeve 200 can be placed in an environment with high temperature.

[0031] In some embodiments, the pulling pipe 100 is made of stainless steel. It can be understood that the pulling pipe 100 is made of high-strength stainless steel, so that the pulling pipe 100 also has high structural strength, thereby making the pulling effect of the pulling pipe 100 on the sleeve pipe 200 more stable.

[0032] Further, the water outlet pipe 300 is also made of stainless steel. It can be understood that stainless steel also has good corrosion resistance and oxidation resistance, thereby making the water outlet pipe 300 also have good corrosion resistance and oxidation resistance. Since the water in the sleeve pipe 200 becomes high temperature after absorbing the heat of the magnetic rod as a cooling liquid, and then the cooling liquid with high temperature is discharged through the water outlet pipe 300, the water outlet pipe 300 is affected by temperature and humidity for a long time. The water outlet pipe 300 is affected by temperature and humidity, and stainless steel has good corrosion resistance and oxidation resistance, thereby reducing the influence of temperature and humidity on the water outlet pipe 300, so that the stability of the water outlet pipe 300 is better.

[0033] In some embodiments, the pulling pipe 100 and the first end of the sleeve pipe 200 are connected by threads, so that the pulling pipe 100 and the sleeve pipe 200 can be detachably connected, facilitating replacement or maintenance of the pulling pipe 100 and / or the sleeve pipe 200.

[0034] In some embodiments, the water outlet pipe 300 and the second end of the sleeve pipe 200 are connected by threads, so that the pulling pipe 100 and the sleeve pipe 200 can be detachably connected, facilitating replacement or maintenance of the pulling pipe 100 and / or the sleeve pipe 200.

[0035] In some embodiments, a first external thread (not shown in the figure) is arranged on the circumferential outer side wall of the end of the pulling pipe 100 close to the sleeve pipe 200, and a first internal thread (not shown in the figure) is arranged on the circumferential inner side wall of the first end of the sleeve pipe 200. The pulling pipe 100 and the sleeve pipe 200 are detachably connected by the cooperation between the first external thread and the first internal thread.

[0036] It should be noted that since the pulling pipe 100 and the sleeve pipe 200 are connected by the first external thread and the first internal thread, the outer diameter of the end of the pulling pipe 100 close to the sleeve pipe 200 is less than or equal to the inner diameter of the first end of the sleeve pipe 200, thereby making the end of the pulling pipe 100 close to the sleeve pipe 200 extend into the first end of the sleeve pipe 200, thereby realizing connection through the cooperation of the first external thread and the first internal thread.

[0037] In some embodiments, a second external thread (not shown in the figure) is arranged on the circumferential outer sidewall of the water outlet pipe 300 near the end thereof close to the sleeve pipe 200, a second internal thread (not shown in the figure) is arranged on the circumferential inner sidewall of the second end of the sleeve pipe 200, and the water outlet pipe 300 and the sleeve pipe 200 are detachably connected through cooperation between the second external thread and the second internal thread.

[0038] It should be noted that, since the water outlet pipe 300 and the sleeve pipe 200 are connected through the second external thread and the second internal thread, the outer diameter of the end of the water outlet pipe 300 close to the sleeve pipe 200 is smaller than or equal to the inner diameter of the second end of the sleeve pipe 200, so that the end of the pull pipe 100 close to the sleeve pipe 200 can extend into the second end of the sleeve pipe 200, and the connection is realized through cooperation between the second external thread and the second internal thread.

[0039] In some embodiments, a first elastic sealing member (not shown in the figure) is arranged on the first external thread, which can be a sealing rubber strip or a rubber ring, and the first elastic sealing member can be fixed on the first external thread by means of bolts, clamps, adhesives, etc.

[0040] When the pull pipe 100 is connected with the sleeve pipe 200, the first external thread on the pull pipe 100 is butted with the first internal thread on the first end of the sleeve pipe 200, and the pull pipe 100 or the sleeve pipe 200 is rotated so that the first external thread cooperates with the first internal thread. During this process, the circumferential outer sidewall of the pull pipe 100 and the circumferential inner sidewall of the sleeve pipe 200 will extrude the first elastic sealing member, that is, the first external thread and the first internal thread will extrude the first elastic sealing member, so that the first elastic sealing member deforms and fills the gap between the first external thread and the first internal thread, thereby realizing the sealing effect and preventing the water in the pull pipe 100 and the sleeve pipe 200 from leaking.

[0041] Further, the first elastic sealing member can also be arranged on the first internal thread, which is not particularly limited as long as it can seal the gap between the first external thread and the first internal thread.

[0042] It should be noted that when the outer diameter of the pulling pipe 100 close to one end of the sleeve pipe 200 is smaller than the inner diameter of the first end of the sleeve pipe 200, the first elastic sealing member can fill the gap at the connection between the pulling pipe 100 and the sleeve pipe 200, so that the pulling pipe 100 can be connected with the sleeve pipe 200 to maintain a stable connection state. At the same time, since the first elastic sealing member is filled between the first outer thread and the first inner thread, the pulling pipe 100 or the sleeve pipe 200 can extrude the first elastic sealing member, and the first elastic sealing member can deform to realize a certain degree of movement between the pulling pipe 100 and the sleeve pipe 200, that is, the pulling pipe 100 and the sleeve pipe 200 can be in a non-parallel state, so that a certain buffering effect can be achieved to avoid hard connection between the pulling pipe 100 and the sleeve pipe 200 from breaking, and the first elastic sealing member can still achieve stable sealing effect during the shaking process between the pulling pipe 100 and the sleeve pipe 200 through the deformation of the first elastic sealing member.

[0043] In some embodiments, a second elastic sealing member (not shown in the figure) is arranged on the second outer thread, which can be a sealing rubber strip or a rubber ring. The second elastic sealing member can be fixed on the second outer thread by bolts, clamps, adhesives, etc.

[0044] When connecting the water outlet pipe 300 with the sleeve pipe 200, the second outer thread on the water outlet pipe 300 is butted with the second inner thread on the second end of the sleeve pipe 200, and the water outlet pipe 300 or the sleeve pipe 200 is rotated to make the second outer thread cooperate with the second inner thread. During this process, the circumferential outer wall of the water outlet pipe 300 and the circumferential inner wall of the sleeve pipe 200 will extrude the second elastic sealing member, that is, the second outer thread and the second inner thread will extrude the second elastic sealing member, so that the second elastic sealing member deforms and fills the gap between the second outer thread and the second inner thread, thereby achieving the sealing effect, so that the water in the water outlet pipe 300 and the sleeve pipe 200 will not leak.

[0045] Further, the second elastic sealing member can also be arranged on the second inner thread, which is not particularly limited as long as it can seal the gap between the second outer thread and the second inner thread.

[0046] It should be noted that when the outer diameter of the water outlet pipeline 300 near one end of the sleeve pipe 200 is smaller than the inner diameter of the second end of the sleeve pipe 200, the second elastic sealing member can fill the gap at the connection between the water outlet pipeline 300 and the sleeve pipe 200, so that the water outlet pipeline 300 can be connected with the sleeve pipe 200 to maintain a stable connection state. At the same time, since the second elastic sealing member is filled between the second external thread and the second internal thread, the water outlet pipeline 300 or the sleeve pipe 200 can extrude the second elastic sealing member, and the second elastic sealing member can deform to achieve a certain degree of movement between the water outlet pipeline 300 and the sleeve pipe 200, that is, the water outlet pipeline 300 and the sleeve pipe 200 can be in a non-parallel state, so that a certain buffering effect can be achieved, avoiding hard connection between the water outlet pipeline 300 and the sleeve pipe 200 from breaking, and the second elastic sealing member can still achieve stable sealing effect during the shaking process between the water outlet pipeline 300 and the sleeve pipe 200 through the deformation of the second elastic sealing member.

[0047] Embodiment 2

[0048] The difference between this embodiment and embodiment 1 is that at least one of the pulling pipeline 100 and the water outlet pipeline 300 is connected with the sleeve pipe 200 by clamping connection. It can be understood that the clamping connection can also preferably achieve quick connection or disassembly between the pulling pipeline 100 and / or the water outlet pipeline 300 and the sleeve pipe 200.

[0049] In summary, the above only describes the preferred embodiments of the present application, and any changes and modifications made within the scope of the application should be included in the scope of the present application.
