The top of the water outlet pipe 10 passes through the installation sleeve 1 and extends to the inside of the installation sleeve 1. The inner wall of the annular cavity 8 is slidably connected with a piston plate 11. The shape of the piston plate 11 is annular. The top of the piston plate 11 is fixedly connected to two springs 12 and two connecting rods 13. The tops of the two springs 12 are fixedly connected to the inner wall of the annular cavity 8. The tops of the two connecting rods 13 pass through and extend to the inside of the installation sleeve 1. A cleaning plate 14 is fixedly connected between the two connecting rods 13. , the cleaning plate 14 is sleeved on the electrode of the body 2 and is slidably connected thereto; the clamping mechanism 3 includes two sets of annularly distributed screw rods 301, one end of each set of annularly distributed screw rods 301 is inserted into the mounting sleeve 1 and slidably connected thereto, the bottom ends of the two sets of screw rods 301 are fixedly connected with blocks 302, the outer sides of the two sets of blocks 302 are slidably connected to the inner wall of the mounting sleeve 1, and the two sets of screw rods 301 are sleeved with threaded rings 303 threadedly connected thereto, and the bottoms of the two sets of threaded rings 303 are embedded in the mounting sleeve 1 and rotate with it. Connection; The sealing mechanism 4 includes two annular grooves 401, both of which are opened on the inner wall of the mounting sleeve 1, and the inner walls of the two annular grooves 401 are provided with rubber rings 402 and extrusion rings 403. The mounting sleeve 1 is rotatably connected to a screw rod 404, and a rotating knob 405 is provided on the screw rod 404. The top of the rotating knob 405 passes through and extends to the outside of the mounting sleeve 1, and two moving blocks 406 are provided on the screw rod 404 and are threadedly connected to it. One side of the two moving blocks 406 is fixedly connected to the two extrusion rings 403 respectively.

[0025] In the present invention, when in use, the pipe conveying the conductivity medium to be tested is inserted into the installation sleeve 1, and then the user rotates all the threaded rings 303. The threaded rings 303 are threadedly connected to the screw rod 301 and the blocks 302 have a limiting effect on the screw rod 301. Therefore, after the threaded rings 303 rotate, the screw rod 301 and the blocks 302 move. After all the blocks 302 are tightly attached to the pipe conveying the medium, the installation sleeve 1 is fixed. The body 2 is located on the installation sleeve 1, and the installation of the body 2 is achieved. The shell of the body 2 is made of stainless steel, which has good pressure resistance. After the installation of the body 2 is completed, use The user can drive the screw 404 to rotate by rotating the knob 405. Since the screw 404 is threadedly connected to the two moving blocks 406 and the screw 404 is double-threaded, the rotation of the screw 404 will drive the two moving blocks 406 to slide along the two grooves for sliding the moving blocks 406 opened in the installation sleeve 1. During the movement of the moving blocks 406, the two extrusion rings 403 will be driven to move toward each other. During the movement of the extrusion ring 403, the rubber ring 402 will be squeezed. After being squeezed, the rubber ring 402 will be deformed, and the inner side of the rubber ring 402 will move toward the medium pipeline. The inner side of the rubber ring 402 will then fit tightly against the pipeline, thereby achieving a sealing effect.

[0026] After the installation of the main body 2 is completed, the medium will flow into the inside of the installation sleeve 1 from the right pipe, and then the medium will enter the middle of the installation sleeve 1 from the conduit 6 and contact the electrode of the main body 2. At this time, the main body 2 will detect the conductivity of the medium to achieve the effect of detecting the conductivity of the medium.

[0027] Before testing the conductivity of the medium, the user first closes the solenoid valve 7. At this time, the medium in the right pipe will gather. Due to the pressure of the medium, the medium will enter the water inlet pipe 9 from the conduit 6 and then enter the annular cavity 8. As the medium gathers, the piston plate 11 will move up along the inner wall of the annular cavity 8. During the process, the spring 12 will be compressed until the piston plate 11 moves above the outlet pipe 10. The medium will be discharged from the outlet pipe 10 into the interior of the installation sleeve 1. During the process, the piston plate 11 will drive the cleaning plate 14 to rise through the two connecting rods 13. During the rising process, the cleaning plate 14 will slide along the electrode of the main body 2, thereby scraping off the dirt on the surface of the electrode, thereby achieving the effect of cleaning the electrode on the main body 2. After cleaning the main body 2, the user opens the solenoid valve 7. At this time, the medium can enter the middle part of the installation sleeve 1 from the conduit 6. The pressure in the annular cavity 8 decreases, the spring 12 will drive the piston plate 11 to move down, the cleaning plate 14 will be reset, and then the main body 2 can be used to measure the conductivity of the medium.

[0028] During the cleaning process of the main body 2, as the medium flows in the annular cavity 8, the medium will heat the mounting sleeve 1. The main body 2 is located at the center of the annular cavity 8, thereby preheating the main body 2 to a temperature close to that of the medium, thereby preventing thermal shock and maintaining stable sensor performance, thereby improving the practicality of the device.

[0029] See also Figures 1 to 3 , wherein: the mounting sleeve 1 is provided with two rotating rings 15 rotatably connected thereto, a ring-shaped handle 16 is fixedly connected between the two rotating rings 15, an outer side of the threaded ring 303 is provided with external teeth, and the two rotating rings 15 are provided with internal teeth meshing with the external teeth.

[0030] In the present invention, the user can drive the rotating ring 15 to rotate by pressing down the handle 16. After the rotating ring 15 rotates, it will drive all the threaded rings 303 to rotate, thereby achieving the effect of driving multiple blocks 302 to move at the same time, making it easier for the user to fix the installation sleeve 1.

[0031] See also Figure 3 , wherein: two sealing rings 17 are fixedly connected to the inner wall of the installation sleeve 1, and both sealing rings 17 are rubber layers.

[0032] In the present invention, the provision of the sealing ring 17 can enhance the sealing effect between the medium pipeline and the installation sleeve 1, thereby improving the practicability of the device.
