[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] The connecting mechanism 3 is arranged at the top of the second connecting pipe 2. The connecting mechanism 3 includes the first housing 301. The bottom of the first housing 301 is fixedly connected to the top of the second connecting pipe 2 through a flange. The bottom of the inner wall of the first housing 301 is fixedly connected with the third connecting pipe 302. The outer wall of the third connecting pipe 302 is provided with a clamping groove 303. The bottom of the inner wall of the first housing 301 is provided with a sealing groove 304. The groove wall of the sealing groove 304 is fixedly connected with a sealing strip 307. The inner wall of the first housing 301 is fixedly connected with a first guiding block 305. The bottom of the inner wall of the first housing 301 is provided with a locking mechanism 31;

[0034] The sealing mechanism 4 is arranged inside the first housing 301. The sealing mechanism 4 includes the second housing 401. The outer wall of the second housing 401 is inserted into the inner wall of the first housing 301. A transmitter assembly 5 is fixedly connected to the top of the second housing 401. A diaphragm 404 is fixedly connected to the inner wall of the second housing 401. An assembly groove 402 is formed in the inner wall of the second housing 401. A pressing block 405 is fixedly connected to the groove wall of the assembly groove 402. A locking block 403 is slidably connected to the inner wall of the second housing 401. The first guiding block 305 is used to limit the second housing 401. When the corrosion-resistant and wear-resistant pressure transmitter that is easy to install is put into use, the first connecting pipe 1 is connected to the conveying pipeline to be detected through a flange. After the connection of the first connecting pipe 1 is completed, the second housing 401 is aligned with the first guiding block 305, and the second housing 401 is pressed downward, so that the second housing 401 slides on the outer wall of the first guiding block 305 and the inner wall of the first housing 301, driving the locking mechanism 31 to contact the inner wall of the assembly groove 402, and enabling the locking mechanism 31 to slide in the sliding groove 306. During the sliding process of the locking mechanism 31 in the sliding groove 306, it rotates inside the assembly groove 402 and contacts the outer wall of the pressing block 405, and slides on the inclined surface at the bottom of the pressing block 405, driving the locking mechanism 31 to drive the second housing 401 to squeeze the sealing strip 307, causing the sealing strip 307 to deform to seal the second housing 401, and at the same time retracting into the sealing groove 304, so that the second housing 401 isolates the sealing strip 307. During the rotation of the locking mechanism 31 in the assembly groove 402, it squeezes the locking block 403, causing the locking block 403 to slide on the inner wall of the second housing 401 and contact the groove wall of the clamping groove 303 formed outside the third connecting pipe 302 to limit the locking block 403. The locking mechanism 31 and the third connecting pipe 302 simultaneously squeeze the locking block 403, causing the locking block 403 to generate a downward pressure on the second housing 401 to lock the second housing 401. At the same time, the locking mechanism 31 slides on the outer wall of the pressing block 405 to the high point of the inclined surface and is clamped with the inner wall of the assembly groove 402, so that the second housing 401 and the first housing 301 are kept sealed. After the installation is completed, the corrosive liquid flows into the buffer tank 6 through the first connecting pipe 1 and then enters the second connecting pipe 2, and is then led out through the third connecting pipe 302. The corrosive liquid squeezes the diaphragm 404 to cause the diaphragm 404 to deform, and the transmitter assembly 5 measures and reads the pressure value of the displacement after the deformation of the diaphragm 404;

[0035] The outer wall of the locking block 403 penetrates the inner wall of the second housing 401 and is clamped with the groove wall of the clamping groove 303. The bottom of the second housing 401 contacts the outer wall of the sealing strip 307 and is press-connected to the sealing strip 307. The diaphragm 404 is used for the transmitter assembly 5 to detect the pressure. During the rotation of the locking mechanism 31 in the assembly groove 402, it squeezes the locking block 403, causing the locking block 403 to slide on the inner wall of the second housing 401 and contact the groove wall of the clamping groove 303 formed outside the third connecting pipe 302 to limit the locking block 403. The locking mechanism 31 and the third connecting pipe 302 simultaneously squeeze the locking block 403, causing the locking block 403 to generate a downward pressure on the second housing 401 to lock the second housing 401.

A second guiding block 313 is fixedly connected to the surface of the limiting plate 311. The limiting groove 312 is used to guide the locking component 32. During the process of the second housing 401 being pressed and installed under the guidance of the first guiding block 305, the locking component 32 contacts the inner wall of the assembly groove 402, guiding the locking component 32 to slide in the sliding groove 306 and the limiting groove 312, and driving the limiting plate 311 to rotate on the inner wall of the first housing 301. While the limiting plate 311 rotates on the inner wall of the first housing 301, the second guiding block 313 contacts the inner wall of the assembly groove 402 and slides along the inner wall of the assembly groove 402. During the rotation of the second guiding block 313 on the inner wall of the assembly groove 402, the second guiding block 313 contacts the outer wall of the locking block 403 and exerts extrusion on the locking block 403, causing the locking block 403 to slide on the inner wall of the second housing 401 and contact the inner wall of the card slot 303 provided outside the third connecting pipe 302, limiting the locking block 403. The second guiding block 313 and the third connecting pipe 302 simultaneously exert extrusion on the locking block 403, causing the locking block 403 to exert a downward pressure on the second housing 401, locking the second housing 401;

[0037] The outer wall of the second guiding block 313 contacts the inner wall of the assembly groove 402 and slides along the inner wall of the assembly groove 402. The outer wall of the second guiding block 313 contacts the outer wall of the locking block 403 and slides on the outer wall of the locking block 403. The two ends of the limiting groove 312 are concentric with the two ends of the sliding groove 306. The second guiding block 313 is used to limit the sliding of the locking block 403 on the inner wall of the second housing 401. During the process of the locking component 32 driving the limiting plate 311 to rotate on the inner wall of the first housing 301, the limiting plate 311 drives the second guiding block 313 to contact the outer wall of the locking block 403 and exert extrusion on the locking block 403, causing the locking block 403 to slide on the inner wall of the second housing 401 and contact the inner wall of the card slot 303 provided outside the third connecting pipe 302, limiting the locking block 403. The second guiding block 313 and the third connecting pipe 302 simultaneously exert extrusion on the locking block 403, causing the locking block 403 to exert a downward pressure on the second housing 401, locking the second housing 401.

[0038] Embodiment 3. Based on Embodiment 2, please refer to Figures 6-7, the present invention provides a technical solution: The locking assembly 32 includes a support rod 321.

The support rod 321 is used to limit the support sleeve 325. During the process of the second housing 401 being pressed and installed under the guidance of the first guide block 305, the ball 326 contacts the inner wall of the assembly groove 402. Under the extrusion of the second housing 401, the ball 326 rolls along the inclined surface of the inner wall of the assembly groove 402 under the support of the support rod 321 and the support sleeve 325, and drives the support rod 321 to squeeze the first spring 322 and slide in the sliding groove 306 and the limiting groove 312;

[0039] A support block 323 is slidably connected to the outer wall of the support rod 321. A second spring 327 is fixedly connected to the bottom of the support block 323, and the other end of the second spring 327 is fixedly connected to the inner wall of the support rod 321. A pressure wheel 324 is rotatably connected to the outer wall of the support block 323 through a bearing. The support block 323 is used to limit the pressure wheel 324.

When the pressure wheel 324 slides to the high point of the pressure block 405, the support sleeve 325 squeezes through the third spring 328 to make the ball 326 roll to the groove formed in the groove wall of the assembly groove 402 to limit the ball 326, and then the transmitter assembly 5 is installed successfully;

[0041] The outer wall of the pressure wheel 324 contacts the groove wall of the assembly groove 402 and rolls along the groove wall of the assembly groove 402. The outer wall of the pressure wheel 324 contacts the outer wall of the pressure block 405 and slides along the direction of the pressure block 405.
