Description

Technical Field

[0001] This utility model relates to the field of pressure monitoring, and in particular to a real-time monitoring and conveying hydraulic device for steam pipelines. Background Technology

[0002] In the chemical industry, steam pipelines are often needed to transport steam to the work area for product production. They are widely used in petrochemical, power island and other fields. The safety and stability of their operation are directly related to the normal operation of production and economic benefits. In order to ensure the safety of steam transportation, detection devices are needed to monitor the hydraulic pressure of the transportation in real time.

[0003] Most existing real-time monitoring hydraulic devices for steam pipelines are equipped with direct-contact pressure measuring devices. During use, the pressure gauge is installed on the steam pipeline. However, steam pipelines are often hot, and the pressure measuring position is prone to overheating during long-term use, which affects the service life of the measuring device. Moreover, maintenance and replacement often require shutting down the steam pipeline, resulting in a decrease in the service life and ease of use of the pressure monitoring device.

[0004] Therefore, in view of the problems mentioned above, such as the pressure gauge measuring position being easily heated during use, which affects the service life of the measuring device, and the fact that maintenance and replacement mostly require shutting down the steam pipeline, resulting in a decrease in the service life and ease of use of the pressure monitoring device, a new real-time monitoring and conveying hydraulic device for steam pipelines can be designed. Utility Model Content

[0005] To overcome the problems of existing real-time monitoring and conveying hydraulic devices for steam pipelines, where the pressure gauge measuring position is easily heated during use, thus affecting the service life of the measuring device, and maintenance and replacement mostly require shutting down the steam pipeline, resulting in a decrease in the service life and ease of use of the pressure monitoring device.

The installation pipe is slidably connected to the inner side of the pipeline body. A support platform is fixedly connected to the upper end of the installation pipe. A rotating platform is provided on the inner side of the support platform. A handwheel is fixedly connected to the upper end of the rotating platform.

[0007] Preferably, the installation pipe and support platform are connected to the main body of the pipeline, and the height of the rotating platform is controlled by a handwheel and a threaded groove. The piston cooperates with the installation pipe to receive the steam pressure inside the main body of the pipeline and rises, thereby pushing the connecting rod and the limiting block, and the partition plate is used to reduce the escape of steam.

[0008] Preferably, a receiving pipe is fixedly connected to the upper end of the main pipe body, the installation pipe is slidably connected to the receiving pipe, a first connecting plate is fixedly connected to the upper end of the installation pipe, and a second connecting plate is fixedly connected between the installation pipe and the support platform.

A first spring is installed between the receiving groove and the piston, and a mounting bracket is fixed to the outside of the piston.

[0010] Preferably, a sealing plug is installed at the upper end of the mounting bracket, and a partition plug is installed at the lower end of the mounting bracket. The sealing plug and the partition plug are slidably connected to the mounting tube.

[0014] The beneficial effects of this utility model are:

[0015] The real-time monitoring and conveying hydraulic device for this steam pipeline connects to the main body of the pipeline through an installation pipe and a support platform. The height of the rotating platform is controlled by a handwheel and threaded groove, thereby sealing the pipeline to transport steam. A partition plate is used to reduce the escape of steam. During pressure measurement, a piston, in conjunction with the installation pipe, withstands the steam pressure inside the main body of the pipeline, thereby pushing the piston up. This pushes the connecting rod and the limit block, which in turn pushes the pressure measuring device to indirectly measure the pressure. This reduces the possibility of damage to the core pressure measuring device and allows for maintenance and replacement during steam transportation. Attached Figure Description

A rotating platform 9 is provided on the inner side of the support platform 6. A handwheel 10 is fixedly connected to the upper end of the rotating platform 9. A baffle plate 11 for isolating steam is fixedly connected to the lower end of the rotating platform 9. A threaded groove 12 is provided on the outer side of the rotating platform 9. The rotating platform 9 and the support platform 6 are threadedly connected through the threaded groove 12. A receiving groove 13 is provided on the inner side of the rotating platform 9. A limit block 14 is provided on the upper end of the rotating platform 9. A connecting rod 15 is fixedly connected to the lower end of the limit block 14. The connecting rod 15 is slidably connected to the rotating platform 9. A piston 16 for sensing pipeline pressure is installed on the lower end of the connecting rod 15. The device is connected to the pipeline body 1 through the installation pipe 4 and the support platform 6, and controlled by the handwheel 10 and the threaded groove 12. The height of the rotating platform 9 is increased by the piston 16 in conjunction with the installation pipe 4 to receive the steam pressure inside the main body of the pipe 1, thereby pushing the connecting rod 15 and the limiting block 14, and using the partition plate 11 to reduce the escape of steam. The upper end of the main body of the pipe 1 is fixedly connected to the receiving pipe 2, and the installation pipe 4 is slidably connected to the receiving pipe 2. The upper end of the installation pipe 4 is fixedly connected to the first connecting plate 3, and the second connecting plate 5 is fixedly connected between the installation pipe 4 and the support platform 6. The installation pipe 4 is fixed to the inside of the receiving pipe 2 through the first connecting plate 3 and the second connecting plate 5. An external pipe 7 is provided at one end of the support platform 6. The front and rear ends of the support platform 6 are rotatably connected to the rotating frame 8 through the rotating shaft. A first spring 17 is installed between the receiving groove 13 and the piston 16. An installation frame 18 is fixedly connected to the outside of the piston 16. The external pipe 7 connects the inside and outside of the installation pipe 4 to facilitate the connection of other pipes for depressurization and other operations, and facilitates the movement of the piston 16 through the receiving groove 13 and the first spring 17.

[0024] Please see Figures 3-5In this embodiment, a sealing plug 19 is installed at the upper end of the mounting bracket 18, and a partition plug 20 is installed at the lower end of the mounting bracket 18. The sealing plug 19 and the partition plug 20 are slidably connected to the mounting pipe 4. The sealing plug 19 and the partition plug 20 are used to improve the performance of the piston 16 and reduce steam escape and heat damage to the equipment. A lifting platform 21 is slidably connected to the upper end of the rotating bracket 8. Fixed brackets 22 are fixed to both ends of the lifting platform 21. The lifting platform 21 improves the flexibility of equipment installation. A lifting pipe 23 is slidably connected to the inner side of the lifting platform 21. The pressure sensor body 24 is slidably connected to the inner side of the 3. The pressure sensor body 24 is triggered by the connecting rod 15 and the limiting block 14 to indirectly measure the hydraulic pressure of the steam pipeline. A third connecting plate 25 is installed on the outer side of the pressure sensor body 24. The third connecting plate 25 is bolted to the lifting pipe 23. Both ends of the lifting pipe 23 are rotatably connected to threaded rods 26 through rotating joints. The threaded rods 26 are threaded to the fixing frame 22. The threaded rods 26 cooperate with the fixing frame 22 to drive the lifting pipe 23 to rise and fall, so as to facilitate the loading and unloading of equipment and quickly release pressure to prevent equipment damage.

[0025] During installation, firstly, the main body of the pipe is connected to the pipe body 1 through the installation pipe 4 and the support platform 6, and the installation pipe 4 is fixed to the inside of the receiving pipe 2 using the first connecting plate 3 and the second connecting plate 5. Next, the height of the rotating platform 9 is controlled by the handwheel 10 and the threaded groove 12, and the escaping steam is reduced by the partition plate 11. Then, the inside and outside of the installation pipe 4 are connected through the external pipe 7 to facilitate the connection of other pipes for pressure relief and other operations. Finally, the height and position of the lifting platform 21 are adjusted by the rotating frame 8, and the pressure sensor body 24 is installed through the lifting pipe 23 and the third connecting plate 25. The pressure sensor body 24 used in this device is model CYYZ11.

[0026] In use, firstly, the piston 16 is moved conveniently by the receiving groove 13 and the first spring 17, and the piston 16 is raised by the installation pipe 4 to receive the steam pressure inside the pipe body 1. Then, the piston 16 is improved by the sealing plug 19 and the isolation plug 20, reducing the steam escape and heat damage to the equipment, and pushing the connecting rod 15 and the limiting block 14. Then, the pressure sensor body 24 is triggered by the connecting rod 15 and the limiting block 14 to indirectly measure the hydraulic pressure of the steam pipeline. The lifting pipe 23 can be raised and lowered by the threaded rod 26 and the fixed frame 22 to load and unload the equipment and quickly release pressure to prevent equipment damage. Finally, the rotating table 9 is rotated by the handwheel 10 to lift the partition plate 11 and connect the inside and outside of the pipe body 1 through the external pipe 7.

[0027] Through the above steps, the installation pipe 4 and support platform 6 are connected to the main body of the pipeline. The height of the rotating platform 9 is controlled by the handwheel 10 and the threaded groove 12. The piston 16, in conjunction with the installation pipe 4, receives the steam pressure inside the main body of the pipeline and rises, thereby pushing the connecting rod 15 and the limiting block 14. The partition plate 11 is used to reduce the escape of steam. This solves the problem that in the existing real-time monitoring and conveying hydraulic device for steam pipelines, the pressure gauge measuring position is easily heated during use, which affects the service life of the measuring device. Moreover, maintenance and replacement often require shutting down the steam pipeline, resulting in a decrease in the service life and ease of use of the pressure monitoring device.
