Description

Technical Field

[0001] This utility model relates to the field of transmitter technology, and more specifically to an intelligent pressure transmitter for high-pressure pipelines. Background Technology

[0002] With the rapid advancement of global industrialization and the continuous expansion of industrial production scale, the requirements for automated control of production processes are becoming increasingly stringent. Traditional pressure measurement and control methods can no longer meet the needs of complex and ever-changing industrial sites. Intelligent pressure transmitters have emerged to address this need. These transmitters provide an accurate and reliable data foundation for industrial automation control by continuously and accurately measuring process parameters such as pressure, differential pressure, and absolute pressure.

[0003] However, existing transmitters used in pipelines require the entire device to be dismantled for subsequent maintenance and replacement of transmitter elements, which is quite inconvenient.

[0004] In addition, existing transmitters are threaded, which makes the connection between the device and the pipeline prone to loosening due to water flow impact and vibration.

[0005] To address the aforementioned issues, this application provides an intelligent pressure transmitter for high-pressure pipelines. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides an intelligent pressure transmitter for high-pressure pipelines to solve the problems existing in the background art.

[0007] This utility model provides the following technical solution: a smart pressure transmitter for high-pressure pipelines, comprising a main body assembly and a detection assembly installed in the main body assembly, wherein a top cover assembly is installed on the top of the main body assembly, a fixing assembly is installed in the middle of the main body assembly, and a positioning assembly is provided on the lower side of the fixing assembly;

[0008] Preferably, the main component includes a high-pressure water pipe, an alloy pipe, a threaded pipe, a convex ring, and a retaining ring, wherein the threaded pipe is fixedly sleeved at the bottom of the alloy pipe, the threaded pipe's threads penetrate the high-pressure water pipe, the convex ring is fixedly sleeved at the top of the alloy pipe, and the retaining ring is fixedly sleeved inside the alloy pipe.

[0009] Preferably, the detection assembly includes a first mounting block, a second mounting block, a sealing ring, a strain gauge, a solenoid valve, and a display. The first mounting block is fixedly fitted with the second mounting block at its top. The sealing ring is movably fitted inside the alloy tube and positioned between the second mounting block and the retaining ring. The strain gauge is fixedly installed at the lower end of the first mounting block. The solenoid valve is positioned below the strain gauge and fixedly fitted inside the threaded tube. The display is fixedly installed above the upper cover assembly. When using the device, the solenoid valve is opened to connect the inner tube of the threaded tube and the high-pressure water pipe. At this time, the strain gauge obtains the current water pressure status and sends a signal to the display for display.

[0010] Preferably, the upper cover assembly includes an upper cover body, a push block, a rubber pad, a first threaded rod, and a threaded sleeve. The upper cover body is fitted directly above the convex ring. The push block is located at the bottom of the upper cover body and is movably fitted onto the inner tube of the alloy tube. The rubber pad is positioned above the second mounting block and is fixedly attached to the lower end of the push block. The first threaded rod is circumferentially and uniformly fixedly welded onto the convex ring. The upper end of the first threaded rod movably passes through the upper cover body and is threadedly fitted onto the threaded sleeve. During subsequent maintenance and sensor replacement, the threaded sleeve is unscrewed, and the upper cover body and its fixedly connected components are pulled out. The second mounting block and its connected first mounting block and strain gauge are then removed. During subsequent replacement and installation, the installation is performed by reversing the above-described operation. The sealing rubber ring is squeezed by the second mounting block during installation, thereby effectively sealing the connection.

[0011] Preferably, the fixing assembly includes a limiting ring, a limiting sleeve, a fixing plate, a sliding member, a second threaded rod, a knob, and a clamp. The limiting ring is sleeved on the outside of the alloy tube. The limiting sleeve rotates to fit the alloy tube and the limiting ring. The fixing plate is fixedly clamped on the outside of the limiting sleeve. The sliding member is slidably connected to both sides of the fixing plate. One end of the second threaded rod is threaded through the sliding member and rotated to clamp the fixing plate. The other end is fixedly sleeved to the knob. The clamps are fixedly installed on both ends of the outside of the sliding member. When the knobs on both sides and the second threaded rod fixedly sleeved to them are rotated, the sliding members on both sides move towards the center under the action of the threaded connection, and drive the clamps to move towards the center, thereby clamping the high-pressure water pipe.

[0012] Preferably, the positioning component includes a positioning ring, anti-slip texture, and internal thread. The positioning component is disposed between the high-pressure water pipe and the fixing plate. The inner ring of the positioning ring has an internal thread and is threaded onto the threaded pipe. The outer ring of the positioning ring has anti-slip texture evenly distributed around its circumference. In this case, the positioning ring can be threaded onto the threaded pipe through the internal thread.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] The design of the top cover assembly allows for quick replacement of strain gauges without disassembling the entire device, improving subsequent maintenance speed. At the same time, the design of the positioning and fixing components ensures that the inserted threaded tube will not loosen due to vibration from the high-pressure water flow, improving the stability of the device installation.

The convex ring 104 is fixedly sleeved at the top of the alloy pipe 102, and the retaining ring 105 is fixedly sleeved inside the alloy pipe 102.

[0024] Reference Figure 2 The detection component 2 includes a first mounting block 201, a second mounting block 202, a sealing ring 203, a strain gauge 204, a solenoid valve 205, and a display 206. The top of the first mounting block 201 is fixedly sleeved on the second mounting block 202. The sealing ring 203 is movably sleeved inside the metal tube 102 and is located between the second mounting block 202 and the retaining ring 105. The strain gauge 204 is fixedly installed at the lower end of the first mounting block 201. The solenoid valve 205 is located below the strain gauge 204 and is fixedly sleeved on the inner tube of the threaded tube 103. The display 206 is fixedly installed above the upper cover component 3. When using the device, the solenoid valve 205 is opened to connect the inner tube of the threaded tube 103 and the high-pressure water pipe 101. At this time, the strain gauge 204 obtains the current water pressure status and sends a signal to the display 206 for display.

[0025] Reference Figure 2 and Figure 3 The upper cover assembly 3 includes an upper cover body 301, a push block 302, a rubber pad 303, a first threaded rod 304, and a threaded sleeve 305. The upper cover body 301 is fitted directly above the convex ring 104. The push block 302 is located at the bottom of the upper cover body 301 and is movably fitted into the inner tube of the alloy tube 102. The rubber pad 303 is positioned above the second mounting block 202 and fixedly attached to the lower end of the push block 302. The first threaded rod 304 is uniformly welded to the convex ring 104 in a circular pattern. 4. The upper end moves through the upper cover 301 and is threadedly connected to the screw sleeve 305. When the sensor is replaced in the subsequent maintenance, the screw sleeve 305 is unscrewed, the upper cover 301 and the parts fixedly connected to it are pulled out, and the second mounting block 202 and the first mounting block 201 and strain gauge 204 connected to it are taken out. When the sensor is replaced and installed in the subsequent replacement, the installation is carried out by the reverse operation described above. The sealing ring 203 is squeezed by the second mounting block 202 during installation, thereby effectively sealing the connection.

[0026] Reference Figure 2 and Figure 4 The fixing component 4 includes a limiting ring 401, a limiting sleeve 402, a fixing plate 403, a sliding member 404, a second threaded rod 405, a knob 406, and a clamp 407. The limiting ring 401 is sleeved on the outside of the alloy tube 102. The limiting sleeve 402 rotates to sleeve the alloy tube 102 and the limiting ring 401. The fixing plate 403 is fixedly clamped on the outside of the limiting sleeve 402. The sliding member 404 is slidably connected to both sides of the fixing plate 403. One end of the second threaded rod 405 is threaded through the sliding member 404 and rotates to clamp the fixing plate 403. The other end is fixedly sleeved to the knob 406. The clamp 407 is fixedly installed on both ends of the outside of the sliding member 404. When the knob 406 on both sides and the second threaded rod 405 fixedly sleeved to it are rotated, the sliding member 404 on both sides moves towards the center under the action of the threaded connection, and drives the clamp 407 to move towards the center, thereby clamping the high-pressure water pipe 101.

[0027] Reference Figure 2 and Figure 3 The positioning component 5 includes a positioning ring 501, anti-slip texture 502, and internal thread 503. The positioning component 5 is disposed between the high-pressure water pipe 101 and the fixing plate 403. The inner ring of the positioning ring 501 has an internal thread 503 and is threadedly connected to the threaded pipe 103. The outer ring of the positioning ring 501 has anti-slip texture 502 that is evenly distributed around the circumference. At this time, the positioning ring 501 can be threadedly connected to the threaded pipe 103 through the internal thread 503.

[0028] The working principle of this utility model is as follows: When using this device, the solenoid valve 205 is opened, connecting the inner tube of the threaded pipe 103 and the high-pressure water pipe 101. At this time, the strain gauge 204 acquires the current water pressure status and sends a signal to the display 206 for display. When installing the device, the threaded pipe 103 is rotated to move it to the designated position on the high-pressure water pipe 101. Then, the knobs 406 on both sides and the second threaded rod 405 fixedly connected to them are rotated. Under the action of the threaded connection, the sliding parts 404 on both sides move towards the center, thereby driving the gripper 407 to move towards the center and clamping the device. Tighten the high-pressure water pipe 101. At this time, rotate the positioning component 5 to make it press against the fixing component 4, so that the main component 1 and the fixing component 4 are relatively fixed, thus completing the installation. When the sensor is replaced in the subsequent maintenance, unscrew the screw sleeve 305, pull out the upper cover 301 and the parts fixedly connected to it, and further take out the second mounting block 202 and the first mounting block 201 and strain gauge 204 connected to it. When replacing and installing in the future, the installation is carried out by reversing the operation described above. The sealing ring 203 is squeezed by the second mounting block 202 during installation, thereby effectively sealing the connection.
