Description

Technical Field

[0001] This invention relates to the technical field of water supply pipelines, and more particularly to a pressure detection device for water supply pipelines. Background Technology

[0002] In water supply pipelines, pressure gauges are crucial devices that help monitor the pressure of the liquid within the pipes, ensuring the normal operation of the pipeline system. However, if a pressure gauge malfunctions or needs replacement, the entire supply process must be stopped for replacement, which undoubtedly causes inconvenience to production and the project. This is especially true in situations where continuous supply is critical, such as industrial production lines or water supply systems; a halt to supply may lead to production disruptions or water supply problems, placing additional pressure and challenges on relevant departments.

[0003] To avoid downtime due to pressure gauge malfunction, regular inspections and maintenance of pressure gauges are necessary to ensure their installation stability and accurate pressure measurement of the liquid in the pipeline. Currently, a common method for testing installation stability is to directly rotate the pressure gauge with a wrench to verify its stability. However, this method may lead to over-installation of the pressure gauge, thus affecting its performance and accuracy. Summary of the Invention

[0032] Example 1

[0033] Reference Figures 1-6 This is the first embodiment of the present invention, which provides a pressure detection device for a water supply pipeline. This device includes...

[0034] The installation mechanism 100 includes a connecting pipe 101, a connector 102 fixedly connected to the top of the connecting pipe 101, and a slot 103 formed on the inner wall of the connector 102. A sealing component 104 is provided at the bottom of the connector 102.

[0035] Specifically, the sealing component 104 includes a first spring 104a fixedly connected to the bottom end of the connector 102, a base plate 104b fixedly connected to the bottom end of the first spring 104a, and a blocking block 104c fixedly connected to the top end of the base plate 104b. The top end of the blocking block 104c is provided with a groove 104d.

[0036] Furthermore, the upper end of the inner wall of the connector 102 is provided with an internal thread, the plug 104c is slidably connected to the bottom end of the inner wall of the connector 102, and the opening direction of the groove 104d is the same as the direction of the connecting pipe 101.

[0037] Furthermore, it also includes,

[0038] The main structure 200 includes a threaded rod 201, a bottom rod 202 fixedly connected to the bottom end of the threaded rod 201, and a hexagonal screw head 203 fixedly connected to the top end of the threaded rod 201. Hydraulic oil 204 is filled inside the threaded rod 201 and the hexagonal screw head 203. A triggering component 205 is provided inside the hexagonal screw head 203. A protective component 206 is provided inside the threaded rod 201. A locking component 207 is provided on the outside of the bottom rod 202. A monitoring component 208 is adapted to be installed on the top end of the hexagonal screw head 203.

[0039] Preferably, the triggering component 205 includes a pressure rod 205a slidably connected inside the hexagonal screw head 203, and a first piston 205b fixedly connected to one end of the pressure rod 205a.

[0040] It should be noted that the protective component 206 includes a push rod 206a that is slidably connected inside the threaded rod 201, a rubber ring 206b that is fixedly connected to the bottom end of the push rod 206a, and a second piston 206c that is fixedly connected to the top end of the push rod 206a. A pressure block 206d is fixedly connected to the outside of the push rod 206a.

[0041] Hydraulic oil 204 is located between the first piston 205b and the second piston 206c, and a reset component 206e is provided on the outside of the push rod 206a.

[0042] Preferably, the reset component 206e includes a support rod 206e-1 fixedly connected to the outside of the top rod 206a, an outer ring 206e-2 fixedly connected to the outside of the support rod 206e-1, and a second spring 206e-3 fixedly connected to the top of the outer ring 206e-2. The other end of the second spring 206e-3 is fixedly connected to the inside of the threaded rod 201.

[0043] Preferably, the monitoring component 208 includes a pressure gauge 208a fixedly connected to the top of the hexagonal screw head 203, and a sensor 208b fixedly connected inside the threaded rod 201. The detection end of the sensor 208b protrudes from the bottom rod 202, and the sensor 208b is wired to the pressure gauge 208a.

[0044] In use, firstly, the wrench is used to clamp the two sides of the hexagonal screw head 203 where the pressure rod 205a is located. After the wrench is clamped, it will squeeze the pressure rod 205a into the interior of the hexagonal screw head 203. At the same time, in conjunction with the first piston 205b, hydraulic oil 204 and the second piston 206c, the push rod 206a and the rubber ring 206b at the bottom of the push rod 206a will slide down, so that the rubber ring 206b and the sensor 208b detection head are kept at the same horizontal plane.

[0045] Next, the base rod 202 is inserted into the connector 102, and the hexagonal screw head 203 is turned with a wrench, causing the threaded rod 201 to gradually connect with the connector 102. This eventually causes the rubber ring 206b to contact the top of the plug 104c. Turning the hexagonal screw head 203 further compresses the rubber ring 206b against the plug 104c until it cannot be turned further. At this point, the compression of the rubber ring 206b causes the plug 104c to leave the connector 102, simultaneously positioning the sensor 208b probe at the bottom of the base rod 202 inside the connecting tube 101, allowing it to detect the pressure of the liquid inside the connecting tube 101. The groove 104d design ensures that the liquid can fully contact the sensor 208b probe, thus ensuring the accuracy of the liquid pressure detection value.

[0046] Furthermore, if the wrench accidentally falls off during installation, the pressure rod 205a cannot be squeezed. In this case, the elasticity of the second spring 206e-3 will cause the push rod 206a, rubber ring 206b and other components to reset. At this time, the design of the groove 104d can also ensure that the block 104c cannot contact the probe of the sensor 208b, thus effectively protecting the probe of the sensor 208b and ensuring the accuracy of the liquid pressure detection value once again.

[0047] When pressure gauge 208a needs to be replaced during liquid transportation, simply reverse the hexagonal screw head 203. This will cause the base rod 202 to gradually slide upwards, and the plug 104c will be inserted into the connector 102 under the elasticity of the first spring 104a, achieving alternating sealing. This ensures that the pipeline can transport liquid normally after pressure gauge 208a is removed, and only a new pressure gauge needs to be replaced. During the installation process, the alternating sealing between the base rod 202 and the plug 104c will be achieved again, thus enabling the installation of pressure gauge 208a.

[0048] In summary, the actual installation of pressure gauge 208a allows for replacement without shutting down the system to clear the pipes, greatly ensuring the stability of the liquid supply. Furthermore, the installation of pressure gauge 208a also effectively protects the probe of sensor 208b, ensuring accurate detection of liquid pressure.

[0049] Example 2

[0050] Reference Figure 7 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the locking component 207 includes a rotating shaft 207a rotatably connected to the inner side of the base rod 202, and a locking block 207b fixedly connected to the outer side of the rotating shaft 207a.

[0051] Furthermore, the locking block 207b is designed in an L-shape, and the rotating shaft 207a is connected to the bottom rod 202 via a torsion spring.

[0052] The elasticity of the first spring 104a is greater than that of the second spring 206e-3.

[0053] After the installation is completed and the wrench is removed, the plug 104c pushes the rubber ring 206b completely into the bottom rod 202 under the elasticity of the first spring 104a. Thus, the pressure rod 205a is fully extended through the transmission of the top rod 206a, the second piston 206c, the hydraulic oil 204 and the first piston 205b. At this time, the appropriate wrench cannot squeeze one end of the pressure rod 205a to be stuck on the outside of the hexagonal screw head 203.

[0054] At the same time, the upward sliding of the push rod 206a will cause the pressure block 206d to squeeze the locking block 207b, causing the locking block 207b to rotate around the rotating shaft 207a, and finally lock into the inside of the slot 103, thus realizing the complete installation of the pressure gauge 208a.

[0055] In summary, once the installation is complete, the stability of the pressure gauge 208a after installation can be improved by the engagement of the locking block 207b with the locking slot 103. At the same time, it also makes it easier for inspection personnel to quickly judge the stability of the pressure gauge 208a installation by observing the distance extended by the pressure rod 205a during inspection work, thereby improving the inspection efficiency of the staff.

[0056] Example 3

[0057] Reference Figures 1 to 7 This is the third embodiment of the present invention, which differs from the second embodiment in that:

[0058] During the inspection, the inspectors can not only quickly determine the stability of the pressure gauge 208a installation by observing the distance extended by the pressure rod 205a, but also use a suitable wrench to clamp the other four sides of the hexagonal screw head 203 where the pressure rod 205a is not installed, and turn the wrench. Since the locking block 207b is located inside the locking groove 103, it cannot be rotated. Thus, the stability of the pressure gauge 208a installation can also be quickly determined by whether the hexagonal screw head 203 can be rotated.

[0059] When replacement is required, an adjustable wrench should be used. Position the two sides of the adjustable wrench on both sides of the hexagonal screw head 203 where the pressure rod 205a is located, and adjust the opening of the wrench so that the wrench engages with the hexagonal screw head 203. At this time, under the pressure, the pressure rod 205a will be moved into the hexagonal screw head 203. Then, rotate the adjustable wrench to complete the disassembly.
