Description

Technical Field

[0001] The utility model relates to the field of pressure gauge connection, in particular to a pressure gauge connection device. Background Art

[0002] The pressure gauge connection device is a device used to connect the pressure gauge to the system under test. Its design purpose is to ensure that the pressure gauge can accurately measure the pressure in the system and can be installed and maintained safely and reliably. The flange is a flange connection device used to connect the pressure gauge and the system under test. The gasket is placed at the flange connection to ensure the sealing of the connection. The bolts are used to tighten the flange or other connecting parts to ensure the firmness and sealing of the connection. The selection of the pressure gauge connection device depends on the characteristics of the system under test, the installation environment, and the design requirements of the pressure gauge itself. A good connection device can ensure the accuracy of pressure measurement and the safety of the system.

[0003] In the specific connection of the pressure gauge, the pressure gauge is usually installed on the pressure gauge joint when measuring the pressure. The traditional pressure gauge and the pipeline are connected by a threaded connection, and the connection is poor in firmness and stability. After long-term use, the thread is easy to loosen and detach, causing the liquid or gas in the pipeline to leak from the joint, thereby affecting the measurement of the pressure gauge and making it inconvenient for the operator to use.

When installed inside the annular groove 16, the operator can rotate the connecting block 13 and rotate it inside the annular groove 16. When it is rotated to touch the insertion rod 17, the operator can pull the two groups of insertion rods 17, and the two groups of insertion rods 17 drive the tension spring 19 to be compressed. Then the operator rotates the connecting block 13 to be parallel to the insertion rod 17. At this time, the operator can release his hand, and the tension spring 19 rebounds, so that the two groups of insertion rods 17 can be inserted into the inside of the mounting hole 14, limit the assembly tube 12, and then the pressure gauge body 27 can be installed firmly and stably.

[0029] Reference Figure 1-Figure 6In a preferred embodiment, a sealing groove 21 is provided at the top of the mounting tube 11, a sealing ring 22 is provided inside the sealing groove 21, slots 25 are provided inside both sides of the mounting tube 11, sealing rings 26 are provided inside the two sets of slots 25, a pressure gauge body 27 is provided at the top of the assembly tube 12, a connecting tube 23 is provided at the bottom of the mounting tube 11, a circular ring 2 is fixed on the surface of the assembly tube 12, and by providing the circular ring 2, the sealing ring 22 can be squeezed to improve its sealing performance, the size of the circular ring 2 is adapted to the size of the sealing groove 21, the size of the connecting block 13 is adapted to the size of the mounting groove 15, the annular groove 16 is connected to the mounting groove 15, a pull ring 24 is provided at one end of the insertion rod 17, and a tension spring 19 is provided between the pull ring 24 and the slot 25, through the pressure gauge body 27, the connecting block 13, the annular groove 16, the circular ring 2 , the sealing ring 22, the insertion rod 17 and the sealing ring 26 cooperate with each other, so that when the operator needs to improve the test effect of the pressure gauge body 27, the operator can insert the connecting block 13 into the annular groove 16, and the ring 2 on the surface of the assembly tube 12 can be inserted into the inside of the sealing groove 21. Since the sealing ring 22 is arranged inside the sealing groove 21, when the operator rotates the connecting block 13 at this time, the sealing ring 22 can seal the connection of the pressure gauge body 27, and when the insertion rod 17 is inserted into the inside of the mounting hole 14, the pull rod 18 can be inserted into the inside of the slot 25. Since the inside of the slot 25 is provided with a sealing ring 26, the limit position of the insertion rod 17 can be sealed, thereby improving the overall sealing of the device, so that the liquid or gas in the pipeline of the pressure gauge body 27 will not leak, thereby improving the measurement effect of the pressure gauge body 27.

[0030] Reference Figure 1-Figure 6 In a preferred embodiment, two groups of sealing rings 26 are arranged on the opposite sides of the two groups of pull rods 18, and the size of the plug rod 17 is adapted to the size of the mounting hole 14. Through the above arrangement, when the tension spring 19 rebounds, the plug rod 17 can be inserted into the inside of the mounting hole 14, the ring 2 is arranged above the connecting block 13, the slot 25 is connected to the annular groove 16, the size of the connecting block 13 is adapted to the size of the annular groove 16, and the bottom of the assembly tube 12 is arranged inside the connecting tube 23. By setting the assembly tube 12 at the connecting tube 23, it can be directly connected to the pipeline to be tested, and the pipeline to be tested can be tested.

[0031] Specifically, the working process or working principle of the pressure gauge connection device is as follows: in the specific pressure gauge connection, the pressure gauge is usually installed on the pressure gauge joint when measuring the pressure. The traditional pressure gauge and the pipeline are connected by a threaded connection, and the connection is relatively poor in firmness and stability. After long-term use, the thread is easy to loosen and detach, causing the liquid or gas in the pipeline to leak from the joint, thereby affecting the measurement of the pressure gauge and making it inconvenient for the operator to use. Therefore, the technical solution can solve the above problem. When the operator needs to connect the pressure gauge body 27, the operator can first align the two sets of connection blocks 13 on the assembly pipe 12 for installation. There are two sets of mounting grooves 15 inside the tube 11, and then the connecting block 13 is installed inside the mounting tube 11. When it is installed inside the annular groove 16, the operator can rotate the connecting block 13 and rotate it inside the annular groove 16. When it is rotated to touch the plug rod 17, the operator can pull the two sets of plug rods 17, and the two sets of plug rods 17 drive the tension spring 19 to compress. Then the operator rotates the connecting block 13 to be parallel to the plug rod 17. At this time, the operator can release his hand, and the tension spring 19 rebounds, so that the two sets of plug rods 17 can be inserted into the inside of the mounting hole 14, and the assembly tube 12 is limited, so that the pressure gauge body can be made 27 is firmly and stably installed. After the installation is completed, the operator can install the pipe to be tested into the inside of the connecting pipe 23, so that the pipe to be tested can be tested. When used for a long time, the operator can pull the two sets of plug rods 17 to release the limit of the connecting block 13, and then the operator can rotate the connecting block 13. Finally, the assembly pipe 12 and the pressure gauge body 27 can be directly taken out, so that the pressure gauge body 27 can be disassembled for the convenience of the operator to use. When the operator needs to improve the test effect of the pressure gauge body 27, the operator can insert the connecting block 13 into the annular groove 16, and the annular groove on the surface of the assembly pipe 12 can be opened. 2 can be inserted into the sealing groove 21. Since a sealing ring 22 is provided inside the sealing groove 21, when the operator rotates the connecting block 13, the sealing ring 22 can seal the connection of the pressure gauge body 27. When the insertion rod 17 is inserted into the installation hole 14, the pull rod 18 can be inserted into the slot 25. Since a sealing ring 26 is provided inside the slot 25, the limit of the insertion rod 17 can be sealed, thereby improving the overall sealing of the device, so that the liquid or gas in the pipeline of the pressure gauge body 27 will not leak, and the measurement effect of the pressure gauge body 27 is improved. At this point, all processes are completed.

[0032] It should be noted that the pressure gauge body 27 is electrically connected to the external power supply and is a device or equipment existing in the prior art, or is a device or equipment that can be realized in the prior art.
