Description

Technical Field

[0001] This utility model relates to the field of pressure gauge calibration technology, and in particular to a pressure gauge installation structure that allows for calibration without disassembly. Background Technology

[0002] Pumped storage power stations contain numerous pressure gauges connected to water pipelines to measure water pressure in the tailrace, spiral casing, and other waterways. These pressure gauges are connected to isolation valves via threads. According to the power station's technical supervision requirements, these pressure gauges need to be calibrated periodically. The calibration process involves closing the isolation valves, removing the pressure gauges, and installing them on calibration equipment. Because pressure gauge calibration is typically scheduled during the unit's routine maintenance, the large number of pressure gauges and the significant workload involved in disassembling and reassembling them, coupled with the risk of damage during this process and potential leaks at the threads if not properly reassembled, all contribute to this problem.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0028] It should be noted that, unless otherwise defined, the technical or scientific terms used in the embodiments of this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains.

[0029] The following describes the specific implementation process of this utility model with reference to the accompanying drawings.

[0030] like Figure 1 and Figure 2 As shown, this utility model provides a pressure gauge installation structure that allows for calibration without disassembly, comprising:

[0031] Water pipe 1, the water pipe 1 includes a main pipe 11 and branch pipes 12 disposed on the side wall of the main pipe 11;

[0032] Pressure gauge 2 is installed at the end of the main pipeline 11;

[0033] A quick-connect female head 3 is located at the end of the branch pipe 12. Its outer wall is fitted with a protective device 6 to protect the quick-connect female head 3. When the protective device 6 is open, the quick-connect female head 3 is connected to the testing equipment through the quick-connect female head so that the testing equipment can calibrate the pressure gauge 2.

[0034] Specifically, pressure gauge 2 is installed on the main pipe 11 of water pipe 1, and quick-connect female connector 3 is installed on the branch pipe 12. A protective device 6 is fitted onto the outer wall of quick-connect female connector 3 to protect it from corrosion and dirt accumulation, preventing dirt from entering water pipe 1 and pressure gauge 2 and causing damage or corrosion. When pressure gauge 2 needs to be calibrated, simply open the protective device 6 to expose quick-connect female connector 3 and connect it to quick-connect female connector. Pressure gauge 2 is then connected to the testing equipment via quick-connect female connector 3 and quick-connect female connector for calibration. This eliminates the need to disassemble pressure gauge 2 for calibration, saving calibration time and increasing calibration speed.

[0035] Furthermore, the quick coupling female head 3 and the quick coupling female head are flat quick couplings, that is, the quick couplings are flat quick couplings. For example, the quick coupling model can be KSP1-25-G1, hydraulic KSP1-FF high pressure carbon steel flat quick coupling.

[0036] In some embodiments, such as Figure 2 As shown, the main pipeline 11 includes a pipeline body 110 and a tee pipe 13. The tee pipe 13 includes a first pipe 131, a second pipe 132 and the branch pipeline 12 that are connected to each other. The first pipe 131 is connected to the pipeline body 110, and the second pipe 132 is connected to the pressure gauge 2.

[0037] Specifically, the main pipeline 11 includes a pipeline body 110 and a tee pipe 13, that is, the tee pipe 13 is installed on the pipeline body 110. Thus, the pressure gauge 2, the quick-connect female connector 3, and the pipeline body 110 can be connected through the tee pipe 13. In this embodiment, the tee pipe 13 includes a first pipe 131, a second pipe 132, and a branch pipe 12. The first pipe 131 can be understood as the inlet pipe connected to the pipeline body 110, the second pipe 132 can be understood as the first outlet pipe connected to the pressure gauge 2, and the second pipe 132 is located on the same horizontal line as the first pipe 131. The branch pipe 12 can be understood as the second outlet pipe connected to the quick-connect female connector 3, and the branch pipe 12 is perpendicular to the first pipe 131 and the second pipe 132. The pressure gauge 2 is connected to the testing equipment using the quick-connect female connector 3 and the quick-connect female connector, thereby enabling the calibration of the pressure gauge 2 without disassembling it for calibration.

[0038] In some embodiments, such as Figure 2 , Figure 3 and Figure 5 As shown, a first switch valve 5 is provided between the pipeline body 110 and the first pipe 131. The first port of the first switch valve 5 is connected to the outlet of the pipeline body 110, and the second port of the first switch valve 5 is connected to the first pipe 131 of the three-way pipe 13.

[0039] Specifically, the exemplary first switching valve 5 can be a ball valve, wherein, for example... Figure 2 and Figure 5 The switching and adjusting style of the first switching valve 5 can vary and can be selected according to specific circumstances; no specific limitation is made in this utility model. The first switching valve 5 is installed on the pipeline body 110 and is used to control the water flow in the pipeline body 110. When it is necessary to calibrate the pressure gauge 2, the testing equipment needs to inject water pressure into the pressure gauge 2. The first switching valve is installed between the pipeline body 110 and the tee pipe 13. Only by cutting off the water flow in the pipeline body 110 through the first switching valve can the accuracy of the pressure gauge 2 calibration be guaranteed.

[0040] In some embodiments, such as Figure 2 As shown, a second switch valve 4 is provided between the branch pipe 12 and the quick connector female 3. The first port of the second switch valve 4 is connected to the outlet of the branch pipe 12, and the second port of the second switch valve 4 is connected to the connector end of the quick connector female 3.

[0041] Specifically, in this embodiment, the tee pipe 13 is a standard tee pipe. The second switch valve 4 can be a ball valve. In the above embodiment, the branch pipe 12 is a tee pipe perpendicular to the first pipe 131 and the second pipe 132. A second switch valve 4 is installed between the branch pipe 12 and the quick-connect female connector 3 to block the water flow in the branch pipe 12. Since the quick-connect connector is only used when testing the pressure gauge 2, the second switch valve 4 on the branch pipe 12 can block the water flow from the branch pipe 12 to the quick-connect female connector 3 when the main pipe 11 is in use, preventing leakage from the quick-connect female connector 3. By placing the quick-connect female connector 3 on the branch pipe 12 and placing the pressure gauge 2 on the second pipe 132, the pressure gauge 2 can directly collect the water pressure of the main pipe 11, allowing the pressure gauge 2 to display the water pressure of the main pipe 11 in real time.

[0042] In some embodiments, such as Figure 3 and Figure 5 As shown, the three-way pipe 13 is a three-way valve.

[0043] Specifically, in this embodiment, the three-way pipe 13 can be a three-way valve, which can be a three-way ball valve. The three-way ball valve can adjust the water flow direction; for example, it can adjust the connection between the first pipe 131 and the second pipe 132 of the three-way pipe 13, the connection between the second pipe 132 and the branch pipe 12, and the connection between the first pipe 131 and the branch pipe 12. When the main pipeline 11 is in normal use, the three-way valve can be adjusted to ensure that its first pipe 131 and the second pipe 132 are connected, while its branch pipe 12 is closed. When calibrating the pressure gauge 2, the connection between the second pipe 132 and the branch pipe 12 is ensured, so that the testing equipment injects test pressure into the pressure gauge 2 via the branch pipe 12 and the second pipe 132 to calibrate the pressure gauge 2.

[0044] In some embodiments, such as Figure 2 , Figure 3 and Figure 4 As shown, the protection device 6 is a first protection device 61. The first protection device 61 includes a base 611 and a protective cover 612. The base 611 is sleeved on the outer wall of the quick connector female 3 and fixed by the locking bolt 6113. A threaded part 6111 is provided on one side wall of the base 611, and the protective cover 612 is threadedly connected to the threaded part 6111.

[0045] Specifically, in this embodiment, the protective device 6 adopts a first protective device 61, which includes a base 611 and a protective cover 612 connected to each other. The base 611 is sleeved on the outer wall of the quick connector female 3, and is fixed at the end of the quick connector female 3 near the tee pipe 13 by a locking bolt 6113. The protective cover 612 is fastened to the base 611. The side of the base 611 away from the tee pipe 13 is provided with a threaded part 6111, so that the protective cover 612 can be sleeved on the outer wall of the quick connector female 3 and threadedly connected to the base 611. In this way, the base 611 and the protective cover 612 protect the quick connector female 3, preventing corrosion and dirt accumulation caused by prolonged exposure. The base 611 is fixed to the outer wall of the quick connector female 3 by the locking bolt 6113, preventing the first protective device 61 from falling off due to unstable installation.

[0046] In some embodiments, such as Figure 4 As shown, the base 611 is provided with a mounting hole 6112, and the outer wall of the quick connector female head 3 is provided with a boss 31 corresponding to the mounting hole 6112. The locking bolt 6113 is provided on the outer wall of the base 611 and communicates with the mounting hole 6112. The base 611 is sleeved on the boss 31 through the mounting hole 6112 and fixed by the locking bolt 6113.

[0047] Specifically, the base 611 is fitted onto the quick connector female 3. Therefore, the base 611 has a mounting hole 6112, the shape of which corresponds to the fitting position on the quick connector female 3. For example, the outer wall of the quick connector female 3 has a boss 31, which is hexagonal in shape, and the mounting hole 6112 on the base 611 is also hexagonal. The boss 31 can also be circular, prismatic, rectangular, etc., and is not specifically limited in this utility model. In this utility model, a hexagonal shape is used as an example. The side wall of the base 611 has a threaded hole for installing a locking bolt 6113. The threaded hole communicates with the mounting hole 6112, and the locking bolt 6113 is screwed into the threaded hole and extends into the mounting hole 6112. After the base 611 is fitted onto the boss 31, the locking bolt 6113 is adjusted so that the end of the locking bolt 6113 abuts against the boss 31, thereby fixing the base 611 to the quick connector female head 3.

[0048] In some embodiments, such as Figure 4 As shown, a pull rope 613 is provided on the base 611, and the other end of the pull rope 613 is connected to the side wall of the protective cover 612.

[0049] Specifically, a pull cord 613 is provided on the side wall of the base 611. The pull cord 613 can be an elastic cord or a linen rope. The other end of the pull cord 613 is connected to the protective cover 612, either to the side wall of the protective cover 612 or to the end of the protective cover 612. By connecting the base 611 and the protective cover 612 together through the pull cord 613, when the first protective device 61 is opened, the protective cover 612 is unscrewed from the base 611. The pull cord 613 prevents the protective cover 612 from being left unattended or lost.

[0050] In some embodiments, such as Figure 5 and Figure 6 As shown, the protection device 6 is a second protection device 62. The second protection device 62 includes a protection barrel 621 and an end cap 622. The end cap 622 is connected to the end of the protection barrel 621 in a flip-top manner. The protection barrel 621 is sleeved on the outer wall of the quick connector female head 3 via one end away from the end cap 622 and is fixed by a locking bolt 6113.

[0051] Specifically, in this embodiment, the protective cover device employs a second protective device 62, which includes a protective barrel 621 and an end cap 622. The end cap 622 is flip-topped at one end of the protective barrel 621. The protective barrel 621 is fitted onto the outer wall of the quick connector female 3 and secured with locking bolts 6113. After the protective barrel 621 is fitted onto the outer wall of the quick connector female 3 and the end cap 622 is placed on top, the second protective device 62 seals the quick connector female 3, thereby protecting it and preventing corrosion and dirt buildup caused by prolonged exposure. Its base 611 is fixed to the outer wall of the quick connector female 3 with locking bolts 6113, preventing the first protective device 61 from falling off due to instability.

[0052] In some embodiments, such as Figure 5 and Figure 6 As shown, the protective barrel 621 has a mounting part 6211 at one end away from the end cap 622. The locking bolt 6113 is provided on the outer wall of the protective barrel 621 and communicates with the mounting part 6211. The quick connector female head 3 has a boss 31 corresponding to the mounting part 6211. The protective barrel 621 is sleeved on the outer wall of the boss 31 through the mounting part 6211 and fixed by the locking bolt 6113.

[0053] Specifically, to ensure stable installation of the protective bucket 621 and the quick connector female head 3, a mounting part 6211 is provided at the end of the protective bucket 621 away from the end cover 622. The mounting part 6211 is hexagonal in shape. The quick connector female head 3 has a corresponding boss 31, also hexagonal in shape. Thus, the mounting part 6211 of the protective bucket 621 fits onto the boss 31, preventing displacement of the protective bucket 621 during installation. A threaded hole is provided on the outer wall of the protective bucket 621, communicating with the mounting part 6211. A locking bolt 6113 is installed in the threaded hole, extending into the mounting part 6211. After the mounting part 6211 is fitted onto the boss 31, adjusting the locking bolt 6113 allows its end to press against the boss 31, thereby fixing the protective bucket 621 and the quick connector female head 3.

[0054] In some embodiments, such as Figure 6 As shown, the end cap 622 is provided with a sealing ring 6221 on the side facing the protective barrel 621.

[0055] Specifically, the sealing ring 6221 is made of rubber. After the end cap 622 is put on, the sealing ring 6221 and the protective barrel 621 are fastened together, thereby fastening the end cap 622 onto the protective barrel 621.

[0056] In some embodiments, such as Figure 6As shown, the diameter of the end cap 622 is larger than the diameter of the protective barrel 621.

[0057] Specifically, when the diameter of the end cap 622 is larger than the diameter of the protective barrel 621, the end cap 622 forms a protruding edge after being placed on the protective barrel 621. The end cap 622 can be removed from the protective barrel 621 through the protruding edge, making it easier to open the end cap 622.

[0058] In some embodiments, such as Figure 6 As shown, the protective barrel 621 has a slot 6212 at one end with an end cap 622.

[0059] Specifically, after the end cap 622 is placed on the protective barrel 621, the end cap 622 can be opened through the slot 6212, which allows fingers or tools to enter, thus facilitating the application of pushing force to the end cap 622 to remove it from the protective barrel 621.

[0060] The implementation process of this utility model is as follows:

[0061] Example 1

When the main pipe 11 is working normally, the second switch valve on the branch pipe 12 is closed, and the water pressure of the main pipe 11 is obtained from the pressure gauge 2. When it is necessary to test the pressure gauge 2, the first switch valve 5 is closed, the second switch valve is opened, the protective cover 612 of the protection device 6 is unscrewed from the base 611, and then the quick connector male head is connected to the quick connector female head 3. The quick connector male head is connected to the testing equipment through the pipeline. That is, the testing equipment is connected to the pressure gauge 2 through the quick connector, and the pressure gauge 2 is calibrated by the testing equipment. After the calibration is completed, the quick connector male head is removed, and the protective cover 612 is screwed onto the base 611. The protective cover 612 protects the quick connector female head 3.

When the main pipeline 11 is working normally, the first pipe 131 and the second pipe 132 of the three-way valve are adjusted to be in passage, and the water pressure of the main pipeline 11 is obtained by the pressure gauge 2. When it is necessary to test the pressure gauge 2, the second pipe 132 of the three-way valve and the branch pipe 12 are adjusted to be in passage, the first pipe 131 is closed, the end cap 622 of the protection device 6 is flipped open on the protection tank 621, and then the quick connector male head is connected to the quick connector female head 3. The quick connector male head is connected to the testing equipment through the pipeline. That is, the testing equipment is connected to the pressure gauge 2 through the quick connector, and the pressure gauge 2 is calibrated by the testing equipment. After the calibration is completed, the quick connector male head is removed, and the end cap 622 is placed on the protection tank 621. The protection tank 621 and the end cap 622 protect the quick connector female head 3.
