Description

Technical Field

[0001] This utility model relates to the field of ultra-high pressure gauge technology, and in particular to an ultra-high pressure gauge that uses high pulse and high frequency. Background Technology

[0002] Ultra-high pressure gauges are pressure measuring devices with a measurement range typically above 100 MPa (1000 Bar), capable of accurately monitoring pressure values ​​under extreme high-pressure environments. They are classified as special pressure instruments and must meet requirements for high strength, high stability, and high safety.

[0003] When pressure gauges are used, especially traditional ultra-high pressure gauges, purely mechanical pressure gauges are typically used to ensure stable operation and suitability for harsh environments. However, in some applications, such as ultra-high pressure waterjet cutting machines, aircraft hydraulic systems, high-frequency vibration tables, and hydraulic impact test benches, the internal pressure may rise rapidly from a low level to a high level. This type of use can cause damage to purely mechanical ultra-high pressure gauges. In particular, rapid pressure changes can lead to malfunctions in the internal transmission mechanism of mechanical pressure gauges, and the accuracy of the gauges decreases with repeated use. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies by proposing an ultra-high pressure gauge that operates with high pulse and high frequency. To achieve the above objective, this invention adopts the following technical solution:

[0005] A high-pressure gauge for high-pulse, high-frequency applications includes: a measuring connection water pipe, a protective base, and a spiral Bourdon tube. The head of the spiral Bourdon tube is connected to the tail of the measuring connection water pipe, and the tail of the spiral Bourdon tube is sealed. The protective base is fixedly installed on the outside of the measuring connection water pipe. A detection structure is installed on the outer wall of the spiral Bourdon tube, and a display structure is installed inside the protective base. The detection structure includes: a head turntable, a tail turntable, a pull-string displacement sensor, and a tail connecting post. The head turntable is installed at the tail of the measuring connection water pipe, the tail turntable is installed at the tail of the spiral Bourdon tube, the pull-string displacement sensor is installed on the outer wall of the head turntable, and the tail connecting post is installed on the outer wall of the tail turntable. The pull-up end of the pull-string displacement sensor is fixedly connected to the tail connecting post.

[0006] The present invention is further configured such that the display structure includes: a display panel, a processor, and a digital display; the display panel is fixedly installed inside the protective base by bolts, the display panel has a slot, the digital display is installed in the slot of the display panel, and the processor is installed on the back of the display panel.

[0009] The present invention is further provided that a protective panel is installed on the front of the protective base.

[0010] The present invention is further provided with a low battery warning light installed on the front of the display panel.

[0011] The beneficial effects of this utility model are as follows: This utility model improves the existing ultra-high pressure gauge by using a traditional spiral Bourdon tube to drive a pull rope displacement sensor for measurement, thereby obtaining the pressure parameters. To a certain extent, it retains the mechanical pressure measurement mechanism, replacing the mechanical mechanism that would be damaged under rapid pressure changes with a sensing structure. This ensures both the stable operation of the ultra-high pressure gauge and its accuracy during long-term operation. Attached Figure Description

[0021] Reference Figure 1-4 A high-pulse, high-frequency ultra-high pressure gauge includes: a measuring connection water pipe 1, a protective base 2, and a spiral Bourdon tube 3. The head of the spiral Bourdon tube 3 is connected to the tail of the measuring connection water pipe 1, and the tail of the spiral Bourdon tube 3 is sealed. The protective base 2 is fixedly installed on the outside of the measuring connection water pipe 1. A detection structure is installed on the outer wall of the spiral Bourdon tube 3, and a display structure is installed inside the protective base 2. The detection structure includes: a head turntable 4, a tail turntable 5, a pull rope displacement sensor 6, and a tail connecting post 7. The head turntable 4 is installed on... The measuring connection is made at the tail end of the water pipe 1. The tail turntable 5 is installed at the tail end of the spiral Bourdon tube 3. The pull rope displacement sensor 6 is installed on the outer wall of the head turntable 4. The tail connecting post 7 is installed on the outer wall of the tail turntable 5. The pull end of the pull rope displacement sensor 6 and the tail connecting post 7 are fixedly connected. The battery 11 is installed on the inner side of the protective base 2. The back of the protective base 2 is provided with a clearance hole. The charging interface 12 is installed in the clearance hole of the protective base 2. The charging interface 12 and the battery 11 are connected by a charging cable. The front of the protective base 2 is provided with a protective panel 13.

[0022] As a preferred embodiment, the display structure further includes: a display panel 8, a processor 9, and a digital display 10; the display panel 8 is fixedly installed inside the protective base 2 by bolts, the display panel 8 has a slot, the digital display 10 is installed in the slot of the display panel 8, the processor 9 is installed on the back of the display panel 8, and a low battery warning light 14 is installed on the front of the display panel 8.

[0023] Working principle: When using this invention, the operator first installs the measuring connection water pipe 1 into the pipe to be tested via threads. Then, the operator connects an external AC power supply to the charging interface 12 to charge the battery 11. Once charging is complete, the low battery warning light 14 goes out. Then, during normal use, the test water source enters the spiral Bourdon tube 3 through the measuring connection water pipe 1. When the water pressure increases, the water enters the spiral Bourdon tube 3 under pressure. The spiral Bourdon tube 3 is subjected to water pressure... The overall radius of the spiral Bourdon tube 3 increases, and the tail of the spiral Bourdon tube 3 drives the tail connecting column 7 to move outward. The tail connecting column 7 pulls the pull rope of the pull rope displacement sensor 6 to move outward. At this time, the extension of the pull rope of the pull rope displacement sensor 6 is transmitted to the processor 9 through an electrical signal. The processor 9 calculates the water pressure at this time and displays it through the digital display 10. It should be noted that the spiral Bourdon tube 3 is made of stainless steel, so the spiral Bourdon tube 3 has better rigidity and can still ensure measurement accuracy under water pressure with high pulse changes and high frequency changes.
