[0003] Pressure measuring instruments are a common type of industrial instrument, often used to measure pressure in pressurized pipelines. Their proper operation plays a vital role in ensuring production safety. Existing pressure measuring instruments are widely used in industrial production and often require integration with other accessories to form a stable and safe measuring instrument system. A common method of use involves first opening an opening in the pipeline, then installing a shutoff valve, a condensate trap, and a pressure gauge on the condensate trap. This measuring instrument system effectively mitigates the impact of high-pressure fluid on the interior of the pressure instrument, ensuring the instrument's service life. However, in actual installation, the considerable height of the condensate trap requires a large installation space, which places considerable demands on plant layout. Furthermore, existing pressure instruments often lack a simple and effective pressure relief method during disassembly, replacement, and maintenance. The common practice is for operators to slowly loosen bolts, gradually releasing pressure during the process. This places high demands on operator skill and poses certain safety risks during replacement and maintenance.
[0004] Therefore, a measuring instrument system that can effectively reduce the installation space occupied during use and at the same time can achieve multiple functions such as buffering, corrosion protection and pressure relief is a technical problem that needs to be solved.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field fall within the scope of protection of the present invention.
[0024] Embodiments of the present utility model:
[0025] like Figure 1-4 As shown, in this embodiment, a stop valve 2 is installed on the pressure pipe 1, which is detachably connected to a connector 3 on the stop valve 2 and is detachably connected to a pressure meter 4 above the connector 3.
[0026] In this embodiment, the connector 3 is provided with an upper half 31 and a lower half 32, which are fixedly connected by a connecting portion 33. In this embodiment, the upper half 31 and the lower half 32 are fixedly and sealedly connected to the connecting portion 33 by welding.
[0027] In this embodiment, a pressure gauge mating portion 311 is provided in the upper portion 31, and the pressure gauge mating portion 311 is an internal thread groove that cooperates with the threaded connection portion 33 below the pressure gauge 4; and a first connecting portion 312 is provided in the upper portion 31, and a second connecting portion 331 is provided in the connection portion 33, and the first connecting portion 312 is connected to the second connecting portion 331.
[0028] In this embodiment, a cavity 321 is provided in the lower half 32, and the upper part of the cavity 321 is connected to the second connecting portion 331. Baffles 322 are arranged in an alternating manner in the cavity 321. Specifically, in this embodiment, the cross-section of the cavity 321 is circular, and the shape of the baffle 322 is the remaining shape after a circle is cut off. The baffle 322 and the cavity 321 are fixedly connected by welding.
[0029] In this embodiment, a stop valve fitting portion 35 is provided below the lower half 32 , the stop valve fitting portion 35 is threadedly fitted with the stop valve 2 , a third connecting portion 351 is provided in the stop valve fitting portion 35 , and the third connecting portion 351 is connected to the cavity 321 .
[0030] In another embodiment of the present invention, a pressure relief bolt 34 is installed in the upper part 31, wherein a threaded hole 313 is opened on one side of the first connecting part 312, which is connected to the pressure relief bolt 34 through the threaded hole 313, and a hexagon socket bolt head 341 is provided in the pressure relief bolt 34, which is connected to the screw rod 342, and a reverse "L"-shaped through hole 343 is provided in the screw rod 342 in the direction from the head of the screw rod 342 to the hexagon socket bolt head 341. When the pressure relief bolt 34 is turned, the through hole 343 is connected to the atmosphere to realize the pressure relief process; the through hole 343 can be processed by drilling.
[0031] The principle of this utility model is:
[0032] When the present invention is in use, the stop valve 2 is connected to the opening of the pressure pipe 1. During the process, the stop valve 2 is an existing standard component, and its structure is not described in detail.
[0033] Then, connect the connecting piece 3 to the stop valve 2 and install the pressure meter 4 on the connecting piece 3. When in use, open the valve on the stop valve 2, so that the pressure meter 4 is connected to the pressure pipe 1, and the pressure in the pressure pipe 1 can be measured. The pressure meter 4 is an existing mature equipment, and its structural principle will not be repeated here.
[0034] During the use of the present invention, when the pressure gauge 4 is installed and the valve of the stop valve 2 is opened, the baffles 322 alternately arranged in the connecting piece 3 can reduce the impact of the high-pressure fluid in the pressure pipe 1 on the inside of the pressure gauge 4, thereby effectively ensuring the stability and service life of the pressure gauge 4. In addition, for some corrosive fluid materials, the present invention can also play a good barrier role. For example, corrosive liquids will not splash into the inside of the pressure gauge 4 due to the setting of the baffle 322. For corrosive volatile gases, the setting of the baffle 322 can also play a condensation role, and can also effectively prevent a large amount of corrosive materials from entering the inside of the pressure gauge 4, which plays a positive and effective role in ensuring the stable use of the instrument.
[0035] In addition, the present invention adopts a connector 3, which occupies a small space. Compared with the existing condensation bend, it can greatly reduce the space required for installation and is more convenient for use in actual production.
[0036] At the same time, when the present invention is used, when the pressure instrument 4 needs to be replaced or repaired, it is only necessary to close the valve of the stop valve 2 and loosen the pressure relief bolt 34, which is convenient for replacement and also avoids the safety hazards caused by the high-pressure environment in the connecting part 3. In addition, in the present invention, the pressure relief bolt 34 is used for pressure relief, and the bolt head of the pressure relief bolt 34 adopts an inner hexagonal design, which avoids accidental touch during daily use and can ensure stable installation and use of the instrument.
