In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0023] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "setting" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] like Figure 1 As shown, this embodiment provides a gas pipeline pressure detector with an alarm structure, including a gas pressure detector body 1, a detector interface 11 of the gas pressure detector body 1 is connected to a detection container 13 through a first connecting pipe 12, an input interface 131 of the detection container 13 is connected to a connection interface 15 through a second connecting pipe 17, and the connection interface 15 is used to connect to a gas pipeline interface;

[0025] A detection device is arranged in the detection container 13 , and an alarm device 18 is arranged on the surface of the detection container 13 . The alarm device 18 is signal-connected to the detection device.

[0026] During detection, the connection interface 15 is connected to the interface of the gas pipeline, and the gas in the gas pipeline enters the detection container 13 and the gas pressure detector body 1 through the second connecting pipe 17. The gas pressure detector body 1 and the detection device in the detection container 13 detect the gas pressure, and the gas pressure detector body 1 displays the gas pressure value, while the detection device in the detection container 13 can recheck the detection result of the gas pressure detector body 1, thereby ensuring the detection reliability of the detector. Furthermore, the threshold of the alarm device 18 is set in advance. When the detected pressure exceeds the preset threshold, the alarm device 18 generates an indication function, thereby achieving a warning effect.

[0027] like Figure 2 As shown, the detection device includes an air pressure sensor 133 fixed inside the detection container 13, the outer side of the air pressure sensor 133 is covered with a protective shell 134, and the probe of the air pressure sensor 133 penetrates the protective shell 134 and extends into the cavity of the detection container 13. It should be noted that the first connecting pipe 12 is connected to the output interface 132 of the detection container 13, and the air pressure sensor 133 detects the air pressure in the detection container 13, and sends an alarm signal to the alarm device 18 when it exceeds the threshold.

[0028] Optionally, the alarm device 18 includes an indicator light, a buzzer and a display. In this embodiment, the alarm device 18 uses an indicator light. When the result detected by the air pressure sensor 133 exceeds the threshold, the air pressure sensor 133 flashes to warn the operator. Of course, a buzzer can also be used to generate a sound alarm.

[0029] Furthermore, the first connecting pipe 12 and the second connecting pipe 17 are respectively provided with a second manual valve 16 and a first manual valve 14. When the second manual valve 16 and the first manual valve 14 are in a closed state, the detection container 13 forms a sealed container. At the same time, the second manual valve 16 can be closed when the gas pressure detector body 1 is not required for detection or in the subsequent ignition process to avoid damage to the gas pressure detector body 1. However, this method has a small amount of gas overflow.

[0030] A gas processing interface 19 is provided on the detection container 13, and the gas processing interface 19 includes a pressure relief pipe 192 fixed on the detection container 13 and connected to the cavity of the detection container 13, an electronic igniter 193 is provided in the pressure relief pipe 192, and a sealing cover 191 is detachably connected to the pipe mouth of the pressure relief pipe 192, and the sealing cover 191 closes the opening of the pressure relief pipe 192.

[0031] After the detection is completed, since there is natural gas in the pipeline of the gas pressure detector body 1, directly disassembling the connecting interface 15 from the gas pipeline may cause gas overflow and harm the operator. Before removing the connecting interface 15, the first manual valve 14 is closed, the sealing cover 191 is unscrewed, and the electronic lighter 193 is ignited at the same time, so that the gas in the gas pressure detector body 1 and the pipeline is ignited through the pressure relief pipe 192 and then overflows to avoid harm to the human body.

[0032] In this embodiment, the outer wall of the pressure relief pipe 192 is processed with threads, and the sealing cover 191 is connected to the pressure relief pipe 192 by threads. The threaded connection between the sealing cover 191 and the pressure relief pipe 192 can ensure that the detection container 13 is in a sealed state on the one hand, and can be easily disassembled and assembled on the other hand.

[0033] In this embodiment, the detection container 13, the first connecting pipe 12, the second connecting pipe 17 and the gas processing interface 19 are all made of fireproof materials. Since the combustion of gas generates heat, in order to prevent the heat from affecting the detection container 13, the first connecting pipe 12 and the second connecting pipe 17, fireproof materials are used. For example, the fireproof material can be selected from fireproof plastics, which have flame retardants inside and have good fireproof properties.

[0034] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
