Technical Field

[0001] The utility model relates to the technical field of gas monitoring, in particular to a gas safety monitoring device. Background Art

[0002] The gas pressure gauge is an instrument used to monitor the gas pressure. Its working principle is based on the principle of pressure sensor, which converts the pressure into an electrical signal, which is then processed by the processing circuit and finally displayed in the form of numbers or pointers.

[0003] According to the public announcement number: CN217901147U, a gas pipeline monitoring device that is easy to install is disclosed. This technology discloses technical solutions such as "the positioning block is passed through the positioning slot, and the positioning block is clamped into the clamping slot of the fixing mechanism, so that the upper plate and the lower plate can be fixed", which has technical effects such as "realizing the rapid installation of the gas pressure detector without the need for auxiliary installation tools, which can improve the installation efficiency";

[0004] Although the above scheme can realize quick installation of the gas pressure detector, since the connection between the gas pressure detector and the pipeline is exposed, it is easy to age after long-term use, resulting in gas leakage; and a slight loose seal makes it impossible for the staff to discover it in the first time and perform timely maintenance. Utility Model Content

[0005] In view of the deficiencies of the prior art, the utility model provides a gas safety monitoring device, which has the characteristic of enabling workers to intuitively detect whether there is gas leakage at the connection between the gas pressure gauge and the connecting pipe through a leakage monitoring mechanism.

[0006] To achieve the above purpose, the utility model is implemented through the following technical solutions: a gas safety monitoring device, including a connecting pipe, the upper end of the connecting pipe is connected and fixed with a mounting seat, a gas pressure gauge is installed on the mounting seat, and the gas pressure gauge is provided with a mounting head and penetrates and inserts into the interior of the mounting seat, the mounting head is provided with a fixing mechanism and is used for mounting and fixing the gas pressure gauge and the connecting pipe, the mounting head is provided with a leakage monitoring mechanism and is used for leakage monitoring between the gas pressure gauge and the connecting pipe, and the leakage monitoring mechanism includes:

[0007] The sealing assembly comprises a sealing cylinder sleeve mounted on the mounting head;

[0008] The leakage monitoring component comprises an extension tube connected to a fixed end of a sealing tube, a spring is installed inside the extension tube, and a rubber plug is installed at one end of the spring, a leakage port is connected to a fixed lower end of the extension tube, and an air bag is installed on the leakage port.

[0014] Beneficial Effects

[0015] The utility model provides a gas safety monitoring device. Compared with the prior art, it has the following beneficial effects:

[0016] (1) After the gas pressure gauge is installed on the connecting pipe and a closed space is formed by the sealing assembly, when gas leakage occurs between the gas pressure gauge and the connecting pipe, the gas will push the rubber plug to squeeze the spring, and the gas will enter the extension tube. Through the continuous leakage of gas, the gas will enter the airbag through the leak port, causing it to expand until it breaks, so that the staff can intuitively detect whether there is gas leakage at the connection between the gas pressure gauge and the connecting pipe.

[0017] (2) When the gas pressure gauge is installed on the connecting pipe, the mounting head on the gas pressure gauge is inserted into the mounting seat on the connecting pipe, and the sealing cylinder is driven by rotating the nut. The sealing cylinder pushes the clamping head on the sleeve to move downward, so that the clamping head squeezes the clamping head to flip inward, and the lower end of the clamping head buckles the mounting seat, so that the gas pressure gauge can be quickly disassembled and assembled with the connecting pipe through the fixing assembly, and is firmly fixed after installation.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-4 The utility model provides a technical solution for a gas safety monitoring device: a gas safety monitoring device, comprising a connecting pipe 1, the upper end of the connecting pipe 1 is connected and fixed with a mounting seat 2, a gas pressure gauge 3 is mounted on the mounting seat 2, and a mounting head 6 is provided on the gas pressure gauge 3 and penetrates and inserts into the interior of the mounting seat 2, the mounting head 6 is provided with a fixing mechanism 4 and is used for mounting and fixing the gas pressure gauge 3 and the connecting pipe 1, the mounting head 6 is provided with a leakage monitoring mechanism 5 and is used for leakage monitoring between the gas pressure gauge 3 and the connecting pipe 1, and the leakage monitoring mechanism 5 includes:

[0025] The sealing assembly 51 includes a sealing cylinder 511 sleeved and mounted on the mounting head 6;

[0026] The leakage monitoring assembly 52 includes a sealing tube 511 connected to a fixed extension tube 521 at one end, a spring 522 is installed inside the extension tube 521, and a rubber plug 523 is installed at one end of the spring 522. The lower end of the extension tube 521 is connected to a fixed air leakage port 524, and an air bag 525 is installed on the air leakage port 524.

[0027] In this embodiment, when the gas pressure gauge 3 is installed on the connecting pipe 1 and a closed space is formed by the sealing assembly 51, when gas leakage occurs between the gas pressure gauge 3 and the connecting pipe 1, the gas will push the rubber plug 523 to squeeze the spring 522, and the gas will enter the extension tube 521. Through the continuous leakage of gas, the gas will enter the air bag 525 through the leakage port 524, causing it to expand until it breaks, so that the staff can intuitively perceive whether the gas is leaking at the connection between the gas pressure gauge 3 and the connecting pipe 1.

[0028] Specifically, the sealing assembly 51 further includes a nut 512 threadedly mounted on the outer wall of the mounting head 6 , and the nut 512 is located at the upper end of the outer wall of the sealing cylinder 511 .

[0029] In this embodiment, after the gas pressure gauge 3 is installed on the connecting pipe 1, the sealing cylinder 511 and the mounting seat 2 can be pushed to close by rotating and tightening the nut 512, and the sealing after closing is improved by the second sealing ring 513, so that after the gas pressure gauge 3 is installed on the connecting pipe 1, a closed space is formed inside the sealing cylinder 511.

[0030] Specifically, the fixing mechanism 4 includes three circumferentially distributed clamping heads 411 pivotally connected to the outer wall of the lower end of the mounting head 6 , a sleeve 412 sleeved and mounted on the mounting head 6 , and a clamping head 413 fixed to the outer wall of the lower end of the sleeve 412 .

[0031] In this embodiment, when the gas pressure gauge 3 is installed on the connecting pipe 1, the mounting head 6 on the gas pressure gauge 3 is inserted into the mounting seat 2 on the connecting pipe 1, and then the sealing tube 511 is driven by rotating the nut 512. The sealing tube 511 pushes the clamping head 413 on the sleeve 412 to move downward, so that the clamping head 413 squeezes the clamping head 411 to flip inward, and the lower end of the clamping head 411 buckles the mounting seat 2, so that the gas pressure gauge 3 can be quickly disassembled and assembled with the connecting pipe 1 through the fixing component 41, and is firmly fixed after installation.

[0032] Working principle and use process of the utility model: First, when the gas pressure gauge 3 is installed on the connecting pipe 1, the mounting head 6 on the gas pressure gauge 3 is inserted into the mounting seat 2 on the connecting pipe 1, and then the sealing cylinder 511 is driven by rotating the nut 512, and the sealing cylinder 511 pushes the clamping head 413 on the sleeve 412 to move downward, so that the clamping head 413 squeezes the clamping head 411 to turn inward, and the lower end of the clamping head 411 buckles the mounting seat 2, so that the gas pressure gauge 3 can be quickly disassembled and assembled with the connecting pipe 1 through the fixing component 41, and is firmly fixed after installation;

[0033] At the same time, when the nut 512 drives the sealing cylinder 511 to move downward, the sealing cylinder 511 and the mounting seat 2 are closed, and the second sealing ring 513 is used to improve the sealing after closing, so that after the gas pressure gauge 3 is installed on the connecting pipe 1, a closed space is formed inside the sealing cylinder 511; when a gas leak occurs between the gas pressure gauge 3 and the connecting pipe 1, the gas will push the rubber plug 523 to squeeze the spring 522, and the gas will enter the extension cylinder 521, and through the continuous leakage of gas, the gas will enter the air bag 525 through the leakage port 524, causing it to expand until it breaks, so that the staff can intuitively perceive whether the gas is leaking at the connection between the gas pressure gauge 3 and the connecting pipe 1.
