[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0020] In the description of the present invention, it should be noted that the terms "vertical", "up", "down", "horizontal", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] like Figure 1-4As shown, a gas delivery pipeline safety valve of the utility model comprises: a valve body 1; a filter assembly 2, one end of the filter assembly 2 is connected to the valve body 1 through a connecting pipe 3, and the other end of the filter assembly 2 is connected to an air inlet pipe 4; a pressure relief assembly 5, the pressure relief assembly 5 is connected to the valve body 1, and the pressure relief assembly 5 is connected to an exhaust pipe 7 through an air guide pipe 6; an alarm assembly 8, and the alarm assembly 8 is arranged on the pressure relief assembly 5; the filter assembly 2 comprises a filter tube 201, a filter plate 202 and an activated carbon plate 203 are arranged inside the filter tube 201, mounting tubes 204 are arranged at both ends of the filter tube 201, the mounting tube 204 is detachably connected to the connecting tube 3 and the air inlet pipe 4, and a sealing rubber pad 205 is arranged inside the mounting tube 204.

[0023] In this embodiment, the gas enters the valve body 1 through the filter assembly 2 via the air inlet pipe 4. When the gas passes through the filter tube 201, the filter plate 202 in the filter tube 201 can filter out impurities in the gas before the gas enters the interior of the valve body 1, thereby preventing impurities from causing blockage in the valve and affecting the use of the safety valve. The activated carbon plate 203 can effectively adsorb harmful substances and odorous substances in the gas. Through the high-efficiency filtering ability of the activated carbon plate 203, it can extend the service life of the valve body 1 and further prevent harmful substances and particles from entering the interior of the valve body 1. The activated carbon plate 203 can reduce the pollution and wear of the valve body 1, thereby extending the operating time and efficiency of the entire safety valve system.

[0024] The installation tube 204 facilitates the disassembly of the filter tube 201 and the replacement of the filter tube 201 , and the sealing rubber pad 205 can enhance the sealing performance at both ends of the filter tube 201 .

[0025] like Figure 1 and Figure 2 As shown, specifically, a partition plate 9 is provided inside the valve body 1, a through hole 10 is opened on the partition plate 9, an electromagnet 11 is provided on one side of the partition plate 9, a mounting frame 12 is provided on the other side of the partition plate 9, a first compression spring 13 is provided inside the mounting frame 12, the first compression spring 13 is connected to one end of a first connecting rod 14, and the other end of the first connecting rod 14 is connected to a first sealing block 15; when the electromagnet 11 works, the electromagnet 11 will magnetically attract the first sealing block 15 to move, at which time the through hole on the partition plate 9 is opened, and the gas can be discharged normally from the valve body 1 to complete the transportation.

[0026] like Figure 2 and Figure 4As shown, specifically, the pressure relief assembly 5 includes a pressure relief pipe 51, a second compression spring 52 is arranged inside the pressure relief pipe 51, the second compression spring 52 is connected to the second connecting rod 53 at the bottom, the second connecting rod 53 is connected to the second sealing block 16 at the bottom, the pressure relief pipe 51 is connected to the valve body 1, a first pressure relief hole 54 is opened on the valve body 1, and a second pressure relief hole 55 is opened on the pressure relief pipe 51; when the gas pressure inside the valve body 1 is too high due to factors such as valve failure or improper user operation, the gas pressure inside the valve body 1 exceeds the elastic force of the second compression spring 52, and the gas pressure will push the second sealing block 16 and the second connecting rod 53 to rise. At this time, the gas will enter the air guide pipe 6 through the first pressure relief hole 54 and the second pressure relief hole 55, and be discharged to the pressure relief container through the exhaust pipe 7, thereby completing the pressure relief, and the use safety is relatively high.

[0027] like Figure 2 and Figure 4 As shown, specifically, the alarm component 8 includes an alarm 81, a first contact 82 and a second contact 83. The alarm 81 is electrically connected to the first contact 82 and the second contact 83. The alarm 81 is connected to the pressure relief pipe 51, the first contact 82 is connected to the inner wall of the pressure relief pipe 51, and the second contact 83 is arranged on the second connecting rod 53; when the second connecting rod 53 moves upward, it will drive the second contact 83 to move upward and contact and conduct with the first contact 82. The alarm 81 is electrically connected between the two contacts, so that the alarm 81 sounds an alarm while the pressure is being relieved, which is convenient for the staff to inspect and protect the pipeline.

[0028] like Figure 1 and Figure 2 As shown, specifically, an air outlet pipe 17 is provided at one end of the valve body 1, and a knurled nut 18 is provided on both the air outlet pipe 17 and the air inlet pipe 4; the knurled nut 18 can provide better sealing when the safety valve is installed. At the same time, the handle provided on the surface of the knurled nut 18 can facilitate the staff to use their hands to leverage when installing the safety valve, so that the safety valve and the pipeline can be installed and fixed without the aid of other tools, and the operation is convenient and quick.

[0029] like Figure 1 and Figure 2 As shown, specifically, a plurality of flow equalizing plates 19 are arranged inside the valve body 1; the plurality of flow equalizing plates 19 can help the fluid to be more evenly distributed inside the valve body 1, and during the gas flow process, the eddy current or turbulence caused by the uneven flow can be reduced or eliminated by the arranged flow equalizing plates 19, thereby ensuring the stability and uniformity of the fluid when passing through the valve 1.

[0030] Working principle: The gas enters the valve body 1 through the filter assembly 2 via the air inlet pipe 4. When the gas passes through the filter tube 201, the filter plate 202 in the filter tube 201 can filter out impurities in the gas before the gas enters the valve body 1, thereby preventing impurities from clogging the valve and affecting the use of the safety valve. The activated carbon plate 203 can effectively adsorb harmful substances and odorous substances in the gas. Through the high-efficiency filtering ability of the activated carbon plate 203, it can extend the service life of the valve body 1 and further prevent harmful substances and particles from entering the valve body 1. The activated carbon plate 203 can reduce the pollution and wear of the valve body 1, thereby extending the operating time and efficiency of the entire safety valve system.
