[0036] like Figure 1 As shown, the utility model provides a safe workshop gas dispersing system, comprising:

[0037] The main gas inlet pipe 17 is connected to the sixth gas pipe 20 through the main gas valve 14;

[0038] The sixth gas pipeline 20 is connected to the first gas pipeline 9;

[0039] The first gas pipeline 9 is provided with a first gas valve 8, a first filter 5, and a first pressure regulating valve group 4 in sequence;

[0040] The outlet of the first gas pipeline 9 is connected to the first boiler 1 through the second gas pipeline 2;

[0041] A first relief pipe 24, one end of which is connected to the sixth gas pipeline 20, and the other end of which is connected to the main relief pipe 25. The first relief pipe 24 is provided with a first relief valve 19;

[0042] The second gas pipeline 2 is connected to the main discharge pipe 25 through the second discharge pipe 11, and the second discharge pipe 11 is provided with a second discharge valve 3;

[0043] The first gas pipeline 9 between the first gas valve 8 and the first filter 5 is connected to the main relief pipe 25 through the third relief pipe 10 , and the third relief pipe 10 is provided with a third relief valve 6 .

[0044] Furthermore, the safe workshop gas release system further includes a third gas pipeline 30, and the sixth gas pipeline 20 is also connected to the third gas pipeline 30;

[0045] The third gas pipeline 30 is provided with a second gas valve 28, a second filter 32, and a second pressure regulating valve group 33 in sequence;

[0046] The outlet of the third gas pipeline 30 is connected to the second boiler 37 through the fourth gas pipeline 35;

[0047] The fourth gas pipeline 35 is connected to the main discharge pipe 25 through the fourth discharge pipe 31, and the fourth discharge pipe 31 is provided with a fourth discharge valve 34;

[0048] The third gas pipeline 30 between the second gas valve 28 and the second filter 32 is connected to the main relief pipe 25 through the fifth relief pipe 27 . The fifth relief pipe 27 is provided with a fifth relief valve 29 .

[0049] Specifically:

[0050] After being reduced in pressure at the plant gas station 12, municipal gas flows through the main intake pipe 17 and the main gas valve 14 into the boiler room 36. Within the boiler room 36, the gas flows through the main intake pipe 17 into the sixth gas pipe 20. The gas then flows through the first gas pipe 9, the first gas valve 8, the fifth gas pipe 7, the first filter 5, the first pressure regulating valve assembly 4, and the second gas pipe 2 into the first boiler 1, thereby providing fuel for combustion in the first boiler 1.

[0051] In detail, the sixth gas pipeline 20 is connected to the first gas pipeline 9 through the seventh gas pipeline 26. The optional sixth gas pipeline 20 and the seventh gas pipeline 26 are integrally formed.

[0052] More specifically, the first gas pipeline 9 is connected to the fifth gas pipeline 7 via the first gas valve 8, and the first gas valve 8 is connected to the first filter 5 via the fifth gas pipeline 7. Optionally, the first gas pipeline 9 and the fifth gas pipeline 7 are integrally formed.

[0053] Furthermore, the sixth gas pipeline 20 is also connected to the third gas pipeline 30. After passing through the third gas pipeline 30, the gas passes through the second gas valve 28, the second filter 32, the second pressure regulating valve group 33, and the fourth gas pipeline 35 in sequence to enter the second boiler 37, thereby providing fuel for the second boiler 37 for combustion.

[0054] In detail, the sixth gas pipeline 20 is connected to the third gas pipeline 30 through the seventh gas pipeline 26. The sixth gas pipeline 20 and the seventh gas pipeline 26 are optionally formed in one piece.

[0055] Therefore, gas is provided to multiple boilers for use simultaneously through one gas station 12 and one gas inlet main pipeline 17 .

[0056] If the gas inlet main pipeline 17 needs maintenance, the main gas valve 14 and the first gas valve 8 and the second gas valve 28 of each boiler are closed, and the first relief valve 19 is opened.

[0057] Since one end of the first relief pipe 24 is connected to the sixth gas pipeline 20 and the other end is connected to the main relief pipe 25 , the first relief pipe 24 is provided with a first relief valve 19 .

[0058] At this time, the gas in the air intake main pipeline 17, the sixth gas pipeline 20, the seventh gas pipeline 26 and the first gas pipeline 9 will be discharged to the outside from the gas release port 23 after passing through the first release valve 19, the first release pipe 24, and the main release pipe 25.

[0059] When the first boiler 1 is shut down, it is necessary to repair the burner of the first boiler 1 and the accessories of the first pressure regulating valve group 4 or clean the first gas filter 5.

[0060] Since the second gas pipeline 2 is connected to the main discharge pipe 25 through the second discharge pipe 11, the second discharge pipe 11 is provided with a second discharge valve 3, and the first gas pipeline 9 between the first gas valve 8 and the first filter 5 is connected to the main discharge pipe 25 through the third discharge pipe 10, and the third discharge pipe 10 is provided with a third discharge valve 6.

[0061] Close the first gas valve 8, open the second relief valve 3 and the third relief valve 6, and the residual gas in the second gas pipeline 2, the first pressure regulating valve group 4, the first filter 5, and the fifth gas pipeline 7 passes through the second relief valve 3, the second relief pipe 11 and the third relief valve 6, and then enters the main relief pipe 25 through the third relief pipe 10 and is discharged to the outside from the gas relief port 23. In this way, not only can the gas in the fifth gas pipeline 7, the first filter 5 and other accessories at the front end of the first pressure regulating valve group 4 be released, but even if the first pressure regulating valve group 4 is in the closed state, all the gas in the second gas pipeline 2 and accessories after the first pressure regulating valve group 4 and at the front end of the first boiler 1 can be released, thereby eliminating safety hazards.

[0062] Similarly, when the second boiler 37 is shut down, it is necessary to repair the burner of the second boiler 37 and the accessories of the second pressure regulating valve group 33 or clean the second gas filter 32.

[0063] Since the fourth gas pipeline 35 is connected to the main discharge pipe 25 through the fourth discharge pipe 31, a fourth discharge valve 34 is provided on the fourth discharge pipe 31;

[0064] The third gas pipeline 30 between the second gas valve 28 and the second filter 32 is connected to the main relief pipe 25 through the fifth relief pipe 27 . The fifth relief pipe 27 is provided with a fifth relief valve 29 .

[0065] Close the second gas valve 28, open the fourth relief valve 34 and the fifth relief valve 29, and the residual gas in the fourth gas pipeline 35, the second pressure regulating valve group 33, the second filter 32 and the third gas pipeline 30 enters the main relief pipe 25 through the fourth relief valve 34, the fourth relief pipe 31, the fifth relief valve 29 and the fifth relief pipe 27, and is then discharged to the outside from the gas relief port 23. In this way, not only can the gas in the third gas pipeline 30, the second filter 32 and other accessories in front of the second pressure regulating valve group 33 be released, but even if the second pressure regulating valve group 33 is in the closed state, the gas in the fourth gas pipeline 35 and other accessories behind the second pressure regulating valve group 33 and in front of the second boiler 37 can also be completely released, thereby eliminating safety hazards.

[0066] like Figure 1 As shown, in some optional embodiments, the present invention provides a safe workshop gas release system further including a first gas detection probe 22 , which is arranged at the gas release port 23 of the main release pipe 25 .

[0067] Furthermore, it also includes a first gas alarm 40 , which is arranged in the control room 39 , and the first gas detection probe 22 is connected to the first gas alarm 40 through the first line 38 .

[0068] To prevent equipment maintenance or repairs from occurring before gas has been fully released after a relief valve is opened, a first gas detection probe 22 is installed near the top of the gas relief port 23. The value detected by the first gas detection probe 22 is transmitted via a first line 38 to a first gas alarm 40 installed in the boiler control room 39. The first gas alarm 40 not only sounds an alarm but also allows the gas value at the gas relief port 23 to be monitored. When a relief valve is opened, it is important not only to check that the pressure gauges on each gas pipeline display zero pressure but also to check that the gas value detected by the first gas detection probe 22 is zero or near zero. This ensures safer maintenance of each gas pipeline, accessory, or boiler.

[0069] If the first gas alarm 40 in the control room 39 of the boiler room 36 sounds an alarm when no maintenance is being performed and all relief valves are closed, the operator in the control room 39 can promptly detect any leakage in the relief valve and promptly inspect and replace the relief valve. In particular, if the relief valve is forgotten to be closed after repairing the pipeline or equipment and the corresponding gas valve is opened to supply gas to the boiler equipment, the first gas alarm 40 will remain in the alarm state, thus reminding the operator to promptly close the corresponding relief valve.

[0070] like Figure 1 As shown, in some optional embodiments, the utility model provides a safe workshop gas release system further including a second gas detection probe 21 , which is arranged in the boiler room 36 .

[0071] Furthermore, there are at least two second gas detection probes 21 , and the plurality of second gas detection probes 21 are arranged at intervals in the boiler room 36 .

[0072] Furthermore, a second gas alarm 15 is included, and multiple second gas detection probes 21 are connected to the second gas alarm 15 through a second line 18.

[0073] Furthermore, it also includes an automatic shut-off valve 13 , which is arranged on the air intake main pipe 17 .

[0074] Furthermore, the second gas alarm 15 is controllably connected to the automatic shut-off valve 13 via a third line 16 .

[0075] Specifically:

[0076] Boiler room 36 is also equipped with multiple high-level second gas detection probes 21. When a gas leak occurs in a particular location, such as a boiler burner, a pressure-regulating valve assembly, a filter, or a gas pipeline, the second gas detection probe 21 transmits the gas reading via a second line 18 to a second gas alarm 15. When the gas reading in boiler room 36 reaches the alarm threshold, the second gas alarm 15 not only sounds an audible alarm but also transmits a signal via a third line 16 to an outdoor automatic shut-off valve 13. This automatically closes, halting the gas supply to boiler room 36 and preventing a large gas leak. Only after the gas leak in boiler room 36 has been resolved can the automatic shut-off valve 13 be manually reset on-site, ensuring greater safety and reliability for the boiler room 36 gas system.

[0077] In summary, the present invention not only installs the first relief valve 19 and the first relief pipe 24 on the sixth gas pipeline 20 after the main gas valve 14 on the gas inlet main pipeline 17, but also installs the second relief pipe 11 and the second relief valve 3, as well as the third relief pipe 10 and the third relief valve 6 before and after the first pressure regulating valve group 4 of the first boiler 1. When repairing the burner of the first boiler 1 or the first pressure regulating valve group 4, or cleaning the filter element of the first gas filter 5, the first gas valve 8 at the front end is closed, and the gas in each pipeline and accessory can be discharged to the roof through the main relief pipe 25.

[0078] A first gas detection probe 22 is installed at the gas discharge port 23 of the outdoor main discharge pipe 25. Once the gas has been discharged, repair or maintenance can be performed, ensuring safer equipment maintenance. During normal operation of the first boiler 1 without maintenance on the various pipelines, pressure regulating valve blocks, filters, etc., if a discharge valve is not closed or is not closed tightly, resulting in a leak, the first gas detection probe 22 at the gas discharge port 23 of the main discharge pipe 25 can detect the leaking gas. The first gas detection probe 22 is connected to the first gas alarm 40 via a first line 38, and an alarm is issued, allowing the discharge valve to be repaired or replaced, thus preventing gas waste and eliminating potential hazards.

[0079] If leakage occurs in the gas pipelines, gas valves, pressure regulating valve groups, filters, etc. in the boiler room 36, the second gas detection probe 21 installed in the boiler room 36 can detect the leaked gas. The second gas detection probe 21 is connected to the second gas alarm 15 through the second line 18 and issues an alarm.

[0080] Since the second gas alarm 15 is controlled and connected to the automatic shut-off valve 13 via the third line 16 , the gas supply to the main air intake pipe 17 can also be automatically cut off, thereby ensuring safe use of gas in the boiler room 36 .

[0081] Although some specific embodiments of the present invention have been described in detail through examples, those skilled in the art will appreciate that the above examples are for illustration only and are not intended to limit the scope of the present invention. Those skilled in the art will appreciate that modifications may be made to the above embodiments without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
