Most of the existing natural gas transmission pipelines control the transmission of natural gas flow by installing a number of valves, and cannot automatically distribute the gas according to the transmission pressure. When the natural gas transmission volume in the pipeline increases instantaneously, it is difficult for the user to quickly open the valve, which can easily cause the pressure of the natural gas in the pipeline to increase rapidly, posing certain safety hazards to the use of the transmission pipeline.

[0016] Compared with the prior art, the utility model provides a device for realizing automatic distribution of natural gas pipelines, which has the following beneficial effects:

[0026] Embodiment 1: A device for realizing automatic distribution of natural gas pipelines, comprising a main delivery pipeline 1, on which a main valve 2 is arranged, the side of the main delivery pipeline 1 is connected with a side connecting pipe 3, the two sides of the side connecting pipe 3 are symmetrically connected with two distribution connecting pipes 4, each of which is provided with an electromagnetic valve body 5, and the side of the side connecting pipe 3 is provided with an electromagnetic valve timely triggering component 6 for automatic distribution triggering.

[0027] The electromagnetic valve timely trigger component 6 includes a side trigger chamber 601 arranged at the end of the side connecting pipe 3, the side trigger chamber 601 is connected to the side connecting pipe 3, a sliding connecting plate 602 is slidingly arranged in the side trigger chamber 601, two limiting sliding grooves 603 are symmetrically arranged on both sides of the inner wall of the sliding connecting plate 602, the end of the sliding connecting plate 602 is slidably inserted in the limiting sliding groove 603, and a closing piston block 604 is arranged on the side of the sliding connecting plate 602.

[0028] A trigger resistance rod 605 is vertically arranged on the other side of the sliding connecting plate 602, and the end of the trigger resistance rod 605 passes through the side of the sliding connecting plate 602. Two resistance springs 606 are symmetrically arranged on the side of the sliding connecting plate 602, and the ends of the resistance springs 606 are connected to the inner wall of the sliding connecting plate 602. A side connecting frame 607 is arranged on the outer side of the side trigger compartment 601, and a switch mounting seat 608 is arranged in the middle of the side connecting frame 607, and a switch mounting groove 609 is opened on the side of the switch mounting seat 608.

[0029] A trigger switch 610 is arranged in the switch mounting groove 609, and two protective connecting rods 611 are symmetrically arranged on the sides of the trigger switch 610. The ends of the protective connecting rods 611 pass through the sides of the switch mounting seat 608. A connecting spring 612 is sleeved on the rod body of the protective connecting rod 611. One end of the connecting spring 612 is connected to the rod body of the protective connecting rod 611, and the other end of the connecting spring 612 is connected to the switch mounting seat 608. Valve connecting lines 613 are symmetrically connected to both sides of the trigger switch 610, and the ends of the valve connecting lines 613 are connected to the electromagnetic valve body 5.

[0030] Embodiment 2: The difference between this embodiment and embodiment 1 is that a sealing gasket is provided at the sliding connection between the trigger resistance rod 605 and the side trigger compartment 601 .

[0031] When the trigger resistance rod 605 slides on the side trigger chamber 601 , leakage of natural gas entering into the side trigger chamber 601 is prevented.

[0032] Embodiment 3: The difference between this embodiment and embodiment 1 is that a resisting rubber block is provided at the end of the trigger resisting rod 605 .

[0033] This makes the trigger resistance rod 605 safer when resisting triggering the trigger switch 610 .

[0034] Embodiment 4: The difference between this embodiment and embodiment 1 is that a connecting block is provided at the end of the protective connecting rod 611 .

[0035] This blocks the end of the connecting spring 612 sleeved on the protective connecting rod 611 .

[0036] In this embodiment, since most of the existing natural gas transmission pipelines control the transmission of natural gas flow by installing a number of valves, they cannot automatically distribute the gas according to the transmission pressure. Therefore, when the natural gas transmission volume in the pipeline increases instantaneously, it is difficult for the user to quickly open the valve, which can easily cause the pressure of the natural gas in the pipeline to increase rapidly, and there are certain safety hazards in the use of the transmission pipeline.

[0037] In summary, in the specific implementation, when the natural gas flowing through the main transmission pipeline 1 increases instantaneously, and the main valve 2 is not opened in time, the instantaneously increased natural gas pressure in the main transmission pipeline 1 will gradually increase, and at the same time enter the branch transmission connecting pipe 4 through the side connecting pipe 3, while the electromagnetic valve body 5 installed on the branch transmission connecting pipe 4 is in a closed device. When the pressure of the natural gas entering the side connecting pipe 3 gradually increases, it will resist the closing piston block 604 slidingly set in the side trigger chamber 601 in the electromagnetic valve timely trigger component 6, when the natural gas pressure is greater than the spring support force of the resistance spring 606 set on the side of the closing piston block 604.

[0038] The sliding connecting plate 602 on the closing piston block 604 will slide in the side trigger chamber 601, so that the trigger resistance rod 605 moves to the side close to the trigger switch 610. When the natural gas pressure continues to increase, the end of the trigger resistance rod 605 will trigger the switch 610 to resist, so that the trigger switch 610 is triggered to open after being resisted, and the electromagnetic valve body 5 set on the distribution connecting pipe 4 is opened through the valve connecting line 613, so that the increased natural gas in the main pipeline 1 can enter the distribution connecting pipe 4 through the side connecting pipe 3.

[0039] The natural gas can be safely distributed and discharged through the distribution connecting pipe 4, thereby preventing the natural gas in the main pipeline 1 from increasing continuously and being unable to be discharged in time, avoiding the risk of the main pipeline 1 bursting, and being able to timely and effectively distribute the natural gas that increases in the main pipeline 1 in a short period of time, thereby ensuring the safe transportation of natural gas and facilitating safe use by users.
