DETAILED DESCRIPTION

[0021] 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.

[0022] In order to solve the problem of single air pressure warning in the transmission pipeline in the prior art, the following technical solution is given. Figure 1-3 ;

[0023] A coke oven gas pressurized delivery device comprises a delivery pipeline 1, a connecting pipe 19 is connected to the delivery pipeline 1, a pressure detection device is connected to the top of the connecting pipe 19 through a flange 2, and the pressure detection device comprises a housing 3, a segmented piston cylinder 4, a runner 5 and a conductive sheet, the housing 3 is fixed to the top of the flange 2, a segmented piston cylinder 4 is provided at the inner bottom of the housing 3, the bottom surface of the segmented piston cylinder 4 is connected to the connecting pipe 19, a connecting block 18 is provided at the top of the segmented piston cylinder 4, a runner 5 is provided on one side of the connecting block 18, and the runner 5 is rollingly connected to the conductive sheet provided on the inner wall of the housing 3. The conductive sheet comprises a low-pressure conductive sheet 11, a normal-pressure conductive sheet 12 and a high-pressure conductive sheet 13, and the low-pressure conductive sheet 11, the normal-pressure conductive sheet 12 and the high-pressure conductive sheet 13 are longitudinally distributed from bottom to top.

[0024] Specifically, the gas in the conveying pipeline 1 enters the segmented piston cylinder 4 through the connecting pipe 19, and the segmented piston cylinder 4 extends upward under the action of air pressure. The air pressure of different strengths causes the segmented piston cylinder 4 to extend to different lengths. When the air pressure is low, the segmented piston cylinder 4 extends shorter, and when the air pressure is high, the segmented piston cylinder 4 extends longer. The extension and contraction of the segmented piston cylinder 4 drives the runner 5 to move longitudinally through the connecting block 18. When the air pressure in the conveying pipeline 1 changes, the height of the runner 5 changes accordingly. When the air pressure in the conveying pipeline 1 is low, the segmented piston cylinder 4 drives the runner 5 to contact the low-pressure conduction sheet 11; when the air pressure in the conveying pipeline 1 is normal, the runner 5 contacts the normal-pressure conduction sheet 12; when the air pressure in the conveying pipeline 1 is high, the runner 5 contacts the high-pressure conduction sheet 13.

[0025] The outer top of the shell 3 is respectively provided with a pressure indicating device, which includes a low-pressure indicator light 7, a normal-pressure indicator light 8 and a high-pressure indicator light 9. The bottom of the low-pressure indicator light 7 is electrically connected to a low-pressure alarm 17, and the bottom of the high-pressure indicator light 9 is electrically connected to a high-pressure alarm 10.

[0026] A rotating shaft 6 is provided on the axis of the rotating wheel 5, and both ends of the rotating shaft 6 are installed on the side of the connecting block 18 facing the conductive sheet through the connecting plate 14. The top surface of the connecting block 18 is connected to the inner bottom surface of the housing 3 through the spring 15. The spring 15, the rotating wheel 5, the rotating shaft 6, the low-pressure conductive sheet 11, the normal-pressure conductive sheet 12 and the high-pressure conductive sheet 13 are made of low-resistance and high-conductivity materials. The spring 15 can be connected in parallel with the low-pressure indicator light 7, the normal-pressure indicator light 8 and the high-pressure indicator light 9, and at the same time assist the segmented piston cylinder 4 to contract when the air pressure decreases.

[0027] Wires are arranged in the connecting plate 14, the connecting block 18 and the housing 3, and the low-pressure indicator light 7, the normal-pressure indicator light 8 and the high-pressure indicator light 9 are connected in parallel. The low-pressure indicator light 7, the normal-pressure indicator light 8 and the high-pressure indicator light 9 correspond to the low-pressure conductive sheet 11, the normal-pressure conductive sheet 12 and the high-pressure conductive sheet 13 respectively and form three sets of circuits. When the air pressure in the conveying pipeline 1 is low and the runner 5 contacts the low-pressure conductive sheet 11, the parallel circuit where the low-pressure indicator light 7 is located is connected, the low-pressure indicator light 7 is on and the low-pressure alarm 17 sounds an alarm; when the air pressure in the conveying pipeline 1 is normal and the runner 5 contacts the normal-pressure conductive sheet 12, the circuit where the normal-pressure indicator light 8 is located is connected and the normal-pressure indicator light 8 is on; when the air pressure in the conveying pipeline 1 is too high, the runner 5 contacts the high-pressure conductive sheet 13, the circuit where the high-pressure indicator light 9 is located is connected, the high-pressure indicator light 9 is on and the high-pressure alarm 10 sounds an alarm.

[0028] A pressure regulating valve 16 is also provided on the conveying pipeline 1. The pressure regulating valve 16 is respectively connected to the signals of the low-pressure alarm 17 and the high-pressure alarm 10. When the low-pressure alarm 17 sounds an alarm, the pressure regulating valve 16 can be controlled to open automatically, thereby increasing the pressure in the conveying pipeline 1 through the pressure regulating valve 16; when the high-pressure alarm 10 sounds an alarm, the pressure regulating valve 16 is controlled to release excess pressure, thereby ensuring the safety of the pipeline.

[0029] Working principle: The gas in the conveying pipeline 1 enters the segmented piston cylinder 4 through the connecting pipe 19. The segmented piston cylinder 4 extends upward under the action of air pressure. The air pressure of different strengths causes the extension length of the segmented piston cylinder 4 to be different. When the air pressure in the conveying pipeline 1 is low, the segmented piston cylinder 4 drives the rotor 5 to contact the low-pressure conduction sheet 11; when the air pressure in the conveying pipeline 1 is normal, the rotor 5 contacts the normal-pressure conduction sheet 12; when the air pressure in the conveying pipeline 1 is high, the rotor 5 contacts the high-pressure conduction sheet 13, thereby connecting different circuits, so that the low-pressure indicator light 7, the normal-pressure indicator light 8 and the high-pressure indicator light 9 can give corresponding indications according to the air pressure conditions in the conveying pipeline 1. The low-pressure alarm 17 and the high-pressure alarm 10 can control the pressure regulating valve 16 to make preliminary adjustments to the air pressure of the conveying pipeline 1 to ensure the safety of the conveying pipeline 1 while sounding the alarm.
