[0029] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] See also Figure 1-3 A chemical pipeline leakage emergency treatment device comprises a flange 1, a side pipe 9 and a closing device. The flanges 1 are fixedly installed on both sides of the side pipe 9, and the closing device is rotatably installed in the inner cavity of the side pipe 9.

[0031] The closing device includes four rotating shafts 2, which are clamped on the inner side of the circular slide groove 5 to facilitate 180° rotation to the left and right. The four rotating shafts 2 are divided into two parts, the upper and lower parts. The outer surfaces of the two rotating shafts 2 located in the upper part are fixedly installed with upper fan blades 3, and the outer surfaces of the two rotating shafts 2 located in the lower part are fixedly installed with lower fan blades 4. The upper fan blades 3 and the lower fan blades 4 are both quarter-circular fan-shaped structures, and are made of corrosion-resistant sealing material.

[0032] In this embodiment, a coupling 11 is inserted between the left and right parts of the rotating shaft 2, and the upper and lower parts of the rotating shaft 2 are joined together by welding. The two rotating shafts 2 can slide relative to each other through the coupling 11, and the upper fan piece 3 and the lower fan piece 4 are formed into a closed circular structure through relative sliding.

[0033] Among them, fixed blocks and fixed grooves are provided on the left and right opposite sides of the rotating shaft 2 of the two parts, and the fixed blocks are snap-connected with the fixed grooves for easy fixation. A stopper 8 corresponding to the upper fan piece 3 is fixedly installed on the top surface of the inner wall of the side tube 9, and a stopper 8 corresponding to the lower fan piece 4 is also fixedly installed on the bottom surface of the inner wall of the side tube 9. The two stoppers 8 are used to limit the upper fan piece 3 and the lower fan piece 4, and a closing device is formed by air pressure. Gas detectors are fixedly installed on the outer surfaces of the two stoppers 8 for detecting alarms and triggering the closing device at the same time.

[0034] It should be noted that the chemical gas flows from the flange 1 on the right to the flange 1 on the left. When the gas flows normally, the upper fan blade 3 and the lower fan blade 4 face the flange 1 on the left. When leakage occurs, the shaft 2 rotates 180° to turn the upper fan blade 3 and the lower fan blade 4 toward the flange 1 on the right, and at the same time, opens and closes 90° around the corresponding shaft 2 to form a circular barrier.

[0035] An air intake valve 6 is inserted into the top of the side tube 9. The air intake valve 6 is arranged on the top surface of the inner wall of the side tube 9 near the left flange 1. A pipeline interface is arranged on the top surface of the air intake valve 6 to collect the gas outside the internal barrier of the side tube 9 through the air intake valve 6 to avoid leakage. A sealing layer 10 is fixedly installed on the side surface of the inner wall of the side tube 9 to protect the side tube 9. A circular slide groove 5 is arranged on the inner side of the sealing layer 10.

[0036] In this embodiment, 12 communication holes 7 are provided on the opposite sides of the outer surfaces of the two flanges 1. The radius of the 12 communication holes 7 is 1 cm. The communication holes 7 are connected to ordinary pipelines to facilitate the treatment of leaked gas in an extremely short pipeline distance.

[0037] The beneficial effects of the above embodiments are:

[0038] After a gas leak occurs, the gas flows to the block 8 and is detected by the detector, triggering an alarm. The rotating shaft 2 is rotated 180 degrees to adjust its position, and the upper fan blade 3 and the lower fan blade 4 are relatively unfolded to press against the two block blocks 8, so that a barrier is quickly formed to block gas transportation. The gas flowing through is circulated to a safe area through the suction valve 6 to avoid gas leakage, thereby achieving the effect of quickly sealing and absorbing the gas.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
