The top end of the down pipe 2 is connected to a pipeline, and the shell 1 is filled with liquid to form a water seal, so that the gas carried in the input pipe 4 is not easy to leak from the overflow pipe 3. When the gas trap installed on the pipeline is used for drainage, the input pipe 4 is connected to the down pipe 2 by using the control assembly 5, and the press pipe 42 is cut off by using the press valve 421, so that the condensed water in the input pipe 4 flows to the overflow pipe 3 through the conducting assembly 9 to perform the drainage work.

Thus, the effect of online detection of the sealing performance of the gas trap is realized, the effect of removing the gas trap from the pipeline is reduced, and the labor intensity of the sealing performance detection of the gas trap is reduced.

[0043] In order to control the opening and closing of the input pipe 4 and the descending pipe 2, referring to Figures 1 to 3 , the control assembly 5 comprises a blind plate body 51, a lower gate valve 52 and an extension pipe 53. The bottom end of the descending pipe 2 and the input end of the lower gate valve 52 are in communication with each other, and the top end of the input pipe 4 and the bottom end of the extension pipe 53 are in communication with each other. The output end of the lower gate valve 52 is oppositely arranged with the top end of the extension pipe 53, and the blind plate body 51 is movably arranged between the output end of the lower gate valve 52 and the top end of the extension pipe 53. The blind plate body 51 comprises a communication part 511 and a blocking part 512, the communication part 511 is provided with a through hole, and the blocking part 512 is closed.

When the input pipe 4 is connected with the descending pipe 2, first move the blind plate body 51, move the communication part 511 of the blind plate body 51 between the output end of the lower gate valve 52 and the top end of the extension pipe 53, so that the output end of the lower gate valve 52 and the top end of the extension pipe 53 are connected through the communication part 511, then open the lower gate valve 52, realize the effect of connecting the input pipe 4 with the descending pipe 2. When the input pipe 4 is cut off with the descending pipe 2, first close the lower gate valve 52, then move the blind plate body 51, move the blocking part 512 of the blind plate body 51 between the output end of the lower gate valve 52 and the top end of the extension pipe 53, so that the output end of the lower gate valve 52 and the top end of the extension pipe 53 are blocked through the blocking part 512.

[0044] Referring to Figures 1 to 5 , the output end of the lower gate valve 52 is sleeved with an upper ring seat 62, and the upper ring seat 62 is welded with the lower gate valve 52. The extension pipe 53 is sleeved with a lower ring seat 63, and the lower ring seat 63 is welded with the extension pipe 53. The upper ring seat 62 is located above the lower ring seat 63, and the blind plate body 51 is movably arranged between the upper ring seat 62 and the lower ring seat 63. A plurality of upper through holes 621 are throughly provided on the upper ring seat 62, and a plurality of lower through holes 631 are throughly provided on the lower ring seat 63, and the oppositely arranged upper through holes 621 and lower through holes 631 are jointly arranged with a locking bolt 6. The locking bolt 6 penetrates the oppositely arranged upper through holes 621 and lower through holes 631, and the locking bolt 6 is threadedly connected with a locking nut 61. When the blind plate body 51 is moved, first loosen the locking nut 61 to separate the upper ring seat 62 from the lower ring seat 63, then shorten the extension pipe 53, so that the gap between the extension pipe 53 and the lower gate valve 52 is larger, thereby facilitating the movement of the blind plate body 51. After the blind plate body 51 is moved to the appropriate position, the locking nut 61 cooperates with the locking bolt 6 to fix the upper ring seat 62 and the lower ring seat 63, so that the extension pipe 53 and the lower gate valve 52 clamp the blind plate body 51, thereby fixing the blind plate body 51 between the extension pipe 53 and the lower gate valve 52.

[0045] Referring to Figures 1 to 6The upper ring plate 721 is sleeved on the telescopic pipe 53, and the upper ring plate 721 is welded with the telescopic pipe 53.

The bottom wall of one adjusting nut 71 is used for abutting against the top wall of the upper ring plate 721, and the top wall of the other adjusting nut 71 is used for abutting against the bottom wall of the lower ring plate 722. When the adjusting nut 71 above the upper ring plate 721 abuts against the top wall of the upper ring plate 721, and the adjusting nut 71 below the lower ring plate 722 abuts against the bottom wall of the lower ring plate 722, the adjusting screw 7 is fixed on the upper ring plate 721 and the lower ring plate 722. When the upper ring seat 62 is separated from the lower ring seat 63, the upper ring seat 62 is supported by the adjusting screw 7, so that the bending of the telescopic pipe 53 is reduced. When the telescopic pipe 53 is shortened, the adjusting nut 71 above the upper ring plate 721 is rotated to move away from the upper ring plate 721, so that the telescopic pipe 53 is shortened. When the telescopic pipe 53 is lengthened, the adjusting nut 71 below the lower ring plate 722 is rotated to move away from the lower ring plate 722, so that the telescopic pipe 53 is shortened.

[0046] The implementation principle of the gas trap convenient for pressure detection is as follows: when the gas trap installed on the pipeline is used for drainage, the input pipe 4 is connected with the downcomer 2, and the pressure pipe 42 is cut off by using the pressure valve 421, so that the condensed water in the input pipe 4 flows to the overflow pipe 3 through the conducting assembly 9 to perform the drainage work. When the gas trap installed on the pipeline is used for sealing detection, the input pipe 4 is cut off from the downcomer 2, then the pressure pipe 42 is connected with the nitrogen source, and then the pressure valve 421 is opened, so that the nitrogen is filled into the shell 1, and the actual pressure when the nitrogen breaks the water seal is obtained through the pressure gauge 41. The actual pressure is compared with the standard pressure, so that the effect of online detection of the sealing property of the gas trap is realized, the effect of removing the gas trap from the pipeline is reduced, and the labor intensity of the sealing detection of the gas trap is reduced.
