When sampling is required, the blocking mechanism is opened for sampling, and then automatically blocked after the sampling is completed, so as to complete the sampling process. The blocking mechanism includes a The sliding sleeve 3 and the plugging head 10 fixedly arranged on the inner side of the sampling branch pipe 2, when the bottom of the sliding sleeve 3 is in close contact with the plugging head 10, the plugging head 10 blocks the sliding sleeve 3 to ensure the sealing of the sampling branch pipe 2 when no sampling is taken, and trigger members are arranged on both sides of the sliding sleeve 3, when the trigger members drive the sliding sleeve 3 to slide upward, the plugging head 10 releases the blocking state of the sliding sleeve 3 and performs sampling, ensuring that the sampling bottle 4 at this time can sample the liquid inside the sampling tube.
[0022] Preferably, the bottom of the sampling branch tube 2 of the utility model is provided with a pointed end, which ensures that the sampling branch tube 2 can be inserted into the interior of the sampling bottle, so that the liquid inside the main line 1 can be introduced into the interior of the sampling bottle. At the same time, when sampling, the bottom of the sampling branch tube 2 is inserted into the interior of the sampling bottle 4, and the top of the sampling bottle 4 is provided with a sampling port 5. The top of the sampling bottle 4 pushes the sleeve 3 to slide upward, thereby triggering the sleeve 3 to slide upward, so that the blocking head 10 no longer blocks the passage of the sleeve 3, and a limiting plate 6 is provided inside the sampling tube. A sealing sleeve 8 is provided at the bottom of the limiting plate 6. The sealing sleeve 8 is slidably connected to the interior of the sleeve 3 to prevent the liquid inside the main line 1 from corroding and damaging the thrust spring 7.
[0023] See also Figure 1 to Figure 4In addition, a thrust spring 7 is provided between the top of the sliding sleeve 3 and the bottom of the limit plate 6 of the utility model. When the sliding sleeve 3 is not under force, the thrust spring 7 pushes the sliding sleeve 3 downward so that the bottom of the sliding sleeve 3 abuts against the top of the blocking head 10, so that the blocking head 10 blocks the channel of the sliding sleeve 3 and completes the blocking of the sampling tube. A conical portion 32 is provided on the contact surface between the sliding sleeve 3 and the blocking head 10, and a blocking portion cooperating with the conical portion 32 is provided on the top of the blocking head 10. The blocking portion and the conical portion 32 cooperate to reliably block the channel of the sliding sleeve 3.
[0024] Furthermore, the trigger member of the utility model is a protruding structure 31, which ensures that the trigger member can be triggered by being abutted by the sampling bottle. The side wall of the sampling branch tube 2 is provided with a slide groove 9 that cooperates with the protruding structure 31. The protruding structure 31 is guided by the slide groove 9. The outer side of the sleeve 3 is a sealing surface 33.

When sampling is needed, the sampling branch tube 2 is inserted into the interior of the sampling bottle, and then the top of the sampling bottle is lifted up by the protruding structure 31. At this time, the sleeve 3 is separated from the plugging head 10, and the liquid is guided to the sampling branch tube 2 through the channel of the sleeve 3 and enters the interior of the sampling bottle. When sampling is completed, the sampling bottle is directly moved downward and taken out. At this time, the sleeve 3 directly abuts against the plugging head 10 to block the channel, completing the real-time blocking process of the sampling branch tube 2.

The blocking mechanism comprises a sliding sleeve slidably connected to the inside of the sampling branch pipe and a blocking head fixedly arranged on the inner side of the sampling branch pipe. When the bottom of the sliding sleeve is in close contact with the blocking head, the blocking mechanism is The head blocks the sliding sleeve to ensure the sealing of the sampling branch tube when no sampling is taken. Trigger members are provided on both sides of the sliding sleeve. When the trigger member drives the sliding sleeve to slide upward, the blocking head releases the blocking state of the sliding sleeve and performs sampling to ensure that the sampling bottle at this time can sample the liquid inside the sampling tube.
