First, the pressure relief base is passed through one end of the suction main pipe, and then the movable plate is fixed in the pressure relief base through the fixed plate. Then the sealing block is connected through the spring so that the sealing block can seal one end of the suction main pipe under the action of elasticity. When the negative pressure in the suction main pipe is large, the sealing block will move into the suction main pipe to relieve pressure, thereby avoiding excessive negative pressure affecting chemical fiber spinning.

[0027] In another embodiment, if Figure 4 and Figure 5 As shown, a pressure relief base 6 is passed through and fixedly connected to the inner side of one end of the suction main pipe 1, and a fixed plate 14 is fixedly connected to the inner side of one end of the pressure relief base 6 through four connecting blocks 16, so that there is a gap between the fixed plate 14 and the pressure relief base 6, and four sliding blocks 19 are slidably installed on the inner side of the other end of the pressure relief base 6 through a guide rail to facilitate the movement of the movable plate 18, and a movable plate 18 is fixedly connected between the four sliding blocks 19, and a spring 20 is fixedly connected to one side of the movable plate 18, so that the sealing block 17 will be pulled when the negative pressure is large.

Due to the elastic effect of the spring 20, the sealing block 17 is fitted with the inner wall of one end of the air intake main pipe 1. When the position of the movable plate 18 moves, the elasticity of the spring 20 located between the movable plate 18 and the sealing block 17 will change. When the negative pressure exceeds the standard, the suction force of the negative pressure on the sealing block 17 will pull the sealing block 17, so that the sealing block 17 continues to stretch the spring 20, so that the negative pressure in the air intake main pipe 1 is released through the gap between the pressure relief base 6 and the movable plate 18.

[0031] The above embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
