Description

Technical Field

[0001] The utility model relates to the technical field of chemical fiber production, in particular to an adjusting and fixing device for preventing accidental touching of an air valve. Background Art

[0002] Side-blown cooling of chemical fibers is a key spinning technology used to control and optimize fiber quality and production efficiency. During the chemical fiber production process, cooling air is blown laterally through a side-blown device to quickly cool the melt stream extruded from the spinneret and solidify it into filaments. This process is crucial to the physical properties and structural uniformity of the fiber. During the process, the temperature, humidity, pressure, and rapidity of the cooling air must be kept stable to ensure the uniform shape of the chemical fiber.

[0003] The air valve handwheel and valve stem connected to the side blowing device are easily accidentally touched by technicians during inspection and maintenance, causing changes in the air valve flow rate (the air valve adjustment fixture of application number CN202122312448.5 also mentioned this technical problem in the background technology), and will affect the quality of the chemical fiber. Moreover, this accidental touch is not easy to observe, and it is impossible to know the number of turns of the valve stem caused by the accidental touch. The purpose of this utility model is to propose a new device to solve the above technical problems. Utility Model Content

[0019] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.

[0020] Example 1:

[0021] like Figure 1-Figure 4 As shown, the utility model discloses a device for adjusting and fixing an air valve to prevent accidental touching, comprising:

[0022] The mounting plate 1 is arranged between the side blowing device and the air valve. A through hole 102 is formed on the mounting plate 1 for the air valve stem 101 to pass through. The mounting plate 1 is also provided with a screw hole 103 for the bolt to pass through and connect with the side blowing device. During normal assembly, the mounting plate 1 is fixed to the side blowing device by bolts. The side blowing device is an existing known device. It is only necessary to fix the mounting plate 1 to the side blowing device and ensure that the limiting ring 301 on the mounting seat 3 can cooperate with the air valve stem 101.

[0023] The threaded portion 2 is formed on the damper stem 101; that is, the damper stem 101 is provided with a thread, which can cooperate with the opening 402 of the ring 401. When the damper stem 101 rotates, the thread drives the ring 401 to rotate;

[0024] The mounting seat 3 is located on the top surface of the mounting plate 1 and is fixed to the mounting plate 1. A limiting ring 301 is formed on the mounting seat 3 for the air valve stem 101 to pass through. The limiting ring 301 matches the shape of the air valve stem 101;

[0025] The mounting bar 4 and the mounting seat 3 form a movable pair, that is, a slide groove is provided on the mounting seat 3, and the mounting bar 4 is inserted into the slide groove and can be slidably connected. A circular ring 401 is rotatably provided on one end of the mounting bar 4. The circumferential surface of the circular ring 401 is provided with openings 402 at equal intervals. The threaded portion 2 abuts against the openings 402 and is in mating connection;

[0026] Scale plate 5, which is arranged inside the ring 401 and connected to the ring 401, corresponds to the opening 402, and can be observed from the outside of the ring 401 through the opening 402; the corresponding scale plate 5 is marked on the scale plate 5;

[0027] Under normal circumstances, when the air valve stem 101 is adjusted to the required opening, the mounting strip 4 is inserted into the slide groove so that the opening 402 of the ring 401 cooperates with the threaded portion 2 on the valve stem 101. At this time, the pointer 403 on the mounting strip 4 should correspond to the scale plate 5 of the 0 scale on the ring 401, and the 0 scale is respectively extended to both sides in the order of clockwise 1, clockwise 2, clockwise 3 and counterclockwise 1, counterclockwise 2, counterclockwise 3. When the valve stem 101 is accidentally touched and causes the valve stem 101 to rotate one circle clockwise, the scale plate 5 of the clockwise 1 on the ring 401 corresponds to the pointer 403. When the valve stem 101 is accidentally touched and causes the valve stem 101 to rotate one circle counterclockwise, the scale plate 5 of the counterclockwise 1 on the ring 401 corresponds to the pointer 403. And so on, so as to clearly indicate the situation of the valve stem 101 rotating due to accidental touching, which is convenient for the operator to call back.

[0028] A pointer 403 is horizontally arranged on the mounting bar 4;

[0029] The latch 6 can pass through the mounting strip 4 , and a pin hole 601 that can cooperate with the latch 6 is opened on the top surface of the mounting plate 1 .

[0030] It also includes a movable magnet bar 7 and a fixed magnet bar 8. The movable magnet bar 7 is connected to the inner side of the ring 401, and the fixed magnet bar 8 is connected to the top surface of the mounting plate 1. The movable magnet bar 7 and the fixed magnet bar 8 attract each other.

[0031] When the valve stem 101 is opened to the desired position, during the process of inserting the mounting bar 4 into the slide slot, the ring 401 rotates to the closest position between the movable magnet bar 7 and the fixed magnet bar 8 under the mutual attraction between the two. At this time, the scale plate 5 of the 0 scale is aligned with the pointer 403, realizing automatic adjustment without manual adjustment by personnel to cause misadjustment.

[0032] Working principle: When the air valve stem 101 needs to be actively rotated, the technician removes the latch 6 from the mounting bar 4 to release the restriction on the mounting bar 4, and then pulls the mounting bar 4 outward. Since the ring 401 is set on the mounting bar 4, the ring 401 will move outward synchronously with the mounting bar 4. At this time, the opening 402 on the ring 401 is separated from the threaded part 2 on the valve stem 101. The technician will not interfere with the ring 401 when rotating the air valve stem 101. In addition, the opening 402 on the ring 401 and the threaded part 2 After separation, under the influence of the attraction of the movable magnet bar 7 and the fixed magnet bar 8 and the gravity of the movable magnet bar 7, the ring 401 will rotate so that the end of the ring 401 provided with the movable magnet bar 7 is located at the bottom of the ring 401. It should be noted that after the process of actively rotating the air valve stem 101 is completed, the mounting bar 4 needs to be reset so that the opening 402 of the ring 401 is against the threaded part 2 and the mounting bar 4 is fixed by using the pin 6 and the pin hole 601. At this time, the pointer 403 should be aligned with the scale plate 5 of the 0 scale.

[0033] When the damper stem 101 is accidentally touched, the threaded portion 2 will rotate synchronously with the damper stem 101. Since the threaded portion 2 is against the opening 402 on the ring 401, the threaded portion 2 will drive the ring 401 to rotate during the rotation process. A scale plate 5 is provided on the inside of the ring 401. The technician can know the number of rotations and the rotation direction of the damper stem 101 by observing the cooperation between the scale plate 5 and the pointer 403, which is convenient for the subsequent resetting of the damper stem 101.
