Technical Field

[0001] The present invention relates to the technical field of air valves, and specifically refers to a device for delaying the aging of winding air valves. Background Art

[0002] The winding process is the most important one among all spinning technologies. It can remove harmful defects in the yarn and transform the yarn from the bobbin state (not convenient for the next process production) into the form required by the customer, so as to obtain an ideal form and reliable quality.

[0003] At present, with the passage of time, the knotting air valves of many winding machines are constantly aging, and there is a risk in the knotting quality. There are design defects in the knotting air valves. During the knotting process, gas passes through the bottom of the air valve. In addition, the outer shell of the knotting air valve is made of plastic material and is often affected by air pressure. The plastic outer shell is easy to crack, resulting in damage to the air valve. Therefore, it is urgent to study a device for delaying the aging of winding air valves to solve the above problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the above technical defects and provide a device for delaying the aging of winding air valves with a simple structure, strong practicability and good use effect.

[0005] To solve the above technical problems, the technical solution provided by the present invention is: a device for delaying the aging of winding air valves, including an air valve body. The air valve body has a plastic housing and a bottom cover plate made of metal material. The bottom cover plate is buckled on the housing. It also includes a fastener that is hung on the outside of the housing and can wrap and fix the bottom cover plate. The fastener is arranged in a manner that fits the air valve body. The fastener is made of a steel wire bent into a frame structure with a certain elasticity. The fastener includes a semi-hanging ring with a circular ring-shaped bend in the middle part. On both sides of the semi-hanging ring, there are brackets in a U-shaped shape. One end of one bracket is provided with a hook, and the other end of the other bracket is provided with a bolt hook. On the cross-bar parts of both brackets, there are convex rod parts protruding upward, and the convex rod parts are used to tightly fix the bottom cover plate.

[0006] Further, the lower part of the air valve body is in a cuboid shape. The bottom cover plate is arranged at the bottom of the cuboid. Air valve holes are provided on both sides of the air valve body.

[0007] Further, on one side of the cuboid where the air valve hole is provided, there is a hanging post protruding from the surface, and on the opposite side, there is a horizontally arranged hanging rod.

[0008] Further, the hook is hung on one end of the hanging rod. A screw hole is provided at the other end of the hanging rod. The bolt passes through the bolt hook and is screwed into the screw hole.

[0009] Further, the included angles between the vertical rods of the two U-shaped brackets connected to the semi-hanging ring and the vertical line are both 10°. The vertical rods are arranged at positions avoiding the air valve holes.

[0010] Furthermore, the diameter of the semi-hanging ring is 22.5 mm.

[0011] Furthermore, the fastener is made of alloy steel, the Mo content of the alloy steel is 0.4-1.8% by mass, the Cr content is 1.86-1.92% by mass, the Mn content is 2.24-2.32% by mass, and the Ni, Cr and Si contents in the alloy steel are respectively less than 0.1% by mass.

[0012] The advantages of the present invention over the prior art are: after the fasteners are installed, the valve housing can be reinforced and stabilized when the winding is knotted, effectively reducing the pressure effect of the air pressure on the plastic shell of the valve housing, delaying the aging of the winding valve, making the plastic shell less likely to crack, reducing the damage to the valve caused by knotting air pressure, thereby improving the quality of yarn knotting.

[0021] A device for delaying the aging of a winding air valve, comprising an air valve body 1. The air valve body 1 has a plastic housing and a bottom cover plate made of metal. The bottom cover plate is buckled on the housing. It further includes a fastener 2 that is hung on the outside of the housing and can wrap and fix the bottom cover plate. The fastener 2 is arranged in conformity with the air valve body 1, and the fastener 2 is made of a steel wire bent into a frame structure with certain elasticity.

[0022] The lower part of the air valve body 1 is in a cuboid structure. A bottom cover plate is arranged at the bottom of the cuboid. Air valve holes 3 are provided on both sides of the air valve body 1. On one side of the cuboid where the air valve holes 3 are provided, there is a hanging post 4 protruding from the surface, and on the opposite side, there is a horizontally arranged hanging rod 5. The fastener 2 includes a semi-hanging ring 6 with a circular ring-shaped bend in the middle part. On both sides of the semi-hanging ring 6, there are brackets 7 in a U-shaped shape.

[0023] At one end of one side bracket 7, there is a hook 8, and at the end of the other side bracket 7, there is a bolt hook 9. The hook 8 is hung on one end of the hanging rod 5, and there is a threaded hole at the other end of the hanging rod 5. The bolt passes through the bolt hook 9 and is threadedly connected to the threaded hole. On the crossbar parts of both side brackets 7, there are protruding rod parts 10 protruding upwards, and the protruding rod parts 10 are used to tightly fix the bottom cover plate. The included angles between the vertical rods of the two U-shaped brackets 7 connected to the semi-hanging ring 6 and the vertical line are both 10°, and the vertical rods are arranged at positions avoiding the air valve holes 3. The diameter of the semi-hanging ring 6 is 22.5 mm.

[0024] The fastener 2 is made of alloy steel. In the alloy steel material, the Mo content is 0.4 - 1.8% by mass, the Cr content is 1.86 - 1.92% by mass, the Mn content is 2.24 - 2.32% by mass, and the contents of Ni, Cr, and Si in the alloy steel are each below 0.1% by mass.

[0025] In actual use, the half hanging ring 6 in the fastener 2 of the device is first hung on the hanging column 4 of the air valve body 1, and then the two U-shaped brackets 7 are passed around the bottom cover plate. The bottom of the bracket 7 is provided with a convex rod portion 10 protruding upward, so that the bottom cover plate can be pressed upward to play a good fixing effect. Then, the end of one bracket 7 with a hook 8 is hung on one end of the hanging rod 5, and the other is installed on the other end of the hanging rod 5 by using a bolt to pass through the screw hole, thereby effectively fitting the fastener 2 on the air valve body 1 and playing a good fixing effect on the air valve.

[0026] The invention can reduce the damage of the air valve, reduce the cost of spare parts, and improve the quality of yarn knotting. The air valve shell is made of white plastic material. Due to the effect of air pressure, the bottom cover of the air valve and the matching parts at the bottom of the shell are easily broken and damaged, causing damage to the entire air valve. The fastener 2 designed to match the air valve is made of alloy steel material, and the air valve body 1 and the fastener 2 are matched and fastened with bolts.
