Description

Technical Field

[0001] This utility model relates to the field of three-way feeding valve technology, specifically to a novel feeding structure for a three-way feeding valve. Background Technology

[0002] The three-way alloy charging valve at the 210 converter plant of Lianyuan Steel often experiences valve plate jamming, leading to untimely alloy charging during steelmaking and affecting the quality of the steel. The closest prior art known to this invention is a three-way feed valve, in which a flapper rotates within the valve body to switch between two outlets. What are the advantages and disadvantages of the prior art? The advantage is its simple structure, while the disadvantage is that the flapper wears out quickly and is easily damaged, and small particles can easily get stuck between the flapper and the valve body, causing the valve plate to jam. Utility Model Content

[0003] The technical problem this utility model aims to solve is that the existing three-way feed valve flaps wear out quickly and are easily damaged, and small particles easily get stuck between the flaps and the valve body, causing the valve plate to jam.

[0004] To solve the above problems, the technical solution adopted by this utility model is a new feeding structure for a three-way feeding valve, including a valve body, a shaft inside the valve body, and a valve core located outside the shaft inside the valve body and swinging.

[0005] The valve body has a three-way structure, with the inlet at the top and a pair of outlets at the bottom.

[0006] The valve core structure includes a guide end and a discharge end. The area of ​​the guide end port must be larger than the area of ​​the chute outlet installed above the three-way discharge valve, and the area of ​​the discharge end port must be smaller than the area of ​​the valve body discharge port.

[0007] As a further embodiment of this utility model: bearing seats are fixed on both sides of the valve body at the shaft connection by a number of screws to limit the position of the shaft.

[0008] As a further aspect of this utility model, the valve core rotation angle is fifty degrees.

[0009] As a further embodiment of this utility model: the guide end of the valve core has an arc-shaped curved surface structure, which can prevent the valve core from colliding and getting stuck with the valve body when rotating, and can maximize the material receiving port to prevent material from overflowing.

[0010] The advantages of this utility model compared with the prior art are as follows:

[0011] This application redesigns the valve core structure to eliminate material jamming and obstruction, while also meeting the requirement for convenient valve core replacement, greatly reducing the on-site failure rate and making equipment maintenance costs far lower than similar products on the market.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] This utility model provides a technical solution to address the existing problems mentioned in the background art.

[0019] Combined with appendix Figure 1-2 First, install shaft 2 in the pre-designed position inside valve body 1. Secure bearing seats 4 firmly with several screws at the connection points of shaft 2 on both sides of valve body 1 to precisely define the position of shaft 2 and ensure it does not shift during operation. Next, install valve core 3 on the outside of shaft 2, allowing it to swing around shaft 2 inside valve body 1. When installing valve core 3, ensure that the guide end of the valve core is on the same vertical axis as the valve body's feed inlet. This prevents the valve core from colliding and jamming with the valve body during rotation and maximizes the feed inlet, preventing material overflow.

[0020] The rotation angle of valve core 3 is adjusted. Through special debugging tools or mechanical structures, the rotation angle of valve core 3 is precisely set to fifty degrees to ensure that valve core 3 can accurately control the flow direction of material during the swing process and realize reasonable switching between the two discharge ports 1 and 2.

[0021] After completing the above installation and adjustments, conduct a comprehensive test of the entire three-way feeding valve's new feeding structure. Slowly introduce simulated material into the feed inlet 1.1 at the top of the valve body 1, and observe whether the valve core 3 swings smoothly and whether the material flows out from the corresponding discharge outlet 1.2 as expected. If any problems are found, adjust and repair the relevant components in a timely manner until the entire device operates normally.

[0022] The working principle of this utility model is as follows: When it is necessary to perform operations such as alloy feeding, the material enters the interior of the valve body 1 from the feed port 1.1 at the top of the valve body 1.

[0023] An external power device, such as a cylinder, drives shaft 2 to rotate, causing valve core 3 to oscillate around shaft 2. When valve core 3 oscillates to a certain position, its discharge end 3.2 aligns with a discharge port 1.2 at the bottom of valve body 1, at which point material flows out from that discharge port 1.2. Because the area of ​​discharge end 3.2 is smaller than the area of ​​discharge port 1.2 of valve body 1, this design allows for better control of material flow rate and direction. When it is necessary to switch discharge ports 1.2, the power device continues to drive shaft 2 to rotate valve core 3 by fifty degrees, causing valve core 3 to oscillate to a position aligned with another discharge port 1.2, from which material flows out.

[0024] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
