Abstract
Description
Technical Field
[0001] This utility model relates to the field of valve technology, specifically to a dual valve with controllable discharge volume. Background Technology
[0002] In industrial production, material discharge control is a crucial step. Traditional discharge valves often have problems. Regarding material adaptability, most traditional valves can only handle materials with good flowability. When encountering materials with poor flowability or prone to bridging, they frequently experience blockages and uneven discharge, greatly limiting the diversity of production processes and making it difficult to meet the production needs of various products. This increases the complexity and cost of material handling. In terms of the accuracy of discharge control, traditional single valves lack an effective and precise adjustment mechanism, making it difficult to accurately control the discharge flow rate. This can easily lead to inconsistent discharge volumes, resulting in inconsistent product quality. Moreover, during the material feeding process, the lack of effective air pressure control often causes air pressure fluctuations, which can lead to poor feeding, further exacerbating the instability of the discharge volume, reducing production efficiency, and potentially causing production interruptions. This increases equipment maintenance costs and downtime, affecting the smoothness and reliability of the entire production process.
[0003] By setting up a dual valve with controllable discharge volume, the above problems can be effectively solved through dual valve control and air pressure regulation functions, thereby improving the level of material discharge control. Utility Model Content

[0016] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.
[0017] Example: Please refer to Figure 1 - Figure 4 This utility model provides a technical solution: a dual valve with controllable discharge volume, including: a hopper 1, a discharge pipe 2 fixedly connected to the outer wall of the bottom of the hopper 1, two discharge pipes 2, a discharge valve 3 fixedly connected to the outer wall of the discharge pipe 2, a connecting pipe 4 fixedly connected to the outer wall of the bottom of one discharge pipe 2, a pipe short connector 8 fixedly connected to the outer wall of the top of the other discharge pipe 2, an exhaust pipe 5 fixedly connected to the inner wall of the connecting pipe 4, and a regulating valve 6 rotatably connected to the inner wall of the exhaust pipe 5;
[0018] The discharge valve 3 includes a servo motor 31. The output end of the servo motor 31 is fixedly connected to a drive shaft 32. A rotating block 33 is fixedly connected to the outer wall of the drive shaft 32. A fixed ring 34 is rotatably connected to the outer wall of the drive shaft 32. A vent cap 7 is threadedly connected to the side of the exhaust pipe 5 away from the connecting pipe 4. The outer wall of the bottom of the connecting pipe 4 is fixedly connected to the outer wall of the top of the pipe short circuit 8. After the servo motor 31 is started, the drive shaft 32 at its output end rotates, driving the rotating block 33 to rotate. Since the drive shaft 32 is rotatably connected to the fixed ring 34 and the fixed ring 34 is fixed on the discharge pipe 2, the rotation of the rotating block 33 will change the gap of the discharge pipe 2 and drive the material to fall. After the material passes through the connecting pipe 4 and the pipe short circuit 8, it falls into the second discharge valve 3 and is controlled by the second discharge valve 3, thereby precisely adjusting the flow rate of the material. This control method can adapt to the material output requirements of different production processes. In addition to handling materials with good flowability, it can also handle materials with poor flowability that are prone to bridging.
[0019] The inner sidewall of the fixed ring 34 is fixedly connected to the outer sidewall of the feed tube 2, the outer wall of the drive shaft 32 is rotatably connected to the inner wall of the feed tube 2, the outer wall of the fixed ring 34 is fixedly connected to the outer wall of the servo motor 31, and the outer wall of the drive shaft 32 is rotatably connected to the inner wall of the fixed ring 34.
[0020] The regulating valve 6 includes a rotating shaft 61, a rotating plate 62 fixedly connected to the outer wall of the rotating shaft 61, and a friction block 63 fixedly connected to the end of the rotating shaft 61 away from the rotating plate 62. The outer wall of the rotating shaft 61 is rotatably connected to the inner wall of the exhaust pipe 5, and the outer wall of the rotating plate 62 is slidably connected to the inner side wall of the exhaust pipe 5. The exhaust pipe 5 and the regulating valve 6 inside it are mainly used to regulate the air pressure in the feed pipe 2. When the material falls, the air pressure in the feed pipe 2 may change, affecting the stability of the feeding. Rotating the rotating shaft 61 of the regulating valve 6 drives the rotating plate 62 to rotate inside the exhaust pipe 5, changing the size of the ventilation cross section of the exhaust pipe 5, thereby regulating the air pressure in the feed pipe 2.
[0021] Working principle:
[0022] In use, the material in the hopper 1 is discharged through the discharge pipe 2. The discharge valve 3 can precisely control the discharge amount of the material. After the servo motor 31 is started, the transmission shaft 32 at its output end rotates, which drives the rotating block 33 to rotate. Since the transmission shaft 32 is rotatably connected to the fixed ring 34 and the fixed ring 34 is fixed on the discharge pipe 2, the rotation of the rotating block 33 will change the gap of the discharge pipe 2 and drive the material to fall. After the material passes through the connecting pipe 4 and the pipe short-circuit 8, it falls into the second discharge valve 3 and is controlled by the second discharge valve 3, thereby precisely adjusting the flow rate of the material. This control method can adapt to the material discharge requirements of different production processes. In addition to handling materials with good flowability, it can also handle materials with poor flowability that are prone to bridging. It has strong versatility, improves the accuracy of production and the stability of product quality, and reduces material waste.
[0023] The exhaust pipe 5 and its internal regulating valve 6 are mainly used to regulate the air pressure in the discharge pipe 2. When the material falls, the air pressure in the discharge pipe 2 may change, affecting the stability of the discharge. Rotating the rotating shaft 61 of the regulating valve 6 drives the rotating plate 62 to rotate inside the exhaust pipe 5, changing the size of the ventilation cross-section of the exhaust pipe 5, thereby regulating the air pressure in the discharge pipe 2. The friction block 63 can increase the friction force when the rotating shaft 61 rotates, so that the rotating plate 62 can be rotated better. The vent cap 7 can prevent dust and other impurities from entering the exhaust pipe 5 while expelling air. By adjusting the ventilation volume of the exhaust pipe 5, the material can be discharged in a stable air pressure environment, avoiding problems such as poor discharge and unstable output caused by air pressure fluctuations, improving the reliability and stability of the entire discharge system, and making the production process smoother and more efficient. The connecting pipe 4 and the pipe short connector 8 serve to connect and adapt the pipe structure, ensuring the integrity and functionality of the entire dual-valve system.
