Description

Technical Field

[0001] The utility model relates to the technical field of wing valves, in particular to a multi-channel wing valve. Background Art

[0002] In the process of solid particle treatment, the wing valve is a key control element and its performance directly affects the effect of the treatment process.

[0003] The traditional wing valve has a large outlet opening and a serious gas backflow problem, especially when the valve plate is just opened. The gap on the upper part can easily cause gas backflow, affecting the stability of the treatment process.

[0004] Therefore, it is particularly important to design a multi-channel wing valve that can effectively prevent gas backflow. Utility Model Content

[0005] In view of the above problems, the utility model provides a multi-channel wing valve.

[0006] In order to solve the above problems, the technical solution adopted by the utility model is:

[0007] A multi-channel wing valve comprises a material leg, a lifting ring bracket, a first lifting ring, a second lifting ring, a first wing valve plate, a second wing valve body, a pneumatic valve and a compressed air pipeline;

[0008] The material leg is an input channel for solid particles, and the material leg is fixedly connected to the lifting ring bracket. A first wing valve plate and a second wing valve body are provided at the lower end of the lifting ring bracket, and the first wing valve plate and the second wing valve body are fixedly connected.

[0009] Preferably, the first wing valve plate is controlled by a pneumatic valve to realize the opening and closing of the valve plate, and the second wing valve body and the first wing valve plate form a multi-channel structure, and precise control of the solid particle flow rate is achieved by adjusting the angle and position of the valve plate.

[0010] Preferably, a pressure measurement interface is provided on the feed leg, and the pressure measurement interface is used to monitor the pressure change in the feed leg in real time, so as to determine the flow state of the solid particles.

[0011] Preferably, a first lifting ring and a second lifting ring are installed on the lifting ring bracket to facilitate the lifting and installation of the entire wing valve.

[0012] Preferably, when the catalyst in the feed leg starts to be discharged, the pneumatic valve controls the first wing valve plate to open, and the catalyst flows out.

[0013] Preferably, the opening angle of the first wing valve plate increases accordingly with the increase of discharge volume to accommodate a larger flow rate. When the discharge volume decreases or stops, the pneumatic valve controls the first wing valve plate to gradually close until it is completely closed to prevent gas backflow.

[0014] Preferably, the angle between the second wing valve body and the first wing valve plate enables solid particles to be buffered when flowing through the wing valve.

[0015] The beneficial effects of the utility model are:

[0016] 1. Through the precise control of pneumatic valves and compressed air pipelines, the solid particle flow rate can be precisely adjusted. This precise control not only ensures the stability of the treatment process, but also greatly improves the treatment efficiency. During the catalyst discharge process, as the discharge volume changes, the wing valve plate can automatically adjust the opening and closing angle to ensure that the flow rate matches the discharge volume, avoiding the problem of resource waste or poor treatment effect caused by excessive or insufficient flow.

[0017] 2. The special multi-channel design allows an effective isolation layer to be formed between the solid particles and the gas when the valve plate is closed, thereby effectively preventing the occurrence of gas backflow. Especially when the discharge volume is reduced or stopped, the wing valve plate can be quickly closed to avoid equipment damage or safety accidents caused by gas backflow. This design not only ensures the safety of the treatment process, but also extends the service life of the equipment.

[0018] 3. The pressure measurement interface is set on the material leg, and the multi-channel wing valve can monitor the pressure changes in the material leg in real time. Once the pressure fluctuates abnormally, the system can immediately issue an alarm and take corresponding treatment measures to ensure the stability of the treatment process. This real-time monitoring function enables operators to discover and deal with possible problems in a timely manner, avoiding production interruptions or product quality degradation caused by unstable treatment processes.

[0019] 4. The modular design is adopted, and the components are tightly connected and compact in structure. At the same time, in order to facilitate installation and maintenance, it is also equipped with lifting devices such as lifting ring brackets and lifting rings. These designs make the installation and maintenance process simpler and faster, reducing the labor intensity and maintenance costs of operators. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Reference Figure 1-3 , a multi-channel wing valve, comprising a material leg 1, a lifting ring bracket 3, a first lifting ring 4, a second lifting ring 5, a first wing valve plate 6, a second wing valve body 7, a pneumatic valve 8 and a compressed air pipeline 9;

[0028] The material leg 1 is an input channel for solid particles. The material leg 1 is fixedly connected to the lifting ring bracket 3. The lower end of the lifting ring bracket 3 is provided with a first wing valve plate 6 and a second wing valve body 7. The first wing valve plate 6 and the second wing valve body 7 are fixedly connected.

[0029] Furthermore, the first wing valve plate 6 is controlled by the pneumatic valve 8 to realize the opening and closing of the valve plate. The second wing valve body 7 and the first wing valve plate 6 form a multi-channel structure. By adjusting the angle and position of the valve plate, precise control of the solid particle flow rate is achieved.

[0030] Furthermore, a pressure measuring interface 2 is provided on the feed leg 1, and the pressure measuring interface 2 is used to monitor the pressure change in the feed leg in real time, so as to determine the flow state of the solid particles.

[0031] Furthermore, a first lifting ring 4 and a second lifting ring 5 are installed on the lifting ring bracket 3 to facilitate the lifting and installation of the entire wing valve.

[0032] Furthermore, when the catalyst in the feed leg 1 starts to be discharged, the pneumatic valve 8 controls the first wing valve plate 6 to open, and the catalyst flows out.

[0033] Furthermore, the opening angle of the first wing valve plate 6 increases accordingly with the increase of the discharge volume to accommodate a larger flow rate. When the discharge volume decreases or stops, the pneumatic valve 8 controls the first wing valve plate 6 to gradually close until it is completely closed to prevent gas backflow.

[0034] Furthermore, the angle between the second wing valve body 7 and the first wing valve plate 6 enables the solid particles to be buffered when flowing through the wing valve.

[0035] In summary, the multi-channel wing valve can achieve precise regulation of the solid particle flow rate through precise control of the pneumatic valve and the compressed air pipeline. This precise control not only ensures the stability of the treatment process, but also greatly improves the treatment efficiency. During the catalyst discharge process, as the discharge amount changes, the wing valve plate can automatically adjust the opening and closing angle to ensure that the flow rate matches the discharge amount, avoiding the problem of resource waste or poor treatment effect caused by excessive or too small flow. The multi-channel wing valve adopts a special multi-channel design, so that when the valve plate is closed, an effective isolation layer is formed between the solid particles and the gas, thereby effectively preventing the occurrence of gas backflow. Especially when the discharge amount is reduced or stopped, the wing valve plate can be quickly closed to avoid equipment damage or safety accidents caused by gas backflow. This design not only ensures the safety of the treatment process, but also extends the service life of the equipment. By setting a pressure measurement interface on the material leg, the multi-channel wing valve can monitor the pressure changes in the material leg in real time. Once the pressure fluctuates abnormally, the system can immediately issue an alarm and take corresponding treatment measures to ensure the stability of the treatment process. This real-time monitoring function enables operators to promptly detect and deal with possible problems, avoiding production interruptions or product quality degradation caused by unstable processing. The multi-channel wing valve adopts a modular design, with tight connections between components and compact structure. At the same time, in order to facilitate installation and maintenance, it is also equipped with lifting devices such as lifting ring brackets and lifting rings. These designs make the installation and maintenance process simpler and faster, reducing the labor intensity and maintenance costs of operators. The multi-channel wing valve has a simple structure, easy operation, and significant effect. It is particularly suitable for occasions where precise flow control is required during the solid particle processing process. Whether it is the discharge of catalysts, the transportation of solid particles or other occasions that require precise flow control, the multi-channel wing valve can play its unique advantages. At the same time, due to its strong adaptability and high reliability, it can also be customized and optimized according to specific needs to meet the use requirements in different occasions.
