[0023] Example 1: It should be noted that, as Figure 7 and 8 As shown, the valve body structure 1000 is typically used in a storage container to store materials, such as dry powder or fluid materials, and to discharge materials from the storage container through the material outlet 2100. The valve body structure 1000 controls the opening or closing of the material outlet 2100. In related technologies, the valve body structure 1000 can only fully open or fully close the material outlet 2100. When the storage container needs to discharge materials, the valve body structure 1000 opens the material outlet 2100. Because the material outlet 2100 is fully open, the materials in the storage container will be rapidly discharged from the material outlet 2100 to the downstream equipment, causing material accumulation in the downstream equipment, resulting in material waste, and in severe cases, damage to the downstream equipment. Therefore, this embodiment provides a valve body structure 1000 to control the material discharge rate and avoid excessive material accumulation in the downstream equipment.

[0024] like Figure 1-6 As shown, this embodiment provides a valve body structure 1000 applied to a storage container, the storage container having a material outlet 2100; the valve body structure 1000 includes a valve seat 100, a valve core 200, and a drive assembly 400; the valve seat 100 is installed on the material outlet 2100 and is connected to the material outlet 2100; the valve core 200 is disposed on the valve seat 100, and a material channel 300 can be formed between the valve core 200 and the valve seat 100; the drive assembly 400 is installed on the valve seat 100; the drive assembly 400 is configured to drive the valve core 200 to move away from or towards the valve seat 100, thereby adjusting the size of the material channel 300 between the valve seat 100 and the valve core 200.

[0025] In this embodiment, the valve body structure 1000 includes a valve seat 100, a valve core 200, and a drive component 420. The valve core 200 and the valve seat 100 cooperate to form a material channel 300 for material flow. The drive component 400 is mounted on the valve seat 100 and can drive the valve core 200 to move away from or towards the valve seat 100. When it is necessary to open the material outlet 2100, the drive component 400 drives the valve core 200 to move away from the valve seat 100, and a material outlet 2100 is formed between the valve seat 100 and the valve core 200 and the storage container. Material is connected to material channel 300. Material in storage container can flow through material outlet 2100 to material channel 300, and then through material channel 300 to downstream equipment. When it is necessary to close material outlet 2100, the drive component 400 drives valve core 200 to move close to valve seat 100 until valve core 200 and valve seat 100 are tightly attached. Material channel 300 between valve core 200 and valve seat 100 is closed, that is, material cannot enter material channel 300 from material outlet 2100, thus closing material outlet 2100. When it is necessary to adjust the output speed of the material, the drive assembly 400 can adjust the size of the material channel 300 between the valve seat 100 and the valve core 200, that is, the drive assembly 400 can adjust the distance between the valve seat 100 and the valve core 200. When it is necessary to increase the output speed of the material, the drive assembly 400 drives the valve core 200 to move away from the valve seat 100, and the distance between the valve core 200 and the valve seat 100 increases, that is, the material channel 300 between the valve seat 100 and the valve core 200 increases. The material channel 300 can accommodate more material, thereby increasing the output speed. The output speed of the material is increased; when it is necessary to reduce the output speed of the material, the valve core 200 is driven to move closer to the valve seat 100 by the drive component 400, the distance between the valve core 200 and the valve seat 100 is reduced, that is, the material channel 300 between the valve seat 100 and the valve core 200 is reduced, and the material channel 300 only allows a small amount of material to pass through, thereby reducing the output speed of the material; in addition, by adjusting the air pressure or air volume of the air bag 421, the movement distance of the valve core 200 is controlled, thereby adjusting the size of the material channel 300 and achieving precise control of the material flow rate.

[0026] The valve body structure 1000 drives the valve core 200 to move away from or near the valve seat 100 through the drive component 400, so as to adjust the size of the material channel 300 between the valve seat 100 and the valve core 200, thereby adjusting the output speed of the material and controlling the output speed of the material to effectively prevent material accumulation in downstream equipment.

[0027] like Figure 4 and 6As shown, the valve seat 100 has a first conical portion 110, and the valve core 200 has a second conical portion 210. The first conical portion 110 and the second conical portion 210 are coaxial; the material channel 300 is formed between the first conical portion 110 and the second conical portion 210.

[0028] In this embodiment, the valve seat 100 has a first conical portion 110, the outer side of which is inclined, and the valve core 200 has a second conical portion 210, the inner side of which is also inclined. The first conical portion 110 is located inside the second conical portion 210, and the first conical portion 110 and the second conical portion 210 are coaxially arranged, that is, the valve seat 100 and the valve core 200 are coaxially arranged, which can ensure that the outer side of the first conical portion 110 and the inner side of the second conical portion 210 are opposite to each other. So that when it is necessary to close the material outlet 2100, the drive assembly 400 can drive the valve core 200 to move closer to the valve seat 100, and the first conical portion 110 can just fit against the second conical portion 210, ensuring that the material channel 300 is closed, thereby realizing the closure of the material outlet 2100 by the valve body structure 1000. Furthermore, the outer side of the first conical portion 110 and the inner side of the second conical portion 210 are arranged opposite each other and are inclined surfaces, which can ensure that the material can flow out smoothly along the inclined surface.

[0029] like Figure 3-6 As shown, the drive assembly 400 includes a support base 410 and a drive member 420; the support base 410 is mounted on the valve seat 100, and the drive member 420 is mounted on the support base 410. The drive member 420 is used to drive the valve core 200 to move away from or towards the valve seat 100, and adjust the distance between the first tapered portion 110 and the second tapered portion 210 to adjust the size of the material channel 300.

[0030] In this embodiment, the support base 410 provides support and a mounting position for the drive component 420, enabling the drive component 420 to smoothly drive the valve core 200 to move. The support base 410 is installed inside the valve seat 100, and the support base 410 and the valve seat 100 are fixedly connected. The drive component 420 is installed on the support base 410, and drives the valve core 200 to move, thereby adjusting the distance between the first conical portion 110 and the second conical portion 210, thus opening or closing the material outlet 2100, or adjusting the size of the material channel 300 to achieve precise adjustment of the material output speed. In some embodiments, the drive component 420 can be a pneumatic drive component 420, such as an airbag 421 or a cylinder, or an electric drive component 420, such as a lifting device driven by a motor or a lead screw module.

[0031] like Figure 3-6As shown, the driving component 420 includes an airbag 421; the airbag 421 has a fixed end 421a and a free end 421b, the fixed end 421a is mounted on the support base 410, and the free end 421b is connected to the valve core 200; the support base 410 is provided with a gas flow channel 411, and the gas flow channel 411 is connected to the airbag 421.

[0032] In this embodiment, the driving component 420 is a pneumatic driving component 420, which includes an airbag 421. The airbag 421 is a flexible rubber capsule filled with a fluid medium such as compressed air, utilizing the compressibility and fluidity of air to achieve an elastic effect. The airbag 421 generally has a fixed end 421a and a free end 421b. The fixed end 421a is the end that fixes the airbag 421 and can be fixedly installed on the support base 410 by bolts. The free end 421b is the expansion end of the airbag 421. That is, when the fluid medium is injected, the free end 421b of the airbag 421 inflates, increasing the height of the free end 421b. When the fluid medium inside the airbag 421 is released, the free end 421b of the airbag 421 contracts, decreasing the height of the free end 421b. The free end 421b of the air bladder 421 is connected to the valve core 200, meaning the valve body moves away from or towards the valve seat 100 under the drive of the free end 421b of the air bladder 421. Specifically, when the air bladder 421 is injected into the fluid medium through the gas flow channel 411, the free end 421b of the air bladder 421 inflates and expands, pushing the valve core 200 upward, that is, the valve core 200 moves away from the valve seat 100, thereby increasing the material channel 300 and improving the material output speed. When the air bladder 421 discharges the fluid medium through the gas flow channel 411, the free end 421b of the air bladder 421 contracts and pulls the valve core 200 downward, that is, the valve core 200 moves closer to the valve seat 100, thereby reducing the material channel 300, decreasing the material output speed, or closing the material outlet 2100.

[0033] Furthermore, the drive component 420 is a pneumatic drive component 420, and the airbag 421 is safer and more reliable to use in harsh environments such as flammable and explosive, dusty, strong magnetic, radiation, and vibration environments. The airbag 421 uses compressed air and does not generate electric sparks, reducing the risk of use in these special environments. Moreover, the airbag 421 can achieve simple stepless speed regulation and torque change by adjusting the speed of the gas medium input into the airbag 421. Since the airbag 421 only needs to be supplied with gas, the component can be made lighter and more suitable for use in industrial equipment that requires compact design, greatly reducing the size and weight of the valve body structure 1000.

[0034] like Figure 3-6As shown, the driving component 420 further includes a driving block 422; the driving block 422 is fixedly connected to the free end 421b of the airbag 421, the valve core 200 is provided with a connecting block 220, and the driving block 422 is fixedly connected to the connecting block 220.

[0035] In order for the airbag 421 to smoothly drive the valve core 200 to move away from or near the valve seat 100, a drive block 422 is fixedly connected to the free end 421b of the airbag 421. The drive block 422 is fixedly connected to the connecting block 220 provided in the valve core 200, so that a rigid connection is formed between the free end 421b of the airbag 421 and the valve core 200. Through the drive block 422 and the connecting block 220, the valve seat 100 and the free end 421b of the airbag 421 can be ensured to move synchronously. Specifically, when the airbag 421 is inflated, the free end 421b expands, driving the drive block 422 to move upward away from the valve seat 100. The drive block 422 pushes the connecting block 220 to make the valve core 200 move upward away from the valve seat 100. When the airbag 421 is deflated, the free end 421b contracts, pulling the drive block 422 downward towards the valve seat 100. The drive block 422 pulls the connecting block 220 to make the valve core 200 move downward towards the valve seat 100. Through the connection of the drive block 422 and the connecting block 220, the valve core 200 moves away from or towards the valve seat 100 under the action of the airbag 421, thereby adjusting the size of the material channel 300.

[0036] like Figure 3-6 As shown, the support base 410 includes a first horizontal support 412, a vertical support 413, and a mounting block 414; one end of the first horizontal support 412 is fixedly connected to the valve seat 100, and one end of the vertical support 413 is fixedly connected to the end of the first horizontal support 412 away from the valve seat 100; the mounting block 414 is fixedly connected to the end of the vertical support 413 away from the first horizontal support 412, and the airbag 421 is fixedly connected to the mounting block 414. 14; The gas flow channel 411 includes a horizontal section 411a and a vertical section 411b; the horizontal section 411a is disposed on the first horizontal support 412, the vertical section 411b is disposed on the vertical support 413, and the horizontal section 411a and the vertical section 411b are connected; the mounting block 414 is provided with a vent 414a, the vent 414a is connected to the vertical section 411b, and the vent 414a is connected to the airbag 421.

[0037] In this embodiment, one end of the first lateral support 412 is fixedly connected to the valve seat 100. Preferably, there are two first lateral supports 412, and the two first lateral supports 412 are located on the same straight line to ensure that they can form a stable support effect on the vertical support 413. One end of the vertical support 413 is fixedly connected to the end of the first lateral support 412 away from the valve seat 100. The vertical support 413 can be stably placed inside the valve seat 100 through the first lateral support 412. The airbag 421 is fixedly installed on the vertical support 413 through the mounting block 414. The vertical support 413 ensures the stable installation of the airbag 421 so that the free end 421b of the airbag 421 can expand or contract, thereby enabling the airbag 421 to drive the valve core 200 to move away from or closer to the valve seat 100. The gas flow channel 411 is used to connect to external equipment (such as a compressor), allowing gaseous medium to be filled into the airbag 421 through the gas flow channel, causing the airbag 421 to inflate, or allowing gas in the airbag 421 to be discharged through the gas flow channel 411, causing the airbag 421 to contract. Specifically, the gas flow channel 411 includes a horizontal section 411a and a vertical section 411b. The horizontal section 411a is located within the first horizontal support 412, and the vertical section 411b is located within the vertical support 413. The mounting block 414 is provided with a vent 414a. Through the horizontal section 411a, the vertical section 411b, and the vent 414a, the airbag 421 is connected to the outside, facilitating the inflation or deflation of the airbag 421 and enabling the expansion or contraction of the airbag 421.

[0038] like Figure 3-6 As shown, the support base 410 also includes an exhaust block 415; one end of the exhaust block 415 is fixedly connected to the mounting block 414, and the other end of the exhaust block 415 extends into the interior of the airbag 421; an exhaust groove 415a is provided inside the exhaust block 415, and the exhaust groove 415a communicates with the vent 414a; an exhaust hole 415b is provided on the periphery of the exhaust block 415, and the airbag 421 communicates with the exhaust groove 415a through the exhaust hole 415b.

[0039] To facilitate the inflation or deflation of the airbag 421, one end of the vent block 415 is fixedly connected to the mounting block 414, and the other end of the vent block 415 extends into the interior of the airbag 421. The vent groove 415a of the vent block 415 is connected to the vent 414a of the mounting block 414, that is, the vent groove 415a is connected to the gas flow channel 411. The airbag 421 is connected to the vent groove 415a through the vent hole 415b on the periphery of the vent block 415. The vent block 415 forms the valve core of the airbag 421. The vent block 415 connects the interior of the airbag 421 and the gas flow channel 411, which facilitates the inflation or deflation of the airbag 421, thereby realizing the expansion or contraction of the airbag 421, driving the valve core 200 to move away from or towards the valve seat 100, adjusting the size of the material channel 300, and realizing precise control of the material output speed.

[0040] like Figure 3-6 As shown, the driving component 420 further includes a reset rod 423 and a reset spring 424; one end of the reset rod 423 is fixedly connected to the free end 421b of the airbag 421, and the other end of the reset rod 423 extends along the interior of the airbag 421 into the exhaust groove 415a of the exhaust block 415; the end of the reset rod 423 away from the free end 421b is slidably connected to the exhaust groove 415a; a first abutting block 423a is provided at the end of the reset rod 423 away from the free end 421b, and a second abutting block 415c is provided in the exhaust groove 415a; the reset spring 424 is sleeved on the reset rod 423, and one end of the reset spring 424 abuts against the first abutting block 423a, and the other end abuts against the second abutting block 415c.

[0041] When it is necessary to reduce the material passage 300, the air bladder 421 is vented, causing it to contract and drive the valve core 200 to move closer to the valve seat 100, thereby reducing the material passage 300. Considering that the air bladder 421 contracts slowly after venting, and the material passage 300 cannot be reduced quickly, in this embodiment, one end of the reset rod 423 is fixedly connected to the free end 421b of the air bladder 421, and the other end of the reset rod 423 extends along the interior of the air bladder 421 into the exhaust groove 415a of the exhaust block 415. The end of the reset rod 423 away from the free end 421b is slidably connected to the exhaust groove 415a, and the reset spring 424 is sleeved on the reset rod 421b. 3. One end of the return spring 424 abuts against the first abutting block 423a, and the other end abuts against the second abutting block 415c. When the airbag 421 is inflated, the free end 421b expands and drives the return rod 423 to slide upward along the exhaust groove 415a, so that the return spring 424 is compressed and the return spring 424 has a rebound force. When it is necessary to reduce the material channel 300, the airbag 421 is vented, and the return rod 423 slides downward along the exhaust groove 415a quickly under the rebound force of the return spring 424, pulling the free end 421b of the airbag 421 to contract quickly, thereby driving the valve core 200 to move smoothly close to the valve seat 100, thereby reducing the material channel 300.

[0042] Furthermore, one end of the reset rod 423 is fixedly connected to the free end 421b of the airbag 421, and the other end of the reset rod 423 extends along the interior of the airbag 421 into the exhaust groove 415a of the exhaust block 415. The end of the reset rod 423 away from the free end 421b is slidably connected to the exhaust groove 415a. The reset rod 423 can only slide up and down along the exhaust groove 415a of the exhaust block 415, so that the free end 421b of the airbag 421 can only expand or contract in the vertical direction, thereby making the valve core 200 move only in the vertical direction, which plays a good guiding role in the movement of the valve core 200.

[0043] like Figure 3 As shown in Figures 6 and 7, the valve body structure 1000 further includes a pneumatic hammer 500, which is installed on the valve core 200; the support base 410 includes a second transverse support 416, one end of which is fixedly connected to the valve seat 100, and the other end is fixedly connected to the vertical support 413; a transverse pipe 416a is provided inside the second transverse support 416, and a vertical pipe 413a is provided in the vertical support 413, with the transverse pipe 416a and the vertical pipe 413a connected in communication; the air inlet end of the pneumatic hammer 500 is connected to the vertical pipe 413a through an air pipe 510.

[0044] In related technologies, when storing powdery materials in storage containers, the materials often form bridging, layering, rat holes, and wall adhesion under the influence of gravity, mechanical compression, or their own stickiness. This can lead to poor material discharge, requiring manual breaking of the arches, posing safety hazards and affecting production continuity.

[0045] In this embodiment, the pneumatic hammer 500 is installed inside the valve core 200. The pneumatic hammer 500 can utilize the principle of aerodynamics to adjust the striking force by adjusting the air supply pressure, and is an impact-type structural device. After the pneumatic hammer 500 is ventilated, it generates high-frequency vibration, which is directly transmitted to the material area in the valve core 200 and the storage container. This effectively breaks down problems such as bridging, stratification, and rat holes caused by the material in the storage container due to compression and viscosity, ensuring that the material falls continuously and smoothly. To supply air to the pneumatic hammer, one end of the second lateral support 416 is fixedly connected to the valve seat 100, and the other end is fixedly connected to the vertical support 413. The second lateral support 416 can further ensure the stability of the support base 410 within the valve seat 100. A lateral pipe 416a is provided inside the second lateral support 416, and a vertical pipe 413a is provided in the vertical support 413. The lateral pipe 416a and the vertical pipe 413a are connected. The air inlet of the pneumatic hammer 500 is connected to the vertical pipe 413a through the air pipe 510. The lateral pipe 416a can be connected to external equipment (such as a compressor). The external equipment provides high-pressure gas, which is output to the pneumatic hammer 500 along the lateral pipe 416a, the vertical pipe 413a, and the air pipe 510, thereby causing the pneumatic hammer 500 to vibrate.

[0046] Example 2: like Figure 7-9 As shown, this embodiment provides a storage container, including a tank 2000 and a valve body structure 1000 as described in Embodiment 1. The tank 2000 has a material outlet 2100; the valve body structure 1000 is detachably installed at the material outlet 2100.

[0047] In this embodiment, the valve body structure 1000 is detachably installed at the material outlet 2100. Specifically, the valve seat 100 of the valve body structure 1000 can be detachably installed at the material outlet 2100 of the tank 2000 by means of bolts. When the material container needs maintenance or replacement, only the connecting bolts need to be removed to remove the entire valve body structure 1000 from the bottom of the tank 2000. After maintenance, it can be quickly reassembled with bolts and put into use. The operation is simple and efficient, which can significantly shorten the downtime for maintenance. Furthermore, through the modular quick-installation design of the valve body structure 1000, it can be assembled with the tank 2000 by bolt connection without the need for modification of the tank 2000. It is compatible with multiple specifications of tank 2000, reducing modification and maintenance costs. When the storage container is in use, compressed air is introduced into the air bladder 421. The air bladder 421 inflates and pushes the valve core 200 upward. The material channel 300 formed between the valve core 200 and the valve seat 100 allows material to flow and be discharged. By adjusting the air pressure or air volume of the air bladder 421, the movement distance of the valve core 200 can be controlled, and the size of the material channel 300 can be adjusted to achieve precise control of the material flow rate. Simultaneously, compressed air is introduced into the pneumatic hammer 500. The pneumatic hammer 500 generates vibration and transmits it to the material in the valve core 200 and the tank 2000. The vibration acts on the material in the tank 2000, breaking up abnormal states such as bridging, stratification, and sticking to the wall, ensuring continuous and smooth material discharge.

[0048] This storage container, through the valve body structure 1000 of Embodiment 1, precisely controls the material flow rate, ensuring continuous and smooth material feeding.

[0049] In some embodiments, a weighing unit, such as a load cell, can be installed downstream of the storage container to accurately weigh and measure the material output controlled by the valve body structure 1000, thereby achieving precise control over the weight of the material discharged from the storage container.

Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the present invention, and all such modifications and substitutions should be covered within the scope of the claims of the present invention.
