Description

Technical Field

[0001] This application relates to the field of filling valve technology, and in particular to a drip-proof gravity back-suction structure for filling valves for high-viscosity vinegar. Background Technology

[0002] In the liquid filling sector of the food processing industry, filling high-viscosity vinegars (such as aged vinegar and thick fruit vinegar) has always faced unique challenges. These liquids are several times, even tens of times, more viscous than ordinary white vinegar, exhibiting significantly poorer fluidity and extremely strong adhesion. During the filling process, the vinegar easily adheres to the valve orifice, valve core, and internal flow channel surfaces of the filling valve. After filling is completed, the residual vinegar at the valve orifice slowly drips down under the combined effect of its own gravity and surface tension, resulting in leakage that affects production efficiency and product quality. Existing technologies primarily address this by enhancing mechanical sealing performance or employing pneumatic purging methods.

[0003] Currently, traditional anti-drip structures have problems when dealing with high-viscosity vinegar, such as difficulty in cleaning residual vinegar at the valve orifice and frequent dripping. Due to the poor fluidity of high-viscosity vinegar, conventional back-suction technology cannot recover the residual vinegar at the valve orifice in time, resulting in the residual vinegar slowly dripping down after filling. This not only wastes materials but also contaminates filling equipment and the production environment. In addition, traditional anti-drip technology has a narrow range of applications and cannot be flexibly adjusted according to changes in the viscosity and concentration of vinegar. It is difficult to meet the anti-drip filling requirements of various products such as low-viscosity rice vinegar and high-viscosity aged vinegar at the same time, which seriously affects filling efficiency and product quality. Utility Model Content

[0004] The purpose of this application is to provide a drip-proof gravity back-suction structure for a high-viscosity vinegar filling valve, which can promptly suck the high-viscosity vinegar residue at the valve port into the collection tank, effectively solving the problems of difficult cleaning of residual vinegar and frequent dripping in traditional technology. At the same time, this structure can be adapted to filling vinegar of different viscosities, breaking through the limitations of the application scope of traditional technology, and solving the problems mentioned in the background technology.

[0005] The anti-drip gravity back-suction structure of the high-viscosity vinegar filling valve provided in this application adopts the following technical solution: It includes a valve body, with a valve core assembly disposed on the inner side of the valve body. The valve core assembly includes a valve core body slidably connected to the inner side of the valve body. A back-suction channel is opened on the inner side of the valve core body, and a connecting port is provided on the outer side of the valve body. A connecting pipe is fixedly connected to the outer side of the valve body, and the inner wall of the connecting pipe is connected to the inner wall of the connecting port. The inner wall size of the back-suction channel is adapted to the inner wall size of the connecting port. A feed pipe is fixedly connected to the outer side of the valve body, and a collection box is fixedly connected to the other end of the connecting pipe. The inner wall of the connecting pipe is connected to the inner wall of the collection box. A negative pressure adsorption assembly is disposed on the outer side of the collection box. The negative pressure adsorption assembly includes a second cylinder fixedly connected to the upper side of the collection box. A piston plate is fixedly connected to the output end of the second cylinder, and the piston plate is located inside the collection box. A solenoid valve is fixedly installed at the outlet end of the collection box.

[0006] By adopting the above technical solution, a valve core assembly is set inside the valve body. The back suction channel inside the valve core body cooperates with the connecting pipe, collection box and negative pressure adsorption assembly outside the valve body. After filling, the second cylinder in the negative pressure adsorption assembly drives the piston plate to move up, forming a negative pressure in the collection box. The back suction channel is used to suck the high viscosity vinegar liquid remaining at the valve port into the collection box in time, which effectively solves the problems of difficult cleaning of residual vinegar liquid and frequent dripping in traditional technology, and reduces material waste and equipment pollution.

[0007] Preferably, a first cylinder is fixedly installed on the upper side of the valve body, and the output end of the first cylinder is fixedly connected to the upper side of the valve core body.

[0008] By adopting the above technical solution, the output end of the first cylinder is connected to the valve core body, which can accurately control the sliding of the valve core body in the valve body, ensure the rapid switching between filling and back suction actions, and avoid the accumulation of residual liquid caused by the response delay of traditional mechanical seals.

[0009] Preferably, a first sealing ring is fixedly embedded on the inner side of the valve core body, and the first sealing ring is made of rubber.

[0010] By adopting the above technical solution, the first sealing ring embedded inside the valve core body is made of rubber. When the valve core body and the valve body are in contact, the sealing performance can be effectively enhanced, preventing high-viscosity acetic acid from leaking from the gap between the valve core body and the valve body, and further reducing the occurrence of dripping.

[0011] Preferably, the inner wall of the valve body is conical, and the bottom end of the valve core body is conical, with the bottom shape of the valve core body matching the inner wall shape of the valve body.

[0012] By adopting the above technical solution, the conical fitting design of the inner wall of the valve body and the bottom of the valve core body guides the residual liquid to gather in the back suction channel, improving the recovery efficiency. At the same time, when the filling valve is closed, the conical part at the bottom of the valve core body can fit tightly against the inner wall of the valve body to form a good sealing structure, reducing the residue of high viscosity vinegar at the valve port. In addition, in conjunction with the back suction channel, the anti-drip function is achieved more efficiently.

[0013] Preferably, a rubber sleeve is fixedly connected to the outer side of the piston plate, and the rubber sleeve is made of rubber.

[0014] By adopting the above technical solution, the rubber sleeve on the outside of the piston plate is made of rubber, which can enhance the sealing between the piston plate and the inner wall of the collection box, ensure the stability of the negative pressure generated by the negative pressure adsorption component, make the back suction process more reliable, and ensure the effective recovery of residual vinegar at the valve port.

[0015] Preferably, a retaining ring is fixedly connected to the inner side of the collection box, and the retaining ring is located on the upper side of the connecting pipe.

[0016] By adopting the above technical solution, the retaining ring inside the collection box is located on the upper side of the connecting pipe, which can prevent the piston plate from blocking the connecting pipe during movement, ensuring that the back suction channel is unobstructed, so that the residual vinegar at the valve port can be smoothly sucked into the collection box through the connecting pipe, thus ensuring the stability and effectiveness of the back suction process.

[0017] Preferably, an inspection door is rotatably installed on the outside of the collection box.

[0018] By adopting the above technical solution, the maintenance door panel that is rotatably installed on the outside of the collection box makes it easier for staff to clean and maintain the inside of the collection box, promptly deal with residual vinegar and possible blockages, and ensure the long-term stable operation of the filling valve.

[0019] Preferably, a second sealing ring is fixedly connected to the outer side of the inspection door panel, and the second sealing ring is made of rubber.

[0020] By adopting the above technical solution, the second sealing ring on the outside of the inspection door panel is made of rubber. When the inspection door panel is closed, it can enhance the sealing of the collection box, prevent the leakage of residual vinegar and the emission of odors, and at the same time prevent external impurities from entering and affecting the normal operation of the back suction system.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] This high-viscosity vinegar filling valve features a drip-proof gravity back-suction structure. A valve core assembly is installed inside the valve body. The back-suction channel inside the valve core works in conjunction with the connecting pipe, collection box, and negative pressure adsorption assembly on the outside of the valve body. After filling, the second cylinder in the negative pressure adsorption assembly moves the piston plate upward, creating negative pressure in the collection box. The back-suction channel then promptly draws the residual high-viscosity vinegar from the valve port into the collection box, effectively solving the problems of difficult-to-clean residual vinegar and frequent dripping in traditional technologies. Furthermore, this structure is adaptable to filling vinegar of different viscosities, breaking through the limitations of traditional technologies. The conical fit between the valve core and the valve body, combined with the first sealing ring, rubber sleeve, and second sealing ring, enhances sealing performance and improves the drip-proof effect.

Detailed Implementation

[0030] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail below.

[0031] Example 1: A drip-proof gravity back-suction structure for a high-viscosity vinegar filling valve, comprising a valve body 1, a valve core assembly 2 disposed on the inner side of the valve body 1, the valve core assembly 2 including a valve core body 201 slidably connected to the inner side of the valve body 1, the valve core body 201 sliding upward within the valve body 1, blocking the connecting port and opening the filling channel, then the valve core body 201 moving downward to block the feed pipe 4, thereby closing the filling channel and connecting the back-suction channel 202 and the connecting pipe 5, thereby realizing rapid switching between filling and back-suction functions. A back-suction channel 202 is provided on the inner side of the valve core body 201, and a connecting port is provided on the outer side of the valve body 1. A connecting pipe 5 is fixedly connected to the outer side of the valve body 1, the inner wall of the connecting pipe 5 is connected to the inner wall of the connecting port, the inner wall size of the back-suction channel 202 is adapted to the inner wall size of the connecting port, and a connecting pipe 5 is fixedly connected to the outer side of the valve body 1. The other end of the feed pipe 4 and the connecting pipe 5 is fixedly connected to the collection box 6. The inner wall of the connecting pipe 5 and the inner wall of the collection box 6 are connected. A negative pressure adsorption component 7 is provided on the outside of the collection box 6. The negative pressure adsorption component 7 includes a second cylinder 701 fixedly connected to the upper side of the collection box 6. The output end of the second cylinder 701 is fixedly connected to a piston plate 702. The second cylinder 701 in the negative pressure adsorption component 7 drives the piston plate 702 to move upward, forming a negative pressure in the collection box 6. The high viscosity vinegar liquid remaining at the valve port is sucked into the collection box 6 in time by the back suction channel 202, which effectively solves the problem of difficult cleaning of residual vinegar liquid and frequent dripping in traditional technology, reducing material waste and equipment pollution. The piston plate 702 is located inside the collection box 6. A solenoid valve 11 is fixedly installed at the outlet end of the collection box 6. The solenoid valve 11 controls the opening and closing of the outlet of the collection box 6.

[0032] Example 2: A drip-proof gravity back-suction structure for a high-viscosity vinegar filling valve. A first cylinder 3 is fixedly installed on the upper side of the valve body 1. The output end of the first cylinder 3 is fixedly connected to the upper side of the valve core body 201. The connection between the output end of the first cylinder 3 and the valve core body 201 allows for precise control of the sliding of the valve core body 201 within the valve body 1, ensuring rapid switching between filling and back-suction actions and avoiding residual liquid accumulation caused by response delays in traditional mechanical seals. A first sealing ring 203 is fixedly embedded inside the valve core body 201. The first sealing ring 203 is made of rubber. The rubber material of the first sealing ring 203 embedded inside the valve core body 201 effectively increases the viscosity of the filling valve when the valve core body 201 and the valve body 1 are engaged. The valve body 1 features a strong sealing performance to prevent high-viscosity vinegar from leaking through the gap between the valve core body 201 and the valve body 1, further reducing dripping. The inner wall of the valve body 1 is conical, and the bottom of the valve core body 201 is also conical. The bottom shape of the valve core body 201 matches the inner wall shape of the valve body 1. This conical matching design between the inner wall of the valve body 1 and the bottom of the valve core body 201 guides the residual liquid to gather in the back suction channel 202, improving recovery efficiency. At the same time, when the filling valve is closed, the conical part at the bottom of the valve core body 201 can fit tightly against the inner wall of the valve body 1, forming a good sealing structure and reducing the residue of high-viscosity vinegar at the valve port. Combined with the back suction channel 202, it achieves the anti-drip function more efficiently.

[0033] A rubber sleeve 703 is fixedly connected to the outer side of the piston plate 702. The rubber sleeve 703 is made of rubber. The rubber sleeve 703 on the outer side of the piston plate 702 enhances the sealing between the piston plate 702 and the inner wall of the collection box 6, ensuring the stability of the negative pressure generated by the negative pressure adsorption component 7, making the back suction process more reliable, and ensuring the effective recovery of residual vinegar at the valve port. A retaining ring 8 is fixedly connected to the inner side of the collection box 6. The retaining ring 8 is located on the upper side of the connecting pipe 5. By having the retaining ring 8 on the inner side of the collection box 6 located on the upper side of the connecting pipe 5, it can prevent the piston plate 702 from blocking the connecting pipe 5 during movement, ensuring that the back suction channel 202 is unobstructed, so that the residual vinegar at the valve port can be smoothly sucked in through the connecting pipe 5. The collection box 6 ensures the stability and effectiveness of the back suction process. A maintenance door 9 is rotatably installed on the outside of the collection box 6. The maintenance door 9 rotatably installed on the outside of the collection box 6 facilitates the cleaning and maintenance of the inside of the collection box 6 by the staff, and can deal with residual vinegar and possible blockage problems in a timely manner, ensuring the long-term stable operation of the filling valve. A second sealing ring 10 is fixedly connected to the outside of the maintenance door 9. The second sealing ring 10 is made of rubber. When the maintenance door 9 is closed, it can enhance the sealing of the collection box 6, prevent the leakage of residual vinegar and the emission of odors, and at the same time prevent external impurities from entering and affecting the normal operation of the back suction system.

[0034] The implementation principle of this application embodiment is as follows: When filling high-viscosity vinegar, the valve core body 201 is controlled by the first cylinder 3 to slide upward in the valve body 1. At this time, the connecting port is blocked and the filling channel is opened. The vinegar enters the valve body 1 through the feed pipe 4 to complete the filling. After filling is completed, the first cylinder 3 moves the valve core body 201 downward to block the feed pipe 4, thereby closing the filling channel. At the same time, the connecting port connects with the back suction channel 202. At this time, the conical part at the bottom of the valve core body 201 fits tightly with the inner wall of the valve body 1, forming a good sealing structure, reducing the residue of high-viscosity vinegar at the valve port. Meanwhile, the inclined wall guides the residual liquid to gather in the back suction channel 202, improving the recovery efficiency. Then, the second cylinder 701 moves the piston plate 702 upward, forming a negative pressure in the collection box 6. Since the back suction channel 202 is connected to the connecting pipe 5 and the collection box 6, the high-viscosity vinegar residue at the valve port is sucked into the collection box 6 through the back suction channel 202 under the action of negative pressure. During this process, the retaining ring 8 prevents the piston plate 702 from blocking the connecting pipe 5, ensuring that the back suction channel 202 is unobstructed. At the same time, the rubber sleeve 703, the first sealing ring 203 and the second sealing ring 10 ensure the sealing between the components, ensuring that the back suction process is efficient and stable. When it is necessary to drain the vinegar collected in the collection tank 6, the solenoid valve 11 is opened to control the outlet of the collection tank 6 to open, so that the vinegar inside can be drained out from here. At this time, the maintenance door panel 9 can facilitate the maintenance operation of the components inside the collection tank 6 by the staff, thereby realizing efficient anti-drip filling of high viscosity vinegar.
