[0021] For example, both the valve body and the valve stem are made of metal.

[0022] For example, the valve body is made of a metallic material, and the valve stem is made of an organic material.

[0023] According to an embodiment of this disclosure, a filling device is also provided, including a plurality of filling valves as described above, and a movable plate, wherein each of the plurality of filling valves passes through the movable plate and is detachably fixed to the movable plate; the movable plate is movable along the vertical direction to drive the plurality of filling valves as a whole to be movable along the vertical direction.

[0026] For example, the filling equipment further includes a sterile air delivery pipe, which is airtightly connected to the end of the sterile air guide pipe near the mounting plate; the diameter of the sterile air guide pipe is larger than the diameter of the sterile air delivery pipe.

[0056] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. Based on the described embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0057] Unless otherwise defined, the technical or scientific terms used herein shall have the ordinary meaning as understood by one of ordinary skill in the art to which this disclosure pertains. The terms “first,” “second,” and similar terms used in this patent application specification and claims do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as “comprising” or “including” mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Terms such as “inner,” “outer,” “upper,” and “lower” are used only to indicate relative positional relationships, which may change accordingly when the absolute position of the described object changes.

[0058] The accompanying drawings in this disclosure are not drawn to scale, and the specific dimensions and quantity of each structure can be determined according to actual needs. The drawings described in this disclosure are only structural schematic diagrams.

[0059] According to embodiments of this disclosure, a filling valve is provided for filling raw materials into containers. The raw materials are, for example, food products such as milk, beverages, and vegetable purees. Figure 1A This is a schematic diagram of the filling valve according to an embodiment of the present disclosure. Figure 2A This is a second structural schematic diagram of a filling valve according to an embodiment of the present disclosure. Figure 3A This is a schematic diagram of the filling valve according to an embodiment of the present disclosure, and Figure 5A This is a schematic diagram of the structure of a filling valve according to an embodiment of the present disclosure. Figure 4 See also Figure 1A , Figure 2A , Figure 3A and Figure 5AThe filling valve according to an embodiment of the present disclosure includes: a valve body 100 having a valve cavity 110 and an inlet 111 and an outlet 112 communicating with the valve cavity 110, the valve cavity 110 extending in a vertical direction D, and the outlet 112 located at the lower end of the valve body 100 in the vertical direction D; and a valve stem 120 installed in the valve cavity 110; wherein the valve stem 120 is movable relative to the valve body 100 in the vertical direction D, and the valve body 100 is movable in the vertical direction D. The filling valve also includes: a first isolating element 130, disposed within the valve cavity 110, dividing the valve cavity 110 into a first part 110-1 and a second part 110-2, with the inlet 111 and outlet 112 located in the second part 110-2; and a second isolating element 140, disposed outside the valve body 100, dividing the valve body 100 into a first part 100-1 and a second part 100-2, with the outlet 112 located in the second part 100-2.

[0060] For example, raw materials enter valve chamber 110 through inlet 111 and exit valve chamber 110 through outlet 112 and are filled into containers (e.g., Figure 8A Container 520 shown). Figure 1A , Figure 2A , Figure 3A and Figure 5A In the middle, the pipeline connected to the feed inlet 111 is the pipeline for conveying raw materials.

[0061] According to an embodiment of this disclosure, the valve stem 120 is movable relative to the valve body 100 in the vertical direction D. For example, if the valve stem 120 moves downward relative to the valve body 100 in the vertical direction D, the valve stem 120 closes the discharge port 112, preventing the raw material from leaving the valve chamber 110 through the discharge port 112, and filling stops. Alternatively, if the valve stem 120 moves upward relative to the valve body 100 in the vertical direction D, the valve stem 120 no longer closes the discharge port 112, and the raw material leaves the valve chamber 110 through the discharge port 112 and enters the container, allowing filling to proceed. During the vertical movement of the valve stem 120 up and down in the vertical direction D, bacteria may be introduced into the raw material that has already entered the valve cavity 110 (for example, when the valve stem 120 moves upward, the upper end of the valve stem 120 moves out of the valve cavity 110 and carries bacteria, and then when the valve stem 120 moves downward, the bacteria enter the valve cavity 110 along with the upper end of the valve stem 120), causing raw material contamination; in order to avoid this situation, the filling valve according to the embodiment of the present disclosure includes a first isolation member 130, which is disposed in the valve cavity 110 to isolate the valve cavity 110 into a first part 110-1 and a second part 110-2, with the inlet 111 and the outlet 112 located in the second part 110-2. Since the inlet 111 and outlet 112 are located in the second part 110-2, the raw material entering the valve chamber 110 will be located in the second part 110-2 of the valve chamber 110. By providing the first isolator 130, the first part 110-1 of the valve chamber 110 can be isolated from the raw material located in the second part 110-2 of the valve chamber, ensuring that bacteria in the first part 110-1 of the valve chamber 110 will not reach the raw material in the second part 110-2 of the valve chamber 110. The first isolator 130 ensures the sterility of the second part 110-2 of the valve chamber 110, so that even if the valve stem 120 moves up and down, it will not cause any contamination to the raw material entering the valve chamber 110. For example, in the vertical direction, the first part 110-1 is at least partially located above the second part 110-2. For example, the first isolator 130 isolates the inlet 111 and outlet 112 from the upper region of the valve chamber 110, thereby isolating all raw materials that have entered the valve chamber 100 from the upper region of the valve chamber 110. By providing the first isolator 130, the upper region of the valve chamber 110 is isolated from the lower region of the valve chamber 110, including the inlet 111 and outlet 112, ensuring the sterility of the lower region of the valve chamber 110, including the inlet 111 and outlet 112, so that even if the valve stem 120 moves up and down, it will not cause any contamination to the raw materials entering the valve chamber 110.

[0062] It should be noted that, in this embodiment of the present disclosure, the first isolator 130 "isolates" the valve cavity 110 into a first part 110-1 and a second part 110-2 to the extent that bacteria reaching the first part 110-1 cannot enter the second part 110-2. Therefore, bacteria in the first part 110-1 will not contaminate the raw materials in the second part 110-2, ensuring the achievement of aseptic filling.

[0063] According to an embodiment of this disclosure, the valve body 100 is movable in the vertical direction D. This allows the distance between the outlet 112 of the filling valve and the container to be adjusted to the optimal distance for the raw material to enter the container, improving the flexibility and controllability of the filling valve according to this disclosure. During the vertical movement of the valve body 100, bacteria may be carried to the outlet 112, causing raw material contamination. To avoid this, the filling valve according to this disclosure includes a second isolator 140, which is disposed outside the valve body 100 to separate the valve body 100 into a first part 100-1 and a second part 100-2, with the outlet 112 located in the second part 100-2. Since the outlet 112 is located in the second part 100-2, the second isolator 140 can separate the first part 100-1 of the valve body 100 from the outlet 112, ensuring that bacteria in the first part 100-1 of the valve body 100 do not reach the outlet 112. The second isolator 140 ensures sterility at the outlet 112, preventing contamination of the raw material to be filled into the container even if the valve body 100 moves up or down. For example, in the vertical direction, the first portion 100-1 is at least partially located above the second portion 100-2. For example, the second isolator 140 isolates the area of ​​the valve body 100, excluding the outlet 112, from the external environment. Here, "external environment" refers to the area referred to below. Figure 8A The described sterile chamber. By providing a second isolation element 140, the outlet 112 is exposed to the sterile chamber, while the area of ​​the valve body 100 other than the outlet 112 is isolated from the sterile chamber, ensuring the sterility of the outlet 112 location, so that even if the valve body 100 moves up and down, it will not cause any contamination to the raw material to be filled into the container.

[0064] It should be noted that, in this embodiment of the disclosure, the second isolator 140 "isolates" the valve body 100 into a first part 100-1 and a second part 100-2 to the extent that bacteria reaching the first part 100-1 cannot enter the second part 100-2. Therefore, bacteria in the first part 100-1 will not contaminate the raw material at the outlet 112, ensuring the realization of aseptic filling.

[0065] According to embodiments of this disclosure, the valve stem 120 is movable relative to the valve body 100 in the vertical direction D, and the valve body 100 is also movable in the vertical direction D. This means the filling valve according to embodiments of this disclosure has two independently controllable strokes, making it more flexible and versatile for various applications. It can be used to fill different types of raw materials into containers of different sizes, meeting diverse user needs. Furthermore, considering the risk of introducing bacteria and contaminating raw materials in both individual strokes, the filling valve according to embodiments of this disclosure also includes a first isolation element 130 and a second isolation element 140, ensuring that aseptic filling can still be achieved even with a dual-stroke configuration.

[0066] The present invention does not limit the specific structure of the first isolation member 130 and the second isolation member 140, as long as they can meet the isolation requirements described above.

Figure 1B and subsequent Figure 1C , Figure 2B , Figure 3B and Figure 5B These simplified diagrams, for the purpose of aiding understanding, depict the relevant components in a very minimalist manner, omitting the specific structures of each component. See also Figure 1A and Figure 1B For example, the first isolation element 130 is a sterilization gas barrier; the valve body 100 has an inlet 131 and an outlet 132 communicating with the valve cavity 110. Sterilization gas enters the valve cavity 110 from the inlet 131 and leaves the valve cavity 110 from the outlet 132 to form a sterilization gas barrier within the valve cavity 110; in the vertical direction D, both the inlet 131 and the outlet 132 are higher than the feed inlet 111; and in the vertical direction D, the downward stroke of the valve stem 120 is no greater than the size of the sterilization gas barrier. In this way, the second part 110-2 of the valve cavity 110 remains a sterile area, and even if the valve stem 120 moves up and down, bacteria from the first part 110-1 of the valve cavity 110 will not be carried into the second part 110-2 of the valve cavity 110, ensuring the sterility of the second part 110-2 of the valve cavity 110 and the raw materials contained therein. Furthermore, using a sterilizing gas barrier as the first isolation element 130 is cost-effective and causes minimal damage to the raw materials. For example, the sterilizing gas can be any gas with sterilizing properties; this disclosure does not limit the specific type of sterilizing gas. For example, the sterilizing gas can be high-temperature steam, vaporized hydrogen peroxide, etc.

[0068] Furthermore, according to an embodiment of this disclosure, the sterilizing gas is high-temperature steam; and in the vertical direction D, the inlet 131 is higher than the outlet 132. High-temperature steam is readily available, environmentally friendly, and inexpensive. For example, the temperature of the high-temperature steam is greater than or equal to 130 degrees Celsius. When the sterilizing gas is high-temperature steam, setting the inlet 131 higher than the outlet 132 in the vertical direction D allows the outlet 132 to also serve as a condensate drain outlet, conveniently discharging the condensate generated during the flow of high-temperature steam (e.g., condensate formed when high-temperature steam hits the wall of the valve cavity 110) from the valve cavity 110, preventing the condensate from falling into the raw materials inside the valve cavity 110.

[0069] Figure 2B yes Figure 2A A simplified schematic diagram of part A3 of the filling valve. See also Figure 2A and Figure 2B For example, the first isolation element 130 is a first retractable sleeve, fitted onto the valve stem 120 and retractable in the vertical direction D; the first retractable sleeve in the vertical direction D includes an upper end 130U and a lower end 130L, the upper end 130U is fixed to the wall of the valve cavity 110, and the lower end 130L is fixed to the valve stem 120; in the vertical direction D, the upper end 130U is higher than the feed inlet 111. See also Figure 2B As the valve stem 120 moves upward in the vertical direction D, the first telescopic sleeve retracts; as the valve stem 120 moves downward in the vertical direction D, the first telescopic sleeve extends. Thus, the first part 110-1 and the second part 110-2 of the valve cavity 110 are always isolated from each other by the first isolator 130, ensuring the sterility of the second part 110-2 of the valve cavity 110. For example, in the vertical direction D, the lower end 130L is also higher than the feed inlet 111, which can prevent the first telescopic sleeve from trapping part of the raw material (e.g., particles in the raw material) during extension and retraction.

[0070] Figure 3B yes Figure 3A A simplified schematic diagram of part A4 of the filling valve. See also Figure 3A and Figure 3BFor example, the first isolation element 130 includes a first sterilization gas barrier 130a and a second sterilization gas barrier 130b; the valve body 100 has a first air inlet 131a and a first air outlet 132a communicating with the valve cavity 110, the first sterilization gas enters the valve cavity 110 from the first air inlet 131a and leaves the valve cavity 110 from the first air outlet 132a to form the first sterilization gas barrier 130a in the valve cavity 110; the valve body 100 has a second air inlet 131b and a second air outlet 132b communicating with the valve cavity 110, the second Sterilizing gas enters valve chamber 110 through second inlet 131b and exits valve chamber 110 through second outlet 132b to form a second sterilizing gas barrier 130b within valve chamber 110. In the vertical direction D, the first inlet 131a, the first outlet 132a, the second inlet 131b, and the second outlet 132b are all higher than the feed inlet 111. Furthermore, in the vertical direction D, the downward stroke of valve stem 120 is not greater than the sum of the dimensions of the first sterilizing gas barrier 130a and the second sterilizing gas barrier 130b. In this way, the second part 110-2 of the valve cavity 110 remains a sterile area. Even if the valve stem 120 moves up and down, bacteria in the area of ​​the valve cavity 110 above the first isolator 130 (i.e., the first part 110-1) will not be carried into the area of ​​the valve cavity 110 below the first isolator 130 (i.e., the second part 110-2), ensuring the sterility of the raw materials in the valve cavity 110. For example, the first sterilizing gas is different from the second sterilizing gas. The combination of the two can stably and effectively eliminate various bacteria and improve the overall sterilization performance of the first sterilizing gas barrier 130a and the second sterilizing gas barrier 130b. For example, along the vertical direction D1, the first sterilizing gas in the upper first sterilizing gas barrier 130a is vaporized hydrogen peroxide, and the second sterilizing gas in the lower second sterilizing gas barrier 130b is high-temperature steam.

[0071] and Figure 2B Compared to the case where the first isolation element 130 is the first retractable sleeve, Figure 1B and Figure 3B Using a sterile gas barrier as the first isolation element 130 can achieve the following beneficial effects: (1) When the raw material to be filled into the container contains particles, the first telescopic sleeve is prone to trapping particles during its extension and retraction, thereby affecting the stroke of subsequent extension and retraction movements. Furthermore, the extension and retraction movements of the first telescopic sleeve may cause particle breakage, affecting the quality and uniformity of the raw material to be filled into the container. Using a sterile gas barrier as the first isolation element 130 will not have the above problems; (2) Using a sterile gas barrier as the first isolation element 130 will save more space, facilitate the setting of other components, and make the overall structure of the filling valve more compact; (3) Using a sterile gas barrier as the first isolation element 130 is easier to implement, while using a first telescopic sleeve as the first isolation element 130 may increase the assembly complexity.

[0072] Figure 1C yes Figure 1A A simplified schematic diagram of part A2 of the filling valve. See also Figure 1A and Figure 1C For example, the filling valve according to an embodiment of this disclosure further includes a mounting plate 300, wherein the second isolation member 140 is a second retractable sleeve, sleeved on the valve body 100 and retractable in the vertical direction D; and the second retractable sleeve in the vertical direction D includes an upper end 140U and a lower end 140L, the upper end 140U being fixed to the mounting plate 300, and the lower end 140L being fixed to the lower end of the valve body 100. See also Figure 1C As the valve body 100 moves upward in the vertical direction D, the second telescopic sleeve retracts; as the valve body 100 moves downward in the vertical direction D, the second telescopic sleeve extends. Thus, the first part 100-1 and the second part 100-2 of the valve body 100 are always isolated from each other by the second isolator 140, ensuring sterility at the outlet 112. As described below, the mounting plate 300 and the guide plate 500 are respectively constructed as the top and bottom walls of the sterile chamber SC. In this case, the second isolator 140 is located within the sterile chamber SC, ensuring sterility at the outlet 112. The second isolator 140 can fulfill its function without occupying too much space.

[0073] Figure 4 This is a cross-sectional schematic diagram of the double-shell connector in a filling valve according to an embodiment of the present disclosure. See also... Figure 1A , Figure 2A , Figure 3A as well as Figure 4 For example, the filling valve according to an embodiment of the present disclosure further includes a double-shell connector 160, which includes an inner shell 161 sleeved on the valve body 100 and an outer shell 162 sleeved on the inner shell 161. In the vertical direction D, the double-shell connector 160 includes an upper end and a lower end. The upper end of the double-shell connector 160 is fixed to the mounting plate 300, and the upper end 140U of the second telescopic sleeve at the lower end of the double-shell connector 160 is clamped and fixed between the inner shell 161 and the outer shell 162. Compared to directly fixing the upper end 140U of the second telescopic sleeve to the mounting plate 300, in the case of setting the double-shell connector 160, the double-shell connector 160 is fixed to the mounting plate 300, and then the upper end 140U of the second telescopic sleeve is connected to the double-shell connector 160. This reduces the assembly difficulty of the second telescopic sleeve, thereby fixing the second telescopic sleeve more stably, and making the implementation of the second isolator 140 simpler and more stable.

See also Figure 5A and Figure 5BAccording to an embodiment of the present disclosure, the filling valve further includes: a mounting plate 300, and an air chamber housing 150 disposed below the mounting plate 300 and fixed to the mounting plate 300 in the vertical direction D, wherein the second isolation member 140 is another sterilization air barrier; the air chamber housing 150 is sleeved on the valve body 100 and together with the valve body 100 defines an air chamber, the air chamber housing 150 has another air inlet 151 and another air outlet 152, sterilization gas enters the air chamber from the other air inlet 151 and leaves the air chamber from the other air outlet 152 to form the other sterilization air barrier in the air chamber; in the vertical direction D, the valve body 100 is movable relative to the air chamber housing 150; in the vertical direction, the downward movement of the valve body 100 is not greater than the size of the other sterilization air barrier. In this way, the second part 100-2 of the valve body 100 remains a sterile area. Even if the valve body 100 moves up and down, bacteria located in the first part 100-1 of the valve body 100 will not be carried into the second part 100-2 of the valve body 100, ensuring the sterility of the outlet 112. Furthermore, using a sterilizing gas barrier as the second isolation element 140 saves space, is easy to implement, and is low in cost. For example, the sterilizing gas can be any gas with sterilizing properties; this disclosure does not limit the specific type of sterilizing gas. For example, the sterilizing gas can be high-temperature steam, vaporized hydrogen peroxide, etc.

The second sterilizing gas enters the valve chamber 110 through the second inlet 131b and exits the valve chamber 110 through the second outlet 132b to form a second sterilizing gas barrier 130b within the valve chamber 110; in the vertical direction D, the first inlet 131a, the first outlet 132a, the second inlet 131b, and the second outlet 132b are all higher than the feed inlet 111; and in the vertical direction D, the downward stroke of the valve stem 120 is not greater than the sum of the dimensions of the first sterilizing gas barrier 130a and the second sterilizing gas barrier 130b; see continue.

[0079] For example, Figure 1B , Figure 2B and Figure 3B The first isolation element 130 shown can all be with Figure 5B The second spacer 140 shown cooperates with a filling valve according to an embodiment of the present disclosure. As an example, Figure 5A The filling valve combination Figure 1B The first isolation component 130 and Figure 5BThe second isolation element 140. See also Figure 5A In the filling valve according to an embodiment of this disclosure, the first isolation element 130 is a sterilization gas barrier; the valve body 100 has an inlet 131 and an outlet 132 communicating with the valve cavity 110, and sterilization gas enters the valve cavity 110 from the inlet 131 and leaves the valve cavity 110 from the outlet 132 to form a sterilization gas barrier within the valve cavity 110; in the vertical direction D, both the inlet 131 and the outlet 132 are higher than the feed inlet 111; in the vertical direction D, the downward stroke of the valve stem 120 is not greater than the size of the sterilization gas barrier; see also... Figure 5A According to an embodiment of this disclosure, the filling valve further includes: a mounting plate 300, and an air chamber housing 150 disposed below the mounting plate 300 and fixed to the mounting plate 300 in the vertical direction D. The second isolation member 140 is another sterilization gas barrier. The air chamber housing 150 is sleeved on the valve body 100 and together with the valve body 100 defines an air chamber. The air chamber housing 150 has another air inlet 151 and another air outlet 152. Sterilization gas enters the air chamber from the other air inlet 151 and exits the air chamber from the other air outlet 152 to form the other sterilization gas barrier within the air chamber.

[0080] Figure 6A This is a partial structural diagram of the filling valve at the discharge port according to an embodiment of the present disclosure. See also... Figure 6AIn the filling valve according to an embodiment of the present disclosure, the lower end of the valve stem 120 has a first conical surface 120S, and the discharge port 112 has a second conical surface 112S. When the first conical surface 120S is in contact with the second conical surface 112S, the discharge port 112 is closed. The valve body 100 includes a detachable main body 101 and a bottom cover 102. The bottom cover 102 is fixed to the main body 101 to clamp and fix the lower end 140L of the second telescopic sleeve between the main body 101 and the bottom cover 102. The joint S1 between the main body 101 and the bottom cover 102 extends to intersect with the second conical surface 112S. The filling valve has a first sealing ring R1 embedded in the second conical surface 112S, and the first sealing ring R1 is disposed at the position where the joint S1 intersects with the second conical surface 112S. To stably fix the lower end 140L of the second telescopic sleeve to the valve body 100, in this embodiment, the valve body 100 includes a detachable main body 101 and a bottom cover 102. After the bottom cover 102 is fixed to the main body 101, the lower end 140L of the second telescopic sleeve can be stably clamped and fixed between the main body 101 and the bottom cover 102. In this embodiment, the management of all gaps in the valve body 100 must also be very strict to prevent bacteria from entering the valve cavity 110 through the gaps and causing raw material contamination. See also Figure 6A The first sealing ring R1 is positioned at the intersection of the seam S1 and the second conical surface 112S, sealing the seam S1 to prevent bacteria from entering the valve cavity 110 through the seam S1, thus ensuring aseptic filling. Further, see... Figure 6A The first sealing ring R1 is embedded in the second conical surface 112S. Typically, the sealing ring is made of organic material. In this case, embedding the first sealing ring R1 in the second conical surface 112S utilizes the flexibility of the organic material to improve the sealing performance between the first conical surface 120S and the second conical surface 112S, thus enabling a more stable sealing of the outlet 112 when it needs to be sealed. For example, the first sealing ring R1 can also be embedded in the first conical surface 120S; however, embedding the first sealing ring R1 in the second conical surface 112S is simpler to assemble and easier to maintain.

[0081] Figure 6B This is a partial structural diagram of the filling valve at the discharge port according to an embodiment of the present disclosure. See also... Figure 6BIn the filling valve according to an embodiment of the present disclosure, the lower end of the valve stem 120 has a first conical surface 120S, and the discharge port 112 has a second conical surface 112S. The discharge port 112 is closed when the first conical surface 120S is in contact with the second conical surface 112S. The valve body 100 includes a detachable main body 101 and a bottom cover 102. The bottom cover 102 is fixed to the main body 101 to clamp and fix the lower end 140L of the second telescopic sleeve between the main body 101 and the bottom cover 102. The joint S1 between the main body 101 and the bottom cover 102 extends so as not to intersect with the second conical surface 112S. The filling valve has a second sealing ring R2, which is disposed at the end of the joint S1 away from the second isolator 140. The filling valve also has a third sealing ring R3, which is embedded in the first conical surface 120S. Figure 6B After the bottom cover 102 is fixed to the main body 101, the lower end 140L of the second telescopic sleeve can be stably clamped and fixed between the main body 101 and the bottom cover 102. Figure 6B In the middle, the joint S1 between the main body 101 and the bottom cover 102 extends so as not to intersect with the second conical surface 112S; and with Figure 6A compared to, Figure 6B In this structure, the seam S1 cannot extend into the valve cavity 110, thus better preventing bacteria from entering the valve cavity 110 via the seam S1. The second sealing ring R2 is positioned at the end of the seam S1 furthest from the second isolator 140 to seal the seam S1 and prevent bacterial growth within it. Additionally, in Figure 6B In this case, compared to embedding the third sealing ring R3 on the second conical surface 112S, embedding the third sealing ring R3 on the first conical surface 120S is easier to achieve.

[0082] Figure 6C This is a partial structural diagram of the filling valve at the discharge port according to an embodiment of the present disclosure. See also... Figure 6CIn the filling valve according to an embodiment of the present disclosure, the lower end of the valve stem 120 has a first conical surface 120S, and the discharge port 112 has a second conical surface 112S. When the first conical surface 120S is in contact with the second conical surface 112S, the discharge port 112 is closed. The valve body 100 includes a detachable main body 101 and a bottom cover 102. The bottom cover 102 is fixed to the main body 101 to clamp and fix the lower end 140L of the second telescopic sleeve between the main body 101 and the bottom cover 102. The joint S1 between 02 extends so as not to intersect with the second conical surface 112S; the filling valve has a second sealing ring R2, which is disposed at the end of the joint S1 away from the second isolator 140; the valve stem 120 includes a metal body 121 and an organic ring 122 sleeved on the lower end of the metal body 121, the lower end face of the organic ring 122 forming a first conical surface 120S; the filling valve also has a fourth sealing ring R4, which is disposed between the organic ring 122 and the metal body 101 in the vertical direction D. Figure 6B The same, in Figure 6C In this configuration, after the bottom cover 102 is fixed to the main body 101, the lower end 140L of the second telescopic sleeve can be stably clamped and fixed between the main body 101 and the bottom cover 102. Furthermore, the seam S1 cannot extend to the valve cavity 110 to better prevent bacteria from entering the valve cavity 110 through the seam S1, and the second sealing ring R2 seals the seam S1 to prevent bacterial growth in the seam S1. Additionally, in Figure 6C In this design, the valve stem 120 includes a metal body 121 and an organic ring 122 fitted onto the lower end of the metal body 121. The lower end face of the organic ring 122 forms a first conical surface 120S. This allows for improved sealing performance between the first conical surface 120S and the second conical surface 112S by utilizing the flexibility of the organic material used to make the organic ring, thereby enabling a more stable sealing of the outlet 112 when it needs to be sealed. For example, the organic ring is made of polyetheretherketone (PEEK). Furthermore, in... Figure 6C In the filling valve, there is also a fourth sealing ring R4, which is disposed between the organic ring 122 and the metal body 101 in the vertical direction D; by providing the fourth sealing ring R4, the organic ring 122 and the metal body 101 can be assembled together more tightly.

[0083] Furthermore, for example, see Figure 6A , Figure 6B and Figure 6CAccording to an embodiment of this disclosure, the filling valve further includes a fifth sealing ring R5, wherein the surface of the bottom cover portion 102 facing the main body portion 101 has a groove 102G, and the lower end 140L of the second telescopic sleeve is embedded in the groove 102G; in the vertical direction D, the fifth sealing ring R5 is disposed between the surface of the main body portion 101 facing the bottom cover portion 102 and the lower end 140L of the second telescopic sleeve, and is clamped and fixed together with the lower end 140L of the second telescopic sleeve between the main body portion 101 and the bottom cover portion 102. The groove 102G helps to fix the lower end 140L of the second telescopic sleeve more stably; the fifth sealing ring R5 allows the main body portion 101 and the bottom cover portion 102 to be fitted together more tightly and seals the end of the joint S1, preventing bacteria from growing in the joint S1.

[0084] For example, see Figure 6A , Figure 6B and Figure 6C The filling valve according to an embodiment of this disclosure further includes: an airflow channel 123 disposed within the valve stem 120 and extending through the valve stem 120 in the vertical direction D. During the process of filling raw materials into the container, there may be situations where the container is not fully opened (e.g., for...). Figure 8A The container 520 shown is a sheet-like plastic container (its two opposing inner surfaces are easily adhered together), which can prevent filling from proceeding smoothly. To prevent the container from not opening sufficiently, the filling valve according to this embodiment of the present disclosure is provided with an airflow channel 123 that passes through the valve stem 120. Before or during filling, gas is blown into the container through the airflow channel 123 to fully open the container and ensure smooth filling. For example, the gas blown into the container through the airflow channel 123 is a food-grade safe gas, such as nitrogen.

[0085] Figure 7 This is a structural schematic diagram of the gas delivery pipe and connector in a filling valve according to an embodiment of the present disclosure. See also... Figure 7 According to an embodiment of this disclosure, the filling valve further includes a gas supply pipe 170 and a connector 180; the connector 180 has a first end 180U and a second end 180L opposite to each other, and has a channel 180C extending from the first end 180U to the second end 180L through the connector 180; the cross section of the first end 180U perpendicular to the vertical direction D is smaller than the cross section of the second end 180L perpendicular to the vertical direction D; the gas supply pipe 170 is airtightly connected to the first end 180U of the connector 180; the channel 180C of the connector 180 is aligned with the airflow channel 123, and the second end 180L of the connector 180 is airtightly connected to the valve stem 120. By setting... Figure 7The connector 180 shown allows for easy and airtight connection between the gas supply pipe 170 and the gas flow channel 123, enabling the delivery of gas to the flow channel 123. The cross-section of the first end 180U perpendicular to the vertical direction D is smaller than that of the second end 180L perpendicular to the vertical direction D, facilitating the connection or removal of the gas supply pipe 170 from the valve stem 120 as needed. For example, the second end 180L of the connector 180 can be connected to the valve stem 120 using rivets; or a sealing ring can be provided at the connection point between the second end 180L of the connector 180 and the valve stem 120 to ensure an airtight connection.

[0086] For example, in the filling valve according to an embodiment of the present disclosure, both the valve body 100 and the valve stem 120 are made of a metal material. For example, the metal material is stainless steel. Using metal materials to manufacture mechanical parts such as the valve body 100 and the valve stem 120 involves mature processing technology, low processing difficulty, and low cost.

[0087] For example, in the filling valve according to an embodiment of the present disclosure, the valve body 100 is made of a metal material, and the valve stem 120 is made of an organic material. For example, the metal material is stainless steel. For example, the organic material is polyetheretherketone (PEEK). In this case, the first conical surface 120S can fit more tightly with the second conical surface 112S, improving the sealing performance of the valve stem 120 to the outlet 112.

[0088] According to embodiments of this disclosure, a filling apparatus is also provided. Figure 8A This is a schematic diagram of a filling apparatus according to an embodiment of the present disclosure. See also... Figure 8A The filling apparatus 1000 according to an embodiment of this disclosure includes a plurality of filling valves as described above, and a movable plate 200, wherein each of the plurality of filling valves passes through the movable plate 200 and is detachably fixed to the movable plate 200; the movable plate 200 is movable in the vertical direction D to drive the plurality of filling valves as a whole to be movable in the vertical direction D. Figure 8A The diagram shows the valve body 100 of the filling valve, and two rows of filling valves are shown as an example. By providing a movable plate 200 that can move along the vertical direction D, the movement of the movable plate 200 can drive multiple filling valves as a whole along the vertical direction D, thereby ensuring the consistency of movement of multiple filling valves, which is beneficial for large-scale filling. In addition, the movement of one movable plate 200 can drive multiple filling valves, which makes the structure simpler, more concise, and space-saving compared to setting a separate drive mechanism for each filling valve.

[0089] For example, see continue. Figure 8AThe filling apparatus 1000 according to an embodiment of this disclosure further includes a mounting plate 300, a perforated plate 400, and a sterile air guide pipe 610. In the vertical direction D, the mounting plate 300 is disposed below the movable plate 200, the perforated plate 400 is disposed below the mounting plate 300, and the sterile air guide pipe 610 is disposed between the mounting plate 300 and the perforated plate 400. Each of a plurality of filling valves passes through the mounting plate 300; each of the plurality of filling valves passes through the perforated plate 400, and the perforated plate 400 has a plurality of through holes penetrating the perforated plate 400 in the vertical direction D; the sterile air guide pipe 610 extends in the vertical direction D and has a plurality of sterile air guide ports on its sidewalls. As described above, the upper end 140U of the second retractable sleeve is connected to the mounting plate 300. As described above, the air chamber housing 150 is connected to the mounting plate 300. The perforated plate 400 has multiple through holes extending through the perforated plate 400 in the vertical direction D. Figure 8A The small black dots at position 600 of the perforated plate represent through holes. Multiple sterile air inlets are located on the side wall of the sterile air guide tube 610. Figure 8A The small black dot on the side wall of the aseptic air guide tube 610 represents the aseptic air guide port. Aseptic air is delivered from the aseptic air guide tube 610 into the aseptic chamber as described below and diffuses. Then, under the guiding action of multiple through holes in the perforated plate, it is dispersed and reaches the discharge ports 112 of multiple filling valves, maintaining the asepticity of the aseptic chamber and the asepticity at the discharge port 112, thereby ensuring the realization of aseptic filling.

[0090] Figure 8B This is a simplified schematic diagram of the bottom wall of the aseptic air guide tube in a filling apparatus according to an embodiment of the present disclosure. For example, see... Figure 8B The bottom wall 610L of the sterile air guide duct 610 near the perforated plate 400 is a basically closed structure with only one opening 610H. For example, this opening 610H is used to guide any condensate that may form. To ensure that the sterile air diffuses over a wider area, multiple sterile air inlets are provided on the sidewall of the sterile air guide tube 610 as described above. If multiple sterile air inlets are also provided on the bottom wall 610L of the sterile air guide tube 610 near the perforated plate 400, the diffusion range of the sterile air flowing out from the bottom wall 610L would be very limited. Therefore, in order to concentrate the sterile air flowing out from the multiple sterile air inlets on the sidewall of the sterile air guide tube 610 and diffuse it over a wider area, in this embodiment of the present disclosure, the bottom wall 610L of the sterile air guide tube 610 does not have sterile air inlets. The bottom wall 610L only has one opening 610H to guide any condensate that may form, so the bottom wall 610L of the sterile air guide tube 610 is essentially closed. For example, to better guide any condensate that may form, the opening 610H is located at the center of the bottom wall 610L.

[0091] Further, see also Figure 8AThe filling equipment according to an embodiment of this disclosure further includes a sterile air delivery pipe 620, which is airtightly connected to the end of a sterile air guide pipe 610 near the mounting plate 300; the diameter of the sterile air guide pipe 610 is larger than the diameter of the sterile air delivery pipe 620. The sterile air guide pipe 610 is located in a sterile chamber as described below, and its larger diameter greatly facilitates the diffusion of sterile air to all locations within the sterile chamber, ensuring the sterility of the chamber.

[0092] Further, see also Figure 8A The filling device according to the present disclosure also includes a guide plate 500, wherein the guide plate 500 is disposed below the perforated plate 400 in the vertical direction D, the mounting plate 300 and the guide plate 500 are respectively constructed as the top wall and bottom wall of the sterile chamber SC, and the sterile air guide pipe 610 continuously introduces sterile air into the sterile chamber SC; the guide plate 500 has a strip opening 510, which is located directly below the outlet 112 of the filling valve in the vertical direction D, the container 520 is movable along the strip opening 510, and the sterile air leaves the sterile chamber SC through the strip opening 510. The mounting plate 300 and the guide plate 500 are respectively constructed as the top and bottom walls of the aseptic chamber SC, and filling is carried out within the aseptic chamber SC. The aseptic air guide pipe 610 continuously introduces aseptic air into the aseptic chamber SC to ensure the sterility of the aseptic chamber SC. The aseptic air leaves the aseptic chamber SC through the strip opening 510 to achieve the circulation of aseptic air. The container 520 is movable along the strip opening 510, which can be understood as the strip opening 510 defining the movement trajectory of the container 520. The container 520 moves along the strip opening 510 to reach directly below the discharge port 112, and the raw material in the valve chamber 110 enters the container 520 through the discharge port 112 to achieve filling. Furthermore, in addition to serving as the bottom wall of the aseptic chamber SC, the guide plate 500 also has a guiding function, guiding any condensate that may appear in the aseptic chamber SC to the strip opening 510, through which the condensate flows out.

[0093] For example, see continue. Figure 8AIn the filling apparatus according to an embodiment of the present disclosure, a plurality of filling valves are divided into at least one group, and the filling valves included in each group are arranged in two adjacent rows of filling valves. The sterile air guide tube 610 is located between the two rows of filling valves. At least a portion of the perforated plate 400 has a generally V-shaped cross section along the vertical direction D, and the lower vertex of the V-shape is located between the two rows of filling valves. The guide plate 500 includes two strip openings 510 corresponding to the two rows of filling valves respectively. At least a portion of the guide plate 500 has a generally W-shaped cross section along the vertical direction D, and the two lower vertices of the W correspond to the two strip openings 510 respectively. The upper vertex of the W-shape is located between the two rows of filling valves. The aseptic air guide pipe 610 is located between the two rows of filling valves. At least a portion of the perforated plate 400 has a generally V-shaped cross section along the vertical direction D, and the lower apex of the V-shape is also located between the two rows of filling valves. In this way, the V-shaped structure of the perforated plate 400 can reflect or refract the aseptic air flowing out from the multiple aseptic air guide ports on the side wall of the aseptic air guide pipe 610, causing the aseptic air to form a chaotic turbulent flow. As a result, the aseptic air diffuses more widely and is evenly distributed. Then, guided by the multiple through holes of the perforated plate 400, the widely distributed aseptic air flows downward evenly and forms a laminar flow to the vicinity of the discharge port 112 of each filling valve. This ensures the asepticity near the discharge port 112 of each filling valve and minimizes the disturbance of the laminar flow to the raw material flow from the discharge port 112 to the container. For example, the aseptic air guide 610 is located in the middle between the two rows of filling valves, and the lower apex of the V-shape is also located in the middle between the two rows of filling valves, which can better achieve the above effect. At least a portion of the guide plate 500 is generally W-shaped along the vertical direction D, with the two lower apexes of the W corresponding to the two strip openings 510 respectively, and the upper apex of the W-shape located between the two rows of filling valves. In this way, any condensate that may occur can be very effectively guided to the two strip openings 510. For example, the upper apex of the W-shape is located in the middle between the two rows of filling valves.

[0094] For example, according to an embodiment of this disclosure, the included angle at the lower vertex of the V-shape described above is 170°-175°. On the one hand, this included angle cannot be too large, as it will occupy space and be detrimental to the arrangement of other components. On the other hand, this included angle cannot be too small, otherwise it will not be able to reflect or refract the sterile air.

[0095] For example, according to the embodiments of this disclosure, the included angles at the lower and upper vertices of the W-shape described above are 170°-175° respectively. On the one hand, the included angles at these positions cannot be too large, as this would occupy space and be detrimental to the arrangement of other components. On the other hand, the included angles at these positions cannot be too small, otherwise they will not serve the purpose of guiding airflow.

[0096] For example, according to an embodiment of this disclosure, see Figure 8AAs described above, the second isolation element 140 is located in the sterile chamber SC. Together with the sterile chamber SC, the second isolation element 140 ensures the sterility of the second part 100-2 of the valve body 100, thereby ensuring the sterility at the outlet 112 and ensuring the realization of aseptic filling.

[0097] This disclosure also provides a filling system. Figure 9 This is a schematic diagram of the filling system according to an embodiment of the present disclosure; Figure 10A This is a schematic diagram of the structure of the injection valve in the filling system according to an embodiment of the present disclosure; and Figure 10B This is a second schematic diagram of the structure of the injection valve in the filling system according to an embodiment of this disclosure. See also... Figure 9 as well as Figure 10A and Figure 10BThe filling system according to an embodiment of this disclosure includes: a filling device 1000 as described above; and a preheating device 2000, a sterilizing device 3000, and a drying device 4000, wherein each of the preheating device 2000, the sterilizing device 3000, and the drying device 4000 includes a spray valve, the spray valve including: a spray valve body 700 having a valve cavity 710 and an outlet 711 communicating with the valve cavity 710, the valve cavity 710 extending in a vertical direction D, and the outlet 711 located at the lower end of the spray valve body 700 in the vertical direction D; and a spray valve stem 720 installed in the spray valve cavity 710. The device has a channel 721 that extends through the injection valve stem 720 in the vertical direction D, wherein the injection valve stem 720 is movable relative to the injection valve body 700 in the vertical direction D, and the injection valve body 700 is also movable in the vertical direction D. The injection valve further includes: a third isolator 730 disposed within the injection valve cavity 710, dividing the injection valve cavity 710 into a first part and a second part, with an outlet 711 located in the second part; or a fourth isolator 740 disposed outside the injection valve body 700, dividing the injection valve body 700 into a first part and a second part, with an outlet 711 located in the second part. For example, in a preheating device 2000, preheating gas (e.g., hot air) is injected via the channel 721 extending through the injection valve stem 720 into a container located at the preheating device 2000 to preheat a target portion of the container. For example, in sterilization equipment 3000, a sterilizing medium (e.g., hydrogen peroxide) is sprayed through channel 721 of the through-jet valve stem 720 onto a container located at sterilization equipment 3000 to sterilize the container. For example, in drying equipment 4000, a drying gas (e.g., nitrogen) is sprayed through channel 721 of the through-jet valve stem 720 onto a container located at drying equipment 4000 to dry the container, preparing it for filling. For example, the jet valve stem 720 can enter and exit valve chamber 710 through outlet 711, thereby adjusting the distance between the jet nozzle of the jet valve stem 720 (i.e., the opening of channel 721 near the container) and the container, so that in each of the preheating equipment 2000, sterilization equipment 3000, and drying equipment 4000, the corresponding jet valve stem 720 treats the container at an optimal distance. For example, the spray valve stem 720 is movable in the vertical direction D relative to the spray valve body 700, and the spray valve body 700 is also movable in the vertical direction D. Thus, in each of the preheating device 2000, the sterilization device 3000, and the drying device 4000, the spray valve has two independently controllable strokes, making the spray valve more flexible, adaptable to various application scenarios, and suitable for containers of different sizes to meet diverse user needs. For example, to ensure aseptic spraying in each of the preheating device 2000, the sterilization device 3000, and the drying device 4000, the spray valve in each of these devices also includes a third isolator 730 or a fourth isolator 740.For example, a third isolator 730 is disposed within the injection valve chamber 710, dividing the injection valve chamber 710 into a first part and a second part, with the outlet 711 located in the second part. This ensures the sterility of the second part of the injection valve chamber 710, thereby guaranteeing aseptic injection. Alternatively, a fourth isolator 740 is disposed outside the injection valve body 700, dividing the injection valve body 700 into a first part and a second part, with the outlet 711 located in the second part. This ensures the sterility of the area near the outlet 711, guaranteeing aseptic injection.

[0098] For example, see Figure 10A The third isolation element 730 is a sterilization gas barrier; the injection valve body 700 has an injection valve inlet 731 and an injection valve outlet 732 communicating with the injection valve cavity 710. Sterilization gas enters the injection valve cavity 710 from the injection valve inlet 731 and exits from the injection valve outlet 732 to form a sterilization gas barrier within the injection valve cavity 710; and in the vertical direction D, the downward stroke of the injection valve rod 720 is no greater than the size of the sterilization gas barrier. For example, in Figure 10A In the vertical direction D, the first part of the injection valve chamber 710 is located above the third isolation element 730, while the second part of the injection valve chamber 710 is located below the third isolation element 730. When the third isolation element 730 is a sterilization gas barrier, its working principle is the same as... Figure 1B The first isolation element 130 shown is basically similar and will not be described in detail here. Using a sterilizing gas barrier as the third isolation element 730 is easy to implement and low in cost. For example, the sterilizing gas can be any gas with sterilizing properties, such as high-temperature steam, vaporized hydrogen peroxide, etc.

[0099] For example, see Figure 10B The injection valve also includes a mounting plate 750; the fourth isolator 740 is a third retractable sleeve, fitted onto the injection valve body 700 and retractable in the vertical direction D; and the third retractable sleeve in the vertical direction D includes an upper end and a lower end, the upper end being fixed to the mounting plate 750, and the lower end being fixed to the lower end of the injection valve body 700. For example, the working principle of the fourth isolator 740 is similar to... Figure 1C The second isolator 140 shown is similar, and the first and second parts of the injection valve body 700 are also similar to the first part 100-1 and the second part 100-2 of the valve body 100, which will not be described again here.

[0100] For example, according to embodiments of this disclosure, the filling system includes a plurality of independent movable plates, respectively corresponding to the filling equipment 1000, the preheating equipment 2000, the sterilizing equipment 3000, and the drying equipment 4000. The movable plates in each of the filling equipment 1000, the preheating equipment 2000, the sterilizing equipment 3000, and the drying equipment 4000 can be referred to... Figure 8AThe movable plate 200 shown will not be described in detail here. Multiple movable plates are respectively set for the filling equipment 1000, the preheating equipment 2000, the sterilization equipment 3000 and the drying equipment 4000 and are independent of each other, which facilitates flexible adjustment of the valve body position according to the specific situation of each equipment.

Figure 8A The mounting plate 300 shown will not be described in detail here. Multiple mounting plates are respectively set for the filling equipment 1000, the preheating equipment 2000, the sterilization equipment 3000 and the drying equipment 4000, and are independent of each other, which facilitates flexible installation of valve bodies according to the specific situation of each equipment.

[0102] For example, according to an embodiment of this disclosure, the filling system includes a plurality of perforated plates that are independent of each other, respectively corresponding to the filling equipment 1000, the preheating equipment 2000, the sterilizing equipment 3000, and the drying equipment 4000. The perforated plates in each of the filling equipment 1000, the preheating equipment 2000, the sterilizing equipment 3000, and the drying equipment 4000 can be referred to... Figure 8A The perforated plate 400 shown will not be described in detail here. Multiple perforated plates are set up independently for filling equipment 1000, preheating equipment 2000, sterilization equipment 3000 and drying equipment 4000, respectively, which facilitates flexible diversion of sterile air according to the specific conditions of each equipment.

[0103] For example, according to an embodiment of this disclosure, the filling system includes a plurality of independent guide vanes, respectively corresponding to the filling equipment 1000, the preheating equipment 2000, the sterilizing equipment 3000, and the drying equipment 4000. The guide vanes in each of the filling equipment 1000, the preheating equipment 2000, the sterilizing equipment 3000, and the drying equipment 4000 can be referred to... Figure 8A The guide plate 500 shown will not be described in detail here. Multiple guide plates are set up independently for the filling equipment 1000, preheating equipment 2000, sterilization equipment 3000 and drying equipment 4000, respectively, so as to flexibly guide the condensate in each sterile chamber according to the specific situation of each equipment.

[0104] For example, according to an embodiment of this disclosure, in the vertical direction D, the movable plate, mounting plate, perforated plate, and guide plate in each of the filling equipment 1000, preheating equipment 2000, sterilization equipment 3000, and drying equipment 4000 are arranged sequentially from top to bottom. This arrangement can be referred to as... Figure 8AThis will not be elaborated upon here.

[0105] The above are merely exemplary embodiments of this disclosure and are not intended to limit the scope of protection of this disclosure, which is determined by the appended claims.
