According to an embodiment of the present disclosure, a filling valve is provided for filling a container with a raw material. The raw material is, for example, a food such as milk, beverage, vegetable puree, etc. Fig. 1A is a schematic structural view of a filling valve according to an embodiment of the present disclosure, fig. 2A is a schematic structural view of a second filling valve according to an embodiment of the present disclosure, fig. 3A is a schematic structural view of a third filling valve according to an embodiment of the present disclosure, and fig. 5A is a schematic structural view of a fourth filling valve according to an embodiment of the present disclosure. Referring to fig. 1A, 2A, 3A and 5A, a filling valve according to an embodiment of the present disclosure includes: the valve body 100 is provided with a valve cavity 110, a feed port 111 and a discharge port 112 which are communicated with the valve cavity 110, the valve cavity 110 extends along a vertical direction D, and the discharge port 112 is positioned at the lower end of the valve body 100 along the vertical direction D; and a valve stem 120 installed in the valve chamber 110; wherein the valve stem 120 is movable in a vertical direction D relative to the valve body 100, and the valve body 100 is movable in the vertical direction D; and the filling valve further comprises: a first separator 130 disposed in the valve chamber 110 to separate the valve chamber 110 into a first portion 110-1 and a second portion 110-2, and a feed port 111 and a discharge port 112 are disposed in the second portion 110-2; and a second separator 140 disposed outside the valve body 100 to separate the valve body 100 into a first portion 100-1 and a second portion 100-2, and the discharge port 112 is located at the second portion 100-2.

For example, the feedstock enters the valve chamber 110 through the inlet port 111 and exits the valve chamber 110 through the outlet port 112 to be filled into a container (e.g., the container 520 shown in fig. 8A). In fig. 1A, 2A, 3A, and 5A, the pipe connected to the feed port 111 is a pipe for conveying raw materials.

According to an embodiment of the present disclosure, the valve stem 120 is movable in a vertical direction D relative to the valve body 100. For example, the valve stem 120 moves downward in the vertical direction D relative to the valve body 100, the valve stem 120 closes the discharge port 112, and the material cannot leave the valve chamber 110 through the discharge port 112, and the filling stops. For example, the valve stem 120 is moved upward in the vertical direction D relative to the valve body 100, the valve stem 120 no longer closes the outlet port 112, and material exits the valve cavity 110 through the outlet port 112 into the container, and filling proceeds. Bacteria may be carried into the raw material that has entered the valve chamber 110 during the upward and downward movement of the valve stem 120 in the vertical direction D (for example, bacteria may be carried out of the valve chamber 110 by the upper end of the valve stem 120 as the valve stem 120 moves upward, and then enter the valve chamber 110 with the upper end of the valve stem 120 as the valve stem 120 moves downward), causing raw material contamination; to avoid this, a filling valve according to an embodiment of the present disclosure includes a first spacer 130 disposed within the valve chamber 110 to separate the valve chamber 110 into a first portion 110-1 and a second portion 110-2, with the feed port 111 and the discharge port 112 being located in the second portion 110-2. Since the feed port 111 and the discharge port 112 are located in the second portion 110-2, the material entering the valve chamber 110 will be located in the second portion 110-2 of the valve chamber 110, and the first portion 110-1 of the valve chamber 110 can be isolated from the material located in the second portion 110-2 of the valve chamber by providing the first separator 130, ensuring that bacteria in the first portion 110-1 of the valve chamber 110 will not reach the material in the second portion 110-2 of the valve chamber 110. The first spacer 130 ensures sterility of the second portion 110-2 of the valve chamber 110 so that even if the valve stem 120 moves up and down, it does not cause any contamination of the material entering the valve chamber 110. For example, in the vertical direction, the first portion 110-1 is at least partially above the second portion 110-2. For example, the first separator 130 isolates the feed port 111 and the discharge port 112 from the upper region of the valve chamber 110, thereby isolating all of the feedstock that has entered the valve chamber 100 from the upper region of the valve chamber 110. By providing the first separator 130, the upper region of the valve chamber 110 is isolated from the lower region of the valve chamber 110 including the feed port 111 and the discharge port 112, and sterility of the lower region of the valve chamber 110 including the feed port 111 and the discharge port 112 is ensured, so that any contamination of the raw material entering the valve chamber 110 is not caused even if the valve stem 120 moves up and down.

It should be noted that in the disclosed embodiment, the first spacer 130 "separates" the valve chamber 110 into the first portion 110-1 and the second portion 110-2 to the extent that bacteria that reach the first portion 110-1 cannot enter the second portion 110-2. Thus, bacteria of the first portion 110-1 do not contaminate the material in the second portion 110-2, ensuring that aseptic filling is achieved.

According to an embodiment of the present disclosure, the valve body 100 is movable in a vertical direction D; in this way, the distance between the discharge port 112 of the filling valve and the container can be adjusted to be the most suitable distance for raw materials to enter the container according to the actual filling condition, and flexibility and controllability of the filling valve according to the embodiment of the disclosure are improved. Bacteria can be carried to the discharge port 112 during the vertical up and down movement of the valve body 100, which causes raw material pollution; to avoid this, a filling valve according to an embodiment of the present disclosure includes a second separator 140 disposed outside the valve body 100 to separate the valve body 100 into a first portion 100-1 and a second portion 100-2, with the spout 112 located in the second portion 100-2. Since the discharge port 112 is located in the second portion 100-2, the first portion 100-1 of the valve body 100 can be isolated from the discharge port 112 by providing the second separator 140, ensuring that bacteria in the first portion 100-1 of the valve body 100 do not reach the discharge port 112. The second separator 140 ensures sterility at the location of the discharge port 112 so that even if the valve body 100 moves up and down, it does not cause any contamination of the raw material to be filled into the container. For example, in the vertical direction, the first portion 100-1 is at least partially above the second portion 100-2. For example, the second separator 140 isolates the region of the valve body 100 other than the discharge port 112 from the external environment. The "external environment" herein refers to the aseptic chamber described below with reference to fig. 8A. By providing the second separator 140, the discharge port 112 is exposed to the aseptic chamber, and the area of the valve body 100 other than the discharge port 112 is isolated from the aseptic chamber, sterility at the position of the discharge port 112 is ensured, so that any contamination of the raw material to be filled into the container is not caused even if the valve body 100 moves up and down.

It should be noted that in the disclosed embodiment, the second separator 140 "separates" the valve body 100 into the first portion 100-1 and the second portion 100-2 to the extent that bacteria reaching the first portion 100-1 cannot enter the second portion 100-2. Thus, bacteria of the first portion 100-1 do not contaminate the material at the location of the discharge port 112, ensuring that aseptic filling is achieved.

According to the embodiment of the disclosure, the valve rod 120 is movable along the vertical direction D relative to the valve body 100, and the valve body 100 is movable along the vertical direction D, that is, the filling valve according to the embodiment of the disclosure has two independently controllable strokes, so that the filling valve according to the embodiment of the disclosure is more flexible, has various application scenes, can be used for filling different types of raw materials into containers with different specifications, and meets the diversity demands of users. Further, the filling valve according to embodiments of the present disclosure further comprises the first and second spacers 130, 140, in view of the risk that both separate strokes may introduce bacteria to contaminate the raw material, ensuring that the filling valve according to embodiments of the present disclosure may still achieve sterile filling with double strokes.

The specific structure of the first separator 130 and the second separator 140 is not limited in the embodiments of the present disclosure, as long as they can meet the above-described insulation requirements.

Fig. 1B is a simplified schematic illustration of portion A1 of the filling valve of fig. 1A. It should be noted that, for the simplified schematic diagrams of fig. 1B, and the subsequent fig. 1C, fig. 2B, fig. 3B, and fig. 5B, each relevant component is depicted in a very simplified manner for the sake of understanding, and the specific structure of each relevant component is omitted. Referring to fig. 1A and 1B, for example, the first barrier 130 is a sterilization gas barrier; the valve body 100 has an inlet port 131 and an outlet port 132 in communication with the valve cavity 110, the sterilizing gas entering the valve cavity 110 from the inlet port 131 and exiting the valve cavity 110 from the outlet port 132 to form a sterilizing gas barrier within the valve cavity 110; in the vertical direction D, both the air inlet 131 and the air outlet 132 are higher than the feed inlet 111; and in the vertical direction D, the valve stem 120 is moved downward a travel no greater than the size of the sterilizing gas barrier. In this way, the second portion 110-2 of the valve cavity 110 is maintained as a sterile field, and bacteria of the first portion 110-1 of the valve cavity 110 are not carried into the second portion 110-2 of the valve cavity 110 even if the valve stem 120 moves up and down, ensuring sterility of the second portion 110-2 of the valve cavity 110 and the raw materials contained therein. In addition, the use of a sterilization gas barrier as the first separator 130 is low in cost and less damaging to the raw materials. For example, the sterilizing gas may be any gas having sterilizing properties, and the embodiments of the present disclosure are not limited to a particular type of sterilizing gas. For example, the sterilizing gas may be high temperature steam, vaporized hydrogen peroxide, or the like.

Further, according to embodiments of the present disclosure, the sterilizing gas is a high temperature vapor; and in the vertical direction D, the air inlet 131 is higher than the air outlet 132. High-temperature steam is easy to obtain, environment-friendly and low in cost. For example, the temperature of the high temperature vapor is 130 degrees celsius or higher. In the case that the sterilizing gas is high-temperature vapor, the air inlet 131 is arranged higher than the air outlet 132 in the vertical direction D, so that the air outlet 132 can be used as a condensed water outlet, and condensed water (for example, condensed water formed by the fact that the high-temperature vapor hits the wall of the valve cavity 110) generated in the circulation process of the high-temperature vapor can be conveniently discharged out of the valve cavity 110, so that the condensed water is prevented from falling into the raw materials in the valve cavity 110.

Fig. 2B is a simplified schematic diagram of portion A3 of the filling valve of fig. 2A. Referring to fig. 2A and 2B, for example, the first spacer 130 is a first telescopic sleeve, sleeved on the valve rod 120 and telescopic in the vertical direction D; the first telescopic sleeve comprises an upper end 130U and a lower end 130L in the vertical direction D, the upper end 130U being fixed to the wall of the valve chamber 110, the lower end 130L being fixed to the valve stem 120; in the vertical direction D, the upper end 130U is higher than the feed port 111. Referring to fig. 2B, as the valve stem 120 moves upward in the vertical direction D, the first telescopic sleeve contracts; as the valve stem 120 moves downward in the vertical direction D, the first telescoping sleeve expands; thus, the first portion 110-1 and the second portion 110-2 of the valve chamber 110 are always isolated from each other by the first separator 130, ensuring sterility of the second portion 110-2 of the valve chamber 110. For example, the lower end 130L is also higher than the feed port 111 in the vertical direction D, which can prevent the first telescopic sleeve from pinching a portion of the raw material (e.g., particles in the raw material) during the telescoping process.

Fig. 3B is a simplified schematic diagram of portion A4 of the filling valve of fig. 3A. Referring to fig. 3A and 3B, for example, the first barrier 130 includes a first sterilization gas barrier 130a and a second sterilization gas barrier 130B; the valve body 100 has a first inlet port 131a and a first outlet port 132a in communication with the valve cavity 110, the first sterilizing gas entering the valve cavity 110 from the first inlet port 131a and exiting the valve cavity 110 from the first outlet port 132a to form a first sterilizing gas barrier 130a within the valve cavity 110; the valve body 100 has a second inlet port 131b and a second outlet port 132b in communication with the valve cavity 110, the second sterilizing gas entering the valve cavity 110 from the second inlet port 131b and exiting the valve cavity 110 from the second outlet port 132b to form a second sterilizing gas barrier 130b within the valve cavity 110; in the vertical direction D, the first air inlet 131a, the first air outlet 132a, the second air inlet 131b, and the second air outlet 132b are all higher than the feed inlet 111; and in the vertical direction D, the valve stem 120 is moved downward by a stroke not greater than the sum of the size of the first sterilizing gas barrier 130a and the size of the second sterilizing gas barrier 130 b. In this way, the second portion 110-2 of the valve chamber 110 remains a sterile area, and even if the valve stem 120 moves up and down, bacteria in the area of the valve chamber 110 above the first separator 130 (i.e., the first portion 110-1) are not carried into the area of the valve chamber 110 below the first separator 130 (i.e., the second portion 110-2), assuring sterility of the material within the valve chamber 110. For example, the first sterilizing gas is different from the second sterilizing gas, and the combination of the two can stably and effectively destroy various bacteria, thereby improving the sterilizing performance of the first sterilizing gas barrier 130a and the second sterilizing gas barrier 130b as a whole. For example, in the vertical direction D1, the first sterilizing gas of the upper first sterilizing gas barrier 130a is vaporized hydrogen peroxide, and the second sterilizing gas of the lower second sterilizing gas barrier 130b is high-temperature vapor.

Compared to the case where the first spacer 130 is the first telescopic sleeve in fig. 2B, the following advantageous effects can be obtained by using a sterilization gas barrier as the first spacer 130 in fig. 1B and 3B: (1) In the case that the raw material to be filled into the container contains particles, the first telescopic sleeve is easy to entrain the particles during the telescopic process, so that the subsequent telescopic movement stroke is influenced, and the telescopic movement of the first telescopic sleeve may cause the particles to be broken so as to influence the quality and uniformity of the raw material to be filled into the container, the above problems do not exist when the sterilizing gas barrier is used as the first separator 130; (2) The adoption of the sterilizing gas barrier as the first separator 130 saves more space, facilitates the arrangement of other components, and is beneficial to the compactness of the whole structure of the filling valve; (3) The use of a sterile gas barrier as the first spacer 130 is easier to achieve, while the use of a first telescoping sleeve as the first spacer 130 may increase assembly complexity.

Referring to fig. 1A and 1C, for example, the filling valve according to the embodiment of the present disclosure further includes a mounting plate 300, wherein the second spacer 140 is a second telescopic sleeve, sleeved on the valve body 100, and telescopic in the vertical direction D; and the second telescopic sleeve includes an upper end 140U and a lower end 140L in the vertical direction D, the upper end 140U being fixed to the mounting plate 300, the lower end 140L being fixed to the lower end of the valve body 100. Referring to fig. 1C, as the valve body 100 moves upward in the vertical direction D, the second telescopic sleeve contracts; as the valve body 100 moves downward in the vertical direction D, the second telescopic sleeve stretches; thus, the first portion 100-1 and the second portion 100-2 of the valve body 100 are always isolated from each other by the second separator 140, assuring sterility at the location of the discharge port 112. As described below, the mounting plate 300 and baffle 500 are configured as top and bottom walls, respectively, of the aseptic chamber SC, in which case the second barrier 140 is located within the aseptic chamber SC, ensuring sterility at the location of the discharge port 112, without the second barrier 140 taking up too much space.

In the case where the double-case link 160 is provided, the double-case link 160 is fixed to the mounting plate 300, and then the upper end 140U of the second telescopic tube is re-connected to the double-case link 160, compared with the case where the upper end 140U of the second telescopic tube is directly fixed to the mounting plate 300, the difficulty of assembly of the second telescopic tube can be reduced, thereby fixing the second telescopic tube more stably, so that the realization of the second spacer 140 is simpler and more stable.

In this way, the second portion 100-2 of the valve body 100 is maintained as a sterile field, and bacteria located in the first portion 100-1 of the valve body 100 are not carried into the second portion 100-2 of the valve body 100 even if the valve body 100 moves up and down, ensuring sterility at the location of the discharge port 112. In addition, the use of a sterilization gas barrier as the second separator 140 saves space, is easy to implement and is low in cost.

During filling of the raw material into the container, there may be a case where the container is insufficiently opened (for example, in the case of the container 520 shown in fig. 8A, which is a sheet-shaped plastic container, opposite inner surfaces of the container are easily adsorbed together), resulting in that the filling may not be smoothly performed. In order to prevent the case of insufficient opening of the container, the filling valve according to the embodiment of the present disclosure is provided with an air flow passage 123 penetrating the valve stem 120, and air is blown into the container through the air flow passage 123 before or during filling, so that the container is sufficiently opened, ensuring that filling is smoothly performed. For example, the gas blown into the container via the gas flow channel 123 is a food-grade safety gas, such as nitrogen.

Referring to fig. 7, the filling valve according to the embodiment of the present disclosure further includes a gas delivery pipe 170 and a connector 180; the connection member 180 has a first end 180U and a second end 180L opposite to each other, and has a passage 180C penetrating the connection member 180 from the first end 180U to the second end 180L, a cross section of the first end 180U perpendicular to the vertical direction D being smaller than a cross section of the second end 180L perpendicular to the vertical direction D; the gas line 170 is hermetically connected to the first end 180U of the connection member 180; the passage 180C of the connector 180 is aligned with the air flow passage 123 and the second end 180L of the connector 180 is air tightly connected to the valve stem 120. By providing the connection 180 shown in fig. 7, it is possible to very conveniently air-tightly communicate the gas line 170 with the gas flow passage 123 to deliver gas to the flow passage 123. 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, providing convenience for attaching the gas line 170 to the valve stem 120 or removing the gas line 170 from the valve stem 120 as desired. The second end 180L of the connector 180 is attached to the valve stem 120, for example, by rivets; for example, a sealing ring is provided at the connection location of the second end 180L of the connector 180 with the valve stem 120 to ensure that the two are hermetically connected.

For example, in a filling valve according to an embodiment of the present disclosure, the valve body 100 and the valve stem 120 are both made of a metallic material. For example, the metal material is stainless steel. The mechanical components such as the valve body 100 and the valve rod 120 are made of metal materials, so that the machining process is mature, the machining difficulty is low, and the cost is low.

For example, in a 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. In this case, the first conical surface 120S can more closely fit the second conical surface 112S, so as to improve the sealing performance of the valve rod 120 to the discharge port 112.

According to an embodiment of the present disclosure, there is also provided a filling apparatus. Fig. 8A is a schematic structural view of a filling apparatus according to an embodiment of the present disclosure. Referring to fig. 8A, a filling apparatus 1000 according to an embodiment of the present 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 to be movable in the vertical direction D as a whole. In fig. 8A, a valve body 100 of a filling valve is indicated and two rows of filling valves are shown as an example. By arranging the movable plate 200 which is movable along the vertical direction D, the movable plate 200 can move to drive the whole filling valves along the vertical direction D, so that the moving consistency of the filling valves is ensured, and the mass filling is facilitated; in addition, the movement of the movable plate 200 can drive the filling valves, so that the structure is simpler and more concise, and the space is saved compared with the situation that a separate driving mechanism is arranged for each filling valve.

For example, with continued reference to fig. 8A, the filling apparatus 1000 according to the embodiments of the present disclosure further includes a mounting plate 300, a porous plate 400, and a sterile wind guide 610, wherein the mounting plate 300 is disposed below the movable plate 200, the porous plate 400 is disposed below the mounting plate 300, and the sterile wind guide 610 is disposed between the mounting plate 300 and the porous plate 400 in the vertical direction D; each of the plurality of filling valves passes through the mounting plate 300; each of the plurality of filling valves passes through the porous plate 400, and the porous plate 400 has a plurality of through holes penetrating the porous plate 400 in the vertical direction D; the sterile wind guide pipe 610 extends in the vertical direction D and has a plurality of sterile wind guide ports formed in a sidewall thereof. As described above, the upper end 140U of the second telescoping tube is connected to the mounting plate 300. As described above, the air chamber housing 150 is connected to the mounting plate 300. The porous plate 400 has a plurality of through holes penetrating the porous plate 400 in the vertical direction D, and small black dots at the porous plate 600 in fig. 8A represent the through holes. A plurality of sterile wind guide ports are formed on the side wall of the sterile wind guide pipe 610, and small black dots at the side wall of the sterile wind guide pipe 610 in fig. 8A represent the sterile wind guide ports. Sterile air is delivered from the sterile air guide pipe 610 into a sterile chamber as described below and is spread out, and then is dispersed under the guide effect of a plurality of through holes of a porous plate and reaches the discharge ports 112 of a plurality of filling valves, so that the sterility of the sterile chamber and the sterility at the positions of the discharge ports 112 are maintained, and the realization of sterile filling is ensured.

Fig. 8B is a simplified schematic diagram of a bottom wall of a sterile wind delivery tube in a filling apparatus according to an embodiment of the present disclosure. For example, referring to fig. 8B, a bottom wall 610L of the sterile wind guide pipe 610 near the perforated plate 400 is a substantially closed structure in which only one opening 610H is provided. For example, the opening 610H serves to guide condensed water that may be formed. To ensure that the sterile wind spreads to a wider range, a plurality of sterile wind diversion openings are opened at the side wall of the sterile wind diversion pipe 610 as described above; if a plurality of sterile wind guide openings are also opened on the bottom wall 610L of the sterile wind guide pipe 610 near the porous plate 400, the range of the sterile wind flowing out from the bottom wall 610L is very limited, so in order to concentrate the sterile wind to flow out from the plurality of sterile wind guide openings of the side wall of the sterile wind guide pipe 610 to a wide range, the bottom wall 610L of the sterile wind guide pipe 610 is not provided with a sterile wind guide opening in the embodiment of the present disclosure, and the bottom wall 610L is provided with only one opening 610H for guiding condensed water which may be formed, so that the bottom wall 610L of the sterile wind guide pipe 610 is substantially closed. For example, in order to better guide condensed water that may be formed, an opening 610H is provided at a central position of the bottom wall 610L.

Further, with continued reference to fig. 8A, the filling apparatus according to an embodiment of the present disclosure further includes a sterile air duct 620, the sterile air duct 620 being hermetically connected with an end of the sterile air duct 610 near the mounting plate 300; the diameter of the sterile wind guide pipe 610 is larger than the diameter of the sterile wind delivery pipe 620. The sterile wind guide pipe 610 is located in a sterile chamber as described below, and is provided to have a larger diameter, which greatly facilitates the diffusion of sterile wind to various positions of the sterile chamber, ensuring sterility of the sterile chamber.

Further, with continued reference to fig. 8A, the filling apparatus according to the embodiments of the present disclosure further includes a baffle 500, wherein the baffle 500 is disposed below the porous plate 400 in the vertical direction D, and the mounting plate 300 and the baffle 500 are respectively configured as top and bottom walls of the aseptic chamber SC, and the aseptic wind guide pipe 610 continuously guides the aseptic wind into the aseptic chamber SC; the baffle 500 has a strip-shaped opening 510, the strip-shaped opening 510 being located directly below the discharge opening 112 of the filling valve in the vertical direction D, the container 520 being movable along the strip-shaped opening 510 and sterile wind exiting the sterile chamber SC through the strip-shaped opening 510. Mounting plate 300 and baffle 500 are configured as top and bottom walls, respectively, of aseptic chamber SC, and filling takes place within aseptic chamber SC; the sterile air guide pipe 610 continuously guides the sterile air into the sterile chamber SC to ensure sterility of the sterile chamber SC; sterile wind exits the sterile chamber SC through the strip opening 510 to enable circulation of the sterile wind. The container 520 is movable along the bar-shaped opening 510, which is understood that the bar-shaped opening 510 defines a moving track of the container 520; the container 520 moves along the strip-shaped opening 510 to a position right below the discharge port 112, and raw materials in the valve cavity 110 enter the container 520 through the discharge port 112, so that filling is realized. Further, the deflector 500 has a deflector function for guiding condensed water which may occur in the aseptic chamber SC to the strip-shaped opening 510 in addition to the bottom wall of the aseptic chamber SC, and the condensed water flows out through the strip-shaped opening 510.

For example, with continued reference to fig. 8A, in a filling apparatus according to an embodiment of the present disclosure, a plurality of filling valves are grouped into at least one group, each group including filling valves arranged in two immediately adjacent columns of filling valves, with a sterile wind draft tube 610 located between the two columns of filling valves; at least a portion of the perforated plate 400 is generally V-shaped in cross-section in the vertical direction D, with the lower apex of the V-shape being located between two rows of filling valves; the baffle 500 includes two strip-shaped openings 510 corresponding to the two rows of filling valves, respectively, at least a portion of the baffle 500 is generally W-shaped in the vertical direction D, two lower apexes of the W corresponding to the two strip-shaped openings 510, respectively, and an upper apex of the W is located between the two rows of filling valves. The sterile air guide pipe 610 is located between two rows of filling valves, at least part of the perforated plate 400 has a cross section in the vertical direction D which is substantially V-shaped, and the lower vertex of the V-shape is also located between two rows of filling valves, so that the V-shaped structure of the perforated plate 400 can reflect or refract the sterile air flowing out from the plurality of sterile air guide openings of the side wall of the sterile air guide pipe 610, so that the sterile air forms chaotic turbulence, and is more widely and uniformly distributed, and then the widely distributed sterile air is uniformly and downwardly directed under the guidance of the plurality of through holes of the perforated plate 400 to form laminar air to reach the vicinity of the discharge opening 112 of each filling valve, thereby ensuring the sterility in the vicinity of the discharge opening 112 of each filling valve and minimizing the disturbance of the laminar air to the raw material flow flowing from the discharge opening 112 to the container. For example, the sterile wind guide tube 610 is located at an intermediate position between two rows of filling valves, and the lower vertex of the V-shape is also located at an intermediate position between two rows of filling valves, so that the above effect can be better achieved. At least part of the deflector 500 has a substantially W shape in the vertical direction D, two lower apexes of the W correspond to the two strip-shaped openings 510, respectively, and an upper apex of the W shape is located between the two rows of filling valves, so that condensate water which may occur can be guided to the two strip-shaped openings 510 very effectively. For example, the upper apex of the W is located at an intermediate position between the two rows of filling valves.

For example, according to embodiments of the present disclosure, the included angle at the lower vertex of the V-shape as described above is 170 ° -175 °; on one hand, the included angle cannot be too large, so that space is occupied, and arrangement of other parts is not facilitated; on the other hand, the angle cannot be too small, otherwise it will not act to reflect or refract the sterile wind.

For example, according to embodiments of the present disclosure, the included angles at the lower and upper vertices of the W-shape as described above are 170 ° -175 °, respectively; on one hand, the included angles at the positions cannot be too large, so that the space is occupied, and the arrangement of other components is not facilitated; on the other hand, the included angles at the positions cannot be too small, otherwise the flow guiding effect cannot be achieved.

For example, in accordance with an embodiment of the present disclosure, referring to fig. 8A, the second separator 140 is located in the aseptic chamber SC as described above, and the second separator 140, together with the aseptic chamber SC, ensures sterility of the second portion 100-2 of the valve body 100, thereby ensuring sterility at the location of the discharge port 112, ensuring implementation of aseptic filling.

The embodiment of the disclosure also provides a filling system. FIG. 9 is a schematic structural view of a filling system according to an embodiment of the present disclosure; FIG. 10A is a schematic illustration of the configuration of an injection valve in a filling system according to an embodiment of the present disclosure; and fig. 10B is a schematic diagram of a second configuration of an injection valve in a filling system according to an embodiment of the present disclosure. Referring to fig. 9 and 10A and 10B, a filling system according to an embodiment of the present disclosure includes: filling plant 1000 as described above; and a preheating device 2000, a sterilizing device 3000, a drying device 4000, wherein each of the preheating device 2000, the sterilizing device 3000, and the drying device 4000 includes an injection valve including: an injection valve body 700 having an injection valve cavity 710 and an outlet 711 communicating with the injection valve cavity 710, the injection valve cavity 710 extending in a vertical direction D, the outlet 711 being located at a lower end of the injection valve body 700 in the vertical direction D; and an injection valve stem 720 installed in the injection valve cavity 710 and having a passage 721 penetrating the injection valve stem 720 in a vertical direction D, wherein the injection valve stem 720 is movable in the vertical direction D with respect to the injection valve body 700, and the injection valve body 700 is movable in the vertical direction D; and the injection valve further includes: a third spacer 730 disposed within the injection valve cavity 710, separating the injection valve cavity 710 into a first portion and a second portion, the outlet 711 being located in the second portion; alternatively, a fourth spacer 740 is disposed outside the injection valve body 700 to separate the injection valve body 700 into a first portion and a second portion, where the outlet 711 is located. For example, with the preheating device 2000, a preheating gas (e.g., hot air) is injected into a container located at the preheating device 2000 via a passage 721 through the injection valve stem 720 to preheat a target portion of the container. For example, with respect to the disinfection apparatus 3000, a disinfection medium (e.g., hydrogen peroxide) is sprayed via a channel 721 through the spray valve stem 720 to a container located at the disinfection apparatus 3000 to disinfect the container. For example, with the drying apparatus 4000, a drying gas (e.g., nitrogen) is injected via a passageway 721 through the injection valve stem 720 to a container located at the drying apparatus 4000 to dry the container in preparation for filling. For example, the spray valve stem 720 may be moved into and out of the valve cavity 710 via the outlet 711, thereby adjusting the distance between the spray orifice of the spray valve stem 720 (i.e., the opening of the passageway 721 near the container) and the container such that the respective spray valve stem 720 processes the container at an optimal distance in each of the pre-heating apparatus 2000, the sterilizing apparatus 3000, and the drying apparatus 4000. For example, the injection valve stem 720 is movable in the vertical direction D relative to the injection valve body 700 and the injection valve body 700 is movable in the vertical direction D, so that in each of the preheating device 2000, the sterilizing device 3000 and the drying device 4000, the injection valve has two independently controllable strokes, so that the injection valve is more flexible, has various application scenes, can be adapted to containers of different specifications, and meets various demands of users. For example, in order to ensure that the aseptic spraying is achieved in each of the preheating device 2000, the sterilizing device 3000, and the drying device 4000, the spraying valve in each of the preheating device 2000, the sterilizing device 3000, and the drying device 4000 further includes a third partition 730 or a fourth partition 740. For example, the third spacer 730 is disposed in the injection valve cavity 710 to separate the injection valve cavity 710 into a first portion and a second portion, and the outlet 711 is disposed in the second portion, so that sterility of the second portion of the injection valve cavity 710 can be ensured, thereby ensuring implementation of aseptic injection. For example, the fourth separator 740 is disposed outside the injection valve body 700 to separate the injection valve body 700 into a first portion and a second portion, and the outlet 711 is disposed in the second portion, so that sterility near the outlet 711 can be ensured, and sterile injection can be ensured.

For example, referring to fig. 10A, third spacer 730 is a sterilization gas barrier; the injection valve body 700 has an injection valve inlet 731 and an injection valve outlet 732 in communication with the injection valve cavity 710, the sterilizing gas entering the injection valve cavity 710 from the injection valve inlet 731 and exiting the injection valve cavity 710 from the injection valve outlet 732 to form a sterilizing gas barrier within the injection valve cavity 710; and in the vertical direction D, the downward travel of the spray valve stem 720 is no greater than the size of the sterilization gas barrier. For example, in fig. 10A, in the vertical direction D, a first portion of the injection valve cavity 710 is located above the third spacer 730, and a second portion of the injection valve cavity 710 is located below the third spacer 730. In the case where the third separator 730 is a sterilization gas barrier, the operation principle is substantially similar to that of the first separator 130 shown in fig. 1B, and will not be described herein. The use of a sterilization gas barrier as the third spacer 730 is easy to implement and low cost. For example, the sterilizing gas is any gas having sterilizing properties, such as high temperature steam, vaporized hydrogen peroxide, and the like.

For example, referring to fig. 10B, the injection valve further includes a mounting plate 750; the fourth spacer 740 is a third telescopic sleeve, and is sleeved on the injection valve body 700 and is telescopic in the vertical direction D; and the third telescopic sleeve includes an upper end fixed to the mounting plate 750 and a lower end fixed to the lower end of the injection valve body 700 in the vertical direction D. For example, the fourth separator 740 operates in a similar manner to the second separator 140 shown in fig. 1C, and the first and second parts of the injection valve body 700 are also similar to the first and second parts 100-1 and 100-2 of the valve body 100, which are not described in detail herein.
