Description

Technical Field

[0001] This utility model relates to the field of valve plate technology, and in particular to a lightweight, high-sealing, fast-ventilating valve. Background Technology

[0002] Currently, many packaging bags are typically equipped with vent valves during production to expel gas from the bag and prevent it from expanding or bursting. Traditional vent valves usually use a one-way venting method, where excess gas inside the bag is expelled through the vent valve, and outside air does not enter the packaging bag.

[0003] The one-way vent valve has one radially connected end to the valve body, and the other end has a gap between it and the valve body. When the gas inside the packaging bag reaches a certain pressure, the gas can push the vent valve open from the inside out and flow to the outside of the packaging bag along the gap. When the pressure inside the bag decreases to an insufficient level to open the valve, the valve closes. The valve only opens when the pressure inside the bag is higher than the pressure outside, thus preventing external air from entering the packaging bag and preventing the contents from being oxidized and contaminated. When the packaging bag is squeezed, the internal gas flows out along the vent valve, allowing the user to directly smell the contents and confirm their freshness.

[0004] Regarding the aforementioned technologies, when the pressure inside the packaging bag is too high, the gas inside the packaging bag pushes one side of the valve plate outward. The gas flows outward along the gap between one side of the valve plate and the vent valve body. This can easily lead to slow gas discharge, causing the pressure difference between the inside and outside of the packaging bag to gradually increase, which in turn can cause the packaging bag to burst. Therefore, there is an urgent need for a vent valve with high exhaust efficiency. Utility Model Content

[0005] To improve the exhaust efficiency of the vent valve, this application provides a lightweight, high-sealing, fast-release vent valve.

[0006] This application provides a lightweight, high-sealing-performance, fast-venting valve, employing the following technical solution: A lightweight, high-sealing, fast-venting valve includes a valve body comprising an inner ring, an outer ring, and a valve plate. The outer ring has a larger diameter than the inner ring. The inner ring is located inside the outer ring and communicates with it. A baffle plate is sealed on the side of the inner ring away from the outer ring, and an exhaust hole is opened on the baffle plate. The valve plate is located on the side of the baffle plate closer to the outer ring, and a gap is left between it and the inner wall of the inner ring along the circumference. A blocking member is fixed on the inner wall of the inner ring to prevent the valve plate from detaching from the inner ring. The blocking member is located on the side of the valve plate away from the baffle plate and does not exceed the end face of the outer ring away from the inner ring.

[0007] By adopting the above technical solution, the outer ring supports and fixes the vent valve body by bonding it to the packaging bag, and the inner ring supports the valve plate by means of a baffle. When the user squeezes the packaging bag, the valve plate moves back and forth along the axis of the inner ring, expanding the exhaust area and thus increasing the exhaust volume. The baffle limits the displacement of the valve plate along the axis, reducing the probability of the valve plate falling off the inner ring. The gas inside the packaging bag flows to the outside through the exhaust hole and along the gap between the valve plate and the inner wall of the inner ring, which helps to improve the exhaust efficiency of the device.

[0008] Optionally, the shielding component includes a plurality of baffles, which are arranged circumferentially along the inner wall of the inner ring. The ends of the baffles away from the inner ring are all moved toward the axis of the inner ring, and the baffles are inclined from the inner ring toward the outer ring.

[0009] By adopting the above technical solution, several baffles limit the axial displacement of the valve plate and provide deformable space for the valve plate in the vertical direction, which helps to reduce the probability of damage caused by contact between the valve plate and the baffle, and extends the service life of the valve plate.

[0010] Optionally, a coating is applied between the valve plate and the baffle plate.

[0011] By adopting the above technical solution, the coating covers the gap between the valve plate and the baffle, so that a vacuum is formed between the inner ring, the baffle and the valve plate, reducing the probability of external air entering the vent valve. At the same time, it continuously wets the valve plate, delays the aging of the valve plate, which helps to improve the sealing effect of the device and extend the service life of the valve plate, and reduces the probability of the contents of the packaging bag deteriorating.

[0012] Optionally, a filter screen is provided on the side of the baffle away from the valve plate, and the filter screen covers the exhaust hole.

[0013] By adopting the above technical solution, when the packaging bag is squeezed, the filter screen blocks the contents inside the packaging bag, reducing the probability of the contents being discharged through the vent.

[0014] Optionally, the exhaust holes are provided in a plurality of manner, and the plurality of exhaust holes are arranged circumferentially along the baffle.

[0015] By adopting the above technical solution, the diameter of some vent holes is relatively small, which helps to reduce the probability of the coating penetrating into the inside of the packaging bag along the vent holes and causing contamination to the contents.

[0016] Optionally, a guide block is provided below the baffle, and the valve plate is located between the guide blocks, with a gap between the outer circle of the valve plate and the guide block.

[0017] By adopting the above technical solution, several guide blocks cooperate to limit the lateral displacement of the valve plate, thereby making the coating evenly distributed between the valve plate and the baffle, which is beneficial to improving the sealing effect of the coating.

[0018] Optionally, a circular groove is provided circumferentially at one end of the valve plate near the baffle plate.

[0019] By adopting the above technical solution, the circular groove accommodates the coating, further improving the contact effect between the coating and the valve plate, thereby further improving the sealing effect of the device.

[0020] Optionally, the inner wall of the inner ring is provided with an annular groove along the circumferential direction on the side of the baffle near the inner ring. The inner wall of the annular groove near the outer ring is parallel to the end face of the outer ring. The inner wall of the annular groove near the inner ring is provided with an arc-shaped surface, and the arc-shaped surface is recessed from the outer ring towards the baffle.

[0021] By adopting the above technical solution, when the packaging bag changes direction, it drives the vent valve to change direction. At this time, the annular groove temporarily stores the coating, and the special protective coating can flow back between the valve plate and the baffle along the arc surface, reducing the probability of coating leakage.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The outer ring supports and fixes the vent valve body by bonding with the packaging bag, and the inner ring supports the valve plate by a baffle. When the user squeezes the packaging bag, the valve plate moves back and forth along the axis of the inner ring, expanding the exhaust area and thus increasing the exhaust volume. The baffle limits the displacement of the valve plate along the axis, reducing the probability of the valve plate falling off the inner ring. The gas in the packaging bag flows to the outside through the exhaust hole and along the gap between the valve plate and the inner wall of the inner ring, which helps to improve the exhaust efficiency of the device. 2. Several baffles limit the axial displacement of the valve plate and provide deformable space for the valve plate in the vertical direction, which helps to reduce the probability of damage caused by contact between the valve plate and the baffle, and extends the service life of the valve plate. 3. The coating covers the gap between the valve plate and the baffle, creating a vacuum between the inner ring, the baffle, and the valve plate. This reduces the probability of external air entering the vent valve and continuously wets the valve plate, delaying its aging. This improves the sealing effect of the device, extends the service life of the valve plate, and reduces the probability of the contents of the packaging bag deteriorating.

[0028] The present application will be further described in detail below with reference to all the accompanying drawings.

[0029] This application discloses a lightweight, high-sealing, fast-venting valve. Example

[0030] Reference Figure 1 and Figure 2 A lightweight, high-sealing, fast-release vent valve includes a vent valve body 1. The vent valve body 1 includes an inner ring 2, an outer ring 3, and a valve plate 4. The inner ring 2 is located inside and communicates with the outer ring 3. The valve plate 4 is located inside the inner ring 2, with a gap between it and the inner wall of the inner ring 2. A baffle 22 is sealed on the side of the inner ring 2 away from the outer ring 3. The baffle 22 is parallel to the valve plate 4 and located on the side of the valve plate 4 facing away from the outer ring 3. The inner ring 2 and the baffle 22 cooperate to support the valve plate 4. In the installed state, the end face of the outer ring 3 facing away from the inner ring 2 is bonded to the packaging bag, so that the outer ring 3 supports and fixes the vent valve body 1, which helps to improve the stability of the device during operation.

[0031] Reference Figure 2 and Figure 3 The baffle plate 22 has multiple vent holes 221 circumferentially arranged, and the inner wall of the inner ring 2 has a blocking component circumferentially arranged, including multiple baffles 24. The baffles 24 are located on the side of the valve plate 4 closer to the outer ring 3. The ends of all baffles 24 away from the inner ring 2 are closer to the axis of the inner ring 2, and the baffles 24 are inclined from the inner ring 2 to the outer ring 3 along the axis. When the packaging bag is squeezed, the valve plate 4 moves away from the baffle plate 22 along the axis of the inner ring 2, thereby increasing the distance between the valve plate 4 and the baffle plate 22, thus increasing the exhaust volume. The gas in the packaging bag passes through the vent holes 221 and flows to the outside along the gap between the valve plate 4 and the inner ring 2, which helps to improve the exhaust efficiency of the device.

[0032] Reference Figure 2 and Figure 4 When the valve plate 4 moves away from the baffle 22, the baffle 24 limits the displacement of the valve plate 4 along the axis of the inner ring 2, reducing the probability of the valve plate 4 falling out of the inner ring 2. The inclined side of the baffle 24 provides the valve plate 4 with variable space along the axis of the inner ring 2, reducing the probability of damage to the valve plate 4 when it comes into contact with the baffle 24, which helps to extend the service life of the valve plate 4. A filter screen 23 is provided on the side of the baffle 22 away from the valve plate 4. The filter screen 23 blocks the contents of the packaging bag, reducing the probability of the contents of the packaging bag being discharged through the vent 221.

[0033] Reference Figure 2 A coating is applied between the valve plate 4 and the baffle plate 22. The coating is mainly composed of silicone oil, specifically dimethyl silicone oil. The silicone oil creates a vacuum space between the baffle plate 22, the valve plate 4, and the inner ring 2, reducing the probability of external air and water vapor entering the packaging bag. The silicone oil continuously wets the valve plate 4, which helps to delay its aging and extend its service life.

[0034] Reference Figure 2 Guide blocks 25 are fixed at the lower end of the baffle 24. Several guide blocks 25 cooperate to limit the lateral displacement of the valve plate 4, so that the coating is evenly distributed between the valve plate 4 and the baffle 22, which is beneficial to improving the sealing effect of the coating.

[0035] Reference Figure 1 and Figure 2 A circular groove 41 is provided on the side of the valve plate 4 near the baffle 22 along the circumference. The coating is applied to the circular groove 41 and wraps the gap between the circular groove 41 and the valve plate 4, so that the coating is in full contact with the valve plate 4 and the baffle 22, thereby further improving the sealing effect of the device.

[0036] Reference Figure 1 and Figure 2 The inner ring 2 has an annular groove 21 circumferentially formed on its inner wall. The inner wall of the annular groove 21 near the outer ring 3 is parallel to the end face of the outer ring 3, and the inner wall near the valve plate 4 has an arc-shaped surface 211 that is concave towards the inner ring 2. When the packaging bag is tilted, it causes the vent valve to change its angle and direction, allowing the coating to flow along the inner wall of the inner ring 2 into the annular groove 21. The annular groove 21 temporarily stores the coating. When the packaging bag is reset, the coating flows back along the arc-shaped surface 211 into the gap between the valve plate 4 and the baffle 22, which helps to reduce the probability of coating overflow and waste.

[0037] The implementation principle of a lightweight, high-sealing, fast-venting valve according to an embodiment of this application is as follows: When the user tightens the packaging bag, the air inside the packaging bag is discharged through the exhaust hole 221, pushing the valve plate 4 closer to the outer ring 3 along the axis of the inner ring 2. The baffle 24 blocks the valve plate 4, reducing the probability of the valve plate 4 falling off from the inner ring 2. The gas inside the packaging bag flows to the outside through the gap between the valve plate 4 and the inner ring 2. The coating makes the inner ring 2, the baffle 22 and the valve plate 4 form a sealed space, reducing the probability of outside air and water vapor entering the packaging bag and contaminating the contents. During the exhaust process, the valve plate 4 and the baffle 22 are completely separated, expanding the exhaust area and thus increasing the exhaust volume, which helps to speed up the exhaust speed of the venting valve.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
