Description

Technical Field

[0001] This utility model relates to the field of storage container technology, specifically to a valve, liquid bag, and container. Background Technology

[0002] Medium bulk containers (IBCs), as standardized containers, are widely used in the storage and transportation of liquid materials in industries such as chemicals, food, pharmaceuticals, and coatings. Their discharge valves, as key components controlling material outflow, directly affect the efficiency of the entire packaging system due to their reliability, operational safety, and ease of maintenance. Currently, medium bulk containers typically transport liquids using liquid bags inside the container, with valves on these bags fixed to the container's discharge port using clamps.

[0003] Chinese patent publication number CN103759032B discloses a valve in which the fixing clip and valve body are combined into an integrated housing. This type of housing is prone to problems such as being difficult to disassemble and assemble, being easy to break, or losing the sealing performance of the housing during use.

[0004] Chinese Patent Publication No. CN103395582B discloses a discharge port fixing clip for a medium-sized bulk container. The clip includes a base and an elastic connecting buckle for connecting to the discharge port of the container. The base has an elastically deformable extension, one end of which forms a clamping opening for holding the discharge port, and the other end is connected to the base. When the clip is installed onto the discharge port of the container, the extension deforms elastically, increasing the clamping opening size. After installation, the extension deforms elastically again, decreasing the clamping opening size to hold the discharge port. This clip is suitable for assembly after valves or flanges are welded onto the liquid bag; otherwise, the clamp would prevent the valve from being welded to the liquid bag body.

[0005] In response, this utility model proposes a valve in which the fixing clamp structure does not affect the welding of the valve and the liquid bag. Summary of the Invention

[0038] like Figure 1 and Figure 2 As shown, this utility model provides a valve 100, which includes a valve body 11, an inner valve seat 12, a flange 13, a valve core 14, a valve stem 15, a valve cover 16, and a fixing clamp 17. The flange 13 is located at one end of the valve body 11 and is sealed to the valve body. A flange sealing ring 18 is clamped between the flange 13 and the valve body 11. The flange 13 is used for docking with a container. The valve body 11 has a channel 110 penetrating the valve body 11. The valve core 14 is movably disposed within the channel 110. The inner valve seat 12 is disposed within the channel 110 and is located on the side of the valve core 14 away from the flange 13, and is sealed to the valve body 11. The valve stem 15 penetrates the valve body 11 and is drivenly connected to the valve core located within the channel 110, so as to drive the valve core 14 to move and press against the inner valve seat 12 to close the channel 110 or drive the valve core 14 to separate from the inner valve seat 12 to open the channel 110. The valve cover 16 is located at the other end of the valve body 11 opposite to the flange 13 and is sealed to the valve body 11. An outer valve seat 19 is also provided between the valve cover 16 and the valve body 11. The valve cover 16 can be operably pressed into contact with the outer valve seat 19 to achieve a sealed connection between the valve cover 16 and the valve body. The valve cover 16 is used to cover the opening of the channel 110 away from the flange 13 when the container is not draining, so as to prevent debris from entering the channel 110 and affecting the opening and closing and sealing performance of the valve 100.

[0039] See Figures 3-6 The fixing clip 17 includes a fixing frame body 170. In this embodiment, the fixing clip body 170 is a flat structure with approximately rounded corners and rectangles, but it is not limited to this; other shapes of fixing clip bodies are also applicable. A fixing ring 171 matching the outer peripheral surface of the valve body 11 is provided in the middle of the fixing clip body 170. Two opposing lugs 172 are provided on the outer periphery of the fixing ring 171. The lugs 172 along the valve body are used to fix the valve to the discharge port of the medium-sized bulk container.

[0040] The fixing ring 171 protrudes along the axial direction of the valve body 11 to form a fixing ring mounting platform 173. The outer circumferential surface of the valve body 11 is provided with a valve body mounting platform 111 and a blocking protrusion 112 that protrude radially along the valve body. The valve body mounting platform 111 and the blocking protrusion 112 are spaced apart along the axial direction of the valve body to form a limiting groove 113 for accommodating the fixing ring mounting platform 173. The fixing ring mounting platform 173 can be inserted into the limiting groove and is restricted within the limiting groove by the valve body mounting platform 111 and the blocking protrusion 112, thereby fixing the fixing clip 17 to the outer circumference of the valve body 11, and realizing the fixed connection between the fixing clip 17 and the valve body 11.

[0041] The valve body mounting bracket 111 has a front end near the valve cover along the axial direction of the valve body, and a rear end opposite to it. The front end of the valve body mounting bracket 111 has a guide ramp 111a, and the rear end has a locking step 111b. The fixing clip 17 is inserted into the limiting groove 113 along the guide ramp 111a. The front end of the fixing ring mounting bracket 173 abuts against the locking step 111b to restrict its movement towards the front, and the rear end of the fixing ring mounting bracket 173 abuts against the blocking boss 112 to restrict its movement towards the rear. During assembly, the fixing clip 17 moves from the valve cover towards the flange to engage with the valve body, and force is applied in this direction to engage the fixing clip 17 into the limiting groove 113 along the guide ramp 111a.

[0042] See also Figures 3-6 The valve body 11 has locating ribs 114 extending axially on its outer peripheral surface, and a locating groove 174 matching the locating ribs 114 is provided on the inner wall of the fixing ring 171. During assembly, the locating grooves 174 correspond one-to-one with the corresponding locating ribs 114, and the fixing clip 17 is fixed to the valve body 11 along the extending direction of the locating ribs 114. Preferably, the locating groove 174 has a wedge-shaped structure with a narrow front and wide rear in the axial direction of the valve body to facilitate the positioning between the fixing clip 17 and the locating ribs 114 on the valve body.

[0043] See Figures 7-9 , Figures 7-9 A schematic diagram showing the process of fixing the retaining clip 17 to the valve body 11 is shown. Figure 7 A schematic diagram shows the fixing clip 17 sleeved on the valve body 11. Figure 8 This diagram illustrates the process by which the fixing clip 17 engages with the limiting groove 113 along the guide slope 111a. Figure 9 A schematic diagram is shown where the retaining clip 17 is inserted into the limiting groove 113.

[0044] See also Figures 1-6The outer peripheral surface of the valve body 11 is provided with a boss portion 115 that protrudes radially along the valve body 11. The middle part of the boss portion 115 has a mounting hole 1151 that passes through the boss portion 115 and communicates with the channel of the valve body 11. The valve stem 15 extends into the channel through the mounting hole 1151 and is driven to connect with the valve core 14. Correspondingly, the fixing clip 17 is provided with a clearance notch 175 at the position corresponding to the boss portion 115 to avoid the boss portion 115 during assembly.

[0045] See also Figure 3 , Figure 11 The valve stem 15 includes a rotating portion 151 that mates with the mounting hole 1151 and a handle portion 152 that is fixedly connected to the rotating portion 151. The rotating portion 151 has a generally cylindrical structure and includes a positioning post 1511, a transition post 1512, and a connecting post 1513 that are sequentially connected from the inside to the outside of the channel 110, wherein the rotating portion 151 is rotatably located within the mounting hole 111. The outer circumferential surface of the connecting post 1513 is provided with an annular groove for fixing the valve stem sealing ring, so that the connecting post 1513 is sealed to the valve body 11. The connecting post 1513 is provided with a valve stem mounting platform 15131, and the fixing clip 17 is provided with a blocking portion 176 that mates with the valve stem mounting platform 15131. The valve stem mounting platform 15131 and the blocking portion 176 cooperate to prevent the rotating portion 151 from disengaging from the mounting hole 111. Preferably, to facilitate the engagement and fixation between the valve stem mounting platform 15131 and the blocking part 171, a tapered valve stem mounting platform guide surface 15132 is provided on the front section of the valve stem mounting platform 15131 facing into the channel.

[0046] The valve fixing clip provided by this utility model can be sleeved onto the valve body from the valve cover direction and fixedly connected to the valve body. Therefore, when welding the valve onto the liquid bag, the flange can be welded and fixed to the liquid first, and then the entire valve structure can be assembled. Therefore, it will not affect the welding of the valve and the liquid.

[0047] The preferred embodiments of this utility model have been described in detail above. However, it should be understood that after reading the above teachings, those skilled in the art can make various alterations or modifications to this utility model. These equivalent forms also fall within the scope defined by the appended claims.
