A plurality of external clamping blocks 210 are arranged at intervals in the circumferential direction on the outer wall of the valve body 200. The plurality of external clamping blocks 210 are used for clamping with the alpha valve. Optionally, the connecting sleeve 260 can be sleeved on the outer side of the opening 130 of the docking bag, can be sleeved on the inner side of the opening 130, or can be connected to the upper end of the opening 130.

[0030] The utility model provides a sealed quick docking bag containing a Beta valve. Compared with the prior art, the Beta valve includes a valve body 200 and a valve cover 300. The connecting sleeve 260 is mounted on the opening 130 of the docking bag and fixed by welding. When materials need to be transferred, the valve cover 300 is movably mounted inside the valve body 200, and a sealing ring is used to close the gap between the valve body 200 and the valve cover 300 to ensure the sealing effect between the two. When it is necessary to dock with the α valve, the valve cover 300 is removed, and the multiple external clamping blocks 210 on the outer wall of the valve body 200 are clamped with the clamp of the α valve to achieve quick docking of the transfer bag and the α valve. The utility model provides a sealed quick docking bag containing a Beta valve, which can achieve quick docking with the α valve, ensure that materials will not leak, and prevent materials from causing harm to the human body during the transfer process.

[0031] The Beta valve is made of plastic, and the sealing ring is made of silicone material that meets FDA requirements, which is wear-resistant and resistant to wet heat sterilization (121°C, 30 minutes). The connecting sleeve 260 of the Beta valve can be fixed to the opening 130 of the docking bag by welding, or an annular interface connected to the opening 130 can be provided on the docking bag, and the connecting sleeve 260 is welded and fixed to the annular interface, or the annular interface and the connecting sleeve 260 are fixed together by an external clamp. A sealing ring can be optionally provided on the inner side of the clamp, and the sealing ring and the clamp ensure the sealing of the connection, and the clamp clamps the bag body and the valve body together.

[0032] Specifically, the bag body 100 includes a first sheet layer 110 and a second sheet layer 120, the edges of the first sheet layer 110 and the second sheet layer 120 are heat-sealed to form a transfer chamber inside the bag body 100, and an opening 130 is opened on the bag body 100 to connect the transfer chamber.

[0033] See also Fig. 9 In the first embodiment, the first sheet 110 is a light-transmitting layer, and the second sheet 120 is a light-blocking and breathable layer. Specifically, the first sheet 110 is a barrier layer with a thickness of 80 μm-90 μm, which is made by a blow molding process, and a high-density polyethylene film that can block bacteria but is breathable is made by flash evaporation of high-density polyethylene particles. The air permeability is tested by the Gurley method: the time for 100 cc of gas to pass through is 14-20 seconds.

[0034] In the second embodiment, the first sheet 110 and the second sheet 120 are both light-transmitting layers. Specifically, the first sheet 110 and the second sheet 120 are both made of low-density polyethylene particles, and a 80-200 μm thick film is obtained by a film blowing process. The first sheet 110 and the second sheet 120 are cut and heat-sealed to obtain a bag body 100 of a desired shape and appropriate specifications.

[0035] The bag body 100 in the above two embodiments can withstand radiation sterilization together after installing the Beta valve. After sterilization together, it is convenient to transfer and can meet the requirements of aseptic feeding after docking with the α valve, so as to meet the requirements of rapid, aseptic and closed transfer of products.

[0036] Please refer to Figure 1 and Figure 2 , the bag body 100 is rectangular or T-shaped. When the bag body 100 is rectangular, the Beta valve is disposed on the first sheet 110 or the second sheet 120 of the bag body 100 alone; when the bag body 100 is T-shaped, the Beta valve is disposed on the narrow end of the bag body 100 and is located between the first sheet 110 and the second sheet 120.

[0037] Please refer to Figure 6 The valve cover 300 is provided with a vent hole 330, which is opened inside the valve cover 300, one end of the vent hole 330 extends to the outer end surface of the valve cover 300, and the other end of the vent hole 330 extends to the inner peripheral wall of the valve cover 300, so as to realize the connection between the inner cavity of the valve cover 300 and the outside. The vent hole 330 is a straight hole or an L-shaped hole. When the Beta valve and the α valve are docked, the vent hole 330 will not be unable to open due to the vacuum formed in the cavity formed by the two valves, or the gas pressure in the cavity is too high to be able to dock smoothly, and low-level gas can be prevented from entering the high-level area. Preferably, the diameter of the vent hole 330 is 1 mm.

[0038] Please refer to Figures 3 to 7 The inner circumferential wall of the valve body 200 is provided with an inner annular plate 220, and a plurality of paving notches 230 are opened in the circumferential direction of the inner annular plate 220. A plurality of inner clamping blocks 310 are provided at the lower part of the outer circumferential wall of the valve cover 300, and the plurality of inner clamping blocks 310 pass through the plurality of paving notches 230 one by one. When the transport bag needs to be closed, the plurality of inner clamping blocks 310 on the valve cover 300 are aligned with the plurality of paving notches 230 on the valve body 200, and after the inner clamping blocks 310 pass through the corresponding paving notches 230, the valve cover 300 is rotated so that the inner clamping blocks 310 are clamped on the back side of the inner annular plate 220, thereby realizing the rapid docking of the valve cover 300 and the valve body 200.

[0039] In another embodiment, see Figure 7 The valve cover 300 is also provided with a positioning pin 340 to ensure the directional rotation and positioning of the valve cover and the valve body.

[0040] An annular sealing groove is provided on the upper part of the inner circumferential wall of the valve body 200, and an annular sealing surface 320 is provided on the upper part of the outer circumference of the valve cover 300. The sealing ring is clamped in the annular sealing groove and abuts against the annular sealing surface 320, thereby realizing a sealed connection between the valve body 200 and the valve cover 300 to avoid leakage of the material in the bag body 100.

[0041] The outer peripheral wall of the valve body 200 is provided with an outer annular plate 270, and the outer annular plate 270 is located between the outer clamping block 210 and the connecting sleeve 260. The end surface of the outer annular plate 270 is provided with a plurality of docking holes 271 in the circumferential direction. The docking holes 271 are strip holes that are curved in a conformal manner. By providing a plurality of docking holes 271 on the outer annular plate 270 of the Beta valve, docking with an external handle can be achieved, so that the Beta valve and the α valve can be tightened conveniently.

[0042] Specifically, the sealing ring includes an outer sealing ring 410 and an inner sealing ring 420. A connecting portion 430 is provided between the upper end of the outer sealing ring 410 and the upper end of the inner sealing ring 420. An inclined deformation gap 440 is formed between the outer sealing ring 410 and the inner sealing ring 420. The connecting portion 430 is a thin-walled structure and is prone to bending and deformation. When the outer sealing ring 410 and the inner sealing ring 420 are installed respectively, the outer sealing ring 410 and the inner sealing ring 420 are squeezed and approach each other, the connecting portion 430 is deformed, and the deformation gap 440 gradually becomes smaller, thereby further improving the sealing effect of the sealing ring on the gap between the valve body 200 and the valve cover 300. The annular sealing groove includes a radial sealing groove 240 and an axial sealing groove 250. The outer sealing ring 410 is radially clamped in the radial sealing groove 240, and the inner sealing ring 420 is axially clamped in the axial sealing groove 250. The annular sealing surface 320 is abutted against the inner peripheral wall of the inner sealing ring 420.

[0043] In order to improve the sealing effect of the outer sealing ring 410 and the inner sealing ring 420, a first anti-slip ridge 411 is provided on the outer peripheral wall of the outer sealing ring 410, and a second anti-slip ridge 421 is provided on the outer peripheral wall and the inner peripheral wall of the inner sealing ring 420. In addition, both the first anti-slip ridge 411 and the second anti-slip ridge 421 are accordion edge structures, which have air intake and exhaust functions, ensuring that the gas in the cavity formed by the Beta valve and the α valve is not compressed, which makes it difficult to tighten the valve cover 300 and the valve body 200, or difficult to open due to vacuum formed in the cavity when opening.

[0044] Please refer to Figure 3 and Figure 8 The upper end of the outer peripheral wall of the outer sealing ring 410 is provided with an upwardly inclined first annular flange 450, which extends to the top of the valve body 200. The first annular flange 450 can close the end surface gap between the valve body 200 and the valve cover 300 to improve the sealing effect. The upper end of the inner peripheral wall of the inner sealing ring 420 is provided with a downwardly inclined second annular flange 460, and the annular sealing surface 320 abuts against the inner peripheral wall of the second annular flange 460. The second annular flange 460 can close the lateral gap between the valve body 200 and the valve cover 300 to improve the sealing effect.

[0045] Correspondingly, the angle between the outer peripheral wall of the first annular flange 450 and the outer sealing ring 410 is α 1 , α1 The angle between the inner wall of the second annular flange 460 and the inner sealing ring 420 is α 2 , α 2 It is 20°-40°. When the internal pressure increases, this angle can ensure that the sealing ring strengthens the sealing effect as the internal pressure increases.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
