[0003] The Chinese utility model patent with the announcement number CN203146900U discloses a valve for powder cutting and sealing. The utility model adopts the scheme as follows: a valve for powder, including a valve body, a medium inlet and outlet and a valve cavity are arranged in the valve body, an elastically deformable sealing sleeve is installed in the valve cavity, the sealing sleeve is provided with a medium channel for realizing on-off control by the inner wall of the sealing sleeve being attached or separated after the sealing sleeve is deformed, the two ends of the sealing sleeve are sealed and connected with the inner wall of the valve cavity, the medium channel on the sealing sleeve connects the medium inlet and outlet, the sealing sleeve separates the valve cavity to form a control cavity for controlling the deformation of the sealing sleeve, and the control cavity is located outside the sealing sleeve and is independently arranged with the medium channel. Compared with the prior art, the utility model has the advantages of simple structure, full diameter, no sanitary dead corner and easy cleaning. Since the sealing sleeve in the valve is made of elastically deformable material, when the two sealing sleeves close the medium channel, if the pressure on both sides of the sealing sleeve is unbalanced, the sealing sleeve will be squeezed and deformed, so that powder leakage will occur. Utility Model Content

[0004] Based on the above background, the purpose of the utility model is to provide a sterile powder closed transfer valve with good sealing performance and preventing powder clogging, so as to solve the problems described in the background technology.

[0005] In order to achieve the above-mentioned utility model purpose, the utility model provides the following technical solutions:

In the following detailed description, for ease of explanation, many specific details are described to provide a comprehensive understanding of the embodiments of the present invention. However, one or more embodiments may also be implemented by those skilled in the art without these specific details.

[0033] like Figure 1 As shown, a sterile powder closed transfer valve includes a valve body 1, a sealing groove 2, a valve core 3 and an adjusting rod 4, and flanges 12 are arranged at both upper and lower ends of the valve body 1. The flange 12 can connect the valve body 1 and the pipeline, so that the valve can be conveniently connected to the pipeline system to realize the control and transmission of the powder.

[0034] A sealing groove 2 is arranged inside the valve body 1, and the sealing groove 2 is communicated with the inside of the valve body 1. A valve core 3 is arranged on the opposite side of the valve body 1 to the sealing groove 2. The valve core 3 is slidably matched with the valve body 1 and the sealing groove 2. An adjusting rod 4 is arranged at the end of the valve core 3 away from the sealing groove 2. The adjusting rod 4 is rotatably connected to the valve core 3. The adjusting rod 4 passes through the valve body 1 and is threadably matched with the valve body 1.

[0035] The sealing groove 2 is provided with a sealing sleeve 5 and several elastic members 6. The sealing sleeve 5 is located on the inner side of the sealing groove 2 adjacent to the valve body 1. The sealing sleeve 5 is connected to the sealing groove 2. The two ends of the several elastic members 6 are respectively connected to the sealing sleeve 5 and the sealing groove 2. The several elastic members 6 are linearly arranged at equal distances in the sealing groove 2.

[0036] A motor 7 is arranged outside the valve body 1, and the motor 7 is connected to the valve body 1. A roller 8 is arranged inside the valve body 1, and the height of the roller 8 is higher than the height of the valve core 3. One end of the roller 8 is connected to the inner wall of the valve body 1. The other end of the roller 8 is connected to the output end of the motor 7. A plurality of rotating sheets 9 are arranged on the surface of the roller 8, and the rotating sheets 9 are connected to the roller 8.

[0037] When one end of the valve core 3 is inserted into the sealing groove 2, the valve is in a closed state, and the elastic member 6 is compressed, and the sealing sleeve 5 is close to the valve core 3, so that the valve has a good sealing performance in the closed state to prevent powder leakage. By arranging several elastic members 6 in the sealing groove 2 at equal distances, it can be ensured that the pressure on each elastic member 6 is similar, reducing the possibility of imperfect sealing or leakage due to uneven force, and improving the reliability of sealing. The end of the valve body 1 adjacent to the sealing groove 2 is an arc structure, and the shape of the sealing groove 2 matches the arc structure of the valve body 1. The design of the arc structure can increase the contact area between the sealing groove 2 and the valve core 3, forming a tighter sealing contact, thereby improving the sealing effect and preventing powder leakage.

[0038] like Figure 2 As shown, to open the valve, first rotate the adjusting rod 4. Since the adjusting rod 4 is threadedly matched with the valve body 1 and the adjusting rod 4 is rotatably connected with the valve core 3, the valve core 3 can be pulled out of the sealing groove 2. When the valve core 3 leaves the sealing groove 2, the powder can pass through the valve smoothly. The adjusting rod 4 is provided with a turning handle 11, and the turning handle 11 and the adjusting rod 4 are an integral structure. Through the turning handle 11, the operator can more conveniently manually rotate the adjusting rod 4 to control the opening and closing state of the valve to adjust the flow rate and flow rate of the powder.

[0039] A flow sensor 10 is provided at the lower part of the valve core 3, and the flow sensor 10 is connected to the valve body 1. The flow sensor 10 can monitor the flow velocity and flow rate of the powder to ensure accurate delivery and use of the powder during production or experiment.

[0040] During the process of the valve core 3 moving out of the sealing groove 2, the elastic member 6 extends to prop up the sealing sleeve 5, which can prevent part of the powder from being retained in the sealing groove 2 when passing through the valve. During the period when the powder passes through the valve, the motor 7 is in the starting state, and the motor 7 controls the roller 8 to rotate, so that the rotating piece 9 rotates continuously in the valve body 1, so that the powder can be stirred to prevent the powder from accumulating and clogging in the valve body 1. Several rotating pieces 9 are evenly arranged circumferentially on the roller 8. By evenly arranging the rotating pieces 9 on the roller 8, the powder can flow and distribute more evenly after stirring.

[0041] The implementation principle of the sterile powder closed transfer valve of the utility model is:

[0042] When one end of the valve core 3 is inserted into the sealing groove 2, the valve is in a closed state, and the elastic member 6 is compressed, and the sealing sleeve 5 is tightly attached to the valve core 3, so that the valve has better sealing performance in the closed state to prevent powder leakage.

[0043] To open the valve, first rotate the adjusting rod 4. Since the adjusting rod 4 is threadedly matched with the valve body 1 and the adjusting rod 4 is rotatably connected to the valve core 3, the valve core 3 can be pulled out of the sealing groove 2. When the valve core 3 leaves the sealing groove 2, the powder can pass through the valve smoothly. In the process of the valve core 3 moving out of the sealing groove 2, the elastic member 6 extends to prop up the sealing sleeve 5, which can prevent part of the powder from being retained in the sealing groove 2 when passing through the valve. During the period when the powder passes through the valve, the motor 7 is in the starting state, and the motor 7 controls the roller 8 to rotate, so that the rotating piece 9 rotates continuously in the valve body 1 to stir the powder to prevent the powder from accumulating and clogging in the valve body 1.
