Description

Technical Field

[0001] The utility model relates to a novel sanitary multi-pass block. Background Art

[0002] In the pipeline construction in the biomedical field, due to the high cleanliness requirements in this field, there must be no dead corners in the pipeline. Therefore, the number of pipeline joints used in the same section of pipeline should be minimized. However, since the connection of pipes of different specifications in the pipeline inevitably uses reducers, this results in a high number of connection points. The multi-channel reducer pipe joints in the prior art are difficult to process due to space limitations. Generally, at most two reducer channels are set, which cannot further meet the requirements of multiple channels. Summary of the invention

[0003] The problem to be solved by the utility model is to provide a novel sanitary multi-pass block, which is used in pipeline construction in the pharmaceutical production industry and overcomes the shortcomings of the prior art.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: a new type of sanitary multi-pass block, including a block with a rectangular or square cross-section, the surface of the block has six planes, at least three of the six planes have reducing short tubes, the reducing short tubes on the block are all connected to the interior of the block, and the inner diameters of at least two of the reducing short tubes are not equal.

[0005] Optionally, the block has the reducing short tubes on two opposite surfaces.

[0006] Optionally, the inner diameters of the reducing short tubes on two opposite surfaces are equal and the two axes coincide with each other.

[0007] Optionally, the inner diameters of the reducer short tubes on two opposite surfaces are not equal, the two axes are parallel to each other, and the cross section of the reducer short tube with a smaller inner diameter is inscribed in the cross section of the reducer short tube with a larger inner diameter.

[0008] Optionally, the reducing short tubes are provided on two adjacent surfaces of the block.

[0009] Optionally, the inner diameters of the reducing short tubes on two adjacent surfaces are equal, the two axes are perpendicular to each other and are located in the same plane, and the connection between the two reducing short tubes has a smooth transition.

[0010] Optionally, the inner diameters of the reducer short tubes on two adjacent surfaces are not equal, the two axes are perpendicular to each other and are located in the same plane, and the outer edge of the cross section of the connection between the two reducer short tubes is an arc tangent to the outer edge of the cross section of the two reducer short tubes.

[0011] The advantages and positive effects of the utility model are as follows: due to the adoption of the above technical solution, the structural design is reasonable, and the problem that the multi-channel reducer is difficult to process due to limited space during design and construction is solved. In the cleaning system, the distance 3D (D is the inner diameter of the pipeline) between the center of the ball valve and the parallel pipe wall is considered to be clean. The connection of this block makes it easier to achieve the 3D standard in the sanitary level, avoiding mutual interference between the actuators of the ball valve, and can minimize the number of reducers and tee joints in the same section of the pipeline.

This application provides three specific implementations: Specific implementation method one:

[0025] like Figure 1 As shown, in this embodiment, reducer short tubes are provided on five of the six surfaces, namely the first reducer short tube 2, the second reducer short tube 3, the third reducer short tube 4, the fourth reducer short tube 5 and the fifth reducer short tube 6. The inner diameters of the five reducer short tubes are all different. The first reducer short tube 2 and the second reducer short tube 3 are located on two opposite surfaces on the block 1, and the third reducer short tube 4 and the fourth reducer short tube 5 are located on the other two opposite surfaces on the block 1. Specific implementation method 2:

Specific implementation method three:

[0029] like Figure 3As shown, in this embodiment, a first reducing short tube 2 and a second reducing short tube 3 are respectively arranged on two opposite surfaces of the block 1, and a third reducing short tube 4 is arranged on a surface adjacent to the two opposite surfaces, and the inner diameters of the three reducing short tubes are not equal.

[0030] In order to make the passage in the block 1 have no dead angle, two reducing short pipes with different inner diameters located on two opposite surfaces of the block 1 are provided, such as Figure 3-2 As shown in the figure, the axes of the two reducing short pipes are parallel to each other.

[0031] For two reducing short pipes with different inner diameters located on two adjacent surfaces of the block 1, such as Figure 2-2 , Figure 2-3 As shown, the axes of the two reducer short tubes are perpendicular to each other and are located in the same plane. The external deformation of the cross section at the connection of the two reducer short tubes is an arc, and the arc is tangent to the outer edges of the cross sections of the two reducer short tubes.
