Secondly, the structure of the traditional RTP valve is very complex, and because the traditional RTP valve depends on a rotary compression mode, one main valve needs to be in butt joint with different auxiliary valves, one auxiliary valve also needs to be in butt joint with different main valves, the two valves need to be capable of being generally adapted and reliably compressed many to many, the requirement on the processing precision of the RTP valve is very high, and the problem of unsmooth opening is easily caused in the actual butt joint process. Thirdly, the traditional RTP valve realizes the combined sealing of the main valve and the auxiliary valve by rotating and pressing the sealing strip, so the transfer interface can only be made into a round shape, the caliber is limited by the process and is difficult to be made large, and the size requirement of the interface limited by the size on the material is often very unfavorable in the material transfer process of actual production. In a word, traditional quick transfer valve butt joint inefficiency, and because traditional quick transfer valve receives the restriction of structure complicacy and machining precision, can only adopt circularly in the appearance, also can not accomplish very greatly in the size, and the diameter is no longer than 500mm basically, and is very big to the size restriction of the material that transmits, has seriously influenced its practicality.

An electromagnetically attracted sterile sealing rapid transit valve 1000 according to an embodiment of the present invention will be described with reference to fig. 1 to 3.

As shown in fig. 1 to 3, the electromagnetic attraction type aseptic sealed rapid transit valve 1000 according to the embodiment of the present invention is used to perform aseptic docking between a sealed box and a clean space unit (the clean space unit may be an isolator, a clean room, etc.) for facilitating subsequent aseptic material transfer, wherein the clean space unit has a first interface a (see the labels in fig. 2 and 3), and the first interface a may be understood as a transfer interface for transferring aseptic materials into and out of the clean space unit.

The electromagnetic attraction type sterile sealing rapid transfer valve 1000 comprises a main valve component 1 and an auxiliary valve component 2.

Specifically, the main valve assembly 1 includes a rotatable main valve 10, an electromagnetic actuator 17, and an electrical contact 18. Wherein, the main valve 10 is rotatably installed on the inner sidewall of the wall body 19 of the first port a to open and close the clean space unit, and when the main valve 10 is in a closed state, the main valve 10 is in a sealing connection with the wall body 19; that is, the main valve 10 reliably seals the first port A of the clean space unit, which ensures that the sterile clean environment inside the clean space unit is not contaminated by the outside environment. The electric contact 18 is installed on the outer side wall of the wall body 19, so that when the seal box is in butt joint with the outer side wall of the wall body 19, the electric contact 18 is in contact with the seal box to enable a loop of the electronic control module to be conducted, and then the electronic control module controls corresponding functional components to act. The electrical contacts 18 may be semi-circular, cylindrical or other shapes, and may be selected according to the actual needs. An electromagnetic actuator 17 is installed on the main valve 10, and the electromagnetic actuator 17 is mainly used to generate a magnetic force, which includes an attractive force required during the coupling of the hermetic container to the clean space unit and a repulsive force required during the decoupling of the hermetic container from the isolation container.

The sub-valve assembly 2 includes a sub-valve 20 and a moving valve 21. The auxiliary valve 20 is fixed on the sealed box, wherein the auxiliary valve 20 can be understood as a part of a structure directly formed on the sealed box or can be understood as a separate part which is fixed on the sealed box in a sealing way; the secondary valve 20 has a second port B (see the references in fig. 2 and 3) communicating with the capsule, which can be understood as the transfer port of the sterile material in and out of the capsule. The moving valve 21 has a first position I and a second position II (refer to the labels in fig. 1), the first position I is located in the second port B, the second position II is located in the main valve 10, when the moving valve 21 is in the first position I, the moving valve 21 is located in the second port B and the moving valve 21 and the auxiliary valve 20 are tightly sealed, so as to ensure that the clean environment inside the sealed box is not polluted by the outside environment; when the movable valve 21 is at the second position II, the movable valve 21 is located in the main valve 10, and the movable valve 21 and the main valve 10 are locked and sealed, so that it can be ensured that contaminants in the space environment between the main valve 10 and the movable valve 21 (i.e. the middle space after butt-sealing) cannot enter the sealed box and the clean space unit, and the clean environment inside the sealed box and the clean space unit can be ensured without killing the space environment between the main valve 10 and the movable valve 21, and meanwhile, because the space environment between the main valve 10 and the movable valve 21 does not need to be killed, the butt-joint efficiency of the sealed box and the isolation is greatly improved, i.e. the aseptic sealing butt-joint speed is high.

The aseptic separation process of the sealing box and the clean space unit comprises the following steps: under the condition that the first interface A is communicated with the second interface B and the main valve 10 is in an opening state, when the seal box needs to be separated from the clean space unit, the electric control module firstly controls the main valve 10 to rotate from the opening state to a closing state, so that the first interface A is disconnected from the second interface B; the electric control module controls the moving valve 21 to be released from the main valve 10, and further controls the electromagnetic actuator 17 to generate a repulsive force to the moving valve 21, the repulsive force enables the moving valve 21 to move back to the first position I from the second position II, when the moving valve 21 returns to the first position I, the electric control module controls the moving valve 21 and the auxiliary valve 20 to be locked and sealed, and finally the electric control module controls the auxiliary valve 20 to be unlocked from the wall 19, and at the moment, the seal box can be separated from the wall 19. During the detachment of the sealed box from the clean space unit, the clean space unit and the sealed box are still in a sterile and clean environment. That is, the process of aseptically separating the sealed box and the clean space unit is exactly the reverse of the process of aseptically docking the sealed box and the clean space unit.

Secondly, the interface shape and size have wide application range. The process of butting and separating the sealing box and the clean space unit is not required to be butted and separated by a rotary pressing sealing mode in the prior art, but an electric control module is adopted to control corresponding functional parts to act to realize locking and sealing of the locking mechanism, so that the interface can be in various shapes such as a circle, an ellipse, a square, a pentagon, a hexagon and the like, meanwhile, a common sealing ring is adopted to perform pressing sealing in a sealing principle, the requirement on the processing precision of the main valve 10 and the auxiliary valve 20 is not high, the size of the interface can be very large, the size of the interface can be much larger than that of the interface in the prior art, the length and the width (diameter) of the interface are 1000mm, and the application and popularization are facilitated.

Wherein, one locking mode is as follows: a first locking mechanism (here, the first locking mechanism is not shown, and may be similar in structure to a third locking mechanism 25 hereinafter, and may be referred to as the third locking mechanism 25 hereinafter) is provided between the moving valve 21 and the inner peripheral wall of the cavity 1021 of the main valve 10, and includes a first locking hook mounted on the inner peripheral wall of the cavity 1021 and a second locking hook formed on the moving valve 21; when the moving valve 21 is located at the second position II, the electronic control module controls the first lock hook to hook the second lock hook, so as to lock the moving valve 21, so that the moving valve 21 is hermetically connected with the third seal ring 13; when the moving valve 21 needs to move to the first position I, the electronic control module controls the first locking hook to extend out, so that the first locking hook and the second locking hook are released.
