Structure principle:
The operation box is mainly composed of the main box and the front chamber. If the user has other special requirements, can also be based on the needs of the design or transformation.
There are two or more glove operation interfaces on the main box, which are distributed in the front or both sides of the box, so that the operation box can be operated by one or several people at the same time, improving the use efficiency of the box. In addition, in front of the box or before and after can have an observation window, the operator can clearly observe the operation process in the box, so that the operation process more intuitive display in front of the operator.
There are several valves on the box of the operating box, which can be used by users according to their needs. The inside and outside of the valve are connected with a water nozzle, which can be accessed in case of water or ventilation.
The front compartment is a transition between the main box and the exterior, and is composed of two sealed doors and a valve and a KF-25 joint as well as a chamber. Inside and outside the two doors can effectively isolate the main box and the outside of the contact, so that the box inside and outside things can be easier to enter and exit. Thus solving the problem of repeatedly vacuuming and inflating the main box.
