It should be understood that the compression limit position refers to a position at which the sealing tape 5 is compressed to a preset value during operation.

In the working process, as shown in fig. 7 (the arrow direction in fig. 7 is the medium flowing direction), if the medium flows from the front of the gate to the back of the gate, the medium pressure acts on the right turned edge, so that the right turned edge is tightly attached to the sealing seat of the gate frame 2, and the higher the pressure is, the tighter the attachment is; if the medium flows to the front of the gate from the back of the gate, the medium pressure acts on the flanging on the left side, so that the flanging on the left side is tightly attached to the sealing seat of the gate frame 2, and the higher the pressure is, the tighter the attachment is.

When the medium pressure is small or the sealing strip 5 is not tightly attached to the individual points of the sealing seat of the gate frame 2 along the length direction, the phenomenon that the sealing medium gradually permeates the flanging at the two sides can occur.
