Installation steps for Marine doors:
1. When the door is opened, the door body drives the connecting rod to move and causes the transmission gear to rotate, driving the rack plunger to move to the right.
2. During the right movement of the plunger, the spring is compressed, and the hydraulic oil in the right chamber is also compressed.
3. The one-way valve ball on the left side of the plunger opens under the action of oil pressure, and the hydraulic oil in the right chamber flows into the left chamber through the one-way valve.
4. After the door opening process is completed, due to the compression of the spring during the opening process, the accumulated elastic potential energy is released, pushing the plunger to the left, driving the transmission gear and door closer connecting rod to rotate, and closing the door.
