Working process

Forward mounting

The main part 1 is down, inner core 4 is up, connect on the trachea through pagoda type interface A1-4 and pagoda type interface B4-2, when compressed air flows to this application through the trachea, gas flows upwards from air vent A1-4, make gas drive steel ball 3 upward movement, make steel ball 3 contact with bell mouth 4-5, at this moment, though steel ball 3 contacts with bell mouth 4-5, but there is the gap confession gas between them and flows through in the locking cylinder from air vent B4-4 through the trachea, thereby reduce the gas flow, reduce the dynamics that the locking cylinder compresses tightly soft sheath, make the locking cylinder can slowly compress tightly soft sheath, prevent that gas flow is too big and will soft sheath crush.

Reverse installation

The inner core 4 faces downwards, the main body 1 faces upwards, the main body is connected to the air pipe through the pagoda type connector B4-2 and the pagoda type connector A1-4, when compressed air flows to the air pipe, the air flows upwards from the air hole B4-4, the air drives the steel ball 3 to move upwards to compress the spring 2, a gap is formed between the air hole B4-4 and the steel ball 3, the air flows into the locking cylinder from the gap through the fluid cavity 1-3, the air hole A1-4 and the air pipe, the function of locking the cylinder fast is achieved, when the air is closed, the air flows back into the cavity 1-3 from the air hole A1-4, the steel ball 3 moves downwards fast under the action of the spring 2 and contacts with the taper hole 4-5, and the air in the cavity 1-3 flows back into the air hole B4-4 from the gap between the steel ball 3 and the taper hole 4-5 slowly, so that the locking cylinder is released slowly, the cylinder can be moved slowly due to the fact that the air is installed on the air pipe in the forward direction, and the air cylinder can be moved quickly, and the cylinders can be controlled to move sequentially.
