Information

The quick exhaust valve uses the principle of the buoyancy effect of water on the stainless steel floating ball. When the water level of the exhaust valve rises, the floating ball will be affected by the buoyancy of the water while exhausting, and it will automatically rise until it reaches the exhaust port. When the sealing surface is connected, the ball will automatically close when there is a certain pressure. When the water level in the valve drops, the ball will drop as the water level drops. At this time, a large amount of air is injected into the pipe through the exhaust port and installed on the pipe. , Use the inertia of the water to the floating ball to automatically open/close the exhaust port.

Quick exhaust valve

When the pipeline is running, the floating ball stops at the bottom of the bowl and a large amount of exhaust is exhausted. After the air in the pipe is discharged, the water flows into the valve. The bowl reacts to the float and closes the float. When the pipeline is running normally, a small amount of gas is concentrated in the valve to a large extent. When the water level in the valve drops and the float ball drops, when the pump stops, negative pressure is generated at any time, and the float ball drops at any time, and a large amount of air intake ensures the safety of the pipeline. When the quick exhaust valve is in the exhaust state, the pontoon pulls one end of the lever downward due to gravity. At this time, the lever is in an inclined state. When there is a gap in the contact part of the lever and the exhaust hole, the air passes through the gap and passes through the exhaust hole. When the air is discharged, the water level rises, and the float floats upward under the buoyancy of the water. The sealed end face on the lever gradually presses the exhaust hole until the entire exhaust hole is completely blocked, and the quick exhaust valve is completely closed at this time.

The three valve ports of the quick exhaust valve are represented by the letters p, a, and t respectively. P is connected to the air source, a is connected to the executive part, and t is connected to the atmosphere. When p has compressed air input, the valve body is pushed to move to the right, p and a pass, and p that supplies air to the actuator is not input, the gas of the actuator moves the valve body to the left through a, blocking the passages of p and a, At the same time, the a and t channels are opened, and the gas is quickly discharged through t. The quick exhaust valve is often installed between the reversing valve and the cylinder, so that the exhaust of the cylinder is not quickly discharged through the reversing valve. Speed ​​up the reciprocating movement of the cylinder and shorten the working cycle.
