(Summary description)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 automatically rise under the buoyancy of the water while exhausting, until it contacts the sealing surface of the exhaust port. The ball will automatically close when it is pressed. When the water level in the valve drops, the ball will drop as the water level drops. At this time

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 automatically rise under the buoyancy of the water while exhausting, until it contacts the sealing surface of the exhaust port. The ball will automatically close when it is pressed. 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 will be injected into the pipeline through the exhaust port. After being installed on the pipeline, the inertia of the water on the floating ball will be used to automatically open/close the exhaust port. When the pipeline is running, the floating ball stops at the bottom of the bowl to exhaust a lot. When the air in the pipe is exhausted, the water rushes into the valve, passes through the bowl and reacts to the float, so that the float is closed. When the pipeline is in normal operation, If a small amount of gas will be concentrated in the valve to a considerable extent, the water level in the valve will drop, the float ball will drop, and the gas will be discharged from the small hole. If the pump stops, negative pressure will be generated at any time, and the float ball will drop at any time to ensure a large amount of inhalation. The pipeline is safe.

In the exhaust state, the pontoon pulls down one end of the lever due to gravity. At this time, the lever is in an inclined state, and there is a gap in the contact part between the lever and the exhaust hole, and the air is discharged from the exhaust hole through this gap. As the air is discharged, the water level rises, and the float floats upward under the buoyancy of the water. The sealed end face of the lever gradually presses on the exhaust hole until the entire exhaust hole is completely blocked, and the exhaust valve is now completely in position. Closed state.

The quick exhaust valve has three valve ports which are represented by the letters P, A and T respectively. P is connected to the air source, A is connected to the actuator, and T is open to the atmosphere. When P has compressed air input, push the spool to move to the right and P connects to A to supply air to the actuator; when P has no compressed air input, the actuator is in The gas moves the valve core to the left through A, blocking the P and A passages, and simultaneously opens the A and T passages. The gas is quickly discharged through T. The quick exhaust valve is included in the automatic selection. The quick exhaust valve is often installed in Between the reversing valve and the cylinder, the exhaust of the cylinder is quickly discharged without passing through the reversing valve, thereby accelerating the reciprocating speed of the cylinder and shortening the working cycle.
