Description

Technical Field

[0001] The utility model relates to the technical field of gas-liquid separation equipment, in particular to an automatic exhaust valve and a degassing filter. Background Art

[0002] The degassing filter is one of the auxiliary equipment of the flow meter, and the automatic exhaust valve is one of the important parts of the degassing filter. The working principle of the degassing filter is as follows: when the liquid flows through the degassing filter, the impurities in the liquid are filtered by the filter screen. After the clean liquid enters the inner cavity of the degassing filter, the gas contained in the liquid rises to the upper part of the degassing shell to form a gas space. As the amount of gas increases, the gas space continues to expand, and the liquid level continues to drop. The float drops with the liquid level under the action of its own weight, and drives the connecting rod mechanism to move, so that the valve mouth opens and discharges part of the gas. As the gas is discharged, the liquid level will rise rapidly, and the float will also rise, and drive the connecting rod mechanism to move in the opposite direction, closing the valve to prevent the liquid from overflowing. When the gas accumulates to a certain extent, the exhaust valve will be reopened to exhaust, and the cycle will be repeated to achieve the purpose of exhaust.

[0003] At present, most automatic exhaust valves use a floating ball to drive the connecting rod mechanism to move to achieve the lifting and lowering of the floating ball, and then close or open the valve port through the floating ball, such as the automatic exhaust valve and degassing filter provided by Chinese patent CN219655396U, which includes a valve body and a valve body connecting member and other structures, wherein the valve body includes a floating ball, a valve stem and a floating ball connecting block, and the valve stem is connected to the top of the floating ball through the floating ball connecting block; the valve body connecting member includes a first hinge block, a first connecting rod, a second connecting rod and a second hinge block that are hinged in sequence, and the second hinge block is arranged on the floating ball connecting block. When the liquid level rises, the floating ball moves upward with the liquid level, and drives the valve stem, the floating ball connecting block, the first connecting rod, the second connecting rod and the second hinge block to move upward until the valve stem is inserted into the bottom end of the first exhaust channel to achieve the closure of the valve port. When the automatic exhaust valve closes the valve mouth, the float needs to drive multiple components such as the valve stem, the float connecting block, the first connecting rod, the second connecting rod and the second hinge block to move. Due to the large number of components and the large overall weight, the float cannot float to the correct position in certain low-density media and cannot achieve effective sealing, causing the liquid inside the container to easily leak out through the exhaust hole.
