Problems solved by technology

At present, many liquid traps are configured as part of the Venturi pump pressure reducer. Most of the liquid traps used in automobiles are designed and installed vertically, and the interior is blocked by multiple trapping partitions. The current technology is prone to gas-liquid Blockage, resulting in a decrease in the internal flow rate of the Venturi pump, which affects the adsorption of the Venturi pump and needs to be optimized

Abstract

The invention discloses an active discharge liquid trap for a fuel system and relates to the field of fuel system traps. The active discharge liquid trap comprises fixed rings and a trapping bin. A gas outlet and a liquid outlet are symmetrically formed in the right end face of the trapping bin. A fluid inlet is formed in the position, close to the left end face, of the top of the trapping bin. After the liquid enters the trapping bin, a lifting sealing plate is driven to sink under the action of the dead weight of the liquid and is separated from a fixed sealing plate, so that fuel fluid canbe drained into the bottom of a main body of the trapping bin. In addition, a sealing mechanism transfers power to a cutoff mechanism and a downward pressing mechanism, the cutoff mechanism unlocks acontrol mechanism, the downward pressing mechanism enables the control mechanism to start an air guide mechanism and make upwind manufacturing, the trapping of particle trapping plates is facilitated,and then the air guide mechanism synchronously drives a flow guide mechanism to rotate through a second transmission mechanism, so that the drainage speed of the fluid is increased, the blockage of gas and liquid is avoided, the effect of the trap on a Venturi pump is improved, and the situation that the adsorption effect of the Venturi pump is affected due to the blockage in the trapping bin isprevented.

Description

technical field [0001] The invention relates to the field of fuel system traps, in particular to an active drain liquid trap for fuel systems. Background technique [0002] Fuel vapor emission control systems have become increasingly sophisticated, in large part to comply with environmental and safety regulations imposed on manufacturers of gasoline-powered vehicles. As the overall system becomes more complex, so does the complexity of the individual components within the system. Certain regulations affecting the gasoline powered vehicle industry require storage of fuel vapor emissions from the ventilation system of the fuel tank during operation of the engine. In order for the entire vapor emission control system to continue to function for its intended purpose, the stored hydrocarbon vapors must be periodically purged during operation of the vehicle. In addition to managing vapor emissions, some fuel systems include liquid traps. At present, many liquid traps are config...
