Description
Technical Field
The utility model relates to the technical field of automobile oil valve valves, in particular to a pressure-adjustable air tightness testing device.
Background
The automotive fuel valve is a valve for controlling the supply of automotive fuel. Fuel valves in automotive fuel systems are mainly of two types: the fuel injection valve is positioned in the fuel injector and used for controlling the injection quantity and injection time of the fuel, and the automobile fuel valve plays a key control role in a fuel system, so that the fuel supply and injection accuracy can be ensured, and the performance and fuel economy of the engine can be improved.
The working principle of the automobile oil valve is to control the flow of oil flow by controlling the on-off state of the oil valve. When the oil valve is closed, the oil flow cannot pass through the valve, and the supply of fuel is prevented; when the oil valve is open, the flow of oil can smoothly pass through the valve to supply fuel to the fuel system.
However, when the existing automobile oil valve works, fuel can enter the interior of the automobile oil valve, at the moment, the air tightness of the interior of the automobile oil valve ensures that the oil valve cannot leak when entering the fuel, but the space inside the existing automobile oil valve is fixed, so that the accurate air tightness effect of the oil valve cannot be obtained; in view of this, we propose an adjustable pressure tightness test device.
