Description
Technical Field
The utility model belongs to the technical field of automobile parts, concretely relates to electromagnetic type carbon tank valve.
Background
To prevent environmental pollution and improve fuel economy from gasoline vapors in the vehicle fuel tank, modern vehicle engine management systems control the fuel vapors. The canister solenoid valve is one of the key components in the fuel vapor purge control subsystem. In the fuel vapor purge control system, fuel vapor in the fuel tank is adsorbed by activated carbon in the canister. According to the actual working state of the engine, the electronic control module controls the on-off of the electromagnetic valve by outputting a pulse width signal, and fuel steam is sucked and emitted by depending on the vacuum degree in the air inlet manifold
And finally, the air enters an engine cylinder for combustion in an air inlet channel of the engine. Therefore, the purposes of cleaning fuel steam in the activated carbon tank and controlling fuel evaporation pollution emission are achieved. However, the current canister solenoid valve cannot control the flow of fuel vapor well, so that improvement on the prior art is urgently needed to meet the use requirement.

As shown in the figure, the device comprises a 1-lower shell, a 2-sleeve assembly, a 3-vacuum tube, a 4-secondary plate assembly, a 5-spring, a 6-filter screen, a 7-air inlet pipe, an 8-coil assembly, a 9-limiting shaft, a 10-sleeve, an 11-coil lug and a 12-rubber mounting sleeve.
Detailed Description
The principles and features of the present invention are described below in conjunction with the following examples, which are set forth only for the purposes of explanation and are not intended to limit the scope of the present invention.
As shown in fig. 1-3, an electromagnetic type carbon canister valve comprises a lower casing 1, a sleeve pipe assembly 2 and a vacuum pipe 3, wherein a filter screen 6 is arranged between the lower casing 1 and the sleeve pipe assembly 2, an air inlet pipe 7 is arranged on the lower casing 1, the sleeve pipe assembly 2 comprises a coil assembly 8, a coil lug 12 is arranged on the coil assembly 8, the coil assembly 8 is arranged in a sleeve pipe 11, a limiting shaft 9 is arranged in the coil assembly 8, one end of the limiting shaft 9 is riveted with the sleeve pipe 10, a spring 5 is arranged in a central hole of the limiting shaft 9, the limiting shaft 9 is connected with a rubber part in a secondary plate assembly 4, and the lower casing 1 is connected with the vacuum pipe 3.
For the convenience of installation, the outer side of the lower shell 1 is provided with a rubber installation sleeve 12.
In order to ensure reliable connection, the lower shell 1 is welded with the vacuum tube 3.
In order to ensure strength and sealing performance, the lower shell 1 and the air inlet pipe 7 are integrally formed.
The utility model discloses a realize through following mode: during the use, for the coil circular telegram, secondary plate subassembly 4 moves to spacing axle 9 direction under the effect of electromagnetic force, and secondary plate subassembly 4 leaves vacuum tube 3, and the carbon tank valve is opened, and oil gas gets into and passes the valve body from the intake pipe 7 of inferior valve 1 and flows into vacuum tube 3, discharges from the gas vent of vacuum tube 3 at last. When the coil is powered off, the electromagnetic force disappears, the secondary plate assembly 4 moves towards the vacuum tube 3 under the action of the elastic force of the spring 5, and the rubber piece on the secondary plate assembly 4 blocks the exhaust port of the vacuum tube 3, so that gas is cut off, and the carbon tank valve is closed.
The utility model discloses utilize the electrical coil to produce the design of magnetic field principle and form, drive the valve through the electromagnetic force and open, close, the utility model discloses a normal close formula. The fuel vapor flow delivered to the intake manifold from the canister is controlled by an engine Electronic Control Module (ECM) by adjusting the width of an electrical pulse input to a canister control solenoid coil based on the actual operating conditions of the engine.
The protection scope of the present invention is not limited to the technical solution disclosed in the specific embodiment, and all the modifications, equivalent replacements, improvements, etc. made by the technical entity of the present invention to the above embodiments all fall into the protection scope of the present invention.
