The invention discloses an oil pipe pressure balance control valve, which comprises a control valve body, a balance device and a noise reduction sleeve. The control valve body is provided with a spool chamber, and its side is provided with an air inlet, and its bottom is provided with a The air outlet connected to the valve core chamber; the balance device is arranged in the valve core chamber, the balance device includes a guide rod, a permanent magnet, a valve core and an electromagnetic device, the bottom of the guide rod is fixed in the valve core chamber and its top passes through the air inlet and Extending to the outside of the air inlet; the valve core includes valve block 1, valve block 2, valve 3 and valve block 4, and valve block 1, valve block 2, valve 3 and valve block 4 are movably socketed on the guide from left to right On the rod, and a permanent magnet is installed on the valve block 4; the electromagnetic device includes an iron core and a energized coil, the energized coil is wound outside the iron core, and the iron core repels the permanent magnet installed on the valve block 4 after the energized coil is energized. The present invention is simple in structure, easy to use, and can play the role of pressure regulation and control.
Description
technical field [0001] The invention relates to the field of pressure control valves, in particular to an oil pipe pressure balance control valve. Background technique [0002] The carbon canister is set up to absorb excess fuel vapor in the fuel tank. The interior of the carbon canister is filled with highly absorbent activated carbon. The fuel tank and the carbon canister are connected by pipes. The working state of the carbon canister is controlled by the carbon canister control valve. The working principle of the carbon tank control valve is that when the engine is turned off, gasoline vapor and fresh air are mixed in the tank and stored in the activated carbon tank. When the engine starts, the control valve installed between the carbon tank and the intake manifold opens , The gasoline vapor in the activated carbon tank is brought into the cylinder by the clean air under the vacuum of the intake pipe to participate in combustion. This not only reduces emissions, but als...
