Embodiment Construction
[0044] The inventor found through research that, figure 1 The shown control valve utilizes the iron core 520 to absorb the suction sheet 400 during use. When the first end 410 of the suction sheet 400 moves toward the iron core 520 , it experiences relatively large gas resistance. After the coil 510 is powered off, there is hysteresis in the demagnetization of the iron core 510 , so even if the coil 510 is powered off, the iron core 520 still has a partial attraction force on the suction sheet 400 . The residual magnetic force of the iron core 520 is a kind of resistance when the suction sheet 400 is reset. The resistance of the air slows down the speed at which the suction piece 400 moves toward the iron core 520; the residual magnetism slows down the speed at which the suction piece 400 resets, so figure 1 The suction piece 400 running speed of the control valve in is too slow, can only reach 120 times per second.

The invention discloses a multi-arm control valve, which comprises a valve body, a connecting shim plate and more than two electromagnetic components and is characterized by comprising more than two suction pieces and more than two resetting springs, wherein the opening and closing of a first through hole is controlled by each suction piece; each electromagnetic component and each resetting spring form a group to control the movement of each suction piece; each resetting spring applies force to each suction piece, so that each first through hole is closed by the first end of each suction piece; when a coil is powered on, the first end of each suction piece can be moved, so that each first through hole is opened, and each resetting spring generates elastic deformation force; and through the elastic deformation force generated by each resetting spring, the first end of each suction piece is reset to a position where each first through hole is closed when the coil is powered off. By the multi-arm control valve and a fuel supply control valve for a vehicle, the reciprocating movement speed of the suction pieces is high, and the through holes can be opened and closed for 380 times per second. The multi-arm control valve and the fuel supply control valve are particularly suitable for gas vehicles.
Description
technical field [0001] The invention relates to a multi-arm control valve and a vehicle fuel supply control valve. Background technique [0002] Automobiles and other oil-powered, pneumatic and other power vehicles use electromagnetic components to control the opening and closing of the second oil and gas through holes. figure 1 Shown is a structural schematic diagram of a multi-arm control valve, which includes a valve body 100 , and the valve body 100 is provided with a feed pipe 110 and a valve cavity 120 . The feed pipe 110 communicates with the valve cavity 120 . More than two electromagnetic components 500 are arranged in the valve cavity 120 . The electromagnetic assembly 500 includes a coil 510 and an iron core 520 . A connection pad 200 is installed on the valve body 100 . The connection pad 200 is provided with four first through holes 210 . The four first through holes 210 are all in communication with the valve cavity 120 . Four accommodating holes 220 are ...
