Embodiment Construction

[0018] The present invention will be further described below in conjunction with accompanying drawing.

[0019] Throttle valves driven by DC motors, such as figure 1 As shown, it includes a DC motor 2 fixed on the sensor 9 through the motor housing 1, the motor gear 3 is installed on the DC motor 2, the motor gear 3 meshes with the large gear 5 of the three driven gears 4, and the three driven gears 4 The pinion 6 meshes with the transition gear 8, and the three driven gears 4 are evenly distributed on the sensor 9 through the gear shaft 7 (such as figure 2 shown), the transition gear 8 and the valve stem 10 are installed on the valve body 11 as a whole, and the valve plate 12 is installed on the valve stem 10 .

[0020] like image 3 As shown, the chip 17 on the sensor 9 is placed directly above the magnetic steel 18 on the transition gear 8, and the sensor 9 can read the position signal of the magnetic steel 18 on the transition gear 8 through the chip 17 of the sensor 9,...

Abstract

The invention discloses a throttle valve driven by a direct-current motor. The throttle valve comprises the direct-current motor (2), a motor gear (3), driven gears (4), a transition gear (8), a valve stem (10), a valve block (12), a sensor (9), a valve body (11), a limit piece (16) and a torsional spring (15), wherein the direct-current motor (2) is fixed on the sensor (9) through a motor shell (1), the motor gear (3) is directly mounted on the direct-current motor (2), a chip (17) on the sensor (9) reads the position signals of the valve block (12) through magnetic steel (18) on the transition gear (8), the transition gear (8) is integrated with the valve stem (10) and the valve block (12), and the transition gear (8) rotates to drive the valve block (12) through the valve stem (10), so that the throttle valve can be opened and closed. The throttle valve has the advantages that the direct-current motor can drive by a simple transmission way to open and close the valve block of the throttle valve, and the throttle valve is small in size, easy to mount and arrange, high in control accuracy and short in response time, and the different opening positions of the valve block can be accurately controlled.

Description

technical field [0001] The invention relates to a throttle valve, in particular to a novel throttle valve driven by a DC motor. Background technique [0002] At present, the domestically produced throttle valve driven by a DC motor has the characteristics of complex transmission mechanism and large volume, which is not conducive to the spatial layout of the engine. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a simple and effective transmission method to drive the opening and closing of the throttle valve plate through the DC motor through a simple transmission method, which is small in size, easy to install and arrange, high in control precision and short in response time , and can precisely control the valve in different opening positions. [0004] Technical scheme of the present invention is: [0005] A throttle valve driven by a DC motor, including a DC motor, motor gear, driven gear, transition gear, va...
