Abstract
The invention provides a diesel engine throttle valve which comprises a throttle valve body. The throttle valve body is of a hollow barrel-shaped structure, an electric push rod is arranged in the throttle valve body, one end of the electric push rod is provided with a butterfly-shaped valve body, and opening and closing of air flow in the throttle valve body are achieved by controlling opening and closing of the butterfly-shaped valve body through the electric push rod; the throttle valve further comprises a pressure sensor which detects negative pressure in a suction pathway on the downstream side of the throttle valve. The diesel engine throttle valve has the advantages that the mode of pushing a valve body in a traditional throttle valve is transformed, opening and closing of the valve body are achieved by means of the mode of combining the pressure sensor and the electric push rod; the throttle valve pressure sensor detects the negative pressure in the suction pathway on the downstream side of the throttle valve and feeds back a pressure signal to the electric push rod, and opening and closing of the valve body are achieved. Accordingly, pressure situations in the throttle valve can be fed back in real time, and the working precision of the throttle valve is improved.
Description
Technical field
The present invention relates to Diesel Engine Technique Field, be specifically related to use for diesel engine throttle valve.
Background technique
Throttle valve is by changing throttling cross section or chock length to control the valve of fluid flow.Throttle valve then be may be combined with into one-way throttle valve with one-way valve parallel connection.Throttle valve and one-way throttle valve are easy flow control valves, and in hydraulic system with constant displacement pump, throttle valve and relief valve coordinate, and can form three kinds of Metering Flow Control Circuits, i.e. in-line Metering Flow Control Circuits, oil circuit Metering Flow Control Circuits and bypass throttling speed governing system.Throttle valve does not have flow reverse feedback function, can not compensate the speed that caused by load variations unstable, generally only little or to the less demanding occasion of speed stability for load variations.
Generally in prior art adopt line traffic control mode to control throttle valve to open and close and change into electric signal by the instructions of input and control throttle valve state, due to needs manual control so its efficiency and feedback are all bad.Therefore need to invent a kind of Novel diesel engine throttle valve with effect of change diesel engine throttle valve.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of diesel engine throttle valve, its objective is, by setting up Electronic control technology to improve the using effect of diesel engine throttle valve.
For achieving the above object, technological scheme of the present invention is as follows:
