Abstract
The utility model provides a throttle valve of a diesel engine. The throttle valve comprises a throttle valve body which is of a hollow cylindrical structure. An electric push rod is arranged in the throttle valve body, one end of the electric push rod is provided with a butterfly valve body, and the electric push rod controls the butterfly valve to be opened and closed so as to control flowing of air flow in the throttle valve body. The throttle valve further comprises a pressure sensor, and the pressure sensor detects negative pressure in an air suction path on the downstream side of the throttle valve. The throttle valve of the diesel engine is characterized in that the valve rod pushing mode in a traditional throttle valve is changed, and the valve body is opened and closed with the combination of the pressure sensor and the electric push rod. The pressure sensor of the throttle valve detects the negative pressure in the air suction path on the downstream side of the throttle valve and feeds a pressure signal to the electric push rod so as to open and close the valve body. In this way, the pressure situations in the throttle valve can be fed back in real time, and the work precision of the throttle valve is improved.
Description
Technical field
The utility model relates to Diesel Engine Technique Field, is 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.By throttle valve and one-way valve parallel connection capable of being combined become one-way throttle valve.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 being caused by load variations unstable, generally only little or to the less demanding occasion of speed stability for load variations.
In prior art general adopt line traffic control mode control throttle valve to open and close to change into electric signal by the instructions of input control throttle valve state, so due to its efficiency of needs manual control and feedback all bad.Therefore need a kind of Novel diesel engine of model utility throttle valve effect with change diesel engine throttle valve.
