Abstract
The utility model discloses an automobile exhaust recycling valve with a sensor. The automobile exhaust recycling valve with the sensor comprises a valve body. The valve body further comprises a valve seat, a lining and a valve rod assembly, wherein the valve seat, the lining and the sensor are installed in a matched mode. The valve seat and an automobile engine are installed in a matched mode. The valve rod assembly is provided with a sensor assembly which is in butt joint with a wiring harness of a vehicle-mounted computer of an automobile. The sensor assembly further comprises a push rod, a cover plate and a valve switch, wherein the push rod, the cover plate and the valve switch are installed in the matched mode. The valve switch comprises an electric brush and a ceramic plate, wherein the electric brush and the ceramic plate are installed in the matched mode. The automobile exhaust recycling valve with the sensor solves the problems that exhaust gas recirculation (EGR) vacuum valves in the prior art can only control the vacuum degree of a vacuum chamber, and cannot directly control the actual exhaust gas flow entering the vacuum chamber or directly detect whether working condition of the EGR vacuum valve is normal or not.
Description
Technical field
The utility model relates to a kind of automobile exhaust gas recycle valve, especially relates to a kind of recirculation valve for automobile tail gas with sensor.
Background technique
Along with the progress and development of society, environmental issue more and more is subject to people's attention, and country has brought up to important consciousness schedule to pollution of atmosphere, and vehicle exhaust has also been had new environmental protection standard.The vehicle exhaust main component is the particulate matters such as nitrogen oxides (NOx), hydrocarbon (HC), carbon monoxide (CO), sulfur dioxide (SO2), no matter these materials all are harmful to atmosphere or to human body, EGR valve (exhaust gas recirculating valve) in the automobile is exactly the discharging that reduces harmful gas, thereby reaches the purpose of environmental protection.The working principle of EGR vacuum valve switch: car-mounted computer (ECU) is according to air throttle of car aperture and temperature sensor signal, control the degree of vacuum of EGR valve vacuum chamber by vacuum governor, by the poor stem movement that drives of vacuum chamber external and internal pressure, the valve port of EGR valve switch is opened, the waste gas part that motor is discharged sends back to the suction tude of motor again by the inlet hole of EGR valve, mixing enters cylinder afterwards again with ozone, participates in burning.EGR vacuum valve of the prior art can only be controlled vacuum degree in vacuum chamber, can not directly monitor for the actual exhaust gas flow that enters vacuum chamber, and whether can not direct-detection go out the working state of EGR vacuum valve normal.
The model utility content
The technical problems to be solved in the utility model is in order to overcome technological deficiency recited above, a kind of automobile exhaust gas recycle valve with sensor to be provided.
In order to solve technical problem recited above, the utility model is taked following technological scheme:
A kind of recirculation valve for automobile tail gas with sensor, include valve body, described valve body further includes and cooperates valve seat, lining and the valve rod assembly of installing, described valve seat cooperates installation with motor car engine, be equipped with the sensor unit that docks with the wire harness of automobile mounted computer on the described valve rod assembly, described sensor unit further includes and cooperates push rod, cover plate and the valve switch of installing, and described valve switch includes brush and the ceramic plate that cooperates installation.
Described valve rod assembly includes valve rod, packing ring, fixed base, lower levelling plate, lower cover, press table, diaphragm plate, top board, Upper gasket, tack embossing Liu Ding and the upper cap assembly of installing successively.
Described sensor unit is fixed on the upper cap assembly by nut.
Described valve switch is the mechanical valve gate switch.
The new recirculation valve for automobile tail gas with sensor that provides of this practicality has solved EGR vacuum valve of the prior art and can only control vacuum degree in vacuum chamber, can not directly monitor for the actual exhaust gas flow that enters vacuum chamber, and the working state that can not direct-detection goes out the EGR vacuum valve normal problem whether, can either directly monitor the actual exhaust gas flow that enters vacuum chamber, whether the working state that again can direct-detection goes out the EGR vacuum valve is normal.
