Description
Technical field
Engine exhaust emission recirculating system technical field is the utility model is related to, being specially that one kind is new carries displacement
The electric control EGR valve of sensor.
Background technology
Waste gas recycle (English EGR, Exhaust Gas Recirculation abbreviation), its general principle be by
Portion discharge introduces air inlet, improves combustibility, and to reduce NOx formation and discharge capacity in engine exhaust, it is dirty to reduce exhaust
Dye.In engine exhaust-gas recirculating system（Egr system）Middle EGR valve is mainly used in the flow of adjustment control EGR gas, electricity
Dynamic aperture size of the EGR valve by internal direct current motor control air inlet, pneumatic EGR valve then control vacuum by vacuum governor
Size is spent, so that indirect control EGR aperture size makes waste gas be mixed by a certain percentage with fresh air to adjust exhaust gas flow
Cylinder is returned afterwards to be recycled, and to reduce gas in-cylinder combustion temperature and burning velocity, further reduces NOXDischarge capacity.
With to motor vehicle increasingly stricter, the control accuracy and response time requirement of electric EGR valve are required for its emission control
More and more higher；Center-pole causes an impulsive force in motion process with valve element to valve body simultaneously, causes the deformation of valve, influences valve
Service life.Existing EGR valve of the in the market with displacement transducer is all more troublesome when installing displacement transducer.
Utility model content
The technical problem that the utility model solves is to provide a kind of new electric control EGR valve with displacement transducer,
To solve the shortcomings that in above-mentioned background technology.
The technical problem that the utility model solves is realized using following technical scheme：One kind is new to carry displacement sensing
The electric control EGR valve of device, including valve body, displacement transducer and center-pole, the valve element of one end connection of the center-pole, the valve body
Top be provided with it is upper lid and lower cover and institute's displacement sensors, on described lid on be provided with a circular mounting groove, in institute
State and be provided with a spring seat in mounting groove, in the mounting groove equidistantly be provided with four breach, pacify in four breach
Equipped with a fixture, a dead ring is cased with four fixtures.
In the utility model, the bottom of the valve body is put by straight pin installed in valve body.
In the utility model, the spring seat includes top plate and spring.
In the utility model, the fixture includes grip block and little spring, and the head of grip block is arcuate structure.
In the utility model, the dead ring is provided with holding pin, and holding pin is enclosed in the little spring of the fixture.
The beneficial effects of the utility model：Quickly displacement transducer can be installed, be effectively reduced installation
Time；Meanwhile the displacement transducer after installation is firm enough；It is also relatively simple when needing replacing to remove.

Embodiment
In order that technological means, creation characteristic, reached purpose and effect that the utility model is realized are easy to understand, under
Face combines and is specifically illustrating, and the utility model is expanded on further.
Embodiment：As depicted in figs. 1 and 2, a kind of new electric control EGR valve with displacement transducer, including valve body 1, position
Displacement sensor 2 and center-pole 3, the valve element 4 of one end connection of the center-pole 3, the top of the valve body 1 are provided with upper lid 5 with
Lid 6 and institute's displacement sensors 2, the bottom of the valve body 1 are put by straight pin installed in valve body.On described on lid 5
Provided with a circular mounting groove, a spring seat 7 is provided with the mounting groove, the spring seat 7 includes top plate and bullet
It is equidistant in mounting groove described in spring to be provided with four breach, a fixture 8, the fixture are mounted in four breach
8 include grip block and little spring, and the head of grip block is arcuate structure.A dead ring 9, institute are cased with four fixtures 8
State dead ring 9 and be provided with holding pin, holding pin is enclosed in the little spring of the fixture 8.
During installation, fixture 8 is fixed on outside the mounting groove of upper lid 5, then consolidated fixture 8 through the breach on mounting groove
It is scheduled on fixture 8；Then directly displacement transducer is inserted into the mounting groove of upper lid 5.
The advantages of general principle and principal character of the present utility model and the utility model has been shown and described above, one's own profession
The technical staff of industry is it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification
Simply illustrate principle of the present utility model, on the premise of the spirit and scope of the utility model is not departed from, the utility model is also
Various changes and modifications are had, these changes and improvements are both fallen within claimed the scope of the utility model, the utility model
Claimed scope is by appended claims and its equivalent thereof.
