Description
?
Technical field:
The invention belongs to the internal-combustion engine electronic control field, relate to a kind of mechanism for engine exhaust control, relate in particular to a kind of embedded combined electric EGR valve.
Background technique:
Waste gas recirculation (EGR) is a kind of by the emission control measure of countries in the world extensive use, and for reducing the NOx discharging, effect is extremely obvious.The electronic EGR valve of domestic production at present drives based on direct current generator and stepper motor, and its principle is the linear reciprocating motion that rotatablely moving of motor is converted into valve rod.The structural type of electronic EGR valve mostly is and outreaches integrated type, the overall profile size is generally bigger than normal, and in the general very compact confined space that is arranged in under-cab of motor, intert again around the motor and arrange a lot of pipelines, circuit etc., this arranges the space of EGR valve on motor and is very limited, according to the different engine displacement different EGR valve of needs configuration again.
In this case, advantages such as the structure of embedded EGR valve is small and exquisite, layout compactness just seem obvious especially, and it can be inserted inlay in the engine pipelines, thereby arranges simply, conserve space.But the present domestic embedded knockdown EGR valve that also do not have can not effectively utilize the driving mechanism of EGR body interior, thereby increase the manufacture cost of different series EGR valve.
Summary of the invention:
Technical problem to be solved by this invention provides a kind of embedded combined electric EGR valve, by changing the needs that different interior inlays and spool can satisfy the different displacements motor, avoid the installation complexity of integrated type EGR valve, avoided redesigning new EGR valve again, further improved the versatility of EGR valve.
Technological scheme of the present invention is: embedded combined electric EGR valve, comprise: main valve body lid, set screw, first bolt, locating stud, pad, second bolt, main valve body, top cap, interior inlay, spool, guiding copper sheathing, valve spring, spring seat, split washer, outside framework oil seal, valve rod, the main valve body lid is installed on the main valve body upper-end surface, uses set screw to fix; When main valve body and the combination of interior inlay, the one side of pad contacts with the flanged surface of main valve body, and another side contacts with the adpting flange of interior inlay, and first bolt is screwed into first tapped hole, and second bolt is screwed into second tapped hole.
Be provided with circular duct in the main valve body, at its front-end face first bolt, second bolt, locating stud be set, valve rod passes circular channel and contacts with the final drive mechanism cam of EGR valve by the top cap.
The upper end of interior inlay arranges adpting flange, and the lower end arranges suction port, and the side sets out gas port; From the upper-end surface of adpting flange, set gradually valve spring counterbore, outside framework oil seal counterbore, guiding copper sheathing installation through hole at interior inlay; First tapped hole, second tapped hole, positioning pin hole are set on the adpting flange; In addition, also be provided with two standby mounting holes; First bolt and first tapped hole are adaptive, and second bolt and second tapped hole are adaptive, and locating stud and positioning pin hole are adaptive; In guiding copper sheathing mounting hole the guiding copper sheathing is set, and sets gradually outside framework oil seal, valve spring, spool and suction port are adaptive; One end of valve spring contacts with the valve spring counterbore bottom surface of interior inlay, and the other end contacts by spring seat, and split washer is installed in groove place and the holddown spring seat of valve rod.
The present invention can reach following beneficial effect after adopting technique scheme: electronic EGR valve is divided into main valve body and interior inlay two-part design, use connecting bolt to make up, utilize locating stud to guarantee that the central axis position of interior inlay is accurate, the convertibility of inlay in realizing, need not to change any component on the main valve body, just can mate motor in the bigger discharge capacity scope by changing different interior inlays and spool, both increased the flexibility that the confined space is arranged on motor of electronic EGR valve, avoid designing the electronic EGR valve of multi-series again, thereby saved cost of production.
