Abstract
The utility model discloses an assembled electric EGR valve comprising a valve seat, a sensor, a motor and a reduction gearbox arranged on the valve seat, wherein, a socket is arranged on the sensor, the reduction gearbox, the sensor and the casing of the motor are connected with one another through mounting holes and screws, four mounting holes are provided, the central holes of the four mounting holes are arranged in a square, and a driven gear in the reduction gearbox, a transition gear and a driving gear at the front end of the motor are meshed with one another. As the four mounting holes for the casing of the motor, the valve seat and the sensor are arranged in a square, a power source can be mounted on the valve seat 1 upwards, downwards, leftwards or rightwards, and a sensor connecting plug which is assembled with the power source to form a whole can be adjusted upwards, downwards, leftwards or rightwards with respect to the valve seat, so that the universality of a part is increased.
Description
Technical field
The utility model relates to a kind of electronic EGR valve.
Background technique
Electronic EGR valve organically combines with other control system of motor as a system that reduces engine exhaust emission, has been widely used on all kinds of carrier machine motors such as automobile, boats and ships.
Present electronic EGR valve adopts direct current generator mostly, controls the motion of spool by 2 grades of gear reductions.Sensor connection-peg and valve body adopt same secondary mold injection, are integral piece.On electric machine casing, direction can't freely change valve body by screw.Therefore, when requiring valve body plug connector direction to change, just can't meet the demands, if connection-peg will change direction, generally valve body will be opened a secondary mould again, versatility difference and increase cost.
Summary of the invention
Technical problem to be solved by this invention provides a kind of sensor connection-peg direction and can change, the electronic preferably EGR valve of versatility.
Technological scheme of the present invention is:
The electronic EGR valve of a kind of assembling type comprises valve seat, sensor, motor, is arranged on the speed reducer on the valve seat, sensor is provided with socket, the housing of speed reducer and sensor and motor is connected by mounting hole and screw, and the quantity of mounting hole is 4, and the center hole of 4 mounting holes is apart from being square.
The driving gear of driven gear, transition gear and motor front end in the described speed reducer intermeshes.
Beneficial effect: the mounting hole of electric machine casing and valve seat and sensor is designed to 4, and be square profile, like this power source up and down 4 directions be contained on the valve seat 1, the sensor connection-peg that is assembled into one with power source with respect to valve seat just up and down 4 directions regulate arbitrarily, to satisfy the demand of different clients to the connection-peg all directions, and need not to have increased the versatility of part like this, and reduced cost because directionality problem is reopened mould.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
The electronic EGR valve of a kind of assembling type, comprise valve seat 1, sensor 6, motor 10, be arranged on the speed reducer 4 on the valve seat 1, sensor 6 is provided with socket 13, the housing 11 of speed reducer 4 and sensor 6 and motor 10 is connected by mounting hole 14 and screw 8, the quantity of mounting hole 14 is 4, and the center hole of 4 mounting holes 14 is apart from being square.
The driving gear 15 of driven gear 3, transition gear 12 and motor 10 front ends in the described speed reducer 4 intermeshes.
It is fixed that rivet clasp is revolved by motor bonnet 7 in motor 10 rear ends, is provided with seal ring 5 between the housing 11 of speed reducer 4 and sensor 6 and motor 10, makes that sealing effect each other is better, tightens behind the pocketed springs packing ring 9 on the screw 8 again, comes off to prevent screw 8.The opposite side of valve seat 1 is provided with valve seat cover plate 2.
The mounting hole of electric machine casing and valve seat and sensor is designed to 4, and be square profile, like this power source up and down 4 directions be contained on the valve seat 1, the sensor connection-peg that is assembled into one with power source with respect to valve seat just up and down 4 directions regulate arbitrarily, to satisfy the demand of different clients to the connection-peg all directions, and need not to have increased the versatility of part like this, and reduced cost because directionality problem is reopened mould.
