Abstract
The linear electric control valve for waste gas circulation of diesel engine consists of valve body, valve seat, valve, connector, armature and compressing device. The connector connects the valve body and the valve seat, the compressing device compresses the valve to close, and the coil in the valve body produces magnetic field to move upwards to open the valve to allow waste gas from the air inlet to exhaust from the outlet. The valve of the present invention can be opened and shut in high speed, continuously and instantaneously, has relatively large air inlet and outlet diameter, relatively large duty ratio, and may be used in waste gas circulating system in diesel engine.
Description
Affiliated technical field
The present invention relates to a kind of electrically-controlled valve, especially in the diesel exhaust circulatory system, can obtain linear electrically-controlled valve than big space rate.
Background technique
Common electrically-controlled valve is an automatically controlled medium switch, reach opening or closing of valve by the effect of electromagnetic coil, but the dutycycle of this valve is very little, promptly can not be at a high speed, continuous, instantaneously open and close, so can not be used for the diesel exhaust circulatory system.The electrically-controlled valve of using in existing egr system, excessive because of the back pressure of valve, open valve is very difficult, so can only be used for petrol engine.
Summary of the invention
In order to overcome the defective of common electrically-controlled valve and petrol engine egr system electrically-controlled valve, reach bigger dutycycle, valve can be opened like a cork, the invention provides a kind of linear electrically-controlled valve, can satisfy the needs of diesel exhaust loop control.
The technical solution adopted for the present invention to solve the technical problems is: this linear electrically-controlled valve is made up of valve body, valve seat, valve, coupling arrangement, armature, hold down gag, coupling arrangement is linked together valve body and valve seat, hold down gag compressing valve closing, the magnetic field that coil in the valve body produces makes the armature Open valve that moves upward, cycle gas is entered by suction port, discharges from valve port during valve opening.
The invention has the beneficial effects as follows that under the synergy of hold down gag and coil, valve can be at a high speed, continuous, instantaneously open and close, and the diameter of suction port and valve port is bigger, has reached bigger dutycycle, can be used for the diesel exhaust circulatory system.

Fig. 6 is the plan view of Fig. 5.
Among the figure, the 1st, valve body, the 2nd, valve seat, the 3rd, hold down gag, the 4th, valve, the 5th, coupling arrangement, the 6th, armature.
Embodiment
In Fig. 1, coil 1-1 is clamped by upper cover plate 1-3 and lower cover plate 1-7, connecting sheet 1-4 is fixed among the upper cover plate 1-3, upper cover plate 1-3 goes up also has spring seat 1-5, spacer 1-6 separates coil 1-1 and armature 6, respectively have two holes to scurry out for the lighting outlet of coil 1-1 in the relevant position of upper cover plate 1-3 and spring seat 1-5, case 1-2 is with the naked valve body 1 of forming of above-mentioned each part bag together; Be arranged among the spring seat 1-5 spring 3-2 with went here and there the push rod 3-1 of connecting sheet 1-4 and the packing ring 3-3 that is enclosed within on valve 4 one ends and formed hold down gag 3; Guide sleeve 2-2 is installed on the valve body 2-1, and screw 2-5 and packing ring 2-6 are pressed on guide sleeve 2-2 on the valve body 2-1 by asbestos packing 2-4, valve seat lid 2-3, form valve seat 2; The body of rod string of valve 4 is crossed guide sleeve 2-2, and armature 6 was gone here and there in its upper end, fixes with cover packing ring 3-3 riveted thereon; Armature 6 is installed in the spacer 1-6, and upper and lower end is respectively by valve 4 and packing ring 2-6 location; Valve body 1 is connected into one with valve seat 2 by the coupling arrangement 5 that setting sleeve 5-1 and screw 5-2 form.
In the work, cycle gas enters suction port 2-7, and coil 1-1 gets when electric, because the effect in magnetic field is risen armature 6, drives valve 4 and opens, and waste gas is by valve port 2-8; During coil 1-1 dead electricity, because the effect of spring 3-2, hold down gag 3 descends valve 4 and cuts out, and waste gas can not pass through valve port 2-8.
In Fig. 2, the valve of valve 4 back of the body 4-1 does tapered, has reduced the lateral pressure of cycle gas to valve 4, and the opening force of valve 4 is reduced greatly; The upper end 4-2 of valve 4 and packing ring 3-3 can be that riveted is fixed, and also can be that screw thread is fixed.
In Fig. 3 and Fig. 4, a pit 6-1 respectively is at the two ends of armature 6, and hole 6-2 is scurried in pit 6-1 bottom, and scurrying hole 6-2 can be one to five, is used for the air ventilation of armature 6 when moving up and down.
In Fig. 5 Fig. 6, there are two hole 1-5-1 to be used for scurrying out of coil 1-1 lighting outlet on the spring seat 1-5, also can be a pit 1-5-2 in the relevant position of spring seat 1-5 and be used to install the lighting outlet wiring base.
