Abstract
The utility model discloses a highly sealed electromagnetic valve of an automobile engine, wherein a coil component and an iron core shaft are arranged in a shell; three valve cavities are arranged in an aluminum shell; the upper valve cavity and the middle valve cavity are communicated through an upper truncation hole; the middle valve cavity and the lower valve cavity are communicated through a lower truncation hole; the bottom of the lower valve cavity is sealed through a sealing cover; an upper valve core is arranged in the middle valve cavity; a lower valve core is arranged in the lower valve cavity; the upper and lower valve cores are connected onto a valve rod; the valve rod is arranged in a vertical moving manner; a spring is arranged at the bottom of the lower valve core; under the action of the spring, the lower truncation hole is sealed by the lower valve core from the bottom; the upper truncation hole is sealed by the upper valve core from the bottom; and when the coil component is electrified, the iron core shaft acts to push the valve rod to move downwards. The highly sealed electromagnetic valve of the automobile engine disclosed by the utility model is characterized in that the upper valve core and the upper truncation hole are in line sealing; and the line sealing is formed because the conical surface of the upper valve core is mutually contacted with the arched chamfer on the lower end surface of the upper truncation hole. Compared with the conventional electromagnetic valve, the highly sealed electromagnetic valve of the automobile engine disclosed by the utility model has the advantages of being good in sealing reliability and good in working stability.
Description
Technical field
The utility model relates to a kind of solenoid valve of using in motor car engine.
Background technique
Traditional motor car engine solenoid valve, comprise the shell that is fixedly connected with, mounting disc and aluminum hull, be provided with coil block and iron mandrel in the shell, be provided with three valve pockets of upper, middle and lower in the aluminum hull, between uuper valve chamber and the middle valve pocket by on block the hole and communicate, between middle valve pocket and the lower valve chamber by under block the hole and communicate, the lower valve chamber bottom is sealed by capping, be provided with upper valve core in the middle valve pocket, be provided with lower valve core in the lower valve chamber, upper lower valve core is connected on the valve rod, the up and down setting of valve rod, the bottom of lower valve core is provided with spring, under spring action, lower valve core from the bottom under block the hole and seal, upper valve core seals from the bottom to blocking the hole, when coil block was switched on, it is downward that iron mandrel's action promotes valve rod.The solenoid valve of said structure, upper valve core and on block the face that is sealed into sealing between the hole, lower valve core and the lower sealing of blocking between the hole are similarly the face sealing, in the application process of reality, often the sealing effect of discovery face sealing is undesirable for we, sealing surface is destroyed easily, and simultaneously, also there is the job insecurity phenomenon in above-mentioned solenoid valve.
Summary of the invention
In view of the deficiencies in the prior art, the utility model provides that a kind of sealing reliability is good, the motor car engine solenoid valve of good operating stability.
For solving the problems of the technologies described above, the utility model takes following technological scheme to finish:
A kind of high leak tightness motor car engine solenoid valve, comprise the shell that is fixedly connected with, mounting disc and aluminum hull, be provided with coil block and iron mandrel in the shell, be provided with three valve pockets of upper, middle and lower in the aluminum hull, between uuper valve chamber and the middle valve pocket by on block the hole and communicate, between middle valve pocket and the lower valve chamber by under block the hole and communicate, the lower valve chamber bottom is sealed by capping, be provided with upper valve core in the middle valve pocket, be provided with lower valve core in the lower valve chamber, upper lower valve core is connected on the valve rod, the up and down setting of valve rod, the bottom of lower valve core is provided with spring, under spring action, lower valve core from the bottom under block the hole and seal, upper valve core seals from the bottom to blocking the hole, and when coil block was switched on, it is downward that iron mandrel's action promotes valve rod, it is characterized in that: upper valve core and on block the linear sealing that is sealed between the hole, the conical surface that this linear sealing is provided with by upper valve core and on block the arc angling that the lower end surface, hole is provided with and be in contact with one another and form.Lower valve core and the lower sealing of blocking between the hole are similarly linear sealing, the conical surface that this linear sealing is provided with by lower valve core and block the arc angling that the lower end surface, hole is provided with and be in contact with one another and form down, and the lower endoporus that blocks the Kong Weitong mold insert, the copper mold insert is fixedly installed in aluminum hull.Being provided with equalizing orifice between uuper valve chamber and the lower valve chamber communicates.
In the technique scheme, we with upper valve core and on the sealing blocked between the hole change linear sealing into, also change lower valve core and the sealing of time blocking between the hole into linear sealing equally, thus Effective Raise the sealing reliability of solenoid valve.In addition, the setting of equalizing orifice between upper lower valve chamber, the action stability in the time of can improving upper lower valve core open and close makes the good operating stability of solenoid valve.
Description of drawings
The utility model has following accompanying drawing:
Fig. 1 is structural drawing of the present utility model,
Fig. 2 is the I section enlarged view among Fig. 1.
Embodiment
Accompanying drawing has represented the technical solution of the utility model and embodiment, and the below further describes each details and the working principle thereof of embodiment more by reference to the accompanying drawings.
As shown in the figure, high leak tightness motor car engine solenoid valve of the present utility model, comprise the shell 1 that is fixedly connected with, mounting disc 2 and aluminum hull 3, be provided with coil block and iron mandrel (prior art is not shown in FIG.) in the shell 1, be provided with three valve pockets of upper, middle and lower in the aluminum hull 3, between uuper valve chamber 4 and the middle valve pocket 5 by on block hole 8 and communicate, between middle valve pocket 5 and the lower valve chamber 6 by under block hole 9 and communicate, lower valve chamber 6 bottoms are sealed by capping 15, be provided with upper valve core 10 in the middle valve pocket 5, be provided with lower valve core 11 in the lower valve chamber 6, upper lower valve core is connected on the valve rod 7, valve rod 7 up and down settings, the bottom of lower valve core 11 is provided with spring 14, under spring 14 effects, lower valve core 11 from the bottom under block hole 9 and seal, upper valve core 10 seals from the bottom to blocking hole 8, upper valve core 10 and on block the linear sealing that is sealed in 8 in hole, the conical surface 10a that this linear sealing is provided with by upper valve core and on block the arc angling 8a that the lower end surface, hole is provided with and be in contact with one another and form, lower valve core 11 and the lower sealing of blocking 9 in hole are similarly linear sealing, the conical surface 11a that this linear sealing is provided with by lower valve core and block the arc angling 9a that the lower end surface, hole is provided with and be in contact with one another and form down, block down the endoporus of Kong Weitong mold insert 13, copper mold insert 13 is fixedly installed in aluminum hull 3, is provided with equalizing orifice 12 between uuper valve chamber 4 and the lower valve chamber 6 and communicates.
The utility model is like this work: when coil block is switched on, iron mandrel inhales movable property by magnetic force and vividly does, so it is downward to promote valve rod, upper lower valve core is opened simultaneously, and after the coil block outage, upper lower valve core seals blocking up and down the hole under spring-force driven dual again, owing to be linear sealing, so sealing reliability is good, the in addition setting of equalizing orifice has improved the working stability of solenoid valve.
