Specific embodiment
The utility model is described in further detail with reference to embodiment, following examples are to the utility model
Explanation and the utility model is not limited to following examples.
Embodiment 1：
With reference to shown in Fig. 2, the present embodiment is by valve body 1, spring 2, armature 5, sealed steel ball 6, valve seat 8, sealing ring 9, shell fragment 3
Constitute with locating ring 4, valve body 1 is arranged on topmost, valve seat 8 is arranged on bottom, valve seat 8 is provided with sealing ring 9, armature 5 with
Valve seat 8 keeps coaxial, is provided with spring 2, is provided with sealed steel ball 6 between valve seat 8 and armature 5 between armature 5 and valve body 1.On armature 5
Locating ring 4, and locating ring 4 and 5 elastic conjunction of armature is provided with the outside of end.
When coil (not shown) no power, armature 5 is moved downward in spring 2 and the effect of shell fragment 3 lower edge X-axis so that close
Envelope steel ball 6 is contacted with 8 seal of valve seat, so as to close valve port.When the coil is energized, armature 5 is overcome under electromagnetic force
Shell fragment 3 and 2 active force of spring are moved upwards along X axis, so as to open valve port.
Locating ring 4 and armature 5 are elastic conjunction, and locating ring 4 is pressed into 5 tip portion of armature by frock, and which is pressed into deep
Degree can be adjusted, and can adjust 3 initial position elastic force of shell fragment by adjusting compression distance.Shell fragment 3 is filled for gap with armature 5
Match somebody with somebody, which is simultaneously contacted with 4 top of supply line of locating ring, another side is contacted with 1 end face boss of valve body, therefore, when armature 5 is in electromagnetic force
When moving on effect lower edge X axis, armature 5 drives locating ring 4 to move upwards, and locating ring 4 promotes shell fragment 3 to be deformed.Shell fragment 3
2 rigidity of spring significantly increase with its deflection, 2 rigidity of spring of spring 2 is definite value.Therefore, when the coil is energized, armature
5 must pull against spring 2 and the active force of shell fragment 3 is moved along X axis, and the electromagnetic force that coil is produced can be with valve body 1 and armature 5
Between gap reduction and significantly increase, traditional magnetic valve does not have shell fragment 3 and a locating ring 4, and armature 5 is only needed to gram in motoricity
Spring-force driven dual is taken, and the rigidity of spring 2 is a definite value, therefore, when armature 5 is moved along X axis, the power suffered by which is total
With can significantly increase, be unfavorable for the control to armature 5.The present invention increased shell fragment 3 and locating ring 4, locating ring at 5 position of armature
4 can adjust compression distance, and so as to adjust 3 initial position elastic force of shell fragment, the rigidity of shell fragment 3 is with the increase of its deflection
Significantly increase, therefore, when armature 5 is moved along X axis, the power summation suffered by armature 5 can keep a more stable value, from
And controllability of the coil to armature 5 is greatly improved, realize carrying out armature 5 suspension control, so as to realize the Linear Control to valve.
Embodiment 2：
As shown in Fig. 2 the present embodiment is similar to Example 1, which the difference is that only：
1st, also include longitudinally crossing oil groove 13 and horizontal oil groove 14 excessively.
2nd, longitudinally cross oil groove 13 to be arranged on the outside of armature 5, horizontal oil groove 14 excessively is arranged on the armature 5 of 2 bottom outside of spring
On.
Fig. 5 is main stress of the armature 5 in motion, has opened horizontal oil groove 14 and the longitudinal direction crossed and has crossed oil groove 13, protect on armature 5
In motion, braking liquid energy is crossing free-flowing between oil groove to card armature 5, so as to reduce the impact that liquid resistance is moved to which.
The technical characteristic for illustrating is not made in the present embodiment with reference to embodiment 1.
