The guide post that core sliding coordinates.
By technique scheme is adopted, guide post is set up, give valve core inside when valve element shakes against minimizing is because being situated between
Vibrations produced by matter impact, make runner ensure stable flow-control further, secondly, can be according to the end position of guide post
Being accurately positioned when determining that valve element is coordinated with the sealing of seal spool hole.
The present invention is further arranged to：Described runner is located at valve element and the opposite side in seal spool hole is provided with storage Jie
Matter chamber, described runner is provided with positioned at outlet side and guides medium to the inverse drain face for storing dielectric cavity.
By technique scheme is adopted, storage dielectric cavity is set up, storage dielectric cavity can be directed to when medium counter flow,
Valve element is extruded by medium temporary storage cavity to the direction in seal spool hole, so as to realize preventing the function of flowing backwards.
The present invention is further arranged to：Described valve element is provided with medium between the installation place of valve rod and valve rod and keeps in
Chamber, is provided with the linked hole of medium temporary storage cavity and outlet side UNICOM on described valve element.
By technique scheme is adopted, medium temporary storage cavity is set up, increase medium when medium counter flow to valve element
Squish area, reduces the required duration that valve element is closed with valve element, and increasing prevents the reaction rate of adverse current, so as to increase practicality.
The invention will be further described with reference to the accompanying drawings and detailed description.
Description of the drawings
Fig. 1 is the structural representation of the specific embodiment of the invention.
