The guide post coordinated with valve element sliding.
By using above-mentioned technical proposal, guide post is set up, valve core inside is given when valve element shakes against reduction is because being situated between
Vibrations produced by matter impact, further make runner ensure that the flow of stabilization is controlled, secondly, can be according to the end position of guide post
Determine that valve element seals being accurately positioned when coordinating with seal spool hole.
The utility model is further arranged to：Described runner is provided with positioned at valve element with respect to the opposite side in seal spool hole
Dielectric cavity is stored, and described runner is provided with positioned at outlet side and medium is guided to the inverse drainage face for storing dielectric cavity.
By using above-mentioned technical proposal, storage dielectric cavity is set up, storage dielectric cavity can be directed to when medium counter flow,
Medium temporary storage cavity extrudes valve element to the direction in seal spool hole, so as to realize the function of preventing from flowing backwards.
The utility model is further arranged to：Described valve element is located between the installation place of valve rod and valve rod and is provided with medium
Temporary storage cavity, is provided with the linked hole by medium temporary storage cavity and outlet side UNICOM on described valve element.
By using above-mentioned technical proposal, medium temporary storage cavity is set up, medium is increased when medium counter flow to valve element
Squish area, reduces the required duration of valve element and valve element closure, and increase prevents the reaction rate of adverse current, so as to increase practicality.
The utility model is further described with reference to the accompanying drawings and detailed description.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model specific embodiment.
