Also have a kind of improvement as of the present utility model, the madial wall that the Sealing of described spool both sides contacts with spool is equipped with scrobicular ring; The outer side wall of described Sealing is equipped with stress reduction face.After adopting this kind of structure, described scrobicular ring both sides contact with spool face, form two seals circle, also reduce the area of contact between Sealing and spool simultaneously, namely meet the seal action between spool and Sealing, also reduce open and close torque simultaneously, make Spool rotating more flexible, when user is used, energy easily rotatable handle, more convenient to use.The pressure suffered by Sealing can be alleviated in described stress reduction face, makes structure more reliable.
Also have a kind of improvement as of the present utility model, the scrobicular ring on described Sealing is arc scrobicular ring, and the dual-side of described arc scrobicular ring contacts with described spool face; The middle part in the stress reduction face on described Sealing is provided with right angle groove.After adopting this kind of structure, the dual-side of arc scrobicular ring contacts with spool face, and the moment of torsion between Sealing and spool is less.Described right angle groove can be released the pressure, and can reduce Sealing compressive deformation.
Also have a kind of improvement as of the present utility model, the middle part of the madial wall that described Sealing contacts with spool is provided with semicircle scrobicular ring; Stress reduction face on described Sealing is R edged surface.After adopting this kind of structure, the both sides of first circular scrobicular ring of Sealing contact with spool face, and the moment of torsion between Sealing and spool is less.Stress reduction face on described Sealing is R edged surface, can reduce Sealing compressive deformation.
Also have a kind of improvement as of the present utility model, the madial wall that the Sealing of described spool both sides contacts with spool is equipped with the arc shaped surface tangent with described valve core outer surface; Stress reduction face on described Sealing is inclined-plane.After adopting this kind of structure, place tangent between described Sealing and spool is linear contact lay, and the moment of torsion between Sealing and spool is less.Stress reduction face on described Sealing is inclined-plane, can reduce Sealing compressive deformation.
Also have a kind of improvement as of the present utility model, the madial wall that the Sealing of described spool both sides contacts with spool is equipped with conical surface; Stress reduction face on described Sealing is inclined-plane.After adopting this kind of structure, be linear contact lay between described Sealing and spool, the moment of torsion between Sealing and spool is less.Stress reduction face on described Sealing is inclined-plane, can reduce Sealing compressive deformation.
Also have a kind of improvement as of the present utility model, the madial wall that the Sealing of described spool both sides contacts with spool is equipped with the R edged surface tangent with described valve core outer surface; Stress reduction face on described Sealing is inclined-plane.After adopting this kind of structure, be linear contact lay between described Sealing and spool, the moment of torsion between Sealing and spool is less.Stress reduction face on described Sealing is inclined-plane, can reduce Sealing compressive deformation.
