Power, without twisting resistance, further to extend the service life of sealing ring.
Preferably, the cross section of the outer shroud deck is the middle concave with through hole.The structure causes sealing
The positioning of circle is more firm.
In order to prevent the destruction to flange and valve body caused by the inordinate rotation of servomotor, can be on the valve element
Defining flange is provided with, pad is set on the valve element and abuts on the seal；
Elastic component is provided between the defining flange and the pad.The revolving force of valve element is applied to pad by elastic component
On, skidding is produced, prevent revolving force to be delivered on sealing ring, further extend the service life of sealing ring；Meanwhile,
Using the cushioning effect of spring, it is to avoid because excessive the moving downward of valve element causes valve body by the problem of bursting when valve shuts.
Be the positioning of further robust seal part, can be provided with draw-in groove on the valve element, the draw-in groove be embedded with for
The fixture block of the spacing seal.
The pad is preferably metallic gasket or ceramic gasket.
Compared with prior art, water servomechanism provided by the present invention, it is to avoid current directly impact valve element, solve
Adjusting spool jitter phenomenon caused by water impact, even if in the case where pressure oscillation is larger, still being able to constant delivery port
Opening, so that constant output flow.
