Lid, driving means, keying piston, described valve body is provided with water inlet and the outlet of medium circulation, and described valve body is positioned at water inlet
Be additionally provided with valve port at the friendship neighbour of outlet, described valve gap is located at above valve body, and the bottom of described keying piston is arranged in valve port
On, the lower free end of described keying piston is provided with Open-close sealing plate, and one end of described valve rod is located in valve body through valve gap,
Described driving means is located on valve rod upper free ends, and the lower free end of described valve rod is located at top and the keying opening and closing piston
Piston is flexibly connected, and has been additionally provided with the elastic component of top tight sealing effect between described Open-close sealing plate and valve body.
Improve further: described valve body is additionally provided with on the inwall between valve gap and valve port can prevent medium fluid
The sealed cylinder leaked outside, described keying piston can be on the inwall that be located at sealed cylinder of oscilaltion, and described sealed cylinder is corresponding
The position of valve body outlet is provided with effluent trough.
Improve further: between described keying piston and sealed cylinder, be provided with sealing ring.
Improve further: that surface of described Open-close sealing plate correspondence valve port is provided with sealing member.
By using preceding solution, the beneficial effects of the utility model are: this utility model Slow Close regulation valve has
Following advantage:
1, the lower free end of described valve rod be located at open and close piston top with keying piston be flexibly connected, described keying is close
It is additionally provided with the elastic component of top tight sealing effect between shrouding and valve body, when needing to close valve, has controlled valve rod and move upward, valve
When bar stretches fully upward, during elastic component standard-sized sheet, opening and closing piston can hold out against in regulation valve firmly with the elastic pressure of elastic component
Valve port on, play self-sealing effect, it is to avoid during closedown, sealing effectiveness is bad, used for a long time that to there will be closedown tight, pipe
The phenomenon of road water clock.
2, the position of this valve body outlet is higher than the position of valve port, uses reverse flow, inversely closes, during closedown,
The hydraulic pressure of water inlet, so that Open-close sealing plate is fitted on valve port more closely, plays the function of non-return.
3, it is additionally provided with, on valve body inwall between valve gap and valve port, the sealed cylinder that can prevent medium fluid from leaking outside,
The sealing effectiveness making this utility model regulation valve is the best, does not haves the water junction leakage from valve gap with valve body during use
Phenomenon.
