Structural Characteristic&Purpose.
This series
reducing valve is pilot piston type
reducing valve, mainly composed
of main valve and pilot valve. The main valve consists of valve
seat, main valve disc, piston, cylinder sleeve, and spring. The
piston valve consists of valve seat, valve flap, membrane, spring
and adjusting spring. Set the outlet pressure through adjusting
spring, sense the change of pressure of outlet with membrane,
adjust the flow area of throttling part of main valve through open
and close of pilot valve and drive the piston, to realize the
function of reducing and regulating valve. The product made
following improvement on the basis of normal pressure reducing
valve, enlarge the piston area, change the throttle structure,
change the sealing manner, improve the pilot structure and manner
of adjusting spring, thus to improve the performance of the
product.
1. Improve the
sensing effect to outlet pressure change, increase the sensitivity,
greatly reduce the pressure deviation caused by upper stream
pressure change and flow change.
2. Improve the
distribution of flow line, reduce the noise.
3. Improve the
structure of sealing surface; prolong the service life of sealing
surface.
The product is
mainly applied on steam piping, especially the steam piping with
big change of pressure and flow.
