The buffer brake in tank that the spool of small cross sections product is born, the i.e. pressure of piston are much larger than the pressure of spool, the two
Between the transmission through piston rod, form " pressure containing " effect, thus piston by spool always firmly plug be pressed in valve seat among,
Ensure the closing seam No leakage effect of the blow-off valve.The a small amount of condensation water triggered by injection steam heated material, downlink
It wears spool guard and flows to hollow via-hole, it can not by the upper port of the powerful through hole that blows off of steam of lasting uplink in the through hole
In entering, when the steam pressure weakens, spool reed voluntarily pops into position screening envelope through hole upper port, obstructs the water and leads into hollow
Hole.In addition while above-mentioned steam injection, a small amount of steam enters from the respiratory slot of valve body in valve seat room, rising certainly on valve seat outer diameter
It encloses by the steam rising, closely touch the supporting surface of valve body and valve seat to the circle, so as to which occluding pressure steam is at motion gap
Escape.For pressure and temperature in tank up to setting value, reversal valve stops steam injection.
After the isothermal treatment for short time boiling period, adjustment reversal valve connects the upper and lower air cavity of cylinder, and the pressure in lower air chamber is steamed
Vapour instantaneously lets out upward air cavity and pressure is lost, under the vapour pressure in steam-explosion jar takes advantage of a favourable situation to promote spool and piston rod and piston quickly
Row, spool instantaneously depart from valve seat, and valve channel opens wide completely, which opens.Steam sweeps along material and a small amount of moisture content in tank
Gush out tank, moment release of pressure is quick-fried broken by material, is then dissipated from the large area space of four branch intercolumniations of valve to outside valve.Valve seat therebetween
Indoor steam also leaks therewith at respiratory slot, recovers relaxation normality from piston ring, steam explosion operation is completed.It repeats afterwards above-mentioned
Whole process carries out the intermittent continuous steam explosion operation of a new round.
Example 2, the steam injection of the process in advance enters valve closing seam and then conveying enters tank, steam injection enters the mistake of tank boiling material again
Journey is identical with example 1.Thereafter after warm boiling, (reversal valve is same for air cavity injection steam on cylinder for adjustment reversal valve
Step leaks the vapour pressure in lower air chamber), piston is acted on by upper air cavity vapour pressure, under driving the spool of piston rod and rod end quickly
Row, spool instantaneously depart from valve seat and open wide valve channel, and blow-off valve is opened.Steam sweeps along material and a small amount of moisture content to gush out in tank
Tank, moment release of pressure are quick-fried granular outside valve by material.The indoor steam of valve seat also leaks therewith at respiratory slot therebetween, extensive from piston ring
Relax normality again, and steam explosion operation is completed.It repeats afterwards and carries out intermittent continuous steam explosion operation.
