Detailed description of the invention
Below in conjunction with the accompanying drawings the present invention is described further.
As Fig. 1 is to pressure release reactor quiet shown in 8, and including kettle and pressure relief device A, pressure relief device A includes pressure release barrel
3, valve casing 1, spool 2 and the elastic component resetted for spool 2；
Being provided with the gas channel that connect internal with kettle bottom pressure release barrel 3, pressure release barrel 3 open top is arranged, valve casing 1
Sheathed and to be fixed on pressure release barrel 3 internal, form the gap 30 that supply stream passes through, pressure release barrel between pressure release barrel 3 and valve casing 1
3 are provided with the multiple steam vents 31 flowed out for air-flow, and steam vent 31 is along pressure release barrel 3 sidewall circumference annular array.
Spool in pressure relief device can be by air pressure jack-up, and when spool is by high pressure jack-up, valve opening is opened, by valve casing
Gas channel is connected with gap, gap and then shed in steam vent by the gas released.
Owing to spool can be controlled by elastic component, and it is to use elastic component to be controlled, therefore when intrinsic pressure slightly larger
When elastic pressure, valve opening can be opened, and quickly reactor internal high pressure is carried out pressure release, when intrinsic pressure less than elastic pressure
Time, spool sets back and is closed by valve opening, reaching the effect of pressure control voltage stabilizing.
Steam vent 31 arranges and along pressure release barrel 3 axle center array in the form of a ring in pressure release barrel 3 sidewall.Owing to high velocity air exists
When small holes or gap, air can be made to produce friction and vibrate, thus produce noise.Therefore, the present embodiment is by pressure release
Set up multiple thickly dotted steam vent on barrel 3, eliminate fricative phenomenon, reduce noise, make production environment the quietest.
Valve casing 1 outer wall is threaded connection with the inwall of pressure release barrel 3.Pressure release barrel 3 inwall is provided with female thread, valve casing 1
Outer wall is provided with external screw thread, and external screw thread engages with female thread.By screwed tight, valve casing 1 is rigidly secured to pressure release barrel 3
In.
Tight mechanism includes sealing ring 42, and tapered ring-type of sealing ring 42, sealing ring 42 is positioned at pressure release barrel 3 and valve casing
Between 1, valve casing 1 lower end compresses sealing ring 42, and in a tubular form, valve casing 1 lower end and the sealing ring place of compressing are provided with and seal in valve casing 1 lower end
The sealing chamfering 15 of circle taper fit.
The effect of tight mechanism is to increase the air-tightness of pressure relief device, makes all of air-flow all arrange in pressure release steam vent
Go out, it is to avoid air-flow produces noise through gap.The tapering of sealing ring 42 coordinates with sealing chamfering 15, can increase the face of sealing
Long-pending, improve sealing, and so that the horizontal and vertical equal sealing that can obtain strengthens.
The bottom of sealing ring 42 is additionally provided with horizontal washer 420, and the thickness of horizontal washer 420 is more than sealing ring 42 thickness, water
Plain washer is one-body molded with sealing ring.Due to valve casing be threaded into tighten time, downward pressure is relatively big, sets up level pad successively
Circle 420 can effectively compress bottom valve casing, and the valve casing effect of tightening is played preferably utilization, the thickness of horizontal washer 420
Thicker, it is to deal with compressing when valve casing is tightened, it is therefore desirable to thicker thickness is used for deformable seal.
Being provided with the closure gasket groove 34 being embedded for sealing ring in pressure release barrel 3, sealing ring 42 and horizontal washer 420 are all embedded at
In closure gasket groove 34, closure gasket groove 34 is tapered ring-type.
The effect of closure gasket groove 34 is when sealing ring 42 and horizontal washer 420 are by valve casing crimp, it is possible to completely
Full live whole closure gasket groove 34, the area making contact is bigger, effectively improves sealing property.Secondly, closure gasket groove 34 can
So that sealing ring and horizontal washer are played good fixation, during preventing valve casing from turning, sealing ring and horizontal washer run
Partially.
Pressure release barrel 3 top is additionally provided with the close annular groove 33 in top, is embedded with the close circle 41 in top, pushes up close annular groove 33 in pushing up close annular groove 33
In pressure release barrel 3 inwall, valve casing 1 is additionally provided with for the fixing top Mi Quan fixing bulge loop 14 in pushing up close annular groove.
In the present embodiment, there is the place in gap except bottom in valve casing and pressure release barrel, also top, therefore top is still
Sealing structure set up by needs.
Setting up the close annular groove 33 in top on the sidewall of pressure release barrel, place and push up close circle 41 in pushing up close annular groove 33, pushing up close circle 41 is
Usual endless sealing ring, when valve casing is tightened, the fixing bulge loop 14 of valve casing outer wall can hold out against pushing up close circle 33, prevents top
Close circle 33 comes off or offsets.
Valve casing 1 is internal is provided with the cavity volume 11 moved for spool 2 reciprocal telescopic, and spring and spool 2 are respectively positioned in cavity volume 11, hold
Chamber 11 sidewall is provided with the valve opening 10 connected with gap 30, and cavity volume 11 inner wall surface is additionally provided with bulge loop 13.The effect of bulge loop 13 is,
Spool, when by spring fight back in situ, can play a spacing effect, prevents spool from deviating from cavity volume, causes control valve to lose
Effect.
Spool 2 includes lead 20, and lead 20 is located at the top of spool 2, and spool 2 assumes a " convex " shape, and sets in cavity volume 11
Having the gathering sill 110 embedded for lead 20, return unit is spring, and lead 20 sidewall is located at by spring housing.
Lead 20 has two functions: first, is for keeping the spool direction when sliding, it is ensured that spool can edge
The axis direction of valve casing slides, and prevents skew, it is to avoid dislocation；Secondly, sheathed for spring, plays a limit to spring
Position effect, prevents spring from use offseting.
Due to pressure release barrel 3 with valve casing 1 when docking, still there is gap, many places, therefore pressure release barrel 3 and valve casing 1 it
Between be additionally provided with prevent gas leakage top sealing ring 41 and bottom sealing ring 42.At two, the effect of sealing ring is, it is possible to coordinates and lets out
Pressure cylinder wall 3 and valve casing 1 tighten effect, pressing sealing ring card jail tightly down in gap by valve casing 1, improve tightness,
Avoid air-flow to overflow in gap, noise occurs.
It is above the preferred embodiment of the present invention, former without departing from the present invention for the person of ordinary skill of the art
On the premise of reason, it is also possible to make some modification and improvement, these also should be regarded as protection scope of the present invention.
