Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described further.
A kind of pressure release reactor prepared for Entecavir as shown in Figures 1 to 6, including kettle and pressure relief device A, lets out
Pressure device A includes pressure release barrel 3, valve casing 1, spool 2 and spring.
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.
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.
The above is preferred implementation of the present utility model, for the person of ordinary skill of the art without departing from
On the premise of this utility model principle, it is also possible to make some modification and improvement, these also should be regarded as protection of the present utility model
Scope.
