Description
Technical field
The utility model relates to safety of sympathetic initiation technical field, the flame proof valve of specially a kind of anti-high pressure of against shock.
Background technique
The flame proof valve used that circulates in the market has normally opened and normally closed type.Wherein open in usual is to utilize gravity drop hammer to the weight of flap
Power carries out component so that the structure that flap is opened.Explosion time, since flap will overcome reversed resistance during the shutdown process, from
And cause to close not in time, high temperature pressure involves flame and is likely in flap closing process by causing fire spreading, can not
Timely flame proof；Wherein normally closed type flame proof valve, because it relies on the circulating pressure of dust to open flap in normal work, to reduce
The crushing caused by operating system, usually the weight saving of flap, this results in the antidetonation strength of flap greatly to be limited
System；Flame proof valve in the market is to prevent flame proof valve flap turn-off transient from trembling, and usually increases mechanical locking device in hull outside.
When equipment is run, the flap of the vibration transmission that is generated due to impulse electromagnetic valve on deduster and blower to flame proof valve, flap is trembled
In it is easily dead by false-lock so that equipment cisco unity malfunction.And the rocking bar of locking device is easy to be failed or hindered by external interference
Hinder the closing of flame proof valve.After flap is locked can only manual reset, since flame proof valve is mostly mounted on high-altitude, this also brings to user
It is greatly inconvenient；The flap of flame proof valve in the market generallys use the nonmetallic mode to metal with inlet tube and is sealed；Valve
It is easy shearing nonmetallic sealing strip when valve is closed, sealing effect is damaged, for this purpose, it is proposed that a kind of flame proof of the anti-high pressure of against shock
Valve.
Utility model content
The purpose of this utility model is to provide a kind of flame proof valves of the anti-high pressure of against shock, to solve in above-mentioned background technique
The problem of proposition.
To achieve the above object, the utility model provides the following technical solutions: a kind of flame proof valve of the anti-high pressure of against shock, packet
Entrance steel pipe and explosion-proof valve body are included, is nested on the right side of the entrance steel pipe and pushes up bubble sealing strip, before the explosion-proof valve body
Rear end is provided with single direction rotation damper, is provided with rotary shaft between the single direction rotation damper, before the rotary shaft
The front and back side wall of explosion-proof valve body is run through in rear end, and the outer wall of the rotary shaft is welded with flap.
Further, the groove to match with entrance steel pipe is provided on the left of the top bubble sealing strip.
Further, the flap includes sealing plate, and foamed aluminum sheet, the sealing plate are provided at the top of the sealing plate
Pass through silica gel viscose glue between foamed aluminum sheet.
Further, the sealing plate is foam sponge sealing plate.
Further, the single direction rotation damper is reed-type damper or fluid pressure type damper.
Compared with prior art, the utility model has the beneficial effects that
1. the soft sealing material between flap and entrance steel pipe is easily sheared brokenly due to the impact of blast pressure wave
Bad, the utility model is using soft to soft sealing, and entrance steel pipe is buffered using top bubble sealing strip, can enhance sealing function
And protect sealing strip；
2. flap uses lightweight high rigidity foamed aluminum sheet, foamed aluminum sheet can disperse surge, and anti-high blast pressure subtracts
Light crushing, and there is good thermal insulation effect；
3. the locking device now used is easy by external interference and flame proof failure, the utility model is in valve to solve this problem
Single direction rotation damper is installed at valve rotary shaft, not by external disturbance, is not required to manual reset, and convenient for the user to operate；
4. the utility model accessory is simple, manufacturing process steps are simplified, easy for installation, and production cost is low.

Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 1-3 is please referred to, the utility model provides a kind of technical solution: a kind of flame proof valve of the anti-high pressure of against shock, including
Entrance steel pipe 1 and explosion-proof valve body 2, the right side of entrance steel pipe 1 are nested with top bubble sealing strip 3, top bubble sealing strip 3 and entrance steel pipe
It is pasted between 1 using silica gel or other viscous gum matter, the front and back end of explosion-proof valve body 2 is provided with single direction rotation damper
4, rotary shaft 5 is provided between single direction rotation damper 4, and the front and back side of explosion-proof valve body 2 is run through in the front and back end of rotary shaft 5
Wall, the outer wall of rotary shaft 5 are welded with flap 6.
As shown in Figure 1, the left side of top bubble sealing strip 3 is provided with the groove to match with entrance steel pipe 1, convenient for top bubble sealing strip
Connection between 3 and entrance steel pipe 1；
As shown in figure 3, flap 6 includes sealing plate 61, the top of sealing plate 61 is provided with foamed aluminum sheet 62, foamed aluminum sheet 62
Foaming size and density can be adjusted according to antiknock pressure, the shape of borehole can be rule or irregular shape, sealing plate
By silica gel viscose glue between 61 and foamed aluminum sheet 62, the shape of flap 6 can be round, rectangular or oval；
As shown in figure 3, sealing plate 61 is foam sponge sealing plate；
As shown in Fig. 2, single direction rotation damper 4 is reed-type damper or fluid pressure type damper, hindered by single direction rotation
Buddhist nun's device 4 can not influence the closing velocity of flap and play shockproof effect of exploding.
Embodiment: when dust pelletizing system does not work, flap 6 is fallen after rise, is bonded, is protected with the top bubble sealing strip 3 on entrance steel pipe 1
Hold sealing state；When dust pelletizing system works normally, the continuous aspiration pneumatic of blower, so that there is pressure difference in 6 two sides of flap, valve at this time
Valve 6 is opened, and flap 6 is acted on during opening by the speed limit of single direction rotation damper 4, it is ensured that flap 6 and limited block it
Between will not generate spark because clashing；When cleaner operation irregularity explodes the case where, pressure flame impingement wave is very
Flap 6 is closed fastly, when flap 6 and top bubble sealing strip 3 are hit, deformation occurs plays buffer function, flap 6 for top bubble sealing strip 3
When having rebound trend, the damping control rebound of flap 6 that single direction rotation damper 4 generates at this time, so that flap 6 state is kept
Constant, the foaming constructed of aluminium of flap 6 prevents high temperature from propagating at sealing, ensure that the sealing of flap 6, when determining fray-out of flame
And after being handled, flame proof valve just can be used directly without resetting.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired
Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
