Description
Technical field
The utility model belongs to security fields, is related to a kind of buffer-type explosive flame partition apparatus.
Background technology
It is huge in imflammable gas, dust market segment, industrial market space.According to incompletely statistics, at present China have it is super
The business for crossing 60,000 enterprises is directed to the production of industrial imflammable gas dust, stores, transports.In recent years, there occurs a lot of gas
Body, dust explosion accident, cause huge life and property loss.But it is a lack of effective blast control equipment.Buffer-type is quick-fried
Fried flame partition apparatus is one of effective blast control equipment, quick-fried for will occur in imflammable gas, dust booster road
Fried flame cut-off, so that after explosive flame can not propagate to device, the pipeline and system of protection device back.The technology is in state
Inside belong to blank.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of buffer-type explosive flame partition apparatus.
To reach above-mentioned purpose, the utility model provides following technical scheme：
Buffer-type explosive flame partition apparatus, including shell and be arranged in shell sleeve arrangement, valve element, valve element bottom
Seat, resetting means and positioner, the valve element branch sleeve device, the sleeve arrangement connection resetting means can be in shell
Axial movement, and positioned by positioner.
Further, the sleeve arrangement includes sleeve and valve rod, and the valve element connects valve rod, and the valve rod can be in sleeve
Axial movement, and positioned by positioner.
Further, the positioner includes locating rod and the locating slot being arranged on valve rod.
Further, the valve element on valve core base with being correspondingly provided with seal.
Further, the positioner is two, is arranged on the both sides of sleeve arrangement.
Further, the resetting means is two, is arranged on the both sides of sleeve arrangement.
Further, the resetting means is back-moving spring.
Further, the both sides of the shell are provided with adpting flange.
The beneficial effects of the utility model are：The application acts installation and is applied to fuel gas, powder transfer pipelines, when
Explosion time occurs for gas or dust in pipeline, and by the effect of explosion wave, buffer-type explosive flame partition apparatus is quick
Shut-off, so as to prevent propagation of the explosive flame in pipeline, pipeline and system after protection device are not involved by blast, and raising can
Combustion property gas, the security of dusty industrial process, protect people's lives and properties from loss.Present apparatus work is completely using machinery
Principle, no electric component, operating cost is low, reliability is high.It ensure that device in explosion wave explosion wave and blast fire
Reset after the closing rapidly switched off in the time difference of flame, the sealing of quick closedown faying face, operating position fixing and action.
Brief description of the drawings
In order that the purpose of this utility model, technical scheme and beneficial effect are clearer, the utility model provides as follows
Accompanying drawing illustrates：
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail.
As shown in figure 1, the present embodiment buffer-type explosive flame partition apparatus, including shell 1 and the set that is arranged in shell 1
Wound packages is put, valve element 4, valve core base 3, resetting means 6 and positioner 2, sleeve arrangement include sleeve 7 and valve rod 5, the valve element
4 connection valve rods 5, the valve rod 5 can move axially in sleeve 7, and be positioned by positioner 2.Positioner 2 includes positioning
Bar and the locating slot being arranged on valve rod, locating rod is vertical with valve rod, is inserted by locating rod and positioning is realized in locating slot.Institute
The branch sleeve device of valve element 4 is stated, the sleeve arrangement connection resetting means 6 can be in shell interior axle to movement, and is filled by positioning
2 positioning are put, resetting means is back-moving spring.Positioner is two, and resetting means is two, is arranged at the two of sleeve arrangement
Side.Valve element can bidirectional-movement, two-way positioning and reset.There is the flange of connecting pipe shell both sides, and the outer barrel of locating rod is welded on
On shell, sleeve weld can combine closely in the support end of locating rod, valve element 4 with valve core base 3, good seal, valve element and valve
After core base 3 combines, positioner 2 is will automatically turn on, after revocation positioner 2 positions manually, it is logical that valve element 4 connects valve rod 5
Cross resetting means 6 and return to origin-location.Buffer-type explosive flame partition apparatus can be divided into more according to the difference of connecting pipe caliber
Kind model.
After blast occurs, shock is when the power on valve element 4 is more than 6 reset force of resetting means, the edge of valve element 4
Shock motion direction action (shock wave power is bigger, and valve element action is faster), when valve element 4 moves to the position of valve core base 3
And when being combined in place with valve core base 3, positioner, which starts, pins valve element 4, so as to which valve element 4 no longer moves, by blast impulse
Flame cut-off after ripple, after blast terminates, positioning function is cancelled manually, valve element 4 returns to origin-location by resetting means 6,
Wait and being acted explode next time after.Because the blast pipeline direction of propagation in the duct is possible from different both directions,
Therefore, valve element can bidirectional-movement, two-way positioning and reset.
Finally illustrate, preferred embodiment above is only unrestricted to illustrate the technical solution of the utility model, to the greatest extent
The utility model has been described in detail by above preferred embodiment for pipe, but those skilled in the art should manage
Solution, can make various changes, without departing from the utility model claims book institute to it in the form and details
The scope of restriction.
